With 4x512 DIMMs you have to run 2T in your memory options in your BIOS. I'm positive you have to for AMD and I'm pretty sure you do too for Intel, but I could be wrong. Try setting it to 2T and overclock a little bit. Also, with more memory sticks, the memory controller has to work much harder to address all 4 sticks which usually results in a loss of speeds in your overclock. Try raising your VDIMM a bit more to 2.9 and then overclock.

ok i will try !!! but for the 2t setting i think i dont get this option whit the intel board ....

this is my bios setting !!!

so if i undestand ... it's better to use 2 gig dual kit (2x1 gig) then 2 dual kit (4x512) ... that's right !!!!

i'll try !!!!


but notting better then stock speed whit all four bank full ... try whit only 2 and everythig is ok ....

so anybody what to buy or trade for this set of dual xp4400 from mushkin ...
