Hi, I have an HP Compaq nx6110 and I want to expand it's memory, it uses a DDR memory of 333Mhz, but I have an old memory useless, but it is DDR of 533Mhz, so, do I have any problem or which would be the problem if I use a DDR memory of a different Mhz???

Supposidly the 533mhz should slow down to 333mhz and be ok, but on my toshiba i did the exact same thing and it wouldn't turn on. I just removed the card and my laptop an it booted up fine. If you play around with the ram it wont damage your system, if it works it will turn on, if it doesnt it wont boot and you'll have to remove it.

Yeah, laptops can be real b*stards like that - I've run into issues with Lenovos where you just can't install third-party RAM even though it's fine according to the specs. The BIOS stops the boot sequence with non-authorised RAM installed.

Can you try before you buy the memory, to see if it'll work in your laptop?

Ok, so, it means that nothing is going to happen if I put it without be the right one, if it doesn't work just won't boot, I am right?

Either that, or you'll get a BIOS error message.

As always, take care when handling the memory... it's easy to bend pins or zap the circuits with static electricity. Don't ask me how I know that. :)

You should be fine.

I had a very unhappy chappy the other day as he was sold ddr2-667 instead of ddr2-533, the laptop would turn on, but the screen would not go.

Installed the correct ram, and away the laptop went, as happy as Larry.
