PcCI2iminal, nice one!

I just noticed on newegg that they've listed them as a limited edition. Would anyone know how many boards Gigabyte are making?
Hope Australia doesn't get left out!

was hard to find two days ago,but today my wife did a quick search and now many retailers selling on web

Well yeah PcCI2iminal you need 3, one for you, your wife and the 3rd for the kids to play with

Now you have to get 3 CPU's to go along with that also
But I bet you have that covered also

Hi Buck,
one more X58A is in my way
the family is big

i think cpu will be not a big problem, a few months ago Movieman sent me two 990x ,great retails ,but now its time to play really hard with them ^^
i can smell 7Jigazzz

As far as I can tell they only made 4, one for me and 3 for PcCI2iminal and the other boards for the reviewers.

need to tell Gigabyte to send more than ,because we have 5 kids ...
and he have plan for one more

no info?

[dinos22]

hey criminal how come u're buying so many of them, most ppl just need ONE lol :p

Hello Dino,
yes you rite and include me in the list

but dont forget about my wife
Yoko is ready for her solo career and she owns two of this piece of art ^^

Yoko and I made a quick run last week (on ustream for 70ppl)

that 990x scored
CPUz at 6732MHz (before - 6586MHz on ASUS R3E)
3D05 done at 6400MHz (before - 6250MHz on Classified 4way)

good boost for a start

F3 bios - has a bug on bclk and multiplier adjusts, just one hit on any of them and the blck or multiplier will be increased by x2
F4 bios - the onboard bclk/multiplier adjust control is dead now

F4 bios - the onboard bclk/multiplier adjust control is dead now

Which means in version F4 they fixed the F3 bug...

[PcCI2iminal]

yes Leeg, easytune works great with F4
i will try that F5 bios

[NoGuru]

That's a nice boost over the ASUS, great work PcCI2iminal.

I will see if my board will boot after washing in the sink. Putting the Ultra Durabile to the test, lol.

Yeah let us know how F5 is. If I get the board running and have time to test I will post results of F5.

[markwrc]

i just brought one of these, they are now for sale in the UK £259 free shipping, which is about $418 including VAT of 20%

Congrats and welocme to XS.

[Biker]

Should get mine in tomorrow too

Edit: make that today

Testing F5B bios now.....

[Lsdmeasap]

F5b BIOS working great here for me, warming up for dice this weekend!

Just started getting into Pi 32MB, so don't laugh to hard, but the OC Board has taken me to my first few times to get sub 7s with X58!

I had this setup in dual channel for competition, in case anyone is wondering.

I'll have a review up on this board in the next week or so hopefully, dice session this weekend then I'll wrap up the review. For anyone still on the fence about this board, but looking, don't think twice the OC board is amazing and I'd recommend it to anyone looking for something better than their older gen X58 board. Hicookie and Gigabyte have done a fantastic job with this board, I am impressed every time I press the go button!

F5b bios notes:

Load Line Calibration level 1 gives significant Vdroop at 100% load. 1.265v down to 1.248v (DMM).

Load Line Calibration level 2 overvolts just as much at 100% load. 1.275v up tp 1.296v (DMM).

Vqpi / VTT overvolts slightly. 1.295v set in bios 1.33v DMM.

I have not tried any other bios I just jumped straight in with F5b....

Testing continues

[Hondacity]

measure vdimm accuracy.... its soooo gigabyte lol

[Biker]

Yup Vdimm is not exactly spot on.

My board is overvolting .03v with F5b so 1.5v bios = 1.53v DMM...

Well at 1.5v anyway

[Biker]

Well this thread is simply on fire LOL

Anyway, just completed and sent off my fifth build with this board so a few observations...

All builds have been air / water and not for extreme overclocks just 4.16-4.5ghz with the absolute priority being stability and hopefully longevity

A comprehensive smorgasbord of data and info regarding how this board performs with extreme overclocking can be found in the reviews section.

This is just a few notes for users shooting for stability and reliability.

I have been using the F5b beta bios in all builds so far...

Observations:

At the above clocks the board's bios and voltages behave pretty much exactly like the X58A-UD3R rev 2.

Load line calibration I have already mentioned in a previous post and other voltages tend to overvolt slightly depending on what clocks are being gunned for.

