64 GB Ram = 2x32 GB (4x8GB) Ram?

post #1 of 29

Thread Starter 
Hi,

My intention is to build a new system based on X79 motherboard with 64 GB Ram.
My question is:
Is it safe&secure to build such a 64 GB Ram system using 2 x Corsair Dominator 32GB (4x8GB) 1600MHz Quad Channel Kit? Or maybe GeIL EVO Corsa 32GB (4x8GB) DDR3 1600MHz Quad Channel Kit.
As for motherboard, I was thinking that Asus P9X79 PRO will be a good choice.
Or maybe Asus P9X79 WS Intel X79 motherboard might be a safer choice?
Even though a bit of overclocking doesn't hurt, I'm mainly interested to have a stable system.
Any help will be highly appreciated.
Thanks in advance for your feedback.

The stress on the IMC with 64GBs of RAM (essentially filling all of the RAM slots) will make overclocking pretty much an impossibility. Well, at least an overclock that would even be worth it.

Isn't that only true for overclocking of the RAM itself? If you keep your RAM at stock speeds you shouldn't have any issues.

Nope this is from first hand experience with 16GBs. Its pretty hard to stabilize it. frown.gif

Correct, but for example.. when you're buying DDR3 1600 rated RAM, do you buy it to run it at 1333, or 1600? The more sticks you add, the more difficult it becomes to achieve that 1600 goal without adding extra voltage, which adds even more stress on the memory controller, thus adding further difficulty in overclocking in itself.

Either that or you can't stabilize the RAM at all.

I thought x79 set ups could handle loaded slots with 1600mhz. My bad.

Yeah it's do-able. You need windows 7 professional or higher to use more than 16GB though.

There may be some limitation, but it's highly unlikely to be anywhere near as dramatic as this.

You think so? I'd be curious to see, actually.

I wouldn't think you would have too much an issue with all the RAM slots populated! I have all the RAM slots populated on my 2700K, that's 2 sticks per channel, the same as the OP is asking about, and I have it running at 1866MHz with only a 0.05v bump to the IMC and the RAM for good measure and it hasn't had any negative effect on CPU overclocking at all! I'm running 4.6GHz, just as I was when I only had 2 sticks.

If you need the RAM then go for it! You'll be fine!
