** Official ** Gigabyte UD3 P45 Series -- EP45-UD3 / EP45-UD3R / EP45-UD3P

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

Ahh makes sense, was never sure the reason.

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?

---

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.

---

Anything unlisted is auto.

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...

Cheers

Whats your Q9650 vid mate ? i got all templates from 4000 to 4900 on the Q9650 just to try, but tell me your vid plz

:( How does one determine the processor Vid?

Coretemp or Realtemp will tell you the vid. In Realtemp under settings check the box "VID Information" in version 3.30beta

I'm getting problems with my PC just spontaneously rebooting when running linpack with 1.45vcore or more. Tested at 400x9, which is linpack stable at 1.344v, if i increase voltage to more than 1.44v PC will reboot after a couple of minutes of linpack :( I previously thought it was my PSU not providing a clean enough current, but after buying one for £95 (corsair TX750W), it still does it. Does this sound like my VRM's are overheating? Any help or advice will be appreciated.

EDIT: oh and it's not CPU temps, max i got during linpack was 78c which isn't enough to make my pc reboot.

May just mean you are not stable. Try some blend, if it passes prime blend it is possible that the high temps are causing it to crap out and reboot.

Just got my hands on a q9650, IIRC, same batch as you ocnub... L847C037 with a vid of 1.15.

This replaces my old L826A965 with a vid of 1.25.

I'm excited. I'll post as soon as I get it.

hopefully it will do a bit better than the old one.

Hi thanks,

I'm pretty sure the memory sub-system is stable at 400x9, i gave the NB a bump anyway just in case. I only found that it kept resetting when i was trying 3.8ghz on linpack with 1.45vcore (passed prime95 small ftt's for 8hours). That's when i tried 3.6ghz with the same voltage, and it resets on linpack when vcore is above 1.45ish :/ It normally does it on the 3rd test (other tests passed as well).

Anyway, will be getting a 45nm quad soon so most probably won't have to use above 1.4v, and temps should be better.

ps. Is it important to keep VTT close to vcore regardless of FSB? as i was using stock when i was trying 400x9 with 1.45vcore.

Awesome vid, Congrats. :up: Hope you have great success with it.


Oztopher, I am not familiar with the q6600 but I try and keep the vtt below 1.360v for daily use on my 45nm quads. I know with the q9650's anything above 65-70c will cause it to become unstable, thats why I thought it may be the issue.

Ahh i see, thanks mate ;)

Guess i'll stay at 450x8 for now then, until i get my 45nm'er.

where the heck did you find that batch?

I've had my eye open for it since seeing what ocnub has done with his.

As soon as I located one (another forums f/s section), I bought it. It happened to have been a seller who I've dealt with before, so I was quick to pull out the cash.

I found some stability at 4.2Ghz

http://i32.tinypic.com/24qjqx2.jpg

Your mch ref looks to be a little high. Try it at .80 with default cpu termination of 1.20 then raise the termination back up to where you are now. I always default the cpu termination to 1.20v then set the refs. Everything else looks good, nice job.

I need help...I am not sure what I am doing wrong but the chip is a little warm and the FSB just won't budge. Can anyone improve my settings?

Machinus, I really think you need more MCH voltage...also what is your PL set to?

What do you mean PL? Why do you think MCH is too low?

Performance level...its known in the BIOS as Static tRead value under in advanced timing control...also what RAM do you have...you should put your system specs in your signature

Your MCH might be too low based on what Ive seen from other setups in this thread...you might want to take the time to do so, as i did, at least from page 50

Static tRead is set to 8. RAM in sig.
