Yes they seem high but the real (in Windows) voltage is muuuuuch less than what it is in BIOS. If 1.5v in the BIOS equates to 1.4v load in Windows then I guess its OK to set the vCore high in the BIOS...

it would be fine under load, but if you comp stays idle all the time, the real voltage is @ 1.4V

Yea and most peoples comps (crunchers aside) are closer to idle most of the time but it's generally recognized that 1.45v is the maximum safe voltage for 45nms so I guess as long as the idle voltage is below 1.45v it's all good... I'm Priming right now at 500x8 cause blee1149 suggested that the slightly lower multi might be easier to stabilize.

I noticed something strange while reading a UD3P thread at TweakTown. In the 5th post there is a BIOS template for the board and in this template there is a CPU Reference and a CPU Reference 2 which I assume are talking about GTL voltage references. My board only has one CPU Reference setting! On my last board this chip needed different GTL settings for GTL 1 and GTL 2 so essentially now I have no way of changing those 2 settings independently....

My board is also missing some other BIOS settings (C2/C2E State Support, C4/C4E State Support) in the Advanced BIOS Features section. Are these missing because I'm running a beta BIOS or something? Do you guys have them?

I noticed that too but I thought people were just incorrectly copy and pasting the template from another EP45-type board and didn't think much of it. I didn't see any of those when I was using F7a either.

you guys recommend flashing the bios to the new F7 or leaving the original one? Ill be having this board installed soon and needed to know that much. Thanks

arjo_reich

Yes, for two reasons...

#1. because it shaves 7-10 seconds off the ACHI BIOS booting, should you enable it.

#2. because it's a beta bios and we need to give them our feedback as quickly as possible so they can make the required stable improvements to our new Rev.1.0 board. And you want to be "a good helper, right?" lol. Seriously though, it's how the boards become more stable and you're already qualified as an "enthusiast" by means of having to learn how it works to overclock it anyways...

sounds good to me so will do that before installing the OS, dont think i will enable the ACHI since i only have one HDD and i don't really raid. Where do i give the feedback? Thanks
I just went to gigabytes site and only found Bios F6 where is F7
Another thing i checked out their supported ram and G skill is not listed is it not supported or is it because they couldn't put a huge list there?

I use GSkill ram with my UD3P mobo with no problems. This is the one that I use:

G.SKILL 4gb (2x2gb) DDR2-1000(PC2 8000), model F2-8000CL5D-4GBPQ
