starting to have 2nd thoughts about all this mining thing. perhaps its not for me..
just got my 2nd sapphire rx 480 8gb ref card and flashed it with the 32mh.s bios. which gives me 31.4 or so.. unlike the other identical card which doesnt give more than 28.5 using the exact same bios. problem now is that after some time the mh/s of this  31.4mh/s card drops to 0 and i get an OpenCL error, then the pc hangs and nothing works.

can some1 recommend me of a good card/brand with more consistent results that doesnt require so much annoying time waste?

I advise against putting roms that you download.

Try to find your personal setting because each card is different.

Here are my settings:

hello i have buyed 2 power color red devil rx480 8gb and i updated whit unlocked bios downloaded from official devil's forum... i'm mining whit claymore 7.4 but i have only near 24.8 Mhs for each card... any setting mod for this card? thanks for help me

This is what I'm using for my two Red Devil 8GB RX480.

http://www.filedropper.com/powermod

This will set clocks to 1150/2150. You may find that 2200 is stable for the memory too. This is based off stock ROM, not the high power one.

I'm using Claymore 7.3, doubt that'll make much difference. I also use the very latest Catalyst drivers, so 16.11.4 here. Make sure your Virtual Memory is set to 16GB+

I use MSI Afterburner to change the clock speeds more.

after some more testing it seems that when the sappgire ref cards get too hot the MH/s drops from around 31.5 or 30 (depends on card) to around 27-22MH/s and keeps on throttelling and jumping all around the place.

since now its winter here in germany, this isnt such a big problem for me, but i plan to take the rig with me to a much hotter country in the summer and im afraid this will be far from ideal setup.

also im currently using some XFX rx 480 8gb RS, where i just copied a memory strap. they seem to run stable at 28mh/s even when the sapphire cards start to throttle. so i believe they will be the right choise for me for the long run. also im about to get one sapphire NITRO+  480 8gb card and try to flash and OC it like some guy on youtube did to get like 30.5 MH/s.

question is, any of you guys are living in hot climate regions or simply run your rig in a hot poorly ventilated place? i would be interested to know what you think about the optimal setup for such places Roll Eyes

GPU cards don't work well  to the max capacity when they are heated up. How about adding some additional fans or something for good air flow. Just make sure there is good space between your cards and also good ventilation for airflow. And yes, it would be awesome if some guys come up with something solid.

You can just download the Polaris BIOS editor and copy the lower memory strap to the higher frequencies.

Do you have a working link for a BIOS version for the XFX RX 480 8GB?

I already tried Boysie's RX480 BIOS, but it's not giving me more hashing power.

I am mining with the Zcash Claymore v8.0.

Unfortunately, the link on the start page (as stated from several other ones before) is broken: https://bitcointalk.org/index.php?topic=1584617.980

Thanks. Kind regards
