RX 480 8GB Windows 8.1 - Crimson Edition 16.6.1 clocks 1300mhz - 2060mhz - temp max 72ºC 28.5 - 29.5 Mh/s on Ethminer
quite bad tho.. r9 290 at 1100 mas 30mh/s on claymore.. but at least temps are nice. lets hope next driver improves it:D
I dont see how you think this is bad the Rx 480 was never prediticted to be faster than a 390x or nano or 290 in pure mining power, those are high end cards the RX 480 is a budget part.
unlike those cards who need around 200-300 watts to make 28+ mhs though the 480 does it at 150 watts max ( or lower possibly)
making it an awesome mining card.
Of course if you have cheap or free power and can't find those aforementioned cards cheaper that 200-250 you won't be buying 480,s but for most of the world the 480 and 470s will be the go to cards.
the 470 is even possibly even better probbaly around 24 mhs for 60-70 watts
trotol, thanks for the 380x specs. Quick question, what are your temps? I might give 880 & 1625 a try if I can keep my temps in the <60 range (it is high heat summer here). TIA</p>
temps are on the screenshot, it`s a bit hotter because of high (+40C) temp. of the air in the rig room + crossfire directly in the MoBo with no add. cooling

@Koody, can you post Hashrate during normal mining operation? @Logicaluserhas pointed out that these scores were obtained using the 1GB DAG which is not reflective of current mining setup.
work said: "Don't overclock the memory. 1300mem is in between two timing straps and will actually reduce performance. If you can, in fact, it's better to downclock memory to exactly 1125mhz for tighter timings.
I run my R9 290s at 1125mhz mem and 1100 or 1060mhz core.
Driver version is also important, some of the 16.x drivers give poor performance (I use 15.7.1 myself)."
I was running about 24 and when I changed to 1125mhz mem and 1060mhz core, I jumped to 29.8 stable.
@K1llerFly 290s have timings every 125mhz. Follow @SIRacer09 's advice and use 1125mhz for the memory speed. Honestly I can't believe you can get to 1275mhz on your core. That's pretty crazy. Your temp is low also (insanely low for that overclock), that leads me to believe your settings aren't saved. Also like SIRacer said you're on the wrong drivers. Use 15.12 and you should see a jump in mh/s

This may be stupid questions but I'm still more or less a newbie, so here they are
my setup in summary : Win x64 8.1 / Sapphire NITRO R9 380 4G D5 / 4G RAM / CPU Intel(R) Core(TM)2 Extreme CPU X9650 @ 3.00GHz / SSD HD with the AMD driver (from the AMD website) : radeon-crimson-15.12-win8.1-64bit and the Saphire TRIXX software to manage overclocking
I may get my hands on a R9 290 or R9 390, the R9 290 will not be a sapphire (probably XFX)
1/ how about mixing AMD R9 cards from different brands in 1 machine, I currently have a Sapphire NITRO R9 380 4G D5: - will that work, or will it be a potential for issues/conflicts? (I assume the AMD driver will be fine, but what about the software to manage the settings, like TRIXX...) - or is it better to stay with the same brand (but maybe different models) ? - is there a noticable difference between different brands? I sometimes read Sapphire would be one of the better brands
2/ looking at the GPU and memory clockspeeds here, I see a complete different memory clockspeed in TRIXX The values in TRIXX currently are : GPU clock 1175Mhz, GPU Voltage +0mV, Memory clock 5900Mhz(?!) would tweaking the above values improve the below results noticably?
I'm still using Claymore miner (4.4 Beta) for dual mining, current performance : ETH : 20 a 21Mh/S DCR : 310 a 319 Mh/s
3/ is there a better software tool for R9 AMD cards in stead of TRIXX to manage the different clock speeds and voltages?

What you think about it ? I'm kinda new to Ethereum mining, but thinking about making a 280 / 290 x6 rig

Why?
an information please, where did u find that value ? how can I find that value for an r9 270x card ?

Lowering the memory clock has negligible effect on mining speed, it's mainly done to not use as much energy, better temps etc.

@davecoin raise your mem clock to around 2200 and also lower mem core by 50 or so you should see better temps and numbers
