Cryptocoin Mining?

[Spike]

Dang, looks like I got into this too late. I'm only sitting at ~2 BTC right now and now it's going sooo much slower. I might go until I get to 10 total BTC, that should be enough to buy a new case for my main rig which was my goal all along.

It almost seems worth it just to attempt solo mining assuming I get lucky and grab a 50 coin block. Too bad I can't get solo mining to work at the moment, oh well.

I was actually thinking the same thing. After I quit pool mining I might try solo for like a week. I found a block last night, but I was mining through a pool so all I got was .066 BTC. Damnit.

.066 for a single round doesn't sound too bad to me. I usually only get around .015 to .02 per round. If I'm lucky, the rounds are short, but sometimes we get a few 1-2 hour rounds in there.

Given the TPQ 1200 is a 1200W PSU, I highly doubt that you'll even go over half of the wattage.

Here's the power usage portion of Anandtech's review of the Radeon HD 6990:

http://www.anandtech.com/show/4209/amds-radeon-hd-6990-the-new-single-card-king/18

I chose this one because I knew it would have the 69XX cards in Crossfire, and it certainly does have the 6950CF listed. As you can see, their setup only used 470 watts in Crysis, and 509 watts in Furmark (which should be maxing it out).

Essentially... 1200W is overkill . Although, since the PSU is 80 PLUS SILVER certified, it should be plenty efficient at that low draw.

yeah newegg has a small sale on the OC version, so it was only like $30 more than a reputable 900-1000W.

I figured that if the power supply is going to be run hard all the time, i should buy a bigger one so it presumably isn't worked as hard.

You are probably using a much larger pool. Rounds sometimes last 5-6 hours on the pool I am using, although they average around 2 hours.

yesterday deep bit had 4 1minute rounds in a row,and even with the increase i'm still averaging 17 minutes

What are the payouts like for you?

 

[hdfxst]

yesterday my average was 14 minutes and .66 btc/24h and right now it's 18 and .54,tomorrow morning i'll see how bad the increase is,thats at 570-580 Mhash

 

[ultimatebob]

My new Radeon 6870 is pulling 265 Mhash/s, which isn't too bad considering that it's installed in a 4 year old PC.

That sucker is putting out a ton a heat, though... The fans are running at full speed, and the case temperature gets up to 145 degrees!

You likely have poor case airflow. There is no way an HD6870 should run at 90-100% fan speed. My HD6950 @ 6970 speeds needs about 44% fan speed to keep it at 77*C-78*C. The 6870 is a cooler card. My previous 4890 ran at 80*C at 35% fan speed. So definitely your case airflow is prob. to blame. A case with horrible airflow (or lack thereof) can increase component temperatures 25-30*C. NO joke.

 

[soccerballtux]

ouch, even a 90$ 5770 does ~220 mhash

I've got 2 5770s OC'd to 950 cores and each only nabs ~195-200.

Thats not bad, I'm getting around .5 per 24h at 500 mhash or so. Ill see what this looks like come tomorrow.

I could have sworn there was a way to fix the freezing issue with AMD drivers, but I can't recall what it is, and digging through 23 pages does not sound like a lot of fun... especially after losing a bunch of unsaved stuff after a freeze :|. Yeah, apparently running the Curse Client is graphical enough to freeze my computer while it's mining. I can even watch 720p videos without an issue... ugh, this is just annoying!

 

[hdfxst]

are you running f120 in the flags?you'll lose 15-20 Mhash but the computer will be more usable.I run 1 card at f1 and the other at f60 and it's not bad

My GUI Miner lists f60, but I may have been running f120 and not saved the configuration. My PC is fairly usable while mining, but it's just the AMD freezing bug that seems to take place. It happened once when I opened a wmv file in Windows Media Player and earlier with the Curse Client. Before I turned off hardware acceleration in Flash, it happened with YouTube, but luckily, my drivers just crashed rather than freezing my PC.

up to 21 minutes now, pretty much inline with the difficulty increase.

 

[hdfxst]

yeah 22 minutes and .45 btc if it goes below .35 i might stop mining

Youre looking at less than that after a full 24 hrs at the new difficulty.

 

[hdfxst]

I think tomorrow might be my last day of mining.I'm not going to add another video card and i don't want to clock my cards up to the max.and i just added a small 24 volt blower to the side of my case and it really dropped the temps of my cards,low to mid 60's and with the ac on i can get them into the upper 50's

I was thinking the same thing. I've gained ~12BTC in the past 20ish days, which is not so bad if you consider I played also, but with the current difficulty it doesn't look worthwhile to continue mining. I might leave the 6850 mining, since I bought it for this very reason and I'll check it every two-three days or so.

 

[hdfxst]

The increase in july was going to be the end of the road for me any way.i just don't see the point in beating up the hardware for the 2 coins a week i'll make.according to the calculator on deepbit's site you would have to run 750 Mhash/s to get .49 btc

 

[wbynum]

Definitely going to shut down the rig that has a single 5830 tomorrow. It burns around 300 watts and only makes .2 BTC per day, assuming no down time, 0% pool fee, etc. Assuming a BTC price of $15 it works out to about $2 profit per day after electricity. I think I would rather be gaming on the machine and not heating up the room.

I will leave the rest of my 3.8 gh/s farm mining through the current difficulty and then re-evaluate on the next bump.

 

[Dark Shroud]

If I didn't have the HD 5830 Extreme I would stop now. Anyway I really like the HD 5830's cooler. I compleatly understand why people are snatching these up.

Question, can anyone tell me if the HD 6900 cards need dummy plugs?

if your useing windows then yes need dummy plugs or monitors plugged in. if useing linux you dont

seems like the mining expansion has finally slowed down. Avg just a little over 6 blocks per hour, might not be as big of a difficulty jump next.
