I have two used HX1050 power supplies for sale, with the original packaging and all original cables/accessories. Pictured here is what I was using, the rest of the original modular cables are still in the boxes. Not pictured is the heavy gauge 110v power cables, which are included.  I'm looking for bitcoin only, please. Would like to get $90-100 shipped per supply (USA) but can work a package deal esp. if you let me ditch the OEM packaging for shipping. These supplies were used for approx. 3 months of mining. Still in perfect shape and working condition. These two power supplies ran 6 R9 290's at modest settings, combined of course. Please PM me with any offers. Thanks!

I need someone to give me a hand with a circuit board design. If you don't like reading and are good at eagle, pad2pad, etc.. PM me.
I started planning a small crypto business a few weeks back, selling litecoin mining cases. My design was to be a little different, so I used the USB 3.0 riser cables I found on the internet. I made the mistake of not checking my suppliers enough, and now I've discovered there's only one manufacturer and he is a real slimeball. He agreed several times to sell me riser cards at a bulk price, but continues to not ship my order yet he still has more for sale on e-bay - at triple the price. I am all but certain my money is stolen now.
So this won't stand, I refuse to do business with slimy characters like this. I have lots of my own money invested in my little plan and I won't see it stolen from me! I need USB riser cables to finish out the inventory of my new case design I already cut, no other riser cables are long enough, but I can't buy them so I guess I will have to make them. I've found all of the components, but I suck at PCB cad work (which is kind of funny!) so I am here asking for help.
I propose I take a bunch of really high quality DSLR shots of the USB 3.0 riser cables I already have to help you lay out a new identical circuit board for me. I will handle everything from that point out, unless you would like more involvement. I am offering .5 BTC for this job, and I have no problem sending the .5 BTC to a trusted forum escrow.
Please PM me with any other questions!
Thanks!

I need to sell 2.75 BTC, and would prefer to do so in person somewhere near the Kansas City area. Please PM me for my cell phone number.
But I am also willing to sell online, but not with paypal. Escrow available, or preferred, open to any non scammy suggestions. No rush, can wait for money orders or bank transfers. Currently only have a small town bank, can open another account (BOA USBank,) probably should anyway.
I am looking for bitstamp last +2% at the most. Willing to go under rate for all 2.75.
Thanks for looking!

Just putting this out there. No idea what the best way to work this would be, but preferably I borrow your GPUs and pay a percentage based on %'s "invested." At some point I buy GPUs, you buy rigs and we go our separate ways. I have 11 MSI z77-g45 boards, cheap celeron ivy bridge CPUs, RAM, SSDs, PSUs etc. "Proof" available on request. I planned on starting a litecoin farm long before the recent spike in price. I put in the research and effort, bought and returned several different types of cards/psus and more. I have a plan for mounting these things up, too. The market had other plans, now I'm pissed I didn't start a week or two earlier.   I am located in the midwest, like dead center of the country midwest. Willing to travel or do whatever it takes to make everyone involved feel safe, you should be willing to do the same. Scam accusations will be laughed at and disregarded. Thanks for looking

Litecoin has given my life meaning again, so I have lots of these codes to sell once again. More to be coming soon...  Make me an offer on what you would like. Bitcoin/litecoin only, please!

What would the best way to do so be? I may be in the market for 60+ 7950's or 280 non x cards. I'd buy the inventory out of most stores, not to mention the rebate limitations. Not looking for opinions on practicality of such a thing or what I might make/loose, just looking for cards Thanks for looking!

