Hey,
I am looking at getting a new Santa Rosa laptop and was curious about something. Intel has a T5450 (socket P 1.66ghz proc 667fsb) and the new 800mhz fsb processors. I am curious if anyone knows of a way to pinmod the 5450 to run at 800mhz fsb or of a good place I can try to research it myself.
TIA
I guess it would be called a BSEL pad mod, but pin mod sounds cooler...

upon looking at intel's data sheets for the socket P I've found this...
It looks like the 166mhz is between the 133 and 200 selection (I don't know why it says reserved though). Anyone think its possible to ground BSEL 0 to get it to go to 200mhz?

you could if you know the cpu will run at 200mhz fsb with out having to increase the cpu voltage.

It'll run that speed. heck the OLD 667 FSB Core 2 Duo on the 945 chipset would run at 1066. You'll have to bump the volts a bit to do it. I had 3.26 24/7 stable on my last T-series on the 975x ydg board from AOpen.

no there wont cause its just a "ID" pin to the mobo saying hey i run at 200mhz not 133 or 166.

well depending on the cpu no... if you have a socket M's
http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=2+50001157+40000343+1051723319&name=Socket+M
then no cause the chipset isnt designed to run that fast not even with a bios update.
Socket P
http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=2+50001157+40000343+1051728970&name=Socket+P
is another story you can search intel's cpu finder and see that they have socket P cpus on 667fsb. how ever you wont find them in retail form, i dont think we ever will.
Socket M cpus can not be used in Socket P and vise versa.

My processor I got with my Dell 1520 is a 1.5GHz Core 2 Duo (T5250) which uses the 667FSB (it is not santa rosa)....so if I could get 2.1GHz out of the chip by increasing the FSB to 200 that would be awesome!! Dell uses the same motherboard with the Santa Rosa processors, so it will be able to handle the FSB and I'm pretty sure the processor would be able to do that without any vcore adjustments. I just want to know if its possible

Well as soon as I receive my cpu and laptop you will know ps2cho. If I get it running I'll post a how to, it just may be a cheap way to get a decent cpu for a laptop.
and your cpu would be a 1.8ghz with the mod.

I just got this response from another forum.
Socket P (Santa Rosa platform i.e. 800MHz FSB) changed the pinout of socket M(667/533MHz FSB) by rotating the key 90 degrees. Socket M and Socket P are physically incompatible. There is no mod you can do to make them compatible.
Oh and yes 1.8GHz. My math is off today...dunno how I thought 200x9 was 2100 lol

@ps2cho
he is right but if you showed him you SS of cpu-z then he would have noticed that the socket is the P not M. Yes it is possible for you to pin mod to 200mhz from 166mhz, like i said before. not all socket P cpus are for sell in retail form, as far as santa rosa is concerned. that is the platform consiting of intel's latest wirelless nic's,800fsb mobile cpu,x3000 onboard video. the cpu is still a merom just like the socket M verision's. Intel only did the pin rotation to keep you from upgrading just the cpu alone.

Ok so would the BSEL pins be the same as a socket M pinmod then? and if it is: then how do I ground the BSEL[0] ? Wire it to the side or something?

well you cant use a "pen" to do it, socket p still has pins on the cpu. your gonna have to old skool it with the "wire" from pin to pin.
@ps2cho
the bsel connections yes but tring to use the pinout of the socket m for a socket p isnt gonna work. since the pins are rotated 90 degrees, we might have to wait for intel to release the socket p pin layout. im not sure where custom got that pic from. i do know they take a few months to get updated pdf's on pin layouts/bsel's for cpus.

Well custom: is that the correct socket P pin layout? Where'd you get it from?
Oh and also, with running the FSB at 800, would this cause the RAM to run at a higher frequency?

