Topic: Any word on amd vega hash rates? - page 33. (Read 202722 times)

Not anymore my friend. A 1080Ti, albeit overpriced, will now net you more per day than a Vega. If the Vega was priced at MSRP then there would be no contest. But at $800+, there are better choices out there.

 Why wouldn't they? A modified vega gets double what a 1080ti can net you in returns. Even if it's cryptonight/ethereum only there are these things called Exchanges where you can then convert to your coin of choice. Not sure if you've heard of them before.

lol, been playing with blockchain and adrenalin computer drivers for Vega FE

Previously had 2 FE's running at 2000H/s+ but highish power, now stuck at low hash with low power



Showing 349W at wall for 2 cards + mobo but memory stuck at 500MHz despite overdriven tool set at 1107

This gets 1200H/s on each card

This despite a clean load of drivers, bounce etc

Can't seem to get the balance between low power and performance

oh well keep trying for 2000+ at 150W

PS  Fixed one thing - now 1600H/s at 150w each

No, it is not just cryptonight...
ETH is a good too 44,5Mh/s

Who is buying these things at 800 dollars? At that rate why not go with a 1080 Ti? The Vegas are only amazing at Cryptonight from what I can tell.  Almost a cryptonight ASIC as a mining card...

just got the gigabyte vega 56. wondering if there are differences between the various brands this time.

Just checked the power comsumption direct on the 12V lines.
Complete system system celeron g3900,4gb ddr4, 320gb hdd,3vega56@64 Bios hbm2 1050mhz/900mv gpu 1403mhz/900mv@Overdrive, dps-800gb server psu
Vega 1. 8Pin 5.42A   2. 8Pin 4.96A    riser 2.07A   complete 12,45A x 12,1volt 150,64 watt

1,77A x 12.1volt to mini psu for mainboard,cpu,hdd = 21,41watt
complete system 520watt on the wall and around 5500h/s with 2vega, and celeron also on xmr.
So psu efficiency from 90,57%, arround 80 PLUS Gold and 80 PLUS Platinum. Not bad

And it seems not that only the fan is from the riser powerd, but didn't removed it

Prices are a little crazy but cards are out there. You can grind away on the local secondary markets - craigslist, letitgo, etc. I been fairly successful going that route.
If you believe the ads, my local craigslist has 30ish Vegas for sale - granted all used and at 1.5x prices

The ASUS ROG Strix, Sapphire Nitro and the Powercolor Red Devil have been out for a while already lmao. There are people already using them. They sold out imediately as soon as they were made available. There are people already mining with them lol so good lucky trying to buy more than 1/2 at an inflated 60%+ price.

As I said above, one of the possible changing variables (everything else is fixed by deepfreeze) was the cards temperature. Raising the card fan speed didn't solve the issue. They all sit at about ~55ºc (hbm 65ºc).  


The drop is about 300 h/s on each of the 4 cards. It appears to happen simultaneously on all cards.

What miner are you using? Any recent temperature increases on the cards? Are temps in check?
Assume it was a significant hash drop?

I am using a software called DeepFreeze on two 4xvega56 mining rigs to freeze any changes in my working virgin windows/vega installation.   



The freeze state boots with a fresh windows installation, no updates whatsoever,  with the  23aug blockchain drivers manually installed by device manager, and no regedit mods.  A virgin installation.  It always boots in this state.



After booting, I have scripts that apply the regedit powerplay mods, reboots the drivers using CRU.exe, uses devcon.exe to disable/enable the cards a few times in a row, and finally applies a custom overdriventool.exe profile , followed by xmr-stack-amd.exe. I never had a hashrate drop in one week of running, tested across many reboots.  Always static performance.  until now....   



One of the rigs, after running perfectly for one week without hashrate drops, its now beginning to drop the hashrate after a few hours.  Again, windows installation is frozen to the same state as one week ago. No updates, no driver changes.   This hashrate drop purely caused by another variable affecting the cards.  The other twin rig, has no problems whatsoever.

I have tried without success to:
- Decrease core/mem speed
- Increase Fan RPM by a lot


My latest try was to increase the voltages, which were already on the high side (0.980v).



If someone has a clue as to why 4 perfectly running vegas started to hashrate drop in a frozen windows installation, please share!

New models are coming.  Sapphire has a nice 3 fan version that ressembles the FURY they had a while back.  But until those get on the market....there wont be any for sale methinks.  And when they do...profitability is really good so they will fly off the virtual shelves.

Same here, that coin seems to be getting some attention.

Is it possible to test if nytro vega can work only with just 2  pci-e power ?

Thanks for this very helpful thread. 

At this rate 2020 lool :p

Interesting friend...is he the unicorn farmer in the Dos Equis commercial...

Would love a screenshot.
