Gigabyte EX58-UD5/Extreme Discussion Thread

[bfghornet]

It's not a matter of should mate, it could be a matter of necessity depending on what kind of clocks you want to hit. Standard is much, much more forgiving from what I've found and although Turbo gives you a small boost in Everest cache and bandwidth, it's small enough to overpower with sheer clock power.

Thanks for this information Reverend. Ive been wondering about that setting since I got this board and never really saw a post about it until now.

Does anyone have SLI running on the ud5 on bios f5g under vista x64? I can get SLI working under Xp x64 and windows 7 x64 just not vista.

I've tried a lot of clean vista installs... I'm at the point where I have a vista x64 install with just the chipset drivers and the nvidia and a game or 2 but I can't get SLI working the games run at single card speed.

Tonight I benched i7-920 on Extreme with dry ice cooling, and I found some sort of MoBo cold bug:
system can't boot if Vcore > 1.53875 (BIOS). It goes to infinite power on/power off loop with following error codes: 11, 22, 55. Tried F4m instead of F5e and nothing changed.
This Vcore limit is low for my chip in 2D benches and cold water looks better then dry ice for it. DI clocks are 4500 Mhz for 3DMark 05 and 4450 Mhz for 3DMark 06, same as cold water.
Also processor thermal diodes can't show temps lover then -10*C. Temps are -59*C by thermometer, -10*C by RealTemp 2.90b, -60*C by BIOS monitor.
Is anybody here benched i7-920/EX58-Extreme on lover temps, on cascade or LN2? Do you have same issues?

I made a thread, but really haven't gotten any advice yet. I figured I would post it in here:

So I managed to get my setup to do 215x21 stable enough to run superpi, wprime and some other stuff no problem. I tried to go to 216 and it just wasn't having it. I think I set the vcore in BIOS to 1.64 to get the 215x21 OC to run.

So I put the setup on a vapochill LS and couldn't even get it to load into windows at 215x21 anymore. I upped the vcore as high as 1.68 volts but still nothing. Now I can't even clock it to 4 GHz stable, and it won't go past 159x21. I notice it doesn't even show the vcore in CPUZ, leaving that spot blank. And if RealTemp shows the VID at 1.0875 and now at 0.9750.

Should I give it a shot at RMAing the board, or the board and the CPU? What else could I try just to mess with this setup? I understand that messing with this kind of stuff I am bound to fry some hardware, and that is not a problem. Even if I can't RMA the stuff under warranty, I will just buy some more.

what do you guys think?

thanks for the help,

Mike

I have benched hours and hours with arena chess test (which is like running prime), 3dmark, pcmark, vantage, 32m spi, etc at 4.6ghz, 1.68vcore LLC enabled, 1.6vtt, 1.96DRAM, 1.96 cpu Pll. I had run ~10 prime 12+ hrs runs and many linpack when I first got the cpu, and after all the abuse at high volts, all my stable OC's require exact same vcore, qpi/vtt, etc. I would be surprised if one benching session at those volts did any damage, unless you have a defective part to begin with...or certainly one less viable then mine.

I had one situation, prior to doing any benching where all of sudden I was limited to low bclk...turned out to be a bad stick of ram, solved by putting in one stick of ram at a time.

Also I assume you have reflashed bios, if you are getting weird settings in cpuz. Also I assume you are stable at stock, ie not a corrupt OS.

But if you have narrowed it down to cpu/motherboard already, dont know what to tell you. Best way to investigate is with another cpu, without another cpu or mobo to try, would only be guessing. BTW...screenshot links dont work for me.

[Hondacity]

anybody tried this pencil mod?

[Leeghoofd]

My UD5 went bad, corrupted bios, S-ATA controller is messed up, ... Mobo got into an infinite reboot (my girlie called me after half an hour that the she couldn't get into windows, the pc shutdown,rebooted all the time)

End result : one dead mobo, one dead raptor and 2 Tb drives messed up... why can't Gigabyte implement just a no post, then user push the power button till it shuts down and then repost with fail safe values like the Asus mobo's... I already hated this failsafe feature on the P45T and this UD5 is the same...

i tried it and it didn't appear to do anything at all

@ Leeghoofd, damn dude, that really sucks about the bad hardware (had an ultra x3 1kw psu die yesterday after about 1/2 hr of use)
although the process you described, sounds similar to the way my board recovers from a bad oc
if it doesn't post while overclocking, usually tapping the reset button a couple of times makes it boot up with failsafe values

has anyone heard of any new bios's coming?
hoping that it was just the new year celebrations that slowed down the releases

hmm I am going to try to remove some of the RAM and see what happens. I have the computer running with the RAM multiplier set so my RAM is running at 1600MHz even at a 133 bclk on the processor and it works fine. So I'm not sure what is going on.

