I'm going to try this again, I bought the following put it all together without changing anything in the BIOS it worked for 3 weeks then I started getting corrupt data, and BSOD's.
TA790GX A2+ r5.1 (newest BIOS)
AM2 Bristbane 5000+ (non-BE) (stock 1.325V my computer 1.295V)
2x 1Gb Crucial Ballistix DDR2 1066 (stock voltage is 2.2V my computer ran it at 1.8V clocked down 7x)
Antec True Power 2.0 500w dedicated 12V+1 18A 12V+2 18A
Seagate SATA 250Gb HDD
I've run memtest+ that comes built in to motherboard which gave a ton of errors running ram at 1.8V, ran test again with ram at 2.2V and had no errors.
I've run Seagate Hard drive utilities and it's fine.
I reformatted the computer with Win XP SP3. installed all the drivers, chipset software (got an error trying to install this stating the device did not exist)
I also read some where that my Avast! anti-virus was causing data corruption and the BSOD not playing nice with other software....
