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

[truehighroller]

found some Prime-stability at 4.2 ghz, but I had to really jack up the northbridge - jesus


edit:

managed to get the vcore down along with the northbridge a bit and still have some stability - but there doesn't seem to be any way around that vtt issue...

oh well...I guess this is what it takes...

I have mine stable at these settings.

that's similar to what i've been trying, but I keep running into the wrong references....
i'll try exactly what you did as much as i can on this ud3l and see if it allows me to lower anything like the termination for instance...

thanks

edit: i tried those settings and it gets me into windows, but i get an error about 15 seconds into the stress test...

I'll have to fiddle with the numbers some more..cause i seem to got it stable a few posts ago, but i'd like to keep the vtt down... the northbridge i really don't care about... but according to the intel document i got up to about 1.45 for both the vcore and the vtt before they "guaranty severe degredation..."

that's all folks

thanks

edit: well i gotta admit, your settings work mate, but any deviation from them and i'm instantly buggered....


oh well, thanks

[RAMMAN]

you got the Quad Extreme and all you're being allowed is 3600MHZ???
something's up - board sounds like it suffer's from the finicky-ness my last UD3R had - how bout just raising the multiplier really high????
I coulda sworn Extreme's were unlocked....
I would thought you would have been good for at least 4.5Ghz or even 4.7Ghz...

oh well...

edit: oh, sorry, didn't notice it was C0 - disregard
4.0 should be no problem though...

edit:i gotta quick question:
will too much vtt kill the chip like vcore????

Cause I can seem to get 4.2 stable enough for everyday but it appears to correction: 1.64 vtt for the Prime95 Stability Test

thanks

there is a perfectly logical reason why it stops at 3.6ghz, its on the stock cooler atm and gets to 70c. i was told by the previous owner this exact same chip went to 3.8ghz on a thermalright ultra extreme at a good 25-30c cooler at load than what im running at, so im not surprised its only 1m stable at 3.6. im assuming 4.5 should be a cakewalk with dice and with a lot of luck 5ghz might be possible.

[Gameman]

that's kind of more what i was hoping to hear...thanks

well that's enough for now...looks like i'm settling for 4.0 ghz...

there's too many variables to justify that extra 200mhz...if I want the 4.2 or 4.5 speed i'll go for the Q9650 or the QX9650 later

but for now, though, whippin the ass of a QX9770 at stock is more than good enough for me...

it may be time for the T2RSB Plus o mine to make an appearance...
i've heard some users here managed 500 fsb stable on various quads with the LanParty series of boards...

but first I wanna try the UD3P - that was the Gigabyte P45 I originally wanted...and maybe just for kicks a cheap Q8400 or possibly the Q9650....if newegg ever get's any more in..

but for now 4.0ghz Quad is plenty to be grateful for...

[Gameman]

decided not to give up after all:
I finally got it stable enough to use at 4.2ghz with better voltages...
it took a combination of all the suggestions and something else I found...
christ!! that was simply horrendous....
oh well...

enjoy

[truehighroller]

On mine if I bounce my CPU Ref around a little "up a few notches down a few notches then back to what ever middle point I pick" and keep booting in to Windows and testing with IntelBurnTest, I eventually find the middle spot that my CPU likes. That is the whole trick to getting my settings stable. After I do that if I never go back in to the BIOS and mess with anything my system stays 100% stable.

This board is kind of weird the way it does that but, it is reproducable so.. it's a fact that it works for me.. I've been on these settings for a long time now. I think there's allot of variation between CPUs and North Bridges as well so you have to take that in to consideration when going off other peoples BIOS settings. Any way with all that being said glad I could help a little.

[RAMMAN]

now im going for 24/7 stable that will boot out of the bios, right now on 400x8.5 1:1 3-3-3-8-33 pl7.guess i should try for 425x8 out of the bios but i dont know if i will be able to keep the 3-3-3-8 timings or the pl7 and while it will clock far in windows it doesnt seem to like booting from high fsb.

