Mixing memory sizes

sWiZzLe · 18 Apr 2007 at 06:00

Whenever I've bought memory, I've always bought the same type and same size.
Now I've got a laptop with 512mb, but my fx card takes up 256 of it.
Can i stick in say, and extra 1 or 2gb

Also, how can i find out what my memory is with regards to 2100, 2700, 3200 - is that speed or something?

On the site where i bought the laptop the memory spec says the following:
512MB of DDR2 533/667 MHz memory, upgradeable to 4 GB4 using two soDIMM modules (dual-channel support)

Cheers

It's possible but not advisable. And, unfortunately, the only way to know for sure is to install and test which means you have to buy it first unless you buy local instead of online.

Have you tried using CPU-Z to find out what your RAM is rated at?

If the laptop supports dual channel memory then the chances are both sodimm slots are occupied with 2*256Mb TBH, unless it has 4 slots.

So either get a 2*512 or 2*1Gb sodimm kit.

I always assumed that only one slot was occupied - mainly as i could've got an extra 512mb when i bought the laptop. But at the time couldn't afford to. Anyway i opened up the laptop and there is a slot free.

Then a ran CPU-Z <-Thanks for that, and realised it didnt need to open it up

Max Bandwidth: PC2-4300, so assume 4200 is the memory i am looking for!

£35 quid for 1gb of Corsair

Excellent, think ill just buy one of those, and if doesnt work with the 512, well then ill buy another gig at some point.

Thanks
