Z68X-UD3H B3 OC'ing help

post #1 of 6
Thread Starter 
I've built many PC's, but never OC'd before. I just purchased this motherboard, an i7 2600k, and 16gb of Corsair Vengence RAM.

I was hoping to be able to get a stable 4.5 OC that would run 24/7 for many years to come.

Is there an easy/painless way to do that? Or am I being too ambitious?

Are the OC'ing apps that came with the board any good?

Thanks in advance,
~D.

Set your multiplier to 45x, and set all of your turbo multipliers to 45x.
ENable CPU PLLOvervoltage


Now you can do two things, you can chose to have your CPU run at 4.5ghz 24/7 even when on very light loads or you can how the CPU and voltage down clock with the load.

If you want 4.5 24/7 without dropping frequency during idle, then you should set vcore to 1.35 with LLC level 7, when you boot up run some prime95, if you pass, then lower the voltage 5-10mv in steps until it become unstable at that point increase it until you find the lowest voltage at which the CPU is stable.

Now if you want 4.5ghz even in no to light load situations you can disable C1E, EIST(speed step), and C3/C6 states. If you want frequency to drop then leave these enabled.

THen if you want voltage to drop with frequency set your vcore to normal, and set DVID offse to +X.XX volts. If your vcore you find for stable is 1.35v, then your normal will show you a greyed out voltage, maybe it will be 1.20v, if that is the case setting DVID offset of +0.15 will give you 1.35v load.

Hi and thanks for your advice. I am sorry I did not reply sooner, work kept me busy.

I wasn't able to get it to stablize at 4.5. Maybe because this board only has 7 phase for power.

However, using your info I was able to get a 4.2 OC on my PC on this board. I disabled C1E, EIST(speed step), and C3/C6 states. Ran prime95 for some time with no difficulty. Eventually, the PC did reboot under Windows software control when the services.exe failed while under Prime95's torture test. But I don't think that has anything to do with the bios settings. It's been running for over a day of normal use with out a restart, So I'm thinking it looks good.

I kept an eye on the temperatures as you suggested. At 4.2 it idles at 35c, and after being max'd with Prime95, the temp peaked at 66c, but eventually stablized at 54c when the push/pull fans kicked into high gear over the radiator.

I did notice that the power requirements and heat increase dramatically on this board over 4.2 So I think I'll stop there for now. It may not be impressive as OC's go, but it's respectable.

Thank you again.

you can push 4.5ghz if you add some more vcore, you don't stress the thing 24/7 with prime95 on a normal day, the DrMOS can together provide 140A, I can do 4.5ghz 24/7 on it, in fact i actually do. You can push the vcore more, the board will shut down/throttle OC before the DrMOS burn.
