This was the chip (before I RMA'd it)

Set to 1.3625 in bios with LLC enabled.

I don't recall which bios it was offhand. I ran the board (without LLC) for several months afterwards with a couple of different 45nm chips without issue.

Here are Jor3IBR's settings with a Q9650 using air ( Sunbeam Core Contact Freezer)
on this board.

He also set a world record with the board and a Q9650 (link on front page)

These setting can also be applied to a Q9550 as well.

1.376vcore, 1.400vtt, 1.57pll, 1.40vnb, 1.20vsb

RAM used was the Gskill 2x2 GB Pi 9600 series

Has anyone had luck running a UD3P with 4 x 2gb? I keep thinking I get it all running stable, shut it off for the night, and when I try to restart it the following morning, I get nothing. No post. I have to take a stick out, load defaults in the bios, reboot, redo my oc, then boot into windows. It's almost like it needs to warm up before it'll run overclocked! Once it boots, it's stable. P95 will run forever, etc.

Thoughts??

i have no issues but i decided to run only 2x2gb cause i will never need 8gb of ram so i put it in my secondary pc.

I'm running 2x2GB of memory with no issues. You just have to make sure that you don't overclock it and you'll be fine.

Heres my current 4.25gHz OC. Since it's stable and runs fine I'm thinkin about running it 24/7. Any opinions on that Vcore? It idles at 1.40V.

I need some suggestion on my system

E8400 + UD3P running best on overclock at 4GHz (800x5) with original cooler

It look like need some optimized and fine tune for stable.

Do you think CPU Vcore and CPU Termination is too high?

If I set lower it could not enter Windows

Doesn't sound like your memory is at fault there. Anyway I ran 4x2GB on this board with no problem.

Hej guys! Could you please advice me what to install for the subj mobo first of all after installation?
I installed only Network driver so I'm here not to ask you. Should I download latest drivers or use cd from the box? What about bios?
Shoud I install SATA driver for my HDD? EnergySaver?

elusiv1

Don't worry about the bios, download the latest drivers off the Gigabyte site... I'm running the stock F5 bios and it's stable as can be, no problems with voltages or any of that stuff...
