I have a BIOS switch so no worries.
I think i'll keep -120v. It's stable and i'm getting 1870-1880h/s out of them for ~870watts.
And i haven't had any shutdowns....
With one gpu i have to lower the core/mclock because i'm getting " GPU#4 is returningen incorrect data".
Other then that ....

I have a six rx570 mining rig currently.
Stock 1250/1750
I have them running in TRIXX @ 1325/2000/ -15%/ -120V
I was wondering if i would unvervolt them to -200V, if that would be to much for the cards to handle ...

I've tried MSI afterburner and same things happen, but i can't even undervolt on MSI, its locked.
But if can't underclock on CCC, then there must be something else going on.... i guess

So this is how it stands now with the card.
I did a fresh OS Windows 10 PRO install build 1709.
And PC normal work, doesn't act up anymore.
Still having GPU problems tho, it seems i can't underclock the card anymore.
Whenever i set the clocks in TRIXX, they just reset to default clocks.
In CCC i can underclock the card to 970, and thats it, the slider is at the end ...
If i alter the memclock in ccc, it reverts back to default clocks aswell.
When i try to set undervoltage before running miner.bat, usually when i get to -100, screen turns black and have to do a hard reset.
When i try to adjust the voltage whilst mining, i can get it to -120. But with default clocks.
I'm trying to get 940/1250 -15% and - 120v for optimal power conumption.
I have tried to play a game, and i'm getting lags, small shocks, and white pixels on occasion. Is my card getting artifacts ?
Anybody suggestions?

I think something is wrong with my card.
Whenever i even adjust the slider of the voltage in TRIXX.
Screen falls out. I tried to play a game. And the game freezed aswell. Computer is also acting up. Chrome not responding. Apps take Longer to open.
I DDU'ED and installed latest drivers. Did a driver check. Installed ALL older drivers.
Problem still persists. Using 2 different bios.
Is it a GPU problem of maybe mobo ?
This is a used GPU card.

Is that hash rate with the Cryptonight algo? I assume so with such a number of rejected shares.
Claymore Equihash I'm using a switch box with internetcable. I'm doing another testrun as we speak, 2 hours in and 800 accepted and Rejected 1. I'm going to do another 12hr test, and check the results, so far its going good. |

Windows 10 PRO 64 bit with 17.10.1 Crimson AMD drivers and Sapphire trixx. - Intel Pentium CPU G4400 @ 3.3GHz
- 2 x 4 GB DDR4 Crucial
- GA-H110-D3A
- 1000w 80+
- 6 x RX570 Red Dragons (elpida) Last night did a testrun, i got 6000 shares and 40+ rejected shares, to much OC? Sapphire Trixx settings : Coreclock = 1325
Memoryclock = 2000
Powerlimit = -15%
GPU Voltage = -120V Getting around 1870 - 1880 h/s with 875w at the wall. But with those many rejected, i think i should reduce my OC? Is -120V undervoltage to much for the cards ? Tips & ideas ? |

Ow okay! I'll try it out and report back.

I've never used something like that and i'm afraid i'd Mess up my card or use wrong setting. Ill try the underclock first. U said 0,85 - 1 ?
Does that Mean -85 to -100? In TRIXX
Thanks

Okay Will do. Is there a program like polariseditor u van use to set memory straps ?

No default is 1010 and 1500. I'm trying 1100 and 1600.
1100 and 1500 and -100 works.
Which setting should i de for optimal hash/Watt.
And shouldnt i need a bios mod...

No i can adjust the voltage in TRIXX but when i try -100 my screen turns black. So maybe i need to mod the bios ?

R9 390 Nitro TRI-X 8GB - Anybody has a modded BIOS for this card - zcash mining
Or is there a tutorial out there. I'd like to have less Power consumption.

It is the same card, but don't take my word for it. You can check the BIOS name in the upper right corner of Hawaii Bios Reader to be sure. I will tell you a secret. In Hawaii Bios Reader if you click on VRM settings and there is a table with an entry which says 0x8D VDDC Offset, then you are in luck. Because here you can enter a voltage offset that will apply to all DPM states from 1 to 7. If you would like an undervolt of, say -100mV, then you would enter a value of 65520. If you need a different voltage and are not sure where the above value was derived, then PM me. If you do this, then leave the voltage values untouched in the PowerPlay and LimitTables. This will work only if Hawai Bios editor shows a table, which it does for my Sapphire Nitro cards. Be sure to read the red text above the table and be sure you know what you are doing. I tried the 1100 option and i got black screened in start up.... Sapphire NITRO R9 390 TRI_X 8gb Anybody has a MODDED working bios? |

Got it working.
~ 890 watts for six cards ~ around 1860h/s.

I'm getting 820-830watts stock
I had it overclocked and undervolted once, at around 880-890watts.
Now i am not able to OC anymore, due to lag on overclock software.
When i do a OC without undervolting, i'm getting 980-990 watts, and when i return to stock, PSU still remains at those watt levels, so i have to do a fresh os install.
I'm trying to get back to that 1800h/s levels with 880-890watts, but i'm unsuccesfull, new problems keep coming up so i'm forced to do another OS install
Probably did 15 already in the last 10 days ....
Getting desperate

Window 10 PRO
AMD 17.7.2 minimal drivers.
8GB DDR4
H110- D3A MOBO
1000 WATT PSU
4400 CPU
I'm running @stock 1250/1750, whenever i want to OC. AB and TRIXX are laggy aswell.
I'm getting on avg 112-113 wats but i'm getting flashes of 55w then back to 112 then flashes to 160 .... then back to 112-113, then it repeats itself.
