Ran mine for about 2 hours, no problems. Speed rated at about 38 GFlops. Temperatures max'ed out at 78 thru 81 ..... cooling is the standard heatsink that came with the processor plus large diameter/flow case fans.
Processor: Intel(R) Core(TM) i7 CPU 920 ( Bloomfield ) @ 2.67GHz

Revision : D0
Clock Speed: 2.67 GHz
Bus Speed : 2405.4 MHz
Mobo : ASUS P6T SE ( Intel chipset + AMI BIOS )
Active Physical Cores: 8
Core Voltage : 1.176 V
Total System Memory: 6135 MB ( Corsair DDR3 )

Cheers, Mike.
I have made this letter longer than usual because I lack the time to make it shorter ...
... and my other CPU is a Ryzen 5950X :-) Blaise Pascal
Nice undervolt for efficiency.
I can appreciate finding the max BCLK at any given vCore.
I have only been doing this for a year and fairly recently brought up my second i7. I *think* I have found the max for both, the min for my old C0 and will wait until temps start to warm up again to find the middle ground on both.

I hadn't been attempting any optimisations, what you see is basically what I got 'out of the box'. It'd likely be typical figures for a similiar un-tweaked systems then. I've seen figures about 80 GFlops quoted elsewhere for i7 920 boxes.

Hi, probably measured in SSE3. 'Normally' the i7 920, is about 2.5xx GFLOPS per core. But 8 times= 20 GFLOPS.
Brings me to the question, are there "optimized" applicarions? .Like SS(S)E3x; SSE4.1/4.2., for CPU.
Maybe not even very usefull, since the CUDA came. Can (CAL / Brook)ATI, also be used?

There are two optimized versions of the S5R6 app for SSE and SSE2 respectively. ATI GPUs are not yet supported. Most likely ATI GPU support will arrive as an OpenCL app rather than ATI-proprietary stuff.
