My Dell Latitude 3540 laptops won't accept new RAM

[brat02]

yeap two faulty memory sticks.... the 3rd one works just fine, thanks for all your replies

Could be a dodgy ram slot. Have you tried the ram you bought on eBay in the slot that had the original ram installed? And have you tried your original stick that's known working, in the second slot?

I won a mini-PC a few months back that NEEDED 1333mhz sodimms. 1600mhz wasn't recognised at all.

Double check the specs.

Does it need some BIOS tweak for the RAM timing, or something like that?

Sounds like two dead sticks of ram if you've tried them independently.

Time to raise refund requests.

Not sure I ever trust 2nd hand ram that mush - is the price difference from new worth it?

Hi all,

I have Dell Latitude 3540 with 4GB of RAM and want to upgrade it to 8GB but when I try to install 2nd stick of 4 GB my laptop won't boot( no POST screen either ) , it sounds like it keeps trying to switch on but fails.

I have bought 2 sticks of RAM from different ebay sellers but it just does the same thing.

I have tried these RAM I bought on it's own in my laptop and with one of them it takes ages to go to desktop, with second stick on it's own it just won't boot up at all.

The memory is correct as far as I can tell and the same manufacture( btw my Dell laptop has Kingston RAM for some reason )...... any ideas why this is happening?
