Hello...

Im new here, have been mining for about a week now, and managed 4 bit coins as part of a pool. At today's rates that is about £40 per week, or £173 a month.

Anyway, im thinking of selling the card I have been using and upgrading to 2 x 6870's or 6970's maybe.

The card is a 5870 factory overclocked to 950Mhz.
Here is a link to show you what card it is:
http://www.powercolor.com/Global/products_features.asp?id=245

The card is in almost brand new condition, having hardly being used up till now, until I found out about bitcoin and tried it out to see how fast I could make bitcoins.

If you run the miner with the fan on auto, it ends up getting up to about 60% fan and about 70 deg C, so I turn the fan up to 100% manually and is stays around 58 - 62 deg C on 98% load.

At the standard overclocked speed, it runs at about 393 Mhash. I tried overclocking it more, for a short time, and took it up to 1010 at which point it was running fine at 415 Mhash. I didnt really dare take it any higher as it is running on air cooling, and didnt want to leave it running at this speed for long, so left it 10 minutes to check it was stable, then put it back to 950Mhz and left it at that.

If no one wants the card for a mining rig, then ill stick it on e-bay, so send me a message if you're interested. Im in the UK by the way, so shipping within the UK will be fairly cheap, outside the UK might be more expensive, I dont know without getting a quote.

I can happily provide any screen shots, photos, videos etc etc to provide proof of speed, noise levels, temperatures, condition of the card, whatever you like.

Oh, and I didnt mention before, and have just noticed that the photos on the Powercolor website dont show this:

The card come standard with a huge copper heat sink and copper cooling pipes, with a large fan on top, meaning that it is very quiet compared to the standard heatsinks with tiny little fans.

Also - new the card cost £320. There is another one being sold on e-bay at the moment for £170. That one is not mine, so if someone wanted 2 of them for crossfire, there is another one to buy out there - these cards are very rare and were very limited at the time they were sold.

hey and welcome to the forums.

there will prob be people interested around. as the 5870 is a solid card.

one thing people might want to know is will you accept bitcoins and how much.

tbh I am considering it but I think my GF might kill me if another card comes this week.

Well, yes I will accept bit coins, however, like I said, I have only just started mining and learning about bit coin, so I dont know enough to tell you how many bit coins I think it is worth.

Preferably, I would prefer payment in ££ though as I will be using the cash to part fund the 2 x 6970's (though I have just seen today that the 6870 and 6970 is not as efficient as th 5870 and I dont know why yet).

Just further to my original post, I have just got home from work, and taken the screen shots posted below after having bitcoin running all day to show the temps and hash rates etc.
You can see GPU temp at 60 deg C and max of 63 deg C - at the top it shows it has been running for over 11 hours.

cards seem damm overpriced on ebay. I know where I can pick up new 5870 for around £120. If it was not for ebay taking 10% and listing fees plus paypal fees I would of considered buying and selling them

As your new to mining I will give some advice. Dont get 6970s get 6950s as you can unlock the shaders and make them to 6970s.

plus you know 6970s are going to give you about the same output as your current card. 6970s are £190atm and 6950s are £142atm. so you can save 100 quid there.

If your upgrading just for mining might as well get another card and stick it along side what you have got. Unless you plan to use your mining to fund your gaming Smiley then UPGRADE Smiley

a bit off topic but where about's in the uk are ya. Newcastle ere

Well, yea, you can get a new 5870 here (see below) for £146. This one is an 850 Mhz card though with a std heat sink. The one im selling is factory OC to 950Mhz and it will overclock (via CCC so no voltage uplift or anything) to 1010Mhz. Not bad really.

Hmm...well, I may be wrong then, because it was the dual core one I was after, and 2 of them, but for games mainly, not mining, though that will be a spare time thing like it is now. I think I may be talking about the 6990 or something? I dont know a huge amount about these cards, just that I want the best games card out there.

Im near Leeds in the UK btw.

aye will be the 6990. Its because ATI moved all the damm numbers around from the 5xxx and the 6xxx confused everyone. must admit even tho the 6990s are nice I would not want to pay £600 for one card. can set up another full mining rig for that.

Well, yeah they are about £500 each, but like I say, they are more for games than mining.

2 of those and it will demolish BF3 and Rage when they come out  Grin

With the same card?

There must be some difference, maybe a more efficient miner, or different extra flags?

You could try my modified phatk kernel with Phoenix 1.5:
http://forum.bitcoin.org/index.php?topic=25135.0

Flags:
-k phatk AGGRESSION=12 BFI_INT FASTLOOP=false VECTORS WORKSIZE=128

Phatk seems to be better suited for 58XX cards!