[RAMMAN]

i dont suppose anyone has a template for ddr2-1300 with micron d9 and a ud3 series board, preferably on the 5:8 divider? there must be something im missing. 1200 5-5-5-15 2.2v is stable but im hitting a brick wall in the high 1200s. 1300 5-5-5-15 pl9 2.4 vdimm 1.3 mch 0.8 mch ref errors just seconds into orthos and trying 6-6-6-18 pl10 had no effect on stability. i havent touched any of the drive strength or clock skew settings, maybe thats the key?

[In-Fluence]

I had a similar problem when benching. My reapers didn't benefit from any looser timings at anything over 1296MHz 5-6-5-15. One thing that did help was to run 5-6-6-18 which got me benchable at 1300+, but it didn't like 6-6-6-18 at the same settings. Maybe worth a shot if you haven#t tried already

[the_real_7]

Got some bad news
My tx850 power supply just died yesterday !! And damn was really looking forward to pushing those g skill 9600s but now im also finding out that the revision of this board which I have 1.1 doesn't like a lot of dividers so its may not reach the oc I want but good news is I bought a hx850 for the meantime which will good future proofing

there are more settings in there that i know wont work for me than i can count. i have given up on getting high memory speeds because my board really doesnt like straps other than 333, that and the max fsb of 450 the only way to get ddr2-1200+ is with the 5:8 divider and being limited to 400fsb is not a good thing.

im going for raw fsb numbers now, 450x7 is orthos stable at just 1.2 mch 1:1 4-4-4-12 pl10. 475fsb still locks up in orthos 1.3vtt 1.3mch 1:1. tried 1.34vvt and pl12, no luck. but the one thing which stabilized it at 475fsb in the past was mch ref i believe. im not game to raise mch core higher than 1.3 even for benching, as it is at 1.2 mch the northbridge heatsink actually heats up the memory stick in slot one, but not the one in slot 3 of course

I run mine at 1.52 and it's fine with a fan facing on the it and the memory. I think you are being to scared here. You need to stick a little fan in there facing right towards it and the memory and crank up the voltage some. Take off the heatsink shield crap to while your at it otherwise you will be just spinning your wheels.. While I'm schooling here you need to make sure that your CPU Mosfets right above and on the side on the CPU socket aren't getting hot enought to cook your finger while you are at it because they will get that hot.

[Gameman]

that's what i was thinking...
I used to give my T2RSB Plus X48 Northbridge 1.52-1.72 and it never gave me any guff...and it's stil alive and kicking today - in fact i'm going back to it tomorrow...

for my 4.2 the other day I just accepted that it takes a modest 1.56 v on the northbridge to keep it stable for that speed with no errors... just make sure theres some sort of fan on it...
i don't know about the mosfets or mofsets or what ever their called but i don't expect much for a $100.00 board...

if they go I'm afraid them's the breaks....

[RAMMAN]

turns out 450x7 5:6 pl9 boots just fine and is orthos stable, apparently there is a fsb hole at 400fsb exactly so it wont boot at 400fsb unless its 1:1. i suspect setting 400fsb and a setting other than 1:1 changes one of the subtimings to something that simply doesnt work, possibly tref. 400 1:1=3200t=stable so perhaps 400 5:6=2600t or 2080t=no boot, who knows, maybe 400fsb and divider other than 1:1 sets it to 1t lol. i know i can safely use much higher mch core if the nb was cool, but it gets burning hot to the point where it actually heats up parts around it.

case is an aluminium coolermaster cosmos s, 1x 120mm front intake 1x230mm side intake 1x120mm rear exhaust 3x120mm top exhaust.

btw for 1.24 mch whats the best mch ref? 0.8?

what do you mean by heatsink shield? im confused.

Again and I mean nothing but respect here.. Put a fan on it.. You are killing your memory and mother boards life span by not putting a fan on it.


@Gameman,

Glad to see you got that 4.2 you were aiming for, hope my settings helped you a little.

