Macbook crash after ram upgrade.

[richj86]

Hi.
I installed 2x2gb crucial ram in my macbook 2.1.

It all installed fine, but then after about 3 hours use, the system froze, the screen went all pixelated and a loud static screech came out the speakers.
Its done it 3-4 times in 48 hours, so im guessing its the ram.
It also gets hot just where the ram would be (but not super mega temps according to the program readout)

Im getting the ram replaced under warranty, but if it does happen again, does anybody know what to do.

Somebody on the crucial forum suggested adjusting the controller and voltage, but i dont think thats it? Can the 2.1's handel 4gb?

Put the original RAM in, or the replacement sticks. If it's all better you got bad sticks (sounds like RAM).

Do the usual - Run Disk Utility/repair disk and permissions
Zap PRAM

If still with problem, the time to get it looked at.

Yeah i just chucked the original 2x512's in now.
Hopefully it was just a bad stick, but memtest did a scan and didnt report anything.
Might have just been a pre-packed static thing.
