Haha, no one mention that when OCing. rolleyes.gif
So much thanks to both of you! What software do you use to see the memory errors? I was thinking that Sapphire use some better binned 8Ghz chips in the 480, but it seems that it's just the same chips with only a bios limitation for the 470.

HWiNFO will show you that if you start to OC and accumulate constant memory errors while gaming it's too much OC.-
1 (yes 1 in the count no 100) random memory error when playing it's normal, that's because have the hash to recover that usually to fix programming mistakes.-

A good game to detect memory errors in gaming it's: "Metro Last Light Redux" you can get it cracked by the way - And check there - Usually you will have memory errors in loading screens and that type of places but it's normal.-
The problem start when you are playing and have a constant generation of memory errors - In that case reduce the memory clock 10 hz and check again - Until you have no constant memory errors.-

In practice the RX 480 you can get 2130 / 2150 of mem freq

And another good recommendation for the RX 480 it's first overclock your core and then finally the memory because the memory errors and max freq are associated with the GPU core and voltage, so first get the best GPU Core that's will give you the best boost, and finally try to improve the memory that will give you a little boost more, and no errors.-

Finally if you in a future going to do a CrossFireX - Check the new card with the same clock and voltage individual, if pass the test - Put it in the CrossFireX and check again, usually with the CrossFireX you will need a few mV more of GPU Voltage and less memory clock - Because in CrossFireX the administration of memory it's different and more sensible to errors - Example my video cards in single can get 2155 of Mem Clock but in CrossFireX 2135 mhz without errors.-

I edit this text 100 times my english it's crap biggrin.gif

The 480 is 20% more expensive than the 470, so I think that the 470 is the way to go (Isn't the 470 getting better core clocks generally than the 480?). I will be playing at 1440p, so don't you think that I have to start with memory?
Also, anyone know of the limitation in the 470 memory clocks? Some sites say 2050, others 2100...

depends on the model and memory chips it has, if it is the higher clock chips then it should hit 2k speeds but its not a promise.

I talk about the 8GB Nitro+, the one with 2000Mhz memory. I read that the software only let set the memory clock at 2050Mhz max and others say that the software let them to put the memories at 2100Mhz, so that's what I'm asking, what's the max possible to set in software. I know that it can just stay in 2000Mhz if I'm unlucky, but I ask about the max allowed to set to the memory, not if the memory will be able to run at that speeds.

YES!!! Finally the MSI Afterburner Beta 14 with support for the RX 480

http://www.guru3d.com/files-details/msi-afterburner-beta-download.html




No more problems with the voltage of Wattman you can left that **** default and MSI will do everything, have RivaTuner build in, can disable ULPS with the same MSI, enable extended voltage, overclock and all that stuff - A very niceee fan curve - Now more happy than anytime - Very secure overclock in every startup and not a lotery thinking if wattman change somethiing.-

If you are going to put the values of GPU Tweak II be sure all in Wattman it's in default (press in default in Wattman) and the percent of the gpu voltage have another scale so check it with gpu z in full load, example in GPU Tweak II was 81% here its 24% but its the same.-

And RivaTuner Stadistics check the FPS in DX12 well in tomb raider the only game dx 12 I have make a crash but its a good starting point

GREAT!

Closer to 1900Mhz for RX 470, actually.

Memory bandwidth is the primary differentiator in performance other than stock frequency between the RX 470 and RX 480.

10GHz memory on an RX 470 would beat the best RX 480.

After ~1.15GHz memory overclocks have a larger impact than GPU overclocks... depending on the game/benchmark.

So in practice if you can get more than 2100 mhz you have a good performance.-

I was talking abot the 2000Mhz 470, the 8GB Nitro. But yeah, at 1440p I have to start with the memory. I have now a 470 Nitro+ 4GB version, but I will change it for a 8GB soon. Tomorrow I will try it, but 1900Mhz seems unlikely without memory errors.

As far as I can see, the 470 8Ghz only can go up at 2100Mhz, the 2050Mhz limit is in the first drivers. As the 480 tops at 2130-2150, it should be doable to get the 2100Mhz out of the 470, hopufully without memory errors. And only a 2% OC in the 480 over the 470 is not worth. Aside from that, at equal clock speeds, the 480 is about 3% better (2,3,4% better the most games).
