Hi Guys...

A bit late to the party wiith this one but hey! My old motherboard died

Just a quick question as i'm a bit rusty with the P45 chipset...

Just bought a PCI-e 2.0 8x RAID card and installed it in the second slot (it works fine) but my GPU in slot 1 now only has 8x lanes available...

I was led to believe that it would only drop to 8x 8x mode if 2 graphics cards were installed but here I am with 8x 8x mode with only one...

This led me to think that the P45 chipset only has 16 lanes total available and the board will drop to 8x 8x mode if you put anything in the second PCI-e 16x slot.

As a result of this i am losing about 4000 3dmarks in 3D01 and I would like them back

Am I right?

[Homeless2]

Anyone have any idea why I can't get 485 fsb stable? Prime usually errors out or the system freezes within 20 minutes. Have tried using F9 and F10e bios'es with no avail. Currently testing on F9

Here is my current 24/7 settings, still more vcore than I had expected to use but temps are fine since I'm on water.

Not too bad of memory bandwidth for 8GB on a Gigabyte board with DDR2-942

PLEASE! Can anyone help me?

Thanks!

Hi guys.

I'm haveing serious problems to oc my EP45 UD3P. I've tried every that i tought and was possible for me and nothing tought 450FSB!

Once i got 500FSB but unstable, just for few mins!

The maximum stable that i got was 450FSB/1.41v/5:8 1080Mhz 5-5-5-15.

Once i got 3.8Ghz(475*8 ) 1.43v with an ASUS P5Q Deluxe. So, my problem wasn't CPU!!!

To get 4.0Ghz(500*8 ) i need 1.55vCORE and everything @ AUTO, but just for few mins and crash!!!!

Can anyone help me?

Thanks


4Ghz(500*8 )

Any risk in flashing a 1.6 version of the EP45-ED3P with a 1.1 bios?

[LifeDrainer]

I maganed to run 3DM01 with this setup, 40MHz increased resulted in crash. Pretty high temps + not so much time resulted in not so many tweaks...

I'd like to pass 80k .

I don't know, but why would you want to do that? I ask, because mine's a rev. 1.6... and if there were any advantage, i'd be interested.

[BuGjAE]

@kelm as I see your setting ,think you might adjust CPU reference and MCH reference ,problably increase up 2 notch or more to show in ET6
=cpu ref 0.8
=mch ref 0.8
I don't know why but someone tell me when using quadcore Ocing with around 500 FSB this should be up a little,and make sure your Vcore can hold you cpu clock.

Could someone post a working link to the UD3P F10e and F10b bios please as the Tweaktown links are down...

Thanks in advance

Edit:

Never mind...found them

Working link here

[18 is # 1]

This is Orthos stable



Having a hard time getting any more FSB to pass.

Does anyone know anything about placing a NB water block on here? Does the heat pipe just slide out of the PWM heat sink? I'm new to this board and I have yet to make my way through the entire thread.

P.S. It needs more volts than my DFI P35 did.

Correct.

The heat pipe is lightly glued into the heat sink, but give it a little twist and it will slide right out.

finally got the w/c set up and running. got a quick and easy bump to 4400mhz, need suggestions to get 4500+

this is my setup:

I have tried to get more the past few days, using several different settings and what little I know from reading forums and observing what works and doesn't work in my system. I know the cpu seems to requie less volts than many of you. I spent several weeks testing different bios settings with th hsf, and hit the wall at 4.3g. Frankly, all I know to do is guess and keep trying. Windows 7 doesnt seem to like bios crashes, and I have had to do a complete reinstall from my server several times. If anyone has advise or could point me to a thread that tell the relationship between settings and how to intelligebtly overclock it would be greatly appreciated!

Thanks

[nugzo]

I need some input from the ud3p v1.6 users. I have another ud3p comin in tomorrow from the egg, i assume it'll be a 1.6. Anybody know what the difference is between the different revision boards? Something would have to be way different for the 1.6 to use a different bios right?

