1425/2250 clocks, 50C

Right now, I'm using stak-amd, and with 2 threads, 1024x7. Around 810H/s

Currently using 4.4G memory.

I've tried to get more memory utilization, tried 3 threads 768x7. Hash speed doesn't improve.

Anyone have better settings? Claymore?

810 H/s mining Monero!! I could never get mt RX 480's higher than 745 H/s.

how much power draw atw?
for rx580, 810 sol per card is good.

i have a rig with 3 vega56, run stak-amd and got 5700 sol for 3 cards, draw 530w atw.

Did my first BIOS mod today,

Card is Gigabyte RX480 8GB Samsung ram.
I used the new Polaris editor 1.6 , One Click performance mod for dummy (me).
Flashed the ATI RX480 card bios.

Using xmr-stak-amd on Ubuntu 16.0.4
{ "index" : 0, "intensity" : 1024, "worksize" : 4, "affine_to_cpu" : false },

hashrate jumped 60x H/s stock to 816 H/s

I hosted the ATI RX480 using a Asrock x99 with E5-4655 v3 CPU ( xmr-stak-cpu 600 H/s)
Combined xmr-stak-amd 816 H/s + 600 H/s = 1416 H/s using 262 watt.

I flashed the bios at 9:30am , then I spent / wasted the next 4 hours trying to improve the OC mod.
But I only made the hashrate worse.
Back to the One Click performance BIOS mod, good thing that I was able to get the RX480 mining at 816 H/s again.

After the BIOS mod, it is profitable to mine XMR once again.

3 more ATI cards to experiment and make more mistakes.

840H/s is about the MAX I've seen on a 580. That was with 2 workers running. Couldn't do that on the 480's for some reason. Much better luck with the 8G cards, maybe because the workload is spread over 4 chips? I do have one stock Radeon 480 that is a beast and gets near 800, no backplate.
