Hey guys I have a small question about if the ram I'm looking to buy will be compatible with my motherboard.

My mainboard is an EVGA P55 E655 SLI board & right now I'm running 6GB (3x2GB) of Samsung DDR3 1333 (PC3-10700) cheap I know, that's why I'm looking to upgrade :) 

I'm looking at buying a G.Skill Sniper 8GB (2x4GB) matching kit of DDR3 1333 (PC3-10666) but I don't know if it will work with my motherboard & need a little assistance.

Also if you know any other good quality ram suggestions for 8GB kits that are in the same price range as the G.Skill Snipers feel free to let me know

Oh, the model is: F3-10666CL9D-8GBSR

Thanks for your help guys ;)

I bought a custom made gaming PC about a year ago & it came with the 6GB of Samsung ram.

Since I bought the PC I have upgraded the 2 GTX 260's that it came with to 2 GTX 560 TI SOC cards from Gigabyte & also added the Coolermaster Hyper 212 plus heatsink & I'm now looking at upgrading the Ram to some good quality parts.

haha, whoever built the custom rig didn't really know what they were doing... triple channel ram in a dual channel MB...

Yes, the G-Skills are what you need, and will work great!

1x,2x,3x,4x will ALL WORK; you lose Dual Channel with odd slots or unequal GB/Channel or ~1% performance hit from broken Dual Channel with DDR3. Samsung isn't cheap RAM, they produce 'Full Spec' OEM and server memory and it's as good as anything.

edit: the builder might have done you a favor if the price of 2x2GB and 3x2GB were closely priced - MORE GB WINS!

Sure the F3-10666CL9D-8GBSR will work, but IF your CPU is faster than 2.66GHz then I would get DDR3-1600 before a more less side grade to G.SKILL any better performance will be solely from the +2GB and nothing else or 0%~2% increase.



IF you still have any 'Free' memory listed when you 'play' a game then you'll see a 0% improvement in FPS, but the typical 6GB vs 8GB is 0%~1% depending upon the game; see http://www.tomshardware.com/reviews/ram-memory-upgrade,... The increase is in keeping the 'Shared system memory' FULL to the GPU and its' maximum value e.g. -> http://i1013.photobucket.com/albums/af254/Jaquith/WEI_H...

Thanks for the info, although I'm not 100% sure what some of the info above means I get what your saying.

I'm not looking to OC the ram, I would just like to add some better ram that will last awhile and I've read that the G.Skill Snipers are a good pick.

Thanks for the help guys I appreciate it
