Oh crap I just bought a 1200w Toughpower to use with this board. I'll let you know how it turns out. If I have problems, the PSU stays, the board goes!

Make sure you stress the system before you turn it off, then turn it on as soon as it turns off.
I'm allready starting to think about a replace with another brand, any one knows a site that ships world wide, I'm thinking DFI or Asus.
I had a bench session tonight with the TT1200w with i7 920 at 1.55v under cascade & hd4890 CF and didn't have any problems with multiple restarts. The psu handled it well.
afaik there are a couple of different revisions of the psu range. Mine is a W0133
what the highest bclk anyone has gotten out of this biotch?
I havent tested long under the cold with the board. I can boot & bench at 222x21 with a C0 920 under cascade. Haven't tried higher yet.
My max BCLK is 221.9 Mhz. There are rumors that PCI-Express clock is bottleneck for BCLK and raising it over 110 Mhz will solve BCLK wall, but I can't stabilize even 103 Mhz PCI-E on EX58-Extreme with 8600 GT (or old PCI S3 Treo64, same sh*t :)), so I can't proove or disproove it.
DDR Phas LED, when my mobo fails to boot these 2 LEDs ( a green and a yellow LED ) turns on, what causes these LEDs to turn on or off?
I'm reading some old posts on this thread and found out that lowdog has the same problem as I am!
Hmm.........now is this a gigabyte issue or a Thermaltake issue....?
Whatever. Sell it, get a new board....live on.
No newes that some motherboard dont like some psu;)
Finally got this :banana::banana::banana::banana::banana: to work 200/2000 :rocker:

I ordered another evga gtx 295 red today but not sure if my UD5 board will allow for quad SLI of the (2 gtx 295). can anyone confirm that the cards will fit.
thanks
Has anybody get more than 222 Bclk until now?
Is it someone here that have tried or heard something about this batch: 3847A764 ?
My Gigabyte mobo and 920 D0 is coming tomorrow:D
Exact same batch as I have, up to 210x21 no problems, but above that it starts screaming: "more volts, more volts":p:, since my gpu refuses to work with increased pci-e clocks I can't get past the 222 barrier, so can't tell you how much higher the chip would go. 1.33 vcore in bios (1.30 according to various apps in windows under load) gets the job done fine for 200x21 24/7 at 100% load on all cores with HT on.
210x21, didn't even increase volts above my 24/7 settings and could still run spi1m, dumped the memory timings though to remove a potential bottleneck as I'm using dirt cheap ram that requires some excessive tweaking to run stable above 1600.
UD5 F7d bios is out:
http://www.fileden.com/files/2008/7/...x58ud5.F7d.zip
its from 5-5-09 only 2 day's old. Maybe its fixing the issues you guy's have ?
Yep, it fixed Dualcoldboot for me, and random blank screens at reboots etc.. i also applied ALL settings at once for Cl7 and 4,2ghz, booted up fine.
BUT and i mean this is in ALL F7 Bioses, it requires More vcore to be stable.. and not just a notch, more like 0.3+. Dont like it, why does it become like that?

thank for your time
here you go, would be nice if you tried one f5 one f6 and f7d? :)
http://www.hardwarecanucks.com/forum...review-14.html
To be stable with bios F7D it takes 1.34v vs. 1.31v with F5G. could someone confirm if it is adjustment or real volts?

Just tried f7d. i7 c0. All power saving off. Big ftt and small ftt give pretty much the same reading +/- .002v LLC on.

Will try other bios later.
Sweet dude :) now we just need to see the diffrence between that and F5G :) to see as above thread, if its just adjustments or you really have to raise vcore.
thanks for the effort! :)
regards.
Be interesting to see what dmm reads on another bios. On GB P35, with one bios change they did adjust vcore values and confirmed such, but only changed couple notches.
I have not seen any vcore requirements change on Extreme bioses, I tested many (all on same day) a while ago, and just tested 3 bioses again, with same results.
EX58, 21x200, all settings exactly same, except different bioses, testing linpack 4096 mb memory.
vcore bios 1.425
F7C froze 2nd pass,
F5 rebooted before 1st pass
F4j rebooted 2nd pass
vcore bios 1.431
F7C reboot 6th pass
F5 reboot 7th pass
F4j reboot 4th pass
vcore bios 1.437
F7C, F5, F4j all pass 15 runs.
Infa and hlonipha, did you guys go back and recheck your older bios vcore requirements for stability to make sure you still get same, ie test both bioses on/near same day?
Here you go f5g. i7 c0. All power saving off. LLC on.

