Seems like copypasta to me.

It's written in the link and a hundred times in this thread, it's really not necessary to post that question. I admit I thought about posting it too but then I was like .... duh .... it's already written there.

Btw I wrote to XFX and here's the answer:


Dear XFX Team,

what are the dangers of flashing a R290X BIOS on a R290A card. I purchased an XFX 290A card and after reading about this possibility I flashed the R290X BIOS and was able to unlock the additional Shaders and ROPs.
Could you tell me whether I actually have an R290X card which was labelled as R290?
Why would this happen by the way?
Also, are there any risks? As far as I can tell, there aren't any because I am running an R290X card with a R290X BIOS.
Your help would be much appreciated.
Kind regards,


Hey , this seems to be the question of the week.
Here’s the short explanation.
1. Voids your XFX 2 year warranty.
2. You cannot Unlock the shaders, they are cut off by laser
3. The 290A’s were just failed versions of the 290x, Basically AMD tests every Hawaii GPU and if the GPU can take the 290x speeds, they Pass. If not, they get downclocked, lessened shaders, and tested again at 290A speeds.
Forcing a 290A to be a 290X works for about 2 weeks, some claim longer, but I don’t believe them. This month alone there are over 50 units permanently bricked that we’ve had to reject.
290A’s are not 290X’s, the flash will not stand and I won’t be able to help you.
Be safe.
Play Hard!


Might be a standard answer. I told him I unlocked the shaders and TMUs and he says they can't be unlocked.

While I don't believe much of what he says. Where does gpu-z etc read the shader info from, is it the bios? So if you flash a 290x bios and it takes, does that just tell gpu-z there are more shaders? My question is what if they really are cut off by laser or something and all you "unlockers" are just on a nice placebo effect and the only difference in performance is the slightly higher clock speed ?

I'd assume GPU-Z reads them directly from the cards internal chip thinggy? i have no idea... tongue.gif

I believe it's more than just higher displayed clock speeds, I got just over 5% increase in test results on Heaven and 3DMark.
Bizarrely enough his statement matches with @criticalhit card, which lost performance after 2 weeks

.. But I'm sharing anyway just in case there is some truth to xfx claims ... Mine was fine for a week or 2 until it lost stability with 290x bios but its still rock solid on 290 bios so I can't complain .. Just a little anxious to see if it remains stable here or also gets glitchy ...

sorry to hear that btw
were you OC ing hard before the card lost it's R290X ability? were there any signs before that happened?

I would assume it briefly tests the chip on startup and takes calculations for the other parameters.

I know that if you raise clock speed, then the GPixels and some other stats will raise also, same with memory and memory bandwidth speed.

GPU-Z does not read it form BIOS, I've been on a 290x BIOS since day 1 but because my card didn't unlock it tells me that I have 2560 cores.

The unlocked 290's are not laser cut, they are full blown 290x chips. The fact that they are designated 290x chips in the serial # on them proves that this XFX rep is lying. AMD would not be silly enough to mark the chip as a 290x before they tested it.

Anyone have a round

There are a couple of comparisons i've seen of R9 290 vs R9 290 unlocked with the same clockspeeds, and it does seem to work.

I havent tested mine because, well, I figure 3dmark is the most definite test.. and im not waiting a half hour for the stupid test to finish.

Okay that sounds right since the serial #'s are corresponding to 290x's (didn't know that) I did say a few pages back that I figured XFX was probably lying because they don't want people buying 290's and just unlocking them.

They way I figure it (and again something i've said already) is that some of these 290's that are locked are really 290x's that they just turned in to a 290 because they needed more 290's and some of them are 290x's that didn't make the cut (might be what critical hit has for example)

What I said a minute ago just occurred to me since I wasn't sure where gpu-z actually got the info from.


@criticalhit that sucks man, I guess as long as it stays stable @ 290 clocks you got what you paid for. If it becomes unstable I guess you can RMA it even though it might kind of be your fault. Not trying to be mean, just honest.

Maybe the rep doesnt know that there are actually cards shipping out with a core that claims to be a 290X, and instead thinks people are flashing legit 290's [2020 chips] and XFX is actually getting RMAs on bricked card? (Thru bad flash, or people getting black screen after flash)

All the complaints about people asking the question if they unlock is clogging the thread up just as much.
