My newest addition to my collection of rigs, my rig at work.
How does your boss like you running a rig at work? I wouldn't see the problem. It's probably near silent because of water cooling.

interested in the micro sd adapter. you could probably fit it in a standard envelope with a single stamp, though I would probably put it between 2 pieces of paper or that thin brown cardboard stuff and tape it sealed so it doesn't wreck the envelope.

Hmm.
Spend $500 on a 680 GTX and get 120 mhash overclocked.
Or...
Spend $250 on a 5970 and get 650 mhash undervolted.
HMMMMMMMMMMMMMMMMMM............
If you want to use square wheels on your vehicle, then by all means... it's not going to be the most efficient or fastest route though, and people will probably point and laugh at you or give you weird looks. "Yeah, I got square wheels, but I can still make it to work! I only have to pay half my paycheck in gas too!"

I'm getting closer and closer to putting down an offer on the rosewill...

|

Don't know whats so lowball about it... <.< I've bought 4 5970s in the past month anywhere from $200-$250 shipped. I just offered what I thought was fair.
|

I offer $120 shipped to 54501 for 1 5870. i'm pretty stiff on that.

I'm in the process of trying to build a mining rig. I had everything lined up and then bam, someone bought the motherboard I wanted before I could. This raised a tonne of problems as the next cheapest motherboard I could find while only about £10 more, meant I needed a CPU which cost £30 more and RAM that cost a few £ more. This made the venture seem unprofitable for me.
Can anyone suggest some good cheap motherboards which can be bought in the UK and are good for mining?
Thanks!
well if you have cpu/ram that worked with your mobo in mind but doesnt work with the other one, then it's kind of important to tell us what cpu and ram you're using, or the mobo you wanted. otherwise nobody knows what you want

Have you tried flashing the VGA BIOS? Not sure what you'd flash it to though. Just dump the current one and see what it is, and if it seems horribly different, try looking on one of the vga bios sites (i think techpowerup has a database?) for the closest match.

You may be right since they aren't sold already. Either way $80 is the price they are worth to me to just rot in the closet in case I need them some day... it is what it is... Don't put them in the closet. At least loan/rent them out to a good home. I mean think of the poor lonely Mhashes.... Less mhash on the network = bigger piece of the bitcoin pie for me! (smaller difficulty). I say keep them offline.

2800x1880 resolution? That exists on a single consumer-level display? Can I get a similar PPI on a 30" desktop screen please?

well if his name doesnt tell you anything Doesnt for me. Mind explaining?

Do you have a Core 2 Duo E4300/E4400/E4500 (or something dual core and compatible with my Biostar G41 DVI Motherboard) and/or a cheap LGA775 compatible heatsink available to sell?

Figured I'd crosspost here to get a better chance at selling this. I am selling an Intel Core 2 Quad Q9550 CPU only. It is a 4-core CPU. It was a pull from my main PC, which was since upgraded with an i7-3930k. It was cooled with a liquid cooling loop. NOTE: This processor was LAPPED! There are no identifying marks on the face of the processor. This was done to improve the ability to cool this processor. The heatspreader is still there. It is just bare copper now instead of nickel-plated like how it normally retails. Again, there are no identifying marks on the CPU itself, however, It will be detected as an Intel Core 2 Quad Q9550 and operate at 2.83GHz (8.5 multiplier with a quad-pumped 333MHz or 1333MHz Front Side Bus). Make sure to double check that your motherboard supports this CPU. I have 2 other computers in this house that use the G41 chipset on the motherboard. This CPU works with one of them, but the other computer is incompatible with CPU's that have a TDP higher than 65W. The TDP of this CPU is 95W. It is important that you do the research yourself to find out if your computer will accept the Q9550 CPU. I have it on eBay for $170 shipped to US48. For forums members though, it's $155 shipped to US48, payable with equivalent in BTC (negotiate an amount at time of sale) or Dwolla. I might do paypal, but the risk is on me. International ship (including canada) will cost the actual shipping amount minus $5. You are responsible for any customs/taxes incurred. Picture below is not the exact processor you will receive, but it looks identical. It is currently sitting in the living room computer, which is working as a single GPU miner (radeon 5830). The heatsink I have on it (Thermltake Big Typhoon) is impossibly difficult to install/uninstall, so that's why I'm using a placeholder picture.

