cpu speed question

[tim]

I've not used boinc before, I installed and chose enigma, it wants an email and password. I pm'ed Helix through the free-dc pm function to see if he wants to share that info.

The hardware monitors both show the memory as ddr3 1600. It's weird that the cpu is running on 40 watts but showing full frequency. It could be a bug in the hardware monitoring programs that don't read Intel chip temps right, but the i5 2400 I have does show 80+ watts with the same programs.

I would run some benchmarks on it and compare it to others to get a feel for the system. Can you post a link to the system you purchased? Also run the SOB benchmark and post the numbers.

The box is http://www.newegg.com/Product/Produc...9SIA24G2HZ2404 Mine is the only review. I'm not sure what you mean by Sob benchmark. Here's what three boxes running Sob are doing. Top one is the system in question.

The SOB client(mprime.exe) has a benchmark mode built into it. It runs different numbers of threads and different FFT sizes. That is what I used to get the data from my systems to compare the actual performance. Different work downloaded has different FFT sizes and can affect the time reported.

Thanks so much for your help on this. I have a lot to learn.
Okay, here's the link to the page of previous benchmarks for this cpu: http://www.mersenne.org/report_bench...ic_cpu=4377447

and here's the mprime benchmark output from mine. I'm not sure how to interpret it. Do I compare the "best time for" section to the benchmarks, or the "Timings for " section, looking at 4 cpus running 4 workers?
And for what's it's worth, under linux, the screen output for normal work for FFT 2M, pass1 256, pass2 8K (all 4 cores the same) was from 31 to 39 ms/iteration.

Okay, more data. I've downloaded Intel Extreme Tuning Utility, and it shows TurboBoost is disabled. But it's enabled in the bios, and Win7 power setting is on High Performance. So I don't get it. And yes, it is enabled in the bios. Any ideas?

Another edit: I reset the bios to factory settings, and under Intel XTU, it now shows TurboBoost is enabled. No difference in performance, though. I did the prime95 torture test modes, the highest heat mode got the watts up to 63 and the heat to 159, the highest power consumption mode was 44 watts and 129 F, the same as normal operation.

The system could be throttling way too soon. Check the heatsink and paste. Possibly upgrade the cooling of the CPU and case. Try running cpu-z while the system is loaded and monitor the top speed of the processor.
