I have my older XFX 5770 1GB model under my desk about to be shipped to a buddy in another state. I could test it since I know I never had any issues with it in my old PC. I won't disregard the main memory as being a problem. Tonight I tested the first 4GB stick, 21 passes with no errors while I was at work. I'm currently only running 2x4gb which is enough for my everyday normal tasks, and gaming. But I'll test the second stick I put in tomorrow while I'm at work, working my way through all four sticks.
I've also heard that I should test them in different slots? So since I tested the first stick in the #1 slot, I could test another in #2, #3, and last one in #4 slot to found out if one of the slots are bad? The sticks are in dual channel slots now, so although it's only 8gbs total my overall performance may increase slightly, something I may not even notice.
Thank you for your help John.
I've been having issues with Blue Screens since the very first night the system was pieced together. I had to RMA my old 5770 because it overheated 98.7C in BF3, although xfx didn't find anything wrong with the old card, they replaced it and in my opinion the replacement just seemed slower, I couldn't play on the same settings as before because the frame rate was lower. Hopefully If it turns out to be the sapphire card I won't have the same problem. If it turns out to be a bad memory stick I may go 2x8gb sticks.
Should mention that I cannot understand why it never, I mean never, has blue screened while gaming. Has when launching a game, many times while loading or watching an online video, or loading up a flash game. I was playing a flash game online the other night when I got the x50 error from Firefox. I play a lot of games, BF3, Sim City, GTA IV, Tomb Raider, Shogun, L4D one and two, Euro Truck sim, spinwheel, beamNG, and others. Mainly at 1680x1050 High/Ultra settings, max resolution supported by my Acer 22" LCD.
