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

[Nelly]

The endless reboot issue has me stumped. I know when I tried a setting that didn't work it would reboot three times then reset itself to stock and boot. If I had a setting really out of whack it would try to boot but never get to the BIOS; a CMOS clear would fix that. But never an endless loop of reboots. I hope you guys can come up with an answer.

Not looked at your other posts, but have you tried with 1 stick of ram then manually setting the correct voltage for the ram once in bios, then place the other stick or sticks of ram in the motherboard?

Thanks, mine works fine, I was hoping the others with the endless reboot problem can find a solution.

has anyone else noticed the UD3L and UD3LR for sale? anyone know the differences between them and the older UD3 boards?

im building a rig for a friend of mine and was curious if anyone had any experiences with those boards. he wants a quad core plus a lot of ram and wants to get an entire rig running for under 900 bucks, and shaving 30 off of the board price will allow a TRUE instead of a AC7/Xig.
i suppose we could run a q9400 instead of a 9550 for the price savings if the UD3LR is totally out of the question.

What BIOS are you on? I was on F7a when that kept happening to me. I flashed back to the F5 BIOS it came with and it hasn't happened since. I might actually give F4 a try since a lot of people are saying it's better for quads.

Are you saying it does the endless reboot loop at 100% stock settings too?
If so check your components.

Otherwise: Quote from Clunk.org.uk...
Static tRead Value Available options 1~15. This is the crucial tRD on earlier boards (shown in memset & elswhere as Performance Level) If your rig is reposting continually chances are its because of this value being too tight. It's nice to have it channel based as it's sometimes practical to run at 8 on channel A and 9 on Channel B for example.

[stn0091]

Isn't PL 9 usually a sufficiently loose value for most overclocks? That's where I had PL at when those reboots happened; dropping it even lower to 10 doesn't seem like it would do much good.

i had the endless reboot where it would never even get into the bios ,once. it happend when i tried to use my new mushkin memory. the problem was one stick was bad,took out one stick still endless boot,took out second stick put in first stick back in then it booted right up.thats the only time ive gotten the endless reboot.but when you have performance level too tight ,it will boot three times then take you back to bios with red OC failure screen so you can make the needed adjustments

[ghost_recon88]

Whats the general consensus regarding a BIOS for a quad? F4? or F7a?

[stn0091]

F7a gave me endless reboots (more than just the usual three with F5 and F4) when I put in settings it didn't like. F5 is decent, but I like F4 more since I don't have to raise voltages as high.

Just installed vista 64

For some reason my 4850 ATI Graphics card is showing a 1.0 Score in Vista experience for both graphics results. Strange thing is my 3D Vmark is about 7k.

I been searching all day for an answer and can't seem to find one. I am using all the recent drivers etc.

Anyone have any ideas why this might be happening? Everything else gets a 5.9...

Thanks!

[SpeedEuphoria]

Did you retest it since installed?

I have been struggling with this board and have found that by far the most important part in the bios is the MCH reference!!!.

@1.184Vcore in windows I tried everything to get prime going, everything I tried failed in 1min. So setting the MCH correctly has gotten me a couple hours on the same settings, PLL/CPU term are at stock

[36Chambers]

Fixed it...

Seems as though you need to follow these steps to get corrupt scores out of Vista:

1. Click Start, type the following path in the "Start Search" box,
and then press ENTER:

%SYSTEMROOT%\Performance\WinSat\DataStore

2. Delete all the .xml files in the folder.

3. Click Start, type performance information and tools in the Start Search box,
and then click Performance Information and Tools in the Programs list.

4. If the following information appears, click Refresh Now to update the
Windows Experience Index:

Your Windows Experience Index needs to be refreshed.

If you are prompted for an administrator password or confirmation,
type the password or click Continue.

Windows Experience Index assesses the components in the computer.

5. Note the value that appears next to Your computer has a
Windows Experience Index base score of.

6. Click Update my score.

4 phase power :/

can it handle an OC'd yorkfield without blowing up? im guessing no

[JINU]

anyone got the EP45T-UD3P?

anyone got the EP45T-UD3P?

Please read thread title prior to post

[Ledge]

anyone got the EP45T-UD3P?

Pretty much everyone in this thread has one.

[radaja]

he's asking about ep45 T-UD3P. the ddr3 version.

yes the ddr3 version. wondering if anyone has it and was able to get to do any overclocking.

Anyone else have annoying high pitch noise from the power on this board when DES/C2E is enabled?

I have read about issues with other people videocards ect.. before where they would make a high pitched noise. Well my board makes an annoying noise when I have the DES/C2E enabled. You know the 6 lights on the board, well this noise corresponds with the 2nd green led or 2nd phase power supply. So currently that is the light/phase that is on at idle on my computer and this noise is driving me crazy. If I open a program it will throttle up a little and then the sound goes away for a second or I get like a fast beeping sound when its throttling.

Any help? Should I RMA it??

I'm not sure what you mean - is it a high pitched whine/whistling from the mosfets under load?

If so I also have it during IntelBurnTest and other testing programs that max out the CPU. Found out yesterday that it also occurs when playing Crysis. From what I've read here it's normal.
Although I haven't tried disabling C2E to see if the noise will disappear.

If that's not what you're talking about, just ignore my post :-)

I just did some quick tests on max fsb and GHz with my Q6600.





It was easier to hit 500FSB on my UD3P then it was to hit 470FSB on my P5E . I would have got 4.0GHz easy (500x8) if it was so hot today - dam summer

I need a bit of help from you guys.

I've got my system 24/7 stable at 460x9, but naturally I want more...

My goal is 500x9 so on my way there I'm trying out 480x9.

I can pass IntelBurnTest and have currently been running Prime95 for 8hrs.

The problem is that if I download e.g. a zip-file of 60MB, it will be corrupted (Winrar reports this).

Everything works fine at 460x9.

I've tried raising vcore, MCH, GTLs - and just about everything else - and I *still* get corrupted files.

My settings at 460x9 which is stable:

mem freq: 920 (2.00B) - haven't played with this yet
mem timings: 5-5-5-15
LLC: enabled
Vcore: 1.3625V
VTT: 1.36V
PLL: 1.5V
Cpu Ref: 0.861V

MCH: 1.36V
MCH Ref: 0.861V
MCH/DRAM: 0.9V
ICH I/O: 1.5V
ICH: 1.2V

DRAM: 2.1V
DRAM Term.: 1.05V
CH A Ref: 0.9V
CH B Ref: 0.9V
--------------


And my "stable" settings at 480x9 that will corrupt files:

mem freq: 960 (2.00B) - haven't played with this yet
mem timings: 5-5-5-15
LLC: enabled
Vcore: 1.4V
VTT: 1.38V
PLL: 1.5V
Cpu Ref: 0.874V

MCH: 1.38V
MCH Ref: 0.874V
MCH/DRAM: 0.9V
ICH I/O: 1.57V
ICH: 1.2V

DRAM: 2.1V
DRAM Term.: 1.05V
CH A Ref: 0.9V
CH B Ref: 0.9V
--------------

Can you help identify which settings I should change to get this puppy stable - and hopefully closer to my 500x9 goal?

Thanks!

Any info on new revisions being released?
