Dual channel DDR vs single channel DDR2

post #1 of 3
Thread Starter 
Just a question on something related to my HTPC

I just scored on Craigslist again, grabbing an E5200 + nForce 630a + 3GB DDR2-800 RAM [assuming 6-6-6-18 timings], among other working parts for $50. The mobo is a GeForce 7050/nForce 630a, which means no dual channel support. I'm going to be getting rid of that extra 1GB DDR2 DIMM to pay it off since it won't make a difference.

The parts will replace my old HTPC which runs a P4 3Ghz + 915G mobo + 2x1GB DDR-400 [3-3-3-8]. Now I'm pretty sure overall performance is going to jump with a C2D vs P4, but what about the memory performance? Does the double speed (DDR2-800Mhz vs DDR-400Mhz) completely make up for the fact that I'm going single channel or not? Currently the role of the PC is HTPC, so dual channel may not be very important, but I may turn it into a mixed-use rig that'll cater to a lot of people in the house, and dual channel may be more beneficial then.

I'm keeping my eye out on Craigslist for some good boards and either another 2GB DDR2 DIMM or some new DDR2 altogether anyway.

It's an HTPC.
You aren't using it for anything memory bandwidth intensive..

Not going to notice a difference.
Pop in another stick once you're about to retire it.

Sounds good. It's an E5200, and considering if these things really do get to 4Ghz easily I may want to give it a shot someday (i.e. OC to 4Ghz, give it to sis as PC for her games & all), and I'd like to have RAM that'll make the performance increase worth it.

EDIT: I am wondering how it'd stack up to the original setup [dual ch. DDR-400] though, i.e. performance numbers, comparison.
