How to set up GTL Ref Values for 45nm & 65nm

[CryptiK]

Yes the higher you set the multiplier the higher the Vref you will get. To start with, set them both to 0.635x and work from there. I have found with both my dual cores they like the address bus GTL Ref (the second GTL Ref on your board) to be a little higher than the data bus GTL Ref, so you could set 0.635x and 0.655x for example. Test for general stability gains at several setting, and find the most stable setup for the given FSB & vFSB. I'm now running on my M2F 1.25 vFSB and the equivalent of about 0.690x and 0.70x on your board, it helped to stabilize my current clock.

Mikey, I have to agree with you about fine tuning with IBT, it's quite effective. The times & GFlops are very close and consistent when tuned correctly. I have noticed that the first iteration is always a little lower & takes longer though, this is not due to speedstep delay I have that disabled. This run isnt perfect but its pretty close:

Thank you Cryptik

At the moment i am running Both GTL's in Auto and NB GTL Auto but i want to get them manually to see if i can decrease a little Vcore and some other(if this was possible).

At the moment i am Running the CPU 420x10 RS 15 Passes of IBT.
I tried also 430x10 RS 15 Passes of IBT and 500x8.5 RS 15 Passes IBT.
Maybe i can play a little more to get higher FSB using a smaller multiplier.
The memories i have work very good the for the things i do, Crucial Ballistix Tracer Led Pc6400 @ 560Mhz with only 2.08V measured with Tester on the Board.

I will let you know when i make some tests these days.


Thank you.
Vincent

Agree with both of you guys, i tuned my GTLS (Thanks CryptiK ) and my runs are very close now

Sigh...Another problem...IBT Pass 20 runs that fails ORTHOS Large FFTs P9 in minutes...really disappointed and lost

Try MemTest86+ V2.11 to test your Memory. If you can pass test 5 without errors you won't have any problems with the Memory.
