I need help? help when it comes to undervolting my system when dual mining.

I have 6 Red Devil Golden Sample Edition cards, i am using claymore 9.7, afterburner beta 16

My issue is when i am single mining #Eth i can undervolt via afterburner to the lowest settings which 950 (ish) and system follows this settings.

When i am dual mining without setting afterburner to limit voltage, my system uses up about 1450w, so i try to limit voltage to 950/1100/1300 and none of them are respected. i am a little stuck on why this is and just seek my help from those who are having this issue.

Have you guys tried the new AMD Beta driver just released specifically for Mining?
I got my MSI RX580 Armor 8GB with hynix memory (flashed with modded VBIOS - 1750 straps copied to 2000)

With Epoch 139 now my card was down to 28.3MH/s. With the new driver I am getting 30.5MH/s

I found that after installing the driver do not patch the driver.
Use AB 4.4.0 beta 16
The undervolting does not work well for AB, but i used Global Wattman that installs with the driver, Set Voltage manually to 990mV but it didnt work, so changed it back to Automatically. After that it applied the 990mV correctly.
So the ADL API is very buggy with the new driver but the driver definately solves the hasrate drop on Polaris. (Do not specify the clocks or voltage in claymore miner as it does not work)
AB sets the Clocks fine, it's just the voltage that is a bit of a problem.

GPUcore is 1250, Mem 2200.

what undervolty worked for you mine seems to crash when i undervolt it around 100 and 50 where is stable shows no watt difference

I'm using the voltage values recommended by 1stminingrig when I downloaded the rom from there and it's been working like a charm for 90w, I haven't done any further customisation but it can be a good starting point for you

what should i change to reduce the wattage the gpu uses since i know have my memory OC and my gpu core underclocked. am using srbpolaris is a value for tdp but also a value for max power limit and small power limit? or if its the VDDC i should change what is a good vddc for a 1100mhz core on a rx580 an rx480

Dear all, would like to post my findings about power consumptions - I use RX580 with 4GB - the normal polaris and one 570 nitro. I'm measuring the whole power consumption of a rig. The board with cpu is consuming about 60W. A whole rig with 2 RX580 and the 570 consumes about 500W - this means a power consumtion of 150W per RX. With the tuned RX580 I get 28Mh/s and with the tunded RX570 nitro+ about 27Mh/s. I expected more from the nitro+ (has Hynix), but I checked several stripes - no way to get more out. Think experts like matttev can get the last percents out, but I don't think it's possible with only 80W per RX580. It all depends on how to measure the power consumption - it's easy to get wrong on that.  

now i go to launch the ati flash utility it says error reading from rom?

there asint no way people are getting 29-30mh.
i have a sapphire nitro+ rx 580  8gb speacial edition only got 26mh copied 1500mhz all the way up and set memory clock to 1900 as was crashing at 2000mhz anymore pointers expecialy on reducing power

if i offset the mv to 975 or do i have to change the max wattage output?

also do i need visual redistribution files 2012 or 2013 installed?
i have amd drivers 17.7.1

help please get more out my card i flashed it

thats great results, good job man

i'm modding HYNIX and samsung rx 580 8GB and RX 480/470
to get best temps/power cous/ hashrate

up to 30.6XX~ stable without errors modding 20$ each card, if you're interested please Send a PM

Ive been trying to setup my rig for dual mining
Its running 6x XFX RX 580 GTS XXX (Hynix)

I've edited the memstraps already

Cant seem to get more than 500 MHash on Decred on dual mining

I am getting 29.4 Mh (Eth) and 540Mh (Decred/Sia)

Claymore settings are


cclock 1150
mclock 2190
cvddc 850
mvddc 950
powlim -20
dcri 19

Even at stock voltages I cant seem to push the cclock any higher without it crashing.
My understanding is the cclock affects the decred mining hashrates.

GPUZ is showing an average 115v

Hello
It does not let me go down more than 100mV, so I do not go under 1025.
I have copied your settings and it goes very well, but with the mV at 1030.
How do you lower it?

thank you very much

How I can lower the vcore in PBE? I know that 65xxx values are dynamical for support all cards so how I can to decrease vcore then?

I read a lot and check a lot of bios and only values changed are mhz, sometimes go high as default and sometimes are lower.

Thanks

I have literally spent days on this... I ordered 60 RX 580 Nitro+ 8GB GPUs over a month ago. The first round of them started showing up this week (First two that I tested with are Hynix mem). Out of the box I was getting 24Mh/s. Updated drivers and was getting 21Mh/s. I spent hours and hours looking for info on how to get my hash up and was getting no-where. I had a min panic attack but then came across the below post.

http://1stminingrig.com/best-bios-rom-sapphire-nitro-rx-580-8gb-oc-hynix-memory-30-mhs/

User Ti posted down in the comments how they got it up around 30Mh/s (Real Solution). I did what was suggested and was getting about 28-29Mh/s. I just like you wanted that extra 1Mh/s as that plus 60 GPUs is a big deal. I tweaked and tweak in TriXX and below is how I am currently getting in the upper 30 and even 31 on occation Mh/s

GPU Clock: 1275
Mem Clock: 2300
GPU Voltage: -66mV

for the most part it seems stable but only been running for like an hour. I'll post back if anything changes. Good Luck!

EDIT: Once I started hooking up more than one GPU to the rig it would crash. Getting VM_CONTEXT1PROTECTION_FAULT_ADDR while trying to mine on SMOS. In Windows 10 once I would plug in the 2nd GPU the first would hash 1-2 Mh/s below the norm and the 2nd GPU was hashing at 4Mh/s total. There is something wrong with running these cards in windows 10. I've tried driver version 17.1.1, 17.4.3, 17.4.4 and 17.7.1 and all react the same. If I don't have an HDMI plugged into the card running a monitor the Sapphire LED goes off after boot and I can't get any temps or readouts. If I start mining with it the LED comes on but I can't see any temp/fan read out in Claymore and it gets very hot. Overall just very glitchy and unreliable in Win10. Why would running 2 GPUs cause this? Any ideas?

Right now I have it stable for about an hour in SMOS (ETH 29Mh/s - SC 585Mh/s) but I had to reflash the bios and remove all undervolting. Just have copied mem straps as suggested in the link above. Only downer is that each card is pulling 180W as before with the undervolt it was under 100W.

If anyone has successfully got these running (6 or 8 gpus) on a rig and stable around 30Mh/s I would really like to know the secret magical settings. Any help would be very much appreciated.

What are you mining?  Have you made any changes to the clock / memory settings?

Hi, I just flashed my shappire rx580 nitro+ 4gb oc. I just put 1:1500 timmings to 1:2000 and 2:1500 to 2:2000.

Result mining was the same. 24 mh/s. Im looking how to get best results with hynix memory but I dont find how. Any guide or any help? Thanks

Thanks to everyone who has contributed to this thread!

I'm looking for help in getting my 2 XFX RX 580 GB Hynix to hashing > 30 Mhs.  I'm close and getting a consistent 29-29.5, but never go above 29.5.  I've made the following changes:

GlobalCore 1200
GlobalMem 2175
GlobalPowerTune 3
Globalminer Claymore (9.7)

Modded the GPU Rom to copy the 1750 Mhz Timing setting to the 2000 Mhz setting.

I've seen several instances of people getting over 30  Mhs with this card.  How can I get that last 1 Mhs?

My numbers are based on single mining ETH.

TIA.
