Since the board went back to bios F2 the board must of switched to the second bios chip for some reason,doesn't the ud7 have dual bios.

Yeah it is dual bios. How does that work exactly and what does it mean if it goes to the second bios chip? Does it mean the first one is corrupted or something?

Currently in windows with my i7 930 at 4465 with 235blck

Yes, that's what it means. A BIOS has a checksum stored in it that is being compared with a checksum calculated on the fly upon POSTing. That way the board's BIOS' integrity is being verified.

However that does not always mean the first BIOS is REALLY corrupted if the checksums don't match. Usually it just means the system was very unstable and thus generated a wrong checksum. I've had such fallbacks on my ASUS P6T Del. V2, but since there's no such secondary BIOS, it would rather ask me to insert a USB stick/CDROM with a BIOS image file to restore it.

What could be causing cold boot issue?
Sometime when I fresh start PC, it will fail to post and shows the OC failure message. I just go in bios and save and exit and after it boots fine.
Anyone experienced same problem? what could be the cause? The PC is stable in windows, linx, prime and gaming.

Happens to me a few time. I had more of it with F6, slightly better with F7. Probably a bios issue.

I read that EuP can cause that so I enabled it, also I bumped 1 notch more on vcore and qpi/vtt ... will report back if it fix the post issue.
What QPI/VTT you are using @ 200bclkx21?

[NoGuru]

Just bought a UD7 today so I wanted to say "HI" and sub to this thread. And I should not be reading this at work.

and neither should I


Good luck overclocking.

I doubt that EuP could help. What bios do you use? Try disabling USB keyboard/mouse support.

Congr, good choice. Is it rev 2 or rev1? Please post your experience when you put it under run.

Thanks. Not sure, it's not here yet. I will let you know when it gets here.

Congrats, and welcome to the thread.

what CPU did u get with it?

Congrats, and welcome to the thread.

Thanks, bro. Can't wait to do some benching with you guys.

what CPU did u get with it?

No CPU yet, looking for the right one. This task seems to be harder then finding a good wife.

[radaja]

man im a little bummed because i got the UD5.but it will do

[NoGuru]

Basically the same thing. You got any good 920's?

[Dahaka]

Guys, how goes this MB with LN2 and 980x?, any suggestion before benching? tips and stuff like that i will apreciate a lot

[radaja]

Basically the same thing. You got any good 920's?

yep,and the giant air HS
no i only have the one 3849B018 right now,testing it out and looking for more
in the meantime.so far its pretty good but not as good as my first 3949B018 one.

EDIT:got to say though these gigabyte boards are so consistent from board to board
and model to model.i put in my settings for 21x200@4200 1600 6-6-6-20 1t from my
ud3r and worked perfectly.same thing with my three ud3r's and three different cpu's.
its easy to help others also with settings.the ud5 seems to be very solid so far

[NoGuru]

AHH, Micro Center just had a few 920's in stock for $169 and I missed it.

[radaja]

oh man that sucks big time,169 is an awesome deal.
you could buy a few and test them for the best one at that price

[MadHacker]

Quick question...
is there anyway to control the fans from the MB fan headers?
I have 1 fan in my system, and i can still hear it.
when my machine is idle i want it to shut off, but when my machine goes into 100% CPU load it would be nice that it turned on.

Hard to beat the deals from microcenter on these i7 cpu's. My best clocking i7 also happens to be the cheapest, 179.00 for an i7-920 at microcenter several months ago, sorry to see them go away.

[NoGuru]

And you can only buy one per household. Maybe by a small chance they will get them one more time. I will check every day now.

Any mods for this board?

my closest microcenter doesn't really care for the one per household, as I was able to buy three 930's a few months ago.
