I dont know if this has been posted before, but here are some real voltages on a UD3R 1.1 (F6 bios if it matters). Tested with a DMM and when I get time Ill test my UD3P 1.0.

          BIOS    Idle   Load
vcore	  1.400  1.408  1.416
pll	  1.450  1.475  1.533
	  1.500  1.577  1.634
	  1.570  1.597  1.655
nb	  1.300  1.326  1.341
vtt	  1.300  1.328  1.347
vdimm     2.200  2.236  2.244

Hi, If its not too much to ask; can you try to test the voltages with the F9 and F11 BIOS? My DMM is a cheap one and doesn't have <2 volt setting so I don't trust it that much but the readings are pretty close to what is reported in the BIOS. Thanks.

[strange|ife]

is it normal for vdimm readings to be high in the bios? I set vdimm @ 1.9v, but bios reports 1.94~ No biggie really

im using rev 1.6 with FDa bios, so its probably just an error in the beta bios.

from reading this they used a dmm and voltages were pretty much right on target with a different bios. Im going to check it in the morning

Did you have LLC on when you did the readings?

[poldo]

it looks like it because it overvolted the VCC values but i don't know why the rest of the voltages are incremented. As far as I know (which really isn't that far), loadline calibration is for the VCC only and not on the other voltages. These increments may be because of an early BIOS which is why I asked to try out the latest ones (F9 and the recent, F11).

[Hoss331]

LLC was enabled and Ill try to test F9 tonight. My board is still mounted in the case so I used the points from here, http://www.clunk.org.uk/forums/revie...html#post42137.

[poldo]

yeah, those were the same read points i use but the problem is with my DMM, the lowest setting for voltage reading is 20v but the manual says it's capable of reading small values automatically. still, i don't trust it completely. oh and thanks for taking the time to test it with different BIOS version.

crashes on OCCT quite fast. And often get reboot loops, but right now its running prime for about 30 mins.

what should i tweak in these settings? Should i crank vtt up or less? my understanding was Cpu VTT should be about 0.04v of actual vcore for stability.

i played with cpu ref and mch ref, but anything besides normal= NO boot at all.

I'm quite alarmed at having to pump 1.42v into MCH just to get into windows=[ So i might back it down to 450x8 for 24/7 use. Passed over 8 hours prime small FFT with that, on much lower voltages across the board.

well anyway time to go to the pub! hopefully when i get back somebody will have chimed in.

[strange|ife]

well i didnt get to the pub lawl.

anyway i fell back to 451 fsb for now because i need to get some gaming in.

now S3 sleep dont work

just turns on and off when i come out of sleep.

the PSU is fine, its something with this board. Im starting to think maybe rev 1.6 sucks compared to the earlier ones.

I just ordered this motherboard, you are scaring me man. I really, hope this one I am getting is not a piece of $hit like the one I just got from Asus man. I can't get past 460FSB stable on this thing when the one I cross shipped back to them did 480 all day with out an issue...

[OC Nub]

StrangeLife: use s1.
I am not familiar with the q6600, but for the 45nm quads these boards are the best.

Voltages did not change with the F9 bios.

edit: I guess my original ground was a poor choice, now getting closer readings.

the bios to actual voltages are pretty close minus pll assuming those updated ones are correct.

[strange|ife]

StrangeLife: use s1.

I will try S1, just set it.

even at 400fsb im getting lock ups now at the desktop with correct settings.

but not at stock/optimized defaults.

last night i was playing around with 550FSB but used all AUTO!

i didnt stress test at these settings, just booted into windows to run super pi.

also ran 8+ hours last night after that with the settings close to what i posted above @ 451FSB, passed fine. Now things have gone down hill, sleep doesnt work..and getting freeze issues.

hope my cpu isnt toast.

dont worry haha

im probably just dont know what I'm doing. I would say try this mobo.

Im going to try another cpu maybe see if its my chip..which i doubt. These Q6600's are tuff customers, would be weird to burn one out, especially with the mild oc's ive ran on it. Although its over 2 years old, so who knows.

thinking i might just return the board tuesday. And put together a Lynnfield set up in a month or two. Once prices settle.

