Corsair VSA4GSDSKIT667C4 won't boot

[KeitaroBR]

Hi all,

I've bought the Corsair VSA4GSDSKIT667C4 set (2x2GB) for my MacBook MB403LL/A.

But it won't boot if both memories are installed. If I install one of the new memories with an old one, it works perfectly.

Any idea why this is happening?

Regards

Almost definitely bad RAM, get a replacement.

If it were bad RAM, why would they work together with the old memory but not alone?


I've been reading around and some people say it may be related to the new memory's SPD settings...
