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.

Thanks this evening i try this Rom ... how many mhs have you whit this rom? Thanks

29.7 @ 1150/2150 and 30.1 @ 1125/2200

Every time a block is mined, a certain amount of BTC (called the subsidy) is created out of thin air and given to the miner. The subsidy halves every four years and will reach 0 in about 130 years.

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

Hello everyone ,

I want to know if it is normal that the gpu does small drop of charge?

It is not 100% constant, one sees well on the gpuz.

Do you have the same problem?

My hash rate is 31.2 on average and sometimes it drops, see screenshot.

you have an idea?

The new AMD drivers - Crimsom Relive edition 16.12.1 use driver signature verification and I also noticed performance dropping.
Instead of running bcdedit and disabling integrity checks/signatures, I rolled back to 16.9.2.

Now hashing ~29.246 mh/s on my rx 480 reference cards using claymore's version & the ultra low power rom.
Will have to retest with Genoil.

I also upgraded the rx 480 from 4gb to to 8gb because you can with nearly 100% of the initial 4gb reference 480 cards.   Smiley
Temps 80-84C.   Fan speed 66 - 75%.  They will throttle the gpu if they hit 90C.


EDIT:  Interesting to note I get~22-23 mh/s in genoil 1.1.17 now, but in Claymore -mode 1 its about 29 mh/s
Hashrate in genoil has gone down  by about 2 mh/s.

Very interesting.

Hello,

I am desperately trying to increase the hash rate of my XFX RX 480 (RX-480M8BFA6), but no matter which Bios I try, none is better than the stock bios.

In fact, every bios results in a lower hash rate than the stock bios.

Stock: 21 MHs (which is not much either)
Other ones: 8 - 18 MHs

Also in specific, with the 480LowEnergyOK.rom I only get 8 MHs. Some of the ROMs I also tried (but none gave me a higher hash rate than 18 MHs):

Several from Anorack (memshift, overclock)
low-pwr-29MH-Boysie.rom
3x3LowPwr.rom
WIN-RX480-31.25-Boysie_v2.rom

I also tried copying the 1750MHz strap to the 2000MHz strap of my stock bios, but that let's my computer crash.

Do you have any idea what could be the reason that no other ROM gives me a higher hash rate?

Thanks very much. Kind regards
