I just got my new 2500xp mobile..
The highest settings i can get for it are
Multiplier = 12.5
FSB = 180
Voltage = 1.6
Load temp 46 while priming
________________________________
If i go any higher Prime95 fails within 5 min..what should i do to get more MHZ outta my new "overclocking gem"

[Yuriman]

It probably likes more vcore. Set the vcore to 1.75(or more) and try out 200x11. If its stable, try 200x11.5. Then 200x12. You get the picture.

[dead_man311]

it will need more Vcore to go higher

[Tatuya]

Whaaaaaaaaaaaaa...?? You're at 1.6 on a mobile and it wont go higher? I thought some people have OCed their's to 11*200=2200 MHz with stock voltage and lower, bad chip or what. I would like to hear a response of some sort to this issue, very odd it is...

[prankstar008]

I had the vcore at 1.65 and it would still fail prime

Lower the multi.

[prankstar008]

lol i just raised the multi to 13 and lowered teh FSB to 176....and vcore to 1.625.....been priming for a while w/o errors....i know you get mroe gain from the fsb...so ill lower the multi to 12 and bring the fsb up and see what happens

[The Coolest]

What memory do you have? And are you running it Sync or Async with FSB?

[prankstar008]

The mem is sync...i think it might be the problem because i just lowered the multi to 12 and raised the FSB to 190 and it failed prime before you can say corshair xmx platinum

[maxima88]

Increase your Vcore and VDIMM.

[prankstar008]

Maybe i just got a bad CPU cause i dropped the FSB back down to 176 and raised the multi to 13.5 @1.65 vcore and windows locked up before it finished booting...ill try raising the vdimm too...thanks for the help

[maxima88]

Don't be afraid to increase your voltage little by little. You've got a great HSF there to control your cpu temp.

[prankstar008]

yea its 43 under load right now....while i fold for team 32
i have to go to a mid afternoon LAN right now so ill update this later tonight/tomorow

[prankstar008]

ok..i upped the vdimm to 2.7 and then upped the FSB back to 190....the comp didnt even post....im keeping th FSB at 180 and ill try to raise the multi some more

[itshondo]

try 210 x 12 at 1.85 to 1.9v vcore-

2.9v vdimm if you have good cas 2 bh-5 mem-

mem timings 7-2-2-2 if cas 2.0

cpu interface enabled

[prankstar008]

that sounds very agressive....ill try it

[c627627]

This is post number 17 of this thread and he still hasn't told us what RAM he's using. You can't go higher with average PC2700 if that's what you got. Put the RAM brand in your sig.

its corshair xms pc3200 srry...im really scared 9about to puke) cause i tried these timings try 210 x 12 at 1.85 to 1.9v vcore-

2.9v vdimm if you have good cas 2 bh-5 mem-

mem timings 7-2-2-2 if cas 2.0

and even after clearing the CMOS i get one long beep folowed by 9 short beeps which is a ROM error...fix it PLEASE

[prankstar008]

lol i feel so stupid....i went to clear the CMOS again and realized that i had only knocked out the power cord from my 9800pro...sorry i feel so stupid....anyways lets just start over....
Hi, my chip isnt overclocking well...i have 512MB of corshair xms platinum PC3200 (DDR400)...and the rest is in my sig...right now the highest i can get is 180FSB by 13 multi at 1.625 vcore....memtimings are 6-2-2-2.5 i believe )whatever TURBO on a NF7-S is)Thanks for puttin up with a major nub.

[snvpa]

make sure you turn power off or unplug from the wall when you clear cmos. If that doesn't work you can remove the battery. Still nothing try holding down insert as you boot up. If none of these options works you might have borked the bios. Not much you can do in that case unless you get a new bios chip from abit or can borrow a friends to hot swap with.

[JerMe]

Maybe I ran through the thread too quickly, but you gotta establish a baseline first.

Run Prime95 on that chip at stock speed and voltage for 24 hours to rule out the possibility of a bad chip.

If it fails, run Memtest86 to rule out the possibility of bad memory.
If that fails, relax the mem timings and try again.

Let us know.

