I havent checked the card yet. im in the process of changing my loop. redface.gif
I will take som pictures to see soon.

Thank you

Hello Again. I haven`t got the time to test this before now too munch work. But i will maybe flash this weekend.

1 : But whats the best bios for my cards ? I will overclock a little.. but nothing munch i think just experiencing it.








As you can see i run Crossfire 2 R 290 X (sapphire) whit full EK Block..
As you can see on the pictures the are SKHynix memory..
The cards will be cleaned whit Isopropanol Before new goop is on.
My card never been over 43 Degrees hot. (in my Ek Loop).

Question 2 : How long will the flash take ? Minutes ? will there bee some Tweaking later ?

Question 3 : Its recommended to flash in dos i presume ?

Is there any Step by step guide ? Cheers Håkon! thumb.gif

1 - There's no best bios ready for your cards.
You have to figure out yourself with a lot of testing (especially since you have 2 cards).
Some bios won't work as expected because of memory timings that are too tight or because of power states with too low voltages (crashes, black screens etc...).

2 - The flash itself takes a few seconds at most. The best thing you can do is modding your bioses with Hawaii Bios Reader and check what works best for your cards (especially since they're watercooled).

3 - Yes you should absolutely flash in dos.

Here's a tutorial for Atiflash:

Thank you for good answers.. i hope i get some preformance gains whit this biggrin.gif

And my cards ar not in the computer now.. i took them out to check them.
So i will flash one by one.

Is There a Safe "Bios"

Every card is different, so feel free to try bioses. As long as they're compatible with your PCB (and your cards can handle the overclocks if available), it should be safe (won't destroy your cards. If something gets wrong, boot on the second bios and flash back the faulty one with a working bios).

Performance gains are abysmal and quite useless except if you're into benchmarks.

You should try to find out what overclocks your cards can handle and then edit your bioses with your updated clocks/voltages using Hawaii Bios Reader (there's a lengthy thread about it here). Then you can get rid of overclocking software.

Then you can maximize the efficiency by finding out what lowest voltages the p-states can handle.

I got a R9 290X 4gb with an EK block like yours. My card is not the best overclocker. After a lot of trial and error, I ended up with its default bios (you can dump yours in GPU-Z) at 1150/1400mhz@1362mv and edited the memory timings with the Stilt's ones. Could go lower on the voltage but it would produce artifacts in my recorded videos.

Modded 390X bioses get my card cooler but they tend to be less stable (in my case, I get black screens when connected to displayport in some games). Those MLU bioses would crash it too.

I'd say that ~1100mhz is the wall where it starts requiring huge voltages for a few more mhz. Goodbye efficiency (and good luck with the heat especially since you own 2 cards lol).

When it comes to the memory, going above 1375-1400mhz on Hawaii GPUs is usually useless, especially when it starts producing GPU memory errors that can result in performance drops (Even if you're stable in games, you can check those errors in HWinfo64).

Thank you for an good answer. (sorry later replay ive been at workout)

I think i will not do this. Basically it to mutch work and to little to fix.
Ill keep them as they are and try some overclocking as they are. (My ek water cooling is quite good)

Sorry to ask this noob question, but I wanted to be sure:
1-if I flash the very first bios in the 1st post:
25M.bin = -25mV offset, 1000MHz / 1250MHz (engine / memory)

the -25mv means that with this bios the card will run undervolted by -25mv for every state?


2-has anyone by chance modified the bios above to push the undervolting even further (so with -37.5mv or -50mv)?If yes would you please share it?

Sorry for necro'ing the thread but I've come across a weird issue.



I have a R9 290 Tri-X OC (original edition), which is a reference 290 (this one uses Hynix AFR) with a decent aftermarket cooler out of the box. These MLU BIOSes would work just fine on my 2500k + Sabertooth P67 rig.

I've upgraded to a R7 1700 + C6H, yet if I try to flash any of these, the machine POSTs but the VGA boot led stays on, and I get no video output + one long beep and three short beeps which indicate a problem with the video card. The only way I can get it to work on this machine is to flash the stock, original BIOS.


Is there some BIOS validation going on in this platform that didn't happen in what is a comparatively ancient platform like Sandy+P67? It is weird because these are signed IIRC and shouldn't cause any issues.


Any ideas?

I'll try modding the stock BIOS with HBR next and see if it boots. Meanwhile I've asked Sapphire for the latest UEFI and non UEFI BIOS for my card, just in case.



edit: it boots a modded stock BIOS. Oh well, it looks like the crosshair doesn't like the MLU builds or doesn't like a 290X BIOS on a 290.

Sounds like it might be the device ID issue between 290x and 290.
Needs a tiny edit in a hex editor, see below.

Thanks!! I wasn't aware of this being an issue.. well, never had a related problem my old P67 rig.


Took the modded MLU BIOS I was using, changed device ID from 67B0 (290x) to 67B1 (290), saved the file, opened and saved it with HBR to fix the checksum, flashed it.. and it booted without issue, just like it did these past few years.


Thanks again! I can fully enjoy my 290 again thumb.gif
