Memory Compatibily??? What are my options???

post #1 of 4
Thread Starter 
Okay so I have this: CMT4GX3M2A2133C9

CORSAIR DOMINATOR GT 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 2133 Desktop Memory Model CMT4GX3M2A2133C9


They are 1.65v dimms

I figured I should upgrade to 8GB playing Skyrim now. Too bad; discontinued! Grr.. Just bought those this summer. geesh

So what now? The only place I could find them was at some rinky-dink site. No thanks! Don't trust places like that!

Newegg has this: CMZ8GX3M2A2133C11R
CORSAIR Vengeance 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 2133 Desktop Memory Model

It is 1.5v

So I obviously can't mix them, right? I'm just not sure here, because I was doing a power search on the egg and options are for a wide variance in voltages. For Example, you can select 1.5v through 1.65v memory in a power search. Are they implying these voltages can be mixed? I know voltages will be set to one set integer in the BIOS. I know there is a small tolerance you can play with voltages while overclocking, but I want stability! I've never even mixed brands before, let alone voltages. ???

What are my options here?

Thanks! smile.gif

EDIT: Forgot to mention I just sold my ITX Case and PSU below. Purchased this:

ASUS Maximus IV Gene-Z LGA 1155 Intel Z68 HDMI SATA 6Gb/s USB 3.0 Micro ATX Intel Motherboard

Fractal Design Arc Mini Black High Performance PC Computer Case w/ USB 3.0 and 3 Fractal Design Silent Fans

I'm doing something similar to you; going from 4 to 8 gigs.
It's not really advisable to mix two different sets of ram, especially when they have different capacities and voltages.
The 8 gig kit also has different timings, 11-11-11-27 compared to 9-10-9-27.
You could possibly run both kits at 1.65v and timings between 9-10-9-27 and 11-11-11-27, but it would depend on how well the new ram kit overclocks.
Having 4 DIMM's could also effect your overclock as it is more strain on your memory controller.
I would say sell the old kit and buy the new one.

Thanks for the reply. I think that's the same conclusion I'm coming to. So what is my RAM even worth?

I've been reading the Maximus IV Gene threads. Looking at a G-Skill set now. Spent $130 on my ram. Kinda suck they discontinued it the same year it came out?! WTH is up with that?! Geesh...

I would ask on the appraisals section.
I'm getting a gskill kit, but mine is 1600 MHz.
