The more I overclock my I7 the longer it takes to complete a WU, but overclocking still improves my Boinc and 3DMark06 benchmark scores. Is this normal? I think it might be some issue with this new ram I got. I have never had any wu errors from overclocking even though the times increase.

Which project are you working?
Did you recently switch HT to be on? If you clocking it really high some mothernoards will step the cpu multi down as it feels necessary to make sure the cpu does not drawn so much power as to hurt itself. If you open RealTemp and watch the multiplier in the top right you will see it switch around. |

Hummm, it no make sense for me !
---------------------------------------- For sure the overclocking must be speed up your WU's processing not the contrary... check all your system and share with us what project are you processing under the overclocking. Are you running under Linux, Windows. Mac ? What is the complete specification/details of your config ? (include your cooling system and power source characteristics). And about your memory faults historic ? Is a dedicated machine running WCG ? What is the BOINC agent release installed ?

I only crunch HCC. I built this system myself and this started happening after I upgraded the ram from a generic kind to some mushkin ddr3 800mhz. With the generic RAM, overclocking improved WU times.
I am using win 7 with i7 920, Gigabyte ud4p board, enzotech xtreme fan cooling, 9800gt. But like I said I think there's something wrong with the memory setttings because I can't overclock as high with the new RAM either. |

Would you please look in the TaskManager or better get MS Sysinternals Process Explorer and look at the different Performance components, particular Kernel Time, Page Faults, soft and Delta. Your timings might be way off. HCC on my W7-64 Q6600 stock performs exemplary. I recently tested this in different concurrency sets, 1, 3, and 4 concurrent and PF/PFDelta/Kerneltime was Low.
----------------------------------------Also, look on the Result Status page and post a list of your last 15 valid results [Filter, click Time Returned], then click on a few WU names to see what your wingmen are doing. HCC is very integer intense and should race on 64 bits compared to 32 bit, the research app at WCG having most benefit of 64 bit platforms without being specifically being compiled for it.

I think this happens to any WU.. not just HCC - that's just what I normally crunch. The timings of my memory are what they are suppose to to be. This is while BOINC is running:

Something isn't right, but I'm not a hardware tweaker to be able to tell you where to look.
----------------------------------------Here's my HCC last output, just a Q6600, 2.4Ghz stock, 533 speed ram (it's actually 666, but the mobo stops me from changing that). Have no Delta at all and ~200k PF per job. W7-64 / 64 bit 6.10 client.

Yeah something doesn't seem right, I think it should be able to do them in under 5 hours. I will try another source... thanks

You have DDR3 1600 Mhz RAM. You run at 1410 Mhz which is ok. I see that you have set the Latency at 6, which is an excellent value for DDR3. Is your original memory spec at that value? Seems agressive timing.
