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

[bigwill68]

Do I have to raise the Core voltage to counter the huge vdrop on this board? I am setting to 1.4v and CPU-z is showing 1.34-1.36v. I am having trouble clocking my CPU higher then 4.0Ghz. The same CPU on my Abit would clock as high as 4.5Ghz.

here's the setting on gigabyte boards with or without LLC

BIOS setting 1.4V w/ Load Line Calibration
Idle: 1.376 CPU-Z, 1.404 multi-meter
Load: 1.344, 1.360
without LLC
Idle: 1.360, 1.378
Load: 1.340, 1.312

1.5V w/ Load Line Calibration
Idle: 1.472, 1.496
Load: 1.440, 1.446
without LLC
Idle: 1.456, 1.472
Load: 1.408, 1.423

1.6V w/ Load Line Calibration
Idle: 1.600, 1.611
Load: 1.568, 1.561
without LLC
Idle: 1.600, 1.617
Load: 1.568, 1.563

All gigabyte boards have Vdroop

you can check Vdroop using a multimeter...

Oc'ing due good memory and stable memory get some(2 x 2GB) 240-Pin
ddr2 sdramddr2 1066 (PC2 8500)

[technut36]

just bought the pi black pc7200, i cannot boot over 800 at 4 4 4 12, i set the voltage manually to 2.1. i tried 2.000 D and also 2.66 D but no luck.

any input would be greatly appreciated

try loosing up the timing alittle and see what happens

[technut36]

the only reason i bought these is because they are rated cas 4 at 900. anyhow it does 900 or even 920 but on B mode. Right now i am trying to search around to find the difference between 2.00 B vs 2.00 D

ohh crap i was probably one of the last people to buy it. I just received em today and they are already deactivated.

on 2.00B they work awsome.

currently i am at
CPU: 465x8.5 = 3.95ghz
Ram: 465x2= 930mhz @ 4-4-4-12 2.1v

i cannot push the ram farther then 469 at cas 4 which i think is still pretty good.

[technut36]

currently i am running vista ultimate 32bit, i have a copy of 64 bit. How does this mobo handle 64bit setup, is it smooth.

[njl]

Not to hijack this thread, but the ppl reading this one seems to know their UD3P.

I'm having serious problems with mine after going to watercooling - if you think you can help - please do so here: http://www.xtremesystems.org/forums/...d.php?t=210326

[Ledge]

Alright! Now I am happy! I enabled LLC and made some other changes in the BIOS and got some great results. I did have to raise the Core voltage to 1.41v to hit this FSB but that is nowhere near what I have had this CPU up to in the past.

@ ledge, your pll voltage is way to high. you should be able to drop that to 1.57 or lower.

@ ledge, your pll voltage is way to high. you should be able to drop that to 1.57 or lower.

I had it set to AUTO. What is the max I should have the PLL and CPU termination voltages set to?

If I set the PLL lower then 1.6900 I get stability issues?

[radaja]

depends on what your comfortable with. i think most try to stay below 1.60.also if you keep things cool (good airflow) you should be ok w/1.69 i think. im probally not the best person to be asking cause i dont like to go to high on any of the voltages.right now im using pll1.57 and im trying to lower it to 1.5(not comfortable with 1.57)and vtt not really sure but i keep mine below 1.4.but still not 100% sure . please feel free to correct me if wrong.

[SPQQKY]

It is not recommended to use LLC.

Yes, please elaborate on why keeping the voltages rock solid is not good for 45nm CPU's???????????

currently i am running vista ultimate 32bit, i have a copy of 64 bit. How does this mobo handle 64bit setup, is it smooth.

I have Vista Home Premium x64 installed and running smooth as silk with 4 x 2GB G.Skill Pi Black @ 900 4-4-4-12 2T.

Sadly, I am not able to boot into Windows without going above the max recommended voltages when going for 4.0Ghz!

I was able to run 24/7 at 4.0Ghz on 1.38v core and 1.1v FSB on my Abit.

With this board I need 1.41v core, 1.5v CPU termination and 1.6900v PLL.

