Gigabyte EX58-UD5/Extreme Discussion Thread

[dinos22]

gigabyte changed their colour scheme mainly from feedback of XS users

blue and white RAM slots FTW hehehe

[giorgos th.]

eh,it was about time.....

[jcool]

As far as 12GB of mem working, this seems similar to the whole 4GB vs 8 GB issues with the 775 boards.

The memory ratings are for the triple channel set. They will run at 1600 MHz at those timings. If you want to run 12 GB, you have to run them at like 1333 or so and loosen the timings a bit as well.

I received that tidbit from a Kingston rep and it seems to hold true at least for the 775 boards.

I have 12 GB of OCZ gold 8-8-8-24 ram, but can only install 6GB atm because the True is taking a slot up. I'll be putting her under water this weekend, so I'll be able to use the full 12 GB. I'll let you guys know if someone else doesn't by then.

Well no, that's not the problem here. I can run all 12GB fine at 1600Mhz with 133 or 140 BCLK, even 1700 passes memtest with all 12gb in it.
However, I can't up BCLK and just use 8x or 10x ram mult like with 3 or 6gb it just won't post even at ram speeds lower than 1200

Sorry to bring this up again, but does the board support recovery from floppy? eg I would copy awdflash.exe and the bios bin to a floppy and try to boot from it.

Don't really want to pack this system up because it is all so neatly built.

[CodeRush]

Guys, what do you use to change BCLK under Windows?
I tried EasyTune, but it drops i7-920 multiplier to 20x.
I'm using SetFSB (2.1.84.0) with ICS9LPR426AGLF clock generator with PPL M = 16.
On BCLK 170 it shows 570.0 FSB and +1 FSB is +0.3 BCLK.

[jcool]

Guys, face it, the i7 920 has a mult of 19. Anything more is just for show/single threaded apps. There is no way you can have a mult higher than 19 on a 920 for all cores.

[CodeRush]

jcool, you are wrong.
i7-920 default is 2.66 Ghz (133x20) for all cores. x21 for all cores if TurboBoost enabled in BIOS. x22 for only one core and TurboBoost enabled.

[dinos22]

you are using the wrong clockgen

you should be using the one that ends witha 4E something i forget

[CodeRush]

dinos, u rule.
It is ICS9LPRS514EGLF.

[dinos22]

yeah dude thats the one

[dinos22]

i prefer the other one because you can jump in smaller increments

[CodeRush]

It's all OK, but i can't use it.
It shows BCLK correctly, but hangs my system up on clicking Set FSB. I repeated boot-ICS9LPRS514EGLF-Set FSB-reboot sequence 5 times and reverted back to ICS9LPR426AGLF. Will try again later with different bootup BCLK.

Edit: 918BKL works perfectly. I only set PPL M to 21 to get smaller increments. Thanks, X.T.R.E.M.E_ICE.

Hi I guess you guys are already using your self built/modded phase change coolers on your Gigabyte X58-UD5 ? I'd love to give one a go!
Not blowing my own crumphet but I've got one of the Gigabyte X58 DS4 on it's way.With a 920 So looking forward to seeing if all the exciment is justified.The last Gigabyte board I had was a 939 socket 5 years ago and it was bullet proof.I changed to a Asus when I made the BIG mistake of going to AM2 as an early adoptor.(I hope I'm not making same mistake being an early i7 core user) (Me thinks not)I hope.
I never bothered with Core Duo/Quad would have liked to but other bills to pay.Bad excuse but true.So I jumped at the new i7 cores and a Gigabyte X58 DS4 at £164 inc Vat and £220 for the 920 cpu.Planning on watercooling it with a Swiftech Apogee Drive 350..I just need to find an adaptor to fit it to a 1366 socket.Anyone know of one.I may try makingmy own ifit's just a plate that's needed.Any one made their own 1366 water block adaptors yet? I know you phase cooler guys are good at this sort of thing.

Hope my sentence structure is ok for u? Plz comment He He

[typer77]

have you tried 1.55v+ QPI/VTT

With F3 bios, there is no way to get it working on 200Bclk with 8X multi?
How about the current F4 beta BIOS?
thanks in advance!

I have handmade waterblock and plate. It is not so beautiful, but it works.

wtf are you talking about? lol. I've been using 20x (now 21x is permanent with the later bios' in multi-threaded apps) since I bought the board two weeks ago.

You saying that there is no way is like throwing yourself in front of the short-bus. Last time I checked, prime was multi threaded.

[jasonelmore]

jcool has been hating on the i7's turbo mode. He came over to saaya's vtt thread and called me out on having 21X200 in my sig. "you know your not really running at 4.2"

no shirlock

and the multi is 20, not 19

[Lukee]

for QPI/VTT
wow ROFL
u crazy dude

That's the only way I can get 211 Bclk.

Maybe there is another setting which will allow me to get that and lower qpi/vtt, but I don't know.

If someone does know, please share.

[Lukee]

I got EX85-Extreme and Core i7 920 about 2 weeks ago.
Problems:
1. MoBo sets tRFC timing automaticaly, dispite of manual setup. Solved in F4j BIOS.
2. Strange starting sequence with 4 soft-offs before starting actualy. One soft-off every time when powered up. Sometimes MoBo falls to endless soft-off loop after failed overclocking. Clear CMOS and BIOS profiles are solutions.
Goods:
1. Over 220 BCLK stable on CPU and NB water cooling. SuperPi 32M result
2. Tri-SLI support.
---
dinos22, very good SPi 32M result.
What is your maximum unstable BCLK? I have ~222 on cold water. CPU-Z validation
Is there CPU or MoBo QPI-Wall, what do you think?

What qpi/vtt are you using for 220 Bclk?

Has any user of a UD5 flashed the bios with the extreme bios ?

[Xello]

Hi guys, finally got my main system assembled yesterday. Flashed to F4J. Fresh Vista HP 64 install.

I'm trying to do a prime blend run just to verify stability @ stock, and so far i've tried it twice and had app crashes. It done it last night and i assumed it was because i hadn't turned off sleep mode (it was asleep when i woke up), but after sorting out the windows settings and leaving it on while i was at work i've come home to another app crash.

Is there anything in particular you need to do with prime on the new i7's? I haven't touched any of the settings in Prime [64 bit version] (i remember changing the memory available option to 12 from the default 8 with the QX9650, but since cache size has changed now i haven't touched it).

The only bios settings i have changed are raid-related, plus the adjustment to 1.66v dram and 12x memory multiplier for ddr3-1600mhz. My clock on the memory is actually 810mhz (ddr3-1619), could that be the problem as it is a slight overclock? I'm not sure how i'd sort that though, it seems to be based off the bclk or something which i've read goes up and down a bit anyway.

Also, can someone verify that the motherboard temp from Everest is accurate? It idles @ 26~ and is currently 36 under prime blend load. I guess this makes sense if it's just a pci-e switch.

Ah, My qpi pll is only 1.24 or so, do you think by raising this, I can lower my qpi/vtt?

I'll try raising it and see if I can get 220

Thank you so much!!

[CodeRush]

... do you think by raising this, I can lower my qpi/vtt?

I don't know. Try it.
It seems QPI wall is processor-dependent and good voltage settings may increase max QPI by 1 or 2, not 10, IMHO.
