Maximum PC

I'm planning a ASUS MAXIMUS IV EXTREME (REV 3.0) with a i7-2600K and maybe 2 of these ASUS EAH6950/2DI2S/2GD5 Radeon HD 6950 2GB for my build. Will be using W7. Thanks in advance.

I need some memory advice. 4GB or 8GB or more?

Also, what specifically should I get?

G.SKILL PIS Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 2200 (PC3 17600) Desktop Memory Model F3-17600CL7D-4GBPIS $149.99

or

G.SKILL Ripjaws X + Turbulence II Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 2133 (PC3 17000) Desktop Memory Model F3-17000CL9D-8GBXLD $199.99

What is the reason for the build in general? What is your ultimate goal?
If you are just gaming 4GB will be fine if you want more than 8GB will do but more than that you probably won't need. if you are looking for fast memory than try this @ 8GB http://www.newegg.com/Product/Product.a ... 6820231459
Also:
Both are 4GB sets of Dual channel gaming memory!

For a socket 1155 processor you do not want to exceed DDR3 voltage beyond 1.5V.

Thanks for the input.

That maybe true but 1.65V will run in it just fine!

Sometimes the boards are picky with voltages... I would go with Corsair XMS they are rock solid.

i'll post as i have recent experience with ASUS sandy bridge and its finicky RAM approvals. i bought two kits that should have worked according to Kingston's site but the 8gb versions (16gb total) weren't on ASUS' QVL. according to the ASUS forums there are multiple problems around RAM not listed on the .pdf linked below. if you have any intentions of OC'ing that CPU (and with the mobo selection i'd assume that's a yes) do yourself a favor and get a flavor of RAM specifically listed.

also, at this time, try and stay away from 4 sticks. i'd definitely suggest 8gb (2x4gb). you can find a great selection at around $100.

and lastly, there are also a lot of headaches with RAM speeds past 1600mhz settings - so, i'd not worry about DDR2000.

good luck,

Yup, and the onboard memory controller in the CPU will burn out.

I will agree that some boards are picky but I have the Asus P8P67 Deluxe and it looks as though, per the QVL, that it can handle up to 2.0v memory so the best answer is do the homework and look at the QVL for the board you have or will get since it is tested to work.