lol...it pretty much the same. I wont try other bios because I have the feeling it also the same since f5g to f7d is quite far. So use what best for you.
Here some HT off/on
bios vcore 1.4v
idle - the same - 1.371v
load - dmm
HT off - 1.364v
HT on - 1.360v
:toast2:
Interesting though, looks like mobo does a good job with voltages and sensors.
f7d is garbage....need pretty high vcore without gain.
use f6d. Normal vcore like f5g , S3 working , quick ram timing but still old AHCI rom.
Will try that too, but if any problems occur, F7d will be back :)
and thanks all for the DMM readouts :) allways appreciated!
Ok now i had it with this board!! To much :banana::banana::banana::banana: and problems all the time...
recently i got this USB error thing, it will boot up allright and stuff, but first when windows loads MBR, and logo shows up, USB shuts off and then to be initiated with windows drivers, as in any windows. then it sometimes even wont initiate it, and sometimes it does, but it still just stay there and do not load windows...
I tried to raise voltages concerning this, also turning integrated things OFF, sometimes it works turning etc the other SATA controller off, but then it works, and then i have to reboot somtime, then it is the same again, then i turn LAN 1 and 2 off, then it works, and then it dont, then activating SATA controller again, makes it work, and yes my enthernet is broken since a while back just like that it dont work, so i got a pci card, and then ofc it works, and the USB thing STILL dont work whatever i do, tried many bioses, and now this last time i turned azalia off, and now it worked again, WTF is this? I've had it... to much small things.. to much BIOSes to fix what should have been fixed months ago.
last time Gigabyte, next time NOT.
Hey,
Glad to see this thread. I found this link on TPU.
My config:
i7 920 D0 @ 4,2 Ghz stable BIOS F7D
Gigabyte X58 UD5
OCZ Platinum 1600 Mgz 7-7-7-20
Scythe mugen 2
XFX GTX 280 1GB
I'm now running @ 4,2 Ghz 1 hour OCCT stable with 1.2875 Vcore.
I've read some comments about F6D and F5G that they are better BIOS's for overclocking?!
I don't use AHCI or S3 so that won't be a problem for me.
Which BIOS is the best for overclocking?
F6D / F5G?
could you please upload the BIOS to rapidshare / mediafire or something?
Many thanks :clap::up:
They are all listed here http://forums.tweaktown.com/f69/giga...st-bios-28441/
Tred the F6D bios.. isn't good as the F7D.
Got OCCT error after 3 min. with F7D it took me 15 minutes for that.
can someone help me out with my xtreme mobo...
i have a 920 c0 and i cant even get 4.0 stable with ht on...i dont know if im doing something wrong or if its a crapy mobo/cpu
iv tried a lot of different voltages but nothing can get it stable right now im running 1.5vcore to eliminate the some variables but still no luck my temps are under control with my watercooling so i know thats not the problem
im running f7c bios with 6gb of corsair 1600 ram if someone can post their settings or maybe upload their oc profile so i can have something to work off of that would be awesome!
Mine is 940, but using 21 multi. First I would find max bclk with reasonable volts (not max bclk with benching volts) to see if limited, then try stress testing using 16 multi with bclk 191, with mem 8x, uncore 16-17x and see if bclk/mem/uncore issue. If that fails then drop mem to 6x and rule out memory issue.
If that passes, then try qpi 36, uncore 16-17x, mem 8x, multi 20 with turbo on so get 21 multi, bclk 191. loadline enabled, vcore (not sure where to start if you are already using 1.5, hope you dont need that much) but start at 1.45 then work way down if ok, qpi/vtt 1.45 (then do same work way down if stable), DRAM volts 1.64 or 1.66, then I also have qpi pLL, IOH, cpu PLL all set to 1 notch above normal. Buy you might want try cpu PLL a few notches above if yours is vcore hungry.
My guess is you would make your life a lot easier with trying lottery again with D0 (one of the places that sell D0 guaranteed like tank guys), judging by most I have seen easily getting 4.0 easily with low volts, then sell your C0. If you have already tried a lot of volts, you may just have a crappy cpu. Changing mobo's may buy you a few extra mhz, especially benching, but not going to fix a crappy cpu if that is the case.
yea i really want a d0 but no one wants a c0 anymore so i doubt ill ever sell it
Can someone here give my some advice on Blck, my Gigabyte UD4P dont want to go over 190.
I think it is becouse i just have played with vcore. Have tried 190x12 on 1,3v and nogo.
I have a D0, and it is fine on 180x21 on 1,22v.
Try with below settings:
Cpu Features:
Diable everything except the following: Turbo, Cpu Cores, Multithreading
QPI set it to x36
Uncore multi will depend on ram multi.
Performance enhance, Extreme can be a bit tricky to get it to work at high clocks, set it to Turbo for the time being, standard doesn't really help (unless you are really pushing the last bit out of the ram) , once you have a stable oc try to raise it back to extreme.
Ram timings, just put it to whatever your ram is rated for, I'd oc the cpu first, then if it's stable add ram clocks / tighten timings (ram speed is not really important for I7 in real world performance).
Loadline Calibration: Enabled
Vcore: this will vary widely from cpu to cpu, I'd start with 1.3, the system will most likely boot, unless you have a miracle chip it won't be stable with any load though, just raise as needed in small steps (up until around 1.4 temps should remain acceptable, above that you will need some serious cooling)
QPI / VTT: My chip loves 1.36, but again, your mileage will vary, start at 1.32 and give it some small bumps until stable.
IOH Core: 1.2
Ram voltage: will depend on the ram
CPU PLL: Leave it on auto, it does not really have a big effect
PCI-E V: Auto
QPI PLL: This helps a lot, just go straight for 1.3
ICH I/O: 1.7
ICH Core: 1.24
Why do you modify the ICH settings? That's the southbridge, does anyone else suggest this? I'd be curious for some second opinions regarding the QPI PLL setting as well, it's one setting I've not tested as I don't want to damage anything.
I was going to make a post asking about Loadline Calibration as I am looking for more data, but since this is the Gigabyte thread... has anyone already done some testing to determine how much of a lower vCore they get with LLC enabled? So far I've run with it disabled, but my CPU absolutely requires 1.42v with LLC disabled to remain fully stable at 4.2GHz.
I have two problems with my UD5 (Bios F6),
1. ET software doesn't show voltages anymore (have seen them on first usage)
2. After changing bclk in ET multi of 21 will not be used anymore :(
I'm coming from P6T with a Xeon W3520, any hints or tricks for getting me a good setting in the range of 4,2 - 4,4 Ghz ? 4,2 used under 1,3v on P6T with LLC enabled, just for comparison.
Thanks in advance guys ;)
I know, but I wanna raise the pcie clock over 103MHz!
Temporarily it's not possible!
I dont know how far you already go with it but I´m just right at this clock ; still learning the quirk of the D0. If anyone know a better setting pls post it.
Will try more later this weekend for useable 4.4+GHz HT on and 4.5+GHz HT off.
206x21 - 4.326 Ghz HT on

