GIGABYTE's mobo X79-UD3 happens self-ignition and burning!

[Eldonko]

There is new Trident??

quadchannel tridents? probably not? i dunno hence questioning minds...

[Eldonko]

G.Skill has told me that they dont have Trident anymore so if there is new stuff I demand to know where to get it and the specs!

Did you hear that he got the board replaced with and Assassin 2 and new CPU(he went from 3930K to 3960X!) and memory. Maybe i am a bit behind.

so if i get a ud3 n the pwm blows up i get an Assassin 2 ?

gettin the heatgun n cameras ready lol

you're in canaduh, gigabutt will take forever to respond to your email lol

if you were in taiwan, gigabt HQ will send 3 engineers with gifts lol

your right
it took them almost 3 months to rma my p67 b2 board

was like pullin teeth to get a p67 rma from gigabut only got the runaround

bought a gene-z
sold the ud7 the next day for cheap

wish i made a video
they woulda sent stripers a g1 assasin and a 6990 lol

i rather have a gene-z

my freind Radaja won a prize a gigabut board

over 3 months he has yet to get the board or other goodies n he in the US lol

when i was workin in china i use to get freebies daily lol

[STEvil]

best is individual heatsinks, or fets bolted to heatsink (used to see that back in the day..) but its less efficient on the manufacturer end, so we put up with crap :/

I guess I have three things to say, after having read the thread to this point:

1) The guy wasn't being smart. He failed to cool the VRM when using water cooling. If a board he uses like that catches on fire, he should be punished by being denied replacement instead of receiving free upgrades. This guy isn't going to learn that what he did was stupid.

2) In this PARTICULAR case, I have to agree that it's possibly a bad component.

3) For those of you defending him because temperature protection circuits are generally present, you're not standing on good ground. It's not good practice to count on an emergency system to be routinely used in general operation. That alone should make you re-examine your perspective. Since they're popular according to my sig, let's throw in a car analogy! Counting on VRM high-temp shutdown is like driving without breaks because hey, your airbag will save you, right? Just like when it comes to the electronics this analogy is tied to, the answer is "Yeah, maybe." One thing it definitely isn't going to save you from is an excessive peak transient. A FET will just blow up and the protection circuit would have insufficient time to react.

A motherboard which supports CPU's where one of the standard cooling solutions is water NEEDS to have a viable passive cooling solution on their MOSFETs. And I am sure they have, this component as sin0822 so kindly linked the datasheet to, can take anything from -55 - 155 degrees Celsius and operate normally. It does not however have a built in fail safe for over heating. (As far as I can see at least) However you will find this function in more advanced MOSFETs and VRMs like the 78xx series.
So the motherboard needs to have some surveillance on this, and it does, you can check VRM temperature in the BIOS, however it does not have a temperature sensor on each MOSFET so if one gets out of line it can't necessarily throttle back.
Gigabytes fault? Hardly... components fail, it happens, its rare, but this just gets way too much attention.

Oh, and Merry Christmas everyone! =D

[Warwian]

At least it looks like Gigabyte is taking this issue very seriously as they've started recalling some of their X79-boards. And as a temporary solution to these problems they've released an update to the UEFI/BIOS which limits overclocking and throttles the CPU during stress.

just affirms my statements, "stupid gigabutt product" and "recall" lol

@ least this time they recalled a product

in the past people stuk in rma loop

like my rma loop with p35c-ds3r
6 rmas in 8 months

[matari]

Gigabutt got caught using cheap components. Wonder who else is too.

[Hondacity]

why would a manufacturer not stress test their boards? its just stupid. selling these in thousands and not testing it(bios and hardware)

[mockingbird]

What are they going to replace those IR HexFETS with?

Gigabyte Recalling X79 UD3, UD5, G1.Assassin 2 Motherboards

[ChinStrap]

Wow. Someone in their PR dept. is having a bad day.

[sin0822]

They didn't say anything about the X79-UD7 did they? Then what makes you think they will recall the FETs. THis issue has nothing to do with the MOSFETs.

I don't have a great deal of insight into this story but it seems like there might be firmware issues with the PWM on the UD3, UD5 and the Assassin 2. If this is a quality issue or not is of course hard to say, but I remember reading something about there being suspicions of bad quality PWM components also playing a role in this. Anyway, I trust International Rectifier's products (which I believe they use on the UD3, UD5 and Assassin 2?), whether it's the new IR digital PWM or the IR MOSFETs. And I'm convinced Gigabyte will be able to continue using them and that this'll be sorted soon without much of a hassle.

By the way, I find it strange that the UD7 is seemingly unaffected by all this. Doesn't the UD7 use mostly the same digital PWM/components for the VRM as the other boards? Probably not as that would be expensive! :o

[Origin_Unknown]

hold on, the board they gave him to replace the faulty one is also in the recall list? lol

[sin0822]

I only read BIOS recall, am i alone or what? I don't see board recall.

[defect9]

I only read BIOS recall, am i alone or what? I don't see board recall.

from the article: "The BIOS remedy is only for those who opt to keep their boards, or don't subject the board to extreme tuning. The other remedy, is to return the board to Gigabyte, for a free replacement when the "right" boards are available."

[dctokyo]

The bios update was released but it essentially cripples your board so you can't overclock or overvolt at all. Only other thing is replacement

Gigabyte offered two remedies. First, it issued a BIOS update for existing owners, which prevents this from happening. It does so, however, by thottling the CPU when it's under extreme stress, making these boards practically useless to overclockers, and is only recommended for those who run their setups with mild overclocking that isn't voltage-assisted. The second remedy, of course, is an unconditional return for replacement. Overclockers can send their burnt boards, as well as healthy ones that are prone to this issue, for a free replacement, when corrected boards are available.
