I have just built a pc for someone who will use it for gaming, spec as follows:- Intel QX 9770 extreme Scythe ninja mini HSF ASUS Extreme rampage mobo 4GB DDR3 OCZ Reaper memory Antec 900 case 1100W PSU Sapphire HD4870 X2 graphics WD veloceraptor 300GB Windows Vista home premium 64 Performance is as you might expect, pretty damn good, Vista gives it a score of 5.7 and PCmark 06 gives me about 18600. The question I would like to ask is about overclocking the processor, the person I have built it for has asked me if I can do it for them. Temperatures at stock speed are about 41 C at idle and at about 63 C when running prime95. If I overclock about 10%, ie to 3500 the temperature when running prime95 shoots up to about 93 C. I checked on various sites and several people seem to be able to regularly clock to over 4000, but having said that information often seems to be confusing,on one site Intel were stating that this processor should not be run air cooled, another suggested that this processor is like the old P4 and gets very hot if overclocked, yet others don't seem to have problems with overclocking. You may ask why anyone would want to overclock a £1000 processor, I can't answer that, you know what gamers are like. Has anyone any suggestions as to what I can try to keep temperatures down without resorting to liquid cooling or are you of the same opinion as me and leave it at stock speed which is more than enough to play her games.
