I'm on my second go around with this computer for work. before the first shipping problem when UPS droped the whole computer and cracked the board in half. I know the builder had to send for a replacment board. now since all that is in the past I get it here and it's being funky I have 12 gig's installed in it. the thing only shows 8 at the max I played the ram swaping to check the chips out they are all good. I found the last 2 slots are not working. but when I was messing around when it only had 8 gig's installed I put another 2 gigs in the last slot and when I re booted it instead of it saying 10 or 8 gig it only said 6 installed. This problem has been going on for 3 months trying to get this computer here and workign. I'm at a loss of words not counting the contracts I've lost due to not having a work computer for my graphics company. any idea what could be going on? If i have to replace it. What should I use as a replacment. I never had problems with that brand in the past. I starting looking at a RAMPAGEIIIEXTREME. I'm so out of touch with hardware. I can't tell if I'm getting the shaft any more.
