Yeah I think your theory is correct. In one thread there was a guy named milkshake and another named shakezula. It was like an Aqua Teen Hunger Force party.

Get ready for MC Pee Pants.
unless a new altcoin has demonstrated its development in the community somehow (like MC2), it, along with all of the frantic i-dont-have-time-to-use-the-search-feature-i-might-miss-the-premine threads need to be moved to:

First a note on my project - making the molex riser is easy as oatmeal. First time, including watching a video on soldering (it has been quite a while heh forgot to use flux as I don't use it with LEDs), and practicing a few times <20 min. Welds are solid. Will take <5 next time 
But comp still crashes sporadically every ~5 hours. What a pain I'm pissed at my rigs right now - but thats another topic..
Not true! I sell them as well for much cheaper, and based in the US
Thanks for the info Cryptocables, you have decent prices for sure! And domestic shipping is LEGIT.
That Is a trick I surely will have to try...

I think Cablesaurus is the only molex-modded seller. I'd look into how to make my own but with BTC (and LTC

I buy chinese 1x > 1x risers and file off the end so it is open ended. 2 bucks each, and easy to plug in/unplug. Won't damage the video cards or motherboard. I find 16x risers need an excessive amount of force to plug in/unplug and the risers easily break because of this.

Would this be worth mining on a farm of 40 rigs?

subSTRATA - lol finally a laugh
I can't tell if people are trolling as idiots (instead of cleaver trolling, which seems to be dying these days) or are just idiots.
saberu - stop trolling.
I saw those from Cablesaurus ... not sure with the molex connector is for. But this could explain a lot due to differences in power specifications:
"All sizes of ×4 and ×8 PCI Express cards are allowed a maximum power consumption of 25 W. All ×1 cards are initially 10 W; full-height cards may configure themselves as 'high-power' to reach 25 W, while half-height ×1 cards are fixed at 10 W. All sizes of ×16 cards are initially 25 W; like ×1 cards, half-height cards are limited to this number while full-height cards may increase their power after configuration. They can use up to 75 W (3.3 V/3 A + 12 V/5.5 A), though the specification demands that the higher-power configuration be used for graphics cards only, while cards of other purposes are to remain at 25 W.[10][11] Optional connectors add 75 W (6-pin) and/or 150 W (8-pin) power for up to 525 W total (75 W + 3×150 W)" from http://en.wikipedia.org/wiki/PCI_Express#Power
So by plugging a x16 card into a x1 riser, you're only able to pull 10-25W max from the PCI-E side. A graphics card might be expecting 25-75W, hence the instability.

Good Find! That may well be the problem if I'm reading that right. I'm going to mod (https://bitcointalk.org/index.php?topic=76121.0) a spare 16->1x riser to have molex over the next few days (hopefully tomorrow) and will retest the system for stability and report back.
In the mean time... Anyone want to chime in on what manufacturers/vendors you like to use?
In an attempt to vet some stability issues I've been having the last few days, I've come to decide my risers could be a contributor (drivers crash with them, sporadically, and with 7950s directly in mobo: stable for hours and hours +).
What brand risers do you use / trust to put in your rigs?
Are there any you're suspicious of for quality reasons?
Other reasons behind these crashes you can think of?

Hey TacoTime!
Kudos for this!
Can you possibly add the feature of multiple saved profiles? For instance if I want to swap pools or hardware you could go File -> Load Settings -> Profile 1, Profile 2, ... Profile n? Custom profile names would be cool too

It's sounding like a software issue? Have you tried on another platform/OS installation? Also, you might check your bios version and flash it to latest. What is the specific motherboard model and power supply model?
I think it could be two things:
My MSI Z77Z-GD80 has 3/7 slots which only see my cards as 'Standard VGA Adaptors' - I've tested the mobo on 2 PSUs, and multiple GPUs which can hash as a single for 10-20m without crashing. These slots worked previously. Also, I reset the bios, and tried the "B" bios on this motherboard and the exact same thing.
Current plan for tomorrow: check drivers are current to be thorough. Otherwise I'm considering calling MSI...
+
My GPU bios' might be corrupted? I'm thinking this because I wiped my OS on rig#2 (all PCIe slots work, no fishy business with core system) now that I had free time today. After hooking up my GPUs which hashed fine for ~10-12m at stock, I let 2 of them hash away and after ~2 hours one crashed. Reset drivers, and other card crashed after similar amount of time.
For the MSI system - I also reinstalled win7 today (I had a lot of background time) to ensure I had clean 13.1 drivers, and swapped PSUs -> same problem as before with 3/7 slots, and even on the 'good' slots GPUs crash after a while.
The strange thing is that if the GPU bios' are corrupted, it happened to all cards on both systems nearly simultaneously. They both were running through a surge protector but I'm at a loss as the initial cause unless these particular cards (sapphire 7950 vapor-x) are vulnerable when underclocked to bios corruption.
I'm kind of running with the noob assumptions of GPU bios so I could be waaayyy off.
Mobo: MSI Z77A-GD80
PSU: Rosewill LIGHTNING-1300
PSU2: Kingwin 850 (one i just pulled out today)
Thanks again for all your help it's extremely appreciated!
Linux using ssh and screens?
This is my goal, I've yet to learn how to ssh. Any guides/websites/help you'd recommend (I know I'm being lazy, I just don't have much time for another 2 weeks so direction is appreciated in the mean time)??
Dummy plugs. I have no problem at all running headless with one 100 ohm resistor.
Sounds like I'm going to try this:
http://www.overclock.net/t/384733/the-30-second-dummy-plug
in the mean time, as after tomorrow morning I'll have the resistors, which completes all the supplies I need.
dummy plugs are quite an elegant improvised solution considering it'll cost practically nothing (9 resistors).
Hi,
I'm looking for a way to setup my 3 rigs (either to a master computer or via internet) so I can:
1) restart drivers (can be done via windows mouse control)
2) restart comp (must boot on startup and log in)
3) start stop cgminer (same as 1)
4) monitory temp/hashrate (same as 1, but preferably not needing that route)
Anyone have similar needs or have met any of these?
I've used teamviewer a bit but it crashes my 7950 13.1 drivers sometimes upon creating connection (sys: 3x 7950, 8gb ram, >750 PSU).
What do you use?
Teamview doesn't consistently work when system is headless -> black screens upon connection which wont go away unless screen plugged in.

dont think it would damage your motherboard... have you checked the psu rails with a voltmeter?
No I haven't, but I do have a voltmeter. Do you have any recommended guides? If no I'm looking at this one http://forums.extremeoverclocking.com/t137886.html
What rails would you measure (same as guide? 12v 5v 3.3v?) ?
ofcourse you could mine LTC... but also look at FTC...
going for about 335 FTC = 1 BTC at the moment..

That's so interesting. Crazy how far hype/bandwagon can take a cryptocurrency. It has nothing special to offer.
Thanks Sinergy,
What is you hash-speed with those settings (just curiosity)?
I mainly need help determining if my mobo is fried?
If so hypothesis as to how from undervolting it?
And, what test would you run on your cards (how long do they need to hash as stock settings; or some other test) to determine if they're damaged?
Or any other suggestions as to do some hardware testing/troubleshooting.
I was mining stably for a few weeks, and never had overheating, driver crashing problems, etc. Until I undervolted the cards for half a day and both my rigs crashed.

