I have a transferwise account precisely because they give you US local account with routing number, etc.

If you use it together with Revolut, you can receive the money in transferwise, then top up revolut with the transferwise debit card and then convert the USD in revolut to your local currency. That way you avoid any conversion fee and also avoid the transferwise outgoing transfer fees

You can get a personal USD bank account in LeuPay. Not sure if i would be IBAN though but you probably just mean account number.
YES it's what i mean

unfortunatly leupay have suspended USD transfert at the moment, and revolut and n26 doesn't have usd personal account number, so i continue to search

Transferwise borderless account has US personalised local account details which is what you want. They aren't crypto friendly however.

Also, there IS such a thing as a US IBAN. European banks use IBAN, so when you have a USD account in a European bank it has an IBAN

This is a typical picture. You are correct about the efficiency. Its often best at ~90% (for many reasons)
However talking about actually using 50% of your PSU's nominal capacity sounds like a completely absurd thing to do.
also to your second point, that's exactly what I meant. Just was typing from mobile via VNC, so it was kinda hard:)
(1KW DC pulls 1.1KW AC with efficiency of 0.9)



Yes, you’re correct. I was not suggesting that you should buy a PSU to run it at 50%. However I would advice not to buy a PSU that you’ll run at 90% or more, not only efficiency starts to drop more significantly, but you also have to take into account degradation with aging

The optimal range of most PSU is 50-70 percent of the rated load.  

simply not so. good quality psu usually performs at loads of 90% better than at 50%.
go and see some graphs at www.jonnyguru.com
fyi also psu output is the number on the box, not the consumption at the wall.



Not sure where you got that information, certainly not at jonnyguru. A PSU peak efficiency is at around 50% and it decreases as you get either lower or higher. No PSU will perform better at 90% than it does at 50%. The reason you can see a lot of tests at higher loads in jonnyguru is because that’s exactly where most PSUs have difficulty hitting their 80+ ratings.

As for your last statement I’m not sure what you mean, but the number on the box is the effective power the PSU can supposedly deliver to your PC components. As no PSU has 100% efficiency, it will draw more than that from the wall to effectively deliver what it says on the box. How much more will depend on its efficiency

PS: Just do a simple google image search for PSU efficiency curve

if it s a good 400w  it should run a 390 with a low cpu

i run my 390 with an athlon 620 what use 90w   on a corsair cx430 (died after 5 month)  when i realize the 12v rail only pull out 336w  when it was actually using close to 400w


i run 4x 270  on corsair 650 (600w on 12V)  for a year before modify the ring (now i have watt meter, i test and  it use 605w at the wall)
5 x 380  on a 1000w   using 1100 at the wall ( now decrease power limit to keep under 1000)

now my 390 runs on a zalman 700w  with an fx8300 oc and an 470 under clocked  (using 690w) max 700w on 12V, i limited the power limit to keep under 700w at the wall

YOU MUST LIKE THE SMELL OF BURNING WIRES--

The optimal range of most PSU is 50-70 percent of the rated load.  You are abusing your power supplies.       --scryptr


AGREED! Unless you had one of those new fancy Seasonic PSUs that are prepared to go 100w overspec and still achieve an 80+ gold rating, and that would still not be optimal, for your current setup you should get at minimum an 850w PSU, and go with a more reputable brand than Zalman.

With an 850w you would still not be in the optimal range of a PSU, but at least it wouldn’t be a fire hazard

Hey guys,
I have a problem which I'm troubleshooting for days, and still not solved.
I got R9 280X MSI 3GB, 12GB of RAM, i3 4160, ASUS H81M-E, PSU ThermalTake 400W

On this setup my last gpu 7870 2GB worked perfectly on NiceHash mining ZCash on Claymore's miner, when I set up 280X, there are problems income..
First problem was GPU #0 returned incorrect data! on Windows 10 WITHOUT OC, everything stock. I also tryed many drivers, 15.12, then lastest, everything the same..
Now I got another HDD and installed Windows 7 64bit(Basic theme, not aero), got NiceHash setted up, Claymore's ZCash miner, 15.12 driver for win7, and still the same. Then with lastest driver, same situation. Here I saw another problem, monitor goes off for 1 second and it says "Display driver stopped responding and has recovered".
Can anyone help me, what to do ? I tryed to underclock core and memory, It worked for about 6 hours without error and then it came again, I can't let it run for 24/7 without assistance. Also lower clocks get me about -20.000 sols than stock.
Can anyone at least give me recommendation for batch file for my GPU in this case ?

