So, I want to upgrade the memory in my HP pavilion (dm4 series) and I narrowed it down to these two kits. The only problem is, I have no clue which one I want... I know lower cl is better for gamin (which I do quite often) but higher mhz wouldn't hurt either. Which package should I choose for better performance? Or if you think both are bad, what would you recommend me to get?


Module Size: 8GB Kit (4GBx2)
Package: 204-pin SODIMM
Feature: DDR3 PC3-10600
Specs: DDR3 PC3-10600 • CL=9 • Unbuffered • NON-ECC • DDR3-1333 • 1.35V • 512Meg x 64 •

According to this:

http://www.crucial.com/store/listparts.aspx?model=Pavil...(Intel%20DDR3)&Cat=RAM

Either should be fine. It appears your laptop supports 1.35 and 1.5V.

I would go with the CL=7 version though that you listed. It doesnt provde as much bandwidth as the first set you listed, but should talk to your processor a bit quicker due to the lower timings.

Although the crucial website reccomends the first one ram set you mentioned (with similar timings and voltage).

With DDR3 RAM the frequency and latency mean almost nothing in performance so buy whichever one is cheapest.

so there would be no noticeable difference?
