Stats in my sig.

Proc Voltage 1.75

Mem Voltage 2.7

Runs prime for 6 Hours then I get an error, something about expecting less then .4 while rounding but getting a .499999~

For a while i was getting the same error almost instantly from prime, but then i raised the vdimm to 2.7 and now i still can't play games but prime runs for 6hours give or take.

BTW My bios is v2.2

You got the very exact trouble that I got with my Abit NF7-S. Except I had to run much higher voltages and could never really run at 200 FSB at all.

Are you running the blend torture test? That used to kill my computer in 4 minutes maximum.

Just curious, whats the best setting for prime 95 to test?
 
yeah im running the one that tests a little bit of everything

it runs very well at stock but i still can't play games with it at 11x200.

I need help!!!
 
I really don't know what to say except update your bios or something along that lines because me and a lot of my friends all run our Bartons and NF7's at 210+ x 11
 
Try moving your ram to 2-2-2-11 and see if that makes a diff for games. If not, try relaxing it ever more to like 2.5-3-3-11 (just to make sure its not the ram giving you grief).

If you have the same symptoms after that, I would start looking closer at your video card since Prime95 does not tax that but games do.

If your chip can handle 6 hours of prime, it should handle some gaming.
 
You may just have a crappy XP2500 like me. Runs at 200x11 1.824v but will crash to desktop when gaming after an hour :(. Raising the vcore fixes the problem but I don't want to go any higher than I'm already at.
 
Games seem to run alright at 2-2-2-11 but I haven't seen any improvement in 3Dmark2001....im only getting 7900...I know thats rediculously low...and im hoping its only because of my video card.

Prime still crashes after a minute or so, but halo and unreal seem to work alright. im idleing at about 43ish. and my vdimm is up to 2.8 while my vcore is still 1.75. Im beginning to think that my chip really is crap. but i'll give it a little more time...i do have a 3year warrenty.

For those of you who do have their 2500's at 11x200 what are you settings at? ie voltages/temperature.
 
Turn up the voltage a little more on the CPU.

It seemed like my 2500+ wasn't as stable as everyone elses I read on the forums (they would do 3200+ speeds at stock voltage). Later I just chalked it up to my doing a more thourough job testing stability. Mine will do 3200+ speeds at stock, and even game, but with occasional errors. But will not even run prime for a minute at anything less than 1.75

I voltmodded my Asus and now run at 2.0 volts, I am just shy of 2400Mhz. Soon I will remove the resister I added to the line so I can max out volts and once the nothbridge block arrives I will add the other volt mod.
 
Maybe you just got a bad chip but that's highly unlikely. Up Vdimm to like 2.8V or 2.9V but then again I doubt it's your ram :(
 
I'm running an Abit NF-7 with a Barton 2500+.

I have Samsung PC2700, but I run mine at 11x200. The VCore is at 1.8 and DDR is at 2.8, so its a lot of voltage, but it runs pretty stable, on all my games at least.

Temps are:

48 CPU and 34 Case (Idle)
50 CPU and 36 Case (max load)

So my suggestion is also to turn up the power, but you will probably feel the heat.
 
I have the same cpu, m/b and bios revision. I can run 11x200 at a Vcore of 1.55V. I run my memory in turbo mode at 2.80V. 11x210 @ 1.70V and same memory voltage.

First, your voltage is most likely too low.
I have a 2500@2.3GHz under the exact same setup at 1.95V
45C Load.

Second, if you RMA that chip because it doesn't overclock as much as you want, you are filthy scum and should be hung from the nearest highway overpass with two bullets in your brain.
 
Did I just get lucky with my chip and board cause I mean It's rather hot but still....

215 x 11 @ 1.85V - 48c 100% Load

is that normal?
 
Try playing with the mulitpliers and frontside bus, the multiplier is the likely culprit with XP cpu instability. You just might find your system stable at 11.5 x 195 or 10.5 x 210 (a lot of XP cpu's hate to be set at certain multi's believe it or not, believe me, i've had 7 of them and read extensively about it).

Set your vcore at 1.8v to test. If everything is stable after a few reboots then try lowering vcore and test again (to try lowering temps)