[vailr]

Anyone use the hard drive maintenance program "SpinRite" with the Gigabyte EP45-UD3R motherboard?
A poster on another forum says that the F9 bios on this board is detected as being defective:

excellent voltage readings . just one question; do you have the voltage settings at auto? i still don't understand why the PLL voltage slightly increases during load. try to hard set or type in the nominal values instead of leaving the other voltages on auto.

i'll try to get a reading on mine later then compare it here. i have all the voltages hard set and the only ones on auto are DIMM reference and GTL reference. BIOS version is F11, btw. (F11 seems to handle GTL ref very well at auto, i spent days tweaking GTL reference settings with F9).

edit: were you using a fan header (ground) as your ground on the readings?

[Cutbait]

Recently had my UD3P rev 1.0 die on me after 8 months of use.

Installed a rev 1.6 board a week ago, using bios FDa with a q9650, 2x2gb Gskills

Not sure i can have much input on comparing the 2 revisions as I believe my rev 1.0 was a bit borked from the start. Went from using 4x1gb d9's on the rev 1.0 to 2x2gb on rev 1.6 also

But a few things I did notice

Voltage readings per everest and HWMonitor show the +12v reading @ 12.54 idle on th rev. 1.6 versus 12.14 with a drop to 11.97 load on the rev. 1.0. The DDR voltages seem to hold more constant under load on the rev 1.6 also

Friggin heatsink on the nothbridge was installed backwards (upsidedown) Couldn't twist the sucker off, lines up correctly either way it seems so I cleaned her up, applied TIM. system temps max out at 41C load versus 47C load on the rev. 1.0

As TalBar mentioned in an earlier post, GTLREF % might need to be set a bit higher on the UD3P rev. 1.6. Running a CPU_REF OF .66% and MCH about .65% seems to be stable for me FWIW.


Able to OC my Q9650 at same voltages as rev 1.0.

System 20x linpack, 12 hours large fft prime, memtest stable. And 4 hours of Crysis & Warhead stable

Hopefully those that are more informed than me will be adding more rev 1.6 info. And the bios mutures a bit. With the Beta bios I am running I am just going to be trying to lower some of my voltage. Then I will push it a bit with a final bios.

I have only playing with this board for 6 days but feel gigabyte sent me a strong stable board this time.

Some of my settings for what it's worth

Starting with rev1.1 they flipped the NB HS upside down. IDK why but they are all this way.

[Leeghoofd]

For better CPU heatsink compatability...

[MrToad]

I have a "little" problem with an EP45-UD3P rev 1.0

Flashed it with f10e BIOS... upon reboot it would power on, stay on for abour 2 secs, then reboot again... over and over again.

Powered off, cleared CMOS, now it won't power on. At all.

Anyone has experienced something similar? Any way out (apart from the obvious RMA that is)...

It's going to be fun to undo three loops to take the damned thing out otherwise LOL

Edit: NVM, I managed to do a Lazarus with the board. Good old DFI NF2 times teaches patience :P

None of my voltages are set on Auto, even the references are hard set. The review on Canucks was also showing a raise in pll voltage when under load, but not quite as high as mine though. I was grounding directly to case for those readings.

Im not sure what I could adjust for stabilty or bring up for additional performance, ive overclocked in the past but not since my AMD Athlon XP3000 and i've had a few rigs since then but im not fimilar with alot of these terms and had done lots of readings and found this "Blend" to work well thus far. Please let me know if anything stands out as a sore thumb.

Also I have a very nice high air-flow 10,000 RPM fan screwed into the Northbridge heatsink it stays very cool, (Pulled the blue gigabyte label\metal cover off).

My CPU temps are at idle roughly 32c, load 50.

Thanks!

Anyone?

No damage mate---did you flashed on Qflash ? or Flashspi ? i asume so...

If not take both sticks of ram and put just one on the other slot not the ones you've been using that will make it come again if its all correct, if you have OTHER memory the better...
