**Gigabyte GA-X58A-UD7 OC-Tips-Bios-Discussion Thread**

I noticed 1.640v(bios) vdimm on this board fluctuates to much between 1.616v and 1.632v in PC Health status/ ET6 while when I set 1.660v(bios), it is steady 1.648v and doesn't fluctuates

[SteveRo]

Amazing, just updated from x58 extreme/i7 965 to ud7/3520 - took less than two hours and this with water cooling.
I was even able to use the same w7 install - didn't even have to re-install windows!
All is well so far - impressive -

Well it appears that I'm stuck at 4.5 for now, I've been working on 4.6 for over a week now and have had to reinstall Win 7, 3 times already.

I may end up throwing a smaller single drive in with XP just until I can get her stable.

Win7 x64 is harder to get stable in than XP 32-bit, though, so if you get stable in XP it doesn't mean you'll be stable in Win7...

[sRHunt3r]

It could also be the 2 ssd's in raid-0 with Win 7 combo at high clocks that's giving me fits or that my 920 just doesn't like 4.6. Too many variables I think I'm getting a headache

Thank you !

Can you post your bios template please ?

you need a QPI of 1.50-1.56v for 2000MHz.

[lawtq]

Really

Bios F4 didn't work well for me, got some random freezing at idle which I think related to low VDIMM as 1.640v bios gives 1.616v in windows and DVID looks buggy.
I reverted back to F2 bios, 1.640v vdimm bios gives 1.632v in windows and has been running without a single freeze for 2 weeks before I flashed to F4. I will stick with F2 for now

[Intratech]

Really

Yarp.

dvid is disabled for me since I manually set my VCore at 1.9375V. My VDimm is set at 1.600 in BIOS and ET6 shows 1.584V but I'm completely stable. Using the F4 BIOS without any issues.

Is QPI 1,50-1.56 safe for 24/7 ?

Hi people,
since i am new to Gigabyte boards, allow me please to ask a kinda newbie-ish question.

The mainboard largely avoids explaining much about the secondary BIOS chip, it just says that the secondary BIOS isn't flashable by the user.

Is this actually a full secondary BIOS, or just one that privides generic reflashing fuctionality for the main BIOS?

I am just seeing a problem here if the secondary cannot be updated. If it were a F2 BIOS, and the main BIOS a F4, and you are running a hexcore...your flashing goes wrong sometime and the board falls back to the secondary F2.

I guess you see the problem too?

Enlighten me, buddies.

My UD7 is constantly showing C1 error on the display ... Can u guys tell me what this error means? RMA time for the motherboard? or should I be trying something else like borrowing some rams from a friend and try that?
Need a quick reply ... 10x

After Main BIOS update successfully, system will reboot and during POST, press Alt + F12 key to update Backup BIOS .

c1 is error ram.

[stasio]

c1 is error ram.

C1= Detect memory, Auto-detection of DRAM size, type and ECC, Auto-detection of L2 cache

did you try to clear cmos?

[kagula323]

did you try to clear cmos?

at least 4 times

[SteveRo]

Making progress -

[SteveRo]

did you try to clear cmos?

I assume you tried going down to one stick and diff. sticks of mem?
Closest white slot I think.

Hello !

I have problems to config GSKILL Trident 3x2 2000Mhz at 1600 with timmings 7 7 7 20

I'm sure it is possible.

I test with 1,4v and 1,5v in qpi/vtt and 1,66v in vDimm but nothing helps.

Can anyone help me ?

[Sam_oslo]

New Cinebench 11.5 is just released, download. I had to give a shot on my 24/7 setups, and getting:

@4.22(222x19) 7.20 pts
@4.51(215x21) 7.70 pts

Try setting your IOH core to 1.32V and your QPI/VTT to 1.555V or leave them on AUTO.
