Three Gigabyte motherboards need a critical BIOS update.
Last week a Taiwanese overclocker uploaded a video to YouTube showing a Gigabyte X79-UD3 motherboard smoking and then blowing a MOSFET during a mild overclocking stress test -- the board's CPU VRM just couldn't cope with the stress. Viewers blew off the "blow-up" as mere bad luck in the following comments (which have since been disabled).
But then Gigabyte began receiving similar complaints from numerous customers owning several different Gigabyte motherboards, some of which claimed that moderate voltage-assisted CPU overclocking produced the same explosive results. The company thus began an investigation which revealed to be a problem with three socket LGA2011 motherboards: the GA-X79-UD3, the GA-X79-UD5 and the G1.Assassin 2.
The problem, according to the report, is a combination of the board's bad quality PWM components and bad firmware. The company has released a quick fix by way of a new BIOS which prevents burnout by throttling the CPU when subjected to extreme stress (and save VRM). Unfortunately, this prevention means that the overclocking feature has been disabled -- the main selling feature for all three affected boards.
That said, current owners can keep their motherboard and use the new BIOS, but the overclocking ability will be eliminated. If that's not satisfactory, customers can return the motherboard to Gigabyte for a free replacement when the corrected version becomes available. Meanwhile, the company has pulled all three boards from store shelves and virtual retailers.
Gigabyte will likely issue a statement soon on when consumers can return their GA-X79-UD3, GA-X79-UD5 G1.Assassin 2 motherboards for replacement, so stay tuned.
We've learned from Gigabyte that the new F7 BIOS does not disable overclocking. The company claims that it has hit 5.3GHz with the X79-UD3 and a 3960X using the F7 BIOS. Furthermore, Gigabyte claims that the only faulty part of its motherboards was in the BIOS. As such, the recall is for the BIOS itself and not the motherboard. Users who are not comfortable with updating the BIOS themselves can send their motherboards into Gigabyte customer service to have them updated.
Gigabyte this evening released the following statement:
