ASUS K53S, Upgrading RAM

[mrh1390]

Dear All,
I have an i7 ASUS K53S which originally came with one 4GB Elpida memory stick. As I discovered its website, standard PC3-10600 is manufactured by company.
CPU-Z gave me the following:
PC3-10700 (667) that is working @ 665.5MHz 9-9-9-24
Timing table: JEDEC #4 : (609 MHz) 8-8-8-22 tRC 30 @ 1.5V AND JEDEC #5 : (685 MHz) 9-9-9-25 tRC 34 @ 1.5V

Now, I'm going to upgrade to a dual channel 2x4GB, and have 3 Options: Kingstone, Geil and Patriot all 1333 CL9. I have no more information since the seller just know as much as I know about the modules!

Which one has more possibility to work in dual channel with that Elpida stick?

I appreciate your help.

Get one of the 1.5v brands; kingston or patriot. You'll have to try mixing the sticks. Be sure the memory setting is on auto in the bios. Can't guarantee all four will work together. Sometimes you get bluescreens when mixing ram brands. If you do, try the 8 gb kit and remove the elpida.

Match up the specs as closely as possible. I wouldn't mix, tbh. You probably won't have an issue, but DDR3 prices being what they are, I would just buy a new set and not worry about potential compatibility/performance issues.

8 gb is plenty so you can sell the elpida if needed without losing too much performance. I tried 16 gb but went back to 8 to save space on my ssd.

Thank you guys,
I've just bought the Patriot 4GB stick. It works fine along with the original Elpida in dual channel, timing 9-9-9-24 (665.5 MHz).
However, the memory performance increased to 7.6 (from 5.9) in WEI.