[RAMMAN]

i do have a spare 120mm case fan but nowhere to plug it into, i would have to unplug the 230mm low speed side fan that came with the case. any tips on how to position a 120mm case fan inside an upright case so it covers northbridge and preferably ram as well? pics would help. keep in mind the crappy nb hs that comes with the ud3lr will limit the effectiveness of active cooling.

perhaps im overreacting, while the northbridge heatsink is definitaly the hottest part of my rig i can actually touch, at no point has it ever been hot enough to burn a finger even over time.

ironically the stock intel hs is actually keeping the mosfets somewhat cool, not as cool as the memory but not as hot as the nb hs either. i wont have that advantage when i get the guts to try my koolance dice pot though.

[truehighroller]

Yes, I know it's dusty and I'll be cleaning it tomorrow. I have two cats and a dog . Notice the little fan on the mosfets right above the CPU. When I touched that heat sink after testing with intelburntest it was hot enough to almost burn my finger.

I put that fan on there and the problem was solved. I was also having random lock up issues before, I put that fan on there I will add.. Notice how I put a piece of cut cardboard on top of the screws for the heat sink on my video card and even put a piece of velcro tape to help hold the fan in place . That my friend is called improvising.

[RAMMAN]

anyway i think i have found a 24/7 setting im happy with



pl8 1.24 mch core 0.8 mch ref 2.2 vdimm all other voltages normal. i could have left mch core at 1.2 and mch ref at stock but i know from past experience that would put it at the edge of stability and i dont want to risk getting a lockup after say 1 hour of gaming. pitty i couldnt stabilize 1080 4-4-4-12 with a reasonable voltage so stuck at 1080 5-5-5-15 2.2v even though im using team xtreem 1300s :/

so when i get to trying dry ice benching with unlocked multi is it as simple as raising cpu vcore, cpu multi and vtt or am i being naive?

edit: i almost forgot, by default its booting with read to write delay, also known as trd_wr at 9 instead of 8 which is affecting bandwidth numbers considerably and i had to set it to 8 with memset.is there a setting in bios to get it to boot at 8 instead?

[Gameman]

@Gameman,

Glad to see you got that 4.2 you were aiming for, hope my settings helped you a little.

No, seriously they did...I'm using a combo of a few of your settings along with what I found to be comfortable voltages and it seems to be cool enough...

I'm coming from an E8600, so I'm used to SPEED, and 4.2 is in the E8600 range...but I wanted the extra cores and 12mb cache for Photoshop and virus scanning while working, not to mention shaving a few moments off of my XviD encoding time for my DVD collection... so i think it was a smart very reasonable 300 dollar investment.. I just would like to have it running at somewhat safe settings and still last a year or two if I needed it....

the motherboard, I don't care so much about though...I have the T2RSB Plus sitting by and to replace a Gigabyte p45 ain't all that much...

[Gameman]

just manage4d 4.3 ghz stable enough for everyday use...but things are getting kinda hot now - cpu is at 50 idle - I can definitely see the case for h2o cooling...
may keep this may not... I haven't decided...or i may just grab a QX9650/Q9650 and go all the way to 4.5...
I imagine the q9650 would probably be better because of the E0 stepping????

anyways thanks

[Jupiler]

Very nice result, although I'd back down with the voltages, specially CPU PLL and VTT. You risk killing your chip.

[Gameman]

thanks...
i'm gonna have to work on this over the next few days....
but it's looking like the Q9650 for me next...

got it down a little bit - but haven't given it any kind o load though....will see though....


edit:still more though this is probably about as low as i can go...i'm surprised i even got in...


oh well...thanks

enjoy.......

[truehighroller]

Your welcome and my Q9550 is an EO stepping and so is yours. Look at your screen shot with CPUZ listed above, it tells you the stepping you have. Fact is that a Q9650 would be just as hot, it just gets hot at these speeds. I run 32C Idle with my water cooling setup and 65C full load with Prime95, 78C full load Intel Burntest.

[RAMMAN]

my board used to be able to do 1200+mem speeds together with 450+fsb on the 3:4 divider 400 strap. used to get read, write and copy speeds all in the high 9s as well as latency in the low 50s. one day it wouldnt boot, this was a few weeks ago. since then it refuses to boot 3:4 400 strap no matter what i do
