Gaming - How much performance hit running DDR3 in single channel?

[dbaaz]

Hey guys,

How much of a bottleneck should I be seeing running DDR3-1600 memory on single channel mode as opposed to dual channel?

I am using a single stick of 4GB GSkill Sniper 1600MHz memory. Getting bottlenecks in many games (GTA4, Witcher 2,NFS:MW 2012) with around 70%-80% GPU utilization, and esp. in the "Welcome to the Jungle" level in Crysis 3 where the grass pulls the FPS down to the 15's and gpu util. at 40-50%. There are also some areas in Tomb Raider that will crap on the FPS. The only games that achieve 99% utilization all the time are Max Payne 3, BF3 and Bioshock Infinite.

PS: Vsync is turned off and I am playing @ 1080p

Me thinks that my FX-6100 ss the source of the problem, but I wanted to know how much of a bottleneck single channel RAM will create.

Will update sig with specs right away.

FX-6100 @ 4.2GHz | 1x G.Skill Sniper 4GB|Gigabyte GA-78LMT-S2PT|Seasonic S12II 520 Watts |Sapphire Radeon HD 7850 2GB

GTA is a port from console, on my PC it uses about 70 of GPU and up to 100% of my CPU.

Ram shouldn't cause any bottle neck of the GPU.

Also you should add specs to your post, sigs tend to change over time.

Thank you

Wish that review sites also included a single vs dual channel comparison. Instead of the usual dual vs quad comparison.

Most people use 2 or 4, just going with the masses lol.

your cpu is shit at single threading, that's what causes the fps drops. got the same problems with my fx-4100, luckily i will get rid of that thing within the next few days.
