I bought two of these from Newegg.com on May 19th. Wish I'd stuck with my original plan to buy retail Abit MBs instead. One was unstable and crashed while flashing the BIOS...rendering it useless. The other rebooted spontaneously for no good reason from time to time, though it did take the BIOS update. Incidentally, I was using two JIUHB XP1700+ processors with copper heatsinks and fans. They are kick ass processors, by the way, but everyone knows this already.
Neither motherboard would accept my new OC System PC3200 CAS2, CL2 RAM at any speed above PC2100..even at very conservative CAS settings. Ok, the RAM problem is probably because A7N8X boards are known to be VERY picky on RAM, so beware this combo.
It was all too much drama. I RMA'd the MBs back today for a refund...less my hard earned 15% lesson/restocking fee. I also returned the OC System memory...all four sticks of 512MB goodness. I was most disappointed in the RAM. They only charged me a $10 RMA fee to cover the free shipping when I ordered it. I figure that was ok.
I'm just throwing in my experience in case anyone else is thinking about the above combo or just the refurb MBs. Go for it if you like to tinker like I do, but definitely be prepared to give up some RMA $$$ if it doesn't work out.
