I've gotr a K7VMA in my primary rig. It was running great for 5 months, with the CPU oced to 112 fsb. The ATA/100 wasn't working but that didn't really effect performance. I found out recently that I all this time had been running my RAM @ PC100, silly me. Ever since then I've been having issues when running the RAM at PC133 and oced. It will be giving me trouble when at a mild oc (105fsb), and PC133, using the fastest timings (CAS2, 2-Bank Interleave) but when I switch the RAM back to PC100, problems disapper. I'm trying to figure out weather I just can't oc at PC133 (whch Is understandable, it's not an ocing board), or weather this board has some serious issues while running @ PC133. I'll let u know how it turns out. From what I know, K7SEM is a great baord though.
