I didn't try it myself with the v25 client, but I guess you do it like this:[QUOTE="undoc.txt"]The benchmarking code by default only times a subset of the large FFT sizes.
In prime.txt, set FullBench=1 to have the benchmarking code time all of the large FFT sizes.[/QUOTE] |

[QUOTE=henryzz;156676]pretty rubbish with two threads
i though all dual cores scaled better than than[/QUOTE]If you look at all the numbers, across most of the normally-used FFT sizes you'll see that 2-thread version runs at about 170% of the speed of the 1-thread version. The very-small FFT sizes (4K-10K) have zero performance change in 2-thread version. 40K-80K FFTs actually perform significantly worse in 2-threaded than single-threaded. But this isn't much to worry about... from 96K onwards it's pretty consistent, and 96K is tiny (used for M1648000 to M1966000, by default). See attachment for graph. |

Intel(R) Pentium(R) Dual CPU misled me why doesnt it say core 2 is it a misrecognized cpu[/QUOTE] Your's says that your CPU only has 4MB L2 Cache and not 2x 4MB or 8MB. But we know the truth. :) This CPU is about the same age as your Q6600 and I benchmarked it with DDR2-800 RAM running at 800MHz. I will try pushing the RAM more later but that was not what I was benchmarking this time. I just wanted to share with everyone the results of this CPU overclocked so everyone could see that a lower-end CPU with OK cooling still can get good results. When compared to other similarly clocked CPUs it did better than I expected but still the lower L2 hurts it. This is CPU has the potential to be a decent economy gamers CPU when overclocked. |
