RX 480/470/460 Owners Club

[AlienIsGOD]

will add you Ungari in a little bit

 

[AlienIsGOD]

The 6850 isn't enough so I picked up a xfx 6950 DD for $50. This should tide me over til my 480 comes back

 

[Tallencor]

Well now. Not to hijack this thread but interesting bit of info. Seems Win 8.1 and 10 limit dx9 to 4064 of usable Vram. Win 7 is not limited. Time to dual boot so I can use this card for it's original purpose. (Benching old modded Skyrim v.s. new Skyrim 64 bit.) Ffs.

I've got the Sapphire RX 480 Nitro+ 4GB card and it is very nice, I haven't pushed the limit on the card yet but I've got it dead stable at 1340MHz core and 1850MHz Mem

Just bought Sapphire Nitro+ RX 470 8GB yesterday, guess that's make me the first RX 470 owner in this thread I played around with undervolting last night with 1300MHz clock but undervolted to 1037mV with stock 2000MHz memory but undervolt to 900mV. Today I'm testing overclocking, currently at 1360MHz at 1100mV (stock is 1260MHz 1137mV) and stock memory speed. Wattman memory overclock only allows 2100MHz which is lame so I leave it at stock, it is RX 480 8GB memory speed after all. It is stable at 2100MHz and I expect it to be stable at higher clock.

Just ordered this myself, together with a new monitor: just over 650€, total.

No plans for any sort of overclock: quite the contrary, actually.

You bought a 4GB card with a 4K Monitor?

 

[HTC]

Yes. No need for all eye candy: "med candy" is quite sufficient, specially @ this resolution.

EDIT

And it's huge HUGE step up from 7850 APU ...

I simply cannot understand why you wouldn't pay a little extra and go the full 8GB VRAM when you could use every fps you can squeeze at that resolution. But the main thing is that Polaris is really not made for 4K displays, but does just get by at 1440p and UW.

I'm considering buying another Nitro+ for Crossfire before I make the step to 1440p, but wouldn't even dream of 4K even at that level.

Over here, it's not a "little extra", and i'm not really interested in the high details anyway. You seem to believe you need the best possible details to use this card or it's simply "no good", but i'm saying i don't even need half details and, as such, this card will more then suffice, and for quite a while too.

Until recently, i was playing Diablo 3 @ 1600 / 900 full screen on lowest possible quality.

I was actually planning on getting a 460 2 GB but then i saw a chance to get this monitor in what i considered to be a very good deal so i went with a "more muscle" card instead. Barring any malfunction, this card and monitor will last me 5 years minimum.

At least you didn't commit that fail!

 

[HTC]

For my current monitor, it wouldn't have been a fail: it would have been a massive upgrade over my current APU 7850.

So I finally got a chance to get a proper look at the RX 480 Red Devil PCB. I now understand why Powercolor said not to run Furmark on the card when using the high power BIOS. The Red Devil uses NTMFS4C10N MOSFETs instead of the MDU1514s found on the reference card. At 80C case Temperature(temperature on the surface of the MOSFET) the MDU1514 can handle a continuous current of ~50A. The NTMFS4C10N on the other hand can only handle 34A at the same temperature. Basically if you run Furmark on the Red Devil with a high power BIOS you run the risk of the high side FETs burning out. Lovely.

 

[Kanan]

Furmark is outdated/obsolete anyway, I don't know why people still talk about it, habits probably. Even when people didn't know it was a bad idea, 10 years ago I didn't use it, because I simply knew it's a bad idea to stress a GPU extremely, rather test with some games/3D Mark, back then and now.

So what you are saying is that the Red Devil custom PCB has inferior components to the Reference card?

 

[buildzoid]

Yep. Not bad enough to be concerning if you just want a basic 24/7 overclock for gaming. But for anything super intensive including really high clocks voltages and power limits the VRM is inadequate.

Just Why.

It's very surprising for a reputable 3rd party card have those as VRM. I read that you will do PCB analysis on Sapphire Nitro next, can't wait for that

 

[Kanan]

Those vrms are easily enough for 99.9% of users anyway. Amd overdid it with their reference design, maybe they wanted it to stand out as a overclocker watercooler card or they simply wasted money, I tend to believe it's the latter. I guess they wanted to play it 100% sure, powercolor is more like playing it 98% sure.
Of the custom models the devil is one of the best, only the gigabyte is crap - it's hot, cheap designed and doesn't really overclock.

Watch this:

1460mhz with water block on ref rx 480, i bet you guys like that:

Watch this:

On his podcast, Jay says he will be doing a video on how AIBs like Gigabyte are building high quality components for the 1060, but cheaper lower spec parts for the 480, even though both cards are named G1 GAMING.

 

[Kanan]

I told everyone to stay away from gigabyte products for weeks now, now you see why. I always said it's a wannabe premium brand.
The problem with building a cheaper 480 than 1060 is the 480 is a higher spec card that simply needs more power. So theres absolutely no sense in doing that. I think 4 brands will never do that: sapphire, asus, powercolor and xfx. I'm not sure about Msi etc. The four are 3 amd only partners and 1 expensive premium brand that's why.

 

[Ungari]

Sapphire is using better quality chokes to reduce coil whine in this generation.

 

[Black Flag]

New overclocking stable settings. Just setting powertune to 30%, adjusting the voltage by 90mV and setting a custom fan profile. I'm delighted!

 

[Apocalypsee]

Thanks for posting that Black Flag, looks like the core clock and voltage are pretty much the same on my low ASIC RX 470, so much for some say that RX 470 is a crippled crappy version of RX 480

I done some memory clock scaling using 3DMark Fire Strike. From stock 1650MHz on slowest RX 470, 1750MHz on RX 480 4GB, to 2000MHz and 2100MHz on two different core clock, one is 1260MHz and the other is 1400MHz. The card indded memory bandwidth starved, I bet that's the reason why there isn't much difference between RX 470 and RX 480
