Usually lock ups are memory related. Check that your voltage and timings are manually set to the manufacturers specs. If they say 1T command rate run a 2T command rate anyway. Your power supply may be a little under-rated as well. Have you tried running with just one card in the system?

Hi mate i have changed the command rate to T2 and put up the ram voltage to 1.9 as xfx support said to and updated the bios to po6 this has not helped i will try with only one card in. Im posting here because im sick of waiting a week to get an answer from xfx support. thanks for getting back to me.


I have taken one of the cards out and the system is still locking up
