msi neo2 using all 4 dimms

[kimc11us]

I have noticed if I use all four dimms it underclocks to 333 not 400 dual channel. IS there a way around this or is this a problem with the amd chip. I tried single 512 and was planning to get another one later for dual channel but didn't overclock any better. I am using ddr400 Cosair and ddr 400 samsung two in each dimm slot (256mb).
Please help

"The MSI K8N Neo2 was able to run with all 4 DIMM slots at the same aggressive 2-2-2-10 settings used for 2 DIMMs. However, as we have seen on the other 939 boards running all 4 DIMMs, Command Rate must be reduced to 2T when filling both Dual Channels."

Other than going down to 2T setting, it will work ok correct? Will it still overclocks? How much of a significant is it to go down to 2T?
Thanks.

1t is quite a bit faster than 2t, but you gotta do what you gotta do.

scroll down to Command per Clock and see what happened.

"So what kind of HTT increase would the 2T need in order for performance to be back on its feet? Raising HTT up to 275 seemed to help close the gap. However, the increase of HTT to 275 changed the CPU speed to 2475MHZ, 75MHZ higher than the compared 2400MHZ. A higher CPU clock and higher HTT frequency was needed in order to cope with the lowered command rate. "

If you're using double sided modules in ALL 4 slots, memory speed will be limited to 333, single channel. Look on MSI's site.
