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

[OC Nub]

which P35 do you have?

Its an old P5Kdeluxe but did really well with my e8400 CO.

[motopen1s]

Hey guys, I am doing a build for a friend of mine based on EP45-UD3P.

Specs:
Mobo: EP45-UD3P (updated bios to f9)
CPU & Cooling: E8400 (E0), Ultra120 Extreme
RAM: 4gb Mushkin (996580) DDR2-800 4-4-4-12 (the kit have been already tested in my build)
PSU: Enermax Pro82+ 625W
Sound card: Auzentech X-Fi Prelude
GPU: GTX260 216sp
Case: Cooler Master HAF932
Drives: 1x Raptor 150 (OS Drive) on SATA2_0, 1x 320gb seagate on SATA2_1; DVD Drive on SATA2_5
OS: Vista Ultimate 64bit SP2
Mouse & kboard: Logitech g5, connected through g15

There seems to be couple of problems:

1) The system does not detect X-Fi Prelude (tried both PCI slots). When installing drivers there is a messege saying 'multimedia adaptor is not found' (something along these lines).

I've updated bios to F9 through windows using gigabyte utility; loaded optimized default settings. As mentioned the card is not recognized in both PCI slots.

2) One time I got a blue screen which mentioned USB devices (dont remeber the exact name of the error now).

3) I've pluged out the Prelude and decided to test for stability. OCCT 3.1 linpack test blue screened after a couple of minutes.

All tests were made on stock clocks, the bios seem to set vRAM a little low at default (1.8v), so I did change it to 2.0v (default for this kit).

4) I've noticed that the bios lowered the multi to 8.5, so that I had to set it to 9 manually.

My ideas:
1) it seems to me the I might have to mess around with PCI IRQ settings or IDE/AHCI settings (?).
2) Trying appling voltages manually for cpu, ram, nb & sb. Disabling all energy saving/throttling options.
3) Leaving only one stick of RAM, 1 HDD & DVD drive and gpu only. Trying to flash bios one more time (not through windows this time around). Maybe even OS reinstall... Basically - possibly spending loads of time.

I hope you can share some of the ideas and settings & help me to find out possible tricky moments with this board.

4.45ghz 7hour+ prime blend. Had to set MCH ref to .74 then go up to 1.30v VTT. This is way more vcore than I'm use to using but its a cool running chip, will leave it at 4.45ghz for daily use, otherwise it would end up in a drawer with a couple other less than desirable clocking CPU's.

Motopen1s, I'm sure someone with more knowledge than me in this thread can help you with the problem you're having. Looks like it will be a nice rig. BTW the bios will auto set the multi to 8.5 until you load optimized defaults or manually set it, that is normal, also set first init display to PEG in advanced bios features.

I may just need to RMA this board again. It is really odd though. Dual channel won't work at all, but I can run single channel and overclock the hell out of my processor. I have got it up to 4.6ghz on air...not prime stable but I gamed on it for 2 hrs.

I like the board, I like the overclockability of it and I really like my set-up. I however want to get my 4 gigs going and I really don't want to do a complete reinstall again.

Yeah, looks like you need to. And yes, if it doesn't want to run dual channel, you must have a damage memory controller or could also be the dimm slot.

Yes, this board rocks!

[stw500]

Well I dont have so much luck with my CPU, E8400 E0.

Doesnt matter what settings, its not stable in prime custom over 4,1 GHz. Seems to be the limit. thanks Radaja for your settings, but it didnt help at all.

One hint for all, dont use LLC, it generates peakes which can kill your CPU by time. These hints can go over the maximum volt allowed for the cpu.

[bluestang]

I was able to lower vcore from 1.40 to 1.375 in BIOS. and was able to raise FSB to 510. Everest mem scores at 10435read/10847write/10821copy/50.3lat. What do you guys think of IntelBurnTest? Better to use than Orthos/Prime to check stability?

[OC Nub]

I like LinX for a quick test but never feel that its really good enough until it is minimum of 8hours Prime blend stable. I failed Prime at 8hrs 5min yesterday when I went to open CPUZ for a screen shot and again this morning at 7hrs 55min at 4.45ghz when I opened Mozilla, but surfed the web last night for hours while Prime was running. So I guess my 8hrs is good enough theory has some holes in it but that's what I did up until now. Everyone has their own method they use to feel comfortable that its stable enough.

BTW good job with your 8500.

[18 is # 1]

Well I ordered mine from the Egg today. My Abit Pro seems to have gone south. I'll be using an E8400 EO and am anxious to see what my new LV Blades will pump out.

[radaja]

18 is # 1,your going to love your new board
and this thread is a great place for help,to help and just to share
i cant wait to see what those LV blades can do,keep us posted

bluestang,ive never been to comfortable with excessive stressing.
two hrs prime95 blend/orthos blend and 20 runs of LinX/IBT tops.
and Memtest in windows 100%-200% coverage.i know some people
might say im not 100% stable,they're probably right but its still
good enough for me.as long as my computer doesnt crash( it hasnt)
with the amount of different OC's i try,i dont see why i should kill my hardware
but thats just my humble opinion and the way i feel
your going to get alot of different answers about this,its really what ever
you think the answer to this question is/how stable is stable?

