Stomx Notice that not a single case from Gigabyte? And I was thinking why it was so difficult to upgrade their BIOS. 🙂 Instead of do that in 1-2 clicks there were 15 pages of instructions with missing details, 100 different abbreviations without their explanation and at the end missing the file which launch the BIOS update. I saw video where guy to launch update uses this file from older BIOS. My processor was different than in this article but from the same AMD. I was not able to do that for couple weeks Reply

ThatMouse At least your build is slightly easier when ASRock, ASUS, and Intel are a don't buy. Reply

DS426 ASUS and now ASRock. MSI and Sapphire, are you going to make the same mistake?? I've seen this tons of times with various hardware and software vendors: they test in an ideal or mostly ideal lab environment, not accounting for real-world conditions — even if uncommon or rare (but not exceptional as in only a handful of people in the world have certain adverse conditions). Of course, Grandpa will say "they don't make 'em like they used to" and would be correct as 1) tolerances are tighter and there's more resources put into failure engineering, usually making 2) planned obsolescence fairly predictable in most cases, and lastly 3) complexity adds more failure points.

Did you look at the chart in the article from the Gamer's Nexus video showing 8 reported failures from Gigabyte? And that's only from data collected from a Google form in the ASrock subreddit, so probably not too many Gigabyte users there. The data is also at least a month old at this point. As far as we can tell from the evidence we have (which is lacking), both Gigabyte and MSI have at least somewhat of a failure rate, if significantly lower than ASUS or especially ASrock. Reply

Though formally you are right Reply

TechieTwo FWIW – BIOS v3.50 for the B850 Pro RS has been out since 9/26/25. It may address some voltage issues often seen on new model release mobos. IME all the name brand mobos including Intel have had some issues over the past several decades so I don't see these issues as a one-brand/model issue. I used and recommended Gigabyte mobos for years building quite a few PCs and when AMD delivered the FX-8350 CPUs the Gigabytle mobo VRMs would overheat and go into limp mode. It took two years before Gigabyte came out with new mobos with proper VRM designs to handle the FX-8350 and higher current demand AMD CPUS. During that 2 year period Gigabyte told customers over and over that there were no problems yet the issue could be documented easily with a CPU stress test. The only mobos that I have had fail in 30+ years of building PCs for Biz and personal use were Asus. So in my experience no brand is immune from issues from time to time. I agree they should do better but CPUs and mobos become more and more complex with each new iteration which is why it takes several BIOS updates to sort thru issues. Reply

Beyond that, as an initial ASrock /9800X3D owner who has now lost one CPU and switched to an ASUS board (would have gone MSI or Gigabyte but there aren't a ton of ITX options out there), I would say all of these stats are a little high for comfort as far as I'm concerned.

User of Computers "hey, my CPU got eaten by my motherboard for the second time. I'm just going to replace it again and gee whiz I hope nothing bad happens to it!". Motherboards shouldn't kill CPUs, but not getting a different one after the first 2 CPUs died is an… interesting choice. Reply

  • Investor positioning can change fast
  • Volatility remains possible near catalysts
  • Macro rates and liquidity can dominate flows
