Hey,
I have just assembled my first mining rig, with 2 Sapphire RX580 Nitro+ 4GB. I am getting a Hash Rate of about 17 per card. Below if the log, please assist.
Second thing I would want to know is that when I disconnect my display cables, the Hash Rate of one graphic card goes to zero. Does the display need to be connected all the time ? what is the alternate way ? why is this happening ?

Thank you.

For first, you have to BIOS mod it ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif)

Axe, not contradicting anything that anybody on here is saying (as i`m just getting back into this).
What i will say though is in relation to your display problem there really ought not to be any problems in disconnecting the cables. I have 2off sapphire rx580 nitro + cards in my new rig and I only had display cables connected to them during setup. The cards have never had video cables connected to them after that as i just use the mobo (AS Rock H110 Pro BTC+) video out. I know this doesn`t solve your prob, but it does let you know that disconnecting the cables shouldn`t have any affect. FWIW i`m running the current claymore miner on zec.
Actually on second read of your post i note that your cards are 4GB where as mine are 8GB. Wouldn`t think this would make any difference, but someone else may be able to advise.
Hope you get fixed up.

Hey, Thanks! You have a cable connected to the mobo out? right?

Hey Smoolae, Thank you. Have modded the BIOS. Getting a hashrate of approx 19.2 on each card. What further mods can be done ? Also, in case of overclocking, what is the correct way of doing it, without risking burning out of the GPU.

Axe,
Yeah that`s right bud, I`ve got the DVI out of the mobo connected direct to the tv (using it as a monitor) via DVI -> HDMI cable. That allows me to view the full desktop, the claymore miner, the sapphire realtime settings and the zwallet in a decent resolution and a readable size. I did disable the colour option of the claymore using the "- colors 0" option though as the red text was a bit meh to read. Also i changed the intensity to 7 using "-i 7" and i`ve only had 12 rejected shares out of 3480 mining zcash at a stable 311H/s per card at 47 degrees.
BTW not sure if the hash rate there is H/s or MH/s as claymore states Hs and the header of the pool states Hs but the graph of the pool states MH/s. Maybe somebody can clear that one up for me? The pool is flypool if that helps.

Hello.
I have 6pcs Sapphire RX580 Nitro+ 4gb on fresh install windows 10, and the mobo that I use is biostar TB250-BTC. I haven't done any OC and mod yet. The hashrate that I got are 17.xx, 17.xx, 17.xx, 25.xx, 17.xx and 17.xx. Why got 5 hashrates abnormal? 25.xx is consider normal hashrate right?
Anyone could lead me to fix this issue?
Thanks.

It's probably a driver issue, if you have installed the Amd-Adrenalin drivers, you have to switch them from "graphic" to "compute" mode in your driver settings. https://support.amd.com/en-us/kb-articles/Pages/DH-024.aspx
