Cryptocoin Mining?

[Zargon]

at 4 bucks im almost tempted to turn my 5870 back on at ~420mhash

 

[dakU7]

Difficulty level is still high for 4$ for me.

 

[Idontcare]

I sold 126 coins at $3.10, about 1.5 weeks ago, real ticked now that they went up to $4.60 a pop

Why did you sell at <$4 when your plan was to buy up a ton of them if they ever got that cheap?

If coins drop below $4, then yes that would be the case. If that does happen, I plan on buying up a ton.

 

[j&j]

i'm sitting on ~300 coins, still mining at 4000mhash/s right now. i'm just purely gambling that there will be an uptick once again. I plan to ride it out till spring and it gets warm again. if the difficulty can stay where it is i'm making a tiny profit a $4/coin, but if by chance we a spike to 10,15,etc. i'll be a campy happer.

 

[Magic Carpet]

No point to start now, I see. Good luck with your bets, miners ;-p

better hang on to your cypress and caymans, tahiti is roughly on par with 6970 in bitcoin hashing.

Interesting. I thought it would do better, apparently not much.

While I wouldn't my breath, it could get better. 5 and 6 series performance wasn't as good as it is now originally, it took several improvements and additions to the mining software to get where we are. There may be some missing optimization in play here.

That said, you would be insane to go and buy a 7970 just to mine bitcoins.

I bought 100 of them when they were $2.90, then they dropped down to $2.15 right afterward so when they reached $3.10, it seemed like a good time to sell

Bitcoin mining likes as many alus/cores as possible. The 7970 has 2048 which isn't a huge upgrade from the 6970's 1536 alus or the 5870's 1600 alus.

It's not really how many cores you have, it's the microarchitecture that most dictates what your performance is going to be. VLIW5 was very good at hashing, but was not a good general-performance GPGPU architecture. GCN, on the other hand, was designed from the ground up to be a more generalized architechure. Which reduces performance in certain tasks, (like hashing) but increases performance dramatically in just about everything else.

I'm glad Tahiti doesn't bitcoin mine well. This means my 5870 retains its value to you weirdos so I can upgrade to a 7950.

I was talking about strictly bitcoin mining performance. Of course GCN is better at most GPGPU applications as that was one of its main focuses. No doubt that GCN is going to be better at more tasks than VLIW5 and VLIW4.

Define tiny. My cost is about $1.90 per coin, so I'm happy that it regularly spikes to ~$3.00 or so.

 

[Smartazz]

I calculated that it costs less than a dollar for me to mine a bitcoin. 4x your cost is a pretty good profit. Any idea how this would affect video card life if the GPU runs at 55C? That is pretty cool for a video card.

55C is really nothing, most of my mining rigs were running at 80C+ 24/7 for several weeks without issue back when the BTC were worth more. That said, maybe I've taken years of life from my 5830s in that time span, but I'm pretty sure 55C would be as safe as houses.

 

[Smartazz]

Interesting to see a bunch of miners coming back online. 8.5THashes/Sec, difficulty is set to rise too.

 

[Magic Carpet]

Last price: $4.75000

Going up slowly.

-ROUND 2-

Who's getting a 7970 for mining? :biggrin:

Why on earth would you do that? $500+ for the same BTC performance as a $350 6970 (or worse, $250 unlocked 6950 or less than that for a 5870).

The world is full of weird people? ;-p

I am set on gaming, mostly. No way in hell, I am paying this $ for it. There are ways to get it cheaper, though.

2) I haven't owned a top card since 7900GT days.

 

[sandorski]

Thought of putting my 5870 to work to buy a 7970, but after seeing BC results I changed my mind. Probably will still do some Mining and spending on something else though.

You just break even?

 

[Dark Shroud]

I'll buy a 7900 card for gaming and retire my 6970 to Bitcoins.

The 7970 is slightly better, 20-30% IIRC, not enough to spend $5xx on IMO. If it was 60%+ I'd be more tempted.

Sorry, I meant your bitcoin career
