Help OC 4670k

post #1 of 7
Thread Starter 
good people. I could already do a small OC my 4670k to x42, the issue is that it is a x42 in the desktop .. I would like to lower the frequency to x38 when doing nothing would have to change the package C?

I have a motherboard msi max AC mpower

Do you mean it's running at 42x all the time....? If so go to control panel~power options~you will see to the right where it says ''select a power plan" i keep mine on ''power saver''....

Most people set Balanced in Windows Power Plan, but if you want the CPU to downclock at idle you'll also need to enable EIST and C1E in the BIOS. You may as well enable C3 and C6/7 also, for maximum power saving.

hello. thanks for the replies .. well I have two options in fixed mode and no low frequencies. In dynamic mode if drops to 800 mhz. I leave it in dynamic mode?
only it in dynamic mode is enabled EIST

I have wanted to know which is the clock unclore, leave it in x38

I have two options in the bios C7S and c7. when I put c7 to see a video system gets very slow

Clock Uncore? What do you mean by that?

I think this should be correct:

Base Clock: X38
Turbo Clock: To whatever multiplier you want
Disable C7 if you're having problems with it enabled.

Here's a quick overclock guide to 4.4GHz:
Warning: Spoiler! (Click to show)
1. Set "All Core" CPU Multiplier to 44X
2. Set CPU cache Multiplier also called the Ring bus multiplier to 35
3. Set Fixed CPU Vcore to 1.25 -1.30v
4. Set CPU Cache Voltage also could be called Ring Bus voltage to 1.20v -1.25vv
5. Set Vrin also called "CPU Input Voltage" To 1.9v - 2.1v

DO NOT and i repeat DO NOT mix up the "Cpu Voltage" and the "CPU Input Voltage". One is for the CPU and the other for the On Die VRM's.

Save and reboot into windows.
Use your favorite Stress tool. I used IBT on High and monitor temps with Realtemp or some other monitoring program.
Run it for 10 Runs or 20 or whoever you feel comfortable with. I run it for 10 usually. If it doesn't blue screen you after the 5th run you could assume you're stable. Again run it for as many times as you want. Get through 10 or 20 runs and no crash? Congratulations you're stable and you can fine tune.









Some extra's. Some bios' will add in a little offset voltage for both the CPU and Cache. Mine was .8 for the CPU and .4 for the Cache. If that happens put the lowest setting you can. Not "Auto" but .01 for each.
