Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v15.0 (Windows/Linux)

[Wicard]

Hi Guy's.

Sorry a bit of topic.
 
Just some info for the power usage for those not knowing, " I'm no expert"

To get some calculations done to know what you need,

you can calculate you Amp's with " P / V = I "  -- " Watt / Voltage = Amp "
Watt = 2000
Volt = 120v (US)
Amp = ?

2000 / 120 = 16.66666666 Amps

Watt = 2000
Volt = 120v (EU/SA)
Amp = ?

2000 / 220 = 9.09090909 Amps

VOLTS TIMES AMPS EQUALS WATTS--

The formula is stated " V x A = W", or, rearranging :  "W = V x A", and further, "A = W/V", or "V =  W/A".  Sometimes, you will see electrical equipment rated with "VA" instead of "W".  The term is identical.

The important lesson here is that a 2000W load on a 120V circuit causes a greater flow of electrons through the circuitry.  Quoting from academic.pgcc.edu/ent/ENT%20171%20Online%20Project/current%20flow.htm below:

"Current Flow is the flow rate of electrons. One ampere of current is a flow rate of 6,250,000,000,000,000,000 electrons per second. As you can see, this is a very large number and the ampere (amp) is a large unit of measure."

So, the greater flow rate in lower voltage circuitry results in more heat being generated as a by-product of electrical resistance.  Is a BitCoin worth burning down an apartment complex?         --scryptr

P.S.  -- 2000W in the USA is more than most household circuits can handle.  An ASRock H110 Pro BTC with 13 FURYs, R9 280Xs, or VEGAs, with a triple PSU rig on 120V means you better have your BTC wallet on a thumb drive and can run faster than the fire.  And the police, and the victims relatives.       --scryptr

That's a great explanation --scryptr , I merely aimed on Watts for the guy's that would like to calculate the amount of pixies (Amps) they will be drawing.

Calculation , of cause (Watt) W = V x A ( where A = I in electrical terms for current )
also (Volt) V = W / A(I) and (Amp) A(I) = W / V.

the explanation was only for using a 2000 Watt PSU on 110volt supply you will consume 18.18 Amp (Current) and that will be bad for a 15A breaker.

Thanks for reply but how do you update the drivers with modded bios?
Simply remove old drivers and install new and patch? Will windows install those drivers correctly and will recognise the cards?
Sorry for noob questions..

how to use -di to select 10th-12th gpu?

[thepixelgeek]

Hey guys....

I receive watchdog GPU errors only when devFee mining (not blaming Claymore). Error only happens at that time. Otherwise, I go for an hour without fail.

I've switch riser kits, and swapped slot position. Error follows that particular card. Error went from GPU3 to GPU0 as I switched.

Card is overclocked using ubermix 1750 straps. Nitro+ Samsung 8Gb. However, the other card that I used was normal mod using stock 1625 straps copied higher.


Any ideas?

hi, i want the first instance run the 0-7 amd gpu(-di 01234567) and the second run the 8-11 nvidia gpu(-di 891011???), how to do that?

this is an interesting question indeed. Probably Claymore could be asked to add a delimiter between card ids - like "8,9,10,11" ?

I am not sure but when I turn on watchdog, the rig will freeze whenever it detects any issue. It tries to restart but fails and it just hangs there. If i turn off the watchdog, the rig is pretty stable. Maybe it is just coincident? Or there is a bug in watchdog?

My cards are bios modded and i think i will have to patch newer drivers. I was using 16.x drivers until now.
Do i have to flash back ori bios first for install new drivers or just install the new driver, patch and reboot?

I have a modded bios too. I tried new drivers. The patch works.  But, drivers havn't speedup.

For new drivers the patch is the same or we'll to download new patch? Could you link the patch please? Many thanks!

I have a rx580 4G running and I have -ethi 50 in my .bat. It was getting 28.6+Mh/s, then 1-3 days ago it started TOPPING at 28.4Mh/s. I started examining things and noticed at start up of the miner it is now saying -ethi max value is 16 after my .bat commands show in the miner. Why has the -ethi value been maxed at 16 now? A .3Mh/s doesn't sound like much but every bit helps, right?

Your hashrate might be dropped because of higher DAG

I'm really wondering why the -ethi is now maxed at 16.

I think Claymore's watchdog pretty much suicides the rig on most hangs - mainly because if the thread gets stuck on one GPU, the rest will continue mining as long as each GPU has its own thread. Attempting to restart the application is going to cause it to hang...

Makes sense. If watchdog can gracefully end all other thread it can then restart successfully...

Hi Claymore/Guys,
What is the problem If I'm getting this in the Claymore logs? Thank you.

"330          Failed to get OverdriveN Capabilities"

Hello,
I have the following error:

How to correct?
I have 4x RX 570 4GB

Hello,
I have the following error:


How to correct?
I have 4x RX 570 4GB

Usually that error is caused by not having a large enough virtual memory set in Windows. Go to system, Advanced System Settings, Virtual Memory and set a custom size of at least 16000 MB Virtual Memory size.

Hey guys,

I am new to the forum and also mining as well.  I am currently mining on a decent gaming rig.  It's not really a true mining rig as I only have one card in it right now.  I am in the process of purchasing another card, it will be a gtx 1070.  The current card is an ASUS ROG poseidon GTX 1080 TI card that is watercooled in a watercooled system (remember, it's a gaming rig first).  I know, it's not an efficient card, but I bought it for VR gaming and I hadn't really done much to my gaming rig in 4 years and felt the need to upgrade.  Haha.    I plan on just passively mining ethereum around the clock and just keeping it.  I am not looking to break even on hardware price or power usage (especially at current ethereum prices), just slowly grinding out ethereum and sia coin at the moment.  I will probably just hold ethereum until it crashes to nothing or continues to rise, for me it's just a mine and hold mentality for me to see what comes of all of these newer cryptocurrencies.  As for sia coin, I will likely use it to take advantage of the very cheap decentralized cloud storage 'prices' now.   

Anyways...

I had a question about the difference between command line options that seem somewhat similar to me.  The -ethi and -li commands are of interest to me so that I can possibly slow down mining enough to allow me to use my computer at certain times throughout the day.

For the purposes of using the computer, which command line option will give me a little bit of spare power to run other programs other than claymore?  Heavy web-browsing and simultaneous browsing as I have a 4 monitor system. 

Does -ethi simply alter ethereum mining without altering mining of the secondary coin so that changing -ethi may just shift more processing power to the secondary coin and thus yield very little 'relief' of extra power for other things to do on the computer?

I am assuming the -li command lowers processing power across the board for both ethereum and the secondary coin.  Assuming that (we all know what happens when we assume things), would utilizing -li be more likely to 'relieve system resources for other functions on the computer?

Also, these command line options should be input into the start.bat file created by the nanopool config option? 

Any information is much appreciated!

Cheers,
John

Finally I can test and confirm that AMD has fixed the issue with slowdown at high DAG epochs for Vega/Polaris/Fiji cards. They are going to release new drivers in a few days.

Do it mean that we don't need to mix crimson drivers like is described here (http://1stminingrig.com/best-bios-rom-sapphire-nitro-rx-580-8gb-limited-edition-hynix-memory-31-5-mhs/) and we need to use only the new drivers?

I read the article by the link and found nothing about mixing drivers. Please clarify.

halfway down the page  under tools and software needed shows how to combine 16.11.5 drivers with 17.2 drivers

Yep I noticed that too. That's why I always use "-r 1" option with Claymore miners, combined with "reboot.bat" in a miner dir containing "shutdown /r /t 5 /f"
