Two 4 GB RAM or one 8 GB RAM
Hi,
Can someone tell me whats the performance difference between one 8 GB RAM stick & two 4 GB Ram stick.
Configs for both are same.
My entire config.
i5-4670K,
z87 extreme 3 MB,
8 GB corsair Vengeance RAM Stick,
Corsair PSU 600 Watts,
Nvidia Gtx 760.
Thanks in Advance.
- plef 13y agoThe 1 x 8GB will run on single channel mode, when the 2 x 4GB will run on dual channel mode aka double performance (double bandwidth to be exact).
- tuananh 13y agois this still true until now? I remember reading about this few years back.
- ankit_1990 13y agoHi tuananh, Can you give me some links that tell me more about this thing. Thanks in advance.
- tuananh 13y agoYou can read more about this on Intel.com (http://www.intel.com/support/motherboards/desktop/sb/CS-011965.htm#dual http://www.intel.com/support/motherboards/desktop/sb/CS-0119...)
- devx 13y agoI would go for 1x8GB if you want to upgrade it in the future with another 8 GB.
- ankit_1990 13y agoI am not going to upgrade atleast for a year. What would you recommend me then ?? my MB has 4 slots...
- cnvogel 13y agoDepending on your CPU and its integrated memory controller, you might have one, two, three or even four "channels" that can work concurrently. The i5-4670K has two channels. While this sounds like a huge possibility for performance imporovement, in practice the gain is on the single-percent level. It can be measured, but to actually feel the difference during use of the machine, you'll need something like a 50% speedup. http://www.tomshardware.com/reviews/Intel-Core-i7-Nehalem,2057-13.html http://www.tomshardware.com/reviews/Intel-Core-i7-Nehalem,20... So for a desktop machine, I'd say it does not matter at all. Buy what's more affordable, and maybe think about possible future upgrades.
