I'm having problems connecting too. 5 out of 6 miners are having problems trying to connect. It would connect for a couple minutes. And then the miner would restart itself when it had problems.

I have a similar setup as you:

Hardware:
Asus P8P67 WS Revolution
Intel Pentium G620
Corsair AX1200 PSU
4x XFX 6870 (2x ZDFC and 2x ZDBC) -- no crossfire bridge
4z DVI homemade dummy plugs

Software/OS:
GUIMiner-20110614
AMD CCC 11.6 Drivers
Windows 7 Pro 32-Bit
GPU-Z v0.5.3

Are you using the latest AMD drivers, GUIMiner, and GPU-Z?

In the beginning I had problems where all 4x 6870's weren't able to run at 100%. When I ran it 4 at the same time, the hash rate would fluctuated between 50-150Mhash/s on all fours. Normally a 6870 OC'ed, I would get somewhere around 270-275Mhash/s (960/1175/1175v). Did some careful research and found out the problem and it was due to temperature being too high (90 degrees) which lowered the performance. Since you have those extenders, it shouldn't actually be a problem for you (maybe). I had to buy an extra fan and had it actually sit on top of the graphics card to lower it down to somewhere around 70-80 degrees. Temps for the graphics card shouldn't going higher than 85-87 degrees, IMO. If so, it's not good for the card.

As for the dummy plugs, I'm actually using this:

You can buy the DVI-to-VGA adapters for less than $2 from Monoprice.com. Resistors got them from Fry's for 99cents for a pack of 6 resistors.

Hopefully, this helps solve your problem

the manual seems to indicate all 4 PCI slots should operate at 8x.  it could be that the 32-bit OS can't handle all that bandwidth.  you may want to try asking ASUS as well....  good luck.

Hmmm... interesting. I'll probably check out the OS first and see if it's because of that. I might actually just try installing Ubuntu on it instead and test if the problem still exists.

Looks like it's the OS + software that's causing the issue according to this thread http://forum.bitcoin.org/index.php?topic=19038.0

I guess I really have to use Ubuntu to get all 4 going.

I have said it before and I will say it again. Plug your ears.

GET AND USE A RELIABLE PASSWORD MANAGER!!!

I suggest LastPass, it is easy to use.
You can have it automatically input your user ID and password to a site as soon as you get to the page.

Still to hard? You can get it to log in for you.

Want to know the first part of the password that I use for this forum?  It is A&Vyg followed by at least 5 more letters.  I had to look it up through LastPass.

I can not tell you the passwords of any site that I use, because I don't know them (LastPass does). I can tell you that it is a strong password.

I can also tell you that birds are going to fly, fish are going to swim and hackers are going to hack.

Can I get an Amen.

Amen.

AMEN!!

I understand all too well that if people are allowed to choose ANY password at all, they will usually choose a weak one. The onus of security is not typically placed on the user, it is up to the institution to FORCE the user to choose a minimum acceptable level of security. This is why every major OS has systems built in to enforce password length, complexity and expiration requirements. Users cannot always be counted on to choose methods and systems which are in their best interests.

It's yet another extension of that classic rule of programming: "Always assume your user is an idiot (even if your only user is yourself)"

True that.

But then on the other hand programmers should implement rules where password should at least consist 2 lower case letters, 2 upper case letters, 2 numbers, 2 symbols, and a minimum of 8 characters as a requirement for password. But then again people would just make their passwords simple like qqWW11@@ or maybe even qwER12#$.

Hi,

I'm currently having problems trying to get a computer up with 4x 6870's mining rig going. This is what I have:

Specs:
Asus P8P67 WS Revolution
4x XFX 6870's (16x, 8x, 8x, 8x)
Corsair AX1200 PSU

Drivers/Software/OS:
AMD lastest drivers
ATI APP SDK 2.4
GUIMiner-20110614
Win7 SP1 32-Bit Pro.

I was able to get 3x 6870 to start mining which each of them going at 255+Mhash/s (some higher due to OC'ing. However, once I started the 4th one, all the other GPU's started to drop down between 50-150Mash/s. It would keep on doing that and all GPU's would not max out at 255+Mhash/s.

Anybody have any ideas why this is happening?

I wasn't able to find anything on the forums (based on my searching skills) regarding motherboard only having a max number of GPU's. For what I know, you can have as many GPU's you want on the motherboard no matter how fast the PCI-E lane is whether its 16x 8x 4x or 1x. Correct me if I'm wrong.

People are just plain dumb, cheap, and lazy. Use a password generator that can generate a password using letters, numbers, and symbol. Then use those password managers (1password or whatever) and that's it. It's that simple.

And when the people who use simple password gets hacked, they blame on the site that got hacked. People need to understand that there's nothing in this world that can't be hacked. It only takes time for one to be able to hack something. A site can only take precautions and implement firewalls to prevent one from hacking.

It's just super annoying that one would just blame someone that their user account got stolen because of their stupid password like 123456.

Hi,

Name is nikkuchan. Been mining for a couple weeks now. Still learning all these amazing knowledge people have in here. Hope to talk with people and guide me in the right direction. Nice to meet with everyone!

Hi,

I would like to request to submit posts in other sections. Reason is because I was trying to get hold of Slush to notify him of errors I was getting a couple days ago in Slush's main thread when the DDoS attack was happening, however, couldn't due to restriction. In addition, I would love to contribute the knowledge I have from reading all the posts in here to other miners. Thanks in advance!
