1st , I need to give major props to Mr. Fox. My M17xR4 runs well , I added a 970M and I'm jazzed Mr Fox.you are my new hero!! ( alittle throttling ,but I OC it mildly). Now to my puzzelment,.......Picked up some basket case M18xR2's and put in an 970m, along w/ 32GB of hyperX @2133 , a 3940XM, crucial 920GB C drive , a 512GB Msata along w/ a WD750GB drive(7200). Working w/ Win 8.1 and trying to get thru all the steps for this damn card to work( BTW , I'm not going to SLI unless I go backwards to snag a pair of 680M's) almost drove me to toss this as deep in the ocean as I could on my dives...........maybe deeper. Using a clean install of WIN 7 everything runs great ( I can even run alot of earlier games on the IGFX), ADD the 970M...............8 beeps,pull the card and post's with no issues. any ideas would be greatly appreciated.I'm tempted to pull the 970M from my M17xR4 but I hate easter egg troubleshooting and I don't want to kill the card. Maybe put the suspect card in the 17x and see if it posts on the platform that works......???
