I've read some reviews on newegg and since the P6TD is only 2.5 months old, I'm not getting a lot of experience with it but for the P6T Deluxe V2 there is more info and these are extremely similar to each other.
since the reviews for people with the Deluxe V2 are getting it run at he listed specs of 7-7-7-24 at 1600 with a 1.64/1.65 voltage.
I only plan on running it at the listed 1600 spec so I don't feel the need to get corsair dominators. I did look at Corsair XMS3 line though. The problem is the memory compatibility sheet for the P6TD is really small, but this OCZ memory is listed for the Deluxe V2, I believe.
I will be setting up my whole computer tomorrow. If you can wait I will post back. but, here is the link that I suggest you follow prior to making memory Purchase: http://www.asus.com/product.aspx?P_ID=iRlP8RG9han6saZx
scroll to, "Memory Supported List" and there is two PDF's, click on the more recent one.
