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

[clo007]

He said UD3R. The latest bios for the UD3R is the f6 bios

[APC]

Tanks

I´ll update my bios to F6.

[Loony]

I just got the UD3P today and OMG!

This is a nice board! You can tell right away how sturdy this thing is. It's very stylish too.

I'm just waiting on my E8600 to get here and then the fun will commence!

[Bail_w]

i have a UD3P with a Q6600, i am having some trouble to coming up values for CPU and MCH references.

The ud3p does a great job of cpu and mch references by itself; but, there is a
certain way you have to do it. Try this;
In bios set your CPU termination manually to 1.2
Then set your cpu ref to .76
Then set your mch ref to .76; not auto...
Then....Increase your CpuTerm to just a 'little' below your VCORE, maybe a notch or two. Your cpu and mch ref. will change when your change your VTT (cpu term)
If you are not completely stable after that; raise your mch ref one notch.
See if that helps. It has always worked for me.
BTW thanks for all the posts/info from Jor, viper, and all the other gurus in this thread. All you guys really helped me (saved me a ton of time). This thread is great!

Thanks but it seems like its not helping much. Right now, i am trying to achieve 3.91ghz stable on water. These are the settings i am using:

CPUL PLL: 1.71
CPU Term : 1.24
CPU ref: 0.76
CPU Vcore : 1.5
Mch Core: 1.4
Mch/DRAM ref: 0.9
MCH ref: 0.800
Ich I/O: 1.5


I was able to achieve 3.87ghz OCCT stable, but when i try to go for 3.9ghz, the system would automatically restart at about 48 minutes remaining. Anyone have some suggestion what might causes the system automatically restart? i tried to up the vcore to 1.55v, but still automatically restart.

Here you go all you UD3P guys, check this out

[Bail_w]

Yes, OCCT stable at 3.9ghz

[bobreece]

what does the ram setting standard turbo and extreme actually do? is it not better to just tweak your own timings?

[PakaPaka]

Bail_w, really good result.

cooling with?

water
update your signature with your new stable speed (?)

Yep, cooling on water.

Well the thing is i still can't figure what causes the system to automatically restart while priming with Linpack.

[PakaPaka]

Vcore?
Linpack love Vcore very much from what i see.
i need for my E8400 1.328V for run OCCT 5 hours stable on 4.05GHZ and for Linpack i need 1.336V :-\

how much NB voltage you gave that CPU for OCCT?

[Ghostleader]

Yep, cooling on water.

Well the thing is i still can't figure what causes the system to automatically restart while priming with Linpack.

Probably to low vcore.

Any links available for the GA-EP45-UD3P F4-4 BIOS?

[Supershanks]

Performance Enhance Same as X48 & X38.
Yep it probably is On P45 tend to leave it on default Turbo, nut 905% yep manually set tRD

[Leeghoofd]

Thx Stasio can't wait to test the new bios but have to finish the review first to keep the results in line... good job man !

EP45-UD3P.F4Pi

Awesome Stasio, much appreciated.

Probably to low vcore.

I tired with bumping from 1.506v to 1.55v in bios, still the system restarts while priming linpack.

Linpack love Vcore very much from what i see.

i believe you meant MCH voltage right? which is 1.4v

is the F6 bios more stable than F5 on ud3r?

[TheGanG]

Which one?

Gonna buy a GA EP45 UD3P as a bench kit, will it be a good choice?
Want to use a E8600 and a Q9650 on it (dice pot)

Thanks...

Oh one more question, are all UD3Ps rev. A3? Rev A2 P45 chipset sucks

UD3P are either rev 1.0 or rev 1.1, where do you get A3 and A2?

EP45 UD3P = A3
EP45 Extreme an older models = A2
