Macbook Ram Upgrade Problem

6y, 5m agoPosted 6 years, 5 months ago
I've got a macbook with the following spec:

13.3-inch
CPU: Intel Core2Duo 2.2 GHZ
RAM: 2X512 MB PC2-5300 DDR2
FSB: 800MHZ
HDD: 160 GB
SD-DL:BLACK
model: MB063LL/B
MacBook (13-inch, Late 2007)
Macbook3,1

Currently has 1GB of RAM in a 2x512MB config. I've bought 4GB (2x2GB PC2-5300 DDR2 667MHZ) and was hoping to upgrade it to it's maximum of 4GB, but whenever I install both dimms the machine won't power up, I just get a black screen (but the sleep light comes on).

It powers up if I just use 1 of the sticks or 1 of the 2gb sticks + a 512MB or 1GB stick and successfully boots showing either 2.5GB or 3GB respectively, but it just won't work with the 4GBs.

I've updated to 10.6.3 and am running EFI v1.4.

Does anyone know a way around this problem, I've tried google but not had much luck, any help will be greatly appreciated and REP will be given.

Thanks in advance!

well you cant fix with what you have, if it wont boot, it isnt going to work
sell the other stick, use the 2+1 to make 3gb

Thanks for the advice, what makes you so sure it won't work, as I've seen other people with exactly the same setup install 4gb's (even older mac's still work with the 4gb but can only utilise 3gb).

A c2d cpu with an 800mz fsb should be able to access 4gb, no? Also do you know how to tell what chipset a macbook has?)

Just ran the crucial Mac scanner and it shows that I can install 4GB and suggest I replace the 1gb with a 2gb, so not sure why it's not working.

either you got the wrong ram (so still need to sell at least one) or macbook is wonky, either way thats the situation, go for the 3gb that works and recoup a few quid for the other stick and sell it
as you ran the crucial scanner, did you buy that ram that crucial suggests or just buy similar ram from a cheaper supplier?

Yeah your right, just bought similar RAM from a cheaper seller, Guess I'll be sending it back and purchasing the crucial RAM. Thanks for your help. Rep left!

I just pay crucial for the ram it suggest, for me it isnt worth the hassle of a few quid for good service a quality ram, crucial ram is used by a lot of pc makers
