I currently have 8gb of ram. 2gb in 4 slots. i have two vacant slots. Computer will allow up to 24gb. Took one of the ram sticks with me to Fry's to get an 8gb stick thats compatible to get a total of 16gb. They gave me a patriot ddr3 8gb stick. I brought it home and installed it but havent had any luck. After i added it, system properties showed 6gb, so it went down by 2. Took all 4x2gb sticks out and only put in new 8gb stick. Powered it up and would just beep, wouldnt boot up. I checked to make sure it was seated correctly, and same result. According to patriot website, this stick is only compatible with a intel 2nd gen cpu. I'm thinking my i7-930 may be a first gen and thats why im having trouble?
