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

Hello everyone, long time no talkie..

Something strange happened while running 4 instances of memtest in windows7 today. Ive been having what I think is stability issues (random restarts, no BSOD). Using MCHTemp 1,21
Beta, my MCH temp climbed to max of 92C!!!! Is it just me or is that way to friggin high? How accurate is that program?

The only thing I can think of is I got a new case and am running with my side window closed and I changed from a CPU Heatsink to the Corsair H50 (fan as intake). The weird thing is that
there should be plenty of turbulence in the case to keep MCH cool.

Anyone got any ideas or experience similar temps using MCHTemp?

My NB is on water now, but on air using MCHTemp I don't think mine went above 55c. I took the blue plates of the heatsinks for better air circulation around them. I would also get some kind of fan blowing at or close to it.

cheers mate how are you ?

i put my multimer inside MCH and loaded reports 46C at 1,5 i have 2 fans nicely blowing air over it and mem

Heh Sergio, doing real good, thanks.

I think maybe the MCHtemp program is off, I mean 90C+, thats way off the spectrum. Im gonna take off the heatsink and put some better thermal compound and see if that helps, if not Ill add some fans.

i would use a digital multimeter mate i dont trust that program as there's no real sensor on the MCH

Even tough its reading what is been disipated but nice either way

Check with a DMM

Damn, turns out the overclock I thought was stable wasn't. It froze while playing games a few times so I fired up prime blend and it froze within 2 minutes (requiring me to restart and turn off the PSU switch or it goes into infinite boot loop), which is weird because I ran blend for 60+ minutes before and I assumed it was, for the most part, stable; but I guess it's just a random amount of time before something would give.

I lowered Vcore in the bios to 1.30625 with LLC, and CPU-z shows 1.280v (under load) and still got the freezing so I bumped clock skews up to 150/200 (CPU/MCH) and got it to stop freezing (I think) but it only gets to about 30 seconds of LinX before BSODing with error code 124. I recall this same BSOD before but it didn't happen nearly as often. Now I did some searching and found that it has something to do with the VTT being too high or low but that was with i7 systems. Does the same thing apply to C2Q/C2D processors? Other sources say it's a generic hardware error and could be anything. Changing VTT from 1.24 - 1.4 doesn't seem to have any effect on correcting the problem though. Perhaps I am missing something? The last thing I want to do is raise the Vcore, for I am absolutely certain, for the extremely low stock VID of the chip, that it has nothing to do with it, as I have not gotten a BSOD 101, which relates to Vcore.

Any of you out there with low VID chips on this board mind helping me out? Is it possible that maybe lower VID chips might need completely different settings versus what is normally used? I mean in terms of VTT, MCH, PLL, references, etc :shrug:

@Dark-Energy
are you using setting from an older higher vid chip?
if so thats the problem.you need to find what the new chip needs in terms
of vtt.mch ref,cpu ref to make it stable.

sup mate i told you i will but you never got in msn

Well no, I'm not using the same settings from my E8400 (higher VID) but the settings are rather similar in terms of VTT and CPU ref. MCH too, but the MCH ref was much lower on my dual, on this quad I had to bump it one notch to stop prime from erroring

I know sorry :( I had it downloaded but I reformatted and upgraded to Windows 7....my instability hasn't changed though so that's a good thing...I can rule it out being the OS or HD

With a little help from andressergio and TeamViewer I got up to 4250Mhz. Voltages are kinda high but I am in the process of lowering everything without touching Vcore yet. Disappointed in the CPU voltage for a low VID chip and good board but it looks like the cooling can handle it for now(temps are the least of my worries thankfully). Got rid of the infamous freezing by raising clock skews (again) and for the first time I got Prime to error finally which was a huge relief; upped one notch on Vcore and passed 8K.

Finally at a stable OC but got a long way to go, but this is a good start.

