Who ordered the AMD Radeon VII? Lets make a list of Miners / Hashrates / Coins

Hey all, as BTC price has been increasing, daily earning with Vii have been slightly increasing also.
Do you think it's still worth to push these cards to the highest limit possible; DaggerHashimoto @ 91 MH/s . Earnings go to around £1.90-£2 each GPU.
But the temp also increases to around 95-100 degrees.
I know it would be very bad in the long term and the lifespan won't be much long.

Not just this card. But no, why should you aim for best hashrate, not the most efficient? You'll get more returns after your electicity bill if you aim for efficency.

Hey, anyone knows the best PSU to purchase for connecting 6 GPUs?
Just that I don't want to be short of wires as VII uses 2x 8-pin cables.

Thanks

You cant connect 6 GPU's on 1 PSU. There is no PSU on the market with 12 PCIe connectors.

EVGA has 9 connectors. You can run 4 GPU's and if you use a cable-mod (CPU to PCIe) you can run 5 GPU's.
(SuperFlower is the same as EVGA. If you dont need the 2000W, better go with EVGA!)

Seasonic Prime Gold 1300W ATX 2.4 (SSR-1300GD) has 10 connectors. With good undervolt you can run 5 Radeons. But with every energy-spike, every GPU-reset, everything which dont stay optimized will shut down that PSU.
(Corsair and CoolerMaster also have PSU's with 10 connectors. But in terms of quality and warranty they both stays way behind EVGA. Even Seasonic is not the best pick.)

So better split your load to 2 PSU's with a bit of room. If you need for example 900W for 3 GPU's, buy a 1200W or 1300W PSU. The 1300W Gold EVGA PSU's are mostly cheaper than the 1200W xxx PSU's, so the 1300W is the better choice. No need for Platinum and co, if they are only for mining.

Life saver tip: NEVER EVER use cheap 6-pin to 8-pin PCIe adapters to connect just 1 double cable from your PSU to your GPU!!! They will get very hot and if you are unlucky, you can burn down your home!
Another tip: Don't use cheap chinese server/mining PSU's. Protect your investment with quality!

I use a cheap ass 1600W Chinese mining PSU which costs $80 and run 6 Vegas on it without any problems. Of course, buying any no-name Chinese PSUs online is a hit or miss thing. Best to be able to physically look and touch the cables and connectors first before buying them. That way, you will be able to know if the wires and connectors are rated for the said wattage or not. I have one blow up in my face once and another emitting high EMI to the point it disrupted my video signal. But at $80 or lower, it was a risk worth taking.

What is the lowest stable voltage that you guys are using for mining Eth (or XMR)? I have lowered it down to 1.0 (1.17 originally) so far but I haven't tried to go below that yet.

Mining xmr currently @ 1550/1200/0.858 (w/o particularly detailed tuning.)  Same voltage for eth, but different clocks.

I am at 0.9 (mining ETH at 1600 core and 950 memory), and all is well. I know I can go lower but don't feel like it.

I am mining XMR with 855mV @ 1575 cclk/ 960 mclk

You should be able to get at least an extra 100+h/s by bumping your mclock to 1200 - doesn't seem to change power use or heat significantly.  Or maybe even better by unlocking your mclock w/ ppt and getting to 1250ish (i've been too lazy so far.)

I believe that is a common misconception. If you've secured a low enough electricity pricing with your current power company, you can still make better profits (after the power bill) while happily burning away electricity. The whole point is about finding a balance of revenue vs. efficiency vs. electricity rates. With my rates I have no problem running my 7's all at or above 90MH/s in an open air rig.

the gpu is so hot，no！！！

[felix135]

Hey all,

i have a small rig with radeon 580 and sapphire rx 480. I added one radeon VII and the hash rate is significant lower now. Is there a problem with the driver compatibility?
Thank you

At 90 mhz how hot are your cards, I'm running mine at 75 mhz because they get so hot.

I have not had any trouble at all with cooling.  I have ~81 C on the Hotspot with 1.0 on the voltage and 80% fans.  Remember that this GPU is designed to hit 110+ C before it throttles, unlike most recent gen GPUs that will throttle around 83-84 C by default.

Most of us don't feel comfortable running the GPU at >80C for long periods of time regardless of whether it throttles or not. This is why I am satisfied with just 81 mhs.

78 C with box fans blowing on them in an open air rig (exactly the kind BBT uses). Just undervolt them and make sure they have adequate (external) cooling.

P.s. I think you misspelled Mh/s.
P.s. 2. It's normal for these cards to run hot. They'll throttle down once you reach high enough temps. I'm not sure but I think 83+ C will start throttling.
P.s. 3. If the card is inside a computer case, it's possible you may never be able to run it at it's full potential. You'll need extra cooling.

Good luck!

I have not had any trouble at all with cooling.  I have ~81 C on the Hotspot with 1.0 on the voltage and 80% fans.  Remember that this GPU is designed to hit 110+ C before it throttles, unlike most recent gen GPUs that will throttle around 83-84 C by default.

That's interesting. At least on my cards (AMD 50th anniversary & AsRock cards) around or above 83 C (as reported by MSI Afterburner) I start seeing diminished Ethereum hashrates. I believe this is a core limited card, so any core throttling will immediately impact hash rates.

I have a 50th anniversay R7 hashing occasionally here, and it's very reliable around 90.7 Mh/s. MSI Afterburner says 74 C, Fan speed set at 64 %, Core 1801 MHz @ 980 mV, Memory 1040 MHz, Power limit -10%

Planning to buy two of these. Any idea when prices would go down now that we have 5700 available?

Afterburner does not show the Hotspot temp; I like to use HWInfo since it shows all the temperatures.  The Hotspot temp can easily be 30C higher which would explain why you have throttling at 83C in Afterburner.

Prices going down in the beginning of a bull market, you must be smoking some pretty good stuff... LOL

[SchroedingerC]

Well... I think I'm going to sell my 13 gtx1070 (eating 130~150Watt each) and one of the rig-packs (MB+SSD+Processor+MEM+PSU)
and buy 5 Radeon VII instead, and then undervolt 'em (200~220Watt each) to have same 400 ethash for less energy -$

P.S.
Those 1070's already passed their ROI long time ago so I don't care about Radeon's ROI, only hashrate/energy effectiveness