hi guys
I NEED HELP !!!!!!!!!!
I have just built a new rig
i7 920
Gigabyte EX58-UD5 (F6 BIOS)
6GB Corsair 1600Mhz
Quattro 1000W PSU
4870 512MB
I also have SAS controller with 10K sas drives which I set up to be in RAID-0 and installed Vista on it. Also put all latest MS updates and have latest drivers / BIOS for all devices.
So basically up to this point, everything works fine, Vista boots ... performs great.
Now ... I plug in any SATA HDD, it wont boot. When I try to plug in my NEW HDDs I also bought (2x640GB WD Green), it boots into Windows, lets me initialize them but I can't format them. It just says formatting but does nothing (this is same for Quick and Normal format). This happens on both the Intel ICH10R or Gigabyte (JMicron) controller. I tried all ports, all possible settings in BIOS, no diff. really dont know :(
I tried setting in BIOS both AHCI mode (and yes, I installed the correct Vista drivers) and Standard ... also tried Native IDE and NON-Native .... still same problem. Cant format the HDD.
any thoughts ? please help!!!! I am getting desperate! Any help is much appreciated.
#1 This is odd, ET6 has no problems on my motherboard. Make sure you are using the latest version from their site, NOT the one on the original included disc. (Mine's the 4/17/2009 Build)
#2 This occurs with most software that makes changes within windows from what I know. As everyone has said, make changes in the BIOS to work around this, it's much more stable this way anyway. :)
As someone had asked:
IOH is the X58 "northbridge" This is the I/O Hub, hence IOH
ICH is the X58 "southbridge" Standard ICH10, just like the ICH9, ICH8, etc before it.
Has anyone verified what the Gigabyte Performance Enhance setting changes now? I tested Turbo and Extreme, but all of the RAM timings/subtimings remained identical... since the IOH is not the MCH anymroe, what is this setting good for?
Sparda, I'm looking at your BIOS settings... why do you have EIST still enabled? This is speedstep, you want to turn that off for high overclocking. Uncore frequency depends heavily on each individual chip, regardless of batch# or anthing else. Chips in the same batch as mine can hit 4GHz Uncore fully stable, mine can't go much above 3.6GHz without going unstable, so I use the 18x setting. Since your memory has an XMP memory profile, you might want to enable that rather than manually setting the correct memory timings. :) I'm using VTT = 1.3v and IOH = 1.2v for my sig overclock, but I've not attempted to lower these settings further yet.
If the EIST is disable , the multi will drop from x21 to x20 after wake up the system from S3. Using S3 since I hate to see and wait at the bootscreen. I dont know much but it kinda bug. So it need to be enable in order to use S3 and turbo. It doesnt have negative effect though afaik.
You are right about the uncore. It can do 4Ghz stable but start flakey at 4.1Ghz My ram doesnt have xmp. It the normal ocz cl7 platinum. Still curious about the ioh and qpi/pll though because I dont need to touch them before.:confused:
That's what I'm assuming, but there are no tools that show the perf level setting anymore? Memset doesn't run on X58. I guess I should run some SuperPI tests and see if that shows any difference, but I was wanting to at least see or know exactly what it did on X58. :) It used to be a huge stability issue on Extreme for me with P35, but right now my X58 motherboard doesn't seem to care if I use Turbo/Extreme at all.
Sparda, according to the info you gave you have an option for Extreme Memory Profile (X.M.P), unless you didn't delete it when pasting in BIOS settings. This setting is only visible if your memory supports XMP. So if you can see it then you memory supports it.
I can't run Extreme at all, and between my Turbo and Standard scores in Everest shows on all tests that it increasing bandwidth and lowering latency.
When I get my Extreme back in next week, I'd be glad to benches and post up the results.
For now, I'm tearing it up with this eVGA X58 Sli :)
8b is out for the extreme , anyone tried it yet ?
I am using 8b Ex, but the one with new AHCI rom via noangel post on tweaktown (same thread as stasio posts), so far it boots faster through the detection process which is nice, just starting to test other things...
Okay, I've had time to play with it and have double-checked all three settings.
For my board the roundtrip latency remained unchanged at "59" regardless of Standard, Turbo, or Extreme. All of the timings shown in CPU Tweaker remain unchanged as well.
I did a quick SuperPi 1M run, Standard and Extreme settings was 9.653 and 9.633 seconds respectively. Whatever setting it changes, it has a very minor impact now as compared to previous chipsets. :shrug:
I am trying to get past this 222 blck wall. 223 does not boot. 222 is easy and to bench only requires 1.42 volts, atleast for superpi.
3dmark06 requires 1.5volts.
But I can't get past 222. I tried the PCI express thing, it doesn't work.
I added more voltage it doesn't work.
I can't even boot at 223.
It does look like the most recent bioses on extreme have little difference between turbo and standard, in fact none that I can tell yet. I tried everest as well. I remember on earlier EX bioses round trip latencies and other secondary timings were different between perf turbo and standard, as well as spi and everest.

