I have an e4300 in a P5K-VM and can't go past about 340 FSB. I believe this motherboard can run up to around 400fsb, no? It's not my processor because I lowered the multiplier to 7 and it's not my ram because it's 800mhz running at only 667 (with my 333fsb). Still, whenever I go past 340 FSB it's no post. I believe the problem is with the crappy aluminum heatsinks on the chipsets, causing one of them to overheat, but can anyone verify this?
