Hi there pepz. Here comes my story. Recently i build my self a new computer have been doing this for years now, so nothing new to me. the problems started when i when into the bios after completing the build and starting up for the first time. i saw that the bios only found either 4080, or 6130, ram depending on how i switched them around, did alot of testing and found the motherboard to be fault, cause of some bent CPU pins, the motherboard then got RMA'ed. got the new motherboard, still same type a few days ago, and thought everything to be bliss, i fired up the machine, and STILL it wouldn detect my ram, i then tested the ram alot over the next few days, and found them to be faulty, couldn run memtest on one of the dimms, they also got RMA'ed, in the meantime, i then got my self some other ram, so that i could test to see if it was the motherboard i was to blame still, well guess what these ram also dont get detected for there full amount. the first ram kit, was from corsair, 3X2 GB triple channel kit, Dominator GT edtion, those were the ones that got RMA'ed. the second kit, also from corsair is the more mainstream gamer kit XMS 6X2 GB tripple channel kit. so the only thing i can think of to blame now, must be the CPU that somehow ****s the system up. do you have any experince with the problems im having ? if so please do comment and try to help me out as im running out of ideas and patience with this faulty build. Build consist of: Motherboard: Asus Rampage extreme III ( have had 2 of em, one got RMA'ed and the other is in the computer now.) Memory at the moment is these HX3X12G1600C9, and the ones that got RMA'ed is these CMG6GX3M3A2000C8. Harddisk: Intel SSD for System, and a Western digital veloci raptor for space. Soundcard is from Auzentech, there Xfi Forte. Graphic card is a ATI Radeon 5970 black edition, the ones with 2 GPU'es. Chassis - Corsair Obsidian 800D. PSU - From coolermaster there silent pro 1000W. Last but not least, a Quick Question, if any have this board, would you the plug in the ekstra 2 EZ power connecters on the board, for exstra power to the graphic card ?. Any help would be welcome. Thanks in advance.
