I returned the old ram and it booted fine. I ran Crucial websites scan which told me the outgoing was PC2-5300 but that the PC2-6400 was backwardly compatible......I noted that on my laptop it says Dual channels, the kids laptop says single channel.
Is that the problem?
I put the 2gb ddr2 into my dell (and it upgraded nicely from 3gb to 4gb - i swapped out a "wonner"). So I am sure the chip works fine.
And why did speccy lie!?!??!?!!? Both laptops are running with Vista.
thanks for any advice, chums.
