Cryptocoin Mining?

[Redinit]

Bitcoin crashing today. And litecoin tanking even harder.

I don't think the word "crashing" means what you think it means.

Dogecoins are doing well

Yay for my little 660ti doing 230khs

It's surprisingly easy/hard. :sneaky:

Depends on how you look at it honestly. I have an amazing capacity for research, and have actually been looking into setting up a pool for the better part of the last couple months. I much prefer being behind the scenes setting up infrastructure and whatnot so I've learned how and where to look for information on stuff like this in rapid fashion. Plus being a software dev myself and having had to cobble stuff together from really poor documentation in the past, this is second nature to me.

It's a lot of:
- How well you know linux
- How much lack of documentation you can tolerate (though it's gotten a lot better in the last month)
- How much about the moving parts you already understand (in terms of bitcoin and derivatives)

If you can set up a secure LAMP server, that's about half of it. Secure is a big part of it since these things are a huge target with a bullseye painted on them. A big successful pool will have a lot of coins flowing through them.

The next part is the actual pool software. The popular package out there has gotten a lot better documentation and support over the last month. There's still a bunch of gotchas, but if you can admin a linux box, you should be able to work your way around them.

That said... cron jobs ARE working properly now (had to work around an issue with how I have my server set up). Automatic payouts, stat updates, etc, should all just plain work now without me having to run them manually.

Which software do you suggest? if any

I don't need much documentation.

Anyone mining dogecoin via p2pool, have you been getting payouts? This seems to be an issue.

Now we got some mining going on! Somebody just dropped a whole bunch of MH's on the pool. Can't make any promises on how soon the next block will roll in, but we're rocking over 1.5% of the total net hashrate for KDC now.

edit: I stand corrected... we got another block.

Oh god thats a lot of khs.

I might jump on this.

I'm only doing 220 khs xD

It's a drop in the bucket in the grand scheme of things unfortunately. Nighttime miners are coming online, and the KDC net hash rate has gone back over 1GH/s. That means I have roughly 10MH/s worth of people hashing away here on the pool... it ain't much.

Meanwhile, the two biggest pools for the coin (that I'm aware of) tally in at 315MH/s and 270MH/s respectively.

Like I said, it's a drop in the bucket.

I don't think the word "crashing" means what you think it means.

Except you don't know what I think it means.

Maybe I made a mistake calling it a crash, but in my defense on btc-e it had dropped from an $830 high to about $730 at that point in time. And then it recovered.

Carry on.

Setting up a pool isn't difficult so as long as you are somewhat well versed with managing a Linux server, I ran one myself before. DDOS attacks, however, make it a pain. My server got hit with 10gbit incoming traffic once our hash rate started picking up... possibly another pool owner or someone solo'ing that wanted to take other miners offline, if I had to guess.

Defending against those kind of attacks can be costly. I had an idea of getting a bunch of servers at different providers, then proxy the traffic back to the main server through load balancing to (hopefully) absorb the DDOS attack, but honestly... it was too much hassle at that point.

Try to get a server with DDOS protection, like a dedicated server from OVH

Anyone here tracking Ethereum IPO?

Apparently being 19yr genius and a scientist does not preclude you from being

1) greedy
2) easily influenced by established places of power

Which one (or perhaps both) is the case with Vitalik, that I'm not sure of.

There's a problem with mining here. I have an overclock set in MSI Afterburner, but when I run anything while mining, my GPU drops to stock speeds. It doesn't hold onto the overclock anymore, and everything slows down. None of my settings were changed and everything was fine a few days ago. Anyone know what I can do to fix this? Restarting the computer doesn't fix this and I literally have ~30 Hash/s when this happens.

I have got a few crashes when I game at the overclocked yet undervolted settings.

If the GPU is crashing then it will revert to stock settings. Try upping the voltage (or lowering the overclock) maybe to prevent the crashes and see if the same problem persists. Are the temps the same as before?

I assume you're using cgminer? Are you using a conf file?

cgminer has settings to control your video card(s) overclock, fan speeds, voltage and powertune settings. If you run Afterburner before cgminer (which likely you have it set to autostart with your system), then start cgminer with the various parameters set, cgminer will override the Afterburner settings.

What I do is start up Afterburner on the desktop, start up cgminer, then go back to Afterburner and re-apply the settings from the Afterburner gui.

Last night when setting up my 290's I had some conflicts between cgminer and Afterburner. Caused driver crashes, etc. I ended up just turning off Afterburner and using cgminer's GPU settings directly. Worked well.

Temperature and load and everything are the same as before. It's just that it crashes in game, but usually a quick restart of Windows would fix the mining problem. But not anymore. I tried reinstalling the AMD drivers just for the hell of it to see if it'll fix things. We'll see in a bit I guess?

My conf file is barebones so there's less chances of things crashing.

I prefer bat file over config file... For some reason using a config file always gives me errors, although cg miner runs fine (but always screws up my settings)... I use the "-o failover only" for backup servers/pools.

Define stock speeds. Are you saying something like 880/1250, or the stock 2D speeds of 500/150? I've seen issues on my cards where it won't ramp up to the 3D speeds, leaving the KH at 10-50. The solution seems to be a lower TC.

Anyone used those USB cable powered risers?

I've not had good luck, and have just smoked 2 of my mining rigs.

Impressive sparks and smoke came out of one of the PCI-e slots, and the mobo died.

1st time I put down to carelessness. The 2nd time, I guess I'm either doing something fundamentally wrong, or there is something wrong with one of my riser cables.

Did you plug them in backwards? I think the tab sticks out toward the back of the MB/case. I've seen a picture of it but I can't find it right now.

Edit: found some pics: http://www.poweredrisers.com/

 

[Attic]

Well newegg.com now lists the MSI 280x for $499 and you can buy up to 6 of them. Tigerdirect has it for $399 with a limit of 1 per customer.

I'll be doing much more of my business with Tigerdirect going forward.

Ah. Those are my exact risers.

Nope. They were definitely plugged in the correct way round. All the power connections had been double checked as well.

 

[IEC]

Yikes. Stories like that are why I've avoided risers.

Wow, that's hillarious! Way to go newegg!

They were $439 on newegg up until yesterday, or perhaps even this morning. Newegg is taking advantage of the fact that it is the best and most reviewed 280x on their site...

 

[thilanliyan]

Yeah the Newegg prices are a bit ridiculous from a consumer perspective. Thankfully my local PC shop doesn't gouge like newegg.
