Bitcoin Discussion Thread Part 2

Should give credit to him and link here ehh?

Also i've been messing around with MSI Afterburner,it sucks.If Rivatuner supports HD5xxx series and higher and voltage control then no way i use AB.
 
That rig ain't mine lol. I saw it somewhere else and shared the pic here. :D
 
So at this point, with the difficulty increases, my chances of recouping the cost of a couple 5850/6950 is pretty much non-existent? I just found out about mining from the H frontpage story and I've got about .75 BTC from a couple CPUs after about 2 days, but I'm just thinking the economies aren't there anymore for dedicated mining rings.

Thoughts?

Wait... so you'd rather fold, using the same amount of power and pollute just as much and then not get something out of it. I'm not trying to knock folding but that logic just doesn't make sense.

I don't get anything out of it but the points.. but scientific knowledge is actively being generated. just because it doesn't produce profit in the form of money doesn't mean that folding doesn't produce a profit on a much wider scale

Like I said I'm not trying to knock folding. I do think it's a good cause. My comments were in response to jebo_4jc saying that he was feeling guilty for bitcoin mining because of all the power he was using and pollution he was creating. Then went on to say he was going to get back to folding.

The best of both worlds would be to bitcoin mine just enough to pay for the hardware and electricity cost of both the mining and folding rigs.

Most folders use far less power than a BTC rig since the majority (atleast on this team) use CPU's, and not 5+ video cards like you guys ;)

I do love the HW pr0n in this thread though.....


note: not meaning to flame out.
 
My 5830s in the garage.

And the 5970 and 5870 in the main rig. (sorry about the CM, didn't want to bother until I get a nice fan controller)

What are your ambient temps like in your garage? How is your hardware holding up?

I put a folding rig in my garage earlier this year and a motherboard VRM blew.
 
The next difficulty jump should be here Tuesday and it is projected to be an 8% increase

Let's hope their projections are better than the baiters.
 
Scored new overstock from a small town computer store, 6x6950's the 2gb sapphire reference models. Currently waiting for them and extender cables to come in. Playing with 1 6950 right now learning the ropes.... seems to do 1000/300/1.3v and between 350-380Mhash, havent unlocked the extra shaders yet.

That angled metal framed case, is that the kinda stuff you put on the corners to screw drywall together? Might be a good cheap material to build similar cases/racks out of.

edit; Unlocked the shaders tonight, doing 408Mhash now, cant wait to get the whole shebang running.

wait...what? 1.3V??!?

wow man...1.2 is as far as I have dared...keep us posted yo?

fwiw I'm getting about 400Mh at 905Mhz/1.2V unlocked with similar cards...how are you guys getting hard Mh numbers?? mine bounce around 376,412,382,422 etc etc
 
I could play further and bring the V down, started at stock 1.1 and i locked at 940, 1000 at 1.3 was my next try, I could probably bring it down, didnt want to waste the whole night guessing/testing before I know if the shaders would unlock i just found someone elses settings that worked online and tried em.

My Mhash do bounce a bit, with Trixx open 377-403 with it closed 403-406-408

edit: machine moved into a warmer room, locked up at 1000 1.3 so went back to 900 1.1 for the night.

When I have Firefox open (With hardware acceleration disabled in FF Preferences), even with [H]Forum as the only tab open, my mhash/s goes from 432 to 388.
 
Do you load the [H] front page then click on the forum link or do you go directly to the forum? If I go directly to hardforum.com my hash rate stays the same, but if I go to the front page then click through to the forums I get a similar drop as yourself.

I resorted to blocking flash/java/javascript and that fixed it for me.

Yeah, for those using CHROME, I downloaded "Flashblock" extension and it works like a charm. You can enable java items individually, or turn them all back on for 1 page.. Keeps my computer from locking up if I hit a page with a video ad.

Sometimes trying to run a simple java item can cause the graphics driver to crash and restart, but thats about as bad as it gets now. I just kill my miners for about 5 seconds and turn em back on and its all good.

sometimes when I restart them I can see the temps dont go back up but my hash rate stays high, not really sure what that means tho.. Have to just do a full reboot to get em going full speed again.
 
wow those rigs above with all the extender cables are crazy, as is 1.3 V. I feel like my video card would catch fire if I put that much voltage into it :p I've gotten to 1005 MHz core at 1.25 V, though that was before I unlocked the shaders. It would prolly need a bit more juice b/c of that but not much.
 
^ lol, skip the flash ads, these locks are not as bad as the ATI FAH client...wierd, some pages lock it, some slow it, some let it be

Ambient is like 90-100+f depending on the day. 2 cards died and are being rmad, I had issues with them since i got them so I'm not sure if its related. The extra space between the gpus helped out a lot now all my cards run ~65-70. I have extenders on the way for when i get my cards back from rma.

