X48 Rampage Formula Preview.

This thread is soooo long, anybody can tell me what is average FSB with E8000 series? It is possible to hit 620-630 easly (like Rampage Extreme)?

BIOS 0803 is the most stable BIOS available for my system.

IntelBurnTest 25 passes and 6 Hours Prime95 + Unreal Tournament 2004 stable.

Here's a screen shot with tREF at 4352T. The GFlops are a little higher, with tREF 4352T for 1117MHz than with tREF at 3120T set by the BIOS, as expected.

How do you figure out what tref you need to set??

7800/(1000/DRAM)

Example: 800MHz -> 7800/(1000/400MHz)=3120 -> 3120T

Ok, i didnt get that at all..

I'm runnin 8gb, currently at 3.7 on the proc, 1108 on the mem, so how do i "cipher" it out???

7800/(1000/554)=4321 -> 4321T is the tREF that you can use for 1108MHz

where did you got memset with that tref values ?

I didn't, it's MemSet Version 4. I used Bar_Edit to change the tREF timing and MemSet to verify that the timing is right.

OK thanks, now one question more

I tryed to figure out what registers to change, but a lof of different registers change in bar_edit when you change tref timing with memset, is there anywhere written what register is for what?

I've got this from mikeyakame.

The registers you need to change are: FED14260 08 and FED14660 08

See the screen shots. It's for changing tREF from 3120T for 800MHz to 4352T for 1117MHz.