You're too optimistic in regard of PSU. Check what wattage it is capable of for 12V line and if there are more 12V lines You should balance power for R9280X. It is power hungry card in comparison to undervolted 7870.

Yes, hadn’t noticed that, check your PSU. A 400w PSU is probably not enough, except if it is single rail, and even then it’s pretty close.

I have a 375w PSU and my 7970 won’t even try to turn on with that PSU. I also have a very power hungry cpu..

try v12.2b. If your card works with that version, might can be some r9 x80X related problem, because I have also "Display driver stopped responding and has recovered" popups with newer versions.

Thank you but I think I found a solution. I was googling a lot since that problem started and I found this https://steemit.com/mining/@felixxx/gpu-mining-equihash-undervolt-is-where-it-s-at
If you have same problem and same GPU, try this. My GPU is mining 1 hour without error or rejection on that settings, seems very stable.
I'll leave it mining for more to see if it's stable. All I need is stable rig because I won't be home to assist, restart or something.
Edit : Worked very stable for 2 hours and after that a crash.

My 6GB hd 7970/280x, even with claymore only detecting and using 3GB is getting 321H/s. It’s undervolted to 1.12v as it is a very high end Sapphire Toxic card which originally was at 1.26v and underclocked to 1140mhz from its original 1200mhz, memory overclocked to 2010mhz.

I had the same problem as you and tried to mess with the clocks and voltage but that wasn’t the issue. For me it was the temperatures. The card is fine as long as it doesn’t get pas 72C. As it starts getting close to 75C the display driver starts to crash and eventually the PC reboots.

I increased the fan to always be at 60% and that way the temperatures never go over 66 or so. It solved the issue for me, mining for 50 hours without issue

PS: And yes, AMD Wattman is a pain, it always tries to restore your old settings, everytime I change something I have to uninstall drivers with DDU and reinstall them

Very disappointed with claymore’s miners. For both the Ethereum miner and zcash miner, it only detects my 6GB HD7970 as a 3GB card, automatically reducing the intensity for the zcash miner.

No other miner or piece of softwarehas this issue. Is there any way to override the miner automatically reducing the intensity?

So your disappointed with software that you didn't have to develop or pay for? Just checking. Not to be a dick, but if you wanted to you could go ahead and learn how to code and build your own miner. I get the frustration and the fact that your really just asking a question, but maybe read what you type first before you post. And I get that this guy is making a mint off of his devfee, I wish i could program better than him, but again just think before posting. I also get that this post isn't helping, but after reading sooooooo many similar posts, I barely have a tongue left to bite.

Yes, I am disapponted. You talk like if I’m saying I’m entitled to something, which I’m not doing. I like this miner, and I use it successfully with other cards.

With this card the miner doesn’t work so well due to a stupid restriction that assumes every 7970/280x has 3GB of ram, hence me being disappointed as I expected it to perform better.

Furthermore in a miner where you’re paying a non insignificant def fee, you have every right to expect that something basic like gpu recognition works on a basic level, or that at least there’s a way to bypass it, since it’s clearly made to help noobs, not that there’s something wrong with that, but you should be able to bypass it, since it obviously has flaws as seen here

I have a 6GB HD 7970 GHz Edition, which claymore miner is only recognizing as a 3GB card. Is that slowing down my hashrate? Will it be a problem as the DAG increases? Finally, I’m on Windows, would the miner on Linux recognize the card correctly?

That 6GB HD 7970 is a rare gem. Sell it on eBay, they are fetching a huge penny.

But mine ZEC instead with your 7970, ETH no good for your GPU.

That is right. All my 7970/7950 are on ZEC now.

I’ll probably mine some more ETH until I have the minimum to withdraw from the pool and I’ll then try to mine some ZEC.

I also got 2 gtx 970s for pretty cheap, I guess ZEC will also be better for those
