Dual Channel DDR

[RoninCS]

Ok, so I have a nForce2 KT400 Ultra board, that supports dual channel setups. So today I threw a second stick of exactly the same RAM I already had in my system, and ran Sandra. Oddly, the benchmarks were lower with the second stick in running in dual channel mode (as denoted by the bios message as I booted up that stated it was in dual channel mode). Is there a reason why this would happen, aside from perhaps one of the sticks being bad?

how much memory did you have and how much do you have now? If you went form 512MB to 1GB, that might explain it as the volume of RAM may decrease bandwidth.

That's exactly what I did..went from 1 512MB stick to 2....sad, though....was hoping for a performance improvement, not a drop. :(

sisandra is unreliable anyway, screw it. 1GB of meme will be a huge difference in games then 512, especially in generals and sim city 4. and dual channel, is faster in every single way, dual channel has twice the memory bandwith and alot less latency. heh, if you dont want to run in dual channel, can i have your 512 Stick?

is anybody else confused by his "nforce2 kt400" board?

Yeah...his board is a KT400 board. And dguy6789, AMD systems won't see twice the memory bandwidth however Intel ones will.

no, its an nforce 2 ultra 400 board lol

I was waiting to see if anyone would notice :p
