Best memory for Asus Rampage 3 Formula

[thegreatgatsby1]

Hey guys i have a question, will this memory work on my asus rampage 3 formula board:Corsair XMS3 CMX6GX3M3A2000C9 6GB 3X2GB DDR3-2000 CL9-9-9-24 1T Core i7 Triple Channel Memory Kit.
Its on this website:http://ncix.com/products/index.php?sku=53609

Also i was thinking of getting this memory if the other one doesnt work:Kingston HyperX T1 Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 2133 Desktop Memory Model KHX2133C9AD3T1K2/4GX
Its on this website:http://www.newegg.ca/Product/Product.aspx?Item=N82E16820104204

If both of these are compatable which one would be better to get? One is a 2133 and the other is a 2000 but one is a 6 GB while the other comes only in 4 GB..i am confused as to go for 6GB one or go for the faster one?

In case you guys are wondering my specs:
Asus rampage 3 formula mobo
2 X 570 SLI
2 gb kingston 1033 memory (right now)
HafX case
intel 950 3.7 ghz

Thanks and if need more info id be happy to provide!

Performance scaling at anything above 1600 isn't much impressive, a low latency 1600 kit will give you better performance in most cases at a much better price.

Avoid 2x2gb kits for your rig, you'd be wasting the tri-channel capacity of your i7.

^well said.. Also look out for memory modules with even timings like 8-8-8-24 .. A 6GB kit (3 x 2GB) will be good..

Of the two you have listed I would go for the Corsair. I have that kit in mine and it does well and I like the low profile of the ram which won't interfere with large heat sinks.

Before I got the Corsair kit I tried a 1600 cas6 Mushkin set of low latency ram that wouldn't run stable at 1600 or above no matter the timings. So I looked at the QVL list for the board and the Cosair was listed. It will run 1750 or so cas8 with decent voltages (qpi/vtt under 1.4) and rated voltage for the ram. The thing with the high speed ram they don't tell you is at what qpi/vtt it needs to run that speed which can be as high as the ram itself which is too high for me to feel safe for 24/7 use.

Here is a hot of the Everest memory bench at 1725

and a shot of it installed and under my VX.

Thank you all three of you for answering and clearing up my question. All three of you guys had something to add and for that thank you. I will choose wiini for the best answer since he was first but again thanks to all three of you guys. I now know exactly what to get and far less cheaper too!
