Processor GFlops Compilation

Table Updated.

 

average GFlops = all runs added together \ divided by number of runs

so your twilyth your avg gflops would workout to be 138.8102 \ 5 = 27.76204

 

I'm sad I can run folding@Home for days and play games and what not with out a single crash but I can't do more than one run of this burn in test.

1.48 votls @ 4095mhz. Any tips to make it stable? Temps 43C Idle.

 

It's not really stable unless you can run at full load for at the very least, several hours, w/o any problems. You'll probably need to tweak a few of the parameters that are normally involved in getting a good overclock beyond where they are now - if it's possible to do safely. If not, you'll have to settle for a slower speed.

I think that question is worthy of it's own thread though and I don't think the OP would want this thread to go off on that kind of tangent. I'm just guessing but it is pretty narrowly focused, and seriously, I think you would get a good response.

just some undervolting stabilty testing, but might as well add this to the list too.

Ok Understood guys, however I think its temp issue for me. No matter what voltage I give it as soon as it hits 63C it BSODs. So bottom line is I need a better cooling solution.

 

Did mine on MAX settings .

trickson Intel Q9650 @ 4.0GHz 47.3793 64-bit

I see mine there but you have the wrong OS listed and I updated some as well .

 

Table updated.

YAY Finally got it stable! And its faster than before!

AphexDreamer | AMD | Amd Phenom II 965 @ 4047Mhz | 130.71 | 64bit | 4 threads Air 1.496 Volts.





I'm so happy

AVG Came out to be 52.444 GFlops

nice thread, i will upload my results soon

 

i will try it

 

I'll try it.

Wow some interesting results for you Mussels:

newtekie1 | Intel | Core i7 875K@3.6GHz | 043.9826 | 12.2174 | 64-bit| Hyperthreading ON and 8 Threads
newtekie1 | Intel | Core i7 875K@3.6GHz | 048.9807 | 13.6057 | 64-bit| Hyperthreading ON and 4 Threads
newtekie1 | Intel | Core i7 875K@3.6GHz | 049.3956 | 13.7210 | 64-bit| Hyperthreading OFF and 8 Threads
newtekie1 | Intel | Core i7 875K@3.6GHz | 050.6025 | 14.0562 | 64-bit| Hyperthreading OFF and 4 Threads

 

You mean 50.60 / 4 = 12.65

Still faster per core, but your extra 2 physical cores pushes you ahead of me.

And hyperthreading really seems to throw this application for a loop. Even with HT off and 8 threads, the Windows scheduler seems to do a better job switching between the threads then Hyperthreading does.

 

AFAIK that's not how it works. One core has 2 threads when HT is on, it's still one core but by having 2 threads while one thread is not working the execution units 100% it leaves some room for the other thread to execute. If you were to run linpack with only one thread on core 1 say, the result would probably be very close if you did the same on just using the second thread on core 1. Problem is with linpack running on one thread it will already saturates the core leaving not much in the way of spare execution cycles so using 2 threads on the same core will likely result in ~half the execution speed for each thread wrt using just one thread on one core.

Something else you might find surprising is the core temperature differential when running linpack on just one core.

 

I redid mine this time normal setting and with windows 7 64 bit .

trickson Intel Q9650 @ 4.0GHz 53.3787 13.34 64-bit

 

The one you are using that scored 50.60 is 4 cores and 4 threads. With 4 cores and 8 threads I got 49.39.

Very nice score on that Q9650 Trickson! Amazing what 775 is still capable of