You are correct that I reflashed BIOS (from F1 to F3) to see if that corrects the problem. I also have a stable system at stock clocks, and the computer runs like a normal computer at stock clocks other than the fact I can't see normal vcores.

I do still have dielectric grease on the socket. I don't think it is causing any problems as the system initially clocked fine with the dielectric on the vapochill.

Ok im back at F4j... F5e didn't resmued from S3 with oc, while F4j has no problem at all.

Sounds like what happened to mine a few weeks back, been fine since.

Weirdest thing, just turned it on. Been fine for weeks, got half way through loading windows and it restarted. Went into a reboot loop, turned off and it came up with corrupted bios recovery. I flashed the bios back to F4J from F2 and it needed a cmos reset before it would start. Put the settings back in and its fine again. What would cause that?

I got my UD5 setup over the weekend. I haven't had time to fine tune things yet. It came with the F3 bios. I flashed to F5G and it seems to be doing better. It sounded like F5E was highly touted, but I can't find it anywhere. I've been priming for quite a few hours at 4GHZ. Here is a screen:

Don't use RealTemp 2.70, it fibs about Core i7 temps and shows them lower then they really are. Use 2.90 at least.

cardnut ... whats your cpu cooler??? air etc??

Quick question guys, someone over at ocforums stated that turbo mode on only overclocks one core with the extra multi. Is this true?
Cuz, I thought I seen multiple times stated here that the gigabytes properly run turbo mode on all cores and lock it at that speed???
Thanks for the clarification!

you have one...why not test it? Cores are either disabled, or they all have to run at the same multi. They aren't independent that way.

[GenTarkin]

Well, I did not know how to see if they were clocked differently, but now that you just told me they are all same speed or disabled????
That right?
So, i7 cores cant run at different multis at same time like the phenoms can?

correct. The only time you can adjust a multi on a single core with the i7 is if you disable the rest. Then you get the magic 22x multi

[hlonipha]

How could I test this ? I thought I read somewhere here that only one core would use the 21 multi out of the four.

[hlonipha]

I found this "

The latest revelation is Turbo Mode. According to IDF stalwart and all round Intel evangelist, Pat Gelsinger, Turbo Mode allows individual cores in its upcoming Core i7 desktop CPU to be entirely switched off.

That in turn allows additional power to be channelled to the remaining cores. The idea is to boost performance in applications that do not make use of all four of Core i7's processor cores.

Intel says that for single threaded applications, the technique allows the speed of a single core to be boosted by two "bins". In layman's terms, a bin translates into around 200-300MHz.

[Khalmyr]

man, it's like this

you have your 920 at 20x which is it's default.

if you have turbo on, all cores run at 21x, all the time instead of 20x.

when you're running a single thread app like superpi, and the other cores aren't doing anything else, they switch off and the single core you're using goes up to 22x.

so the 920 is actually 2.8Ghz by default instead of 2.66, cause my mobo came with Turbo on, and on first boot all my cores were running at 2.8Ghz

[ReverendMaynard]

I found this "

Intel has very little power over what motherboard manufacturers do with the available technology. Gigabyte happened to choose to bypass TDP regulation and give us a permanent 21x mutli that is functional during load on ALL cores. Let's leave it at that, because this thread has covered this topic about 50 pages ago.

I am just about finished getting parts for my i7build.

Intel i7 920
Scythe Mugen 2
Gigabyte EX58-UD5
Corsair 850TX

I just need ram but my budget has just about run dry

I really don't want to skimp on ram and I would like a 3x2GB kit

How doe this ram play with the UD5? G.SKILL 6GB F3-12800CL9T-6GBNQ.
Here: http://www.newegg.com/Product/Produc...82E16820231225

Some other ram for a similar price?

For the price, it's kick ass and yeah they'll run perfectly in any X58 motherboard.

[road-runner]

So which bios is performing the best for the X58 UD5 right now?
