View Full Version : Adding new RAM to G55 - Question

02-05-2013, 04:11 AM
Hey all,

Long time lurker, first time poster. Just had a quick question and needed a few opinions on some RAM I am wanting to add to my G55VW.

I am wanting to top up my RAM to 16GB from my 12 I already have and was looking to add a 4GB G.Skill stick to it (found here: http://www.newegg.ca/Product/Product.aspx?Item=N82E16820231481).

I checked everything over and it seems to match up to my stock RAM (see below for the HWiNFO64 report). Does it look like this RAM will correctly work?

Do I need to buy matching pairs for any specific reason, or will just adding this one stick work properly?

Also, I was hoping to get a few opinions on G.Skill RAM. I have read some good things about them and was wondering if anyone had any experiences to share?

Thanks a bunch guys!

yep, it is work, did you meet any problem in use?

Nope! Just more or less wanted to know about any possible compatibility issues that I should be aware of before I purchase it.

yes, it will work. make sure you install the ram properly. check out the video for proper ram installation (http://rog.asus.com/forum/showthread.php?23929-Adding-RAM-to-G75&p=168646&viewfull=1#post168646) if you are not sure.
