Opteron 146 CABYE 0540FP()W ()=A,B,W own!

[Shimmishim]

I have had the privilege of testing a bunch of opterons these last 2 weeks.

I have 2 146's 0540FP()W.

1st one.
CABYE 0540FPMW

6+ hours prime small FFT stable (Corporate Thug is now the owner of this chip)



2nd one.
CABYE 0540FPAW

2+ hours prime small FFT testing at the moment



I have yet to see a CABYE 0540FP()W () = A,B,W chip not do more than 2.9 ghz.

I was hoping for a FPBW as these seem to consistently get to 3 ghz with less than or around 1.5 volts.



As for those that use large FFT prime for stability, I have stopped using it as I have found that chips can run large fft prime at 3.0 ghz (6+ hours) but will error in small fft in less than 4 seconds. That is the reasoning behind why I use small FFT.

hmmm, anxiously waiting to get it in my hands! precious opteron

btw, great work for testing so many chips. :thumbsup:

just to clarify: small FFTs are better for stress testing than mixed or large?

Small is best for the CPU stressing

thanks. good to have pjay's support.

someone said i was dumb for using small fft and not large.

well i've used both now and large fft is not reliable for testing pure cpu speed stability.

small fft's is for isolating the cpu

large ffts is for isolating the ram
