The Tyan K7 Thunder is one of the most stable boards that I have ever used for the AMD platform, I am running a Tyan K7 with 2 x 1200Mhz AthlonMP's, 1GB PC2100 Reg. ECC Crucial, 4 x Seagate X15's RAID 0 + 1 on a Adaptec 3200S, Elsa GeForce 3, Lian Li PC 70, Win2K Server. If only other DDR boards would use the AMD Southbridge, It would make them a lot more stable. I am anxious to try another Dual Socket A board when they come out.
