**OFFICIAL Gigabyte UD3 P45 Yorkfield (45nm Quads) OC and Discussion Thread**

[nugzo]

These New Gigabyte UD3 boards are awesome. I've had a hard time finding info and settings for Yorkfields though.
This thread should be reserved for Quad discussion. 45nm Yorkfields is the goal but 65nm are welcome.
Since 500FSB seems easy for quads on this board, i cant wait for some more results with Q9450's and Q9550's.

I've had this board up and running an hour. I previously had 2-Striker 2 Formulas, 1-MSI P7N diamond, 1-EVGA 780 FTW,
2- Maximus 2 formulas and 1- Rampage Extreme.My goal was a Q9650 4500Mhz 500x9 on Air. None of the other boards could do it.
Closest stable was 490x9 with the MIIF. I've only had 1 BSOD with this board and it only took an hour for the beginnings of an oustanding OC session.
This is what i call FUN! I've booted into windows at 533X8 only to get my 1 and only BSOD after 10-15 seconds.
That was with no extra voltage over what i'm running now. I'll be checking for max FSB Next.

Thanks to napalm for some bios settings.

I'll post a template in a few minutes.





***************************UPDATE***************** ******* 02/04/2009 These are my current 24/7 settings. 4410mhz, 8gb ddr2 @ 980mhz, GTX 295 22,000 in 3dmark06 and 23,000 in Vantage.

Here are my updated settings. My original post i didnt have gtls tweaked yet. I was able to drop all voltages.. The few minutes of Prime showing isn't for stability, just to show load temps. I am 12+ hours Small and blend stable with these settings.
