1  Alternate cryptocurrencies / Altcoin Discussion / Re: How profitable is GPU mining? Recovering hardware cost seems take a long time! on: March 04, 2014, 05:57:44 AM
I have running number and it seems like it would take at least 240 days to 365 days (1 year)+ to recoup the hardware costs. Sad Seems like it would take till the 2nd year to actually start making any money. However, difficulty of all the coins should be going up by then and reducing profits?

How profitable is GPU mining? Are you guys making any money mining on Alt Currencies on GPUs?

Note for my calculations I was estimated 5,600 Kh/s with 7* R9 290 @ 800 kh/s with cost of $4,700 for hardware.
in january, GPU mining was profitable for me after 110 days.  

GPU mining in november when i started was profitable after 90 days.

you need to control your costs. buy your cards strategically and at better prices.

You also haven't discussed what your investment strategy will be.  I am looking to break even on hardware fast, and then hold for a long term (10+ year) investment.  my outlook is different from someone who would invest for short term profit.  your investment strategy changes how you interpret the breakeven point.

I think if i was just starting out, i wouldn't spend that much money with a 240-365 day breakeven.  in 365 days the market will be completely different than it is now.  hell, march doesn't even resemble january.  doing a cryptomarket forecast that looks a year in the future will need to account for new GPU tech, new currencies, new regulations, changing geopolitics and the emergence of ASIC miners.  that's just for starters.

however, everyone is in a different financial state and we all have different investment goals.  whether you should mine or not is dependent on a lot of factors.  honestly i would only use money i had in hand (i.e. no credit), and only use money i could afford to lose.  

So, are you mining and "holding" the currencies you have mined? The fluctuations in currencies seem so high, when you sell/buy them makes big difference on the profit.

I actually started out mining using single 2-3 year old GPU I had for gaming in Jan. 2014. There was one point in Jan/Feb it seemed like I was making $5 to $7 in profit (after electricity cost) with that single GPU. Thats when I started to get really excited about possible GPU mining in the future. However, since then recent prices+difficulty is putting me at $0.60 in profit with same card Sad I am hoping it will get better.

So I have been seriously considering getting to a GPU mining rig for alternate currencies like DOGE, VERT, or LTC. Honestly, I know there a lot of ALT coin miner and I bet they wouldn't be mining unless they actually made some $$$.

I have running number and it seems like it would take at least 240 days to 365 days (1 year)+ to recoup the hardware costs. Sad Seems like it would take till the 2nd year to actually start making any money. However, difficulty of all the coins should be going up by then and reducing profits?

3  Alternate cryptocurrencies / Mining (Altcoins) / Power Supply causing GPU+System Crash? How much power do I need?? on: February 22, 2014, 03:35:09 AM
I think I have problem with my power supply not giving enough juice for possibly even 2 GPUs (I have 3 GPUs). I currently have a Corsiar RM 850W with +12V at 70 AMP (~850W) on that rail.

I have 3 cards:

Sapphire Radeon R9 280x
MSI Gaming R9 280x
XFX R9 290x R9-290A-ENFC

#1 Test -> The power usage according to my Belkin monitor goes to near 800+w and which I believe eventually causes my system to crash (< 15 minutes).

#2 Test -> I have tried to lower it down to ONLY 2 of the 280x. This time the Belkin monitor goes to around 650w and then my system crashes in less than 15 minutes. I would think the RM 850w is enough for this at least?!  Angry

#3 Test _.Anyhow, I am currently down to test using only ONE 280x. The total watts usage is at 335watts and the system is running over 15 mins. I will keep on testing this.


So my question is does my Corsair RM 850w PSU just suck? Does it seem like cause of #1 and #2 test failing?

Finally, what power supply (or additional PSU) can I get for my rig? How much wattage and 12v amp on the rails do I need?

Thanks in advance! Smiley

5  Alternate cryptocurrencies / Mining (Altcoins) / Re: [ANN][YAC] Yacminer GPU miner for Yacoin on: January 21, 2014, 06:12:27 AM
I have having trouble getting YACminer to a profitable hashrate compared to other coins like DOGECOIN.

I have a Radeon HD 6850 and am getting 0.750 Kh/s at best without much hardware error. I am using the following settings:

yacminer --scrypt --scrypt --worksize 64 --lookup-gap 2 -I 8 --thread-concurrency 8192 --temp-cutoff 95 --temp-overheat 90 --temp-target 75


Any suggestion on how to increase my hashrate would be great. Otherwise mining, Yacoin doesn't seem that profitable to me  Sad Thanks!