[snvpa]

Glad to see ys got that bios problem fixed. Rigth now your running in excess of 2300 mhz with only 1.6v, the nf-7s undervolts quite badly. Your gonna need to raise that v core. Don't be afraid to go at least to 1.85v y. our cooling can handle it. You know 180 at those timings is stable so just up the multi for now. try 13.5 then 14 ect... you should top out somewhere between 2.5-2.6 ghz. You are gonna have to raise the voltage so just do it. I have yet to see a 2.4+ oc at what is really 1.6v or so. If you freeze your cpu then that might be another story but I don;t see it happening on air.

[itshondo]

alright bro, you gotta raise that vore if you wanna push it- I've been at1.93v for a month now, and you have a better heatsink than me-

Those timings 6-2-2-2 are ok, but the N-Force 2 chipset likes 7-2-2-2 or 11-2-2-2 better- I'm using 7-2-2-2 'cause it runs 2c cooler -

i.9v vcore shouldn't hurt your chip- give it a shot and watch your temps.

[prankstar008]

When I put it at 1.85 is when it gave me the out of spec tone and I had to clear CMOS....I also had the VDIMMS at 2.9 when that happened so that could have been it...i will try raising the vcore to like 18 and making the multi 13.5....I also dont know what I did...but my temps have dropped 4 deg! Thanks so much..OH and BTW I started running folding@home on this new box for team 32

[Quailane]

I think your psu is holding you back.

[prankstar008]

I think your psu is holding you back.
What would make you think that..420W...It powers the folowing
2 optical drives
1 7200RPM HDD
1 Saphire 9800PRO
1 FDD
1 92mm HSF
1 NF7-S w/ the cpu and ram in my sig
4 80mm case fans
1 Cold Cathode
1 stock chipset fan
I must have 10 unused molex connectors ziptied somewhere in my case...
And I reccomend this PSU (if it is not really a problem wattae wise for me) The rails vary .03 from spec and its heavy...Also it was only $35

Enlight is a good brand BUT--I would want 450 watts on that rig minimum.

Just 'cause the rails don't difer doesn't mean that it's a good PSU. Put everything under load--CPU, VPU and drives, and THEN take your voltage readings.

i.e. folding@home or 3dmark time.

[prankstar008]

What exactaly is the "default specs" for my RAM, I'm begining to think its defective....the website says 200FSB is no problem....also..I set it to 200 FSB 13 multi and raised the vcore to 1.85 and i got out of spec voltage error..ill go run 3d mark and check the rails

[Captain Newbie]

Your Abit board is doing the best it can to prevent you from frying something. That's what "Out of spec" means.

There's probably a switch in the bios that will allow full manual control. I haven't played around much with my NF7 and so I can't tell you where it is...

I have mostly every setting on User Define....or "allow overclocked parameters"

[prankstar008]

vcore is runnin at 1.7 right now....but multi is still 13 and fsb is 176

dude i have like the same number of components + 1 extra HDD in my rig but it would fail to power up 2 drives with a 450W psu hence i went with a 500W psu and had no problems since. of course it shouldn't be generic one either. another paradox is that not all ram that's pc3200 or whatever flavor of ram will run stably at it's default speed and timings. yes i know it's screwed up but true with some not all brands and models of ram. my ram was not stable at all at 400 mhz so i had to underclock it a bit. also when you overclock you should adjust the vcore in small increments and test for stability with each setting. if 1.7 doesn't work, try 1.75 next etc. try 11 x 200 @ 1.7, 1.75, 1.8. if one of those work, go up again with 12 x 200 @ the last stable voltage you used. you'll need to also play with your memory timings as you do this to search for stability.

The jury seems to have reached a verdict. More power!

200x13...man 2.6ghz...okay first of all you should set one option at a time in the bios, not TOTALLY necessary but it will help you from getting bios corruption...IE: change multiplier down to ELEVEN (11), exit save, then change fsb to 200, for a more reasonable speed of 2.2ghz, exit and save, then boost ur vcore up to 1.85v, exit-save, and now you can try to raise multiplier again by .5 increments. TRY that instead of just randomly putting a multiplier and a high FSB, most likely your chip is failing at 2.6ghz with only 1.85volts. Good luck tho and not all chips are created equal, so you gotta figure out your chips max capabilities, but do it SLOWLY, checking for stability and temperatures.
