New Memory Tweaker for Intel Chipsets

[Don_Dan]

...where do you get these informations? Is this 1.33 multi is permanent?
I did not find anything in the intel datasheet.

I just said this because it's my experience from what I've seen/read:
SB can do 1:3,1:4,1:5,1:6,1:7,1:8 and 1:9 on ES chips, but the real memory frequency is always *1.33.
IB can do 1:3 to 1:13, and you can choose 100:100 or 100:133 leaving you with a lot more options for choosing memory speed.

But is this 1.33x also when using sandy on Z77? (did have 1 more option then I had at z68, 2400ddr, but ofcourse it won't boot)

ed: thought the 1.33x was an Ivy thing...

I don't know about this, I've seen a few guys running IB on Z68, but no one so far running SB on Z77.
The divider for 1200MHz memory speed on SB was only available on ES chips.
