I was mining in an commercial office last year (cubicle style). I had to close the door to the room and ambient temps went over 90F on most days.  One day it hit 123F in that room - was painful to walk in there.  Needless to say one of the newer 6950s I had died after just 3 months.

Eh aren't you mining in Siberia though?

Those temps look good but every single one of my cards goes over 80C when doing scrypt, even when undervolting the core.

It's not enough to just uninstall the old drivers.  You need to do a clean wipe or even reinstall of windows if you're not sure how to get the 2.5 SDK in there.

Any reason you don't sell both cards and try to pick up a cheap used 5770 or 6770?  It would double your hash and use 1/2 the power.

That's not true.  If I buy a 7970 3 months from now and mine BTC, even with my free electricity I would probably lose more resale value in the card then I would be able to generate in BTC value. Only with the recent BTC price run has GPU mining stayed alive, otherwise everybody would be on a different coin.

Only the idiots who mine at a loss would mine BTC rather than just buy it for cheaper than electricity costs.

The new boards are at least 1 week out according to Josh, so maybe they'll show up some time in June.




















I mean June 2013.  June 2014 is the redesigned case.

Well we know most of the people mining for BTC have a computer and are most likely to have one running to 24/7.

But don't bother nitpicking minor details when people like erk can't grasp that concept that BFL lost the 1st leg of the ASIC race.

Why don't you calculate the inferiority based on earnings.

Avalon Batch 1 initially make 0.15BTC/day/GH
BFL's 5GH will arrive in mid 2013 make 0.05BTC/day/GH

Or are you one of those mystical time travelers and find time dilation consequences immaterial?  Hey, is that your magic unicorn saddled over, what a noble stead!

erk you have your head up your ass.  I have a BFL single and I am the original owner.  Obviously at one point in time I believed in BFL - far more so than you did that I was willing to risk my money.  That device has paid for itself and in that aspect BFL was successful for me.  Everything since then has been a steaming pile of poo... much like your list.

If BFL actually made a miner that did 1GH/watt I would applaud them even if it was late to the game sine everything with mining is not all about greed and making money.  Sadly they're barely more efficient than Avalon who managed to put a higher density standalone device almost 6 months before BFL.  What have BFL's preorder customers gained by choosing BFL?  The opportunity to pay for a device via wire transfer is the only advantage BFL has had in all of this.  The failed at being first.  They failed at density - a SC Single will be less dense than a 85GH/s Avalon.  They pretty much failed at energy efficiency - one of their main selling points.  They failed at customer PR - Yifu may talk smack, but Josh's mouth would make most sailors cringe.  Perhaps BFL's website is better than Avalon - I'll give them that.

Seems OP is still recovering from 420

I'm still shaking...hold me

This.  Got my BFL refund long time ago and made back the loss by trading.  I hate trading but I would hate waiting for "soon" even more.

Not bad pricing.  About 1/3 cost of Avalon Batch 3 if you price BTC to $120

Good luck seeing the minirig in 2 months time though.  Jalapeno yes, MR ....

I believe Gox requires the full 6 confirms before it shows the BTC in your account.

Batch 3 took three days to sell out because everybody was uncertain on ROI. It's still up in the air.

If ASIC owners and buyers are having doubts about making back hardware costs what are GPU miners thinking?  I still have a few cards but as soon my Batch 3 units arrive I'm tossing all but a couple 7970s

Yes the upfront cost is only 3500BTC.  Assume it was just one buyer.  Would he get back the full mining return on 2800GH/s?  No, he gets back 85%.  So essentially he would need a 115% ROI more or less to break even since there's a maintenance fee.

Even if you overclock you're only looking at 3TH.

I'm not mocking your plan, just saying the numbers don't really compete with what's out there like burnin's offering as noted above.

Yes 10GH/s will get you 0.5BTC today and for the next 5 days, then 0.4 for 10 days, then 0.3 and so on.  It will have a head start but when it can only make 0.5 BTC to start off, when difficulty is 5x it will make only 0.1/day - one might be holding their breathe waiting for ROI.

I guess it all depends on whether you trust the network to lay low for a month.

3500 + 15% is roughly 4000 BTC

Assuming Avalon Batch 4 is 40BTC, why not just buy 100 Batch 4 units which should hash at 5000GH/s.  No need to cut your fingers or do any work other than setting them up.

Whoops I gave away my plan 

Vicus your new avatar is even creepier than the last one of the kid biting his fist.

Thanks for that 2nd pic.  Now I can't eat or sleep.
