Hello , i just got the 2x2gb memory modules from OMNI technologies, and it just wont start with 4gb. (ddr2-PC2-5300 667mhz ram)
when I install both 2gb modules on the 2 slots available and turn on the computer, the led just stays on, the screen and computer doesn't start at all.
I decided to try them separately , and install just one of the 2gb module in one slot and leave the 512mb memory module on the other slot , the computer works and runs perfectly with this configuration (2.5gb)
So I imagine one of the 2gb modules was damaged, then again... I change it for the other 2gb module and the other 512mb ram combined, change them in different slot positions and both work combined with the 512 mb. So when I start the computer I got 2.5 gb of memory.
The problem comes only when I use the 2 (2gb ) modules at the same time, for a 4gb setup. It just wont start , anyone knows how can I solve this ?
both memory modules are said to be 100% compatible with this specific macbook model.
my macbook is 2.2ghz early 2008. so it should run with 4gb but it isn't.
help me please !
thanks
