That's not really true, running them that hot hurts efficiency on air and can have dramatic effects on stability. Just because they can be ran at ridiculous temperatures doesn't mean you should, or that the card wouldn't benefit from better temps all around.

Thanks to you

I can do gaming + mining in 1 rig..

mining starts when I walk away from the PC. (work, sleep)

mining stops when I start playing games

hehehe

Was fortunate enough to snag one of these guys from my local Micro Center last night.  Was doing my daily check of all major retailers and it popped up they had one lonely card, but no option to put a reservation on it....Hopped in my car and sped excessively the 30 mile span to get the card   :wheee:

 

RX 480 - Yay! (Click to show)

 

 

GPU-Z Validation

 

https://www.techpowerup.com/gpuz/details/kwhpf

 

It appears to be a halfway decent :sonic: so far.  I didn't have to alter voltage at all, boosted power to +50%, forced fan to ~3k RPMs and I have a solidly stable 1350/2250 in Time Spy; haven't tested anything else yet.

 

 

RX 480 Stock Time Spy

 

http://www.3dmark.com/3dm/13337861?

 

 

RX 480 1350/2000 Time Spy

 

http://www.3dmark.com/3dm/13336144?

 

Sorry no screenshot of this one

 

RX 480 1350/2250 Time Spy

 

http://www.3dmark.com/3dm/13337673?

 

 

 

 

So we've got an 11% graphics score boost from increasing power and a small overclock.

 

Another 2.9%, for a total of 13.9%, graphics score boost from adding the memory OC in.

 

I was able to get a nearly (couple points) identical score by using only 37% power boost...until the memory overclock came into play.  That requires 50% power to take full advantage of additional RAM speeds.  Changing memory voltage did not help at all...maybe it will once 3rd party tools are available and I can push the memory a little further.

 

I'm almost certain it can go further once cooling is improved as it nearly passes at numerous different clocks past 1350...stalls in the same spot about 75-80% through graphics test 2 anywhere between 1351-1375.  I have a feeling it will make at least 1400; if not more.

 


 

I will be stripping the factory cooler off quite quickly, but does anyone know if Sapphire actually voids warranty?  Their website says so:

 

  1. The limited warranty does not cover products that the user has disassembled. GPU or ASIC devices (VGA) are sensitive to thermal (heat) issues. The heat sink has been designed to meet the requirements to ensure reliability of the product. Any warranty is rendered invalid if the product has been dismantled or the heat sink has been removed as this may causes damage to the GPU or ASIC device. Non-compliance will cause the warranty of the product to be void and repair will be at the users cost.

If this is the case I will add the MC warranty so I don't have worry about it, and I can order the XSPC Blade GPU block when it comes out in a couple days :applaud:

 

I opened a ticket to have the information directly from them in writing anyhow.

 


 

I ran a couple quick Time Spy's on my main machine that is still rocking my awesome 290.  The PCs are near identical so I feel it serves as a good real world type comparison.

 

Z87 - Main Rig

4770K @ 4.5GHz

16GB DDR3 2400MHz

R9 290 Reference - Water Blocked

 

Z97 - HTPC

4790K @ 4.6GHz

16GB DDR3 2133MHz

RX 480 Reference - Stock Cooler

 

I have had issues pushing previous 3DMark max clocks in Time Spy.  I am capable of running the 290 around 1300/1700 for most of the old stuff.  I'm not sure if this is entirely due to the Beta 16.7.2 drivers I'm running, or the fact that Time Spy pushes the card that much harder than any of the old stuff...maybe a combination of both circumstances?

 

Currently the best I have to share for Time Spy is 1200/1500.  For the 290 that is a 26.7% core OC and 20% on the VRAM; 947/1250 stock.  The 290 obviously has a better case scenario since it doesn't suffer from throttling, but this is realistic as essentially no one is running a 290(X) with the factory cooling any longer.

 

R9 290 Stock 947/1250

 

http://www.3dmark.com/3dm/13339313?

 

R9 290 OC 1200/1500

 

http://www.3dmark.com/3dm/13339426?

 


 

This is where things get a little interesting...

 

At stock clocks even though the RX 480 is throttling due to power constraints it still outruns the 290 by 8.6% - 3551 ~vs~ 3857 graphics scores.

 

*EDIT* RX 480 Stock Clocks 50% Power - No Throttle (Click to show)

*EDIT* Had a Derp moment of clarity and thought I should run the RX 480 without power throttling at stock clocks *EDIT*

 

Once the RX 480 isn't power throttling at stock it then outruns the 290 by 14.1% - 3551 ~vs~ 4053 graphics scores.  http://www.3dmark.com/3dm/13353663?

 

Give the 290 some extra juice and turn up the frequency to turn the tables as it outpaces the RX 480 by 3% - 4415 ~vs~ 4284 graphics scores.

 

1200 core clock on Hawaii cards is fairly common if you crank the voltage/power up on them...I've owned/tweaked several of them and I'm fairly certain they all hit 1200 if not VERY close to that mark.  

This is an impressive showing for my RX 480 since it is limited in cooling and there will certainly be more power to go around once it's nice and chilly :Snorkle:  

 

Once the AIB cards are out these are going to be some badass little cards.  I remember paying $350 for my 7870 DC2 a couple years back...my how things have changed :specool:

I'm now testing the unlocked asus bios. 1400mhz@1162mv. Not bad! This card is a beast
post #57 of 4340
I finally checked my ASIC on my Sapphire RX480 8GB card. I was surprised how high it was. This is a RX480 that will actually run pegged at 1,400Mhz stable in games at 1.150v with a stock air cooler set on auto.


91.5% ASIC QUALITY


That seems really high. GPU-Z said it was higher than 99% of all other RX480's lol.

Im guessing this is why it runs at 1,400mhz stable 24/7 in games.

Do you guys think? Does the Asus unlocked bios help with overclocking? Can I increase power limiter higher? More voltage than 1.150?

Everyone post your ASIC quality! That would be cool to see what they are all like. I'm loving this RX480!

Damn pc, anyways. Thats the highest I have seen yet. Mine are 69 and 84. I did have an 81 which died and sent it back and got the 84 in return.

I saw on on ebay, XFX RX480 going for $275 with like 25+ bids and 3 days left, it was a 90.5% ASIC. That is what intrigued me to check mine, and I couldn't believe it was actually higher then the card on ebay.

Anyways, I am happy with it. I felt like I was achieving slightly higher overclocks than average guys online.
