Why are transactions so ridiculously expensive? "sweep_all" wants to take 8% (1200 ETNX), whereas ETN was only 0.000008% (0.12 ETN). Did someone get a decimal point wrong?

I'm looking for a working Delta 2400W PSU from a forum-reputable person, preferably (but I suppose not required to be) in the US. I'll cover shipping.

Able to pay with USD, XMR, or ETH (or Shapeshift to whatever you want, if you're willing to take on the conversion fee).

Any idea if you'll ever get more of these?

Yes, when reference cards were made, only Samsung had HBM2 available. The aftermarket cards were late in part because Hynix wasn't ready.

In my experience, no; it depends entirely on the memory. Many (all?) aftermarket 56s are using Hynix memory, which doesn't perform anywhere near the Samsung memory present in all reference cards, and aftermarket 64s.

Checking in as another 8x Vega miner, though on the ASRock H110 - 15,760 of that sweet Monero hashrate, every second.


On topic, I'm glad I found this, as I was actually expecting to be able to run 18 RX570s on this thing. Though is the limitation the motherboard or Windows?

(Edit: After seeing other threads, I see the mobo won't even POST with over 13 of the same card... very weird, I definitely don't understand how any motherboard would care which GPU manufacturer is being plugged in, though someone mentioned potential display outputs, which is an interesting thought.)

No, they are not "forcing you". That's a voluntary choice you make and agree to by choosing their one-click binary download. It's not like they're the only XMR mining software in existence. You are free to support another project that provides binaries with no fees.

If you do the work to modify and compile, you are free to make whatever personal changes you would like - they even walk you through how to do it, which makes people's arguments even more ludicrous.

To the claims of the devs not actually doing any work: you only need to see the commit logs to see the amount of effort that has gone into this software. Hundreds of man-hours so that you can click a button and gain credit on a blockchain ledger.  Why do you not see value in giving them a modest amount of support and incentive to continue to invest into the software?

Would have had to be Samsung; Hynix didn't have theirs available until the aftermarket boards which didn't start production until what, 4 months into Vega lifecycle?

PowerColor got a bad rap, but I think it was just silicon lottery for the ones doing public benchmarks. I have a family member with a reference PC Vega 56 with no issues.

Which drivers and OS are you using? This may be Vega-specific, but I'm fairly certain that 8 GPU was the limit on the August Beta Blockchain driver, as well as Windows 10 before the Fall Creator's Update. 

Also note that the Win10 "Fall Creator's Update" from October(?) did specifically increase the limit, though I don't know what the maximum is now.

The way I do it is to use HWiNFO64 to monitor voltage, and set core voltage to 900mV. If that takes under load (Cast/Stak is stable, and HWiNFO reports core at 900), then I'll try dropping it to 881.

Of course, I've only been successful in about half of my cards (7 of 14), but many of my others are in the low 900s, which will push the draw up to 180W or so which isn't bad; I could probably back that off and hash around 1900 at 150W, which may be more palatable for some.

You can always extract the bundle (using 7Zip or WinZip) and simply point Windows to the Packages\Drivers\Display folder when installing a new device, or do a Custom Install and unselect AMD Settings.

As you've already done, use OverdriveNTool for AMD cards.

Try flashing your card with the Vega 64 BIOS and re-applying the registry mod (use the 1100 HBM to start, to see if it's stable).

If you're mining Eth, use Adrenalin.

If you're mining XMR, use the Blockchain drivers for Vega; Adrenalin if you're using Polaris (since you have the Compute switch).

So far, yes. I've tried booting with 1 + 2 and 2 + 3 and neither configuration would allow Windows to see it.

Curious to try 1 + 3 sometime, but that's for another day. But as long as you have a 300W PCIe cable (i.e. dual 8pin), it's a $4 fix for an 8-pin splitter.

Download GPU-Z and find out who manufactures the HBM2. If it's Hynix (and it probably is), you may be SOL in terms of mining performance - at least until AMD fixes their software so that Cryptonight workloads utilize the Compute drivers.


NewEgg had them. I own a 56, and a family member has two 64s.

It was my understanding that when the reference cards were released, Hynix didn't even have HBM2 ready yet (which was part of the availability issues).

Either way, there are definitely 56s with Samsung (another). But now you have me wondering about the weaker cards in my fleet.

FWIW, while I don't know anything about the Nitro, the MSI Air Boost (which looks the same as the reference cards) does not perform the same. It seems to have Hynix memory (according to GPU-Z), and I was never able to get it to work even remotely well.

I'm using an ASRock H110 with 5x Vega (soon to be 8, once I get my 240V circuit set up) with no issues. I have seen mixed reviews, so it's very possible that with such niche hardware, the failure rate is a bit higher.

I actually did this math last night while talking about the inflated Vega prices.

If you're only talking two 570s, a single Vega 56 is going to give you more hashrate with less (or equal) cost, and less power draw. Three 570s has its benefits, but you're just making your power company happy.

My numbers may not be representative of anyone who has really dialed in their settings, but think of having to do that 3 times more than a single Vega. I am taking into account the average person's experience.
