Gigabyte EX58-UD5/Extreme Discussion Thread

[X.T.R.E.M.E_ICE]

will release new beta BIOS lafter , both for Extreme an UD5
improve some auto-tweak, memory oc, and warning page.

Thanks champ.

F4L and F4N have my multi locked up at 22 on my 940, whether or not I have turbo on.

I absolutely cannot get past 180 mhz bclck, even up to vcore of 1.525 ...other voltages I have taken up to (and a bit past) settings I have seen others have here and in the i7 overclock thread. I dont know if I havent already hurt this cpu, or if it is the bios, or why the reason is that I am locked in at 22x.

It feels like I cant get the qpi over ~3300 but without being able to change the multi its hard to tell. I need a x30 qpi setting. Running qpivtt up to 1.535 and qpipll up to 1.3 did not do anything to stabilize it (at 181 bclck).

So I am stuck at 4140 MHz...without HT, b/c even running that I cannot get it stable at up to 1.525 vcore

I think I found my 24/7 clock, lower than I wanted, but hey can't have everything :P Have to do the memory settings next.

180 x 22 Turbo ON (so x23 or 4140 mHz)
QPI x36
Uncore x13 (12 seems unstable)
Mem x6
Vcore 1.4875 (any lower BSOD during linx)
QPI/VTT 1.34 (see vdimm)
CPUpll 1.88
QPIpll 1.24
IOH Core 1.4
ICH I/O 1.58
ICH Core 1.22
Vdimm 1.8 (older ddr3 ram)

No screenies, but with the high vcore there is nothing new to spam the thread with Temps are at about 80C under load (linx) and 70-75C(prime), with vcore 1.456 load. LLC and turbo are on, HT is OFF. Cooling is a true black 120 (lapped) with a scythe ultra kaze 3000 zip tied to it.

At 1.525 vcore I still cannot turn HT on or go to 181 bclck (even turning turbo off), and Load temps are in the 90C range.

Note on raid: get a separate controller card. Intel/mobo raid is free, and you get what you pay for. I have had no good experiences using built in raid. Just my $.02

that's normal mate
you will never be able to select 23x multi in bios on 940

overclocking nehalem in particular is a LOT more complicated than just mimicing other users

i spend a good 4 serious testing/overclocking sessions before i could get my head around basic settings and OCing.....it takes time and patience to get it right and voltage tweaking is important but upping voltage does not mean you are going to gain stability....it actually needs to be the right mixture of volts for things to work smoothly

180 x 22 Turbo ON (so x23 or 4140 mHz)
QPI x36
Uncore x13 (12 seems unstable)
Mem x6
Vcore 1.4875 (any lower BSOD during linx)

IOH Core 1.4
ICH I/O 1.58
ICH Core 1.22
Vdimm 1.8 (older ddr3 ram)

i would suggest higher QPI/VTT >> somewhere 1.5 or 1.55 particularly if you are going to run vdimm at 1.8v or more

for high NB speeds you will have to jack up uncore and RAM volts even more

sounding like a voltage tweakin issue

start with what i suggested and do some more experiementing on your own
how are you setting RAM timings in bios....try auto and manual set...use latest Memset for nehalem to check values >> there are some issues with reading subtimings properly...software will read them out +2 on most timings

[Momento Mori]

I am having a hard time getting my system past 2.8Ghz maybe I am just doing something dumb, here are my settings + relevant configuration. I would be greatly appreciate any suggestions. I would like to hit a bclk of 175 for a stable 3.5Ghz rig if possible.

Hardware:
12GB OCZ Gold 1600 (8 timiings)
i7 920
GA-EX58-UD5

Settings:
BIOS: F3

Turbo: enabled
EISTE: disabled
C4/5/6: disabled
LLC: disabled
CPU multi: 20
QPI: 36
Uncore: 16
Mem: 8
CPU voltage: 1.26875
QPI/VTT voltage: 1.15
CPU PPL: 1.8
Mem Voltage: 1.64
Bclck: 140
SPD: manual [8-8-8-24]
IOH/ICH voltages: auto / optimized defaults

If I am missing some relevant setting you need to see let me know what and I will add them.

OK, I've had my X58 extreme now for almost a week without issue. Today I put on my cpu waterblock and test my 3.6GHz OC I had on my stock cooler and it was fine and just under 70C after an hour or so.

