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

[joseph32]

I bought cheap psus and ran them near capacity and they did fry, burned SATA connections.

I bought cheap PSU from AliExpress and use it over 2 years. The only problem is a noise. Surely, if i had a possibility that time, i`d bought good PSU, smth loke Corsair, but it wasnt so and this PSU works right now.

Thats the same as what others thought until cheap crap burned down their whole existence. Google/YT is full of such stories. Everyone knows someone with smoking/burning parts experiences. Never think it wouldnt hit you too, or in other words, whatever can go wrong, will go wrong (someday).

I wouldnt be proud to such stupidness, sorry mate! And ask yourself (or read about): Why are these PSU's so cheap, and whats the difference between such crap and EVGA for example?

Ok. My friend bought only Corsairs. 3 of them burned down. And this cheap PSU works till now.
And if you read more attentive - you can see why i bought it.
I can speak long about it but everyone has his own point of view.

Corsair sucks, three times i bought this PSU and it takes only a month for each of them to be broken. I moved to the thermaltake and be quiet. So far i never got any problem with it like what i have experienced with corsair.
Corsair is not good at PSU.
Maybe you got a perfect product when i got defective products.

[joseph32]

Yes, there is a reason why EVGA is always at the top of any test. Quality and warranty is untopable. If you ever have a problem in 10 years, it will be fixed asap. I bought hundreds of EVGA PSU's in my life and not even a single one broke down. If you have the choice, go with EVGA.

I still have some Corsairs left, but half of them already have been repaired. Wouldnt buy them again, even if they are cheap like hell
Seasonic, Coolermaster, BeQuiet, Thermaltake and 1-2 other top-brands are fine too. But its always a bit like playing the lottery. Its not a no-brainer.

But b2t now again

Hi guys, I finally placed an order for 2 Vega VII. Can you tell me which miner to use and are the latest drivers the best ones? I was thinking to use XMR-Stak 2.10.4

POWER SUPPLIES (PSU) RUN BEST AT 50-70% LOAD--

Running a power supply at max load will wear it out prematurely.  And, a cheap PSU at max load can fail with a fire hazard because they may be improperly rated.  A 2000W cheap PSU on a 110V (USA) circuit would likely overload the 110V circuit and could possibly cause a house fire, not just an explodong PSU.

A cheap PSU will explode when run at max load.       --scryptr

Thats what I wrote often before. NEVER buy cheap. You only have one life. Saving a few bucks with cheapest hardware is just stupid.

I second this. Most US household plugs are rated for 15 amps. That's 110V * 15A = 1650W. My extension cords get scary warm at already 1250W even without tripping the fuses... So please take care, measure your consumption if you don't know it, and stay safe.

A continuous load (e.g. a 24/7 mining rig) should generally be held to 80% of a circuits nominal rating.  That 15a rating is for transient / short-term loads.  For instance, I have a ‘20a’ PDU which is already derated to 16a to enforce this ‘rule’.

Also, not all extension cords are equal.  You should look for high amp/power cords - ‘heavy duty’, prob 12g or 10g wiring, and no longer than necessary (typically used for large outdoor/construction equipment like saws.)

Also, the longer the extension cord, the more the voltage drop and higher amps needed for same wattage (which doesn't charge if you're mining with same setup).

Yeah what I hear over the forum (and popular YT commenters, such as Bitsbetrippin'), Corsair no longer makes quality power supplies that last. People have been moving to Thermaltake Toughpower and EVGA Supernova. I've personally have had no issues with EVGA or Thermaltake.

Hi there, can someone tell me how to configure SRB miner or XMR stack for Vega VII. Mine arrived today. For SRB miner on do you want to use double threads I put yes but I dont see double threds i am mining with 1400 hashes, please help me

[Michael20]

What is the power consumption on the new radeon VII, optimized or standard settings?

[molivil]

What is the power consumption on the new radeon VII, optimized or standard settings?

Depends what algo you run. Ethereum is 215W for 82 MH/s, 245W for 89 MH/s or 300W for stock settings.

