Just proposing an idea I've just had. Basically, I live in student accommodation, and everything is included in my rent. Would people be interested in co-locating a rig or two? I live in Nottingham, and this is something that I would be able to do for the next 6 months.

The accommodation I live in is private, so there's no intrusion by university staff. I'm a Computer Science student, and I used to mine myself before I had to sell my rigs to purchase a laptop for university. If this is something that you might be interested in then please feel free to drop me a message and we can discuss prices.

I have two 5870s and I'm having troubles getting them running together. When the second miner is running on its own it runs fine, but once I start the first miner the MHash/s of the second card drops to about 15. This only happened when I reinstalled Ubuntu 11.04 for a client and I can't figure out why it's doing this.

Does anyone have any idea?

Hi there,

I've recently started offering mining contracts, and I want a website that tells my clients how long their rig has been up. I'm not really sure how to go about doing this, but I'm willing to put up some BTC for someone that knows how to. I have a hosting account with everything you would need to get started. For the time being, it only needs to be simple (Username and password login, how long the service has been running) and be open for expansion in the future.

Features -

*Client login - Tells them up-time, how long they've got left on their contract, next payment due
*Admin login - Shows all the users, possibility to add time to their accounts, see payments etc

As I said, I don't really know what I'm doing here, embarrassingly I'm going to study computer science in the autumn, but I just don't have time to work on this right now and I want to get it up and running ASAP

So I noticed on my Android phone that my Google account had been signed out - I attempted to log in on my PC and it was also signed out there, my password wouldn't work either. It's not like my password was simple, gufegd characters in total, non-dictionary word.

Is this a direct result of my account details being leaked? I can't remember if I used my simple "I don't care if it's leaked" password for Gox (I don't use it to trade, just signed up to it when I first started BitCoins) or my harder password.

I am trying to figure out how to get my miners to autostart once Ubuntu logs in. Every time I restart, I need to open up AMDOverdriveCtrl for each card and then open up terminals for each of my miners.

Is there any way I can put this together in a single script so that it opens new miners in separate windows, as well as opens up AMDOverdriveCtrl?

Edit; I'll tip what I can for a good solution!

Hi there

Basically, I have an XFX 5870 that is a little dodgy. The default idle clock speeds are too low 157 core, 300 memory meaning that when I attempt to mine, my whole system crashes and I get green artifacts all over the screen. In Windows, I can set a profile in the AMD Vision Centre (Rebranded CCC) to set the idle clocks higher so that the artifacts disappear and I don't crash.

The thing is that I want to mine in Ubuntu but I can't figure out how to change the idle clock speeds. Does anyone know how to do this? The option isn't there in CCC like it is in Windows. I also can't find the "Profiles" folder to edit the profile.

Hi there

I bought a new XFX 5870 1GB a few days ago and whenever I try to mine with it my whole computer locks up. The screen literally freezes and I have to restart my PC.

I had another XFX 5870 (which is now faulted too, but that's a different story) and that worked fine. I'm not running any extra flags, and I'm using the same settings as my previously working card of the same manufacturer.

My GPU idles at 157mhz core and 300mhz memory. There's also a number of green pixels on my screen, which seem to appear randomly, more so when the graphics card has to do something, like in a game, or attempting to mine. It seems that maybe the card is limited because games lag like crazy (and shouldn't on a 5870) and since mining takes the GPU from 0-100% immediately, I'm thinking that it has trouble adjusting and just locks up.

Any suggestions on what's going on here?

Hey guys, having a little issue, maybe someone knows what's wrong. I've been mining fine for the last couple of days under Windows using a single 5870. Today my second 5870 was delivered and I decided to use Ubuntu. I can get my first card running perfectly fine, but the second card either crashes my computer or runs at very low khash/s

I followed the Ubuntu 11.04 guide and I can get my first GPU to mine perfectly, but if I change the device to -d2 (from d1, I've confirmed that the second GPU is d2) it either doesn't display anything and the terminal crashes, or it'll display a 653khash/s or so.

Does anyone know what's wrong with this?

I've maxed out my computers 2 PCI-E slots right now, so my next step will be building a whole new rig with a couple of 5870s. I want to cut down the costs as much as I can (Parts are relatively expensive in the UK) so I'm thinking of going for a caseless setup, with just the motherboard and relevant components on top of a surface.

Is anyone doing this at the moment? I've seen the guy on YouTube go caseless and he doesn't seem to have any extra cooling. The UK's quite cold at the moment, and it doesn't get nearly as hot over here as it does in other countries during the summer (Which will hit fully in a couple of months).

So I got my 5870 yesterday and I've had it going in Deepbit for a day (Previously had a 560Ti, just wasn't cutting it).

After reading the anti-Deepbit threads I've decided to try it alone for a month. I've just ordered another 5870 to double my hashing power and at current difficulty levels, calculators tell me it'll take 10 days on average to generate my first block.

How do I know that I've not done something wrong? Poclbm is happily mining away with a speed of 370mhash/s so I assume it's doing something. With Deepbit I knew it was working because I could see the results by the hour, but how do I know this is working?

Basically, I've pitched the idea of investing into Bitcoin mining to my friend. He would provide the capital to build the PC, and I'd do everything else from there.

I'm thinking of loaning around £500-600 from him, and then building a rig and either...

a) Paying him back a fixed amount, I'm not sure how much is a reasonable about, £700/£750?

b) Giving him a percentage of the income from day 1, say 40 to 60%, again, i'm not sure how much is reasonable.

I would be paying the electricity costs and everything too, so paying him back a percentage of the income would need to take this into consideration.

Anyone have any suggestions?

I've just ordered a new 5870 and I will soon be selling my 560Ti and buying another 5870.

For the time being, is it possible to use both the ATi and the NVidia card?

If so, how will I go about doing it? Is it just a matter of running two instances of a miner, but changing the flags?

Is there any reason why this 5870 (http://www.amazon.co.uk/XFX-Radeon-HD-5870-DisplayPort/dp/tech-data/B0037YMWXO/ref=de_a_smtd) is so much cheaper than this 5870 (http://www.amazon.co.uk/Sapphire-HD5870-GDDR5-Graphics-Card/dp/tech-data/B0031HAVSA/ref=de_a_smtd)?

I have the Gigabyte 880GA-UD3H motherboard (http://www.overclockers.co.uk/showproduct.php?prodid=MB-280-GI&tool=5) and the board has CrossFire support apparently.

It has two PCI-E x16 slots, so will I still be able to efficiently run two 5870s? I've just ordered one of the cards, but I want to upgrade to another one in the future. Will the speed double (or almost double) or will it not increase by as much since it will be using an x16 (x4) slot?
