Using 1 Channel on a 939 A64?

[Gilbo]

Because the K8 has two, independent memory controllers you theoretically don't have to add DIMMs in pairs if you don't want to. Now, I know with certainty that Opterons allow this, and you can activate/inactivate memory channels in the BIOS, but I haven't been able to confirm whether 939 A64s actually do.

I'm thinking about picking up a single DIMM for a possible 939 system, instead of a pair and am trying to get some certainty as to whether this will work. Does anyone have experience, or comments regarding this?

I can confirm. It works fine with A8N-SLI Deluxe at least...

Thank you. That was fast .

While in Oregon, I semi-work from home...this page gets refreshed a LOT. I'm always in search of new projects to keep me busy.

Gee, that's odd. I remember every mfr. saying memory had to be added in pairs. * shrug*

Every manufacturer? Single channel support is now AMD's call, as they have the memory controller.

And yes, it should work (according to the people who make the chips).

IIRC, SIMMS and RIMMS were the only ones you had to use in pairs...

The only 939 boards I have used (from Gigabyte) won't boot on a single unit
