Recently I upgraded my old platform with q9650 from q6600 which use to work on 3.15ghz 3hr prime95 without any problems. Before I bought q9650 I did research and I found that these guys got 3.7ghz with q9650 and p5ql pro motherboard which is not great overclocker but they got 3.7ghz

So I tried these setups, bios won't even boot, neither on 3.6ghz, on 3.4ghz system crash while booting, on 3.33ghz system crash after 10 sec of prime, beside that there is something wierd with temperatures, c0 minimal temp is 42*C amd c2 41*C, no metter what they won't go under that only over, while c1 and c3 act normal where temp varies from 27*C to 36*C idle, cooler is TT Contac 30, Ram 2x2gb OCZ 800mhz not sure silver or platinum, and 2gb gold also 800mhz, psu LC Power600W, so I am not sure what is wrong, I assume it's bios, maybe I should clean CMOS to restart bios vrsion to fabric or there is something wrong with cpu?

No, I mean the actual CPU. The base frequency of a Q9660 is 2.8 GHz. you are only GUARANTEED 2.8 GHz. some chips can overclock an impressive 32% (+900 MHz from 2.8 to 3,7 GHz). Most won't get that far, even your Q6600 which could jump from 2.66 to 3.15 GHz (+490 MHz) was only an 18% improvement.

Not every chip will get those kinds of massive gains. Most will be far more modest. The difference is completely unpredictable and is affected literally by single nanometer or smaller differences in production conditions, both between batches and even within the SAME batch of chips

Rather than jumping all the way up to a 3.7 GHz, start at the bottom and work your way up.

Maybe I should sell this one and try to find another q9650 or q9550? btw you maid quite mistakes its q9650 not q9660 ana it is 3ghz stock, and q6600 is 2.4ghz and i made 3.15ghz which is 750mhz(30%) jump which is quite nice jump for this mobo while I can't do 10% with this proc.
Thank you for help I got few same answers about cpu being issue, but I just couldn't belive that it could be this stupid with 775lga procesors.
