Overclocking a 4930k and amount of memory

post #1 of 5
Thread Starter 
I'm about to order a 4930k, with the new x79 deluxe motherboard. The memory will be corsair vengeance 1600mhz, 9-9-9-24, 1.50v.

I'm wondering if i should go with 8gb (4 x 2gb) or 16gb (4 x 4gb) of memory. I know i don't need 16gb for sure, 8gb is plenty and i'll never use 16gb for gaming.

However, i'm wondering, is it easier to obtain good CPU OC results with 8gb or with 16gb ? Or is the amount of memory irrevelant for that matter ?

thx

Don't you mean a 3930k?

Either way, if you want 16Gb go with 2x8gb to reduce the strain on the IMC. Either way it'll only hinder your OC by 200mhz

No, i really mean a i7 4930k... Ivy-E

Why would 2x8gb be preferable to 4x4gb ? the LAG 2011 platform is meant to be quad channel. That said, quad channel or not, if 2x8gb or 2x4gb is ''better'' than 4x4gb for overclocking the CPU, then ill go 2x4gb or 2x8gb for sure....

Just trying to find out what is the best possible combination that will give more chance to get a good OC on the CPU.

I'm fairly sure he did mean 4930K. No reason to get a X79 Deluxe for a 3930K...

Anyway, I'd personally go for a 4X 4GB CL9 kit. It shouldn't hinder your OC (at least didn't hinder mine though I went for a different memory kit) but if you plan on OC'ing your RAM you'll see the difference in benches.

Because of quad-channel, you can use lower speed(Hz) 4x ram to still obtain enough bandwidth. But if you only use 2x kit, you need higher speed(Hz) to make up for 50% reduction in bandwidth multiplier? Unsure if the max bandwidth is in one channel or from all channels together.

I have seen some tests where it might be quite nice to have high speed(Hz) ram in 2-channel, but with 4-channel you can in theory use 50% slower(Hz) rams to get the same result.

Also depends if you are doing something else than overclocking. Be sure to buy 2x- ,3x- or 4x-kit because they are tested to work together.
