One guy with 9 posts says it's true, while telling you to buy more BFL products, so it must be true.

Anyone who does business with BFL is a moron.  They have yet to ship anything substantial, and this Josh guy is a rager and a PR nightmare.  Amy's Bakery anyone?

BFL is a liability.  Anyone who throws money at them deserves to lose it. People who want to be involved in bitcoin should be looking for lows in bitcoin price and just buy and hold bitcoins rather than investing in a product that may or may not arrive, from a company with a less than stellar reputation.  If you want ASICs, look at having one of the DIY guys build you something when the Avalon chips get in, or buy the ASICMiner gear.  There is no reason to be held hostage by BFL anymore, people.

I use CGWatcher to monitor my CGMiner and restart it periodically/if one of the cards dies.

Probably a really bad idea because you'd have to convert everything to rack mount machines, pay to send them out there and to be installed, pay for them to run there, etc.  If you can find a run down office space, you are probably better off.  All the costs would nickel and dime your profits to death.

First of all, I assume you're using the default Phatk kernel in CGMiner.  Switch to Diablo.

When you say "I will not mine past 12," I don't get what you're saying.  12 intensity?  Mine anywhere from 9-14 with these.  I mine at 9 on two Gigabyte 7870OCs, and 14 on an MSI 7870.  

I get about 460Mhash on all 3.

2x Gigabyte:
Vcore = 1.275
Fan = 85%
Engine = 1220Mhz
Memory = 625Mhz
Intensity = 9
Kernel = Diablo

1x MSI:
Vcore = 1.275
Fan = 85%
Engine = 1240Mhz
memory = 625Mhz
Intensity = 14
Kernel = Diablo

I find power limit to make mining overclocks less stable if anything.  The card can go over 85c, it only matters what you have your different temperature thresholds set at it - but the lower the temperatures the better.  I try not to push past 70-75c.

If it's throttling it's because it failed being stable and crashed.  Adjust intensity and overclock settings down and try again.

I've noticed that in CGMiner my second card (GPU1), always seems to perform worse. 

On one rig I have a 6950 and 7870.  When the 6950 was alone, I was able to clock it at ~940Mhz core and it was rock solid stable.  Since I've paired it with the 7870, I'm unable to get it stable at the same voltage at anything higher than 880Mhz.

I now have a second rig with two identical 7870s in it that is having the same problem.  The second card, under GPU1, dies at overclocks that should be stable.  I realize there is variance from card to card at what is stable, but it shouldn't be a 40Mhz difference between identical cards?

Any advice?

Firstly, why not just use CGMiner?

Also, if your card dies at a certain unstable intensity/overclock it will often restart with secondary lower clock speeds and you will get almost nothing out of it.  My 7870s drop to around 25-40mhash from 460mhash when this happens.  Restart your computer.

There is no reason to expect this isn't a "hacker network".  Buy tons of coins, wait for price to be drive up and then sell tons of coins and DDOS the site.  People panic on other exchanges and start dumping coins, people get back on mtgox and all put sell orders in because they think they're losing everything and the market continues to spiral down.  Price hits a bottom, "hackers" buy it at a discount.  They just profited.

I am done with Mtgox after today.  For whatever reason they are a target, I assume because they claim to do 80% of all Bitcoin trades.  If I had my coins with another market I would actually be able to act and try to get in on some of this action.

If you want to mine for fun, solo mine and hope you hit the lottery.  What's the point of PPS if it isn't "for the money".  Why look for steady payouts?

Good thing you made a new topic to make fun of him. Riveting stuff.

Hi.

New to BTC mining, and just spent the last couple of days milking a 6950 and 7870 for combined average 825M/hash.  It got me kind of addicted, so now I'm grabbing 4 more 58xx cards, but I'm not going to be able to fit them.  So, I have to use risers.  What happens to performance when you rise a 1x slot for a bitcoin mining card?  Do you just use a 1x-16x riser to plug a 16x pcie card into a 1x slot, and a 16x to 16x to just "extend" that slot so you have room to place the video card elsewhere?

Thanks.
