Overclocking GIGABYTE GA-990FXA-UD3 Rev3 (FBd bios) with FX-8350 Piledriver

Just a quick heads up for everyone who's playing with the UD3 and Piledriver.

GBT recently released the UEFI BIOS for AMD on the 990FX series and I had the opportunity to quickly get a hands-on testing. As you can imagine, going from regular to UEFI BIOS comes with a whole lot of issues and problems and the first release didn't do so well for overclocking. I've quickly tested this combo for overclocking capability and the latest FBd BIOS fixes most of the issues I had before. The board's playing quite nicely HTT-wise - better than the UD7 in fact. There's still some stuff missing (DDR3-2400 divider for example) and some bugs (HTT overclocking when XMP enabled might not always work), but in general it's now working fine for overclocking :).

If you're on FA or FBa BIOS ... definitely flash ;).

Didn't have the time to do much testing, so just ran a quick 3DMark11 Physics test on air cooling.

Have fun!

Massman, push it more, I got 5200 MHz 3D11 :-)...

Code name: Zembezi but you have FX-8350?

Reason is CPU-Z version

UD3 really handing such a load :confused:
Because UD7 (Rev. 1.0) isn't.

But my CPU cooler wasn't mounted, just on top of CPU, and only used one fan ... 4800 8c isn't that bad :D.

The PWM gets quite hot on the UD3, so had a fan on it. Not sure how it'll do with CPU under LN2 ... might test later.

Didn't have an issue with the UD7 other than surprisingly low CPU overclocks. Got to about 6300 with 8c8t and 7000 6c6t (core 3-4 bad). About 7500 2D stable with 2c2t.

Very nice indeed...

Are there any other 990fx boards that have a beta UEFI bios avail?
Will the older revision UD3's get an updated UEFI bios?

Trying to find a rev3 UD3 board but no luck....would grab one of an older revision or the UD5 if i knew they have/will get the UEFI bios in the future.

Thanks

Small update - I am done with the UD7 at the moment, trying the UD3 to see if I can push the HTT clock a little bit higher. Seems to be working fine:

The UD7 was stuck at 335MHz HTT frequency. That board has a 6-layer PCB. The UD3 can easily do 350MHz HTT and has 4-layer PCB. I think it's obvious why I am trying the UD3, not much more explanation is needed. The efficiency on this board is off for some reason, I think I'll have to re-install the OS to get the right efficiency back. That will be something for later this week, though. Next objective is to see if I get my good PiFast run back (17.4x) and then Super PI 32M.