I want to try and sell my car for BTC, I've had this car for a while (and used it for my username for about as long  ) I have a 2007 Pontiac G5 for sale. Needs some work, left front strut wheel bearing and wheel. Needs some body work done on the right rocker and rear bumper needs paint. The replacement parts cost around $280. Paint and body work has been quoted $700. Wheel http://www.wheelsandcaps.com/p-21101-aluminum-wheel-rim-17x7-6581.aspxStrut http://www.partsgeek.com/gbproducts/MC/19092-07028314.html?utm_source=google&utm_medium=ff&utm_content=MC&utm_campaign=PartsGeek+Google+Base&utm_term=2007-2009+Pontiac+G5+Struts+Monroe+Front+07-09+Pontiac+Strut+Assembly+2008+08&gclid=CNfEm-fhlrkCFSdp7AodIlkAFQWheel Bearing http://www.1aauto.com/1A/front-wheel-bearings-and-hubs/Pontiac/G5/1ASHF00135/589583/2010?utm_campaign=gb_api_br&year=2010&utm_content=SHF&gclid=CJO2pvjhlrkCFURp7AodwBoAyQKBB for this car in poor condition is $6338. In good shape is ~$7600. Dealers sell these at 11K+ due to the great gas mileage. "This car has some mechanical or cosmetic defects and needs servicing, but is still in safe running condition and has a clean title history. The paint, body and/or interior may need professional servicing. The tires may need replacing and there may be some repairable rust damage." Not a spec of rust, the engine and trans shift just fine and the clutch has plenty of life left. This car is drivable as is right now, but the alignment is messed up and it has a slight vibration at 55 MPH that quickly goes away at 65. A tire/bearing hum can be heard at almost any speed. Has... Cruise, power windows, power locks, Factory pioneer 7 speaker stereo W/sub, XM/Sirrius radio with aux in and plays MP3 CDs. Replaced steering wheel with a leather wrapped Cobalt SS one, has radio and cruise controls on wheel. Still have the original if you want it. Wheels are off a G5 GT, 17" alloys W/ low pro tires. Windows are tinted 15% all around since new, no faded interior. Rear tires need replaced, fronts are relatively new. I recently replaced the front rotors and pads due to warped pulsing rotors. Two rims were jacked up by some punk at Firestone in Olathe. Not rash, but paint has chipped. One center cap is missing, common for these wheels unfortunately. The entire body kit off of a Cobalt SS was fitted onto this G5, that is front and rear bumpers with rear lip, side skirts, and tall spoiler. All OEM parts. The right side skirt will hide most all of the body work that needs done to the rocker. I still have that piece. Oh, and a cracked windshield. I will not sell this car for much less ($4000 or BTC equivalent) and I don't really need to/have to so don't bother with ridiculous offers. I still drive it to work when I don't feel like taking the truck/motorcycle. If I can't get what I'm asking I'll just fix it myself. The only reason I'm not fixing this myself is because I don't have much free time, and I'm tired of it being parked in front of my house. I'm trying to not waste your time, so please return the favor. Thanks for looking! Edit: Clean title - No damage or accident ever reported anywhere. Carfax isn't as thorough as they'd like you to believe! Also, sorry for the dirty pictures

I bought a new set of graphics cards for my computer, mainly for gaming but I intend to run them when not at home for extra heat during the winter.
Anyway, I have two sapphire 280x cards. I managed to get them hashing at 750khash pretty easy (2048shaders, 8192TC 256ws 2 thread g2 lg2 i13 1080/1500 - ~75C)
CGminer reports around 1.495mh/s, but a WU of 1364/m. From some searching I found that it is somewhat dependent on variance, but should settle to around 9/10 of total hashrate. Does this sound right? The pool reports 1.3 to 1.5Kh/s most times.
I also have a 7870 running in another rig (1280shaders, 15232tc, 256ws, g1, lg2, 1 thread, i18, 1000/1500 - ~80c)
This pulls 420Kh/s, but my WU is showing as 450/m after running several hours. It's a crazy intensity, but I get no HW errors and my pool recognizes ~420k/s.
Am I mining good and just seeing variance or something? I seem to be getting paid based on my hashrate, so I'm a bit confused on this WU thing...

I am trying to control a lot of fans, I am not at all interested in potentiometer fan controllers, PWM controllers, set voltage regulators, or anything other than what I am about to describe. Sorry for the long winded mini-rant... Lots and lots of fans, but not anywhere near enough current provided by fan headers. These are only 3 pin fans, no PWM. I want to use the analog voltage of my built in fan controller to drive a linear regulator reference, giving me a lot more total wattage of fan control. I believe the best way to get this done is a simple linear voltage regulator, preferably a low dropout kind. I will only be using 12V from the ATX supply. I have a few low dropout regulators I believe I can make work, but I'd rather have someone more experienced check my work for a fee. From some light research I think I can do it with a pair of diodes and some input/output filter capacitors. The regulators are BA00CC0WCP-V5E2CT-ND, I'd prefer to use these since I already have them. The data sheet can be found here... http://rohmfs.rohm.com/en/products/databook/datasheet/ic/power/linear_regulator/ba00dd0w-e.pdfIf this is something you are interested in please let me know via PM. Please also let me know what you think fair compensation would be for this work as well. Thanks for looking!

