I want to overclock my cpu.
AMD Phenom II x4 965 BE 3.4 Ghz
Zalman CNPS11X Performa (1 fan) cpu cooler
4 GB Kingston 1600 MHZ
Thermaltake Toughpower XT 775W
Zalman Z7 case
I want to know what is the max overclock that i can do.
If i need an additional fan to CPU cooler which fan is fits to my CPU cooler?
How to overclock my cpu?
i would like to know some additional information which can be assumed.
My X6 1090T tops out at 4.2ghz but I have to pump alot of voltage at it to stay stable. Once I stated OCing my Northbridge and Ram I had to drop the cpu to 4.0ghz to stay stable. By doing this I was able to drop my CPU vcore quite a bit and keep temps in check for 24/7 use under heavy loads on hot days. I now idle at 23 degrees celcius, and under load hit about 50 degrees. The load being a loop of 3dmark 06 cpu test in a loop for about 30 mins. During gaming I never see it go above 46 degrees.
Overall anything above 4.0ghz is not really needed IMO since the voltage to get there won't really cause any huge gains in anything performance wise. Benchmark scores will be slightly higher but FPS in games will only increase a few frames at best, and thats only in CPU intensive games.
You'll get slightly better results doing it manually, Sincreator linked a decent guide and theres one here on Toms as well, http://www.tomshardware.co.uk/forum/274820-11-black-edi...
4GHz is the most reasonable target on deneb chips but as mlcaouette said, some lucky folks get higher (usually with water)
I had that chip for a year and I ran at a stable 3.8ghz, no voltage increases on stock cooling without ever going above 55c at full load in Prime95. My case has exceptional push/pull fans though so that helped alot. With your cooler 3.8ghz is a reasonable OC and it will be fast. It's a good CPU I loved it!
Its a lottery at one point or another, my 975 boots windows and plays crysis at 4.6GHz,won't pass P95 or ibt though, and some won't shift from stock, its down to natural variances in the silicon itself and can't be changed
