Prime95 BS :(

[dug777]

i'll give it a shot come tuesday (just got two 3rd yr law exams on monday 2 pass 🙁( ) and i'll let u folks know the results.

I am running mem timings of 2,4,2,10 i think- thats the fastest i can run with my crappy generic hynix RAM...probably worth looking into then 😛

Cheers 🙂

P95 has recently pissed me off because the results for me are now different then they were before. At 211 x11 I had been running for over a year as it was tested P95 stable for a 24 hour period. Now, with temps lower then at that time due to a new CPU fan, I am not P95 stable anymore at the same speed and I have no idea why. The only things that have changed is SP1 became SP2, got new version of P95 to use and Radeon 9700 is not X800.

I get the hardware failure test now after about a minute. Maybe the X800 cant handle the high FSB?

re: your above question...its all not that easy becasue a CPU is a complex thing..sorry to sound like a dumba$$ knowitall 🙂 But you never know WHEN and how your CPU with WHICH application/game calculates right. Some calculations (eg. FFP operations) may put more load on the CPU than other instructions, therefore people use Prime which uses the CPU to its maximum to test stability.

ALso..the "failed" overclock may not bew visible to YOU...a failed OC does not necessarely mean your comp crashes - often it just "calculates wong"...eg. prime/seti...etc...generate wrong results.

Same btw applies to graphic card overclocking - the card itself seems like it renders ok.....but the shader code (eg. if FFP shader code is used) fails to caclulate right which can lead to more or less apparent "errors", some visible, some not, some only after someone told you so and often only for certain shadfer-routines.

You decide whether you want to gamble....but in my opinion it is just NOT worth it. If i spend a grand or so on a new PC then i expect at least it works right in every aspect..just to avoid ANY future problems....i dont think that a 0.5 percent performance gain legitimates a NON 100% working CPU...and, as you see in recent titles (eg. doom3)...these are the titles where, all of a sudden, people realize they need to clock down....because these titles demand more than other titles which dont use the CPU/GPU to its fullest.

Edit: its FPP (floating point precision, AFAIK...not FFP..sorry..long day 🙂

X800 exchanged for 9700 ? Could be PSU....more power is drawn and the PSU is on its limit -> less stable rails -> less overclock

I am starting to wonder also

I have a sparkle 400W with the 5V rail modded but even with that done what I have now that I didnt have when I built this system is the X800 which I have flashed to XT PE speed, and also a Tornado 90 on the CPU. Maybe that has taken this PS about as far as it can go.

Whats funny is with the P95 thing I would not have even checked. I assumed that if it was stable before it would be stable now, but with the addition of the Tornado and my CPU temps at load dropping to around 47c from close to 60c I thought I would see if I could go higher on the FSB with the Athlon 2500+

I was playing around with FSB up to 230 and the 10.5, and 11.5 multi and they all would fail on P95. Then finally I tried it at my default speed while cursing the whole time that I had to even do this and it failed after a minute then the 2nd time after 17 minutes. Im pissed LOL