I've never heard of undervolting hurting motherboards. I would reset your bios (unplug from wall, remove battery, switch cmos switch, wait 30, reverse) and try system restore or last-known good on bootup. Should fix the issue.
So, reset bios, reinstalled drivers. Teseted all GPUs to see if they could hash for 10m stock (probably not a long enough test to determine health): 7 passed, 1 causes system to boot to some 'corrupted' / must repair mode; I don't remember specificly but I've never seen it before - sounds dead.
For the motherboard, I get 4 slots that recognize 'passed' cards, and 3 only recognizing them as 'standard VGA adapter'. Ideas?
Also, I took two 'passed' cards at stock, set to mine over night. One crashed at ~2 hours, another at ~3 hours. So frustrating.
In a few hours I'll be able to start QC on my other rig and can cross-compare gpu's on that one
+1 This is where I would start as well, unless the real issue is the SO jamming a fork into it while he is a work...
Good thinking, but 1) I know she was out of town, 2) I trust her.
I'm using cgminer directly on a headless machine running xubuntu 12 with catalyst 13.3 drivers. You can try adding the --gpu-powertune 20 to the cgminer parameters but it seems like GUIMiner is already doing this since you're hitting 635 and if you\re using GUIMiner I'm assuming you have a screen connected - which intensity 20 that might be causing the errors. Try using cgminer directly by unplugging the monitor and sshing into the machine and running it. or maybe just run guiminer and unplug the monitor and see if your pool results change
I unplug the monitor once the system start hashing. I'm in the process of trying to decide on a good headless method I can monitor remotely. Your system sounds reasonable. Do you use anything to monitor remotely?
I'll keep doing my research as I haven't sshed before and am new to networking, but I already run mint on my main system so crossing over to linux wouldn't be too bad.
Just slightly off topic but what settings - if i may ask - are you using for the Sapphire 7950s? The one in my rig is running at an avg of 603 kh/s, getting it to 630 would be nice. Currently I am using cgminer with
shaders = 1792
intensity = 20
engine = 1075
memory = 1500
w = 256
thread-concurrency = 25088
lookup-gap = 2
threads = 1
auto-fan
and nothing else. I experimented for a day or two with all sorts of settings but this was the fastest I could come up with. Have I missed something or is it just my card? The model I am using is
http://www.newegg.com/Product/Product.aspx?Item=N82E16814202026
EDIT
Just found a tip somewhere else on the forums here - enabling powetune +20 effectively turns it off and stops the cards from trying to save power. it increased my hashrate from 603 kh/s to an avg of around 635 kh/s - thanks roy7 for that tip.

Can you share your powertune resource?
I was getting 635khs with:

Thank you for putting this out there! Just a couple of days ago I was scrounging around the net searching for some good videos for my own edification and so I can share a good resource too, no such luck then. But now, they have arrived!
Udemy is a respected MOOC site. They are pretty tightly integrated with facebook and thus drive NoScript nuts. No worries mate

Hello all,
I have 2 rigs, both ran stable with 3 sapphire 7950s at 1.25v ~635khs scrypt mining untill ~2 days ago. I got a complaint from a significant other about the 'intense heat' blah blah; I retorted that my cards were only at 65C and not to worry. That only made the situation worse, go figure. So in an attempt to appease I decided to try to undervolt my cards to increase their thermal efficiency. I got tested out one card and got it to hash stable at 1.09v with minor khs loss (final ~620khs). So having to go to work I undervolted the rest of my cards with Trixx and waited for 30 min. All seemed good so I left; while at work both systems crashed within a few hours of ea/ other.
On sys one (my MSI mobo system), I ran some tests: reinstalled drivers, clean OS wipe -> neither fixed it.
Reinstalled drivers again, and tested slots individually with one tested working GPU. 3/7 slots wont let me boot using GPU as video source.
Well at least I have 3+ pcie slots on my machine with 3 GPUs... WRONG. It turns out 2 cards will hash at stock settings, but a third (even at stock settings) causes my driver to crash, regardless of the slot combo.
It looks like its the mobo?
How can undervolting damage a mobo?
I never had any temp problems (always around 65C) or stability issues before this epic crash. I haven't even had time to check out the other comp except I know it wont run it's three cards after a driver reinstall either - haven't played with slots.
ANY other ideas I can try? Super bummed I might have killed a mobo by undervolting (I know there is risk, but I believed undervolting couldnt do that)!
Much thanks in advance. Even drunken ramblings (roughly on topic) are appreciated!
