The weird thing with my NF590 Asus Crosshair is it starts to lose dividers as the HTT is raised. With the Sempron 2800+, up to around 260 HTT all the divders work. Around 270, then the DDR2-400 /8 divider stops working. Around 280, then the DDR2-533 /6 and DDR2-667 /5 go as well. 300+, only the DDR2-800 /5 divider works. Which doesn't make sense since it's the same /5 as DDR2-667. Mind you this is with 2x1GB of RAM, so I was convinced it had something to do with the IMC, but I was told it was something to do with the chipset. With 2x256MB of RAM, all the dividers work and I can get to 370 no problem before my RAM gives out. I experienced something similar when using an X2 3800+ and 2x1GB, as the HTT was raised the dividers would stop working unless I adjusted the clock skew. However with the Sempron NOTHING works.
