i have been trying to run prime95 and monitor using realtemp on my e3-1230v2. the rated frequency should be 3.3Ghz and turbo up to 3.7Ghz. during the prime95 blend test, i noticed that the cpu is only stressed until 2.9Ghz.

any suggestions or comments on this? or is there a better cpu stress test program for xeon processors?

i have tried running the intel burn test, still the maxed core freq is 2.9GHz..

then i also found out that instead of 4 cores, hwinfo64 only detected 2 cores on my cpu:


the bios setting

thanks lucidlts for always helping with my questions, but no i already set to boot up as 4 cores

i have tried but not able to change. probably due to a locked cpu?

This is the CPUZ for current mobo:

This was CPUZ for my old mobo:

I have just flashed a new BIOS but still no change. will try to reseat the CPU as soon as possible. but could this be the problem? if CPU is seated wrongly should not be able to start at all vert

does flashing a new bios have same effect of resetting bios? might as well try all together and hope for the best

by the way, all sifus no need sleep at night ke?

i got worried because running Intel Burn Test @ Very High and Prime95 @ Blend Test only got me to 2.9Ghz max. and after i check using CPU-Z it shows only 2cores/4threads.

i dont mind if it achieves 3.5Ghz or 3.7Ghz after TB, but 2.9Ghz on 100% load?! its kinda freakish

well, i just discovered the solution though. turns out the msconfig thing should be left unchecked, and voila, my cores returned!!


last time i set it at 4 and somehow the option for 4,5,7,8 got removed. after unchecked it and restarted, the option up to processors returned.
