Thanks for the reply, the PSU is a corsair http://www.newegg.com/Product/Product.aspx?Item=N82E16817139007When I have 3 x 6970 in the rig, the system will start for 1/2 a second and then dies, nothing would power on (though mobo still show the small power indicator light). If I put 2 x 6970, then system would boot up fine. A 1000w psu should be more than sufficient but we need to know what psu you are using. I do not recommend undervolting any cpu below its specs. Regardless if it seems stable, long term damage still applies. Also please be more specific on what you mean by "rig won't start". Do the fans power up on the cards? Does anything power up at all? We need more info.
Try lowering the "Boot" clock speeds (cut them in half) using Radeon Bios Editor and re-flash each video card. Should use about half the power on boot up. |

What's wrong with GigabyteCoin??? |

Thanks guys.
So in general they will replace it no matter what, up to a maximum or 2 replacements?

i am little afraid, shall i sell now before the price falls below 20 or even 10?

Is it "acceptable" to most reputable PSU companies to run a PSU at 50% load 24/7? 75% load 24/7? 100% load 24/7?
I doubt they would honor their 5 year warranty if you kept blowing through PSUs every year or two, no?

Would have better hopes in the marketplace section with this thread... Just be active in the forum and post a link in your sig...

Who'd a thunk this would have caused such a stir???  Went and bought a few OCZ 1250W Golds... thanks for the advice gentlemen! |

Not to be a jerk, but that sounds like a really good way to kill yourself. Playing with 10+ amps is not a good idea.
Yes PSUs are transformers, but they're also filters and some other stuff.
No offense taken! I don't know much about electricity yet... but it sounds like a pretty simply job. |

Nope, sorry, you missed the money train.
J/K - it is still insanely profitable to mine.
In fact - apparantly difficulty cannot jump more than 4X in one "round"... BTC has been jumping almost 4X per "round" recently... so if that continues or increases mining should be profitable for a while yet.

Just almost set my entire mining rig room on fire... With shitty PSUs apparantly. I hooked up 2*850W raidmax gold PSUs to 6 video cards and it started smoking like crazy. I can hook up 6 * video cards to a 1200 watt gold psu with no problems whatsoever. WTF raidmax?!? You made me inhale some kind of weird assed fumes!

I don't get it.
You're complaining at yourself for not knowing the future?
Bitcoin might aswell have had its peak at $5 and maybe it would've never risen above that. You could potentially have lost thousands of $'s.
Mining dying? No, mining can't really die, it can just get harder. Someone HAS to find the BTC's before they can be traded.
I like your thinking. I too could have spent $10k on bitcoins - which could have been worthless tomorrow - instead I spent it on mining equipment - which I can sell tomorrow for at least 75% of what I paid (since I bought it all used in the first place). Had I have spent $10k on bitcoins - I would be nuts... now I am safe and semi rich. |

I am considering spending almost $1,000 on 3-4 gold rated PSUs.
Seems to me they are little more than transformers.
If I could purchase 4*$30 PSUs simply to run the motherboard/cpu power... could I note create a massive single 12 volt rail that distributes power to say 30-40 video cards via pcie connectors at once?
I guess it would really suck if THAT power supply broke down... but still - anybody tried it or similar?

Well like I said... thankfully everything still works. I can boot up the computer fine. Both of the power supplies turn on fine.
I only have a 20W CPU running, a flash drive for hdd, and 2 gb of ddr3 ram. That is my "system". So really each PSU is pulling 670 watts at most. For an 850watt rated Gold PSU I would expect that to be kosher.
Raidmax is a slightly lesser known name however... could be them?

So I just setup my first dual PSU rig...
Two raidmax gold 850W PSUs (one with a shorted green + black ATX power cable to keep it powered on) powering 3 * XFX 5870s and 3 * GIGABYTE 5870s (OC Editions)...
All cards are connected by extension cables except for one which didn't want to work in an extension cable for some reason so it's plugged into the mobo.
I start up the computer, all is well...
I start the first few miners, all is going smoothly.
I begin to check the temperatures about half way through setting up the miners in a terminal, and notice that one or two of the cards is already at 90 degrees celcius. Which is odd... they are 5870s with 950core/300memory clock settings hard coded to the BIOS with almost nothing else changed.
Some of the cards (presumably the gigabyte's) are running just below 80 celcius like they should be... but 3 of the cards are just burning right up to 92-93 and sitting there.
I have my fans on continuous all the way from 0 to 100, so they should have been running at about 92% at that point in time.
Something starts to stink. Not sure what it is... assume it's just cheap glue burning off the pcie extension cables and/or that "fresh plastic smell" coming from the brand new cards perhaps.
I stupidly leave the room for a few minutes... only to come back and find that the room is now filled with a light grey smoke.
The computer is still working thankfully, and all cards are still mining... but I obviously shut it off ASAP and that is where I am at now.
The weird thing is... everything looks ok. The cables, the cards, the mobo... I can't tell exactly where the burning smell/smoke is coming from - I can only assume that perhaps xfx of gigabyte can't take the 950/300 clocks and they are literally burning up?
The PSUs were only running at about 85% max.
Another possibility is the fact that I have pcie power cable splitters? But this is not a problem on any of my other two rigs...
Anybody have an idea? Should I be "un-shorting" the green+black wires on the second PSU as soon as I short them to turn it on or something? Very worried about turning this baby back on...

Why not sell this for BTC?
Because I need the cash ASAP to buy another motherboard and PSU!!! BTC -> LR -> CASH is just too long considering the difficulty is skyrocketing. |

Is there any significant performance difference between running Phoenix on Windows or Linux? I'm building a dedicated mining rig and I'd like to know if there's a particular advantage to one or the other operating system.
No, there shouldn't be. |
|
|
|
|
Allllllllllright never mind!?
After about 5-10 minutes all miners are now back up and running without any action on my part.
How did this happen? What is the reconnect rate set to by default on phoenix miner?
