I'm a lot more useless at this stuff than I thought.

I had bluescreen issues a while back and eventually worked out that my RAM was corrupt.

I had a 2GB lying around so I downgraded from the 4GB that it came with and that solved my bluescreen problems.
I've got round to getting a new 4GB card so I popped that in the slot I had and put the 2GB in the spare slot. I've since found out that the laptop isn't reading the 2GB card and I have 4GB installed and 3.75 available as opposed to the 6GB I was expecting.

It's windows 7 64bit and as far as I was aware that meant the maximum I could have was 8GB. I've tried checking my settings at start-up but there is nothing to turn on memory remapping.
It's DDR3 RAM if that makes any difference :dunno:

Anyone any ideas?

Thanks.

If you have two cards of similar size you should be fine.
Two * 2gb or two * 4gb.

It's the mismatch that's the problem.

Maybe.

Never thought of that, mum has 4GB in hers, may steal it for a wee test. Cheers.
 
Never worked, still says the same thing.

I'm wondering if maybe the second port doesn't work? It doesn't work when I try to power the laptop using it on it's own, but I thought maybe it was a 'Primary' 'Secondary' type thing? But that could be complete nonsense.
 
Have you tried switching it off and switching it on again?

That's pretty infallible.

Well that's my IT knowledge exhausted.

Chuck it and buy a new one.

It's not even a year old, Packard Bell say it's outside it's warranty though, I went to them for help with the blue screen.
Not great for customer help.

Cheers anyway :thumbgrin

So... It kinda works now....

Mustn't have been seated properly the 400 times I've clipped it in, or there's a bent pin somewhere that just happens to be in place just now...

Case closed :thumbgrin

Google the specs of your motherboard as it may only support a certain amount of RAM.... I know on mine it only supports 4GB

could be your problem :)

PS

4GB is loads and you shouldnt need much more unless you are trying to multiscreen 8 screens of a certain product hehe
 
Hammi,

Windows 32bit (x86) versions can only use up to 4GB of RAM, anything above 4GB will not be usable. Windows 64 bit (x64) versions can use up to 192GB of RAM.

Basically is you have a 32bit versions of Windows running on your laptop you will only able able to see 3.75 GB no matter how much ram you have in your laptop.

hope this makes sense

It's okay guys, I got it last night, I either wasn't clipping it in properly or there's a bent pin that just happens to be connecting, up to 8GB now because I've stole my mums card, but after reading about RAM last night I realised it doesn't actually speed my laptop up, just lets me run more processes, quite gutted actually.

Cheers though :thumbgrin
