G skill eco vs corsair xms

[mxp12]

Hi guys, I'm currently thinking of replacing my current memory, a 2x2gb corsair xms 1600 cl7 1.65v to a g skill eco 1600 cl7 1.35v. my current specs are core i5 760 cpu, asus p7p55d-e pro mobo, gtx 460 1gb cyclone vidcard, corsair hx650 psu, coolermaster hyper 212 plus cooler. I also plan to overclock. I think the lower voltage would give a better performance but I'm not sure. Do you guys think the g skills would be better or should I just stick with the corsairs? Thanks in advance

Define 'replacing'? If you're thinking that trashing the 'Corsair XMS 1600' for 'G.SKILL ECO 1600' then don't. Also, if you're thinking of combining the two (2) sets then don't.

Instead keep the 'Corsair XMS 1600' and get and identical set of 'Corsair XMS 1600' -- 8GB total of MATCHING RAM.

I meant I'm going to take the corsairs off my rig, put them in another rig and get the g skill ecos

You need to verify that that are {new & old} compatible; please post both MOBOs and both sets of RAM part-numbers.

You can do this yourself:
Corsair Configuration - http://www.corsair.com/configurator/default.aspx
G.SKILL Configuration - http://gskill.com/configurator.php

Good Luck!

I know that it is compatible. My question is that if the g skill rams would be an improvement over my corsairs because i was thinking the lower power requirement would mean lower heat and better overclockability. Thanks again

Post the EXACT links, it depends upon the IC's not so much the CAS or Speed and particularly the CAS tightness -- people for some reason haven't figured this out.

Example:
8-8-8-24 is typically Better than 7-8-7-24 at the same speed, and some 1333 is as fast as many 1600.

1600 7-8-7-24-2N 1.35v

Just NEVER mix them on the SAME MOBO together, and both are average. Both sets are relatively close but my guess is the Corsair is slightly faster - neither is a good OC set.

For another few bucks I would recommend the following Corsair set that I know is both faster and OC's very well. It also has a 2X4GB sister that is also an excellent choice.
CMP4GX3M2A1600C8
1600 8-8-8-24-2T 1.65v