I reboot to try to get a 4.0GHz OC and it gets stuck in this auto-reboot mode. It won't even post a post code to figure out what's up!

I try cmos clear, quick unplug power cord with no luck. I finally leave the power cord unplugged for a while as I surfed for some answers on my other rig. I plug this back in and viola! I'm up and running. I decide to upgrade to latest BIOS as I was on F3, so I download and copy to flash drive. I reboot to flash and get stuck in auto boot mode.

I power down 10 minutes or so and I get back in, load optimized defaults and reboot to flash without my overclock and the stupid thing auto-reboots in less than a minute of being turned on. I power down and get back to flash latest BIOS and it still auto-reboots every time I warm boot or don't wait long enough on a cold boot, but it always stays running without error on first boot?!?!!

HELP!!

I always flash, load optimize defaults, then manually put in stock memory speed/timings/volts then save and boot to avoid reboot hell. Sounds like auto settings in bios dont work to well with something and likely the ram. I would try setting correct memory values first.

I imagine it takes time/difficulty for bios to be capable of making auto settings work on all ram comers, especially this early in game. My OCZ rated 1600, cas 8, 1.65v was auto set to 1.5V Cas 6 1200. With my corsair, auto was getting closer to stock.

man, this thing is freaking me out, from f3 bios i flashed to f4k, got it stable @ 4ghz @ 1.375v vcore and qpi/vtt 1.315v, also got 4.1ghz stable , 4.137ghz stable, and then 4.2ghz crashed after 8 hours 38 mins of prime, then i flashed to f4n , and i couldnt get it stable , or it needed more vcore then with f4k,

now i went back to f4k and it needs more vcore than before to get stable , wtf is going on

so now ive come back to f3 just running this again and then i might go back to f4k again

is it posible i stufft up my cpu ?

you will never be able to select 23x multi in bios on 940

Sorry let me clarify...22 is the only multiplier I can select, no less, so I cannot try say, 21x200. I have not seen anyone else having this problem. The moment I change it in the bios it flips right back to 22. So I have only a 22 or 23(with turbo) multi right now.

overclocking nehalem in particular is a LOT more complicated than just mimicing other users

I agree, I meant I was looking to them to see how high some of their voltages were without frying their cpus, so I could freely work within those ranges.

i would suggest higher QPI/VTT >> somewhere 1.5 or 1.55 particularly if you are going to run vdimm at 1.8v or more

for high NB speeds you will have to jack up uncore and RAM volts even more

185 bclck x22 (turbo on), vcore @ 1.525, qpi/vtt @ 1.54 = no post (all other settings same as above)

how are you setting RAM timings in bios....try auto and manual set...use latest Memset for nehalem to check values >> there are some issues with reading subtimings properly...software will read them out +2 on most timings

Settings are 9-9-9-24 with trc at 34 and the rest on auto. Running a bit loose on timings to get the cpu squared away first. Memset annoys me since it only runs at 96 dpi, which is really tiny at 1600x1200 res Ram is 4x1 Corsair TWIN3X2048-1600C7DHXIN 7-7-7-20 @1600 1.8v ...loading the xmp profile sets the vdimm down to 1.55 I think.

BTW Dinos, as far as I am concered you are THE authority on OCing GB boards. Thank you for your advice.

i think i had the same issue until i disabled turbo

[mascaras]

F4L and F4N have my multi locked up at 22 on my 940, whether or not I have turbo on.

Hi

yep , i aslo noticed that , with F4L & F4N Bios we can only change CPU multi in Advanced CPU features (and need to be the last setting before SAVE)

Thank you for that workaround, I thought I was going crazy
This has allowed me to test some things out, and disprove my theory about the 180 bclck being my ceiling. I can do 200x19 no problems, 200x20 bsod during linpack (at 1 notch below 1.55 vcore!) So I am stable at 180x23, or 200x19, but no higher regardless of Vcore (which suggests something besides cpu holding me back), yet my QPI/Uncore is running faster at 200 bclck than 180, which in turn suggests that QPI/Uncore is not the cuplrit.

I know they are all interconnected, and I (think) I have the basic grasp of how it is all supposed to work together, but this still makes my head hurt and I am not a stupid guy, really
