Some updated pics. ... Thoughts, comments, suggestions?
She's a beauty, DAT. Well done - and without a single blue led or cold cathode. Looking at the average watercooled rig I wouldn't deem omitting some sort of l337 light source possible

Yeah, that parameter list looks good - as long as you want to set 1+210V at the core. I doubt any card will comply, though. You should really give --gpu-vddc 1.025 a try.
BTW, why do you mess with command line arguments instead of gathering them in a single config file, anyway?
DiabloMiner doesn't have any voltage control routines coded in so you're going to have to fall back on another utility, like MSI Afterburner or Trixx.

Maybe not on the way out of the US, but the only way to get round import duties when coming *in* to the UK is by a fraudulent declaration on your part, which I wouldn't dream of asking you to do.
For European sales you're going to need a reseller - individuals / small companies here buying directly from you will end up paying hefty taxes (there's import duty, then 20% VAT on top of that) which reduces your competitiveness.
Right you are, Catfish. I got stung when I bought my Zosma Phenom II 970T (Zosma is a codename for Thuban-based quad core Phenom AMD decided to sell OEM-only). Not because I asked the seller to misdeclare the package, mind you, but rather because all the documents were in Chinese ^^ The customs office held the poor sodding CPU hostage for a week and I needed to prove how much I'd paid for it so that tax and import duties could be calculated.

Just exactly which model did you have, the LIGHTNING-1000 or RBR1000-M? Perhaps the white arc you saw was just a lightning bolt and everything is in order? The RBR1000-M is a multi-rail design, you might have botched the load topology - then again, if the protective circuitry worked as advertised the PSU should have shut itself down to prevent a failure. 1005W at the wall translates to ±820W on the DC side of the PSU so you should have been reasonably safe. You definitely didn't overload the PSU unless the CPU got highly loaded when you were gone and required much more power. Frankly speaking, Windows is perfectly capable of doing that. You may have gotten a flawed PSU this time, do remember that the 750W model worked fine even though it was slightly overloaded (with 950W on the AC side, the estimated DC load is again 800-ish). Truth be told, you're pushing those 5970s very hard. When you overvolt a card, the power consumption rises proportionally to delta voltage squared. I don't think I've seen any 5970 draw more than 280W... ask DAT, he has a small farm of 5970 cards. Make sure you enabled all CPU power savings options in the BIOS (AMD cool'n'quiet and C1E) and that you don't use a flawed driver version resulting in totally unnecessary high CPU load when mining. Vmarchuk is correct, you don't usually want to push the PSU further than 80..90% of its rated maximum continuous load but keep in mind that the actual PSU load should be measured on the DC side. When the best you can do is measure at the wall you need to multiply the readout by the efficiency factor∈(0, 1] which should be at least 0.82 for a bronze-certified PSU. Pay no heed to that online power calculator, mining is a totally different animal than gaming or any other typical PC use pattern. Trust only your kill-a-watt. When in doubt choose Seasonic PSUs - their 7 year warranty period is a fine testament to high quality design and manufacturing. A manufacturer can't cut corners and expect their product to work flawlessly for seven years.

I tried your method jake and I can call miner-launcher manually and it starts cgminer however despite having the above line in etc/rc.local "nothing" happens on boot. Any ideas?
I'll get to debugging it when I'm done with my work for today, it's gotta be some minor quirk as the code looks fine. For the record, I came up with this three-file approach when JWU42 asked for advice. I launch my miners in an even more convoluted way

Any progress pinpointing the source of those stales? Mint is hitting 1% stale rate at 103 GHash/s - it doesn't look like GPUMAX is to blame...
EDIT:: I've been getting slow LPs lately - maybe that's some sort of a clue.

Yeah, good that you mention that: RealSolid even stooped to stealing FREE CODE. Seems that giving credit where credit was due was too much. SC devs wanted to use the Bitcoin codebase but not give any credit to the hated Bitcoin itself I found this marvellous piece of FUD and propaganda ludicrous. RealSolid be a-waiting; a-waiting with his fingers crossed for the fall of Bitcoin... He might as well be waiting for Godot for the fallout from Bitcoin's demise would destroy trust in all contemporary crypto-currency systems. His precious 12M premined coins would go for a dime in the ensuing firesale. Just food for thought in case anyone actually wondered whether or not they should take SC seriously.

I'll be taking an extended break from coding on cgminer shortly since most things are stable at the moment for my sanity.
This begins now and I have disabled all notifications from the forum and github so do not be surprised when I don't respond for many days. Email me if it's urgent but try to use the forums please as there are heaps of helpful people here. Thanks everyone for your understanding. Roger that. You do deserve to get some real life, have a great time.

Don't bother with Bitcoin CPU mining. That 12 MHash/s will take like 5 months to earn you a single bitcoin.
I said dont say that iknow , but would it be worth it to mine lite coin and then convert?
What was unclear about my post? You asked: A or B? I answered: not A.

So I thought I might have logged into mt gox through tor and i read they will deactivate your account if you do so. So when i got an email today saying my account was under review, my emotions took over and i immediately signed in somewhat expecting this. not a second later i looked up and saw i was logging into a different site, so i got in as quick as i could and changed my pw.... but too late.
Did you not check the url? It's better never to click on links in emails but if you need to use one, make sure you and up at the expected webpage.
Sorry for your loss. ...and would you please remove the link to the phishing server from your message? You can't know whether the fake site only collects data or also tries to infect the visiting machines and somenoob might be curious enough to actually follow your link there. If that link was automatically discovered and formatted, do something to fool the algorithm, e.g. change replace dots with [dot]. The http:// part isn't necessary either.

