Asus - P8Z68-V LE memory pairing suggestions

[droorda]

Hello all,

I'm in the process of upgrading my old q6600 system to a i5 2500k.

I've picked out this board to accompany the I5
http://www.bestbuy.com/site/Asus+-+P8Z68-V+LE+Desktop+Motherboard+-+Intel+Z68+Express+Chipset+-+Socket+H2+LGA-1155/4642158.p?skuId=4642158&productCategoryId=abcat0507008&id=1218500950417


Now my question is the best memory options. I know the board supports above ddr3 1600, but next to the specs it says (OC). I'm assuming that means if i bought, say some 1866 memory, it would only register initially at 1600 and I would have to overclock to hit 1866? I'm mostly going to be using this computer for some gaming and a good amount of video rendering with adobe after effects and sony vegas.

Here's a few that I've been looking at.

Corsair - Vengeance 4x 4GB =16gb @ 1600

Corsair - Vengeance 12GB 3x4 @ 2000 (118$)

Corsair - Vengeance 16GB 4x4gb @ 1866

Corsair - XMS3 4x4 @1600

and lastly

Kingston HyperX Genesis 16gb 4x4gb @ 1866

All things considered, I thought the 12gb of 2000MHz looked the most appealing, but since it's only 3 sticks will I run into performance issues with pairing ram? any advice here would be greatly appreciated.

also, as far as the motherboard goes and it's onboard gfx, I read about the idle/load graphics switching decreasing render times, would this apply to rendering videos? (don't really think this is a huge deal, but I'd like to stick with an asus board, had some bad experiences with MSI/gigabyte. any other board suggestions welcome)

Well if you want ram that matches you Motherboard.... Kingston is beast. If you want High performance, with high profile heatsinks and don't plan on adding a bulky After Market cooler for your CPU. the Vengence is a best choice. But if you want to add extra like a After Market heatsink. the Kinkgston kit will work best. XMS 3 is ok ram but i would get the Kingston over XMS

understandable, but that doesn't really answer my question about using a 3x or 4x stick setup, or my question about the MHz

bump. still could use some advice.
