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

[Amurtigress]

Hello! i have a P5Q3 Delux Q9550

and with this settings:

vcore: 1.40
CPU GTL freq 0/2: 0.620
CPU GTL freq 1/3: 0.620
vPll: 1.60
FSB Term: 1.46
Vdram: 2.10
Vnb: 1.40
GTL NB: 0.620
vSB: 1.10
PCie: 1.50

so i have a 45m can some one please help with GTLs, because i tried the mat but it doesnt work i can start but doesnt pass Orthos...

with math i change bouth CPU GPLs or only the one 0.670 (cpu gtl 1/3)?
i do i calculat the value?

tks

Hi,

I've got the P5Q3 Del. myself and a Q9300. Some of your voltages are off, tho, you don't even mention your FSB clock.

1) The Northbridge's ideal voltage lies around 1.26-1.32V between FSB 400 and 500. 1.4 has always been unstable for me no matter what the FSB clock was.

2) FSB Term.: Part of the 45 nm quadcores feels well around 1.34-1.38V. The rest usually lies quite a bit below. Keep this above VCore to reduce the risk of killing your processor.

3) GTL References. To my experience they should be around 0.67-0.69. My GTL Ref. 0/2 is at 0.69, GTL Ref 1/3 is around 0.67

4) VCore is definetly too high unless you are pushing your chip to FSB 600 MHz, which is basically impossible with quads on this board. Keep it around 1.3V for FSB 460. The board usually hits a FSB wall at 470.

5) DDR3 RAM on this board usually requires a tRRD timing of 8-10 while ASUS defaults to 5. And a tRFC of 82 or higher. Default is 60.

6) Try setting the PCIe frequency from 100 to 101. this improved my system's stability greatly, but might not have any effect on other setups. Many have tried it ever since the P965 boards like the P5B.

Hope that helps
