Mobiles in SMP and the mods to make them work

[Arkaine23]

This thread is for information about specific dual AMD motherboards and using mobile Athlon XP's. Please post about your duallie board and mobile mods so we know the cpu mods each duallie board may require.

MSI K7D- This board requires you to break the 3rd L5 bridge on the CPU's in order to run the cpu's in SMP mode. Doing so also drops the multiplyer to a very low number, so you'll need to do a socket mod or use a TMC adapter to increase the multiplyer to a high number (12.5 is the max you can get in the bios on this board). Someone is working on a custom bios to try to enable MP capability without mods, but no testing has yet been reported.

Gigabyte 7DPXDPW-P- This board appears to run mobiles fine without breaking the L5 bridge, but runs them with a very low multiplyer. We are currently investgating whether the multiplyer can be changed via software such as Gcpuid while in windows. Otherwise a socket mod or adapter would be necessary to increase the multiplyer. Confirmed.

Asus AM7266-D- Early reports indicate the bios 1010 for this board doesn't recognizes mobile cpus as MP capable, yet it runs them in SMP at a low multiplyer, without having to break the 3rd L5. Windows shows 2 cpu's in task manager without an L5 mod using this bios. Socket mods can increase the default multiplyer fotr good overclocking. (woot! I have this board!)

Iwill MPX2- Have heard of users breaking the 3rd L5 to enable SMp capability and then modding the multiplyer and FSB for good overclocking.

Tyan 2460- User reports 3rd L5 bridge mod + pin mod to get mobiles working well on this board.

[diehrd]

Any one know what the MAX Multilpier has been on these chips in ANY dual Board ?

[Arkaine23]

I imagine the max is 24, set via socket mods or an adapter.

[mamisano]

Has the Gigabyte board been confirmed?? If so, I am going to be ordering some Mobiles :)

[emboss]

I've hacked the K7D bios to make it use the default FID and VID on boot instead of the max, and I'm in the process of trying to figure out any codepaths that could make it not enable SMP in the CPUs. I've also modded it to always think a chip is SMP capable, but I'm not sure whether that will help or not. Problem is, I'm too scared to use it on my board as I don't have any fancy dual-bios stuff to rescue it if it breaks. is there anyone out ther with a K7D and a dual-bios who would be interested in testing it? (after I complete the code-path analysis of course)

[cmcquistion]

Buy yourself a BIOS-Savior and give that new BIOS a shot. If it doesn't work, at all, you can use the BIOS savior, to flash your BIOS back.

[emboss]

The main problem is that there's no distributors of it in New Zealand, and I don't have access to a credit card at the moment.

I've found a place that will ship internationally, and even more surprisingly ship internationally for free on some items! (www.pcmods.com). And they also take PayPal. Unfortunately, the cost of the RD1-LPC2 is $21.09 (including handling) and I've only got $16.38 in my account. If there's someone with a spare $5.20 ($4.71 + paypal fees) then I'll quite happily try it myself :) One further issue is that they'll probably ship it surface which takes 1.5 to 2 months to arrive. So it'd be much faster if someone who already has one wished to give it a go.

[diehrd]

I am very intrested in the Giga-Byte board.I have 2 very decient MP2000+ that oc very well.However if the mobiles start at 1.45vcore and RUN with no mod in this board I cant even imagin how wild a clock speed is available.

Has it been confirmed in the Giga-Byte ? What bios was in the board that appears to have ran the mobile chips ? Thanks..

Ok, I'd like to give your bios a try. Getting mobiles to run in SMP without the L5 mod would be great, and having Powernow on a duallie = sweet.

[walaka7]

Ive made tbred b's work as mobiles and SMP in the asus dual. The powernow multiplier function works and of course the vcore does not. I'll order a couple of mobiles and try those as soon as i can get 2-5 hours of peace in my house.

A7m266-d ASUS mobo BIOS 1009
2*2400 AIUHB 0249 procs
no mods performed on board at this time
2nd 3rd and 4th L-5 closed
all L-11's factory closed (vcore)
all L-8's factory closed (mobile soft vcore)
all L-1's factory closed
L6's factory (or painted) closed (max multi)

[mamisano]

Okay, I can verify that the Mobiles work UNMODDED in the Gigabyte board. Clock defaults to 6x multiplier, I wire-modded the socket to 15x, now running 150mhz FSB = 2250Mhz.

