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

I see you running RAM PL8 try to increase MCH core around 1.38-1.4 may be help. If cannot pass you need to run PL9 test stability, and also try set this

CPU Clock Drive...........................: 800mv
PCI Express Clock Drive...................: 900mv
CPU Clock Skew (ps).......................: Auto
MCH Clock Skew (ps).......................: [150PS] <----This can help stablity while using High FSB

What strap are you using? Try "D" it can be relaxing your ram timimg more than "B"

Anyway If it's still can't boot let post your Bios setting

radaja,

Can you please post all of your setting for your second rig?

RIG #2/ EP45-UD3P / E8500 eo / G.skill pc8800 / Radeon 3870 / Antec 550W / True120 / Case? /

This is pretty much the exact system I am building.

Thanks for your help!

This is with the Ref that is shown in ET6, they are the most stable for me at that FSB.

I've just gone ahead and picked up a EP45-UD3R along with a Q6600 and a Dominator 4gig kit of TWIN2X4096-8500C5D. In route from the egg to arrive tomorrow. I plan on using my D5 pump, BIX-II Dual 120mm Rad, 1/2" with a new Swiftech GTZ block. Pretty killer I know and less than $450. Along with the boost my 280 will get I'm stoked. My old OCZ ddr500 is on it's last leg and gave me the excuse I needed to finally upgrade. It's to be my 24/7 main rig for gaming and everything else. I've spent the better part of the week reading and prepping as I haven't touched a single 775 board yet. I'm looking for around 3.5GHz.

I'm only on page 27 and about to pass out and wondering if someone could advise me on the best BIOS to use for now?
What the difference is from EP45T & C to EP45?
If I may encounter any issues with the components compatibility?
I have a bunch of extra mosfet heatsinks and little fans, anything you guys might suggest I attach them to?
Thanks in advance for any answers.

Finally i want to make this as my 24/7 use..is it ok?

Not bad for 24/7.

Can you post a pics with ET6 with your volt setup?

1 Attachment(s)

Ok bro.,this is it..

looks great for 24/7. very good volts

Guys is there any way to get the same effects of raising the vcore, i dont want to go above 1.5 actual windows vcore but i may need a tad bit more voltage to get my current FSB stable? I have vtt and pll at stock settings. Thanks

Please, need some help to make my settings stable... I can boot, use windows normally, but this morning i went to work and leave ORTHOS running (Blend test) when i come back my computer had a BSOD and now i don`t know which settings i can change... any suggestion?

Is anyone aware of / have comments on new beta BIOS f7b for UD3P?
http://forums.tweaktown.com/f69/giga...est-bios-28441

i took off the covers on the heatpipe assembly and replaced the thermal grease with arctic ceramique and now my temps have drop by about 4 c.motherboard sensor used to be about 16-19 c at idle now its 13c at idle.http://i40.tinypic.com/30kx4hz.jpg

First overclocking attempt on a Q9300 with EP45-UD3R board, with the very first BIOS setting to boot the CPU at 480fsb, i was not even sure the system would boot into Windows.

PLL 1,50
VTT 1,30
CPU ref. at around 69% (of VTT 1.20v)
MCH 1,30
MCH ref. 69% (of MCH core 1.10v)
Vdimm 1,90
DRAM VTT, Channel A/B ref. and DRAM/MCH ref., all set at 45% (of Vdimm 1.80v)*

*this setting may not be working with a different ram kit,
D9's based memory modules might not work at all with this setting.

4 instances of SuperPi 32M test only

@ezaleina, looking where good for a 24/7, nice done :up: :clap:

I should quess you need to raise your MCH Core, run 4x1 ram are a bit stressful for the MCH, raise 0,02v at a time and retest.

Set your CPU Ref at 0.760 when CPU Term are 1,20 then set back CPU Term to 1,30, don´t leave it at auto.

Installed here. for now nothing different. Didn`t test all settings.

You again Ghostleader, lol, help me on other forum, and now here, so let`s talk about it.

Updated my bios to F7b. Still running 500x8 but different settings:

CPU Vcore: 1.33750
CPU Termination: 1.280V
CPU PLL: 1,50v
DRAM Voltage: 2.140
CPU Reference: Auto
MCH Core: 1.30v
MCH Reference: 0.750 (ET6 = 0.700)
ICH I/O: 1.50v
ICH Core: 1.10v
TRFC - 48
PL - 9

And rest is the same. My question is. How test my stability? Which program and how long time? Orthos? Intelburntest?
And if it fail? What change? Rise some voltage?

Thanks!!!

Not sure if has anything to do with a fresh install of windows or the 7b bios, but my occt voltage values look normal. I put both on at the same time so I have no idea if one did it or the other (see first page for occt voltage fluctuations)

this particular Q9300 required quite a bit vcore volts when it's at 500fsb the CPU is also so hot and my system is an air cooled overclock so i can't do much more than just running a superpi32m test. it's time to find a good quad E0 stepping CPU.

Tq so much bro.,it happens because of you and others guide.,which i learn lot from here..tq..:yepp:

I 've been flashed to F7b. And I think this BIOS is much different form the other,I got a lot of unstability which all same setting that I do in previous.
Anyone can tell what is improving? share your BIOS setting especially Core2Duo :D

I doubt for a long time why this board need to adjust MCH reference to get prime stable? It should be left to Auto like the other board... I use 0.68 MCH Ref with 1.26 VTT to get pass extracting WinRAR archive. but for this setting I can't run Prime95 then try to MCH Ref 0.70 I can run prime95 but got CRC error in extracting WinRAR.....finally I still not reach to stable point:(

Here are my new everyday settings E8400 @ 4.1 GHz H2o my goal is 4.2 GHz, I will later test times
PLL cpu, v-core could be even slightly reduce my ich.H2o passive are not lüfter.speicher OCZ Reaper PC8500
