Single channel vs dual channel?

post #1 of 9
Thread Starter 
I just purchased a z77 motherboard AsRock Extreme4 for a build I'm doing for my boss (pharmacist).
http://www.newegg.com/Product/Product.aspx?Item=N82E16813157293

The board came with 8GB Crucial RAM but it's only 1 stick, so it can only run in single channel mode:
http://www.newegg.com/Product/Product.aspx?Item=N82E16820148661&Tpk=bls8g3d1609es2lx0&IsVirtualParent=1

All my other PC's I have had dual channel memory, so I'm trying to figure out the Pros (if there are any) or cons, and how they would affect overclocking or using the PC for general use (as he intends to do, no gaming)

Thank you!

the performance difference will not be noticable; ~5% in benchmarks.

It doesn't matter too much in real-life usage. Slightly slower in benchmarks like SiSoft Sandra, but nothing noticeable in real life.

Getting the 1x8GB kit for free is a great thing, given the rise in DDR3 pricing in the last several months.

you will be fine and using just the 8Gb stick that came with the mobo will have no affect on general use or overclocking not that i think your boss needs to overclock his rig.

i have not really noticed a huge difference when i run single channel to dual accept for loading times on programs sometimes but never made huge difference that i would say its must have single stick ram would be more then fine for use

Theoreticly dual-channel memory doubles the bandwidth, but it will not have any (significant) effect on every-day usage.
post #7 of 9
What is real life usage? It depends who's real life. Dual Channel may not benefit basic users as much, but fact is there is a positive difference in performance that the computer was designed for. I would hate to do 3D rendering in single channel mode. It would take a life time.

Of course there is a difference. The question is, will you notice it? If you don't, then maybe single channel is good enough for you. smile.gif
