hello all i am new here found this site looking for help on overclocking my gaming pc to the best it can go within its limits.

my set up as follows

Samsung SM2433BW 24" Widescreen LCD Monitor

corsair 800d

corsair h50

Intel Core i7 860 2.80Ghz (Nehalem) (Socket LGA1156)

Asus Maximus III Formula Intel P55 (Socket 1156) DDR3 Motherboard


XFX ATI Radeon HD 5850 1024MB GDDR5 PCI-Express Graphics Card x2

Corsair HX 850W ATX Modular SLI Compliant Power Supply

Samsung SpinPoint F3 1tb SATA-II 32MB Cache x1

Crucial M225 64GB 2.5" SATA-II Solid State Hard Drive x1

LG GH22NS40 22x DVD±RW SATA Dual Layer ReWriter x1

G.Skill Ripjaw 4GB (2x2GB) DDR3 PC3-16000C9 2000MHz Dual Channel

120mm Enermax UCMA12 Magma TWISTER Fan (M.B.T.) Batwing Blades 1.5k RPM x5

140mm Xigmatek XLF-F1453 LED 1000 RPM and 63.6 CFM and 16 dBA x2

been running on stock for the last two weeks or so playing arma 2 fairly well without any problems all on full settings,so i know it can run ok but as always its nice to see how far it will go before it either gets unstable or it hits the temps to high.

i have read and read so many ideas of oc'ing this chip its all gone over my head and to be honest i rather have that personal touch of a real person helping me,i understand that two chips are never the same for volts ect but a starting block would be a great help that i would only need to increase or decrease the volts if needed.

sorry if this is a long post just thought i try and explain it all

cheers and looked forward to your help.

I have the same board chip and ram, I'm running 4.0GHz stable atm
I started off with volts a little high comming from 775 the bios was a little different after a few hours of tweaking I had 4.0GHz dialed in. With some very helpful advice from Alien432 I got my volts lowered alot and of course reduced temps, why this will not work right out of the box, this should get you to 4.0 very fast, vcore should be your only adjustment...
