Regarding a Aspire AXC-704 ... Which has two slots for RAM, and comes with one of them filled with a 4GB RAM chip.
The SN of the one the PC came with is: DIMM KN4GB0G029625037363000
As led by Crucial.com, i then purchased a 3rd party separate 4GB chip on Amazon. Info on it:
Type: 4GB DDR3L 1600
But the computer doesn't start up when this chip is put into the additional slot. Here's the strange thing.. If I remove the original RAM chip that came with the PC, and put the Timetec chip in it's place, then it does work. In other words, the computer works fine with each chip works by itself (and thus with 4GB of RAM), but the the computer doesn't work with both.
I've tried updating the "control chipset" drivers and BIOS on the machine... No luck
Any suggestions/help appreciated
