Has anyone else had problems with RAM and this board? if you have this board can you tell me what brand of RAM is working for you?

It cannot support registered ECC memory. It cannot support ECC memory. FSB 333 CPU can only run at DDR 333 mode. Be more detailed with what which memory you're running. For more information check out this website it might help you out with the type of memory you need. Plus always keep everything update, yes that means your Bios that might need to be flashed. Good luck!

I think that it might be that board that I read about. It has a problem with Crucial memory. Not positive that that is the board that you have, but I know that it was one of the MSI KT4 based boards.

I have had problem considering memory with this mobo. I have used PQI PC2700 DDR module and when I've tryed to put FSB at 133 my computer (Athlon XP 2000+) crashed during windows loading. Try KINGSTON PC2700 modules, just to be sure that the memory is responsible for PC malfunction. If you experience problems with KINGSTON then think about changing mobo.
