Topic: Any word on amd vega hash rates? - page 133. (Read 202748 times)

That's great! Mind to share your miner and wattman settings? I'm curious if it's a 64 boost or if vega 56 can reach it too. I still hve the 64 bios installed on the bios #1

Wow! Got it after some tuning!


Only 140watt from the wall!!! 1990h/s!!!

Have you tried... with GPU-z not running?

Have a look at my issue with GPU-z: https://imgur.com/a/lPQNb

I've got 1900h/s without downvolt with high 1600 gpu clock (huge power draw) ... Seems that I'm compute limited with 1400 clock @ 0.9v

I've tried 900, 920,940, 950,1000,1020,1080 mem clocks - all are slower then 1100. Tried with gpu downclock and without it.

Would really love to see your gpu-z screen of Vega56 running 1800h/s to see clocks and voltage

I know nothing about Vega 64 Liquid (yours) but I know 2 things that might help you out reaching higher values:

-vega 56 with vega 64 bios has no difference. same hashes at 1800 with increased power draw. after stock values it appears it's all on HBCC and driver code.
-my cards reach 990 MHz HBM2, but lowering to 950 or even to 920 yields better hash rate. When I was with Vega 64 bios, I too could reach 1100 MHz, but 1020 was giving better hash. Try lower yours and see if it improves your values.

Could you post your gpu-z screen to see what voltage and frequencies you Vega56 is running at?

Thanks, it helps to go from 1600h/s to 1650h/s with my downvolted Vega. 130-140 watt from the wall.
Nice trick with 2 threads.


Update 1. Got 1680 increasing second thread intensity.
Vega56 trick lowering memory to 920 trying to catch tighter timings seems not working on my liquid Vega64 ... speed goes down.

Update 2. Got 1990h/s with only 140watt from the wall
Screen below in this thread.

So you actually had 2 Vega 56s mining on the blockchain driver???

• What were your settings?
• Did you do anything different when installing the driver

Let me know how the regular driver works for you with 3 cards.

As for the lights, definitely green, found this "There's also a green LED that indicates when the card has dropped into ZeroCore power mode, the power-saving mode activated when the display goes to sleep." http://techreport.com/review/28513/amd-radeon-r9-fury-x-graphics-card-reviewed/3

Got my 3 x Vega 56, with original BIOS, doing 1800 H/s (XMR) @ 160W each. Total system on the wall: 570W (cause iGPU is active)

The system is stable, mining non-stop.

64 bios only helps to increase power consumption... unless you use the Soft Power Table at Windows regedit. This method, way more complicated, will push the V56 to stable 1880H/s with slightly less power (560W for 3 V56).

Wattman Settings (Blockchain Beta driver):
-30% GPU Frequency;
950 HBM Frequency;
Fans at 3500 - MAX (Ignore core thermals. What you need is to have the memory below 70º to keep the high hash rate. An undervolted gpu will be fresh enough to not auto raise the blower speed, hence not cooling the memory. At 25ºC ambient temperature I needed 3500RPM set at min speed);
Power Limit -20%.

Globaldrive settings (Blockchain Beta driver):
Crossfire disabled;
HBCC on, at max memory available (I'm with 16Gb RAM).

Important note on HBCC:
Every restart, every time you unplug the monitor/dongle, every time you simply turn off the monitor, HBCC will get disabled and hash rate will go down.
I recommend having an HDMI Ghost/Dummy Dongle like this. It's way more efficient than a monitor 24h powered on.

When accessing the machine remotely via team viewer, go to Actions > Log off Settings and disable the windows log out on team viewer session end. The log of will not disable HBCC but the next log in will.

XMR-STAK-AMD settings (2 threads / gpu):

If you can't have the above settings working stable...
-Do a Clean Install of the Blockchain Beta driver (Clean install on AMD's setup screen is enough)
-Activate HBCC for all cards;
-Apply Wattman settings;
-Start with 1012+1012 intensity and make it stable. That should give you 1600 H/s;
-Then raise it to 1512+1512 intensity. That should give you 1700 H/s;
-Finally, push it to 2016+1600 intensity.

I have three Vega cards at the moment. Two Vega cards work well, as soon as I add the third one, there are gray artifacts after the miner has started and the PC crashes. I am yet to test the non-blockchain driver, though.

You mean the GPU tach turns blue? There is a switch on the back of the card, you can choose between red and blue LEDs. The Vega 64 and 56 cards are identical so I use the LED color to mark them -- e.g. Vega 64 = red LEDs, Vega 56 = blue LEDs.

Very convenient.

Great
They shipped to EU?

509€ with the code !!

Yeah I can reach 44MH on small DAG coins at 130W per card with a 0.875 core voltage.

I've also hit 1500+h/s on XMR but that was on blockchain drivers. Unfortunately there's issues keeping the voltage set to anything and wattage was 220W+ per card.

130 watt for 1600h/s - this is diff between idle and mining with one card measured from the wall, so guess total is near 150 watt ... much more for 1700h/s cause you will need max gpu clock and voltage.
Temps are fine for me - I use liquid cool Vega ))))))))))))))))))))


And one more ... Vega seemes to not need monitor or dummy plug attached for tuning - very convinient ))

Same issue for me. I have 2 Vega 56s with stock BIOS.

1 card works fine with blockchain driver and I get 38 Mhash at 920 mclock. When I use 2 cards 2 I get artifacts on the screen and the system crashes. Also do see that my 2nd cards GPUtach turns green instead of read.

I reverted back to regular AMD drivers and now both cards run fine at around 34 Mhash at 920 mclock  and is stable.

Would love to know if there is a work around or if more folks experience the same issue.

Good video.  I love that guy.  One of the best youtube channels for tinkering with GPU's.  Guy knows his stuff no doubt about it.

1600 xmr is pretty good.  what is the temp and the watts for that?

my amd ryzen 1800x   cpu does 580 h on  stock clock settings  uses about 70-75 watts more  with this rig

Hello guys

https://i.imgur.com/ZXAXSFK.jpg?1
Vega56+64bios+BChain drivers

Thanks for the tips.Dont looking power consumption,just trying to get nice hashrate,this evening will play with kill-a-watt.
PS: Several attemps to get this results DOING THE SAME STEPS, Radeon drivers/software is totally broken..

You need win10x64 with blockchan drivers and HBCC enabled to hit 1600-1700h/s xmr

@CharlieCox and @Rednow

Thank you guys for trying to help!
I increased intensity step by step, an my best result is 1250mh/s witn 2000 intensity. (more than 2000 won't start)
Maybe the HBCC trick is needed to go higher ?
what do you think ?
(I would have tested it already if wattman was working ...)

@Rednow, thank you for the warning about power consumption. This is a single GPU rig just for testing Vega, so it's not a problem.
