i run 2 5830's on 600W psu
oc'd to 876/292
600W is barely enough IMO for this setup
I had to pull out 2 sticks of ram out of 4
and disconnect 3 extra fans, currently running 2 fans besides cpu and gpu fans, open case
You should be well under 600w, unless your PSU is really over-spec'd. 4x - Radeon 5830 reports 650 watts max on my Killawatt meter. But i do have rig built especially for low power. Are any of you over-volting your 5830? If so, how much? |

Same problem here: Server is Win7 x64 SP1 and client is Win7 x32 with no updates. I'm going to try XP next on client. I noticed some weird behaviour also. Locally I was able to get GUIminer working, but then I tried to repeat my results, I can no longer connect to local bitcoin server.' GUIminer client on remote client PC is stuck in "connecting" mode. Here is my TCP/IP scan:  Seems to show local GUIminer is connected at 8332, but GUIminer doesn't think so. |

Bump.  |

Bump. Someone must know how to fix this.  |

Local PC is mining as RPC client, but i can't get phoenix to work at all. GUminer is not able to connect from 2nd PC.
https://en.bitcoin.it/wiki/Running_Bitcoinyou probably need to add "rpcallowip" into config file... When I add that command to command line or conf file, this happens:  |

What is the format for command line mining (solo) while connected to LAN bitcoin server?
I am using win7 on both PC's. Local PC is mining as RPC client, but i can't get phoenix to work at all. GUminer is not able to connect from 2nd PC.
Help!

I am unable to get win7 x32 GUIMiner on PC1 to connect to win7 x32 bitcoin client running in server mode on LAN (PC2).
GUIminer is running solo, with host set to x.x.x.x user/pass is entered correctly.
There are no errors except for connection problems issue. PC2 Bitcoin server can mine coins just fine, same with GUIminer running locally.
Firewall is off, MSSE is off. What could be the problem? What should I check?

No! Not a usb stick!
What we need is an MP3-player-ish Bitcoin dispenser Fallout style. ;^)
It should have a LCD display to show balance/transfer status etc, and two dispensers should have syncing ability (wired or wireless).
Another requirement would be dual flash chips and/or memory cardslot for redundancy.
Obviously this would take some development by a company with deep pockets.

Trick to getting around Trixx/Smartdoctor not seeing second card -- start off in CFX, overvolt the cards, then switch CFX off. Assuming you have dummy plugs in, the overvolt should still hold on both cards. From there, use MSI AB to clock them up to where you want.
(dunno for sure if that works on Trixx. Maybe if you go CFX, overvolt, close program but keep settings, then switch CFX and OC using MSI AB)
That is a good trick. However, I have three cards, and so can't CFX all three cards (5850 only has one bridge on top). I suppose the workaround is to test each card for best settings, then flash the bios with the desired volts/clocks. |

Very interesting project. Waiting for somebody clever enough to work this all out and tell us how it is done exactly.
Most laptops take about 90W-120W for the whole system.
Say the card takes 200W + 120W = 320W for a system mining with one 5870 or 6950 etc.
I'd like to see you doing that with a normal desktop !
Easy. Athlon II 160U socket AM3 processor draws 20 watts at load. I have seen systems that draw 75 watts total (minus PCI-e cards) that were NOT using the 160U. |

Please show guide for solo mining also! Thanks!  |

Sure, the PSU can do it. But if your PSU fails it might take some components with it. If the line conditioner fails, the PSU should still be able to protect the PC from getting fried.

Its much, much cheaper than frying a board full of 5850's, which could cost you all your parts AND weeks worth of lost mining.
Not everyone has stable power. Those who do tend to not see the value in line conditioning. Its insurance. Not an investment.

I think bitcoin mining is going to quickly separate the men from the boys when it comes to PSU brands. We are going to see a lot of blown up power supplies!  Thermaltake wasn't banking (pun intended) on bitcoin taking off. |

If the internet goes down anyway, what is the point of keeping the system on battery backup?
Just have a reboot cycle when the power comes back on.
For voltage regulation, the Tripp Lite LC1200 can provide sag and surge protection for up to 1200 watts. It also has $25,000 connected equipment insurance. I've done some research, and it seems this LC1200 regulates power better than some UPS units. Given that 1000+ watt UPS units are very expensive, it is likely that many people will buy the cheapest one they can find, and unwittingly achieve worse line conditioning than the LC1200.
I will get two, I think. For $120 each, seems to be the most bang for the buck.
There's also an 1800 watt unit, the LC1800 but its nearly 200$.

I can't get this card to run consistently. I have generated 0.005 coins in a a few days with deepbit, but its constantly telling me hardware verification has failed with latest GUIminer. ATI Stream 2.1. Win7 x64. It doesn't matter if i use stock speeds, overclocked, underclocked, underclocked memory, vectors/no vectors, -w option etc. Am getting 60-70 mhash/s. Fanspeed=locked at 100%. Temp: 71c. My system passes prime95 with EC for 12 hours.  |
