I have a HP Elite 7100 desktop with 2 x 1Gb RAM in it running XP.
I'm about to upgrade it to windows 7 64 bit and bought another two 1Gb memory sticks.
I installed them and when i boot up the desktop it loads to the windows desktop and i can use it for 10 -20sec but them it just clicks off and automatically reloads.
I thought the new memory and the original weren't compatible so
I tried putting the new 2 x 1Gb in on it's own and exactly the same thing happens.
when i just have the original 2Gb in it works fine.
I've noticed the memory has a different part no...
The original is:- 1GB 1RX8 PC3-10600U-9-A0
The new is:- 1GB 1RX8 PC3-10600U-9-AP
Knowing nothing about memory is the AP so different to the A0 that it wouldn't be compatable with the HP Elite 7100 or is the memory defective.
