[Official] Gigabyte GA-890FXA-UD5/UD7 Owners Thread/Club - Page 388

Currently working on OC'ing it. Have it at 4.4G @1.4v @40oC under water cooling. Only got the 6100 because I can't get a 8150 or 8120 anywhere. Maybe get lucky and Gigabyte will come out with a BIOS upgrade to unlock the other 2 cores

Does not work for my 2.0 board. I get a bad check sum error after restarting.

scratch that, ITS WORKING! I did not clear DMI pool data. There's a option to choose this on the @bios screen.

Now all I need is a FX chip to test it lol

That's the important, the BIOS work but does the CPU?

Blitz, I believe you might be thinking of the 6850, which slots between the 5770 and 5850. A 6870 routinely is above a 5850 in benchmarks I've seen (games or otherwise).

A link with theoretical comparison: all numbers.

A cross-fire pair of 5770 cards was just a touch above a 5850 for the time, and would mostly tie a stock 5870.

2x6870 cards will be a pretty good combo, and should act more like a 5970 card in terms of raw performance (6 series scales much better with Crossfire than the previous 5 series).

I checked a review here that shows a 6870 vs. 5850. The 6870 wins pretty much every time.

6850 cards, on the other hand:

Suffice it to say, 2x6870 will provide plenty of performance (I'm happy with 1x6970 myself, and even my old 5850 can still churn out good FPS). If you're having cooling issues (assuming you aren't overclocking) is it possible to put the cards in slots 1 and 3? I know this would make each slot X8, but that is all the cards need for bandwidth. Downside: you'd need to find longer Crossfire straps. If you're really not afraid, you could try liquid cooling the top card at least, or possibly both, but I would try spacing the cards apart more first...cheaper, and will probably be effective enough.

Also, in terms of your case, how many fans do you have in it, and how much do they flow? The model in your signature doesn't have all that many fans (not what I'd consider enough for the amount of airflow those cards need). Maybe try some higher flow fans to improve airflow, and be sure to provide positive airflow pressure (more intake than exhaust). If all else fails, try another case.

So it looks like it works with bulldozer but not properly with thuban. At least it shows the board can run bulldozer, seems like they weren't lying about the size constraint of the bios chip. +rep for the update.

Bit academic for me now as I have an 1100t on the way but still nice to know

I am so happy about this cuz my UD5 runs soooo well I didn't want to part with it in order to get an FX chip. Hope this Bios dose OK

Where you read this? I have the bios and its fine with my CPU

Got my FX6100 stable at 4.6Ghz Going to push it further tommorrow