I'm still interested in the rosewill 1300W, but also still waiting for money to come pouring in from sales of other items Free bump nonetheless

Wow... Lots of high offers in this thread. I was interested, but you guys are WAY above my threshold. I'm out before I even began.

It probably contains 1.2g of unobtainium and will run until the 2nd coming autonomously! I guess what I am asking is does it include wifi or a ethernet port or does everything happen through the USB? Does it need a controller application on the PC that it is connected to? Again... would like to purchase for novelty reasons. If I was serious about mining I would be taking out a rather large loan LOL Extremely likely to run off of USB and require the usage of an included AC to DC power adapter. Will also likely make a large chunk of money the first month or so (3.5 ghash right now is about $500/month if you sell the coins you mine).

Is there any graphics/video cards coming out any time soon that would be good for mining? I'm thinking about building a rig with two AMD Radeon HD 5970's and I don't want to spend money on those cards if something better is coming out in the next 6 months - one year. Thanks -KCK402
5970 right now can be had for about $250-325 used and will do about 650-700 mhash when undervolted, and 3.2 mhash/j. Hard to find in good shape. 6990 is about the same as a 5970, but memory can be difficult to underclock, which means more electricity consumed. Has 4% less hashrate clock for clock than a 5970. I do not know how much power it uses. Price tag is probably about $300-400 used. More common than the 5970 but not by much. 7970 is a single GPU card. Retail about $420, or $400 if you're lucky. Possibly $375-350 used. I believe you can push 3.5 or higher mhash/joule.. Maybe 500 mhash when undervolted, or 700 with stock volts. Readily available. 7990 is not yet released. It will have 2 7970 GPU's on one card. Projected retail will likely be in the area of $800-$900. Assume a slightly higher mhash/joule and roughly double the mhash of a 7970. Probably due in 1-3 months.

I've used 1100-1300w server PSU's, that I've bought used and cheap off of ebay, such as DL740 1100W for like $20 and DL570 1300W for 50$. They were the best bang for the buck, if you're going on cheap. And I've got to play around with custom connectors, soldering and wiring, but that was lots of fun. The 1300W is a noisy bitch (as in airplane takeoff noisy), but I've managed to slow down it's fans to a bearable level, and still kept the PSU cool enough to drive 3x6990 880/150 24/7. Still, you don't want to be in a same room with it, or in a same building that is . 1100W is cool and quiet, just runs whatever you throw at it, like 3x5850+1x5870. There are used Dell/Alienware 1100W ATX PSUs cheap, like this one here, but I/ve never used them as USA is too far in shipping for me. What would you charge to turn those high power server PSU's into something a miner could use to power their graphics cards? I saw some big 1000+ server PSU's on ebay for cheap too but I can't find any useful connectors for them. I really wouldn't expect to pay more overall than a standard compuuter power supply.

I'm just going to copy paste what I said in an earlier thread about fixing busted fans. It may breathe new life into your fans, or they may be done and need replacement. Not necessary to replace the fan. I just bought a 5970 for $200 shipped that had a bad fan making loud noises too. Do what I do and take the sticker off the face of the fan and drill a TINY hole about 3-4 mm offcenter. Stop immediately when you feel the drill fall through. Put in about 5-7 drops of 3-in-1 multipurpose oil, wipe up the excess really good, replace sticker (or put a small piece of packing/invisible tape on the hole if there is no sticker or the sticker is ruined). Hand spin it a couple dozen times. Bam, you have a fan that performs as if it were new.
This works for reference blower type fans, or the regular fans on non-reference cards (or any other DC computer fan really). Done this to about 6 different fans so far, all work like a charm.