Make sure you get a DMM to check... no excuses for not having one any more

The main thing I have found is this board requires slightly more vcore for stability than my best R3E using same clocks and settings.

I am not sure whether this is immature bios or just me

Having said that that this R3E is exceptional and the other R3E I have does not even come close to it, especially on getting away with low vcore at 4-4.4ghz full load scenarios.

The southbridge stays really cool which is nice but the IOH and VRM area can get pretty toasty under load so direct cooling in that area is recommended.

Other than that all builds have gone smoothly and no reported issues so far so in my limited experience a solid board which also appeals to people in that they like the fact that it has all the features they want and none of the useless clutter they do not, well, perhaps save for a few onboard sound ports

[sin0822]

increase the switching frequency and your required vcore could drop because of reduction in ripple.

[thebad]

Have played with mine for about a week now. Coming from an the original eVGA Classified E760, I am a bit disappointed. It seems to not be able to overclock my 980X with the same voltages and it is not as stable. Wish it would also have the latest RAID option ROM for SSDs. The Northbridge runs 10C hotter than the classified. The layout is great but so far it is about the only thing it has going for it. The classified could run the PWM switching frequency to 1210 and 1333MHz. (I had it set at 1210) 1000MHz seems weak. The overclocking recovery can also be very annoying as it resets my overclock even when I reset the computer anywhere before Windows starts loading which I do quite often when I realize I set something wrong in the BIOS.
The VTT is overvolted by 0.02V but the Vdimm is undervolted by 0.007 to 0.02V depending on the setting on my board...

That's interesting.... all of the five I tested overvolted Vdimm slightly...

[zalbard]

Are you both using DMMs and not some software readings?

[sin0822]

it depends on BIS version, a lot of this voltage stuff does. For the kicks of it try BIOS 014, it should predate any retail board, its voltage other than VTT were pretty dead on.

VTT was always overvolted on every BIOS except the F4 BIOS. I haven't tried F5.

Anyways you have no idea about switching frequency I am very sorry to say (the bad) 1mhz is not weak, and 1.333khz is over the top, its actually the highest of any X58 PWM. Switching frequency is only directly related to ripple, over shoot, under shoot, and transient response, and some of those 7ghz OCes are done at 600khz setting! lol many times lower switching frequency= higher current output for the mere fact that efficiency isn't below 80%. Its not a big changer of your required voltage, because to be honest voltage is really not that great of a number, current is, hook up a current meter, there are many retail ones from zalamn, and measure your input current on the 12v rails, you'd be surprised what that looks like when you change voltage.

[markwrc]

on my OC using F5B, nothing gets over shot apart from QPI, which it is only by .025v which isnt so bad

[thebad]

Zalbard: I am using a DMM indeed. And with BIOS F5b.
Sin0822: You are correct that I don't really know what the impact of the PWM frequency is beyond the overshoot and the fact that in my experience on the eVGA board, I was able to lower voltage by going from 940kHz to 1210kHz and gained stability. 1333kHz seems to be overkill indeed as I saw no benefit from it but 1MHz does not appear sufficient to match what I had with the Classified board. I was hoping some design differences in the power regulation would make the OC better than the eVGA at the same frequency. I am just disappointed. I think it is the reason why I am needing to increase the Vcore by a couple of notches on this board to reach the same 4.5GHz clock. I am not into extreme cooling. Just an everyday extreme overclock. For that purpose, this board has yet to show anything but I am still tweaking.

[Biker]

Are you both using DMMs and not some software readings?

Yup confirmed with a DMM on all 5 with F5b bios...(have not tried other bios versions at all).

I also played around with the PWM frequency a bit but still could not get Vcore as low as my R3E for the same clocks with the same chip...

Not a massive difference but still interesting...

[thebad]

For those of you curious about the voltages on the board read with a DMM
CPU Vcore set at 1.4125V (LLC 2) gives me 1.4V idle
QPI VTT set at 1.395V reads 1.409V
QPI PLL set at 1.3V reads 1.276V
CPU PLL set at 1.8V reads 1.791V
VDimm set at 1.72V reads 1.706V
DDR VTT set at ??? reads 0.853. I figured it is half of the Vdimm.
VMCH set at 1.22V reads 1.238V