I want to play some JD, but I don't want to spend the bitcoins I am "saving."
I have ~27.5 LTC for collateral, plus a history across a bunch of web forums if you know how to search. I would like to establish some history here as well.
I'm going to gamble with your loan and repay with BTC if I do loose it all. I can repay you, I have ~15Gh plugging away at BTCguild for a while now. I make ~0.05 BTC a day, so at the worst ~2 weeks to repay. If it isn't obvious that I really don't need this loan I don't know how to make it much clearer than this.
PM me and let me know what you'd like for terms. Thanks!

I am upgrading my mining rig to watercooling, switching it all over to a new case I made. I would like to sell the old case for BTC.  Note: I couldn't get that to cool, better fans or more experimentation may help. Please read the following thread if you are seriously interested! Here's the original thread, when I first built the rig. There are a lot better pictures in this thread! I've had this thing mining pretty much every day till yesterday since I posted that thread. Solid, practically indestructible case. Made from 14ga 304 SS, this stuff is tough and will never rust! All mounting points are threaded insert rivets. All hardware/allthread for the riser cable bracket is also stainless. https://bitcointalk.org/index.php?topic=190062.0This base was designed to run 4 cards on the motherboard, but I am also including a bracket that lets you run as many cards as you can fit with riser cables. It will need some tweaking or bending to fit your specific card length. You will also need to drill and tap aluminum to "pintch" the cards in your desired location. I can do this for you (after some discussion) for a small fee (.1 btc)  They are leaning excessively because they aren't tightened down at all. Heavy washers and hex nut/jam nut are included to secure the allthread to the base. The fan cover (pictures in thread above) is included as well, although you will need to use your own 120mm fans and grilles. No hardware is included in this deal, not the power supply, not the mobo, Nothing! You are purchasing just the stainless case, standoffs for mobo mounting (special, don't loose!) cover for 1 atx power supply, 2.5" HDD mounting bracket, and hardware/brackets for riser cable use.    Please pardon the dust!  Accepting any reasonable offer, honestly don't know what to ask for this thing! I only ship UPS, and with my rates I expect less than $10 to ship anywhere in the US. Please PM for an exact quote. I don't have a problem with escrow, and can provide some history for myself if required. Thanks for looking, and please feel free to ask questions!

So I diverted my 7870Ghz from bitcoins to try my hand at litecoins, right now I'm mining on ltc.kattare pool using CGminer. I run the two setx commands (sync objects/max alloc) then my bat file. Running tc 16384, 915 clock, 1250 mem, 1 thread, 256 work size, 2 lookup gap, and 19 as an intensity gets me around 380k in CGminer.
But, the GUI of the pool I picked shows my hashrate at 420k, what gives? It's shown it high for some time now, so I don't think it has to do with averages or anything. Running 19 as an intensity cripples the computer, is it possible the hashrate picks up once I walk away and leave the PC headless? It's a fairly decent rig, old FX-8150 and 16GB of low latency 1866 ram...
Should I trust the miner, or the pool?
Thanks for looking!

So I was using an online wallet, I tried to transfer my coins to my local wallet and everything went well at first.
But then it got weird, the same transaction showed up, 15 times. The original transfer was for .53xxx something coins, so I actually received 7.95xxx coins total which is one hell of an oversight.
I see 520+ confirmations on each individual transaction, so I guess these coins are mine now?
I'm just trying to figure out what happened as I intend to return the missing coins, though nobody has asked yet. I don't want to be out of my own coins if these 15 transactions somehow show up as bad however. When can I safely say these coins are mine? As soon as bitcoin-qt tells me they are good?
I'd rather not mention any specifics, but it is a reputable company who's coins I'm sure I'm still holding if that makes any difference.
Thanks for looking!

Is there a market for bitcoin mining investment? I mean I already sort of have an investor in my current mining project, but he's just a friend (my boss haha!)
I have access to lots and lots (200A service 440 3 phase Cheesy) of very nearly free power, and I'm set up in an industrial building so heat isn't really a problem. I just picked up a dirt cheap 7870 a few days ago and pushed it to 450mh/s pretty easily, and I've been running a 3Gh/s 7970 monstrosity for the last few weeks. (I've got uptimes in weeks now, ha!)
If such a market exists, where would one look?
I know I posted this in the newbies section, that was a mistake!

