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

[Jor3lBR]

Andre, Thanks appreciate it! I've noticed with these boards that less volts is actually better sometimes, expecially with vDimm. My HyperX DDR2 9200's have 2.30-2.35v on the sticker, but will not boot no matter what settings are change in bios until I lowered the volts. My DDR3 OCZ's have 1.90v on sticker and don't like much more unless I'm trying to get 2000 C8 stable, and that isn't working out yet either, but 1600 as set in my sig at 1.90v is rock solid. I know Leeghoofd mentioned once before (maybe in one of his mobo/cpu reviews) to go straight for low volt i5/i7 dual channel memory for these DDR3 P45 boards.

Hey Blue,

So you say the best would be ram's like the G.Skills Ripjaws Series 4GB Kit DDR3 DDR3 2000? 1.65vdimm stock can the BIOS go that low?

I have the opportunity to test the EP45 T with my Quad and was browsing thru which mems to get for this combo and high fsb 550 up.

On my lowend EP45T-UD3LR the BIOS vdimm has a range of 1.10 to 2.76 volts. I was going of off this review by leeghoofd first and foremost. After the pics he explains the difficulties he had with memory on this board. I have also seen others who do much better with the dual channel low volt memory made for the i5/i7. Unfortunately, I wasn't able to find any 1.65v CL8 1600 MHz+ sticks at a reasonable price from TigerDirect when I ordered and built my work system.

Hi all, I got a quick question about the safe voltage for the P45 chip. The absolute max specified by intel is 1.21v, but people are using 1.3~1.4v when OC Quads. How safe it is using voltage in that range? It seems people are judging how safe it is by how well the motherboard is able to dissipate the heat generated. How about the voltage damage like when people are talking about the max safe CPU voltage?

I'm assuming your talking about CPU voltatge? If so I believe with an EO chip you can safely run 1.45V 24/7...some people have even run higher 24/7 and have seen no degradation.

nope, I am talking about the MCH voltage, I am a little concerned going over 1.21v as specified by intel. Sorry for the confusion.

[4x64]

I am currently running MCH Core at 1.30 and ICH Core at 1.20

No issues at all!

HI. I've just installed my Q9550 vid 1.2625 . Can u post some 4GHZ templates I could use for a start? Until now I've only used dual core procesor on my EP45-UD3P. The rest of the build is EP45-UD3P, GSKILL F2-9600 2x2GB DDR2 1200, GEF 9500GT 1GB, Cooler Master Real Power 700W.
Thank's in advance.

If I set my FSB Term any higher then 1.42 it errors out, or it is the NB voltage if I go over 1.52 one of the two. All I know is that it is stable as a rock here. These are the settings I was using for 490 x 8.5 as well I will add.


@Rubber

What cooling method are you using air? If so what cooler? Try my settings listed above maybe, if your cooling can handle it.

thanks for that i found out why i could not go over 3.5 it was the temanation volts for the cpu
here is the settings i have now
can you plesee tell me if everything is ok for 24/7 use thanks guys for the help

cpu host frequency mhz 463
c.i.a.2 DISABLED
perfomance enhance STANDARD
extreme memory profile AUTO
mch frequency latch 333
ststem memory multypliyer 2.40B (1111MHZ)
d-ram timinhgs MANUAL
cas 5
trcd 5
trd 5
tras 15
laodline calibration ENABLED

cpu vcore 1.225volts
cpu temanation 1.280 volts
cpu pll 1.500 volts
cpu referance 0.810 volts

mch core 1.260 volts
mch referance 0.810 volts
mch d-ram 0.890 volts
ich I/0 1.500 volts
ich core 1.200 volts
d-ram 2.080 volts

the temp so far is
prime 95(64c)
intel burn test (71c) max setting vista 64bit 20 passes
in games i have seen no higher that 55c

my cpu cooling is a true 120mm with 2x silenx 120mm 90cfm fans in push pull with the same type of fan as an exust
here is a site for pics i dont know how to add them

Anyone running f10f bios yet. Always looking b4 i step in the turd pile, you know how it is.

yes i posted back on this thread...

