Crypto Currency Mining & Graphics Cards

[RussK1]

Yes Russ, I started configuring the 680 for testing last night while I wait for my parts to come this week. I def could use some help configuring and tweaking. Perhaps you can assist me in dialing in some settings. Well I'm off to work, can't wait to play with it later.

The following will debug best launch configuration (be patient). Once you know what it is you can manually write it into the config..

cudaminer.exe -D -H 1 -d 0 -i 0 -l auto -C 0 -m 1 -o stratum+tcp://whatever pool ur using.com:3334 -O user😛ass

This may work:

cudaminer.exe -H 1 -d 0 -i 0 -l K8x32 -C 0 -m 1 -o stratum+tcp://whatever pool ur using.com😛ort -O user😛ass

Benchmark without the latency of the network or pool.

cudaminer.exe -H 1 -d 0 -i 0 -l K8x32 (or auto) -C 0 -m 1 --benchmark

Quoted from the CGminer README:

Additional cudaminer specific command line options are:

--no-autotune disables the built-in autotuning feature for
maximizing CUDA kernel efficiency and uses some
heuristical guesswork, which might not be optimal.

--devices [-d] gives a comma separated list of CUDA device IDs
to operate on. Device IDs start counting from 0!
Alternatively give string names of your card like
gtx780ti or gt640#2 (matching 2nd gt640 in the PC).

--launch-config [-l] specify the kernel launch configuration per device.
This replaces autotune or heuristic selection. You can
pass the strings "auto" or just a kernel prefix like
F or K or T to autotune for a specific card generation
or a kernel prefix plus a lauch configuration like F28x8
if you know what kernel runs best (from a previous
autotune).

--interactive [-i] list of flags (0 or 1) to enable interactive
desktop performance on individual cards. Use this
to remove lag at the cost of some hashing performance.
Do not use large launch configs for devices that shall
run in interactive mode - it's best to use autotune!

--batchsize [-b] comma separated list of max. scrypt iterations that
are run in one kernel invocation. Default is 1024. Best to
use powers of 2 here. Increase for better performance in
scrypt-jane with high N-factors. Lower for more interactivity
of your video display especially when using the interactive
mode.

--texture-cache [-C] list of flags (0 or 1 or 2) to enable use of the
texture cache for reading from the scrypt scratchpad.
1 uses a 1D cache, whereas 2 uses a 2D texture layout.
Cached operation has proven to be slightly faster than
noncached operation on most GPUs.

--single-memory [-m] list of flags (0 or 1) to make the devices
allocate their scrypt scratchpad in a single,
consecutive memory block. On Windows Vista, 7/8
this may lead to a smaller memory size being used.
When using the texture cache this option is implied.

--hash-parallel [-H] scrypt also has a small SHA256 or Keccak component:
0 hashes this single threaded on the CPU.
1 to enable multithreaded hashing on the CPU.
2 offloads everything to the GPU (default)

Can you mine with a Amd and Nvidia cards together on the same Mobo? Does it matter which drivers are installed or which is the main driver?

No you'd get serious driver conflicts if you attempted to run that.

What if you started using the motherboard using latest WARE (softWARE, bios included) so the other card was used using a virtual machine using a different miner using different settings using different driver in the virtual machine?I think you wont get conf.used cuz the card/s wont get ab.used?

Anything better than Newegg? Too little results

Remove the mining kits! So misleading! since when you need hdd? Also if you want to get a good deal build it yourself!

I'm not entirely sure I understand the question here. There's no PC that will run AMD and NVIDIA GPUs simultaneously since there's no drivers that will allow the two different GPUs from different manufacturers. I would not think that running them in tandem via virtual machine would do anything either. You pretty much have to have one or the other.

 

[RussK1]

I had two 780's and a 6850 in my machine. Both AMD and nVidia drivers. Drivers are drivers any way one slices it... Installed the full GeForce package and only AMD display drivers. Mined with no problems...

 

[smeezekitty]

It is sad that TH is encouraging people to make builds just for mining.

