RX 480/470/460 Owners Club

That is the card my brother has. He gets about the same clocks (1410/2250)

have you just toyed with the memory on its own to see how far she goes?

I'm able to push the memory quite high alone but once I hit a certain point the numbers stop climbing.

Now start adding some core clocks to it and it gets real interesting..

2250 all the things

Sapphire Ed told me that after a certain point the OC number drops precipitously under load making limiting the fps gain.
Has anyone saved stats while gaming showing a steady clock-rate under load?

 

[cdawall]

1430 is the max I can keep dead solid stable through games with my pair.

Hey guys. Hope everyone is having a good Xmas Eve so far and a good Xmas tomorrow.

I have done some testing, and as per XFX's website, my card is "dual BIOS capable". I have tested and found that the factory sends the "Performance" bios on both chips, and you can flash the "stealth" bios to another switch position.

1410 and 2150 seem to be the highest I can go without harming performance, but I will test and get back to you guys.

Can you show me on the website where it says that?
Shipping the same profile on both BIOS chips makes no sense at all!
You should call them like I said and ask.

Cannot get the embedded image to work, so I uploaded it.

The way I read this is that you get Stealth or Performance depending on which you select with the switch, which makes sense.
I do recall that you said you manually OC'd the card with the switch moved towards the I/O plate. If that's the case, then you probably made changes to the Stealth BIOS, and not the Performance one.
I also recall you stating that you could not tell the difference between either setting which is unusual since there is a different Fan Profile for each.

Question; When you OC to achieve that 1410Mhz, is this at stock voltage?

 

[AntDeek]

So the definitive answer, this is my first AMD card after years of GeForce.

How the hack do I tell if this card has a dummy switch, or two bios(s)? LOL

The Fan Curve and Boost Clocks under load should tell you if the BIOS Switch is working.
However, since there is only a 22Mhz difference between the two profiles, I'd look at the Fan speeds as the Stealth is supposed to be very quiet with a much lower fan curve.
Use the software to view the fan curve using each BIOS.

 

[AntDeek]

So using Wattman at all defaults the fan numbers should be different in each position?

You could open GPU-Z and look at the BIOS version then flip the switch and look again. It shouldn't be the same BIOS version.

 

[AntDeek]

Regardless of the position the GPUZ bios shows the same string. And Wattman shows the same 1330 min 3000 target for the fan curve.

Did you flip the switch while in Windows? If you did reboot.
If you already rebooted, it means both BIOSes are the same.

 

[AntDeek]

Flipped the switch, and the rebooted. So looks like this card has a dummy switch

Also, a small issue that I never had on an NVidia card. Upon wake from sleep, windows 10 will see a second monitor that doesn't exist, and make this "monitor one" leaving me unable to use monitor the actual single monitor I plugged in. My actual physical monitor is recognized as monitor 2, while the "monitor one" is on "Microsoft basic display adaptor."

 

[AntDeek]

?

yes, I let voltage remain auto.

If your card does not have a working Dual BIOS, I'd RMA.
A Dual BIOS is the most important feature of that card as it is protection in case of failure.
If you purchased from a site like Newegg, they can simply send you another new card without having to go through refurbishment.

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.

Mystery solved!!

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

The clocks should not be the same, should they?

 

[AntDeek]

Well technically XFX never says anything about speed just fan noise perhaps the card will purposely throttle under stealth

What I am saying is that typically a quiet BIOS profile is at the stock clock speed of 1266Mhz with no factory OC whatsoever.

 

[AntDeek]

I guess it's such a mild OC that it doesn't matter

Had to RMA my 4Gb RX 480 Gaming becasue it kept having power/crashing issues. 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). The core clock also hit 1400Mhz on stock volts which was better than the old one which needed 1.2V+ to hit that.

So I just set the card at 1303/2000 and undervolted it and called it a day.
