DDR400 showing as DDR333

[daiondoroga]

I have an ECS Nforce3-A (please no comments about getting a new MB, I know I need to ) with a Sempron 3100+. I just bought two new sticks of 1GB PQI PC3200 DDR400 Single Channel RAM.

If I have one stick in the system it shows as DDR400. If I put both sticks in the BIOS shows DDR333.

Is this common? I've checked both sticks seperately and they both show DDR400.

Your motherboard simply might not be able to run the sticks at DDR400. Do you know if the sticks are running in 1T or 2T Command Rate. I have the same chip running in an Nforce4 Asrock board, and when I had 2x1GB Mushkin sticks running in 1T the motherboard ran them at DDR266. See if you can find a setting for command rate and set it to 2.

Alternatively, you may have a very weak memory controller in the cpu, but I'm not too short about that.
