Am I running in Dual or Single Channel Mode?

alexondrums · 08-21-2008, 06:44 AM

I’ve just built a new computer, however I’m having trouble understanding the dual channel RAM configuration. If you refer to the attached image, I have currently installed my 2 DIMMS in A1 and A2. I can’t work out if the pairing is associated by the letter (A/B), number (1/2) or colour (black/yellow). If I am to run these DIMMs as dual channel, where should they go?

I think maybe one DIMM should be in A1, and the other in B1?

Just out of curiosity, If I am running in single channel mode, how much performance improvement should I notice in dual-channel mode?

Hi,
DIMM A1 and DIMM B1
or
All four occupied.
For optimal Dual Channel performance the RAM should be identical in every respect. It DOUBLES the data throughput from RAM to the memory controller.

Matching colors, in this case, both yellows.
