I RMAd my first BFG 8800GT OC, as it had the wrong BIOS in it, and wasn't running at OC speeds... and in the subvendor category in GPU-Z, it was listed as NVIDIA and not BFG Tech, like the other BFG cards do.
Got this 2nd one from OCUK a few weeks ago.
Runs mostly fine.
Had a few Green Corruption problems on Crysis, and one other game once or twice... a reboot fixed it.
This one won't clock for carp either.
The clock and shaders are OK, but can't get memory above about, well I set it to 930. 950 works in some games, but others I get more green corruption and I have to hard reset the system. Clock and Shader happy at 675/1691, completed Crysis with those settings, but ram only at 1860Mhz!
(well ventilated case too, Thermaltake Armor)
Still, despite that, everything (bar Crysis of course) runs like a dream, so it will do until GeForce 9.
V1N.
EDIT: I'm sure I could get the ram above 1860Mhz, as I said, I dropped from 950 to 930, as 950 was causing trouble in Crysis (3Dmark and Lost Coast Stress test were OK though, even the infamous Freeze scene) but I just chucked it down to 930, and it worked perfectly stable, so left it there. Am considering one of those Accelero passive coolers.. maybe that would help.
