I miss my Radeon's

Mine vanity addresses with them.

I see all of those 5xxx cards for sale, and I kinda wish I could put them to good use. Vanity mining is in my future, but it's not worth investing in.

I miss them too, I used to heat up the kitchen with one rig very nice.. now siting in the cold smokin' cigarettes

Vanitypool is nice, but it's not often worth more than Bitcoin mining. Currently I would lose money activating it (at ~$0.15/kWh) even with 90% PSU power efficiency and GPUs at 0.95V.

Clearly you're right: not worth investing in.

But that doesn't mean I can fool around with it once BTC mining becomes unprofitable. ;)

I wouldn't buy cards for it, but if you have cards running, it might worth looking into depending on your cost of electricity.

Is this thread from the futur? GPU mining is still profitable.

Yes it is. But we are counting the last weeks here...

I'm still mining away on my cards. Even though a few will be getting the first pre-orders, I don't think the majority of everyone will be getting theirs until January. Or at least, I'm not expecting mine until then.

It looks like I won't have to heat my small apartment this winter. I plan on using the rigs for LTC. Hopefully I can get about the same heat out of them.

LTC could be alternative. Too bad HD 7970 is not stable doing them, atleast ad far as i know.

Stop smoking cigarettes


Thanks for you to finally notice, I am from the future


That's interesting. I'd love to see what 7990 could do. or even if NVidia's next chips will be compatible

I'm gonna keep mining until I feel like stopping.  Free electricity for some work I do :)

They work okay, but they get about the same kh/s as 7950s.

I will keep mining, unlike others, I see the big picture and I'm in for the long run... so if I make 1 btc or 20 today, I don't really care...
worst case scenario I'm upping my electricity bill and lowering my heat bill so... maybe in 10 years when I have 10,000 - 15,000 BTC then BTC might be worth more than $10... :)

What if they're worth $0?

I wish I would have found bitcoin sooner. I'd love to have built up a massive 10+Gh/s mining farm! I always wanted to do this for Folding@home but could never come up with the funds to do so. Doing this a year or more ago would have paid for itself if bitcoin mining.As it is now, my 2.3Gh/s of GPUs will JUST pay for them selves by the end of the month.

I will say this - I'm looking forward to being able to shut some windows in next winter... If only asics arrive before then  :D

? That's completely false, I get 524 K-HASH 24/7 Stable.
If anything 7970 is one of the best for litecoin mining.
I am using reaper. Btw increasing the aggression above 13
lowers the hash rate I noticed this, though if you put it
as a second card, and a different card as main,
its possible to get higher aggression, and yield more hash rates.

Here are the settings:
(litecoin.conf)

host ltc.kattare.com
port 9332
user xxxxx
pass xxxxx

protocol litecoin

worksize 256
aggression 13
threads_per_gpu 1
sharethreads 16
lookup_gap 2
gpu_thread_concurrency 21000

MSI AFTERBURNER:

Core Voltage (mV):   1049 from 1174
Core clock (MHz) :    1000
Memory Clock (MHz): 1375
Fan speed: 54%
7970 Temp: 84 C
-------------------------------
524 KHSAH Mining Rates:

Do note I found a article some where, don't remember, but they
state that AMD cards can run almost indefinitely at 90 degrees.
and their limiting temperature is around 105 degrees.



I even undervolted to 1049 from 1174, as well as overclocked.
Its a good card.

I really don't see the difference between having a GPU you could sell for $200 but choose not to in order to mine Litecoin/Vanity addresses, and investing $200 to purchase the same GPU for the same purpose. Either way you're giving up $200 in order to mine.

571 KHSAH Mining Rates:

Here's a more OC clocked version, its stable, though
I don't run it at this, as its too loud, 54%-60% it goes up 10X in sound.
But here it is

Try turning your core clock down and the aggression up, I get higher hashes on a 7770 with 915 core / 1360 mem and aggression 19

For some reason high core clocks result in not being able to use high aggressions

You should be able to do 915 core with 965 mV too

I think I'll miss GPU mining less than I won't miss GPU mining :)

Days of being excited to get new hardware, set up new miner rigs and watching my GH go up and up will be missed.

Days of trying to keep 40 GPU's running on 9 machines, 8000 BTU Air Conditioner still barely keeping the room at 95 degrees F, $800-$900 electric bills, crazy noise & heat, and tripping over extension cords won't be missed.

I agree 100%, it was a wild and crazy ride, that I enjoyed a lot; but I literally barely slept for months, it was like a dry-sauna 24/7 in my room, I'm pretty sure I permanently damaged my hearing from having so many fans running full blast, and trying to convince the people I lived with that the Feds were (probably) not going to break down our door searching for a "Grow" house due to power bills that could only be explained as normal if we were a 10 bedroom mansion in antarctica was a bit exhausting.

Lots of good stories and memories though, so that's something.

Yes, $200 = $200, but that isn't the only cost.