[rxtrom]

What are the advantages running powernow instead of the pinmod?
Can i use the powernow with the pinmod?
I can see it being somewhat beneficial in the process of finding the max OC and then doing the pinmod, and getting rid of powernow
I have a K7D master
Thanks

ok thats it .
I have (will get) the GA-7DPXDW-P and just ordered 2 mobiles 2600+ , sold my 2 2800+ xps , got no experience at all in o/c and of course need help.

It is gone be a brand new setup , mobo is arriving next week , cpus in 15-20 days , allready got 2 x 512 MB Kingston@400, two 120GB h/disks , 2 x thermaltake volcano 9 fans+coolers , and cdrom ,dvdrom, nec2500 dvd+-rw.

I am planning to use 2 p/supplies one atx 400w for mobo cpus and h/disks , and one at (old) 200w that will open not via switch but via 2 small relays (don't know if it is the right word-I mean a kind of electromagnetic switches we use in closing car headlight circuit) so the 2nd p/s will open at the same time (msec later) with the 1rst, and will power the cddvddvdrw-roms and cooling fans and case fans.

I have never done any cut-bridge any pin mod just some easy o/c via bios or jumper settings on my other pc's , don't know how o/c on the fly works or where to get the apropriate software. I want to make it run high and stable so i really really need HELP HELP HELP to do any mod necesairy.

Please post any mod for the GA-7DPXDW-P and 2600+ mobiles
especially you mamisano or anyone willing to HELP HELP HELP.

[papaki63]

cmcquistion gave me on an older thread the first infos so i hope he will be also posting on that being polite and helpfull as he seems.

Please also someone tell me more about power now and where to get the software and if it changes the fsb and the multip...
Is it possible to change both on the air or fsb is a hardware related issue (amd chipset) ???

[emboss]

The K7D patched BIOS should be ready later today my time (as in about 12-14 hours from now). Remember this is a completely untested BIOS, so only use it it if you have a method to recover from a bad flash.

[cmcquistion]

papaki63, you should probably read these threads about mobile XP's and how to use them in duals.

Oh, could someone with working mobile duals post/pm WPCREDIT details, so I can compare them with the K7D settings.

[spldart]

Has anybody used the mobiles in an msi board with a multiplier higher than 15 yet?

[rxtrom]

I have them in my K7d with a multi of 16x150= 2400mhz working great!!!

Which models are you running? I'm trying to decide between the 2400, 2500 and 2600. I don't know if it's worth buying the 2600's if the max overclock can be had with a lower model.

[socrilles]

I've been lurking here recently thinking about trying the XP-M thing with my asus A7M266-D, finally had to go for it so I ordered 2 XP-M 2500+ from newegg, and got IQYHA stepping. Updated my bios to version 1010 and tried firing up the board with the mobile processors (in process of putting HSF I managed to chip one of the cores GOD )@%(@#$) anyway it still booted up at 600 mhz and on first boot said processors not MP capable, so I disabled the check loaded into windows and sure enough sandra is detecting both and is using both in benchmarks. I proceeded to do the wire socket mod to a 17X multiplier and it booted just fine at 2.26 ghz :) one strange thing though when it booted at 600 mhz i checked the vcore and 1 processor was 1.6 V and the other 1.5 V, but when booting at 2.26 ghz or 1.7 ghz the vcore is at 1.66 V for both without modding the voltage on either processor. So anyway I can confirm that bios rev. 1010 works for the a7m266-d with xp-m processors and i'm pretty sure my mobo revision is 1.03 hope this helps

[walaka7]

I ordered 2 xp-m 2400's yesterday and a rev 1.03 A7M266-D (to replace the one that died along with one tbred :rolleyes: ) So i will attempt mod identical to the tbreds to use powernow and get back to ya guys sometime in next two weeks. my birthday is today and dont know what is in store, also i have to go get my son in las vegas this weekend, also escrow on house should close today. therefor it might take me two weeks to actually get a 6 hour window needed for swapping the backup board out, installing new board, needs time for mishaps as well, also put badckup board back in its old case so it can continue to fold. ANd yes the one tbred that didnt die is folding @ 2.3 ghz in an old KR7A/R. So i also must take that board out before i can install my backup dual in its rightful home. The things we do when hardware takes a dump :D

[dustybyrd]

I ordered 2 xp-m 2400's yesterday and a rev 1.03 A7M266-D


Happy Birthday!


