tat just proved ure current overclock is not stable yet and prime stable doesn't mean it's 3d stable....to define a total stable overclock, u need to pass all 3 prime95, memtest86+ and 3dmark2001...btw i found a program call SNM which can detects error for both cpu and mem faster than prime/sp2004 and memtest...it also stresses ure cpu more and the temp shoots higher and faster compared to prime...u can give it a try if u need something to stress the cpu and mem faster b4 u go for a 24hours stressing running prime.

try running sp2004 small fft test with priority 10 for 24hours to test ure cpu stability
run memtest86+ with test #5 for 8 hours for ure ram stability and running 2dmark2001 with real time runtime (go to ure windows task manager, click on the processes tab and sekect 3dmark2001.exe and right click, select priority and select real time)
if u can pass all the criterias above then u'll have a 99% stable overclock

anyway it's something i read over in ocforums and applies to only those that go for a totally stable overclock...you can actually consider ure setup stable if u can play games for hours long but fail prime as soon as it starts....everyone has their own defination of a stable overclock depending on their needs

p/s: u might wanna check ure gfx if it's overclocked since it's a problem occured during gaming

msi k7n2 delta 2 bo3 bios
bigwater cooling.

try and lower ure overclock and test using 3dmark
btw wat test did u ran on sp2004??

Ush, watercooling... no wonder. Maybe later i'll try out watercooling too 

try running 11x220 in memtest86+ with test #5 for 2-3 hours to see if ure mem is limiting you or not...if it's not then try upping ure vcore to 1.85 or 1.9 if u dare to try...if tat still doesn't work then i believe ure proc had reached its limit...u could try a slight bump on the vdd and vagp and see if it helps

ok, will tell u the results.

don't know how to use memtest. so with 200x11, i tested with sisofy sandra. got error. see attachment.

Does it pass Large in-place FFT?

the best way to quick-stress your cpu is by putting 64K min, 512K max, in-place FFT, each FFT run for 5mins.

64K fits the L1 cache (x2), 512K fits the L2 cache.

btw... i'll be soon joining the rank. just waiting for my DTR Athlon XP

increase ure vcore another notch

My new CPU, same as tone's stepping. Using KT333 , it primes fail at 12.5x166@1.4Vcore.

Tone, can yours prime stable on that vcore and speed? just wondering....

EDIT: It's stable now. Don't know why....lol

cubchai,

i would prefer CPU Burn-in tool for burn in. I only use SP2004/Prime95 for stability/stress testing
