If you're pc is stable don't bother, the sound your hearing is normal you probably have your fans off, turn all of them on and you won't hear the buzz anymore. :up:

all my fans are on i have an antec 1200 and its whisper quiet got new psu on the way anyway i blagged a new modular Enermax Revolution 85+ 1250w.

the buzzing on my board goes away nearly if i disable llc. not bothered about it now guys just want to know if it will be safe?

I currently am using a EK NB/SB 5 chipset block on my northbridge. Helps temps somewhat (I still get 40°C+). :shakes:

so how did you keep the hs on the mofsets on when taking off the NB off

does the heatpipe come off

Finally got everything and now have a bad stick of ram, got it running on 1 for now, haven't tried to OC yet but so far I'm really pleased. Haven't even messed with ram voltages but I don't think that will help my faulty stick, board won't do :banana::banana::banana::banana: with that stick installed.

Yes the heatpipe comes off very easily. All you have to do is gently twist it as you're dismounting the northbridge heatsink. It bends easily, so be somewhat gentle. ;)

alright thanks

should get it like wed-thursday

Sorry to question about this, but the screen from ORTHOS is really 8.5x500? cause ORTHOS have one problem about the multi, it always set 9.5, so my guess is that you were running 473 FSB, and the voltages doesn`t match with 8.5x500...

I`m looking for stability at 500 FSB multi 8.5 and my voltages are very different from yours...

Should I try to OC this with just one stick of ram? Also my board came with F6 bios.
Thanks

I hate you people :D

clo007,dude i feel your pain.you've probally had by far the worst luck with this board.and i can empathize with on this issue(i had sort of the same luck with my MIIF).i really wish you could have a fully functioning board so you could have the same fun and successes as most user are having.i gave up on the MIIF because of my experience with it and even though i have a new fully functioning one now,i wont use it ,or keep it. mainly because,"frankly" i already have a far superior board in the UD3P.so i guess what im getting at is dont give up on this board just yet,it is worth trying to get one that works.i've been keeping track of your problems for the most part,but is there any way you can do another RMA?if not maybe you can find a used or open box for cheap.i mean it is simply worth trying to get one that works.they are that good.any ways,sorry to hear its still a no go for your board.

I returned the rev 1.1 for a refund and I am stuck with this rev 1.0. I may pull the trigger first on the UD3P. I just wish Gigabyte tech support was more helpful. Here is the chat log with them:

Question - 710351
From : Chris
Sent : 1/27/2009 08:46
Question : I have 2 of the same motherboard, a rev 1.0 and a rev 1.1 with the exact same issue. NO matter what I do, or what kind of ram or size of the modules, I can only run 1 stick.
If I try to install both sticks, my computer just power cycles, never getting to the bios screen. As soon as I pull a stick out and run 1 stick, it boots up perfectly. With one stick i can even OC my Q9550 to 471x8.5 on stock voltage.
I have 5 different sets of ram I have tried:
GSkill Pi 2x2gig ddr2-8800 5-5-5-15 1.8-1.9v
GSkill Black Pi 2x2gig ddr2-6400 4-4-4-12 1.8-1.9v
GSkill 2x1gig ddr2-6400 2BHZs 4-4-4-12 2.1v
Crucial Ballistixs 2x1gig ddr2-6400 double sided modules 4-4-4-12
Crucial Ballistixs 2x1gig ddr2-6400 single sided modules 4-4-4-12 2.2v

All 5 sets pas memtest. All 5 sets do the same thing. 1 stick in it runs fine. both sticks in, it power cycles.
I also have found out other people are having the same issues. You can visit http://www.xtremesystems.org/forums/...205132&page=61 and www.tweaktown.com to see others with the same issues.

Answer : Do not perform any overclocking and leave all setting at default, are there any issue operating with more than one module at default setting?
We are unable to guarantee any results off from overclocking


From : Chris
Sent : 1/31/2009 23:10
Question : At default clocks it does not run on two modules. I thought it could be my power supply but it is not. I ahve been reading on the xtremesystem forums and tweaktown forums that others are having the exact same issue. I have a rev 1.0 and 1.1 boards with the exact same issue.

Answer : You had also tried lowering the spec of the memory as well?
Try testing with value ram instead of high performance memory also


Question - 712506
From : Chris
Sent : 2/1/2009 06:18
Question : I have lowered my GSkill 8800s to 800mhz speeds and nothing worked. I switched out to my 800mhz ram and it doesnt work.
You are now suggesting I go buy value ram to try and see if it will run on a motherboard made to handles DDR1333?

Answer - 712506
Answer : The chipset can support up to 1333fsb, whether if your memory is fully stable at that particular spec we cannot determine. If you feel the issue is within the board you may send in for us to further examine through the below website


Question - 713893
From : Chris
Sent : 2/4/2009 09:49
Question : If I mail my board to you, are you going to try it with some ram that I have? Or are you going to use some value ram?
I want to know this because I want to see if you can duplicate the issues I am having with my high performance ram and see if there is a solution you can figure out. Since I don't plan to use some value ram, I want to know before i waste my time and money to ship the board to you, that ya'll will look into this ram issue with some ram that is comparable to the one's I own.

