RX 580 Nitro+ Special Edition (SE) mining help

[avalon44]

Hi, for those having issues with 27 Mh/s max on 580 Nitro+ 8GB SE (Samsung) maybe this will help. At least it did help me. The problem is the dual-memory types in such GPUs.

Getting my Rx 580 next month after a 1.5 month delay in delivery... Will see how it performs!

Hello friends,

I have RX 580 Nitro+ Special Edition, with 179.69 MH/s but almost 1.500w.

I have mod all bios

How to save more power?!

Any tips friends?

Regards

Drop Voltages and Clocks to save some juice :-)

875 1150
875 2050-2250 (depends on the Chips ya have ... and the mod ya have done ...)

Should get the 580 down to +- 85W GPU-Z

my rom 260 sol/s in zcash, 28 mhz in ETH/ETC. If you need, pm email for me, i sent you my rom.

No, i meant that you 1st adjust and tweak the voltages the gpus need. A Bios change is the last step of a few - and not really needed.

It depends on: your miner (if there are options to adjust voltages/clocks), your OS (W10/Linux)

As Example on W10 you can use AMD Wattman (Part of the driver) to set profiles for every GPU and adjust there the clocks and voltages and you are set and no need to mod the Bios ...

Hello,

Thanks for your reply.

I have hynix memories.

You mean i must edit my rom and edit my voltage and clock?!

Thanks

Do you have the right drivers installed? I had a driver with a bug installed and could not get the card more than 26Mh/s.

Reove your driver with DDU and install the last AMD Blockchain driver. that did the trick with me. Have them now running at 32 Mh/s.

This card can mine > 30.5Mh/s depending on memory.
I have mod more than 20 and they are mining on HiveOS around 31.5.

Most of them have dual memory Samsung/Hynix. Samsung Timing from Ubermix is not really stable.

This Timing is stable for Samsung K4G80325FB on those GPU.

Did you ever make a ROM for your cards, and are they P/N 113-1E366CU-S5S ?
All the roms I find are for P/N 113-BE366EU-Z48

I just picked up 5 x Sapphire Nitro+ SE (Micron Memory)

All 5 of them hash at 29.6-30.5mhs in silent mode without touching the bios. Running Aug 23 blockchain driver.

My oc settings are:
Core: 1150
Memory: 2250
Core Undervolt: -96
Memory Undervolt: -96
Fans: 50-80%

All above is applied via command line to Claymore 10.2

This gives a power at the wall of 125w per card and 83w in GPUz

The cards have been running for 12hrs with no errors at all and temps between 50-60C

The only odd thing i find is that in Polaris it only has 1 set of straps 0: which is why i havnt bios modded them.
