AMD Board with 4 Dimms

wolfman

Am just posting around to see if anyone has had this problem or knows of a solution.

I recently bought another 1gb of ram, to make up 2g in my computer (4x512). It just won't work though, it won't even post.

I know the ram is ok. My current ram works fine, have tried it in a number of configurations. If I take it out and put in the new ram, that is the same and works fine. If I put everything in and use up all four slots it won't work.

I get random bios feedback, it varies, but for each instance no display or post.
- No beep, everything just powers up.
- One constant beep.
- Continuous beeps (long rather than short)
- The regular beep as if my machine was booting up ok?!

It's not PSU related, I've got a 530W Tagan and run the system with minimal hardware.

The motherbord (MSI K8N Neo2) has the latest bios update (v1.B).

Basically if I take two of the dimms out, it boots and works fine again. Put all four dimms in and it won't post. I've read on a few places this can be common with AMD boards, or at least some of the MSI ones.

Anyone got any ideas as I've just spent £65 on ram that I can't use.

What memory settings are you running, 4 sticks can be an issue with some nvidia chipsets (not just MSI - I had a K8N Neo4 SLI that ran perfectly) - if 1T drop it to 2T. There are loads of tips in relation to this particular board on xtremesystems

Some excellent stuff on there, if rather more techie than most.

Ok I'll try that, although I think all of the memory settings are set to be detected or "auto", if you know what I mean. It is currently at 1T though.

1T has been the biggest problem across the board with the nvidia boards. Dropping to 2T with 2 gig of ram isn't a great problem though, you'll still get a boost in certain apps.

You sir are a legend. Many thanks. It's all working now.

Actually looked into it a bit more, someone mentioned something about the A64's memory controller not being able to handle 2T with four dimms. Anyway, it works which is the important thing.
