Gigabyte EX58-UD5/Extreme Discussion Thread

[DavyBoy]

Is the mod for the ud5 to get higher PCIe clocks difficult to do, or can anyone do it??

[sunn]

No way...

I never knew about this novatech website before, if I had known they had Biostar Tpower mobos for that price I would have grabbed one of those instead of another UD5...

That is a great price for that mobos, as they are supposed to be quite good from what I have heard...

Might have to sell off one of my UD5's and get myself one...

What kinda problems are you having with your rig sunn??

Inconsistently and lock ups when not under load

Also looking at the Bloodrage....

[DavyBoy]

There seem to be quite a lot of people having problems with the UD5..

About my problem with only 4GB of RAM being recognized, I found a thread on Corsair support forums where two other people are experiencing the exact same problem as me, but they are using the Asus P6T Deluxe V2, and the Asus RIIE...

It is even the same slots on our mobos that are non functional, and they both switched out their CPU's and that cleared the problems for them, so I am now fairly confident that it is my processor that is bricked...

I was going to wait until I bought my fiancees i920, but I am just going to return in on Tuesday so that I can get a replacement one sent out to me...

I will keep you guys posted on here as to how I get on with the RMA process...

[feeza]

I've seen 3 1366 based motherboards so far, all exhibiting the same symptom of not recognizing more than 4GB. All 3 had bent pins in the processor socket. Oddly, all 3 had bent/crushed pins in the same corner position (2 different owners). At least 1 of those did not come from the factory that way, for sure. Doubtful the other did either. The reigning theory is that if the processor is inserted by angling it in instead of dropping it straight down, that may be the result. It's just a guess. No one wants to blow up a motherboard to test the theory.
To see the crushed pins, you will need to look very carefully at the socket preferably with a magnifying glass. Even a plain close look may miss it. Those buggers are tiny. Some have had success straightening them themselves, others made it worse.

[DavyBoy]

Bah,, I don't know how many times I have heard this now!!!

I always insert the CPU into the socket properly, I hold it with my thumb and finger so that they line up with the cutouts in the CPU socket, and gently lower it into place...

Again, I have checked my sockets on both boards hundreds of times to check for bent pins, and there are none present..

Also, if it was bent pins on the mobo, then why did the board I RMA'd work perfectly for the technician, and it recognized the full 6GB of RAM, and they even tested it with 12GB and it was fine??

I know that bent pins or bad contact with the processor can cause this problem, but I am 99.9% positive that this isn't the case for me...

This is what I think is wrong with mine...

The last part of that guys post is what I think is wrong with my processor...

[Jonny Manc]

I actually bent some pins (well I actually 'raised' or pulled them) on my motherboard when I did a resit and man...its soooooo obvious when its done :O.
Anyway, I was able to position them so that the CPU would push em back down and so far (a month later) all is good (though I touch wood lots, and cross everything).

I still agree Blunt, gotta be a mem controller problem and not a UD5 problem.
In the 15 or so motherboards I have owned through time, this is probably the best board of the lot but I guess its down to what you want it for!?

[DavyBoy]

Actually my first UD5 came with 1 bent pin in the CPU socket, and as soon as I removed the protective cover from the socket to install my CPU the first thing I saw was the bent pin...

I mean, when you have 1366 pins that are all in line with each other, if one of them is bent out of place, your eyes get immediately drawn to it!!

I know 100% it isn't bent pins in my socket, but when you come on these forums and people say "have you checked for bent pins?" it makes me think, well maybe there is some pins that are out of line, so I go and remove my cooler, and processor and then spend 10 minutes staring at the socket from all different angles looking for any bent or out of line pins!!!

Also people saying that the processor isn't seated properly makes me try and reseat it again, even though I have done this a billion times already!!

I really wish that it was something as simple as a bent pin, or my processor not being seated properly, but with everything I have done thus far with this system, I know it is neither of these two things..

Because my system used to see all 6GB, and I didn't do anything at all to it to make it only see 4GB, I just powered it up one day to find it only saw 6GB, I wasn't tinkering with BIOS settings or nothing...

I have to agree with you Johnny, that the UD5 is an excellent mobo, I love mine to bits, I just need to get this problem sorted out so that I can get the most out of my new rig...

I just hope that the replacement CPU I get will be a good overclocker!!!

i love ud5....


i am stable with:

4ghz cpu at 1.232v under load
1600mhz cl8 ram with 1.63v
3200mhz uncore with 1.28v-qpi

250cicle of linx with 95% of rm used during the test.


impossible with a p6t v2 i have tryed....

Those voltages are really good man..

Although my rig doesn't see all installed memory, I am stable @ 4GHz with 1.264v under load (this is just CPU-z though, I don't know where to take the readings with a multimeter) RAM @ 1528MHz with 1.64v (I haven't really tried lowering VDimm tbh) and 1.355v QPI, I have tried for lower Vcore and QPI, but anything lower than this causes BSOD's after a couple of passes of linX..

Is that a typo in your post?

Surely you don't let LinX run for 250 passes?!?!

20 passes is plenty imo.. I like to check my overclocks by running 20 passes of LinX using all available RAM, then leave Prime95 Blend Test running overnight, and then I let 3d Mark Vantage run around 10 loops, if it is stable after that, then I am happy...

with i7 plattform, more depends by cpu.....

bad cpu= bad voltage's
good cpu= good voltage's

i have tryed more i7 920 with more difference one by one.... more than older core2duo

im sure....250 linx passes

[DavyBoy]

250 passes is overkill imo, I would imagine doing 250 runs of LinX to check for stability would probably do the processor more harm than good...

