can someone give me the moded bios for each card im afraid to mod it myself i might destroy the card thanks
for sharing everyone appreciate it in advance 4gb pulse or 4g sapphire thanks

They look like reference cards, with the blower fan. Visiontek calls them overclock editions

Isn't this just reference card?? It's made by AMD!! Reference cards are all same.

I have 2 of these cards, they one gets 22mhs and the other gets 24 with stock settings. They both have elpida memory.

I found a modded bios at http://1stminingrig.com/are-the-rx570-and-rx580-profitable-mining-performance-review/ a member named dragoon posted a modded bios, increased my hashrate to 26 and 27mhs for eth. Anorak.tech has some visiontek roms as well.

Which is better 4gb pulse or 4gb nitro or pulse itx?And more important which one is more quiet?

What os are you running?

Do you have GPT formatting on the OS drive?

Do you have 4g bonding enabled?

How did you get that wattage graph on Afterburner? It isn't there by default and I looked in all the options!

What are you mining?
Is the card bios modded? If so, lower your core clock to 1100 and increase memory to 1900+. If not, you can't have much better results with the power draw.
Also AB is not accurate for power consumption, buy a watt meter to see how much you draw from the wall.

Try reinstall drivers.

No.

I do. 31MH/s unstable, 30+ stable with RX 470 Strix - Samsung.

is there an big different between the rx570 4gb and the rx570 8gb?

Right now im mining with 3x xfx rx 570 4gb and a powercolor rx 570. But when i tried adding a 580 8gb. System reads all 5 cards but only 2 are working. Tried gen1 lane. Tried rearranging the cards. My mobo is asrock b250 fatality gaming k4. Can any one help me here?

I get 29 MH/s per card but does anyone achieved 30MH/s?

any one can help me in this

i have very high GPU power drew

my GPU it's sapphire rx570 pulse itx

Has anyone used a Visiontek 570?  I just got a hold of them and am about to setup my rig.  I'm a bit hesitant to keep them though because hardly anyone talks about Visiontek cards..

Since yesterday I am having an issue with dual ETH/SIA mining on SMOS. Dual mining stops after like 8-10 hours of rig restarted.

Power consumption reduces accordingly on the wall. SMOS shows rig is OFF but actually it is digging ETH as the wall consumption and ethminer pool shows my rig  isactive and unpaid balance increases.

Before this started to happen I noticed one of my 6 GPU's hash rate fluctuates between 19.XX-27.XX. I happens within seconds and goes back up and keeps fluctuating.

I will check power connections and risers for this GPU by replacing it with another GPU  to see whether it works fine on other riser and other GPU works fine on this riser.

Possible reasons:

Insufficient power--> Have dual Evga 850 G2  on add2psu. So power should be enough.
PS1--> Powers 3 GPU (2 on risers and 1 on mobo) and system. PS2--> Powers 3 risers and 3 GPUs on them.
I wanted to avoid SATA-molex adapters so shared GPU/riser pairs on PSUs.


Power connections--> I plugged one GPU on mobo, 4 GPU on PCIE 6 Pin powered risers and 1 GPU on 4 Pin Molex powered riser. Do not even use SATA-molex adapter.

BIOS Mod--> I will decide this after I switch GPUs on risers. If thrashing GPU keeps lowering hash on other riser then BIOS/Volt settings of this GPU might have an issue.

Temprature--> Thrashing GPU is in between two other GPU's. The one in front it has better air flow but but the one behind the middle GPU works fine so far. Although it is breathing hot air from middle one.

Pool--> Using SIAmining. It was fine for a couple of days since I started dual mining. Now it rejects my rig?

SMOS--> Rig is digging ETH now but SMOS says my rig is OFF?


Edit_1: I switched GPU 2 (the one losing hash ) with GPU_1. Now both works fine but now GPU_3 started to fluctuate on hash values And GPU_3 has better space then other cards. It does not look like a riser problem.

Will make another switch to track the problem.

Any ideas?

Edit_2: I managed to specify ne gpu with bios modding problem. Cut its undervolting and gave little bit more mV.

Now system looks ans runs fine.

You can run the card with only the 8pin connected, it will mine. Tested.
Cheers

I'm wondering if the 6 pin is needed especially if using powered risers and undervolting.  I suspect not but interested to hear if anyone has tried it that way.

hi, can someone tell me if there is a difference when using both 8+6pin on the nitro+ vs only 8pin?

my rx570 pulse has only 8pin and gets me 29.4MH/s so I wonder do I need both connectors to get the same hash on the nitro+?

the issue is that I can only buy the nitro+ but putting more than 4 gpu in the rig would require more then 2 psu

So i need to change the drop down in pbe to the other memory and do it there as well? do i need to do the 1:2000 and the 2:2000?
