Picked up my QuadGT last saturday (my first ever C2D setup ).
Removed the heatsinks, cleaned things up and applied AS5 on NB and SB. Putted a tiny little bit of Arctic Ceramique on the 5 PWM's, but left the TIM on it (read somewhere that eva2000 did the same thing and got pretty decent temps from the PWM's)

It came with bios v 1.0 and I had big problems getting this board to work properly.
It wouldn't boot from my HD nor from a bootable XP cd.

I re-read this thread and decided to flash to bios 1.1.
So far, so good.
I had a recent Xp install, from which I removed the Nvidia drivers, cleaned the registry. So I decided to reboot. All went fine, necessary Intel drivers were installed.

Can't say that much about performance, still learning and figuring out the board and memory (Crucial Ballistix PC8000), games etc.. will be for later.

Did a quick test on my Xeon 3050. Seems to do 3400Mhz nicely at 1.33-1.34V, watercooled.
The PWM's got very hot, about 75-76°C under load. So I put a 60mm fan, and it keeps temps in the low 40's. Much better.

Anyone has good tips for my Ballistix sticks for running over 500Mhz?
I have them running at 425Mhz, 1:1, 4-4-4-12 with 2.00V (I know they're rated for 2.2V), but I'd like to have a stable 24/7 settings, without the risk of burning them, due to too much volts on them.
Thanks.