I see what you mean about pins Evil, for some reason I was thinking they would be LGA. I did the pin mod on my dothan 1.6ghz, so this should be similar.
As far as the data sheets I got them from Intel's website (http://www.intel.com/design/mobile/datashts/316745.htm). It says for Intel Core2 Duo Processors and Intel Core2 Extreme Processors for Platforms Based on Mobile IntelŪ 965 Express Chipset Family so it should be the correct one. There is also one for 945 series chipsets (http://www.intel.com/design/mobile/datashts/314078.htm).
I'd be willing to give it a shot right now if you can confirm the correct pins to connect. I don't think it will blow the CPU even if it doesn't work.

But after checking Intel's spec sheets i made this that want to try it.

YELLOW = BSEL PIN
BLUE = VSS PIN
Connect those 2 to force you 166mhz fsb cpu to run at 200mhz fsb.
Just so all that read this thread that pic of the cpu came from intels spec sheets in the 965chipset docs for Socket P.
Now if your cpu doesnt boot at 200mhz fsb then you either need to double check to make sure you got the right pins or you need to a Vid pin mod as well.

in the past the easiest way to get the wire in a u shape is to use tweesers. i always got one side of the wire in the socket then used the tweesers to made the bend into the other hole. you dont need a very long piece of wire, it needs to be really short so this will be alot harder to do.
or if you wanted remove the mobo of the laptop and do it to the pins on the pcb with some *Pen* or *defrogger kit*

if it works use crystalcpuid it has a voltage adjustment via software. give it a shot before tearing it a part to up the voltage. cause if crystalcpuid works then all you need to do is just have it startup on bootup.

Luckily I can run all the programs I need via taskmgr...so I'll give that a shot and we'll see what happens! if you can find the VID pin's that would be great while I try this.
Thanks to both you! VERY Happy to see it work! I think I'm the first person to do this on the Socket P platform!
It must be close to stable because otherwise it wouldn't let me run mozilla and paint etc...

nope thats the only one i have come across, it might have to do with windows vista though. im at work so i cant mess with editing pics, i can when i get home.
*edit*
if you can get into the bios disable the EIST/C1E states. Then go into the powermanagment window in vista and set it to always on/performnace. i see that C1E state is active cause your cpu voltage is 0.95v in cpuz.
can you run coretemp and get the vid of the cpu?

It doesn't seem to be doing anything. The multiplier's wont increase, the voltage won't and CPU is stuck at 6x. Explorer isn't crashing this time so I got it to run.
I'm not sure why it wont. It's stuck rock solid at 200x6. Other programs read it as 1.8GHz but CPU-Z doesnt and CrystalCPUID doesn't either.

yea give the pin mod a go agian and do a fresh install then... cause the only thing to cause data corruption would be not happy ram or pci bus speed out of spec. i dought it was the pci buss speed cause your telling the mobo what cpu fsb to run at and what trap. not the same as just ocing it in the bios with the 166fsb.

Well I think this will be the best gameplan: I will repartition tonight some of the drive and make room for another copy of vista.
Next pinmod again and right from the start just install a fresh copy of vista.
If all goes well then it should be running 1.8GHz no problems. If it fails and we hve the same problem -- I have the old vista to fall back on until we can do a VID mod too.
It takes a good 15minutes to take the laptop apart then another 15 to put back together. It's awkward too because I don't want to pull out some of the plugs because they lead behind the motherboard. Just wantd to make the procedure as easy as possible.
As you can see I have to take the whole lid off including the LCD.

The BIOS even reads 1.8GHz too. I'm HOPING it was the corrupt vista causing the stuck 6x multiplier.

Absolutely. I will mention names too :) Both you have helped me a lot -- I just took the risk and did it following your instructions.
As for the VID. Coretemp reads it as 1.3625v(i think its wrong) and CPU-Z reads 1.250v.

just remember that coretemp gives you what intel has set as the voltage the cpu needs to run at stock speed. what cpuz is giving you is the actual voltage , in some cases cpuz is not correct in reporting current cpu voltage. As well core temp does not give current cpu voltage its just what intel says it needs,via programmed into the cpu. imma take a look at the vid info later tonight and see what i can get worked up. as i think for the 200fsb we are gonna have to force the 1.35v ,via vid pin mods. this way you will know the cpu is stable and be well within intels vid for that cpu.

