Gigabyte 970A-UD3 rev 1.2 vs 3.0

post #1 of 5
Thread Starter 
What is the difference between these revisions? I plan to use this mobo on my FX-8350 and 7950 3Gb.Is this a good option? (I'm looking for good value)

There is an official thread: http://www.overclock.net/t/1048912/official-gigabyte-ga-990xa-970a-series-owners-club-help-thread-fx-8350-support-added

In that thread and others in this web many people has problems with 3.0 revision, rev 1.2 doesn't have UEFI BIOS, but is more stable, etc...

Anyway, still a good motherboard, i have one GA-970A-UD3 and I'm not unhappy at all, but BIOS options are very limited, has a terrible VDroop, etc... i recommend you other motherboard like ASUS M5A97 EVO R2.0, in my country at least cost about the same.

I noticed 970A-UD3 has 8+2 phase count, compared to 6+2 of M5A97 EVO R2.0 .

Also, I wrote 970A-UD3 1.2 or 3.0, and it is my understanding that only 1.0 has a bad vdroop

Rev 1.2 too, i have one, and LLC only has two settings, and at extreme it overvolts a lot...

8+2 phases on GA-970A-UD3 are not digi, in ASUS 6+2 phases are digi that are best...

Other inconvenients with UD3 is that settings for VCore or CPU-NB VID only allow increments in +0.0125V, you can't set a determinated value, and believe me that M5A97 EVO R2.0 is best...

I've got the same board, and I concur with everything he says. The vdroop is *especially* annoying, makes overclocking very, very tedious, and makes me feel like I'm not getting the most from my chip. Have to try each vcore setting with each LLC option to see which one is optimal/stable, as they don't always scale the same at different voltages. I got mine (R1.2) for an awesome price, so overall can't complain too much, but the Asus is probably the better overall board, despite the technically higher phase count on the 970A-UD3.
