You didn't describe what your card bios have been modded. So, I assume that you are running your cards on stock bios. You need to mod your bios cards, use blockchain driver. Good luck

hi thankyou for the reply
1 rx 470 8 gb card modified bios and other all on stock bios
tried amd blockchain driver but still unstable n low hashrate


is my both psu are faulty how can I know that ? how to check??

[andydis]

what happens when you mine with just 1 card,
then try mining with just card 2 ,
then try mining with just card 3
then try mining with just card 4

What are the hashrates?

IF they are all ok but when you mine them all at the same time you need a WATT monitor plugged into your kettle lead

like this https://ae01.alicdn.com/kf/HTB1I64nKFXXXXbaXpXXq6xXFXXXn/2013-New-EU-Power-Meter-Watt-Voltage-Amp-Energy-Monitor-Analyzer-LCD-display-5pcs-lot.jpg

IF The one card still has issues, replace the risers, reinstall drivers, try again
if you still have issues try the card in another PC (it may be faulty)

if its ok in the PC again try the WATT monitor, your PSU may be using above its threshold.


basic torubleshooting here.

Hi
Thank you for the reply

Tried with
1 card Rx 470 8 GB Samsung memory
With riser and directly on mobo on 16x slot 
With cooler master 80 plus gold psu v860 watt

With all different display drivers 16. 17. N blockchain driver 18. But it's only giving me 14 -15 Mh


It's 6 months old card

Then I thought may be card is faulty

So I tried
Rx 570 4 gb new card with Elpida memory with riser
Installed drivers from cd cones with Rx 570 wich was I thinking 17.10 radome driver
N surprised
This new card is also giving me 14-15 Mh

What should I chake more, how to fix this

Now I will try it on other Mobo will come back

But thanks for your reply

Software problems?
What mining software you use?
If it's MinerGate you will get lesser hashrate as they steal your hashrate for referral or other stuffs.

What are you trying to mine ? Bitcoin you won't get anywhere.
Use NiceHash it will Auto choose the coin to mine with the highest profit at the time period and exchange it into Bitcoin automatically.

Over clocking? Try over clocking and off to see the difference.

I tried on both
On minergate I get 13- 16 Mh on ETC  etheminer

And on nice hash
15-18 Mh on dagarhashimoto

256hash for equihash

Even you are using new cards if you didn't mod your bios and using the right driver version, you will get low hashrate, that's is basic rules on Polaris card for Daggerhashimoto/Ethash Algorithm. And one more important thing, don't use GUI miner (Nicehash/Minergate) to get higher hashrate, use a console based gateway, such as Claymore.
