been using 1.67 since I got my board a week ago and so far nothing an RMA can't fix. lol
J/K, but I'm not sure whether it's my settings, or my VGA (9800gtx) or perhaps the fact I used PCI-E slot 4, but for some reason, it's showing up as 8x and not 16x and I only use one card. I thought it auto selected 16x when a single card was in use?
I am also using Crucial Ballistix memory that isn't on their 'guaranteed to work' chart, and at first I was tempted to send it back, but after realizing that in order for these 1333 stix to work properly, I had to manually set the timings and so far so good. Only wish I could get my system to boot up at 400 though as it just pops on and right back off.