I had the rigs in a small office in the house and the room was well over 100 all the time so the garage is actually cooler.
 
Anyone care to tell me whats causing the massive dive in the value of BTC here recently?
-Lack of good/bad news (Publicity)?
-Miners falling out?
-Lack of store support?


Been waiting to sell, hoping it would get back up into the 14.50ish range, but its just been taking a steady dive..

It would make sense that after I start getting into it the prices drop and will start to normalize. I can only hope for another spike.

So basically I *could* profit (BTC gen-electric) if the price holds around $14/btc up until the difficulty is 8E6. I've not really been able to find a good comparison of difficulty to time except http://bitcoin.sipa.be/speed-lin-ever.png which seems to show doubling every 1-1.5 months. At this rate I could maintain profit for maybe 6 months before profits hit zero.

I guess my question is: Will difficulty continue to exponentially grow as it has been or will it slow as people start dropping off? I'm guessing I'd pay off the 2 or 3 cards in about 3-4 months, but it'd be a gamble.

Any thoughts?

The difficulty increase have slowed to a few %. if people stop mining it could even drop. I wouldn't expect another huge spike in difficulty unless prices jump back up over 20.

I think it's mostly due to lack of store support. No one has a reason to buy bitcoins other than speculation. If silk road booms in popularity or real vendors start to take it prices will jump back up. The problem is big retailers cant accept a currency that has wild swings in value daily. And even if they do they are selling the coins right away to make sure they get the money.

So, in a candid opinion, would it be worthwhile to get a few 6950s and mine like there's no tomorrow? I've got free electric for a month (before I move) and then the cards will go into my webserver in my parents' basement which I have remote control. I'd move them into my apartment file server but I really don't feel like running A/C if my parents' basement is always a chilly 60'F. I'd just comp them the electric costs if they even care.

Seems like in the worst case scenario the bottom drops and I'm out a few hundred bucks. Best case I pay off the cards in about 2-3 months and then profit for several months afterwards.

I love when I can logically purchase $750 worth of gear and put them to good use. I've been Folding for years with CUDA, if only I'd found BTC sooner :rolleyes:
 
I guess it depends on how ballsy you are. Assuming you make even a few $ you could resell your 6950s and pocket some money.

I bought 8 5830s a month or so ago and they are pretty much paid off with the help of my main rig. There's no way I personally would get into mining this late unless things pickup. When i started difficulty was 1/2 what it is now and coins were worth twice as much.
 
I hate to say it, but I bought a few extra bits of hardware about two weeks ago. I will not be installing anything more than the 2x 5830's and 3x 6950's I have already. Between getting the cards (unless you buy local retail), getting everything setup and tuned, it may be a few days until you hit peak/ stable so you will be inching closer to another difficulty increase.

On the other side, BTC are rapidly declining in value. At the rate they are going, it is about a 10% per week reduction in value of that which is mined, not including the difficulty changes. On one hand, you could mine and hold BTC hoping for future value. On the other hand you would just be selling into a buyer's market so prices may not support new hardware purchases. I wouldn't be surprised if BTC:USD goes under 1:$10 in the next 14 days, possibly sooner. A lot of people are going to bail on the Radeon market at that point so the value of used cards is going to go down quite a bit too.

Previous poster has some good graphs/ info.
 
Yeah, Im not happy about the $12 price at all. But I knew I was taking a gamble getting into it. I'm strongly considering selling my BTC and 5830 now while I can. The only reason I havent is because I know that people doing exactly that are contributing to the price drop.

That's one way to put it.

Unfortunately I think it's more likely we're watching the slow and painful death of bitcoin

I hear ya. Unless prices turn around I'm selling everything i mine.

It may lose it's popularity but I don't think bitcoin will go away. It was around for years at $0.01. Some people will still mine if the difficulty drops back down.

Yeah..I may cash out 250$ to finalize my hardware payoff since I JUSt hit the break even point, and I might as well just sit on the rest of my coins.. And if the difficulty drops back for a while and prices drop, I may mine to 100 and just sit on that and hope there is another random spike.
 
Much ado about nothing it seems. Speculators were playing chicken racing towards the bid wall. They flinched and value is going back up. What were you negative Nancy's from the peanut gallery saying? You forget that we hit 11 dollars not long ago and value bounced right back up. This is just another dip.
- Oh, by the way, Ruxum is setting up a bitcoin exchange. Google that name and see who they are. :)
Hint: Red Umbrella
Back up to $13 and climbing. Holy crap look at that volume :eek:

HAHAHAHA I just pulled my 5830 out of my machine! I wasnt going to, but we had a lightning strike, my PC wouldnt power back on, so I opened up the case just to check everything out. I figured while I was in there I'd just pull the 5830 and I was gonna say screw it and sell it.

Hah. What an ass I am.
