I got the whole overclocking thing down today, and ive been noticing with CPU-z that my speed has been throttling as low as 2.8ghz. I have a AMD Phenom II X4 965 BE stock at 3.4ghz I have it overclocked to 3.8. When Im idle its fine. 3.8ghz the whole time. When Im in game it throttles all the time. I have everything that should be off turned off, cool n quiet, cpu spectrum ( i had it turned on and it did the same thing ) and C1E all off. I ran prime 95 for about 15 mins and temps are good about 50-51C highest peaked at 53C. I dont have the NB OC at all since everytime I tried to it just blue screened on startup. Any help would be really appreciated.

do not bump and lower your overclock even if the temp are good maybe you memory could not handle this overclock

does you motherboard have a onboard graphic chipset you could try or do you have another card for test to see if you still get blue screen also what are the other parts name and model in the system

since your board got 2 pci-e slot did you try the card in the second slot to see if there is bsod on start up also what is your psu try this to see if system report what cause the bsod http://www.resplendence.com/whocrashed seen you ogot 8 gig of memory i would try with one stick on the system at the time

It cant be the graphics card, my psu is a corsair gs700, and I seem to be having problems with it as I just found this out a little bit ago, as theres only 3.15v on the +5v rail.

Yeah im using hwmonitor right now and just noticed it right now that my 5v rail isnt getting enough volts. I have 5 fans 4 120mm and 1 200mm could that be the problem and if so should I buy like a 800-850 watt ?

Have you disabled AMD Cool 'n' Quiet in the BIOS?

Yes CnQ, c1e, and cpu spectrum, and I changed my windows power savings to high performance

HWMonitor may misread some voltages. Mine reads 8.18V on 12V rail. Yours probably also.

I only had a blue screen if I overclocked the NB, I raised the voltage on it, and it didnt blue screen, then after a couple mins it blue screened so I just set it back to 2000. I only blue screen when overclocking the NB though.
