So I should put CPU REF on .760 or .785 and MCH REF on .800, and then reise vtt without thouching those REF settings??
And always keeping mch ref 1 or 2 notches over cpu ref..
??

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.

Put the new e8400 back in, running orthos at 4.4ghz. Voltages are high but temps are good considering the amount of vcore Im using . Really want a 4.4-4.5ghz cpu for daily use even if its short lived lol. Will work on getting vcore down later.

Same here, I use LLC too

Nice! Congrats! You got a nice batch dude!

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.

Hi Panging, I don't post in this thread for a while because I play around with P5Q -Deluxe , but eventually I 'v been sold it and buy new UD3R Rev 1.1 ,and wanna share quiet stable result ,one thing that I think this is the really great for this board is it can do PL 9 with FSB 550 1:1 Dram that It cannot possible with P5Q Deluxe even boot up. then get the great score on EVEREST! and Winrar Extraction without CRC Error.
I feel that 550 FSB doen't need high VTT like I setting it only 1.20
If I set it over around 1.24-1.26 It 'll become CRC error on WINRAR Extract with unknown reason.


And anyway I still don't know why I can't OC well with my Ud3P??

Hi BuGjAE, nice to see you here again
i never owned or used any UD3P board but i assume the 2 boards UD3R and UD3P is about the same in terms of overclocking ability,
i think your new board probably worked better than your previous one.

Nice!! Another great OC! and nice chip!

Thanks xzulu.



anyways, here's my current max CPU-Z validation on Q9550 4726.25 MHz (556.03 * 8.5) Air true / EP45-UD3R / DDR2 G.Skill 8800 Pi 4x2GB

Nice coop!

[radaja]

Coop,very nice score

pangingIII,awesome OC on your 9550

[radaja]

well i took matters into my own hands.instead of waiting to buy a new true,i
figured out how to mount
my mini-typhoon on my cpu.i had to file down the corner,cause it was hitting one of the capacitors
(it mounts from corner to corner).but it paid off
15c-20c drop in temps
this exact same OC,the temps were hitting 65c-67c and i had to stop it.
but now as you can see temps are great


i might be able to run LinX or IBT now,maybe

[OC Nub]

Nice temps radaja.

Was able to get vcore down a bit. Just before posting this I got a bsod at 8hrs 5min Ortho's while opening everything up to take a ss . Took this ss earlier this morning.

[radaja]

thanks.i kept putting off modifying the mini-typhoon cause i never thought i would get these kind of results.
when i had the intel stock cooler with the 92mm 4500-4700RPM fan on top blowing directly down,i didnt think
the little extra surface the mini-typhoon had would make much of a difference,but it's all copper and has six
pipes,so i guess it really does make alot of difference.
by the way nice OC

[pangingIII]

pangingIII,awesome OC on your 9550

thanks.
that's my very first UD3R, bought it since it's first release, it's still working 100% like new.

[OC Nub]

Great job PangingIII with your 9550.

[pangingIII]

Great job PangingIII with your 9550.

thanks.
i may as well mention that the CPU is a used cpu, from some oem machines , i think.
i bought a couple of them and they turned out to be quite good overclocking cpu's, at least what i think they are.

[radaja]

well heres a comparison with my new cooler setup.
the first one i had to stop at 8m cause the temps hit 67c


and now it never goes above 50c

[OC Nub]

Doesn't look like you even need the Ultra 120.

[radaja]

nope.
thats exactly what i was thinking.

[coop]

xzulu, oc nub, radaja, thanks. It used to take twice as long even with dry ice for 32m. I did that so many times,
I think it did something to me
radaja, that is a great relief I'm sure. excellent payoff for a little work. pangingIII, really nice job.

[OC Nub]

What is the maximum voltage you guys feel safe using for MCH 24/7 use? Im at 1.340v ATM but will need more to go any higher than 4.4ghz. I use this PC mainly for gaming. What doesn't make any sense to me is at under 1000mhz using 200d pl9 I wouldn't think it would need much MCH voltage on ram rated for 1066.

[clo007]

very nice BuGjAE!

clo007,have you tried a new set of ram?i mean a set that you havent tried on the previous three boards.cause i cant believe you have had such bad luck as to get three boards with the same problem.i know you have tried several kits of ram,but have you bought and tried a brand new kit.i can send you my cheap ddr2-800 g.skills that work great on my new board,they OC to 1066 with ease.no charge.i'll give them to you.just pm me your shipping info.if your interested.it's this kit in the link below.
http://www.newegg.com/Product/Produc...82E16820231098
LMK ok.

That'd be sweet man. I will send you my info. If they work, I will give you some coin for them. If they don't, i'll ship them back.
I have tried 6 different sets of ram...2 sets of ballistixs, 3 sets of gskill, and 1 set of Corsairs. I honestly am not sure what the deal is.

Hey dude, nope I never had problems at all. Stable as a rock.

I just had to set the vdimm in the Bios to 1.92v cause in windows it runs at 1.89 if i set it at 1.9v in the Bios.

What problems do you encounter?

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.

if you have a fan on the NB,i would think that up to 1.40v would be fine for 24/7.i have mine at 1.36 for 9x500@4500 ddr1200 5-5-4-12-30 pl8.

well this cpu is definetly great.9x500@4500 w/1.32v



everest

[OC Nub]

Yeah I have a fan right on it, so should be ok.
Looks like the typhoon is pretty damn good! Thats an awesome chip you have there.
I took my 8400 out and will try it in my p35 mobo to see how it does compared to this.

[radaja]

which P35 do you have?

[EliTE22]

thanks.

any chance i can get ur bios settings? please
what ur max fsb so far? i got to 565fsb so far, hoping to get 568
