Guys, Epox put an overvoltage limiter in the Rev. 1.1 boards, hard to say when, but after 4-25-03 or so. The batch date is on the outside of the box; the date above would read -030425xxx.
The board to get is one made from 1-03 to the date above. These will have the Crush 18D chipset to guarantee 200+ fsb and no overvolt limiter. I have a 4-23 board I got a year ago and I can boot >1.925 no problem. I got a Rev. 2.0 and could not boot over that. Morever, it undervolted the voltages and could not overclock higher than my good 1.1 board, even with the adjustable VDD. The 1.1 overvolts VCORE by .02-03. I got rid of the Rev. 2.0.
Further proof? I am in Japan and there are lots of used boards here. I just picked up a 'used' 8RDA+, 1.1 dated 4-25-03, just two weeks older than my first board. Sure enough, can boot at 1.95, overvolts VCORE, and have no trouble running 214-217 fsb in DC. The board in fact looks new and is probably unsold stock.
NO doubt the Rev. 2.1+ boards all have the overvolt protection. I hear on the later revs. you cannot disable it by cutting a trace either.
Now the boards made before 1-03 won't have the overvolt limiter, but they won't have the revised 18D chipset that guarantees 200+ fsb. That's why guys who bought the very first boards had a hard time breaking the 200 fsb barrier.