Hello!
I have 4 7970 ghz editions on a gigabyte g1.sniper 3. Everything worked fine for some time, but now every time I try to start cgminer my system restarts.
So, first off I removed some cards. Two will work, but three or more are no good. All appear to be just fine on their own, so I'm not sure any cards are bad. I've moved them around the 4 pci-e 8/16x slots and they will work in any slot, so I don't think my mobo is bad.
My motherboard is specifically designed to run 4 cards and I'm doing so without risers (I would not advise this.) Powered risers are not needed, my board has a sata input specifically for externally powering the pci-e rails.
My power supply is a 1300W Rosewill, which I figured would be enough to run this thing. All I've got running is the cards and a sata SSD, no fans, no optical drives, nothing.
I guess I should mention that the 4 cards do just fine idling in windows, it's not until I load them up that things go south.
Anything else I should try?
Thanks for looking!

I just bought 4 7970's at newegg, and I got 4 codes for games, bioshock infinite and crysis 3. Where would you go to sell these and what would a good price be? I have no idea haha!
None of them were scratched off or redeemed, either.

Hey everyone!
I'm having a problem with 4 8x to 16x riser cables I ordered online. I can't get them to work, half the time windows refuses to boot and the other times it causes artifacts and device manager codes (not enough resources to start?) If I run all 4 on risers I can detect and use the first one, but it's crazy unstable. Usually loops, always restarting around the time PCH DXE Initiation started which is odd because I've disabled mostly everything I don't need in bios.
My motherboard is made to run cards like this, has 4 x16 slots that all work at 8x with my ivy processor. It has a built in sata plug that is described as for adding power to the pcie rails with three or more cards. All 4 work pretty well directly in the board at 8x speed, they just get hot! 1300W Rosewill powering it all.
I've read about changing pcie latency in the bios, but my board doesn't seem to have an option for that. My risers are unshielded and unpowered, should I try to add power/shield to them even though I know the motherboard has more than enough power?
Or did I just get a crappy batch? I've seen pics of guys running these cards unmodified, so wtf!?
This is 4 7970 Ghz, gigabyte g1.sniper 3, i3 3220. OC to 1150 gets a steady 2800MH/s, but temps are low 90s open bench with a very high velocity external fan.
Thanks for looking!

Hey everyone, I just finished building my first mining rig, thought I'd post it up here and see what you all think  How it started...   I didn't take pictures of bending it up. Press brakes are pretty damn intimidating, no distractions lol Testing for fitment!   I managed to get everything right the first time around! The components...  Gigabyte G1.Sniper 3 board. Z77, 1155. Gotta love all the pcie bandwidth! Intel i3 3220. Probably overkill, but I want to use this for other things occasionally too. 16GB of some off brand 1600 ram and 4 gigabyte 7970 Ghz editions  Testing out the nut riveter and standoffs.  The power supply, 1300W. Lots and lots of PCI-e plugs!   Dang, that's gonna be hard to keep cool....  My "idea" of a solution...  Cable ties, built in so I can lightly pull the cards apart.  Fan grilles in a few choice spots to keep cables away from fans. I split the chassis fan headers to power all these fans, this board only had 4. Oh, and a couple of baby resistors to make it all go. Anyone familiar with GM's early vats lol   I hate these stupid intel fans. I've built at least 6 machines with these heatsinks and I've never been able to reliably use the built in wire ties!  This thing is a gigantic piece of crap. Unfortunately my ol' trusty Maxtor died on me  And finally, a little results...  Damn!! Too much heat, not enough room to get rid of it! Three of the 4 are throttling at around 95-97 degrees. The one on the end manages to get 630-640 at stock clocks, -v -w128 in guiminer.  And with a bit of clocking... I can't get any higher than 1175 stable right now. At those clocks I'm averaging around 680. I'm hoping for a little more when I get these spaced out and cooled down a little. So, my new plan of attack is going to be spacing these cards out. I've ordered 4 8x to 16x cable risers, 8x because that's all the bandwidth my processor has for each. I know I don't need any more than 1x for mining, but I want to use it for other things too haha. Even crippled up she's still averaging around 1900 MH/s. I've got the top three cards severely underclocked right now. Any recommendations to increase that are greatly appreciated haha Stay tuned, interesting things happening when the risers decide to show up  I just realized that the lights are flickering in my living room because of this beast! Good thing it's going to run in a machine shop, free power!
