hmm… thanks for confirming.
I must have fudged up more than just the driver files in windows as I get errors.
Or the BIOS files are not 100% made for my GPU, as I noticed most are 256kb not 512kb.
some bioses are 256, for example asus rx470 oc is
its better you modify yourself - it takes 5 min and requires zero skills
Hey guys, I am getting a very unstable hashrate and random crash with Claymore V2. My rig is composed of rx 470 and a G1840. Any idea ?
Still AMD only? No CUDA support?
try to lower your memory clocks
latest gave me issues. 16.9.1 is my preference
Do you know what frequency for a RX 470 OC ?
for me it’s 1900 with bios mod to 1500 stripes

It’s too old for any of the mining software. I have 2 6970s I cannot use sadly.

v1.1 Linux
Power usage rig: 860 Watt
1x 7950 & 4x R9 280x = 197H/s avg 24hrs on flypool
280x: 1070/1550
7950: 925/1250
Thank you 
How much sol per 280x? did you have to OC it?
from 48~52 in general on stock clocks

So I know you say 15.12, but that driver doesn’t support rx4xx series? SRight now I am running 4 480s and two of them are barely cracking 12 sols/s. Help? All four in risers, tried for five but the fifth makes my system freak

Can you post the custom rom to get those results?
Thx
Im using 16.10.13 the latest (if Im not wrong on the version number) on RX480s
Its @boysie123 31.8MHs ROM - the original post is here:

I have 18 R9 380x Running each at 33-35 h and 2, R9 290x running between 52-50. But i have a feeling that i can get more out of the cards. Anyone have the same type of cards and running better?
Hi guys. I just wanted to chime in with some 390x real world results. Using Claymore 2.1.
6x XFX 390X
GPU Core 1175 (factory 1060)
GPU Mem 1500 (factory 1500)
Also using the new -I 2 option.
ZEC: GPU0 67.921 H/s, GPU1 64.579 H/s, GPU2 64.919 H/s, GPU3 62.657 H/s, GPU4 64.986 H/s, GPU5 67.924 H/s
using -i 2 needs a good CPU… what are you running that machine on ?
-i2 seems to be ok on mid end CPUs as well assisted hash rate on a 2500k (i5) a FX 4300 and an FX 6300 as well.
Up another 5-6% over v 2.0 it seems.
