I got a question: Why did you choose this specific place of your body for the tatoo?

Айде наште, юруш на кирките.

The setup in the signature = 0.800kWh = 19.2kWh a day x 0.10306p = ~£2

So 1BTC costs £2 ($3.18) to produce

Uh, the ROI is negative in every case, so why would anyone buy a service from you?

You have to be extremely stupid to fall for this 

I bought an Energy Meter to see how much electricity my rig uses, so:

4x XFX 5870 @ 960Mhz Core & 300Mhz Memory
Gigabyte GA-770T-D3L
AMD Athlon II X2 250
2GB 1333MHz DDR3
USB Flash Drive
3x CM Sickleflow @ 2000rpm
===================================
800-815W from the Socket depending on the time of the day
830W Peak

So the components use around 730W when the efficiency of the PSU is taken into account.

Same here. With the previous version my average was 1758 and now it is 1756.

This is for 4x 5870 @ 960Mhz Core & 300Mhz Memory
SDK 2.1
Ubuntu 32bit

Thanks for your replies.

It looks like I won't be building these as I don't have a place to put them apart from my flat, which will be very inconvenient

So currently I have a dedicated mining rig sitting in the corridor of my flat and being just 3.6m away from where I lay my head to sleep with one door in between.

1 - I'm curious what will be the subjective noise level increase if I add one more machine emitting the same level of noise? Will there be any difference at all?
2 - What about with 3 rigs in total? Will I notice a significant increase in noise levels compared to just 1 rig?

The weather in the UK is pretty good for mining even in the summer with daily temperatures being in the 20C region at the moment
3 - Would 3 rigs create much more heat compared to one? If there is some air flow created by opened windows at 2 ends and the air temps in the premises are 25C is it reasonable to expect 30+ with 3 rigs?

Thank you.

I wouldn't recommend you keep your cards at constant 90°, not even 85°. Try to be below 80°.

I got a question about security: how safe is my password? Let's imagine someone manages to steal your DB or whatever stores the user passwords. How difficult would be for that person to crack my password which looks like: TIzWU92Fn43K8CmYVclq

I get 440Mhash/s at 960Mhz Core, so you might want to try and tweak it further.

It all depends on your local market GPU prices, but in general: 5850, 5870, 5970 and 6990 are good, but then again it depends how much you can buy them for.

Yes, I got mine @ 300Mhz, but have no data for the power consumption decrease. Probably not much to have a profound effect on the power bill.

Ok, you will satisfy your curiosity and find what is the maximum stable clock for mining, but is it worth it apart from that? Probably not.

A quick comparison: mine are @ 960Mhz Core = 440Mhash/s, so you get 35Mhash/s more = 0.6BTC more a month than me for the much higher chance that your card will die much sooner than mine. What about electricity?

I got 4x XFX 5870 @ 960Mhz Core & 300Mhz Memory + cheap mobo and cpu + flash drive to boot Ubuntu from all powered from Corsair HX850

So 1000W is more than enough for 4x 5850.

Power consumption is less, but not a significant difference.

Have you installed screen? - sudo apt-get install screen

And always use sudo to make sure everything runs with elevated privileges.

Self Adhesive Neoprene Rubber Strip - to absorb vibrations

Use GPU-Z to export the BIOS from the card and then load it in RBE to check on the fans curve

Or you can get a BIOS from techpowerup website.

So can I expect any problems mixing 5850/5870/5970/6990 on the same motherboard under Ubuntu?

Would it make any difference which cards I mix or some go better with others? Best combinations in terms of less issues?
