K8N Diamond - 4GB RAM only running at 333MHz?!

[CHaynes112]

I was building a PC at work for a customer and ran into a snag. It's a MSI K8N Platinum Plus, Athlon 64 X2 4800+, 4GB PC3200 RAM, and a MSI GeForce 7900GTX. The system is running 4 x 1GB chips. I did successfully enable to MemoryHole option in BIOS to enable the entire 4GB of RAM... However, my problem is, I can only get the RAM to run at 333MHz. The chip is a Rev E6, so I think it is capable of running 4 x DIMMS at 400MHz (2T of course). I understand it won't do 1T with 4 DIMMS and that's fine... but even at 2T it will NOT go above 333MHz. I even pulled out 2 DIMMS (which left 2 x 1GB = 2GB in the PC) and it would still only goto 333MHz. When I pulled 1 more DIMM out (now total of 1 x 1GB in PC) it finally went to 400MHz?! This is killing me... I know this isn't a DFI board, but I was hoping someone may have some idea? MSI's site doesn't have a BIOS manual download for it... I am gonna install Windows today and do the LiveUpdate thing to check for possible BIOS updates (however the board is brand new).

NOTE - I just looked in the book, and it says when using Double-Sided memory sticks the board will only do 400MHz with 1 stick installed. When 2-4 sticks if Double-Sided memory is installed, only 333MHz is possible?!?! AAHH!! Can this be true? I have 2 x 1GB of OCZ (double sided) in my DFI board and 400MHz is no problem at all Is this just a limitation of the MSI board? Any ideas would be greatly appreciated...

-Thanks

just put it to 400mhz in the bios??
ow, thats 200 mhz btw :p

I don't see an option to change it. It automatically shows 333MHz and it's grayed out. I don't see an option to set the actual MHz.. The only thing I see is one that says DRAM/FSB and it is set to 1/1...

In the chipset menu the first option is "Auto/Manual".. Chose manual and then 200....

Okay, I just got back to work and re-read the book... It is possible to get 400MHz with 2 DS DIMMs (I previously stated 1)... The slots are just a little different on this motherboard (on the DFI, you match Orange and Yellow... or this one you match first 2 (Blue and Purple) and last 2 (Blue and Purle)... So now I successfully have 2 x 1GB = 2GB in the PC running at 400MHz... I still can't get 4 double sided DIMMs to run at 400MHz... is this even possible on any board? I know DFI's can run 4 x DIMMs at 400MHz 2T, but maybe that is only for 4 single sided DIMMs (and not 4 double sided DIMMs)?!

Have you tried calling MSI?

There is no such menu or option...? This is the MSI K8N Diamond Plus motherboard... The "Cell Menu" is where the changes are made... I see nowhere to manually set the MHz though?!