Answer - 713893
Answer : We will test with the memory which we have on our lab, we do not have all memory on the market to test with. Since we do not have your memory we are unable to verified your memory


From : Chris
Sent : 2/10/2009 10:22
Question : Are you looking into this issue, as many people are having the same issue as me? Also, any idea of a updated bios or possible beta bios I could try out?

Answer - 716872
Answer : This is not an known issue, since we do not have your memory we cannot determine the stability of your memory which you are using. Do try testing at an lower frequency first to see if it'll improve on stability


Question - 717434
From : Chris
Sent : 2/11/2009 08:24
Question : I have tried running it at 667mhz and it still will not run with 2 sticks of ram. I am capable of getting two sticks to run in single channel mode by using memory slots 1 and 2.

Answer : If you feel that the issue is the board you may send in for further examination. Refer to the below link to submit your rma request
http://rma.gigabyte-usa.com

i just read it from the top down to the bottom and thought to myself, "what the #$#@" are these support guys braindead.then when i got to the bottom i see the statement to start at the bottom,makes more sense now. well here is a good priced UD3P.

Running G.Skill F2-8500CL5D 2x2gb. Put them in yesterday and doing fine at 1130mhz 5:6devider 471x8.5. Would be glad to post a Palate of my settings for you if someone can tell me how lol. Also ran 2x2gb of mushkin pc28000's no issues other than the ram wouldn't oc.


EDIT: Sorry man i didnt see the ud3r, thought you were on the ud3p.

lol, ok updated chat log to read top to bottom.

I am pissed that they say it is not a known issue but everyday i go to tweaktown there is a new thread about someones UD3P or UD3R not running in dual channel, boot cycling, etc!!!

Thanks for the the link. I was actually on newegg about to buy the UD3P. Has a rebate to make a bit cheaper then the ewiz one. I may get another PSU too, probably the 620HX.


OC nub, thanks but I am looking for people with the UD3R boards.

Sorry if I missed it...have you tried several BIOS versions and another power supply?

Tried f4, f5, f6 all with same results. I have a rev1.0 now and returned the rev 1.1 after it had the same issues. I don't have another PSU. I have talked to alot of people and they say my PSU should be fine. It is over 2 yrs old now, but I can still overclock the hell out of this mobo, proc, and ram(well one stick). I don't see how adding one more stick would make the PSU fail. I am hesitating to buy another PSu just b/c that's another $150 out of pocket if it is not the issue. I am thinking of buying a UD3P this time, and see what happens. IF it fails again, then it will have to be the PSu. At least if I get the UD3P and it doesn't work right, I can return it for a refund again.

513x8 ddr1026 pl9 8GB of ram,4hrs prime 95 blend stable.had to raise some voltages(cpu vcore-1.375 and vtt-1.36 and mch-1.40)to get it stable.
http://i40.tinypic.com/2col7om.jpg
the everest scores are a little low.wondering has any one tried messing with the pull-ins and ups?i want to give it a try but not sure on how to go about it.is there any thing i should know or should i just start advancing them one by one?could use some advice.thanks.

I play a lot to use all my ram kit install in this board total 8 GIG differnce spec as my Sig . found some
weird issue when I reduce Mch Dram Ref to lowest I got more stable.:confused: and I try MCH dram Ref set at default (0.9) It's become very unstable for me when I try around 540. Before this result I try a lot to get
540 -545 -550 with all that I can try no hope to success. I 'm not sure how far my RAM can go. Have to test it a lot....next I 'll play with Ch A and Ch B Reference Volt........May be some one can try out this weird stuff.
Note: I back to F4 Bios just only feel It can success easier more than other.

very nice BuGjAE.that is impressive for 8gigs. also thanks for the info on the dram/ref-voltage,im going to mess with this and other things in the bios and see if there are way to gain more stability and maybe squeeze out some more performance with the memory scores.i'll post back my findings.again great job there on that OC

@BuGjAE

Nice everest score :up:

I suppose you need that high MCH core volt, but man that´s high, what´s your temp on that MCH?

I have just below 50C with original heatsink/heatpipe (TIM replaced) at 1,34 with my Q9650@500 4,0GHz and 4x2 ram@1000 555 15.

I think vMCH 1.60 is not high temp with this Board I see only 44 C in ET6 even when full load orthos (may be cause a 2OZ feature???I think),I know it's quiet high but I don't know exeactly what vMCH
should hold 8 GIG PL9 :D stable ,I 'll down it later.
But I'm confident about MCH/DRAM Reference go lowest It's help me a lot.

I have 4 sets of 2x1 DDR2 and none of them work in dual channel.