Next step? The brutal time consuming tweaking.:brick:

next step - up the FSB! I managed 506x9 stability on my extreme board on the 8.5 multi but NB began to crap out on anything above that on my extreme, memory volts are very high, I'm guessing your ram is rated up to that? Must run hot!

My USB3P has left customs so my board's arrival is imminent- at last!

Yeah the ram is rated for 2.2-2.3 but I needed 2.3 for complete stability

Doesn't run hot though

This is what the ram looks like, big heatspreaders FTW :D

There's a DRR3 version too.

glad to help mate :up: and happy to see you are happy, dont worry for the volts there's time to bring them down, i tested like that so we can have a good start point and we did :D

Cheers :up:

nooo In-Fluence i took remote of his pc and helped him to get stable, we just started yesterday he wasnt stable at all, so patiently we started to tweak and so far so good we did it :up:

For what it's worth, my Kingstong HyperX DDR2-1150 (2x1GB) kit has 2.30-2.35 on the sticker (see my sig). They would not even boot at 500FSB with 2.4B multi for 1200 MHz RAM until I lowered volts to arouns 2.20-2.24 and remained stable. Maybe worth a try...more volts not always the answer, sometimes lower volts is better!

Sorry mate, I completely missed that part of the post!

The only reason I mentioned the RAM voltage was because the EP45 range (from my experience) seems to overvolt the ram by about 0.1-0.2 volts, and like Bluestang says, can cause instability. Now I've looked back properly, I completely agree - a good starting point with a little headroom for some higher clocks. Good luck with it ;D

yes its true mate but darkenergy was freezin in win over and over and randomly crashing, so i went for a sure setup wich i squeezed form my templates :) now we will lower volts

thanks for your input :up:

Update. I did some tweaking cause I ran into a few bumps in the road, got error in Prime 8x8 on the same core that failed before so I bumped CPU ref one notch in bios and it fixed the problem but then I ran into the blue screens 124 Error and some freezing requiring a restart and that was 2.2 Vdimm and 1.42 MCH so I bumped mem back to 2.3v fixed blue screen but then got some freezing issues so I played around with clock skews and fixed it again(I think, hopefully), but I bumped MCH to 1.44 as well...so really the only thing I did was change MCH down one notch and bump CPU ref one notch up from where I originally was. Will do some more tweaking today..... I was up pretty late last night.

Don't think MCH needs a fan though, I put my finger on the heatpipe close to the heatsink after a long period of testing and it was pretty warm, and a bit uncomfortable on the back of my finger. So I guess it is maybe 60C-65C? If it is unstable due to heat what will happen?

Did some Vantage testing too. Results came back at 17200 CPU score and 19400 GPU score for an overall score of P18808. Everest memory test was good. Read was 9200, broke 10k with write and copy, and the latencies are decent (55 ns)



edit: ok I am pretty sure it is stable now....

My USB3P and G.Skill Eco's have finally arrived! Spent last night backing up ready for a fresh install and some O/C sessions so watch this space over the weekend. I'll finally be lapping my CPU too just to get the most out of my last 775 setup :)

Dark Energy, nice going - I would run Prime small ffts through to around 16k, the CPU can crap out on 10-12k tests if vcore is a little too low. Just out of curiosity, what is everyone's weakest core?

grats In-Fluence :up: core 4 an all my quads meaning "I NEED FOOD" :ROTF:

Yup same here, core 2 always seems the next one to go - I wonder if it's something to do with power distribution over each die.

Anyway - I'm gonna shut down, lap CPU, then put new mobo in and tweak the night away - wish me luck!

I think mine is the same, core 4 then 2 most of the time.

Good luck!

My E8400 on dice did this:
valid 5292.3 http://valid.canardpc.com/show_oc.php?id=1225256
valid 5501.85 http://valid.canardpc.com/show_oc.php?id=1225245
valid 5509.3 http://valid.canardpc.com/show_oc.php?id=1225287

I know the cpu can do better but memory was the limiting factor:(

Hope u like my work

Cheers,
