I also noticed speed drop for sapphire nitro+ rx480 oc for all my gpus
v8.0 29.9mh/s
v9.0 29.5mh/s
I am using modded bios with gpu 1150 / mem 2150.

my system running 1400sol/700watt= 2sols/watt
what gpus ?
i have 1460 sol/s at 940watts at the wall - 6 x rx480

whats wrong with this bat

eu1-zcash.flypool.org:3333 -zwal taddress.rig2b -zpsw x -benchmark 1 -tt 90 -fanmin 50

getting average hash 500+ showing in console and nothing at flypool for over 2 hours?

Are fly pools stats down right now?

-benchmark   benchmark mode, specify "-benchmark 1" to see hashrate for your hardware.

6 x rx 480 8gb - 1200 h/s - wall power 910w - gpu clock 1300, mem clock 2150, no undervolt, bios from eth v4

Getting 860 H/s overall 4 x RX480 8GB Sapphire Nitro+ Core GPU 1400MHz Memory 2100, getting roughly 215 H/s per card, Thanks Claymore
any undervolt?
what is wall power?

Does anyone know which is stable downvolt  for SAPPHIRE RX480 NITRO OC + for 1342 MHZ GPU and 2000 MHZ for memory?

I'm ok with -100 mv
I use a modded bios(which I have posted) and 1125/2080 -100mv works well even with a monitor attached. About 152 sol/s but is only like 55 watts.

@Xardas2014 mind to share again the modded bios?

I have a rig with 6 x sapphire nitro+ oc rx 480 8gb cards and using a modded bios from eth I am getting:
- 1000h/s for about 910w at the wall
Can we get more h/s from this gpu and less power draw?


I have the exact same cards, 7 of them in 1 rig.
1050H/s 780 Watts at the wall.

You need to underclock and undervolt.

I have now with modded bios from eth gpuclk 1150 memclk 2150, gpu core voltage -100mv
6 x rx480 - 930h/s - power draw at the wall 700w
If I try to lower gpu or mem clock I get hashrate drop

what gpu/mem clock and gpu voltage are you using?

5 x rx480, v4 used with -i 0, better than with -i 2
- 378 h/s
- 700w

Hi all,

I have 5 x rx 480 8gb sapphire nitro+ oc.
With claymore's zcash v3.1 and I get the following results:
- 700W power usage
- 310H/s
so roughly 62H/s per gpu

Any idea how to improve hashrate and decrease power?
Thanks