F10f runs fine, seem that they lowered some of the chipset timmings, but inmo F10b still the best...

For those that updated to F10e bios you may find it very good as with ALT+F12 on this F10f will update your backup bios to F10f and get the F10e (this bios as i explained on other posts updates your factory backup to F10e)

Cheers all

Heh does anyone know a way to measure the NB temp?

[radaja]

ill have my UD3P rev 1.0 board next week.cant wait
to have some fun with my E8400 and my cellshock
ddr1066 sticks.but soon,very soon ill have to get
me a low vid Q9650 and some g.skill pc9600's.

Loco23,has an app i think,MCHtemp?i cant rember what its called

yeah I remember vaguely about that, thanks for the specifics.

[64dragon]

hey guys, i just got the UD3P set up with my X3330 (aka Q9400). i know my chip can do 3.7ghz as i've been running there on my MIIF for a few weeks. Since i don't know the ins and outs of the UD3P i tried the EasyTune6 to see what voltages it thought i needed for 3.6ghz using the quick boost to get a baseline. when i go to Advanced and voltages, the only one that changed from stock is vcore, target went from 1.2375 to 1.3875v

Does that mean that i can run the board with vMCH at 1.1v and cpu Term at 1.2v?

[The Viper]

64dragon: CPU term might be ok, the MCH@1.1V probably is too low at a 450FSB, but that is really dependent on how much RAM you have, what divider, etc. I would do some Prime Blend testing to check those voltages out.

[pitashen]

Has anyone experiences the following? :

Tun OFF Gigabyte ATA controller
Turn ON AHCI mode
Reboot
System functions normally EXCEPT I am not able to get back into Bios setting no matter how fast I try to press "Del" Key. Leaving me the only option of resetting Bios by shorting the pins.

I usually like to turn off things I don't use, but in this case I have no choice but leaving the Gigabyte ATA controller on. I wonder if it has to do with my usb keyboard or is it just a little glitch with the bios.

[64dragon]

i figured it out, EasyTune wasn't reading the voltages correctly, i had manually set the stock voltages in BIOS and it was displaying them...except vcore. i tried to manually set 3.6ghz in BIOS and it wouldn't remotely boot at the values in screenshot above, put me into a continuous reboot and had to flip the switch on the psu and clear CMOS to stop it.

[r3p1v]

Does anybody know what the state of these boards are in the UK? They're not available anywhere, with no shops listing ETAs, yet they're still widely available in the US.

Hopefully it hasn't been discontinued here

ok i got 4.4 stable too 1.46v temps 55-67c
you gigabut gurus you think this is the max?
vid 1.25
any template to try to get more outa this quad

Well Gomer , For 24/7 opperation , probably. For benching nah, you can go further probably. On another note I just hooked up my water cooling last night. I have the pump running stil right now while I am work and will finish hooking everything else up tonight and turn her on for the first time, WOOHOO!! I took my time and ran everything perfectly. I can't wait to see my temps now.

wanna bet my air settup can beat you water settup
i was loadin @ 50c @ 4.4 with ac hookup

I think that my thermalright extreme was dieing on me so. I went up to 4.2GHz with my extreme but couldn't go over that because I needed more voltage at that point and the cooler just couldn't handle the wattage at that point but, this water cooler should be able to handle it just fine. I will stick the radiator outside when the temps drop tonight and we can see who gets further . I love competition.

with coolmaster 212 and cold air goin straight through hard to beat
you gonna have wait till it gets colder outside
my thermalright extreme is 100% but my 212 woops it lol

It was pretty cold last night here where I am at. Let the battle begin . I will post some results later on tonight when I get home and get to hook everything else back up and run the system for the first time.

as of 2am this morning i was 7.5 hours Orthos stable @3.6ghz 1.35 vcore and 1.30 MCH and vTerm, went to bed and woke up to a pc that had rebooted on me, windows error box said there was a BSOD. looks like the BSOD happened at 7am. i'm not sure what that means for the stability of my OC, to be around 12 hours stable and then have a BSOD. normally i don't have an issue if it can pass 9 or 10 hours.
