i found F4 to be best with my Q9650 and UD3P.i've only tried F6 and F9 for my UD3R.
but they all behave pretty much the same for the most part,so try the one thats on your board now
and see how it goes.
also i found that my E8500 needed less vcore with my UD3P than it did on my Asus MIIF.so you never
know,maybe you'll get 4500 with less than 1.50v:rolleyes:
good luck getting set up:up:


today i tried for 8.5x530@4505 ddr1272 pl8
it only needed one notch increase in vcore
from 9x500@4500,which i thought was great
for using a lower multiplier and higher fsb.

Hey, that are some nice results ! You just keep on going :)

Seems that I need to set tRD 2rd and tWR 2wr manually. If I leave it on [ Auto ] the board sets it to tight for PL9
Loosening those settings gives me a lot of stability in return.

ive never really checked what setting the board sets.great to know for when
im on the edge of stability,to be able to loosen these up and be stable is a +
in my book.thanks

today i decided to give 550x8@4400 ddr1320 pl8 a go,and it wasnt easy.but i got it.
i tried all sorts of voltages,some that i knew were not needed,and were quite excessive.
everything i tried failed blend before i could even hit 10 minute mark.finally i took a step back
and looked at the facts.voltages were not going to solve it.and decided to raise my mch ref
up one notch and bingo,problem solved.i guess 0.70 (showing in ET6) is ok up to 530fsb after
that 0.720 (showing in ET6)is whats needed.at least for me.later ill try and see if 0.720 will work
ok with my OC's below 550fsb.
anyways i got this one today.

going to try for 8x563@4504 ddr1351.but i doubt i can do it.

Having issues with my UD3P board. Restarts on any setting other than default in bios. Windows bsod's if Im able to get that far. Tried these things, different ram, a different video card, HDD, really thought it was my old SilverStone PSU, so I went out and picked up a new PSU, basically tried all new hardware and still the same thing. Im guessing the mobo took a dump. Have another UD3P but this was on my main rig which now has my old P5KDeluxe in it. Any thoughts on what else it could be other than mobo? Also re-flashed the bios.

Also put the CPU that was in it into my other UD3P and oc's like a champ.

maybe try taking the battery out and leave it out overnight.
sometimes thats all it takes.i had a similar thing with my dfi P35-UT-TR2S.

When I first got this UD3p board I hated the large number of settings. Now im trying again with my P5K board and its almost like you have 2 options, vcore and more vcore. Cant believe I liked this board before trying the Gigabyte board.

Thanks, will try it tomorrow when I put it back in. Was getting frustrated so I put the asus board in.

I think it must be a case wire grounding out, the asus board started flaking out now also.

Just a quick prime run to get a baseline for the new lv blades.

@radaja

You got some awesome combo there with that EP45-UD3P, E8400 and those Cellshock. :yepp:

That FSB 550 4,4GHz ram @ 1320 are outstanding, awesome work. :up: :clap:

Keep up the good work. :)

Hey guys,

Got a problem with my UD3P.

I was rebuilding my WC loop.
After reinstalling all hardware, I booted up my rig yesterday, all turns on but the screen stays blank.
Rebooted several times, Phase leds from the board light up but nothing happens.

Took out the videcard, reseated it, installed another CPU, tried 4 different memory sticks, removed the HD's from the SATA connectors, CMOS clear, battery out, but still nothing.
The system boots but nothing happens, screen stills stays blank. Phase leds turn on, and go out after 15 seconds.

What I noticed is that when I took out all memory and booted without sticks, the system would do endless reboots after a couple of seconds.

Did anyone experienced the same problem before?
I only have the board for 3 weeks now and didn't have any problems so far.

Any pins bend ?, too much pressure on the socket ? tried mobo with an air cooler ?

How much less exactly?

Have you tested the monitor? I have had similar expeiences, and it usually turned out to be a poor connection where the monitor lead fastens to the Vid Card.

hey CryptiK,were you been lately?well here are the closest examples i could find.
mind you,i dont know if you remember,but my first maxII was borked.very low voltages
vtt and nb too high and it wouldnt boot.and i never got much time with it after the
first RMA.because each board had to be sent back.so maybe with more time with it
i might have been able to lower the vcore?i dont know.

