32gb vs 64gb, OC issues I should be concerned with?

[djb]

Hi!

I'm building (replacing my RIVE/GTX 680) a gaming machine for surround 3D. 3 X Asus VG278H, 3 X EVGA 980 Hydro Copper, with 5930K.

In a couple years, this will be changed over to a multipurpose pc, including video editing. Probably switch the cpu at that time.

I've read here that you should get a complete "set" of memory, if you plan to add more later, thus, from reading here, got the:

G.SKILL Ripjaws 4 series 64GB (8 x 8GB) 288-Pin DDR4 SDRAM DDR4 2400 (PC4-19200) Memory KitModel F4-2400C15Q2-64GRK, as per QVL.

The bulk of the OC will be on the gpu's.

I've also read here that a few games, like Dying Light, might be best to have 32gb instead of 16gb.

Thus, my question, if I do plan to do some nominal OC to the 5930K, will I be hindering the CPU OC much by putting all 64gb of ram in, instead of just 32gb?

Thanks!

Running 64GB will tax the CPU's IMC. Not knowing your CPU's quality, it's hard to say how high you can overclock.

I just finished testing my overclock with G.Skill F4-2800C16Q-32GRK ram. I'm currently at 127.3x34 which is roughly 4333.3mhz using 1.35 volt input. Correct me if I'm wrong, I assume that a 5930k should get 100-300mhz higher than my overclock since it has two less cores.

In a perfect world, yes. 😛

Only if it is a good sample. If it is an average sample it will be limited for frequency.

Thanks guys, I guess I was asking the obvious, only one way to find out, start with 32 and see what happens! 🙂

I think I'll bench test with all the ram just to make sure I have a good set now, then yank 32 gb back out.

I appreciate all the contributions here, saves a lot of trial and error.