I did do one more max FSB run and was able to hit 550Mhz which is 50Mhz higher then I could hit with the Abit board.

I just wish I had a spar CPU laying around!

[SpeedEuphoria]

Hey I need some help as I'm a noob at OC'ing Intel's. I have an E8400 E0 and UD3P. Basically I have been messing around and 3.6Ghz is easy 9x400 I keep lowering the CPU Vcore, currently I'm at 1.175 in bios and 1.136 reported in ET6/CPUZ. I have been just doing this as it seems that I'm missing something as anything I try it wont boot above 400FSB. I'm on the F5 bios, my mem is OCZ and running on the 2.66D currently at 1066 PL8 5-5-5-15.

I didnt think that I would need to mess w/ the ram timings so far as when I bump it up I go for the same 1066 speed. But maybe I need to change to PL9?

I raised all the voltages, left the reff on auto as I though they would keep a good ratio?

What am I missing?

Am I supposed to only have 4 led's light on the board I turned all the DES stuff and in bios off so I thought that it should stay at full power so 6 led's?

Also I'm kind of disappointed as the DES seems to only lower voltages if your on stock settings. It will still lower the multi when you OC but stops lowering the Vcore, or am I missing something?

Ledge, ditch the F5 BIOS, it did not play nice for me. Try the F7a beta BIOS. I was having trouble with 4GHz and a lot of voltages as well w/ F5. After flashing to F7a, I can run 4GHz with 1.3175v set in BIOS w/ LLC enabled giving me a rock solid 1.29v according to cpu-z, OCCT and ET6. I also only have 1.35 PLL, 1.22v cpu termination and 1.32v MCH. It SHOULD make a big difference for you as well.

That is what I have been using. I downloaded the F7a BIOS right after I installed the board.

I did get some BIOS settings help and was told to adjust the CPU skew (350) and MCH reference (200) and it worked. I am now able to boot at 4.0Ghz with PLL at 1.57 (I have not tried lower yet) and CPU termination at 1.3.

Thanks for the tip on the BIOS though.

it will not allow at 4-4-4-12 it's to tight to at that oc on the cpu loos'en it up to 5-5-5-15 as 1066 memory and.I bet you get 469 and above..I managed to
with some Corsair XMS2 2GB (2 x 1GB) 240-Pin ddr2 sdramddr2 800
http://www.newegg.com/Product/Produc...82E16820145034

sorry about the shot Networking between Machines to take this shot here it is
from my antec 300 case with the ga-p35-ds3r machine with my E6750 alittle
oc'd had to 3.6ghz stable b4 turned it down sense was at 3.8ghz stable with
some Corsair Dominator 2GB (2 x 1GB) 240-Pin ddr2 SDRAM ddrs 1066 but took them out for another board...
best a luck my friend and hope it works out..I plan to get some of that memory also later on there's only a alittle differents between the p35 and p45
bio's setup..i got p45 gigabyte board under my bed ds3r..

[Ledge]

I am really starting to love this board!!! I still have allot to learn about the BIOS settings but, I am getting great results thus far.

570FSB on air with my old C0/M0 E8400. Thanks to all that gave me tips and help.

[noinimod]

Ledge: Awesome results.. are you still trying for higher speeds?

[Ledge]

Ledge: Awesome results.. are you still trying for higher speeds?

Not tonight but until I find the max I will continue to try.

I am sure that 570FSB is not my max as it booted and ran without any stability or heat issues. I have to play with this BIOS for awhile longer before I will be content that I have hit top speed!

Any help ?

[BuGjAE]

@mathewgx I have the same error as your post after Orthos blend 3-4 hrs,It like a random unstable...... Some people advise to adjusting CPU PLL ,CPU VTT ,MCH REF to the stable spot may help you. But it's not easy to find....

[fatguy1992]

I just got my UD3P. Could people with Q6600's please post me their settings. I don't care what GHz as long as its stable. Thanks.

I'v never used a mobo with this many settings before and I just need some refences to look at.