I think 300MHz overclock is within stock VID capability. Tomorrow will tell! It was obviously vista that was corrupted, so who knows if we will need any voltage mods.
The Orthos ran fine. 6hours 40mins no errors. CPU is fine :) Very pleased no damage occured so tomorrow is a go now! I'll be up nice and early to get this rolling. Gotta take an hour to wait for vista to install you see.

been an observer of pin modding for a long time without actually giving it a go (never had the correct hardware). This 6x multiplier problems sounds very similar to the Yonah pin mod attempt, trying to get a 533 to 667, bios read everything fine but as soon as windows booted up it was throttled to 6x.

Sorry for the lack of updates, had a lot of work these past fews days and haven't had much time.
I will probably give it a shot on thursday as I have the whole day to fiddle with it. (Disneyland on wednesday woot woot :D )
I am expecting as stated above the stuck 6x multiplier. But possibly this is a Vista problem or a CPU-Z problem. Only a benchmark can confirm the speed...which first I need a stable OS to test with. I just got my vista back to how I want it so I'll be partitioning to make sure I don't lose everything again.
And yes the thread: http://www.notebookforums.com/thread174106.html that you gave me explains exactly what I am getting too.
And yes I tried forcing the multiplier change with NHC as well and it didn't budge.

08-14-07, 07:12 AM
the stuck 6x multi is because you turned off "speedstep" or "Dynamic Acceleration" (can't remeber which exactly, experiment). Same happens on my laptop. With them off the system will run at its slowest possible speed. Its used to force the laptop to run that slow to save power all the time without mobility center. If you turn it back on the laptop should raise the multi again. I hope this is the problem. I would switch those two bios settings you flicked before back if you havn't already.

if it works use crystalcpuid it has a voltage adjustment via software. give it a shot before tearing it a part to up the voltage. cause if crystalcpuid works then all you need to do is just have it startup on bootup.
I think CrystalCPUID gives the illusion of allowing you to increase VCore above stock as when I tried it I found that the system power consumption didn’t increase under load which is the quickest and most direct way to test for VCore changes. Forget about what CPU-Z etc are saying, just measure the power draw.
It would be easier to attempt this with a mobile on desktop motherboard which is what I’m considering. Is it easier to mod the socket than the chip?
I’m considering this for socket M rather than socket P; 133 to 166 rather than 166 to 200.
BTW, if you increase the Vcore with a pin mod does Speedstep still function? I assume it will as all that’s changed is the maximum Vcore!
Evilsizer
08-16-07, 04:50 PM
yea speed stepp still will function. the only thing you are doing with pin mods is tellingh the mobo the cpu is a different speed then what intel has it set to. same thing with the volt pin mods it just tells the mobo to increase the cpu volts some more. is the best way to oc esp if you dont have the options in the bios. someone did this same thing with a dell computer, he pad modded his lga cpu to run at 1066 instead of 800 and also did the vid mod as well for more volts.
BTW, if you increase the Vcore with a pin mod does Speedstep still function? I assume it will as all thats changed is the maximum Vcore!
You will have to use CrystalCPUID or some such to set the voltages for Speedstep, otherwise it'll jump back to the old voltage.

you dont need crystalcpuid to set voltages for speedstep, C1E handles the voltages. the VID pin mod will tell the lappy what max voltage to use when the cpu is loaded that is if you dont have C1E disabled. if c1e is disabled then what ever voltage you pin modded to will stay that high. now if C1E stay enabled then the voltage will drop along with cpu speed when the lappy is idle.

That makes sense to me; the two pins mods are resetting the FSB and VID values and everything else stays the same.

There are no mobile chipsets that will support 1066 so modding it is not possible. Also intel locked it so if you try a pin mod you can't use your higher multipliers...

Thanks for the quick reply. Your right none of the other mobile core 2 duos have higher FSBs then 800mhz and Intel's 500 page PDF on the mobile 965 says nothing about 1066fsb or 266fsb. Well I guess I have one more hope and that is fining the PLL clock gen chip on my laptop.

