Don't expect much more than spec, they are still binning old stock, I notice the kits going in and out of stock a lot. I think if they can get a kit to do 1001 7-7-7-20 1T 1.65v they will probably sell it as a 2000 C7 kit. It just depends on luck I guess. My 2200 C8's are not great at all. ~1700 CL6 @ 1.7v. I was able to do 7-7-7 up to 1900 though, but then I run into IMC problems.
