The XFX cards only go up to 20% unless flashed with the (W81) GTR BIOS. Then it will take up to 50.

 

[AntDeek]

However your mileage may vary with the GTR bios. I have still some testing to do with it

 

[Ungari]

I would if I could. The slider is maxed out at 20%. Should I try flashing the GTR BIOS?

Having the Power Limit nerfed sounds like the Quiet Mode, are you using the Performance BIOS?

EDIT; Stealth BIOS, not Quiet Mode.

 

[biffzinker]

Yup, using the latest Performance BIOS. I even checked with ATIflash it said I had the exact same Performance BIOS flashed as included with the download. Doesn't matter I just flashed my card over to the GTR BIOS. Now I have the Power Limit bumped to 50%.

 

[AntDeek]

Ungrari, both Stealth and Performance has the same 20 limit. This is why I am currently running the GTR bios.

If all settings are default does the power limit even matter?

 

[AntDeek]

Update. GTR BIOS causing low FPS drops in Battlefield 1. Reverting to (W80) Performance.

Doesn't want to maintain the Boost clock for me. FPS wasn't down but the GPU was running under 1 GHz most of the time (600 MHz - 988 MHz occasional spike over and up to 1188 MHz.)

Edit: Driver crash resulting in a system lockup. As soon as Windows made it to the lockscreen fans jumped to 100% then back down. Fans sure can make a lot of noise.

 

[AntDeek]

Yeah. This is why I flashed back to W80 lol

Not sure what you mean by default settings, do you mean stock clocks?
The Power Limit matters greatly when manually overclocking, or undervolting.

I meant while running all stock settings.

Sounds like the GTR BIOS is too much juice for the VRM section and the card is nerfing itself?

Presumably. I don't know if you play BF1, but the yellow "lower FPS than ideal" indicator kept coming on.

 

[biffzinker]

VRM section and the card is nerfing itself?

Or the heatsink is unable to cope with heat coming off VRM plus the GPU.
The heatsink on the VRM is also main heatsink cooling the GPU. There's nothing on the memory chips for my card.

 

[fullinfusion]

Mine with factory Bios from MSI... I thought all the RX cards did +50 on the power limit

 

[AntDeek]

Okay. So here is the definitive XFX card info post. I have tested this with TWO cards, and info from you guys.
My second card I have here is an ASIC of 75%, so I will be returning this one and keeping my 80.8 ASIC.

XFX does, in fact, ship these cards with the same "Performance" BIOS in both positions of the switch. The preinstalled, and current bios is W80.

The "Stealth" BIOS, is the same as performance with a quieter fan curve. Its code is W91.

The GTR bios causes issues when flashed to a non GTR card. The GTR bios is W81.

These cards are locked to a 20% power limit increase, and the GTR has a limit of 50%.

Flashing a GTR BIOS can cause some weird issues. Do at your own risk.

It honestly makes more sense to skip the Stealth bios, and just adjust the fan curve on the pre-installed Performance (W80) BIOS.

 

[biffzinker]

A few voltage bumps to the GDDR5 gets the clock speed up at 2110 MHz for me. Left it looping, had to drop the GPU down to 1385 MHz.


ASIC quality for mine is 72.4%

 

[Athlonite]

New Sapphire Nitro+ RX480 8GB OC working nicely much better than the R9 285

 

[KainXS]

After checking some other user pics of the RS cards it seems that the GTR cards have much more different VRM setup. The GTR VRM's are rated for 325A@90C but the RS cards are only rated for 135A@80C.

That could be why the power limit is set to a max of +20%.

here are a reddit users pics of the PCB

i can once again edit OP gonna need names of new ppl so i can add them to the list

I picked up a 4Gb RX 480 Gaming X and I am currently running it @ 1303/2000

@buildzoid

Is 135A@80C really the rating for the RS? That put's it a good bit below the powercolor even

EDIT:

Screw redits image

So those are 4C10N's from on semiconductor or the same phases used for powercolors crap, but wait it gets worse there are only 4 phases for the GPU. That gives you 46A@25C and 34A@80C for a total of 184A @25C and 96A @80C

[KainXS]

asked @buildzoid on his youtube channel to take a look also to confirm it. Based on the pictures of though it looks like its using 4C10N high side mosfets(the same as the powercolor Red Devil) with a 4 phase design.

I'm actually hoping I'm wrong to be honest.

thanks for uploading the high quality picks cdwall

Yep it is now settled 4, 4C10N's design is very close to a 460 as opposed to a 480...

You don't mind if I use your photos for a video right?

I recently upgraded my VRM rating method partially because of this card since. If you use the continous drain rating of the high it would blow up instantly in theory which it doesn't IRL so that obviously isn't working.
With the new method and calculating for 500KHz the VRM should handle 104A at 125C. However the NCP81022 doesn't do 500KHz on 4 phases it does IIRC 440KHz at best and on the RS it should be running in the 300KHz range since that's the norm for all the RX 480s I've seen so far. At 300KHz it will handle quite a lot more power than that 104A even at 125C.

Also it's important to note that the phases in that VRM are very spread out with doubled up low side FETs so the VRM should run pretty cool.

Yes it is an even worse PCB than the RX 480 Red Devil which I called terrible. It should still handle an OC on under 1.2V(I'd expect the devil to handle upto 1.3V without too much hassle). I'd set the BIOS current limit to 140A.

Go right I ahead. If you want the original 5k photos as well let me know and don't hesitate to shoot me a pm if there are any other models you want high res photos of and I'll see what I can do.

 

[AlienIsGOD]

I have another card coming in the mail today. Will test, and do a full write-up here as the end all be all of the XFX cards.

Also, could you add me? AntDeek GPU 1410 and mem 2150. 80% ASIC.

I didn't know you had such a informative YT channel I sub'd and cant wait for more!