[bluestang]

OC Nub and tadaja, good info and thank for the advice. BTW, how did my temps look for the IBT 20 pass?

[radaja]

temps look good for IBT

[xzulu]

Like what radaja said....You're going to love this board....

OC'ing with this board is so easy compared to other boards I've used.

[xzulu]

OC Nub and tadaja, good info and thank for the advice. BTW, how did my temps look for the IBT 20 pass?

Your CPU temp was just fine. My CPU temp when I did 20tests reached 75C at 450x9. LOL! Passed!

[OC Nub]

OC Nub and tadaja, good info and thank for the advice. BTW, how did my temps look for the IBT 20 pass?

Real good temps for IBT.

Hello All,

I have been running at 4 GHz for a couple of months now with out any issues.

Recently when powering on from a cold boot, the system will crash at the loading windows screen and then load the default BIOS settings.

When I go into the BIOS the red dialog box will be there stating that the BIOS isn't stable.

Can you please help me figure out these issues?

My systems specs are in my signature.

I have posted my Template below.

-Jsunn

first try upping your vdimm one notch ,see if that works.if not put it back and try the vcore one notch

[OC Nub]

Jsunn, I would lower the PLL to 1.57 or less.
Have you made any hardware changes? I added a second gfx card for cf and my oc became unstable at the same voltages.

[radaja]

i didnt even notice that,good catch OC Nub.definetly lower pll to 1.57 or even 1.50
when i got my first set of cellshocks,i was afraid of giving to much vdimm,and had that same problem.i was 100% stable at 8.5x500@4250 ddr1200 pl8
it would restart just fine,but when i shut the computer off and started it it would reboot with defaults and go to the red OC failure screen.if i set pl to 9 it worked fine but to keep it at pl8 i had to raise the vdimm.after that it cold started everytime fine.

[OC Nub]

I noticed that everest and cpuid HW Monitoring programs read the Ram voltage at 2.06v when set to 2.10v bios, raised it to 2.12v and reads 2.08v. I remember reading a post, think it was by Jor that this board undervolts the ram.

[rubber5]

i have to ask for everyone overclocking over 1ghz what life will you get from your cpu in years or dont you know since you will have the mony to upgrade all the time.
I really want to push my Q9450 to 4ghz from 2.66 but i want my cpu to last 3 years or more
but i think my memory might be holding my overclock back @3.5ghz my memory goes to 875mhz but i dont really like pushing memory over its normal speed
any ideas on what i can do to keep the memory @800mhz (stock)
please let me know on what you have found if you dont mind
THANKS
love the overclocking i love this web site

[bluestang]

I was able to lower vcore from 1.40 to 1.375 in BIOS. and was able to raise FSB to 510. Everest mem scores at 10435read/10847write/10821copy/50.3lat. What do you guys think of IntelBurnTest? Better to use than Orthos/Prime to check stability?

Well, I thought I was stable! (I made those changes above in ET6...FSB to 510 from 500 in BIOS and MCH to 1.34 from 1.30 in BIOS). After leaving it this way all day I shut it down last night. When I started it up this moring...BSOD error with ntdll.dll. Thought maybe ET6 changes from last night was the culprit even though I don't have it set to start or load on startup, so I rentered BIOS and loaded my 8x500 stable setting and booted fine. Left for work and wife calls saying it locked up while surfing web. Had her hit reset switch and then a loop reboot started happening. I then had her turned off power and it reset booted and went into BIOS and told her to load stock settings. Hopefully it's good for the day until I get home.

This is frustrating. Is there something with cold starts that is screwing with it? Or should I just leave it on 24/7 and waste energy/money? Also, is there a big difference in performance between PL 8 and PL 9 ? ...as it looks like PL 9 is more stable for everyone.

[Osterman]

Me again, now I have the settings for a 100% stable OC on my CPU.

After this suggestion:

That what I do, the ref's will increase automatically as you increase the vtt. start out with the vtt at default-1.20, set the refs .760-.785 cpu ref and .80 mch ref. then raise vtt but dont raise the refs after that. Those two are linked to the vtt.

But I will se if I can touch a little bit more the ram, without touching CMD which has made me a headache.

[bluestang]

Osterman, have you tried 4.0ghz by using 500 fsb x 8? Also, why is your command rate at 1...set it to 2. That should solve your ram headaches! Might also let you get your PL (Static tRead) down to 8. That with ram at 1:1 for 1000 mhz should do you much better at 4.0ghz. Just a thought. Nice OC! and good luck!

[Osterman]

My ram headaches now are solved vecause of the CMD, it was on 2 and when I set it on 1 everything works properly.
Sorry If I didnt make me understand in the las post.

I will try 8x I think on weekend, now maybe I would touch a little bit the ram.
Also with PL on 9 wverything works fine.

But as you know this is a never ending story (like the song... I think) I try some settings, then others, and others, and others until you cpu dies (?) (joke that part about dying)

[bluestang]

Yes, the CPU dying part is not funny!

I still need to get off my a$$ and replace my thermal paste with Arctic Silver 5 and then stock fan on my cooler with a Scythe S-Flex SFF21G. If the damn SOB would only quit screwing with me after thinking I have it stable I can move on, but NNNNOOOOO why make my life easy!