I too just got some 2600+ mobile chips a couple of days ago and they should be here any minute...

i also have the rev 1.03 A7M266-D, and i have already flashed the bios from 1011.03 to 1010 (this is the one know to work with the mobiles WITHOUT modifications on the mobile chips)...

by the way, when i flashed to 1010 with my current "true MP" 2600's that i have right now, windows XP taskmanager still shows 2 cpu graphs...even though the boot screen reports processors are not mp capable...

the 1011 bios reports them correctly, but either bios allows SMP function in windows at the correct speed: right now, 16x144 for 2.3ghz

i'll post my results once i get the mobiles in there....

[dustybyrd]

well, i flashed to the old bios 1010 on the Asus A7M266-D revision 1.03, then I modded the cpu sockets for 17x and 1.8v...

popped two 2600 mobiles in there....

and BAM! 2.26ghz no problem...the post screen reports that the cpu's are not MP capable...but that's not true...since i see two cpu graphs in task manager and sisoft reports and benches with both cpus...

a couple of things to note:

1.8volts with mobiles actually equals 1.775 volts...and this is because the mobiles tell the motherboard to set the voltage slightly differently than the regular xp chips...the chart for the conversion can be found here:

http://www.cpuheat.wz.cz/html/AXP_multiplier/AXP_Multiplier.htm

also, at 1.775volts i can run these chips at 17x142 or 2.4ghz so far without any problems...17x147 or 2.5ghz was not stable as it reboots in final stages of windows loading...probably needs a little more voltage...

[walaka7]

coolness.. I was using 1009 on my prior dually with modded tbrd-b's as mobiles and the 24x mod bypassing L6. they were recognized by their l3's (mp 2400's) in BIOS then in windows i used wpcredit and a version of cpuid to change multiplier once in windows. my goodies just came today. so im gonna see what revision the BIOS is on new board. if its 1009, or 1010 ill leave it be. i feel that at this time 1009 is best as it recognizes mp on any mp style mod ive made so far. also would like to confirm success in using true mobiles with rev 1009. more news to come

Thanks for b-day wishes. I cant tell you how many ways this day almost turned disasterous, but i managed to dodge the bullet everytime :whew: all in all its been a pretty good day :D

i am very curious as well about bios 1009...

i have read that bios 1011 does not allow both unmodded mobile xp's to work in SMP...

i know bios 1010 does with my own experience...but the post page reports that both cpus are not mp capable (even though they are) and it also reports the cpu's actual speed in mhz instead of the AMD rating like with the XP/MP cpu's

My rev 1.03 board has 1010 already on it. I saved the BIOS from my crapped out board to put in whatever board i got to replace it with and figured i would pop it in once i got things running. The BIOS is soldered on this board :mad: so to try 1009 on a rev 1.03 board i must reflash back to a 1009. I dont have a floppy i can steal ATM. OOPS am i spending my birthday modding my new comp??!! :D i cant spend too much more time on it though. I have other needs to attend to ;) anyhow revision 1009 recognized my xp2400's as mp 2400's when modded, and i had no issues with wpcredit or COUID in assisting with changing multipliers in windows. That being said:

I first just dropped the proc in unmodded and got the antisipated 800 mhz each and non recognized mp's. I popped off the hsf's and dropped some defogger in the middle L6 bridge to give me a max adj multi of 19x (quick and easy :D ) I then rebooted to windows @ 800 mhz each. I also set vcore to 1.7 on the board. i used wpcredit to "activate" powernow control. then used cpuid to change the multi's on each proc to 16 first, then 17. I tried 18 and got promptly rebooted by windows. I went back with 17X and its folding away as we speak. There are three CPUIDS that i have used and right now only one reports correctly Ill have to get into that another time and will notify the authors of these proiggies with my findings as well. One last thing.. im not happy with voltage control on the rev 1.03 the voltages are 1.70 on one proc and 1.61 on another. that is crappy control compared to my rev 1.04 which kept them pretty much even. Other than that, these mobiles are doing ok for what little work ive put into them so far.. more to come

wow, so many things to comment on:

i have read from at least one user with this board who said he could only change the multiplier in windows IF only one CPU was working...not in dual mode...how did you get this to work and are you sure you are using both CPUs?

what is the "max adjustable multiplier of 19x"?

how did you get powernow and wpcredit to work with cpuid to change the multipliers in windows? with both cpu's in dual mode?

what are these "three" cpuid's that you are talking about? and which one actually works?

i too have revision 1.03 and you can't get the board to increase the voltage to both cpus at the same time...i get around this by pin modding for 1.775 volts...you really only have to put in one wire...not like www.ocinside.de says...i.e. you must only make VID[4:0] 00011 instead of 01011...thus only the second 1 must be set to 0 by the pin mod...

