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

[xzulu]

Hey guys, I'm planning to get a UD3P and put my UD3R on my kids rig. I can migrate my setting use for my OC's with my Q9650 on the UD3P without problems right?

Thanks

I'm usin 8gb Pi 9600's and cant get them stable at 1100+. 1:1 for 8gb i think is all we can do at high FSB. I've tried everything, even a new board. No go with dividers and 8gb for me. 4gb i'm good at 1250+. To me not using a page file and 8gb 1:1 feels better than 4gb @1200+. I have real good cooling on NB and RAM.. I've just learned to live with the 1:1. I know i know just something about 8gb at 1200 is sexy...oh well. Anybody else using 8gb successfully at high fsb? Pleease chime in....

I'm willing to lower the RAM frequency if I could just get the FSB to 500, 550...I'm using the PI 8800s and they are stable at 1140 though, what was your highest FSB?

[strange|ife]

CPU Reference and MCH Reference are the GTL settings.

cool

things are coming together. I will have some screens up sometime this week.

booted @ 550 FSB for fun, memory is holding me back. But 500 fsb seems stable, memory running 1:1 @ 1000mhz

this board is pretty damn good, just hope it last.

[Machinus]

I got stable at 4.03Ghz on my Q9650 and 1140Mhz on my 8GBPI with the following settings, but I am not sure they are optimal...I am hoping someone in this thread can help me improve them Can I reduce any of these voltages or get the FSB/clock higher somehow? I have tried lowering fsb and using dividers but the damn thing will just not stabilize...

I e-mailed GIGABYTE Technical Support regarding the EP45-UD5 board and they advised that due to the performance of the P55 chipset, further P45 projects (including the EP45-UD5) have been cancelled and most of the EP45 boards, with the exception of one, have been EOLed now

sure mate but just give a try first sometimes changes

Yepper. This board and quads rock.
Did this awhile ago just for kicks..

Yes I found out Vantage doesn't count if the physx is on.
When it gets cooler here I'll do some more benching.

[maxgull]

you will likely have to lower your system memory multiplier before moving on, i am assuming it is DDR2 8500 (or 1066 speed). 1140 is a tall memory oc at only 1.92 volts.

Just taking my chip through it's paces. I'll have to say this chip is probably the best chip I've owned so far considering my weak psu and mushkin ram I'm using. Plus it was only $170.00 at the MC. Still nothing to sneeze at... Waiting on some PCP&C Silencer and some quality DDR3 and then I'll see what she's really made of.

zucker dont you think 75c a bit high lol

[Zucker2k]

zucker dont you think 75c a bit high lol

Yes.... but, I like the fact that the chip can handle the heat and still be stable. This is another characteristic (thermal) of a good chip. No?

when i was @ 4.275 i didnt like the fact that it got to 65c while priming
yes it can handle it i guess lol but for how long

Good thing I don't run linx 24/7 for my everyday use.

My humble E5200 + EP45-UD3R. The challenge was to get the highest overclock while leaving VTT and VCORE at stock.

I'm still stabilizing this thing as it fails Large FFTs or Medium Data Set on OCCT. Then I'll move on to highest possible overclock while keeping voltages within absolute maximum settings.

Memory multiplier, do you mean the memory clock or the divider? It's factory rated at 1100, so I am just ocing 40Mhz. The RAM seems to be ok at 1140, but prime failed 2/4 tests after 12 hours even though the system was still very stable for use. I will try raising the DRAM voltage and testing again...

[xzulu]

Ok, will give it a try!

I just bought one of these boards to go with my Q9550 and 2x2 Gb DDR2-1000 G-skill ram. It is rev.1.6 bios FB.
I have it at 3.3 Ghz stable now, but everytime i restart the machine or save and exit cmos it hangs and stays a black screen until I hit the reset button
Is there some setting that i need to change? Is this a common thing with these boards?

maybe try the latest bios for 1.6 rev boards

http://forum.gigabyte.de/forumdownlo...8/P45UD3P2.zip

see if that helps.(lawl thanks to statsio, i couldnt find this bios until he kindly posted it a few pages back)

but i doubt this is the issue with the booting troubles

i would try raising voltages on by .02 on the minor adjustments, and setting vcore above 1.42 bump.

maybe set the ram to 2.0~2.1 since you said you had pc 8000 gskill. doubt that has much affect since you shouldnt be overclocking the memory, unless you have the strap set funky...that could the problem fior no booting.

ahhhh started my weekend early tonight...

well its 5 am now lol...bed time...beer going back to fridge..no more.

[xzulu]

Ok, my plans of getting a UD3P for myself and giving my UD3R rev.1.1 to my kids are on hold. Cause the only available rev for the UD3P here in my country is the rev.1.6. I was hoping on getting a UD3P rev.1.1 but no more.

How different in terms of voltage is the v1.1 from the v1.6? Is the rev.1.6 much better than the rev1.1?

Thanks!

Well here is my E8400
at 4250 MHZ



and at 4500 MHZ



FPO:Q842A861 vid 1.20

I think it's quite acceptable. What do u think guys?

[kagula323]

double post ... sorry ... my mistake ...

[zsero]

Which RAM would you recommend for this board an 8 GB setup? I am thinking about this board + Q9550 + 8 GB RAM, but I dont know if it would be stable. I am dreaming about 8.5x480 FSB at 1:1 RAM. Is it possible with 2.1V RAM kits, like the Corsair TwinX 1066 CL5? If not, I think I will go with i7 920, but that woud be much much more expensive...

well i slipped my botcott is over got a ud3r
lets just hope she dont die in less than 3 weeks
first boot @500x9 on q9650
now i just need another cooler my tuniq isnt cutin it
can somebody tell me where are the gtl settings lol

go to VTT = 1,20 set .785 on CPU REF and .80 on MCH ref and then go up on VTT and let refs change auto and it will do fine
