@KainXS
Did you increase the Power Limit with the Undervolt?
What was your increase in clock speed?

Mystery solved!!

EDIT: bios codes are W80 for performance, and W91 for Stealth.

The fact that they both have the same BIOS revision irritates me, how are we suppose to easily know what BIOS a card is using if they all have the same revision number while not being the same.

The old card with Hynix memory could only hit 1810Mhz on the memory(from 1750) and the new card has Samsung memory and I stopped testing it at 2090Mhz(might go higher).

You should physically look at what's marked on the VRAM chips. They might actually be rated at 2000MHz and if it's the case they're good for 2250MHz.

 

[Ungari]

Okay. I have tested and can confirm. The XFX card ships with performance BIOS on both modes. I flashed STEALTH on the forward position, and PERFORMANCE on the "closer to power plug" position. The only difference is fan curves. Clocks remain the same.

See albums.

This fact alone shows that the card wasn't setup correctly, there should have been both Stealth and Performance loaded.
I would definitely RMA as this error was missed by QC, and who knows what else could be wrong.
I always buy from Newegg as they cross-ship my RMA for faster delivery.

Add me in as a RX 480 owner.

Default out of box BIOS switch setting. (towards the PCIe power connector.)

Edit: The way XFX word the Performance or Silence for the Dual-BIOS feature makes me think the default position out of the box is the silent BIOS. Move the BIOS switch to the left for the Performance BIOS? Hmmm

This is what you and @AntDeek should be testing, because your BIOS version is the same as BOTH of his switch settings. We still do not know what the settings were for AntDeek's card.
The image you posted showed the card was not under load, and so the clock speed was less than the stock Reference Card Boost, and so does not prove anything.
Also, what is the model number of your card?

 

[biffzinker]

I've tried flipping the switch both ways, card is behaving the same way to me.

To the right.

To the left.

Fan curve, and temperature threshold is the same in Wattman.

 

[AntDeek]

Exactly. XFX is sending out these cards with the performance option on both bios settings. I confirmed this. If you run ATIFLASH.EXE you will see that the bios they sent on both settings are the "W80" performance bios build, and not the "W91" stealth bios from their site. That's why they say dual bios compatible, because they leave it up to you to easily flash their stealth bios.

Also, the stealth option is just a fan curve and nothing clock related.

 

[biffzinker]

It's in my System Specs. RX-480P8LFB6

 

[AntDeek]

Same card as me with a different SKU, its still the XXX edition and uses the same bios. I would not recommend the stealth bios, as the performance fan curves are low as it is and act better when stepped up.

 

[Ungari]

I'd RMA these cards and pay the small difference to upgrade to a GTR, you'll be glad you did.
The GTR is being reported as having superior binning with ASIC.

 

[AntDeek]

To be completely honest I did I lot of research on it and it looks like it's only a 5-10% difference before an OC. After an OC it remains equal. The GTR is pretty much a plus of around 10% and I don't think I'd see a difference. As long as your card has Samsung memory it should be fine. My monitor is capped at 60hz so it doesn't matter anyways as v-sync is always on

 

[biffzinker]

Not having much luck overclocking the Samsung GDDR5 on my RX 480. The best I can get it up to is 2150 maybe 2175 MHz. The GPU almost wants to run @ 1400 MHz but it wasn't stable so I've been working down.
Hopefully 1390 MHz is stable, going back to checking stability.

 

[AntDeek]

Hmm. I get 2150 at 1410 just fine. I have a second RMA card coming Wednesday so I'll see how that one clocks and keep it lol

 

[AntDeek]

Also thanks Ungari for the RMA idea. I will do a full write up for a sticky after testing a third card

Just out of curiosity, what is the ASIC of this card?
Not that ASIC quality is the end all for OC ability, but that some have reported better results on high ASIC cards.

My understanding is that the GTR has a much more substantial heatsink and a different PCB.
That 10% difference you mentioned, does that refer to factory OC?

 

[AntDeek]

I believe the GTR is the same board just bigger heatsink, not that this cards heatsink is tiny anyway. My ASIC is 80.8%.

It is a different PCB. The GTR has basically a 390x pcb with a 480 GPU on it. They are 2-3" longer.

 

[AntDeek]

Interesting. Well I'm happy with my 80 asic tbh lol

 

[Ungari]

Since the default fan LEDs are White and would coordinate with my White/Black build, I'm tempted to get a GTR for Crossfire, but that would probably look bad especially if the cards were not the same dimensions.
I must say that the GTR heatsink looks impressive:

The Sintered Layered Microdonts?

 

[cdawall]

It's just a 290/390 heatsink on gpu that consumes half the power.

But what about the Sintered Layered Microdonts?

 

[AntDeek]

But what about the Sintered Layered Microdonts?

That make it so the confabulation can be smoother when hydroxalating during an overclock.

But what about the Sintered Layered Microdonts?

As far as I know XFX has been using that for a couple generations of coolers not.

 

[AntDeek]

Well, since I have another XFX card on the way for testing, I flashed my current one with the GTR (W81) BIOS. Will test and see. Everything looks good so far.

 

[AntDeek]

Immediate results. Power limit now goes to 50% for me!! hello more OC!!