Hello, everyone.
I'd like to say, that was researching the same issue and wrote two articles about BSEL mod. Now I'm here cause I was given a link from the BSEL mod topic on overclockers.ru forum, I'm moderating.
So, to the issue. I think the multiplier lowers because of the energy saving features. Or may be, because of the mobile CPU initialization routine.
All of them start at the lowest multiplier, and only then the MoBo sets their default value. That was the case, why the mobile 3,06 CPU worked on a desktop MoBo only with 12 multiplier. So you have to set the multiplier manually. This can be made by programs working with MSR. For example, CPUMSR or RMClock.

custom90gt
08-23-07, 01:03 AM
welcome to the forums. Unfortunately RMclock will not allow any type of multiplier/voltage adjustment. One weird thing is that you can't even view the memory settings via cpu-z. Its like the chipset is in safemode so to speak and you can't do anything.
Antinomy
08-23-07, 08:20 AM
Thanks. Bad for the RMClock, what about CPUMSR?
The memory settings may be so, because of the problems with strap switching, maybe unknown combination, due to not full switching to 200 bus. I haven't seen anything similar to safe mode in the 965 datasheet. Can you download MCHbaredit and post a dump of it in an attach? I could read it and look, what frequency strap is chipset working with so as for the timings and so on.

I will do that, but unfortunately I am away visiting a friend so the soonest I can do it is sunday.

I couldn't find any more information on what to change however to get it to work.

Can you post a quote about this? Didn't see anything similar. Only about the FSB swithcing, but all of them are connected to the BSEL, so should swith with it. Maybe only some specific registers, that should (but by obvious reasons weren't) be set up via BIOS.
ps2cho Thanks :) I'm sure it's not a hardware issue, cause then it wouldn't work with default FSB either. The problem is in the CPU registers. And they and the BIOS routine is the thing that should be figured out first of all.
On MoDT platform we on ROM.by forum couldn't make this work. But there are more chances here.

08-23-07, 09:09 PM
Yeah after looking at it again it seems they are connected to the bsel. I still don't know what is keeping it at the lowest multiplier. Its also weird that you can't modify VIDs or anything of that nature.
Antinomy
08-23-07, 10:29 PM
Yeah after looking at it again it seems they are connected to the bsel. :)
I think I know, what's keeping them on lowest multiplier. I'm almost sure it's the initialization routine. The issue is the next:
On startup, the processor loads at the lowest multiplier (it's the same for all CPUs of one series). Then, the BIOS sets the MSR to set the CPU default multiplier. And then it can be changed due to energy saving features.
So we should find out, what registers are being changed in initialization stage. And make this by our own, cause the BIOS doesn't know such a processor.

Not yet. It's not my program. It's Codered's (from XS). If the MCHbaredit can't work with it, it's bad. I won't be able to read the registers.
But there is a group of very expirenced BIOS specialists on ROM.by, like apple_rom. I'll ask him. Not soon, cause we are working on a new site engine.

To update anybody out of the loop in cliffs:

yes it will be its replacement but you can use the new 45nm cpus in the current GM965 laptop chipset. intel talked about the new 45nm and from what read for the chipset. its going to be the same and the same socket, intel wont change the socket for a while.
I just tried one on the reserved FSB settings by forcing BSEL2 high. I wired C21 to B20. Unfortunately, the lappie wouldn't even get past the power-up.

