Correct memory for Dell?

[suomi]

After sound advice from members on here I purchased a Dell XPS 17 (L702x), and am loving it.

I am looking at dropping in an extra 8GB of memory, to bring it up to 16.

I wonder those that have done this what did you use?

Have seen this and it looks ok http://www.overclockers.co.uk/showproduct.php?prodid=MY-154-CR&groupid=701&catid=8&subcat=1264 but am unsure on the voltage is 1.5v ok? as have had suggested also 1.35v.

Would I see any differnces from 10600 to 12800 memory?

Thanks for any help or advice anyone can give.

Thanks guys this is really helpful. Looks like I will go for the 12800 memory as I tend to do a fair bit of panoramas and and HDR which can drag things down (and the extra cost does not seem to bad).

I had ran previously ran Crucial memory scan which had showed 4 slots, and had had the back off and a quick look and things seemed right.

But after the comments here, I took the back off again, and sure enough there is infact 2 slots. The ones underneath are dumbies, with a thicker post than the memory notch is. So an expensive mistake avoided.
