Not really looking to ship outside the US.  Thank you for your interest though!

Two basically brand new HIS HD 5770's, in box.  I'm looking for $75 a piece.  





**Someone tried to purchase, he is trying to work through it through paypal, we'll see if it goes though.

**Buyer was able to fix issues with Paypal. 

50btc is WAY overpriced for a dying game.  What server are they on?  If they aren't on a good raiding server, gotta pay to transfer....also are they crafters?  Muters?  Tinkerers?  Lvls of those skills?  How many quests done?  I could level a char to 90/250 in 5 days played time easy....it's all the little stuff that makes an account worth something.  Also, how long has the account been active?  Do you have all verteran rewards available?  Too many questions left unanswered to warrent 50btc.  I'd say account is worth $100 tops. 

yeah 3 hrs...that's rough.

I happen to have an HTC Evo 4g that works like a dream but has a crack in the screen.  I bought a new one to replace it, and it's just sitting on the side.  I have the box, manuals, cables, extended batter, extended battery cover, the whole nine yards.  Has a screen protector on it, so it is holding the crack in place.  PM me if interested.

I have about 420 mh/s available for lease if you'd like.  I'd say $60 a week if you'd like.  Currently I'm pulling in ~4BTC a week.  Let me know if this is something you'd be interested in.

Also if you look at the newegg site review:

You'll see that there is only 1x PCI E x16 slot on the board.  Might be that you don't have 2x PCI E x16.

Taken from the Asus website regarding your board:

Expansion Slots
1 x PCIe 2.0 x16 (single at x16)
1 x PCI Express 2.0 x16 slots (@x4 mode, 2.5GT/s, black slot)
3 x PCI Express 2.0 x1 (2.5GT/s, gray slots)
2 x PCI
* The second PCIe x16 slot (black) and the three PCIe x1 slots share the bandwidth from the Intel® PCH. When any of the PCIe x1 slots is occupied, the second PCIe x16 slot will be switched to x1 mode.

Do you have anything in the PCI E x1 slots?  Try taking that out to see if it makes a difference? 

Solo miner, running 440 mh/s, ran solo for a while, realized I would basically never find a block, switch to pool mining.  That is where it's at.  Especially with difficulty increases and the increase in hashing power it's better to join a pool.  I'm part of Slush's pool, http://mining.bitcoin.cz and have had really good luck in there so far.  Have not found any blocks, but have made some bit coins, and at a rate greater than what it claims I should find a block myself. 

My specs:
2x HD 5770's
Guiminer
Running 970/300 on each
220 mh/s per card

Install MSI Afterburner, and underclock your RAM down to 300 mhz.  Make the fan speed 100%, and try taking the side of your case off.  Typically this will reduce the temp of the card by 15 to 20 C right there.  Also, if you have other cards that are near your vid card, like sound cards / tv tuners and such will make the card warmer just being near it and not letting the heat escape.  Try punching out extra metal covers in the back of your case as well to allow increased air flow.  One last thing, take a desk fan, and blow it directly into the computer, this is usually good for a 5 to 7 C lowering as well.  I run my 5770 at 970/300 and the temp never is higher than 70C, usually at 68C.

I run 2x 5770's at 970/300 each.

Each one is running 215 mh/s.

I use guiminer with -v -w 256

I use MSI afterburner, and made sure to set my fan speed to 100% all the time.

I changed the voltage up to 1174.


After all of these changes, my cards run around 67 C, are very stable, and I've had no issues what so ever.  It seems as though I get a lot of artifacts on my screens if I bump to 1000 mhz, and if I run the core clock at 1k for too long, my compy will crash.  970 seems very stable and it has been running this way for weeks.  I would be more than happy to help anyone get set up with their 5770's. 

I have not received any yet, but I have sent a few because people helped out with answers to my vid card questions, or to Jade for his awesome Widget.  If you haven't seen it, check it here http://forum.bitcoin.org/index.php?topic=14307

I'm hoping that I can help someone someday and they will return the favor.  Even 0.01 BTC is enough to say "thanks for your help"

Hey slush, is your API address going to change from the mining.bitcoin.cz address, or will it stay the same?  Just a curious question.

@Robert

He's using both addresses, and if you check out slushs API code, it does tell you to use mining.bitcoin.cz.  He actually has an SSL cert on there, and wants you to use https, but since he had to switch hosting companies (i believe it was hosting companies), the SSL cert hasn't been verified and is giving an error. 

I actually did some testing on this, and found that in the sub ~600 mh/s range it is better to use PPS than it is to use proportional.  If you are running around the 600 mh/s range, you are around 2% of the total hash power.  If you are finding say 150 shares out of 2,708,361 total shares, your proportion of that block is 0.00003582 btc.  Where as if you multiple .000051298 btc X 100, you'd receive .0051298 btc, or 143% more btc for the same timeframe. 

For my tests, I ran this on two different computers, running the same hardware (hd 5770's) over the same 24 hour periods, one with proportion, and one with pay per share. 


And now as I'm typing this, I've now seen that I just hit 3 shares out of 1,405,030 total shares, and my proportion of that block was 0.00010356 btc, which is like 3x the previous example.  So, throw that out the window.  Thought I was being helpful, and then that threw me for a loop.  I'll try to add some figures up in excel and let you know what I come up with too.

After looking into your file gadget.js, could you please fix this line of code?


to this:


Simply remove the "2" from Slush's address to properly gain JSON stats from his server.  Thanks for your good work Jade!

Hello all!  I'd like to have access if possible.  First, I need some help on my HD 5770 outside of what's on the boards already (i've read a number of the posts regarding over/underclocking the 5770's), and I'd like to converse with Jade about his windows gadget he created and just recently updated. 

Thanks in advance!!

-Phewajack

But now you won't tell me where you mine so I can't come and steal some of your profits!!  Sounds like a true BTC miner!

Thanks w0mbat, can you give me any advice on slush's pool?  It's the one I started using.
