No, its my main rig so I didn't bother with that. AMD overdrive also doesn't let me go below the stock 1000. It only lets me go more.

Yeah, that's not a blower. This is the 5870 that I have...

http://www.newegg.com/Product/Produc...82E16814150443

and here's my 6950...

http://www.newegg.com/Product/Produc...82E16814150518

I've been pondering getting another 6950, but the problem is that Crossfire really isn't that useful for me as I tend to use dual-monitors and last I knew, it would disable your second monitor when you're in a game. So, I'm not sure what I'd do with it after finishing other than selling it .

What I need to do is convince my brother to let me borrow the Sapphire 5870 that he bought in that nice $180 deal since I'm pretty sure he's not using it . (Don't ask me why he's not... I have no idea!)

No, I haven't yet. I was considering dropping the memory down and raising the GPU clock.

EDIT:

That's strange... my 5870 has a wide range for both GPU and RAM. Albeit, the most open end of the spectrum is on the low-end (I only have +50 and +100 available respectively).

My 6950 is actually very similar to what you're talking about as I cannot lower the RAM timings, and I can only raise the GPU to 840 (from 800).

To those people that said they only used an online wallet, you might want to download the actual Bitcoin Wallet and use that instead. Much more secure.

Also, it isn't pools DDoSing one another. Some outside party is doing the attacks.

I wonder what the motives could be?

They're actually not getting ddos'd. There's just thousands of people constantly refreshing status pages LOL

Let's say you have 80Gh sitting in your basement pumping away. You DDOS the major pools who are getting almost all blocks. Your 80Gh is then a much larger percentage of active processing and possibly could get alot more blocks..> That's what I think anyhow. Then there's also alot of bitcoin detractors floating around the internet who wish to harm it just to laugh at people's misfortune.

Well...if a pool goes down that lowers total hashrate which should theoretically lower the difficulty increase. Or...it could be the govt.

EDIT: No they are definitely getting attacked. Slush himself said so, and deepbit confirmed it as well. BTCguild did naturally go over capacity though.

But if something happens, you have a chance of losing everything, right?

Also, is this the wallet?

http://sourceforge.net/projects/bitcoin/

If so... why is a simple wallet using 10-20% of one of my CPU cores?

The wallet, as I understand it, you just download the main bitcoin program and it gives you a long letter and number string. This is your wallet address. You can then close it completely and use the mining program guiminer and connect to a pool.

So, yes that program at your link. I got a zip version so you don't have to install though. Seems like a new version is out and a zip version hasn't been made for it yet.

Here is the older version with zip available:

http://bitcoin.org/ is the official site and has all of the downloads.

You could just as easily lose everything with it on that site as well.

Yes, that is what I have and it appears to be performing extra processing in the background like it's just randomly working out some hashes on its own. There's a "blocks" number that continues to rise the entire time. I really don't appreciate having a core randomly being used up by something that I don't even know what it is :\.

The only danger I see is that a hacker may want to go after that "bitcoin bank" much more than it would want to mess with my own private setup, but I'd have to ensure my own hardware is stable enough.

it generates 100 keys for use later, my guess would be that's whats going on.
also it's p2p, so it's constantly talking with other dudes on the net.

Yeesh, room heating up with 400MH worth of energy being dumped into my living quarters. Fans loud too. Turning off for the night.

You have to download the entire block chain which may take several hours depending on your connection. That is what is causing the usage I'd guess. The client uses hardly any CPU usage at all.

There are ways to backup your personal wallet, I'd suggest looking into it.

Why do you even have to run the main bitclient for except to get your wallet address? Guiminer is the only thing you need to mine in a pool website?

I don't think it's required to keep it open, just set the threshold to something like 5-10 BTC and make sure you connect to the bitclient when you go over the threshold so you receive your payment.

My worker speed keeps dropping like crazy on BTCG because the client says it cannot communicate . Sigh... I'm only looking at getting a hundredth of a BTC this round :\.

EDIT:

It seems my 6950 is falling into what looks like AMD's 2D GPU limits as I can't get it to go over 725Mhz on the GPU no matter what I do:

As I mentioned, doesn't it purposely limit processing power in 2D applications (the desktop) vs 3D?

I am getting a lot of rpc errors too. Website says they are adding better load balancing and a chicago server.

Last question, what is the difference between unconfirmed, estimated, and confirmed rewards?

How does everyone feel about a 5830 and a 5850 backed by a ~1 year old 550w OCZ Fatality PSU?? Think I'd be okay for 24/7 mining? At least for a few months until I'm back stateside with Newegg access?!

Edit: I've traded my GTX460 for a 5830 straight up and can get an XFX 5850 black ed. for about $270 USD, which is an awesome deal for Brazil!

I am running two 5830's on that exact PSU with no issues. Runs 24/7. The rest of the system is low wattage though (45w cpu, 1 hd, no dvd, etc). If the rest of your system is not eating a lot of juice then it shouldn't be a problem as a 5850 is lower wattage that a 5830.

mining doesnt need a big PSU i've discovered. I have a rig with tri-6950's running at 1v @ stock clocks (down from 1.1v) with the memory at 300 mhz, and my kill a watt meter has it pulling about 500 watts @ 945ish MH.

Hmm it looks like I earned .011 BTC in 3 hours and 45 minutes and then earned .014 BTC in 8 minutes. Are those huge blocks common? I saw another 3 hour block in BTCG's history.

btcg works like that for me, too. A while with barely a return, and then a good amount to even it out. I wouldnt worry.

Is there any good way to run this in Windows? I have a 5870 + 6950 2GB on the same motherboard. If I run in Linux, is it more efficient?

I don't think it's required to keep it open, just set the threshold to something like 5-10 BTC and make sure you connect to the bitclient when you go over the threshold so you receive your payment.

You don't even need to do that. Basically, your wallet balance is all in the block chain. You could setup your wallet once, get a send address, and then copy it to a CD-R or something, delete it from your computer. You could receive BTC from mining at 1.5/day for months, years even, to that address. Whenever you install the BTC client and use your original key you will see your full current balance, just like magic.