Hello,
Same problem here, i think so Merom FSB pin modding is "locked" by intel GM965 chipset & post / BIOS initialization routine.
Tried every BSEL "combinations", with these results:
1, notebook cannot boot
2, stuck at BIOS boot screen
3, *no change* in FSB
4, Only one - FSB "downgrade" works for me (Success...at 133MHz FSB).
@ Antinomy, very interesting idea. So if we need MSR registry report, BarEdit dump is enough for that?
Or which data concrete from MSR registers is important (to compare)? what we need, please?
Hello,
Same problem here:-( I picked up a T5200 for $10 and figured I'd give pin modding a try in my AW M5550 w/945PM chipset (to go from 533 to 667). Here is what I got:
BSEL 1 and 0 jumpered = no boot
BSEL 1 and 0 jumpered, BSEL 1 bent = no boot
Jumper between BSEL 1 & 0 removed, BSEL 1 bent = Boot @ 667 but multiplier locked at 6X

yep thats pretty much it, if pin modding works for the faster fsb. the multi is locked to the lowest one, so pin modding doesnt really pay off. i think it has to do with the way the newer laptop bios's work. Either that or the new bios is only with the mac books sporting intel hardware. i know they made a big deal about it when Apple started using intel parts...
Hey guys....
I am looking to get some extra minutes battery life out of my CPU so I want to pinmod again and drop the vcore on the processor
http://www.ocforums.com/attachment.php?attachmentid=58785&stc=1&d=1186770776
^ Based on that image, what pins do I connect to pinmod 1.0v. The stock is 1.250v but I am pretty confident it can do 1v stable. That should yield me another 15-30 minutes life for the CPU wattage drop, and another few minutes as the fan will be on less due to the temperature drop.
Would it just be a pin between VID5 and VID3 ??
And when it says FROM TOP VIEW OF PROCESSOR, that means looking at the core right? So the picture is showing bottom left corner, so in reality I reverse it and I will be pinning the bottom right, correct?

No change. The 1.063v is the speestep kicking in. It is 1.250v running at 1.5GHz and 1.063v when lowered to 6x333, or 1GHz.

Hello ps2cho,
Any VID(x) are "hardcoded" in cpu finalization process, due to every core unique "possibilites" or finalization factory test results.
Therefore no one cpu is 100% "identical" to another for instance from same "yonah family".
Accordingly your VID pinmod change is not reflected by CPU internal Voltage sensor - this still shows you (for example via CPU-Z)
only these default or "hardcoded" values (voltages) for respective VID(s).
Also proggies like RMClock or CrystalCPU allows you to change these "hardcoded" values only in manufacturer "pre-programmed" range.
So (X) values you can achieve only via pinmod.
So my hint is - your VID change will be "measurable" via thermal core sensors:
after your VID change(s) test idle / max cpu load temperatures...
- of course higher voltage (from datasheet table) = higher temperature,
lower voltage = lower temp...

let me back up here for minute to make sure you fully understand. the PLL controls the FSB, thats all it does. the NB has two different busses i needs to control the SDR buss and the QDR buss. one buss feeds the cpu from the NB and the other feeds the SB. there is no way that cutting a PLL trace to the NB is going to magiclly fix the multi lock problem when you pin mod the cpu.
second if you did look into what/how that pin mod worked for the guy it makes sense. how ever it is not because of some magic cut trace on the motherboard. the Intel X9000 is a extreme mobile cpu with a unlocked multi so it can be changed at will. in the right laptop or more correctly one with the right kind of setup in the bios, you could then change the multi of the cpu. since this cpu can change the multi, by using the pin mod he was then able to change from the normally locked 6x. the locked 6x is only going to happen on non-extreme cpus or so it seems. since you haven't provided much more then what i find a far fetched story. that a cut trace fixed the locked multi of a cpu, which by the way is controlled by the bios. which has nothing to do with the PLL(ie clock generator).
if he tells you he cut a trace on the motherboard and that unlocked the multi, then yes he is lying out his wazoo.
agree a "cut only" is bad ....info interesting and about x9000,
looks like have a T9500,T9300,T8300 or T8100 installed to test properly an then X9000.

the theory to disable the "trusted mode enable" sounds possible but there are alot of other variables that can affect whether it can be done or not.
Your going to have to check if you actually use the PCI2 signal first else this will be useless for you.
You also have to "good" soldering skills as you'll be working with surface mounted components, he got extremely lucky and just had to move resistor beside the pll to ground the pin, i'd practice a bit first before you try it out.
looking forward to where this is going.
