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

[vox]

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

I have bios 1406 can boot and run Orthos for 10mts.

Just for bench i can make 8.5x500!!!

What adjustments do think i can make here?

tks