Mining with a normal rig on the side is just fine, but component hoarding is not

Component hoarding? lol. Fisrt they're not promoting anything, it's a discussion about it. Second, people can buy video cards if they want. IT's not hoarding, it's buying video cards. Shessh.

 

[cst1992]

"buying video cards"?
you call this buying video cards?

FYI, those there are 108 cards.
This is the thread in which that image is posted:

[RussK1]

What's the problem with someone going out and buying 200 cards with their own money? Good investment/Bad investment it soesn't matter, it's none of my buisiness.

 

[cst1992]

Of course, they're not stealing the cards, I know that.
But money doesn't absolutely transmute to the purchased goods.
Suppose tomorrow, gas is in short supply, so governments around the world will automatically ban those cars which consume a lot of fuel(like many exotic cars, as they only give a mileage of around 5 km/l or 12 mpg at most) and encourage cars running on solar power or electricity.
Because of guys that buy cards in such huge amounts, the retailers have driven up prices(even if cards are available) and those wanting to install r9 290's in their gaming rigs to play BF4 have to buy the card at very high prices.(Graphics cards aren't exactly cheap anyway, I had to save money for months to be able to buy a GTX650 card.)

Can anyone recommend me a mining rig for $500?

Don't mind me asking, but are you a troll or something?
$500 doesn't even buy a mid-end gaming rig, much less a mining rig.

And your point is...?

Defensive huh? You know what my point is... counter to your ranting on a mining thread.

There are others like it... and are about $100 cheaper than 3rd party GTX 780ti's.

Retailers were charging more for AMD cards because people were under the impression nVidia cards couldn't mine (and still are). I've said it for a while now - prices would fall back in line. And they are... you could have saved the fictional anecdote.

If people are foolish enough to pay way above MSRP for a card, who's fault is that. Theirs or the retailers?

 

[cst1992]

I'm well aware the mining craze is going to die down.
You have a point though -- miners are mainly buying reference cards.
and AMD cards have always been cheaper than NVIDIA cards.

It's not dying down, people are buying nVidia cards now because of the efficiency. And to be honest, configuring an nVidia card is much easier than configuring an AMD card. Single launch config vs thread concurrency, gpu threads and intensity.

 

[cst1992]

I just hope NVIDIA cards don't skyrocket too -- here in India the 780Ti costs around $950 already -- because of this mining craze, it'll become more expensive. And I'm only talking about reference cards.

 

[Onus]

What changes is the alternate coin being mined. Bitcoin started it all, but the network hash rate and associated difficulty have now rendered GPU mining obsolete. Litecoin uses a different hashing algorithm for which it may not be possible to cost-effectively design and build ASICs, so GPU mining for them may go on for quite some time.

If Maxwell scales like the 750/750ti, the miners will definitely be on to it.

And now we get the fools gold chasers buying both brands up and driving the prices up.
Isn't that great?

What's fools gold? Something that has actual work behind it or something that is printed out of thin air by some private bankster that lends it out with interest?

 

[Onus]

There are downsides, very definitely. I lost 2BTC myself when Mt. Gox croaked. Of course, people stand to lose a LOT more when the banksters' schemes unravel later this year. Ah, but all that is for News & Leisure, or perhaps another site entirely...

Let's try and keep this one technical please.

haha real work?
Wasting power to crack useless hashes

Printed out of thin air vs digital data.
Well you know. It is all kind of just digital data at this point that is ready to fail
if there is a major disaster. ahh screw it all.

 

[Onus]

The power used for hashing is the price of shedding the bonds of centralized control. There are pros and cons, and the debate will rage on until / unless our currency is once again backed by something tangible. Anyway, I think it is safest to assume that those who are here have already decided for themselves about the merits of crypto-currency.

Ignorance is bliss.

It's such a wasted effort I was able to buy a 240Gb Crucial M500 and pay my electric bill (which I had to pay anyway) and still have left-over coin. All in a months time...
