Can someone give me a simple step by step guide on how to overclock my processor? I have never done this before and the tinkerer in me wants to try it. I've read this forum and other sites but it seems each one gives a little different story, maybe because there are different goals in mind. I just want to overclock to, say, 4.0 ghz or 4.2 ghz and see how it goes. Some people say to just leave everything as is except the mulitplier and everythings's good. Here are my specs:
Mobo: GA-Z68X-UD3H-B3
Processor: Core i7 2600K
Cooler: Scythe Mugen CPU cooler
Memory: Corsair Vengeance DDR3 1600 mhz (16GB)
Graphics: Sapphire AMD Radeon 6850
Thanks in advance for your consideration.
I'm very new around here, but this is my second Hackintosh. Thought I should share my experience:
I have the exact same MB/CPU/RAM combo. My only differentiation is the Gigabyte GV-R6870C Video Card. I have been reading EVERY post on this site and InsanelyMac inregards to OCing, and have beaten my head against the wall for three days now. The really infuriating thing is how <i>easy</i> everyone says SB overclocking is! Finally got it to work, here are my findings:
BIOS: U1h UEFI
OS: Mountain Lion, EasyBeast, SMBios: iMac12,2
Baseline GB 32-bit: 10500
Step 1: Increase Multiplier to 38, Increase Turbo Multipliers to 42,42,41,41, Increase turbo voltage to 120.
GB After:No change
HWMonitor: 16x1000mHz idle, 34x1000mHz load
Step 2: Increase vCORE to 1.30v
GB After:No change
HWMonitor: 16x1000mHz idle, 34x1000mHz load
Step 3: Install MacMan's SSDT for i5/i7 Overclock from MultiBeast. Repair, reboot
GB After:No change
HWMonitor: 16x1000mHz idle, 34x1000mHz load
Step 4: Modify Chameleon boot.plist to GenerateCStates=Yes and GeneratePStates=Yes, Repair, Reboot
GB After:No change
HWMonitor: 16x1000mHz idle, 34x1000mHz load
Step 5: Remove NullCPUPowerManagement kext, Repair, Reboot
GB After:5400!!!
HWMonitor: 16x1000mHz idle, 16x1000mHz load
Step 6: Undo step 3, idiot. (using kextbeast)
GB After:10500
HWMonitor: 16x1000mHz idle, 34x1000mHz load
Step 7: Disable EIST in BIOS, disable C3/C6 in BIOS
GB After:13000
HWMonitor: 16x1000mHz idle, 41x1000mHz load
Success!!!!! Only issue I can see is that I toggle only between 16x/41x, which I don't mind. Temperatures stay under 70°C while seven instances of
running in Terminal and the CPU at 750% load for one hour. Calling it a win. I may try to up the turbo multipliers (one increment at a time) to see if I can go a little further. Now if only I could figure out why my write speeds on my OCZ Vertex3 SSD are peaking at 150MB/s.....