Cards don't show up at your door and start mining. You have to do some setup and probably play with clock speeds. If you've already done this for a card for BTC, transitioning the card to a new purpose is less work than setting up a brand new card.

if heater is gas that's much cheaper than heating via gpu

I'll keep mining with my GPU, until 30M diff or so, cause I'm in for the long, and truly beleive BTC will worth much more within few years..
If I had not lost my full time well paid job, be sure I had grab a bunch of those cheap GPU availlable..  :(  Those bastard, they fired me while on sick leave..  Enjoy Capitalism :P

Why not sell the GPUs and buy BTC instead? You'll end up ahead.

exactly. if you can't mine profitably don't go into the negatives just to get coins you think will be worth more later. take the USD and BUY the coins :)

Yeah.  Mining at a loss at any point is just stupid.  If you are paying out more than you are making from BTC, you would have been better to buy BTC straight up like the others have said.

Let's say it costs you $12 to make $10 worth of BTC, you have $10 worth of BTC.  If you had just spent that $12 on BTC, you'd have $12 worth of BTC. :)

Don't worry 420.  Your Radeon's are safe with me  ;D

yes, I hope

got 2.2g/hash yet?

???  ???  ???

That's part of a high risk investment... I understand other people mine to make quick profit since the cost (power)/ benefit (BTC price) gives them an edge... well....for me mining is a hobby as well as a long term investment. BTC is not my primary source of income, on the contrary, I spent close to $5000 in rigs, however, I already recovered the investment BTC wise, and I'm just keeping as many as possible...
I don't buy BTC, I just mine them... and in the future, they might worth 0, or we might be debating about the time we used to own a whole BTC!!! :)
we'll never know...

yes it is strange moving to just plug and play BTC mining. At least we have Litecoin to turn GPUs on to

Death, might I inquire as to what you are mining with to have that 10-15K mining number in your head?  That's 1,000 - 1,500 BTC a year.  Assuming absolutely no change in difficulty, that's about 10.5 GH/sec right now and will 21 GH/sec at the next difficulty change when reward drops to 25.  Then 42 GH/second 4 years from there, then 84 GH/sec 4 years from there.  Once again, assuming 0 change in difficulty, which is not going to happen.

maybe he's including trading bitcoin on the ups and downs to increase his supply...

Could be, he could have 100 GH running for all I know.  Just seems like there's a lot of people around lately that seem to think "My computer can makez me money for free? Sweet!  I'll mine with my Celeron e3300 and I'll be a bajillionaire in 5 years!"

I just hope new (and even some old) folks are taking some time to do a bit of research before they invest too much into mining and really understand the money that can be made vs. how much money they're spending on hardware and power.  Seeing some of the posts, I think there's a lot of confusion/misinformation that people are working off of.

A little bit of research and number crunching can relatively easily let you know if it's smarter for you to mine, not mine but buy BTC directly, or just avoid BTC altogether.  Smart/Informed decisions can be made about BTC if you're willing to put in a little bit of time.  I hate to sound like a crotchety old SoB, but there seems to have been a real uptick lately in people who don't see to have any clue what they're doing and there's no excuse for that, all the information is out there if you just look.

That's actually a decent point - which is why the best pro miners have sold their farms slowly over the last 3 months. Personally, I'm down to just my fpgas and the 6x 6990s on my gaming computers.

I'm actually looking forward to retiring those so people can have guilt free gaming again.


Asics are going to change up the game - but it will settle out in the long run... my advice is pick your price point (mine's about $10/btc) go short as soon as an asic ships or you see the difficulty going up... There will definately be a couple of crashes as people generate 2 weeks of coins in a day or 3. Then when it gets 'low enough' buy buy buy.

I am still putting together GPU miners, call me crazy or whatever, that's up to you.

It is not for BTC though, they will all be mining alt coins. Think of it as a long term investment.

GPUs will not be useless for mining after the reward half, they will only be useless for BTC mining.

The number is not in my head...;) mind you it was way easier to mine when btc came around and i've been successfull buying and selling also.

I stopped GPU mining a while ago.  The electricity generated from my solar PV panels is worth more when exported rather than used to generate bitcoins.

I am still mining, I just wish the Asics would be released later rather than sooner, perhaps next summer. That way, I could get more of my ROI from my cards and use my rig as a heater in the winter XD.

IDK, I did all of my mining gear on an extreme budget, minus my 6970 which was bough for gaming, just serves double duty is all.

For example one rig is:



Picked up a couple 5830s as well for ~$70 (this was back in Feb 2012).  

All in all, all the mining gear has already provided me 100% ROI.  If I keep the gear when done, I made cash and got "free" hardware.  I'll likely sell off most of it.  Will probably keep the atom (reuse as a Home server / VPN server) and one of the 5830s for my HTPC (i3-2100) so it can do some decent gaming.

amen to that lol. save some money on actual heat bills

Haha yeah, I actually made my rig during the summer, had to deal with my room getting hot as heck because I use my rig as my daily computer. ASICs, Y U NO GET RELEASED IN THE SUMMER???
