I would like to add some RAM to my laptop but I have one small problem: I would like to know what is the fastest speed I can put inside it.

I know from CPU-Z that I use DDR3 RAM:

One piece of RAM is PC3-10700 (667 Mhz) and the other is PC3-8500F (533 Mhz)

I use Acer Travel Mate 5742G if that's relevant. My Chipset is Intel Havendale/Clarkdale Host Bridge.

You laptop will take up to 8GB and the fastest speed it will take is DDR3 PC3-10600 . You can buy it here >>

By googling the model number of your laptop along with the word ram, this will then bring up hundreds of websites listing the spec of ram the computer takes, the fastest, max allowed, pin number etc etc. All the info is on the left hand side of the link above. Memory: DDR3 PC3-10600, DDR3 PC3-8500 Memory Type: DDR3 PC3-10600, DDR3 PC3-8500, DDR3 (non-ECC) Maximum Memory: 8GB Slots: 2 Each memory slot can hold DDR3 PC3-10600, DDR3 PC3-8500 with a maximum of 4GB per slot – Iain Simpson Jan 26 '12 at 13:23

You can put a faster ram, it will just run at a slower speed. I’ve had once some 133MHz SDR sticks running at 100MHz.

True, even with the very latest memory. But one should always check the "compatibility" informations. It happens that one stick will run, and the other won't. – Shiki Jan 26 '12 at 12:50
