Installed a new 8RDA+ today with a T-bred 2100 B. This one is a good board, out of the box removed nothbridge cooler an installed my custom built one, passive heatsink on south bridge, mosfets,an power chip. With no vdd mod runs 210fsb with mem at 2.77v an no screen flickering. Expert,aggressive,100%,4,2,2,2 with a stick of 256meg Corsair PC3200. At 215fsb with mem at 2.9v Win 2000 would freeze during load an raising the
vcore made on difference. So the limit of the mobo with 1.58v vdd is 210 which is very good. Right now been running Prime95 at 12x205 (2470mhz), mem 2.77v,
cpu 1.85v for 4 hours. Don't know if I will vdd mod this one it runs so good.
Cpu was in my 8K3A+ an prime stable at 2510 at 1.85v, so I will see if it will get back there an maybe a little more. I am very pleased with this board.
