ahhh give it a try thx!

edit: mmh had memory hole remapping enabled already, i think this is necessary for the bios to recognize 4gb...

enabled memory hole instead.. did not really help.. following tests with/without memory hole enabled were the same..

266x12 DDR800 HTx5= 3,2Ghz cpu 1066mem is rockstable

275x12 DDR667 HTx5= 3,3Ghz cpu ~840mem is at least 2h primestable

320x10 DDR667 HTx4(3,2,1) wont boot

320x10 DDR533 HTx4 boot

330x10(8,6) DDR533(400) HTx4(3,2,1) wont boot

looks like imc/memory issue right? upping nb/ht (mobo) voltages didnt help..

Usually its the CPU which is the limiting factor with AMD and some CPU's just don't care for certain multies no matter what you do with them and I can attest to that throuh experience with some of the 939 Opterons whats you're HT Multiplier at 800? thats what I run mine at!

Thanks Oliverda I like the Bios as well

Yes I believe its the CPU.. I'm running HTx5 (1 Ghz) 24/7 (1330Mhz HT gives me 300Points more in 3dmark06 I like this about the am2+, someone from forumdeluxx has his running @ 1600Mhz with an x2 no problem...)

Besides the described limitations i'm very pleased with board and bios as well.

A dram skew option would be nice whatsoever

Thanks for your help and advice!

Öse..

Try dropping down to X4 = 800HT and lowering you're Multiplier
Look at the Bios Templates Overclocks I did on the First page of this thread and see if you can get any love with those guide lines
