Memory Upgrade

jjd323 · 18 Aug 2015 at 12:09

I have a need to upgrade the memory in my system to the maximum possible for a given cost, for data analysis and simulation purposes .

I have this system, with some minor upgrades, summary specification below :
Intel Core i7-3820 3.60GHz (Sandybridge-E) Socket LGA2011 Processor - Retail
Asus P9X79 PRO Intel X79 (Socket 2011) DDR3 Motherboard
GSkill Ripjaws Z Series 1600 CL 9.0 16GB Memory Kit - Red (4x 4GB, DDR3, Quad Channel, Intel XMP Certified)
OcUK GeForce GTX 970 "NVIDIA 970 Cooler Edition" 4096MB
OCZ ZS Series 750W PSU

I am interested in possibly 8x8Gb but am not clear what limitations my system would face.

a) Can my system support 64Gb of RAM? - probably, yes
b) Is DDR3 my only option ~~or can I consider DDR4~~? - DDR3 is ony option, cannot use DDR4
c) Is the "budget" option of an additional 32Gb (4x8Gb) compatible with the G-Skill RAM I have currently?

You can only use DDR3 with that motherboard/cpu setup.

You could buy 4 sets of this:

£263.95 for 64gb of DDR3.

Is it essential that I but 1600Mhz RAM if I intend to use it alongside the GSkill Ripjaws Z Series 1600 CL 9.0 16GB Memory Kit I already have? Is there a reason to not go with CL10 if I find that cheaper than CL9 equivalent?

Am considering putting in 4x8Gb alongside the 4x4Gb I already have.
