Hi wondered if anyone can help with my strange RAM issue ? I offered to upgrade my mums old packard Bell 1401 imedia desktop so I checked out its maximum RAM upgrade cappability and that is 2GB ( 2 x 1GB ) DDR 2700. I installed windows 7 ok , but the ram is proving to be a real issue !! let me explain if I put in 1 stick it works fine if I I try both sticks the PC just keeps rebooting and just wont load into windows ? if I swap the ram into opposite slots same issue , I know the ram is ok because both boot fine if installed on their own ? I know the motherboard slots are fine because I can use either individually ok? But the real wierd thing is if I swap one of the 1GB sticks for the older original 512mb and install just 1.5GB instead of 2GB it boots and runs fine ? It just wont take 2GB despite all memory sites stating this is the correct max available at 2x 1Gb ?? anyone please ? as this is driving me mad !!
