I have a custom made desktop computer with an Asus M2N-SLI Deluxe motherboard. The motherboard has four slots and the Asus specs says it should be able to handle up to 8 GB memory. I run XP professional 32 bt, so there is no point in putting more than 4 GB in the machine. For the past 5 years, I have had two 1GB cards which have worked fine (Princeton VPM800NU005/1GB/K). I want to expand to four 1 GB cards. I bought two Spectek 1 GB DDR2 - 800 cards to go in the vacant slots. When I put in all four cards, the computer will not boot.
When I put the old cards in the once vacant slots, the computer recognizes 2 GB, so all of the slots work fine. When I pull out the old RAM and put in the two new RAMs, the computer recognizes the 2 GB cards and everything works fine. All the slots work, all the RAM works, they just won't work all together. The builder can't explain it. Please help!