Glad to be of help. Settings it manually really makes a difference on my system. Still have to figure out which timings exactly are being set with the Standard, Turbo and Extreme settings.

That are some really nice results you have there. Never would have thought that changing the refs would help. For the most cases, once you have've found the 'golden settings' you don't have to change it anymore. Nice to see that it still can help you get higher FSB, when upping voltages doesn't help anymore.

Concerning me just not getting 4500 stable... I'm beginning to suspect my PSU. I'm running with an OCZ PowerStream 520W and a Thermaltake 450W VGA PSU. So my two vidcards can be left out concerning the powerdraw. The OCZ 520 however has one 12v rail rated 30A, perhaps I'm just on the edge here. I'm thinking of getting a Corsair HX1000 which has two 12v rails both 40A each :P

I took a look during Prime and Linx with Everest and now I also understand why LinX produces a much higher heatdump:

LinX : 136A and 196W
http://www.plaatjesupload.nl/bekijk/...368957-320.jpg

Prime Large FTT's : 100A and 145W
http://www.plaatjesupload.nl/bekijk/...370984-190.jpg

LinX draws a lot more amps than Prime so it seems

No pins in the socket bend, tripple checked it. :)
Installed the WC 3.0 and applied pressure as suggested by WC, I even used less pressure.

Even tried booting without monitor cable attached, no go.

Guess I'll be pulling the rig apart (again) :mad:, and install it again.


The weird thing is that when no memory is installed, the system makes continuous reboots (after a couple of seconds, screen stays blank though), and with memory installed, nothing happens.
DIMM slots maybe damaged, although I don't see any physical damage to the board in general.

I've been busy with other stuff, I haven't done anything bench/OC wise in a few months now. Not sure if I'll get back into it or what at this stage.

The vcore difference is not insignificant, strange that the 6 phase PWM of the UD3P seems to produce better results than the 16 phase PWM of the M2F. Of course it could just be flakey board or not fully optimized settings in case of the M2F though as you suggested. Thanks for digging those pics up.

Tried with another vidcard ? A friend of mine had issues with his P45 and the GTX280. sometimes the mobo just wouldn't post. I made a good deal and got his 280 for my 260 :)

Sorry for the late response.

I had some fun with my Rampage Extreme/Q9650/4x1 Dominator 1800C7 and participate in a Hwbot challenge over at OCN and now I have fired up a EP45T-UD3P so the EP45-UD3P have to rest until those 2x2 OCZ Blade LV get avalible here in Sweden.

BTW, those Crucial you have, what kind of IC do they have, those Crucial that i get here i Sweden have Micron D9KPT and are Dubble sided?

That´s probably due to the 2oz copper layer in the PCB and/or maybe the P45 rev A3 chipset, I bet my :2cents: on the 2oz copper. My MIIF couldn´t stay with the UD3P when I push my Q9650 for FSB 500+ and 4x2 ram.

OMG THIS CPU RULES 9x500@4500 w/1.29v
this morning i decided to try 9x500@4500 again
this time using the new mch ref of 0.720,which allowed me
to go above 530fsb yesterday and for the hell of it i decided
to start with the vcore two notches down from my last stable
vcore setting of 1.337v bios/1.31 cpuz load for 4500MHz.
so i set vcore at 1.325v bios/1.29v cpuz load.and got this:D:D:D
this cpu is a gem:up:

i was so excited and stressed about it failing that i just had to
stop it before it had a chance to fail on me.so i stopped it and
got the SS.later i'll try again to see how far it will go:D

Got an old X1900XT laying around here, gonna try that one.

Stupid question :

As I have a waterblock installed on my GTX260, and don't wanna remove my whole WC loop, is it possible to leave the card in one of the PCI-E slots (without the PCI-E connectors attached, and install the X1900XT in the other PCI-E slot?

CrytiK are you going to totally give up OCing?
"Not sure if I'll get back into it or what at this stage"
from your statement it sounds as if you have found
something else to do.
if so,the community here at XS will be losing a top notch
member who's helped a lot of users.so i hope its not so.
otherwise XS will be losing a great asset for sure.

Do you have a HK block on the vid card too? Could very well be that.
