thats better , just drops to 1.308 from 1.333 in the bios , thanks

[dinos22]

use Level1

[Andrea deluxe]

my oc...

use Level1

on actual official bios there are only enabled/disabled/auto

HT OFF
SP1



129gflops

last official bios for UD5 was still showing levels also

F7D was pulled, wonder what was wrong with it, dinos, any ideas?

[bokoy]

Hi, i would like to ask you something.
I heard that with the ud7 if you disable c1e, speedstep, turbo... and all those features the clocks are ever at the same speed, i mean you change the main multi, does it happens also in ud4 and ud5??? Ever at 4.5, 4.6, ...?
Thanks in advance
Regards

Ive also found F2 to be the most stable and requires the least amount of voltage for a decent OC. I can successfully OC to 4.6 @ 1.3v....For every day use I have it down to 4.3 @ 1.2v. When I use F6 or F7B - this OC fails miserably

Im going to stick with F2 for now as I like 4.3 @ 1.2v...Idle temps are between 26c-30c..Load is @ 50c...

My MAIN issue with this board is the USB3.0. Any time I connect a 1TB+ drive it detects it, then drops it, detects and it drops it...While doing this, it sees a drive but suggests I need to format it....Very annoying.

For it to remain connected, I have to first connect it to USB 2.0 and then back over to USB 3.0..

Anyone else have this issue? I too am seriously considering returning this and getting the P8P67 Pro...

can you upload and link the f2 bios pls... ?

F7E is out

F7E is out

Any idea what it changes/fixes?

[kevink82]

To avoid vcore drop change vcore to normal and use dynamic voltage + instead with llc on u get almost no vcore drop.

[Forceman]

This may be old news here, but I just discovered that upping the Vtt and Vccsa on my board by a notch each, helped me get Prime95 stable on clocks that were previously failing (even though they were passing LinX). Running 4.8 with 1.4V (1.38V load) now.

[Andrea deluxe]

Please tell how many volt you encrease..

[Milky1]

Has anyone had a chance to test the SATA 3 speeds yet? just asking as I saw somewhere that some motherboards SATA 3 ports can be a waste of space.

[Forceman]

Please tell how many volt you encrease..

I ended up moving the Vtt to 1.10 volts, and the Vccsa to 0.945

[Lsdmeasap]

I don't see nothing wrong, with a little bump n grind...

Ohh, sorry I mean, I don't see anything funky when you get these boards cold



Best Bclk I could do at -45C, 1085 set in the BIOS.

Updating BIOS now to check for max multi. I'm glad I tried cooling these down and putting aside what many people have observed.

I could barely do 102 Bclk at normal temps. Previous max multi was 51, lets see what colder temps can do!

UD4 is Rocking!

[dinos22]

my chip doesnt do more than 104.5 on air lol

[stasio]

Coolaler already clock at 110.74 bclk and 5.5GHz.

best bios 4 me is f7b.......others bad

[Gaul]

anyone explain ?

Sandybridge maximum safe voltages

Core Voltage - Not recommended too exceed 1.38v, doing so could kill the CPU, we therefor recommend a range of 1.325-1.350v if overclocking.
Memory Voltage - Intel recommend 1.50v plus/minus 5% which means upto 1.58v is the safe recommended limit. In our testing we have found 1.65v has caused no issues.
BCLK Base Clock - This is strictly a NO, anyone using base clock overclocking could/will cause damange to CPU/Mainboard. (Set manually to 100)
PLL Voltage - Do not exceed 1.9v!!

One site/person's opinion?

[Lsdmeasap]

I think about 102 is the limit for this one on air, not sure though as I think I only tried once and it may have been at a high multi?

Well Phase was easy to use and didn't cause any issues, but it also didn't get me any higher CPU multi either. So 51 must be the limit of this CPU, or I need to maybe try again with UD7 and see if that will help. I do think phase would be nice to use for benching, I didn't have much time to play but I think it would help keep high clocks stable easier than air/water.

I do have to say, WOW, the older BIOS is much more stable when it comes to failed overclocks and rebooting at high clocks. I used F3 for a long time and it was like X58/P55 with failed clocks, but as soon as I moved to the newer BIOSes to try with CPU PLL option everything hit the fan when it comes to failed settings and rebooting, ect. That made it super bad for me, I was using a screwdriver to start the board and clear CMOS I need to order a set of switches

Hopefully they can fix these issues, otherwise I may just go back to the older BIOSes on UD4 and UD7 for my reviews. I think that may be ok for me anyway because I can boot x51 multi without CPU PLL option, which makes me surprised that even with the option enabled that is all this CPU can do.

I'm gonna try to find a retail soon, if I can scrounge up the cash.

Wow, I can't beat that!

What is max you've seen on Gigabyte Stasio?

[wekktor]

1. Which bios is the best?

2. Does any bios make it require less volt for same clock?

3. If something goes wrong while flashing, are there any way to get it back again? Gigabyte dualbios?

Thx

So far,yours.
