ga-x99-ud4 fast ram

Hi all!

I'm looking to upgrade to 64GB of ram for the above motherboard, but I want to use 16GB modules so that I have the option of extending to 128GB in the future.

I was considering this RAM: https://www.overclockers.co.uk/cors...channel-kit-black-cmk32gx4m2b3-my-474-cs.html

The gigabyte website for my mobo states:

8 x DDR4 DIMM sockets supporting up to 128 GB of system memory
* Due to a Windows 32-bit operating system limitation, when more than 4 GB of physical memory is installed, the actual memory size displayed will be less than the size of the physical memory installed.
4 channel memory architecture
Support for DDR4 3333(O.C.) / 3200(O.C.) / 3000(O.C.) / 2800(O.C.) / 2666(O.C.) / 2400(O.C.) / 2133 MHz memory modules
Support for non-ECC memory modules
Support for Extreme Memory Profile (XMP) memory modules
Support for RDIMM 1Rx8 memory modules (operate in non-ECC mode)

Can anyone foresee any compatibility issues?

Thanks!

I think you would get better performance by using 4 sticks in a quad setup rather than going for speed alone, also early CPUs and X99 boards are a bit harder to get working with fast RAM, stick to 2400-2666-3000 tops.

I'd be going for 4 sticks for now (16gb each), but leave 4 slots free for possible upgrades in the future

Ok good point, I'll have a look at 3000mhz modules now, thanks!

I'm reading an indepth article on 2133mhz ddr4 vs 3200mhz, and they say that in the real world there is little performance gain.

Which is making me think that I should just buy matching modules for my current ram. I can get an additional 32GB for £130, which is far cheaper than the £400 needed for 64GB of 3000mhz ram..

I don't think I will upgrade to 128gb in the forseeable, so when I do I can bin the whole lot of ram and get new stuff.

Unless anyone has anything to counter the argument about the difference in speed being big?
