Long time reader first time poster.
Hi guys I have the GA-P35-DQ6 board and I love it for how COOL the PWM runs under load 1.58 Vcore. Though I've replaced the thermal pads with AS5 on NB and Ceramique on PWM area and SB.
It holds my Q6600 G0 overclock at 3.75GHz pretty nicely.
But as you all know this board has one BIG problem with PCI-E X16 port falling back to x1 randomly. I have tried upping the PCI-E Voltage up to +0.3 and setting PCI-E Frerq. between 100-115.
No matter what setting I choose it falls back to X1 after a reboot or changing the boot device in bios and 99% of the times I have to power down the system and literally pull out the graphics card and reseat it to get the full X16 bandwidth back again.
Anyone out there knows precisely how to tackle this problem?
Here is more info on my system/setting:
P35-DQ6 rev1.0 BIOS F5
Q6600G0
VCore1.587
VDimm +.35
PCI-E V:Tried +.05 up to +.3
FSB V: 0.35
MCH V: +0.3
417x9
I am pulling my hair out here.

I just want to stick with P35-DQ6 if possible (for as long as I can resist the urge to buy an I35 pro) as imo it has the coolest running cpu voltage components among all P35 boards wich I value more than the flaws it has like the lack of tRC setting for memory tweaking and non working EIST.
Any thoughts? Although I have tried different bios settings to tackle the PCI-E X1 issue before I am keeping my mind open and willing to start over if someone has any suggestions.
Thank you.
