i7 3930K plus Asus Rampage IV Extreme power help.

post #1 of 7
Thread Starter 
I'm planning on overclocking my i73930k as I just got a water cooling system up and running biggrin.gif
However I have a slight quandry- The Rampage IV Extreme has an 8pin power connector plus and additional 4 pin. I know that older CPUs just need the 4 pin, and newer ones like the 3930k need the 8 pin. My question is will i need to use the 8 and the 4 pin connector to supply enough power to my cpu for stable overclocking, or will it be fine with the 8 pin only? I'm planning on overclocking into the 4.5GHz range (as this seems relatively easy to achieve and stable for the 3930k). Any tips or advice is well appreciated smile.gif

You should be fine with just the 8 pin. The additional 4 pin is there to stabilize voltage at super high clocks by providing more power to the chip.

8 pin only, you'll need the 4 pin also if your running massive clocks like 5.1GHz and up.

4.5GHz will definately be fine with the 8 pin power plug only.

I've benched at 5.5ghz with only the 8pin. It's fine.

Be careful not to burn up the 8 pin socket area and melt it when benching at 5.5GHz. I'd use the extra 4pin in that situation.

So did you take off the cover and use the 8 pin or leave the cap on and use it as a 4 pin? I was wondering about this as well ... I just build my system last week. I am using the 4 pin and want to check to see if we need only the 4 or should we take off the cover and use the 8?

Thank you!