[Triton]

I ordered the OCZ Blade PC2-9200 Low Voltage (1.8v) 2x2GB kit, overclocks feel more solid now.

4312MHz (1.344v CPUz, 1.381v BIOS), Mem 1150MHz 5-5-5-18 (1.82v BIOS), FSB=1.32v, NB=1.34v was np for the 3DM06 run I just did. Must say that the single most important setting IMO is the MCH Reference, I've had "so-so" success with it at auto, but with new kit I again tested 67% of VTT...the higher the OC, the sooner I got errors with MCH Ref @ auto or 63%. For the 4.3GHz run I set MCH Ref 69%, CPU Ref 67%. No more BSODs with high MCH Ref value either, only errors in P95

[Triton]

I have a cooling tip for UD3P Northbridge (after you've removed the blue shielding cover)

A Scythe Mini-Kaze 60mm (60x60x20mm), 20db, 2500rpm, 48grams, 21m3h, comes with 2pin->3pin adapter, 4x 25-30mm long screws that perfectly fit the UD3P NB heatsink fins. I had NO problems fitting the Mini-Kaze 60mm over my NB(used 2 screws, fan "diagonal"), I've got a TRUE Black with 120mm blowing upwards, the fit is perfect.

[andressergio]

bro sergio.,u can try flashed using gigabyte FLASHSPI utilities from website that come with the bios version.,flashed from F10e to F9 just now working fine..

Worked fine mate but F10e just keep comming back so i let it and i made my best 4905 Mhz validation in it so its not bad lol

aahhh and i saw you where told use 50ps on skews, its not mandatory mate if you wanna boot at high OC you will need 1000/1000/0/0 and high MCH, for lower OC you can use 800/800/0/50 or 900/900/0/50, just keep trying.

Best of luck to ya

Cheers mate

I just finished installing the ud3p rev 1.6. So far the OC settings and limits are the same as my rev 1.0. I was hoping to get that extra 100mhz but i just cant do it. My poor quad wont pass stability tests over 4400mhz. The only thing different that i've found is the 1.6 wont boot with 8gb of pi 9600 at the default 1.8 volts. 4gb boots fine. I've gotta up the voltage then install the other 4gb and all is good. I'll let you all know if i find anything else different.

Oh and if anybody needs the F10e (1.0,1.1 rev.) or the FDa (1.6 rev) bios with SLIC tables added let me know and i'll send them or post a link. I've used both for Windows 7 Ultimate RTM activation and they work perfect.

[TalBar]

Nugzo I had UD3P rev1.1 and trade it to rev 1.6. Both are boards looks exactly the same, but rev1.6 has one new feature in new beta BIOS "Quick Boot" named. With Quick Boot enabled the boot so quickly that i'm not can reed the POST messages. Both are boards i've got the same 8x500mHz with Q9650 LinPack and Prime-95 stable, but i prefer 1.6, cuz i've got it with less VCore, but it needed some more GTL_REF's. With 1.1 settings i can't to boot with 1.6. One more thing- they changed something in hardware too, because when my Win7 installed on rev 1.1 started. it's find several new hardware connected to South Bridge and installed it immediatly. Not any other changed find, but looks rev1.6 some more stable.
BTW, i love this board. All the time i had DFI boards and Gigabyte was really crap in OC, performance, settings and layout, but after i've got the quad core, my great board DFI P45 -TRS Plus was not enough. UD3R(P) it's first great Gigabyte boards that i not shame to have. Well done!

[nugzo]

For some reason everest 5 doesn't show how much power I'm using since installing the 1.6. board. Can somebody with 1.6 confirm or deny this? Thanks!

Hello,

I can't get my 9650 over 3.3 ghz even with 1.38v...I am trying to get as high as I can go sub 1.4v but I seem to be doing it wrong. I moderately increased all of the voltage settings and I am taking it easy on the RAM but it still won't load windows...what to the other 3 CPU settings do, and do I need to worry about mch/ich?
