1070 is 26 vs 32.
At stock, just like a V56 is 300w while mining at stock. With both cards overclocked and power tuned the 1070 does 32MH at 183w and the V56 does 32MH at 251w, this means the 1070 has a ~50% better has to watt ratio.

http://www.legitreviews.com/amd-radeon-rx-vega-64-vega-56-ethereum-mining-performance_197049

And of course this ignores the fact that unlike with AMD cards, ethereum isn't even the most profitable altcoin you can run on Nvidia cards, so the deck gets stacked even higher in the 1070's favour once Zcash and others get factored in.

Long story short is that the V56 is a better mining option for the money than the V64 (as both use the same RAM with the same overclocking potential), but neither are really that great unless you like the idea of getting lower return for your money while using more electricity.

was trying to replicate his results, i'm fairly certain it wasn't changing voltages as I couldn't get it to throttle the clockspeed whatever voltage; don't have a current meter so also couldn't tell immediately either.

seems like his press driver was better for wattman and/or its broken with vega 64!

Yep I concur, my power draw on the wall socket is not budging at all, doesnt matter if I set 1100mv or 1200mv in the manual voltage control, by all accounts should be seeing a 100w or there abouts drop, should be obvious.

I'm currently doing some testing on it all.

You missed me out... again (you did this to me on FuryX too :p )

Blimey. Just out of curiosity how much money do you make?

Not a lot tbh, but electricity's free so I keep it going.

sorry, was basing this all on Ether Mining , ah yes sorry- just saw more recent one 32 mh/s

Yeah I'm Ether mining. Dual mining Ethereum+SiaCoin. The more recent Claymore miners have bumped the speeds up by 10-15% :)

I had the same problem last night, though I doubt we have the same cause, I had my clamp meter on the wrong PC XD

:D


So, been playing around this morning looking at what the default Wattman profiles actually give us with standard Vega 64. That would be Power Saver, Balanced and Turbo. Just to see the difference in the clocks, temps and the amount of watts going to the wall socket. Got a small breakdown here if anyone interested. I don't understand why AMD recommend a 1000w PSU, absolutely bonkers if you ask me.

There's going to be a bit of randomness in the numbers, not sure all the sensors are reporting exacts at the moment, but I believe GPUz is to be trusted the most.

Power Saver (-25% power limit)
GPUz Core - 1200mhz (rough average)
Temp - 68c
Fan Speed - 2000rpm

36436882612_1a1f40b991_n.jpg


Balanced (0% power limit)
GPUz Core - 1536mhz (rough average)
Temp - 78c
Fan Speed - 2400rpm

36467628861_3225049a94_n.jpg


Turbo (+50% power limit)
GPUz Core - 1630mhz (rough average, did start to throttle at 85c)
Temp - 85c
Fan Speed - 2430rpm

Spent my morning doing some tweaks and benches:

- Firstly I couldn't get the memory to go past 1100MHz - going past this froze games on the menu page.
- I was able to get a stable benchmark on Rise of The TombRaider 7.5%+ frequency on the clock (1882Mhz) and the memory at 1100Mhz. Increasing the core clock by even 0.5% saw artefacts begin to appear.
- However when running Timespy with these same clocks I got a crash at the end of the graphics test 1. Dropping the memory down to 1075Mhz allowed me a stable run through on Time spy. Interestingly, I gained 10 FPS in graphics test 2 in Time Spy with 1882 and 1075 compared to my first test at 1837 and 1050 on the core and memory clocks respectively. The overall score increased from 7339 to 7479.
- the biggest performance gains seem to be from increasing the memory clock compared to the core clock. I seen gains of less then 1 FPS on the ROTR benchmark when increasing the core clock, however once I started to increase the memory I seen gains of 3+FPS.

My memory seems stable at 1105 which gives a nice bump of performance; I don't think even clockspeed changes is actually doing anything (useful) at the moment, I don't see artifacts or anything but performance just degrades; if you put in something crazy like 1900 3d mark starts complaining about the timing error...

Tony, do you know what your system pulls when under load, but no GPU in the equation. Cheers

Can you test with the secondary BIOS please? :)

I'm trying to add a photo of my card but can't get it to work. I'm trying to add from photobucket in to insert image icon but it won't display the image - any ideas what I'm doing wrong?

Edit: ok so I guess I just need to bypass the insert image and add the link!

Really don't link that the tubing is on the front of the card now - was much neater looking before on the Fury X...