second perf standard
http://img40.imageshack.us/img40/572...4200bios8b.jpg
And extreme is exact same as first 2, looks like on these later bioses, that perf. standard, turbo, and extreme are either the same or nearly same.
Using settings in my sig, ran everest on a clean boot:
Extreme
Read 18225 MB/s
Write 15908 MB/s
Copy 22860 MB/s
Latency 43.4 ns
Standard
Read 18140 MB/s
Write 15903 MB/s
Copy 23098 MB/s
Latency 43.8 ns
Ran the tests several times, numbers were generally pretty close. Only marginal difference was the Standard Copy number which was usually slightly higher than the Extreme number.
@sparda: thanks for the template, but my cpu doesn't really like it :)
@Kougar: I'm actually using the newest version of ET6 from their website, but since i've found myself a good settings it's not really important anymore
One last thing, i'm currently on Bios F6, will a newer version give me better results ? Which one should be best for my Xeon W3520 ?
A Problem occured to me while trying to encode a BD to x264. FFMpeg or Mencoder stop nearly immediately after starting to encode, but i'm am over 6 hours primestable with this setting... problem somewhere else ? Maybe forgot to install something ?!? Or what could it be. Using Server 2008 atm...and i like it, but that i can't encode sucks big time :)
I just checked on mine again, it does change round trip, but only by a tiny little bit, talking 1 -2 here. But the difference is so small it might as well just be a incorrectly displayed value in the Bios / cputweaker, that is with F6 on the ud5.
with 200 bclk, x8 ram multi, x16 uncore, x36 qpi, x20 cpu, turbo + ht on / rest off, cas 7, trcd 7, trp 7, tras 20, cmd 1 (all subs on auto) everest gave me the following:

