This memory sucks. I could get it on an Intel board doing 433 only at 3-3-3-7. On a K8V AMD64 board this thing won't do better than 3-4-4-8 even on 400. What a big difference from Winbond modules. It is really hard to understand that Winbond is not making BH-5 any more so we are reduced to Micron and similar crap, or CH-5.
