As in Mining. 

Gaming is not a concern for me.  I was simply wondering if the 7970 and 5850 would mine together without hanging or crashing the system.
342  Bitcoin / Hardware / Re: Bandwidth required for FPGA mining. on: May 21, 2012, 09:21:47 PM
Well from my own 50M/hash miner I deduced it was at least a few megabytes per hour, but I do have other processes going.

Just wondered if anyone had some actual stats, as my upstream is limited to 40-50Kbytes a second, I dont want my upstream to limit the amount of work I can process.

kind regards

It's fine.  Bitcoin mining does not use much bandwidth at all.  The amount it uses is not a concern with those speeds, and especially if you are not charged for how much data you use or caps by the ISP.

Hello,

I have ordered a 7970 and I am currently awaiting for it to arrive. I also have a 5850 that I currently have already. 

My simple question is, will there be any compatibility issues?

Just sent you the 0.4 BTC.

Awaiting for PM of code  Smiley

You have PM. Enjoy the game!


Vouch! Went smooth and fast.  Thank you for the code Smiley

Just redeemed it and is 100% working and unused.

Ok, my address is 1cAjvxanFKCghvT9vSUhuqiUZTLWfddJg

Which one should I send the 0.4 BTC to?

I'm interested.  Please PM me with the steps needed for transaction

Electricity is only $0.03/kWh

Heh, that's nearly free.  Yes, that gives you an advantage over competitors for Bitcoin mining then.    Where is this?, ... that's really, really low!

With that low of an electric rate, you'ld probably be better off getting some used GPU hardware now and start mining now than waiting for an FPGA (in a purely financial sense).

My main worries is, what will happen when the block reward halves? Shouldn't the exchange value rise in compensation due to a decrease in supply?

It's not a surprise though to most speculators, so it may already be priced into the current exchange rate.

Additionally, it could be the event that many GPU miners are holding out for and when it occurs, they will dump their GPUs for bitcoins and spend their hoard of bitcoins on new hardware, whatever that hardware at the time happens to be (new FPGA design, or ASIC, or whatever).   That might put as much downward pressure on the price as the lower new supply (3,600 BTC fewer issued, per-day) would cause.

Can you recommend any cards? My current PC has only 2 PCI-e slots (actually 3, but the 3rd is a bit slow) and I have around $600 to spend.

Or should I just build a fresh PC that is dedicated to mining?

With the 25 BTC halving coming in December 2013, or possible market crashes/fluctuations, is there any concern to the failure to recoup my investment?


December 2012.  Like in 7 months.

Mining is competitive.  In a competition there are certain properties that will favor one competitor over another.    With Bitcoin mining, there are three main properties that matter:

 1.) How much does your electricity cost.  Right now the breakeven for GPU mining is about $0.20 per kWh.  With FPGA mining, the breakeven drops significantly but the upfront capital cost is nearly double.  (i.e., a $500 GPU with $0.15 per kWh electricity might pay for itself sooner than a $500 FPGA at $0.10 per kWh will).
 2.) Capital spent on FPGA mining is speculation regarding future unknowns.  It is an asset with little market value other than for mining.  So if there is a technological advancement with a big jump in efficiency (e.g., ASIC) that would cause difficulty to rise faster than the exchange rate and thus it would mean that you cannot mine profitably using an FPGA.  You would then have paid a lot of money for what ends up being an expensive book-end.  Is that capital still available even after being aware of the risk (or are there other places with better return or less risk than mining for it?)
 3.) Technical skills of the operator and capacity to learn and administer a mining operation.


Electricity is only $0.03/kWh

Also, putting the 5850 into equation along with the BFL would mean I am producing

347 Mhash/s + 832 Mhash/s = 1,179 Mhash/s

~$3 a day at this time

My main worries is, what will happen when the block reward halves? Shouldn't the exchange value rise in compensation due to a decrease in supply?

Hello,

I am attempting to start a true mining investment in bitcoins.  Currently I am mining with a single 5850 and would like to start out with a real money making model to make some small cash.

With the 25 BTC halving coming in December 2013, or possible market crashes/fluctuations, is there any concern to the failure to recoup my investment?

The wait time for these units is quite long, at 60 days, so this is something I am worried about.

Or should I go ahead and borrow money from my parents(Yes they are lending me some, I have all my money deposited for College) and go ahead with the mining?

Maybe I am worrying too much?

Thank you,

Aqrulesms

I'd say go College first Smiley

Starting to sound like my parents.  Cool

Any serious answers?  Grin

I pay .0208/KWh in the northwest. The heat from gpu's is the biggest issue around here.

I am limited by the maximum power available to use electrically and then dissipate thermally. This is also my main logistical limitation.

What I do is just put the rig in the garage, open the back door and let the heat flow outside, while still protecting the rig from the elements.

Although I have only one 5850 it is quite profitable here in Austin, Texas too.

Electricity is CHEAP $0.0355/KWh

Even with current difficulty levels I have a pretty reasonable profit. (Around 80% efficiency)

I'm interested in buying the fake Dr. Dre tours.

How many do you have in stock?

I updated the original post with what i have. Check it out!

Ok, thank you very much!

I don't have enough bitcoins after recent spending and am currently mining for more. ETA 10 days :|

Amazing.  Switched over from Deepbit.  This pays more and is overall much better.  I love the client too! Smiley

Thank you for such an amazing pool.

I currently have a converted gaming rig that I am currently using for mining. It is currently running a 5850 at 300 mh/s at stock speed without OC, as I want to make sure my card has a fair longevity.

Here's a good starting point: I have two Sapphire 5850's@400MH/s each.They are running on 12.1 drivers with SDK 2.5 from the 11.11 drivers (SDK 2.5.793.1). I'm using cgminer with phatk kernel, vectors 2 and worksize 256; the cards are clocked at 970MHz core and 150MHz mems. I have auto-temp set at 70ºC (for "longevity"), the fan usually goes between 54-58% to achieve that.
are you overvolting? I don't think it's possible to get 400 MH with stock voltage.

Nope, stock voltage.

with 12.1/SDK 2.5 my sapphire 5850 gets 395MH/s
930 core 180 mem 1.088v
fan 50% 60c

What OC tool are you using?
358  Other / Beginners & Help / Re: Buying another 5850 for crossfireX, want advice. on: February 27, 2012, 09:59:36 PM
PS3s cannot run unsigned code. It leads me to the conclusion that the mining script only works for jailbroken PS3s.

Is that correct?


359  Other / CPU/GPU Bitcoin mining hardware / Re: GPU chip degradation on: February 27, 2012, 01:45:02 AM
Do the effects of electromigration progress over time or is it just an instant thing where the card simply gives up after running great immediately before the total cut in the interconnectors?

If not, I believe it may be your own configuration issues with the drivers, OC, and etc.

Does the card still function fine at stock values?

Despite that, the card does draw more power, and would lead to accelerated electromigration. The connections within the chip themselves would wear out and become "thin".

How long have you ran your cards at those configurations?