[walaka7]

I may have to answer this in two different times, so whatever i miss right now i should be able to cover this evening.

First.. YES both cpus are controlled. With the rev 1.04 board you can do them one at a time. with rev 1.03 im not so sure. It appeared to do both on changing the first one but i changed both anyway.

There are two ways to control multiplier on mobile procs. The first, and one recognized by all, is to mod the L3 bridges either by painting the bridges to proper code, wire trick, or soldering the board. If you notice on your L3's that they are configured to 6X. this is why without mods the ASUS POSTS the procs @ either 600 or 800 mhz.

The second way, is to enable mobile mode (or in our case buying mobiles to begin with) with the proper L5 code. Now the L6 bridges come into play. The coding of the L6's dictates what the maximum multiplier CAN be during operation. This is how powernow is utilized in laptops. L3 becomes the lowest runnable setting while the L6 becomes max setting. Here's a great link that explains what the bridges mean and do:
http://fab51.netfirms.com/pc/barton/athlon-e24.html

Next: our boards can utilize powernow by changing the registry. The support was writtin into the chipset but not the BIOS. So what must be done is to change one entry in the registry with a program like WPCREDIT. The full answer to this will come later as i must get daughter ready for daycare and me for work. Or you can do a search on wpcredit in SMP forums and there are a couple of folks who figured this out and explained it quite well.

Ok, once the change has been made, you can utilize certain versions of CPUID to then change multiplier in windows. the version that works the best right now is crystal CPUID found at same site listed above. The_coolest has a great program here at oc-forums, but the rev 1.03 board didnt like it and doesnt report the changes correctly, the third, oh crap i brain farted :rolleyes: doenst matter anyway right now.. the best two are listed :D

In the "old" days we used CPUID to look at the specs of the processor. it was really neat when we were working on some propietary POS and didnt really know what was in it.
Now this same proggie has been modded to allow changing of the multiplier in either true or modded mobiles.

Your right about the voltage issue, i had read sometime before this was a problem on the 1.03. (i really miss my 1.04 RIP) I was in too big of a rush last night and didn't even think about that. funnt thing though, neither proc is running at "rated" voltage (1.45)
****zors i gotta run.. Ill finish as needed when i get home.. Have fun!!

[dustybyrd]

****zors i gotta run.. Ill finish as needed when i get home.. Have fun!! [/B]


first, it would be great if you could put a full post on changing the multiplier in windows with both cpus working in dual mode...

i have read a lot of posts where people tried, but failed to get this to work with both cpus functioning in SMP mode...



also, the reason these mobiles don't run at the "rated" voltage has to do with other bridges...

but, the "conversion" of what the mobile voltage would run in a desktop board can be found in a chart in the middle of this website:

1.8volts with mobiles actually equals 1.775 volts...and this is because the mobiles tell the motherboard to set the voltage slightly differently than the regular xp chips...the chart for the conversion can be found here:

http://www.cpuheat.wz.cz/html/AXP_m..._Multiplier.htm


the key difference is the last VID is a 0 instead of a 1

VID[4:0]=01011 for 1.45 volts on a mobile---BUT will run 1.575 on desktop

VID[4:0]=10000 for 1.45 volts on a desktop

if you follow www.ocinside.de guide for pin modding a Barton for 1.8volts for instance you will actually get 1.775v

[walaka7]

OK for 1st comment. I have no problem generating a post dedicated to the mods

required to make things happen in the two asus revisions ive done. I posted here

because arkaine appears to be compiling this info and will perhaps make a guide

concerning all most common dually boards. My post could only be about 2 boards in

paticular right now. Once i can get the new asus where the MSI is, i can play with

the MSI and figure out a way to make that work without pinmods or a hacked BIOS

and then perhaps be more help to folks with those boards. Im game for helping

anyway i can and if a mod or whoever makes the guide needs any help, by all means

pm me or post. Also if there are questions i can help with from anyone, shoot me a

pm as well. Thats what makes this site so great :D

Second.. I didnt use any bridge method for volt mod on the mobile, so there reported

voltage is 1.45 (and yes your right, that wont be exactly right either :) ) I used the

voltage control on the mobo for vcore changes i used 2-3 2-3 1-2 1-2 (P0 VID 1-4)

which is for 1.7 volts. This is what is reported in motherboard monitor and the BIOS

as well. the second proc, however was at 1.6x volts, (also not near reported 1.45 on

proc) My rev 1.04 didnt have this issue at all as the procs ran at whatever i set

them to.. mobile or not. So like you stated earlier, i will prolly need to pin mod the

second proc (or paint it) to get vcore right. wish i had more time right now to work

that out. Since i like to blow bridges instead of cut, mods need to be made to my

test leads ( i need to make them much MUCH sharper) to get below the top covering

to blow the bridges. Perhaps after the move.

if you want i can post or pm you the ONE wire that is needed to set these voltages at 1.775...it's not too bad when you only have to do one pin...if you want 1.825 or 1.85volts then you will need two or three pins respectively...

