X48 Rampage Formula Preview.

hi there lads, im not an actual RF owner, but i do have its bios modded to my P5E bios is RF0410. ok, so straight to the point... i was just wondering how i could set tREF values in bios instead of having to set them with MemSet 3.4 in windows. any clues? i thought that extreme tweaker was the right setting to do the trick, but the other day i proved myself wrong... the strange thing is that when i had my SuperTalent (cheap ass) memory, i allways had tREF at 16383T while on "Stronger" extreme tweaker setting.. but now, with my g.skill set i find that i would only get 3120T when in OS. "strange" i thought, "but hey, dont give up!" and so i ended up here...

many thanks in advance for any piece of advice anybody can provide

It isn't possible to change tREF in the BIOS. You have to use MemSet for that. I hope Felix add auto tREF for the ASUS Rampage Formula X48 Chipset.
Mikeyakame already gave him some code to make it easier for him.

ASUS should definitely add it to the BIOS that it sets tREF timing for the memory speed you are using.

Let's see what they have to say about it. They are going to run some tests to find out what should be done to fix the issues with BIOS 0802.