hi to evreyone..
i relly need some help here..
this is my reg:
920 D0
EX58 EX with f7c bios
1st stage cooling (-62c' evap)
ocz 1600mhz 8-8-8
and ocz 700w!
and more..
the problem is that i can get more then 200 bclk stable!! no meter what i do in the volt..
i can boot with 235 bclk but the windows will no start..
can some one tell me if that is the best bios for me?
the cpu temp from bios with 229bclk 1.5v it -21c' soo that ist the problem...
can someone give me the best seting for the extreme board in 220bclk and with which bios?
thanks
i hope i will get some good records..
thanks and sorry for my eng.... :-)
Ye 1333, sorry but I've not had much luck beyond 201Bclk myself so I wouldn't know. You might have better luck posting in the subzero cooling subforum?
Some would suggest using newer beta BIOS's (the links are in this forum) but I wouldn't. I'm happy with F6 and personally can wait for official, non-buggy BIOS releases. It's up to you. ;)
It would not be the first time "Performance Enhance" setting does nothing. In this case it sounds like all it does is tighten up lax low level timings... from what I can tell all of my timings are pretty tight already so perhaps there wasn't anything for it to tighten? That theory should be easy enough to test by setting really lax memory settings, but I'm not going to worry about it at this point.
I'm on F4J....wonder if that makes a difference?
I have EX58-UD4 and I notice my PC wakes up automatically 5 mins after I put it to sleep. Is it a bug?
i had the same prob.
go to the device manager>network adapters
right click on the NIC and select properties
click on the power management tab and deselect "Allow this device to wake the computer"
anyone have luck upping pci-e speed? anything over 100 on mine cause no boots
On my Extreme i have same problem, it will do pcie 100-103, but 104 and above I get a blank display, and get same on many different bioses. I tried switching to an old 7600 nvidia card I had, same 103 pcie limit, guess I need to try an ati like reverend said, but dont have one unfortunately.
But looks like some second generation mobo's have better circuitry/layout with cleaner signals allowing higher bclk, etc, not to mention cpu's themselves ie, D0's with higher capability. 255 bclk on classified with 248 bclk benching stable is pretty impressive for both cpu and mobo. Wonder if GB will be releasing any new revisions soon.
actually I have a 2600 retard helmet edition (low clock gddr2) Might give that a shot
let us know if you do, be interesting to see if that helps.
just saw your sig, you have the classified?...have you tried the same cpu in both classified and GB extreme, I realize comparing a second gen mobo to first, but interested to see how much higher bclk can go in diff mobo, if cpu is controlled, ie same cpu.
Getting ready to install my i7 setup (on Tuesday):
EX58-UD5, 920 D0, 6gb GSkill DDR3-1600
Whats the best bios around at the mo, I aint looking for the highest clock, but between 3.6 and 4ghz on some low volts......
Cheers :D
Some people post their bios settings in a nice php code window. How do you get your bios settings listed so nice? Ye olde pen and paper and make a nice layout yourself? Or use some program to extract it from the bios?
Try using 1.6 PCIE Voltage and a high QPI/Vtt and IOH Voltage, both at or above 1.4 should be good, and then boot at 210-220 (whatever is the highest you can boot with is better, I use 220) . Set 100 PCIE Freq in the BIOS to 100 and then use SetFSB to change your PCIE Freq slowly testing your Blck as you go from 100-101+
I just done this tonight using 102.4 PCIE Freq, will be going further once I find some time. No fancy cooling used here, just water :D