[THE JEW (RaVeN)]

Do you guys recommend cutting the L5 bridge or blowing it with the 5V line off your power supply?

[spldart]

I definitely say cut.
IMO

[dustybyrd]

Do you guys recommend cutting the L5 bridge or blowing it with the 5V line off your power supply?


see if you can get away with not doing either (depends on your mobo...i know the asus a7m266-d with bios 1010 doesn't require chip modding at all, even with both cpus in dual mode....maybe the gigabyte dual board also doesn't require chip mods)

from what i understand, cutting the bridge is probably safer if done under a microscope or magnifying glass...that is if you have to do it

[walaka7]

The thing about blowing the bridges is you CANNOT blow from the copper pins at surface. You MUST blow the bridge from underneath the surface. If this is not perfectly clear to you then by all means cut :D

[walaka7]

hows the MSI mods coming along?? I really look forward to seeing how this turns out. If my bonus is large enough this month, then i may get 2 more mobiles for the MSI. If the BIOS hack doesnt work out im thinking of some bridge mods that may. Possibly modding L6 to get into windows then running a jumper to the 24x (2nd L5) and closing it once in windows (the L5's can be live switched :D ) then you can have up to 24x freedom and live control of multi in windows. While im at it i wonder if there is a pin mod to control L5 in socket?? cause it would be no biggy at all to solder a switch to each socket on the mobo for L5. When i get back from vegas, Ill start looking into it myself. I know a lot of K7D's owners would love to have a viable answer for the mobile delima

I thought blowing it just entailed taking 2 pins, sticky them on the 2 "dots" of the bridge, and applying the 5v line? Ya hear the pop and you're done. Has this changed somehow?

I think that it is due to the new "coating" on the bartons that make it so the pins are no longer exposed w/o doing some scraping.

[walaka7]

the "copper" you see on proc are NOT connected to the actual bridges. If you get out a magnifying glass, zoomed camcorder, or if you have good close up vision, you can see that the copper is not connected to the bridges and that the circuitry actually "pops" up between the copper points. My guess is that AMD uses these for line up purposes only. Ive heard of folks using the copper and frying the proc so dont use the copper points as a means of blowing bridges and the newer packaged procs

[THE JEW (RaVeN)]

Cut it is then. ;)

I have folling Problem with my Assus duali i modded two new layout Bartons to MP-Mobil.

First strange thing is that i had to turn off MP Checking in Bios to get WIN 2000 regorgnise 2. Cpu.

Then wenn I use wpcredit and Z-CPUID to change MULTI to 18x its works stable but timing in many games are unuseble.

Any Idears or simmiliar Probs ?

On the old pcb athlons (pre week 15s I THINK) where except for the bridges there are no visibile traces, you can use the 5v way, in the visbile traces ones with totally covered dots and the fake points, there is a VERY high chance you will PERMINENTLY fuse the bridge together, you can keep the probes there 30 mins the bridge will not conduct electricity and will seem close to the CPU, just cut it, push the tip of a xacto knife into the bridge at an angle a TINY bit, watch the edges of the blade so they dont cut the traces between teh bridges (do that you have a dead cpu) and lift the blade out (you cut throught the trace then peeled it back), if you insultate the cut you made and opened up the bride piers you can close it again.

18x is getting up there. How much vcore are you giving them?

Also, you'd be hitting the major bottleneck of the chipset if you're at 18x133. Once you get above 2200 mhz or so, its limited memory bandwidth that hinders performance of an MP/MPX duallie, so more FSB or faster memory timings may help with stuttering.

[walaka7]

well sorry for delay in any help i may have been able to offer MSI folks.. I just lost a PSU this morning and the $$ i had set aside for another pair of mobiles just got spent on a true 480 (man i hate going to fry's.. $120 down the tubes $75 @ newegg) couldn't wait for newegg as i was right in the middle of stressing the thing to make sure it was stable enough to put in main rig this weekend. also didnt wann go cheap on PSU either and have another escapsade like the one i had last year where an allied failed and took out a mobo, roc, and memory
