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

[gurusan]

It's absolutely easier than the EP45C was. I really hope you have better luck. I saw someone else running one at 550fsb with DDR3 but I really have no clue how he was able to do that.

It could be that the board just didn't play well with my OCZ Plats... dunno. I am still having some problems running at 1800MHz CL8, but can run 1600 CL7 fine...I will play with the board a bit more later on

I just purchased the EP45-UD3P after reading this thread.
I am coming from a Biostar Tpower P45 board combined with my low vid Q9550.
The Biostar just couldn't clock the Q9550 with a 1.17 vid to its potential (4th core is stuck).
Here is a introduction run to test possible voltages on the Q9550.
I installed a pair of my D9GKX Buffalo Firestix 512mb sticks, before moving onto the expensive D9GKX Cellshock's
I combined many of your templates with my own insight to lead up to these results .

^^ very decent Chad. what cooling are you using? nice cpu, have you had that long or purchase recently?

Great for you, nice work! Hopefully I'll have good luck with the Ripjaws on mine.

Hey everyone,

is there a known issue with these boards and sound cards? I've use 3 different sound cards plus the onboard audio on 2 different P45-UD3R's and 1 UD3P and I'm getting crackling in my audio on all of them. It is driving me crazy.

(right now I'm listening to music and it's crackling)

CPU usage is not high, and I know it's not the amp/speakers because I tested it with an iPod connected directly to them.

HELP!

very nice chad

Hey guys I've been running this board for a while and was wondering what the main settings in the bios are that I want to pay attention to when overclocking.

Currently I'm sitting at 3.6Ghz with just one bump in vcore. I know not to go over 1.4 on one of the settings I think it was the fsb termination or some such.

I haven't read this whole thread but I figured it's easier to post and get a quick rundown from somebody who really knows what they're talking about. Thanks!

[Hoss331]

Gurusan, what PL was used for this run and have you tried it on any other bios?

Well I just got my EP45T-UD3P up and so far so good Running F8C bios.

[winston856]

So I'm posting this at 4.1GHz, I got here by just bumping the vcore and nothing else.

I have a weird problem now, I just booted into windows and Aero basic is on. Basically windows says I don't have a videocard. I can't see my nvidia control panel when I right click on the desktop.

wtf?!

Edit: Downclocked to 3.6GHz and now everything's back to normal. So obviously I'm not giving it enough volts for 4.1Ghz, guess I'll add more vcore and go from there. Which other settings should I change to help stabilize the system?

Edit2: The system seems to just shut down when I push 4.1Ghz, I know I'm missing something but what? I was at 4.1Ghz with 1.32vcore and I bumped the fsb term from 1.2 up to 1.26 and after I rebooted there was some weird squeaking/squawking coming from my case. It kind of freaked me out so now I'm back at 3.6Ghz. What is going on and what volts do I need to change to make this stable.

andressergio i finally got a low vid q9650 and board died
i wonder who convinced me to cancel my boycott
the only good thing is that i saw cpu priming @ 4.6 for 10 min before the :exlode:
took me an hour to post this as i had to calm down lol

the good thing is cpu still alive

[gurusan]

Gurusan, what PL was used for this run and have you tried it on any other bios?

That was PL8 and nope, as far as I'm aware F8C is the latest and best bios?

These are the kind of posts that put a little concern into me using this board as part of my workstation. What revision was that board zsamz? Are there any hints people could provide to help aviod the board going kaputt on me? I'll have a w/c nb, and will probably put my copper enzotech mosfet sinks on it, so heat shouldn't be a problem.

I had a missed delivery and am about to go check what it is... May be posting on here again real soon

Are you serious? You really manage to kill every Gigabyte board around you....

its a metaphysical law...he hates them so the board fail and die

I'm afraid you're right...

[andressergio]

I'm afraid you're right...

for sure

[Hoss331]

Will that strap drop down to PL 7? Im not sure if F8c is the best yet, the latest few bios for the ddr2 boards have reduced bandwidth and higher latency is why I asked.

[gurusan]

No it's not stable at 7. maybe i'll try a different bios, I dunno....the F8C isn't that new though although it's the newest. I was hoping there'd be an update soon :/

[zsamz_]

i guess it was old lol time had come
but was only a few months old

i hate gigabut ceo will he die too ?

[humeyboy]

@ winston856, 1.45VCore and 1.45VTT is safe with good air cooling, above that only for testing/benching to find stable OC.

Too much VTT and PLL is the quickest way to kill your CPU not VCore.

The rumours of degrading were never proven, obv its ain't going to take same voltage as older 65nm CPU's and like all CPU's will not last as long if you Overvolt+Overclock but it will last you as long as you need it.

Got bored so I put my giga rig back together. Testing my e8400 eo for max stability, it is no golden chip for sure. Added a Scythe 133cfm to the H50 with some AC on the little rad, temps are very good. Just starting this run but wont do real long blend runs to save some time. This is the DQ6 not the UD3P board but that thread has been dead for so long I am posting in this thread. Will keep pushing this hard for max stable oc as long as temps hold up.

no one?

[bluestang]

no one?

What sound card and what OS? Also,I thought I remember someone posting in this thread about a certain slot it needs to be in.

[OC Nub]

Did a very short blend run and 20 passes of LinX. Will keep pushing it.
