Re: Bad Ram?
IMO, set the specs of the ram up in the BIOS.... AMD processors usualy need looser timings on the ram they work with than what is stated it seems like... But yea, set everything manualy in the BIOS for the RAM if possible. Then run Memtest 86+ on the suckers, all together, if they still fail, do each seperatly, in there slot... Like stick one in slot A1, stick two in slot A2, stick 3 in slot B1 and so on....
It very well could be that the processors memory controller isn't working correctly, or there is a fault on the motherboard with all four dimms.
