***Official*** X79-UD7 Owners Club/Discussion/Info

I am not sure of a recall of the boards in TW, but I think what they meant to say was that the BIOSes before F7 were recalled. Then they said that they also have lifetime warranties now, and that users can just return their boards i think.

I think in the USA its mostly the same, but there is no recall. That word wasn't translated correctly through google translate and so it is kind of a hard mess to fix up, now all sites like TPU post in their headlines Recalled X79 boards! lol I mean that really isn't true.

But i guess it would fit if people read more carefully recall of BIOS, i guess in Chinese they have other words that also mean recall.

I am not 100% sure on all points, but I am sure there is no recall of boards. Maybe it had something to do with some people saying that in TW warranty RMA is denied if the board is broken, like physical damage and that is what that press release was for, to say even if your board is damaged we will accept it.

GB USA is supposed to release their own pres release, IDk if they did yet or not.

Now people talking about OC being limited by BIOS F7, let's put something straight, if you overheat your board your OC should be limited. And BIOSes like F4 and F3 and F2 all would throttle the OC if the board was overheated. The user GMEUP PMed me about this problem and I think he posted in this thread, i told him to toss a fan over the VRM, he did and it fixed his problem 100%. It was overheating. I am thinking that maybe with some boards the PWM firmware wasn't flashing correctly or all the way, maybe the OTP thresholds weren't correctly set, and GB wanted to address this.

BUT what is very clear is that F7 has the same OTP and OCP thresholds as previous BIOSes, just 80khz lower switching frequency and one turbo voltage response setting removed. I think all F7 does is prevent the users from maxing out the PWM settings so avoid the board breaking because of it. A lot of users will just crank up the switching frequency, even though it does nothing for the GB X79 boards, they do it anyways and that can lead to overheating.

I haven't flashed my G1 Assassin 2 with F7, but I will and report back my findings for those interesting. i will run side by side comparisons to see if previous and the new BIOS have really any different OC potential.

What is clear and has been for weeks is that VRMs on SBe get much hotter than anytime in the past, this is probably due to having components on both sides on virtually every board, sure you might have a piece of metal under neath on some boards, but that is just a slim piece of metal not a heatsink, and there is no airflow underneath. Then you have SBe being so power hungry that at 4.8ghz it is pulling ~300 watts, count 85% conversion so input 350w. That is a lot of power. The VRM components have to take a lot of heat and the PWM temp restrictions have to be very stringent and guaranteed to work, BIOS F7 probably runs some type of self test to make sure they do. The PWM firmware needs to be updated, so maybe this is what that is all about.

But IMO what i don't expect to happen is any change in the MOSFETs, as they really aren't to blame in these instances. I think we might see maybe some bigger heatsinks, or maybe some manufacturers adding VRM fans instead. Of course as the power delivery to these new CPUs is better analyzed, we will get better PWm management, and hopefully no more of these issues. It almost makes you wish you had an analog PWM lol, so users couldn't mess with the settings then blow up their boards and blame it.
