I'm beginning to think it's better to look for 800-45s that can go real high, because they are compatible with both the P4T-E and TH7II no problemo. I hear some people with TH7IIs can't run PC1066 stably, even after tricking the board into using them.
So far, looks like the Kingston PC1066 is only doing around 142-144/4X. Same with the Mushkin E/S PC1066 (I suspect those are reject sticks). The jury's out on the Mushkin PC1066-32 since they aren't available yet.
Heck, I got two 256 MB 800-45s that will do 140/4X. I also have half a dozen 128 MB 800-45s that will pass Memtest all night at 148/4X. And I'm talking four 128 MB sticks running together. I haven't even tested them in pairs since 256 MB ram is too little for gaming, IMO. Problem is when you run them in an OS, have to drop them down to 145-146/4X.
Also it's true what Batboy said. If you got a TH7II, it's a moot point getting PC1200 since you won't touch that. Some people claim 144/4X on the board but that is only PC1152. A majority of people run 3X and even at 180 FSB, all you need is 3X180=540x2=PC1080. All you need is stuff that can do 135/4X.
The P4T-E is a different matter with the -13 DRCGs. I'm currently running 156/3X or 145/4X on mine, so I am looking for stuff that will do 156/4X, since the CPU on that board maxes out at 160 FSB.
At 145/4X, I do get 3616/3610 bandwidth though
