Ram Combo preference?

4x2 for dual channel 8x1 if you think you may upgrade to 16gb (assuming your mobo only has 2 ram slots). Basically you want 2 ram sticks in so you can benefit from dual channels.
 
yeah! This is what I am thinking I'll expand it in future if required but why everyone saying 4x2----- I mean 4x2 & 8x1 means a total of 8 Gb ram so why go for 2 instead of 1
 
Dual channel means that you have two channels/pathways for your CPU to access your RAM rather than one in single channel.
Running in dual channel mode is slightly faster (4x2). Maybe 5% or a little more.

So if you will upgrade sometime id go for 8x1 and take the slight performance hit in single channel mode.
 
Check out the following test someone did, here is their conclusion:

FINAL CONCLUSION OR TL;DR:
Have I proven that there is no difference between single vs dual channel RAM? No, I have not. However, I probably have proven that in (most? I can't count 2 games as most can I?) games, video and audio encoding, there is zero (negligible? near zero?) performance gain to be had in faster RAM.

Not enough games tested. Portal 2 doesn't need that many resources, don't know about Guild Wars 2 but I do remember giving a friend a 6fps increase in Crysis just by moving a ram stick over to enable Dual Channel on a LGA775 board (which admittedly had half the memory throughput of even AMD64 machines).

That guy's benchmarks are totally inaccurate, his methodology is fundamentally flawed.

Obviously RAM speed isn't going to make a meaningful difference when you're running into CPU and GPU bottlenecks. Using GW2 as a benchmark at 1440p on a 670 2Gb and an i5 3570k? What? I didn't bother reading the comments, but i'm sure they're full of people calling this guy out for poor methodology.

4x2 is faster than 8x1, period. Whether faster RAM read/write significantly impacts the workload in question is an entirely different question.
