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.

Do you know what a transistor is?...here, we are talking about a Metal Oxide Field-Effect transistor, or (MOS)FET.
Please, don't talk about things you don't know about. I'd know, I'm extremely guilty of that as well.
You know CHiL? The voltage controller used on all of AMD/NVIDIA's reference boards? Yeah, they got bought out by IR a long time ago. Gigabyte has used IR for a long, long time on their boards.
Have you tested all the top models of each manufacturer's boards to find these "NIKOS" Power MOSFETs? No?...didn't think so.
The problem here is not the MOSFET. It is the OCP and OTP circuits to blame. The board should throttle the CPU or even simply shut down when the VRM section gets too hot. This board didn't shut down until it caught fire.

Actually in this instance it was the fet that was to blame. It was a faulty fet, they happen.
It would be nice to have a VRM measuring system that actually worked though. None that I am aware of monitor each fet/driver IC and only measure PCB or heatsink temperatures at the most with reference to temperature. Bad fets often enter thermal cascade long before the PCB or heatsink temperatures reach the thermal tripping point.
All along the watchtower the watchmen watch the eternal return.
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

I completely agree with you. I really loved my P5Q Deluxe with backplates on the vrm sinks. Thats something that I wish was done more often. Its too bad that stock aluminum heatsinks still sucked. I don't understand why these little aluminum sinks. Once I bolted on a couple of enzotech mst-88 sinks to the stock backplate that was the perfect solution.
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 :/
All along the watchtower the watchmen watch the eternal return.
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.
Particle's First Rule of Online Technical Discussion:
As a thread about any computer related subject has its length approach infinity, the likelihood and inevitability of a poorly constructed AMD vs. Intel fight also exponentially increases.
Rule 1A:
Likewise, the frequency of a car pseudoanalogy to explain a technical concept increases with thread length. This will make many people chuckle, as computer people are rarely knowledgeable about vehicular mechanics.
Rule 2:
When confronted with a post that is contrary to what a poster likes, believes, or most often wants to be correct, the poster will pick out only minor details that are largely irrelevant in an attempt to shut out the conflicting idea. The core of the post will be left alone since it isn't easy to contradict what the person is actually saying.
Rule 2A:
When a poster cannot properly refute a post they do not like (as described above), the poster will most likely invent fictitious counter-points and/or begin to attack the other's credibility in feeble ways that are dramatic but irrelevant. Do not underestimate this tactic, as in the online world this will sway many observers. Do not forget: Correctness is decided only by what is said last, the most loudly, or with greatest repetition.
Rule 3:
When it comes to computer news, 70% of Internet rumors are outright fabricated, 20% are inaccurate enough to simply be discarded, and about 10% are based in reality. Grains of salt--become familiar with them.
Remember: When debating online, everyone else is ALWAYS wrong if they do not agree with you!
Random Tip o' the Whatever
You just can't win. If your product offers feature A instead of B, people will moan how A is stupid and it didn't offer B. If your product offers B instead of A, they'll likewise complain and rant about how anyone's retarded cousin could figure out A is what the market wants.
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.

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.

I only read BIOS recall, am i alone or what? I don't see board recall.
I am talking about the official statement, website article i don't put any credit into, they got their info from the same place.
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
