How can i know the RAM speed of my laptop?

it's an Asus K40IN-VX128

How do I make sure if the frequency is 667MHz or 800MHz, I was thinking of an upgrade.

I've never seen a "this comment was edited" doohickey before! Ooooh comment editing happened. My mistake :3 – Phoshi Dec 30 '09 at 14:20

Use CPU-Z, assuming you're on Windows.

I used this CPU-Z and it clocked my RAM frequency at 398.7 Mhz. So it didn't work for me. – elcool Feb 20 at 3:36
What RAM do you have? – CodeByMoonlight Feb 20 at 7:55

A list of RAM benchmarking tools is available at http://www.benchmarkhq.ru/english.html?/be_memory.html There are a lot of freeware tools there.

one of the easiest places ive found to get this information is

www.crucial.com/uk you can select by manufacturer / make / model etc. failing that they have a downloadable tool that will scan the PC and work it out for you.

all nice and easy. they will even recommend the best sets of ram to upgrade to and how much they can provide it for.

sorry sounds like a bit of a plug for them but hey ho there a good company that get it right!

Unfortunately this doesn't give the speed. – Gnoupi Dec 30 '09 at 14:59

Try with SIW - System Information for Windows.

Maybe this one will work. (I'm still quite surprised CPU-Z didn't show memory information)

CPU-Z shows it here, on the memory and SPD tabs. DRAM frequency, channels, latency, etc. – CodeByMoonlight Dec 30 '09 at 16:59
I know it does, it does for me as well, but the OP said it wasn't working on his computer, for a reason I can't figure out. – Gnoupi Dec 30 '09 at 17:36

If you're planning on adding hardware to a machine, then it sounds like you shouldn't be afraid of a screwdriver.

Open up the flap on the bottom of the laptop and have a look at what RAM is already in there.

1) it will almost certainly have a sticker on it telling you what speed/size is currently installed.

2) It should be obvious if you have a spare ram socket (to upgrade) or whether you will have to remove what is already there and replace it with something larger.

Hope this helps.