I have 4 dead Radeon VIIs.  After I rebooted my rig 4 of 8 Radeon VIIs would not hash or show u in in SimpleOS.  I replaced riser, replaced the psu and tried plugin one straight into the modo and nothing.  I'm running out of ideas, could I have cooked 4 crads?  They ran fine for a 6 weeks around 83 degrees.  No idea why 4 cards would stop working after a reboot.

Try them 1 by 1 on the mobo to see if they are working or not.

PSU problems perhaps?

All these people having PSU issues in this thread, it's like they've never built a system using 300 watt stock tbp gpus before.

How to size PSUs:

Step 1 - Add up the stock power of all of your gpus.

Step 2 - Divide by 0.8 so that if your OCs get reset and you don't notice you've sized to pull no more than 80% of the psu's rated power.

Step 3 - Take the combined power of your power supplies and make sure your wall socket can provide 15-25% more power than that without tripping the breaker.

Example:

You want a system with a cheap mobo + 4 Radeon VII gpus.

Step 1 - Power Draw = 60 watts (mobo) + 300 watts (gpu) x 4 = 1260 watts

Step 2 - 1260 / 0.8 = 1575 watts, or we need a PSU rated for 1600 watts or higher.

Step 3 - 1600 watts power draw * 1.25 = 2000 watts.  2000 watts / 110vac (rms) = 18 amps, or you need a 20 amp breaker dedicated to just this 1600 watt psu, powering just four Radeon VII gpus.


You really don't want to be maxing your psus out anyway for efficiency sake, you're burning more power by not running closer to the peak of the psu's efficiency curve.

On another topic, I've found that for ethash the point at which the gpu core no longer bottlenecks the memory on this gpu to be when the gpu clock is about 1.8-1.83x the memory clock.  Or 1800mhz core for 1000mhz mem, or 1620mhz for 900mhz mem.  Is everyone seeing similar in their fiddling?

[kibatronic]

I currently have 3 Radeon VII's mining Monero with TRM 0.5.2, core 1500MHz @ 875mV, HBM 1050MHz. Total system average 8434H/s pulling 550W from the wall (this is no estimate, but actual metered powerconsumption).

I finally wound up ordering one today; hopefully I can have it installed in time to tinker with this weekend.  It will be in a multi use PC so hopefully I can get multiple profiles set up for convenience sake.

You really don't want to be maxing your psus out anyway for efficiency sake, you're burning more power by not running closer to the peak of the psu's efficiency curve.

It's unfortunate how tenacious this 'common wisdom' is.  Maybe it was translated from home wiring circuits (where it's def important to maintain 20% headroom when talking about sustained loads,) or it's from older/cheaper/lower-end PSUs w/ more bell-shaped curves, but current high end PSUs have no issue running at capacity.  In fact the graph you pasted shows measurements up to 12.5% above cap - though I wouldn't necessarily test that w/ a 24/7 load.  

As to the efficiency and power use concern, peak eff is around 33% of cap - that would be insane to leave so much unused cap.  Assuming 75-80% is the guideline as suggested, you're talking about maybe a 2% eff drop between that level and full cap.  Which assuming a $0.1/kwh power rate translates into:

((1600 * .02) / 1000) * 0.1 * 24 * 365 = $28

That's $28 per year in extra energy cost by fully utilizing your PSU vs handicapping it at 80%.  Even if you double that (splitting the load will get closer to peak on each PSU,) given that that the AX1600i runs about $470 new, and the avg lifespan of electronics is 3-5 yrs, it's clearly much more financially prudent to simply utilize the full potential of the PSU.

Also, if someone is really worried about a reset-situation kicking the GPUs back to stock, they should just use PPTs.  Although even w/o that, the over-current protection of the PSU will handle what should be a rare occurrence anyway.

On another topic, I've found that for ethash the point at which the gpu core no longer bottlenecks the memory on this gpu to be when the gpu clock is about 1.8-1.83x the memory clock.  Or 1800mhz core for 1000mhz mem, or 1620mhz for 900mhz mem.  Is everyone seeing similar in their fiddling?

I found 1575 cclock was roughly the line for 935 mclock in my case.  Though this was a while ago, on an early bios and older drivers.

did anyone ever figure out best memory timing settings using AMD Mem Tweak tool?