It must take ages for it to complete 250 passes??

My rig takes 37 minutes to do 20 passes using 3000MB of RAM.. I'm sure I read somewhere online that Intel themselves recommend 20 passes of Linpack at the very most to check for stability, and 5 passes minimum...

To each their own I suppose, I certainly wouldn't want to do anymore than 20 passes..

Also, I know that each processor is different, and that some require less voltage for higher overclocks than others...

Though, the voltages that my processor requires aren't half as bad as some others I have seen online.. there is a guy from another forum with a D0 that he needs to give 1.375v for 4GHz... that is a lot of voltage for a D0.. I haven't seen anyone else online that needs this much Vcore.. he said that his processor needs that much voltage to be stable..

[ztop]

easy tune works on win 7 64 bit? wich version i have to use with this O.S?

[famich]

hello, Andrea, same here :: Linx Prime stable @2,32 VID

LINX-I think 75 passes are mor ethan enough , a lot of people do just 20,25 passes. Cheers

[ReverendMaynard]

250 linx passes = mental.

[barretp]

Does anyone mind PMing me the modded bios and instructions for the hard mod? thanks, I PMed Hicookie already, but no reply in 5 days

Also, what's the best way to upgrade bios in Win 7 64? Thanks guys

[123456iambelial]

I just bought the UD5 on newegg, I should have in 3 days. Right now, I am still confuse how to flash the UD5 BIOS using a USB flash drive.
Can someone enlighten me. pls???
Also, which BIOS is the best right now?

Thanks

Ok fellows, Im jumping of the gigabyte train Yesterday i sold my board and cpu, Mostly I were tired of my cpu, so i decided to sell that, and get me a D0, but i got a good offer of someone who wanted both my board and cpu, so i got rid of it

short story of the board, I had 2 gigabyte boards, both were actually very solid boards, the other where P35T board, and i personally think that these boards are as i said good stable solid boards, but then there is no more?
never had any problem, and if i did, mostly it comes down to some bios fault or something like that, that was later fixed.. but i dont find the board amusing enough for me, i can enter the bios in my sleep, and still push the right buttons, or adjust the voltages now i know this one, looking for something new, so i got myself a UT X58 board, allways wanted a DFI board, but somehow i never did..
though i like the BIOS and board support on this gigabyte, it has been improved alot! better than most others i must say.

OFC I will still read this thread and contribute if there's anything!

cheers!

Try running HyperPI 32M 16 threads

Almost want to bet it'll fail it

No offense, but Linx isn't the be-all and end-all test for i7

EDIT: For all you guys saying that you're stable just cause you can run Linx - go run HyperPI 32M 16 threads and I'm betting 60-70% of you will fail, Lynx is good for initial assesment, only when HyperPI 32M 16t completes without any error you can say your system is stable imo. And it takes shorter than 250 passes Lynx or 10 passes for that matter

CAN YOU LINK ME THE DOWNLOAD?

program homepage

direct link to the program in question: HyperPI 0.99b

HyperPI OC stability test settings:
pi digits to be calculated: 32M
processors (threads): 16

it takes around 35 minutes to complete on my pc

noone can say their oc is 100% stable if that test fails, it can only be it's very stable but not 100%

I had Lynx run 20 passes 11GB with no errors time after time, but hyperpi failed in just 10 minutes of the test... I had to play a LOT with my bios settings but now I can finally say in peace that my rig is stable and HyperPI completes 16 threads 32MB with no errors.

It is simple mate, just download whichever BIOS you want to use, and extract the BIOS from the downloaded file, then all you do is copy the file ex58ud5.f7 for instance (this is F7 BIOS obviously!) onto your USB pen, and restart your computer, then on the POST screen you can either press "End" key to enter the Q Flash utility, or you can press Del to enter the BIOS, then press F8 for Q Flash utility, and you need to select the file from the USB pen drive and follow onscreen instructions...

There really is nothing to it tbh... Whatever you do though, don't use the Windows based Flash Utility @BIOS.. I have used this method in the past, but I have been advised by loads of people that it isn't a good idea to flash with this software, and you are much better using QFlash instead...

Hope this helps you out...

[DavyBoy]

Oh, I forgot to say in my last post, but I have managed to tighten up my RAM timings a good bit, and still have a stable system..

I now have my RAM at 8-7-7-21-1T running at 1528MHz and a 4GHz o/c...

20 passes of LinX using max available RAM..



5 hours of Prime95 Blend Test..



Although CPU-Z says I have 6GB of RAM, this isn't the case, It is still only using 4GB out of 6GB which is really frustrating..

Also, I don't understand why my system won't run 200 x 20 with RAM at 1600MHz, when I can have it at 191 x 21 and RAM @ 1528MHz with those timings... I find this really strange.. I hope that my replacement CPU and the one I get for my fiancees rig will be better overclockers than this current one... tbh though, if this system would see all 6GB of RAM I would be quite happy with the results I've gotten here..

[Aberration]

How is CPUz reporting 6GB? Is the BIOS showing 6GB?

Sounds like an OS issue to me, like you are running 32bit or you have the ram limited with a boot up switch.
