Tri-x OC r9 290 BIOS 015.043.000.001.000000

[BlockChasers]

Just got some new tri-x r9 290s and noticed theres a new bios version.  My older cards all run 015.042.000.  

I also noticed that this new version is setting the voltage at 1.055.  I found that this voltage is causing me instant driver crashes and instability.   I used trixx to offset the voltage by 50 and things are much better now.

Good luck out there!

I just received my first batch and they have this BIOS as well.  At stock voltage it seems pretty much impossible to overclock these cards at all.  I tried bumping the voltage and ended up with really high temps.  Do you just bump the core voltage, or also the aux voltage?  I'm curious what sort of performance you're seeing.

I guess we're the only ones with these newer kinda-bogus cards lol.

I have that as well. I get pretty impressive results after 2 days of non stop tweaking.

If you dont like the bios, just flash the olders ones, they are all on the official sapphire website.

The newer BIOS supports a new RAM type.  Some cards that came with the new BIOS will not work with the old BIOS; vice-versa also seems likely, although I have not observed this myself.

i had the exact same problem, non stop crashes out the box with the new cards. i flashed the old 290x bios on it and 50mv and its stable now

Is the RAM still Hynix?

015.042.000.000.000000 supports:
  4096 MB, GDDR5, Hynix H5GQ2H24AFR
  4096 MB, GDDR5, Elpida EDW2032BBBG_DEBUG2

015.043.000.001.000000 supports:
  4096 MB, GDDR5, Hynix H5GQ2H24AFR
  4096 MB, GDDR5, Hynix H5GC2H24BFR

The rest of the BIOS appears to be majority the same thing.

hey guys. I have two 290 TRI-X cards with that bios version 015.043.000.001 , I did see no improvement in benchmarks (just 1 or 2 fps more) compared to the 280x toxic I had to RMA.
Did any of you downgraded to the older version of the bios?
I'm able to get 940khs in one of the cards that can  hold the memclock of 1500mhz and core of 1020.
But the Other card, (shipped same day and very close serial numbers, so they were made at the same time) can only achive 850khs because drivers crash if I push it to anything above 968mhz clock and 1300mhz memory.
Can 't get to try the Stilt new drivers as it seems most folks with this latest model or bios version can 't handle it and have crashed in windows.
I was thinking maby downgrading to the previous driver that
Handles this Hynix memory , and then flash it for the ones that Stilt made to save power consumption.
What do you think?

Well after much search and reading I finaly had the courage to flash my 015.043.000.001.000000 to the older one VER015.042.000.000.000000 but had instant crash entering windows, blue screen.
Also gave a try to the tweaked low voltage Stilt one 's and it boots to win but keep getting driver errors even after a clean re-install of the 13.12 drivers.

Tho I observed something strange, one of them had a difference when using hawaii info, RA1: F8010005
(this card have a more orange color in the cooler)  , the other one have memory RA1: FA000005 ( yelowish color in the cooler). They are only five numbers appart in the serial number on the back of them so how can they have different memory numbers and colors?

By the way the one that have the RA1: FA0000005 can mine at 1040mhz core clock and 1500mhz memory but the other one RA1: F8010005 can only do 965mhz core clock and 1250 memory clock.

Like BlockChasers suggested, getting a 50mv up on trixx on the card that performs worst managed to get her to the 1020clock 1500mem with no issues but the temperature is much higher (about 6 degrees), can 't deal with that.
Any suggestions? An explanation why two cards the same model buyed in the same day came with different RA1?
What's the RA1 on yours?

Are you flashed 290 or 290x GPU to old 290x bios??

[Equate]

Just flash your bios to old one which you already have and there will be no crash then.

So, Maybe we can test BIOS from another brand (ASUS, XFX and so on) with same vRAM??