BTW, I've tried to change voltage with Trixx, but GPU-Z did not see the change. Was accepted by the driver but refused by bios, I guess.
Precisely. The driver doesn't check whether or not the card actually honored the change requests and assumes that it did. Programs that query the driver might get an incorrect answer. The only way to check the GPU status is to query the device, not the driver. Instead of - Hey, driver, what clocks is that hd6970 running at? - Ummm... I told it to run at 950/300 so it's running at 950/300. (the card refused to downclock the memory) *facepalm*
use - hd6970, what clocks are you running at? - 950/1370. The driver wanted 950/300 but I told it to shove off.

I've learnt that even if you start a brand new Facebook account, from the ads on the right hand side of my new account, I see that they know I graduated in 1978 and even suggest my sister as a friend as well as an uncle I haven't spoken to in a couple decades. Somebody tell me how the hell is that even possible.
The history of your IP address, the cookie files, flash "super-cookies", cookie-less profiling of your machine (e.g. by user agent, list of browser add-ons, version of flash, version of java, system fonts, screen resolution,...) - the list of possible ways any website can track a user is very long and depressing.

...not to mention the fact that RealSolid did unilaterally shut down the SolidCoin network for a few weeks last autumn. It's unthinkable that one person should have such power over a crypto-currency system. SolidCoin is neither free(1), nor decentralized, nor does it have any market foothold (care to guess why?). In other words, it's a dud.
Notes: (1) as in free speech; libre

Awesome, lads. It's working
It wouldn't dare not to... How happy are you with your 990fxa-ud3? I've been using this board in one machine (not a mining rig) and needed to flash the bios with the latest beta version to get rid of some minor quirks and glitches. The PCIe slot layout isn't perfect for a mining rig as you can't use three double-slot cards and keep one unoccupied slot between each of them.

ckolivas,
I'm running one 7970card with
--auto-gpu --auto-fan --gpu-engine 450-1179 --gpu-memdiff -150 --gpu-powertune 20 -q -I 12 -k diakgcn -d 0 -v 2 -w 256
right now, I see Q: counter steadily increasing, is that something to worry about?
Also, what is the efficiency (E:) that you get in your Linux setup?
On win7, with Sapphire card I'm getting AT avg of 680-685Mh/s, efficiency swings between 75-85%. Is that normal?
Also, I've noticed that sometimes one thread hash rate drops significantly and then the whole thing recovers to above 650 (for two). Is that just sampling of context switching artifact? Or my intensity is too high?
On Win7, I cannot run this card to 1200Mhz the way you run it on Linux.
Does anybody get better AT avg on Windows?
It's all explained in the README file: Q: The number of requested (Queued) work items from the poolsThe sum of all work items cgminer requested from the pools has little choice but to go up. E: The Efficiency defined as number of shares returned / work itemIn other words, efficiency is the ratio of accepted shares to all requested work items (E=A/Q) Efficiency >=75% is nothing unusual, it means cgminer is able to process 3/ 4 of all the work items it requests. The 10 second average hash rate (marked as 10s in cgminer main window) will oscillate quite a bit, you should only pay heed to the total average ( avg). Is that the latest version of cgminer you're running? 2.2.7 had a minor glitch where the hash rate would fall on LP requests. This issue is fixed in version 2.3.1.

Great idea putting your sensitive cards on electrostatically-charged floor
|
|

Id be willing to bet 1 coin you can SSH in to the machine fine even with 2 cards. When you do, try running sudo aticonfig --initial -f then reboot. If that doesnt fix it, try booting with nomodeset. I wrote a howto on this a long time ago, but most if it is still accurate today: http://ubuntuforums.org/showthread.php?t=1613132P4, let's be more blunt and say Hey dummy, use all the cards you got there!: sudo aticonfig --initial --force --adapter=all Nice howto.

great excuse to upgrade my 5750 to a 6970 ^.^ should be here tuesday.
Upgrade? Surely you mean support? Use both cards for mining, a highly overclocked 5750 will net you up to 200MHash/s. That's 40-something per cent of what you might squeeze out of that 6970, surely nothing to scoff at. Do keep in mind that even those two cards working together might barely make up for the electricity the rig using. A single card really won't be able to do much - even amortize the power usage of the mining rig let alone earn you some money. As I already told you a PSU upgrade does seem warranted. Aim for a 650W unit for those two cards (or 750W to allow future GPU upgrades) - these PSU sizes are still relatively cheap. 0% fee only pools: (do note that Slush is not free - they do take a percentage of your rewards) P2pool being pretty well represented here (a bit overrepresented actually), why don't you give Eclipse a try? It's an excellent hop-proof DGM payout scheme pool. Please note that Double Geometric Method means that your revenue is offset in time: you will earn slightly less than expected on your first day but when you stop mining, you will still earn bitcoins for a few rounds. As DAT said, BitMinter is a great choice as well - as long as you don't mind the variation. This pool offers a proprietary, very easy, Java-based miner you can launch with a single click at the website. Eligius is a SMPPS pool totally unaffected by either pool hoppers or block length variation.

... its a 500w peak PSU.
Do not use the PEAK VALUE, ever. The peak rating is meant to account for transient PSU loads, like when the PC boots up and needs to initialize all the components. From the end-user perspective, it is useless. That's a 450W PSU you got there, and not a very good one. Using lousy^Wlow-cost and undersized components (main capacitors rated at just 85°C, bleh) this model suffers from excessive ripple on high loads. I strongly suggest you upgrade your PSU to something decent and sell the old one on ebay to recover costs.