Yep, from our crazy minds or ye old pen and paper into a blank template
Bus Frequency testing (QPI/BCLK)
I did some QPI/BCLK/bus frequency testing to see if i could break the 222Mhz "wall" I had in my previous tests. It was a bit of a tussle but in the end i managed to get some extra bus speed through few different settings outlined below. It seems as thought PCI Express frequency, uncore "sweetspot" volts and settings you boot at are the main driving factor from my initial testing in achieving higher/stable bus speeds or QPI or BCLK or whatever people call them. I was maxing out at 102.5MHz PCIe frequency in windows and while i also managed to find a sweet spot to let me OC a touch more (103 or so MHz) i was not able to make a run stick even though i did have a CAS6 run running at 228.3MHz bus only to crash on 16th loop...it looked like a 7m30s run :)...
Here are my findings so far. Disregard the SuperPi efficiency.......i was just testing frequencies.
I'd love to hear from Gigabyte X58 board owners about their experience and whether these settings help anyone reach higher clocks.
I'm in touch with Gigabyte guys about this so hopefully they can figure out what it is exactly, whether it's the PLL chip or signaling/traces issue or whatever. All i care about is 250+Mhz bus speed stable on any GFX card :D
Test Configuration:
- Gigabyte X58-UD5 F4n bios (old bios for initial testing)
- Intel Core i7 920 retail chip 3849A910 D0 stepping
- 6GB 2000MHz CAS8 DDR3 Corsair Dominators
- Nvidia 8400 PCIe Graphics Card + Xfire ATI 4890
- 1000W HX1000 Corsair PSU
- 1hp C-BuZz Single Stage (kayl evap) > on CPU
- 160GB IDE Hard Drive
- Windows XP Pro 32bit SP3
- Windows Vista Ultimate SP1
BIOS SETTINGS:
- CPU PLL Voltage: Auto or 1.80v - same effect
- CPU VCORE: 1.35-1.36 - same effect
- IOH/ICH 1.1V Voltage: Auto or 1.20v - same effect
- IOH Voltage: 1.42v (i havent tried auto...dont think it matters)
- ICH PCI-E Voltage: Auto or 1.5v - same effect
- QPI/VTT: 1.433v or 1.455v = this chip's sweet spot (any higher or lower and i was unable to push past 101MHz PCIe frequency in windows)
- VDIMM: tried between 1.66v - 1.94v same effect
- BUS SPEED: booting from 200 or 210 same effect, lower or higher i had problems going past 101MHz PCIe frequency in windows
for the record i could boot at 220 straight from bios to windows...sorry didnt try higher..will do next time- PCIe FREQ.: Auto or 101MHz - same effect....102 would occasionally boot but every now and then throw an F6 error iirc...anything higher and no boot at all. In windows i did not see 101Mhz PCIe freq. in SetFSB even though i was selecting it in bios so not sure it was actually sticking at all.

Thanks. Thanks solved my problem. :)
I wonder it is OS problem or drivers problem? I never had this problem with Vista x64 but facing this problem with Win 7 RC.
By the way another question on overclocking. Currently my C0 920 is stable at blck 170, 3.4Ghz with HT and Turbo on. All the voltages are in stock/normal and Vcore at 1.15V. When I try 175, I will get BSOD with LinX. Try upping the Vcore but still the same. Has my CPU hit the limit? I think 3.4Ghz at 1.15V is pretty good with load temp around 65C.
