Man, that's a crazy dense and clean setup. Is that 5 5850's on each rig? I'd really like a close up


Nice furniture movers on the feet lol

If you got the x1 to x16, did you short the presence detection pins?

BTW Cablesaurus, those power, reset, and status led extenders are brilliant.

I bought these when I wanted to make a few rigs, but I ended up recycling old PC's so that never happened.

Two are from Micron.
One is from Samsung.

They are all 1 GB DDR3 PC-8500

I ran Memtest86+ and no errors were found after several passes. Mixing brands is not an issue.

1.65 BTC shipped for all 3 GB or I'm willing to sell individually for .5 BTC each + .35 BTC for shipping

paypal is also an option and I would be willing to ship outside the United States; however, shipping may cost more.

PM me if you're interested

He's talking about your house's electrical circuit, not the power supply.

Yes!


If one were to set up multiple proxies that for every few proxy IP's there was another account. That may defeat the pool-side detection, but for the ISP, it would probably look suspicious to have tens thousands of small packets going to the same IP every few minutes.

True, maybe someone could turn their farm into a password cracking service, but very few have this capacity as you said. I have a very modest dedicated operation myself and was basing my experience from using a lone GTX 460 with http://www.golubev.com/hashgpu.htm's rar cracker. If I remember correctly, it would have taken a month to get a 8-character password cracked and I most likely used a 12+ character long password. I was also using it on my main computer which made it unusable and therefore I stopped. Now because of mining, I have that card plus 4 5830's. I don't want to stop mining though just to crack that password; I want to get the last bit of profitability out of them with the current difficulty and exchange conditions. I sent the file off to http://www.thegrideon.com about a two weeks ago and haven't heard back lol.

lol limit 10 per customer. hmmm

Just don't forget that cracking a .rar file takes a long time with a reasonable password. As I have found out.

Well, now the $110 one is listed as deactivated. Again. And now they put $7.56 shipping on it. Thanks for all the RMA's guys...

$137.56 shipped one is still there if you're into that.

Between me and my friends, we had 2 unused motherboards with 3 pcie slots total. All we needed were better power supplies and gpus. We put one of them in my friend's desktop as an upgrade to his older graphics card so it's not running as fast as the other 3, but it brings our total up to 4 5830's.

$650 invested
1000 Mhash

1.54 MH/$ or $0.65/MH

^^proud of that.

They've been in and out of stock for the last few days too. Seems pretty random.

The xtreme version is still in stock and its been thirty minutes. Maybe they got a real shipment of them?

*I mean regular Display port vs the mini display port. They both have regular HDMI

and they are in stock FWI. Counting now...

Because it's extreme? Aesthetically, it has a full HDMI port instead of a mini and it looks like there is a slightly bigger vent on the expansion port. It looks like it has a slightly different circuit board. I know this has been discussed elsewhere, but I doubt there is much of a performance difference. Still not a bad buy at $130.

I was going to post something along the same lines. Tom's Hardware had done a test a while back to see how bandwidth affected gaming performance. they put scotch tape over part of the pcie x16 to put it into 8x, 4x, and 1x mode. If you've maxed out what the motherboard will assign in bandwidth, then you could try that out. http://www.tomshardware.com/reviews/pci-express-2.0,1915-4.html

Good luck mounting the cards (assuming you can actually get the 5830's). That riser cable is going to be a tight fit if you mount the cards normally. The power supply though, 650W is cutting it close. I'm sure it's high quality, but 5830's are going to draw close to 200W each if you overclock them (worth it).  I'd go with at least 750W or more with this. As I have found out, a dying power supply will take your motherboard with it. and sometimes other parts too.

I tried out the script and it detected that they were in stock, but curl gave an error that --ssl-reqd is not an option and did not send an email. I actually saw that they were in stock before I checked the forum and got a couple.

The space above the motherboard isn't too important; it's just how vertically compact you want to be. In a 42U rack, you can fit 10, 4U ones or 8, 5U ones. You may as well start prototype #1 with a 5U design, then tweak it from there. Even with 6 cards, there is more spacing than what people have when they sick 3 directly in a motherboard. 4 gives you a generous amount of space. You could compromise and meet it in the middle with 5 GPUs. This type of case though, will force a massive amount of air over the cards.

Unfortunately, we couldn't find the original sketches. I'll draw a few things out tomorrow. I don't have a scanner handy at this moment, but my phone does a good job. It's the summer and I'm unemployed. I've got plenty of time.


I'm going to build that case and store the internet when I get some money 

My cable has worked wonderfully for the past few weeks and hopefully there will be many more to come. Thanks for the prompt shipping!

Unfortunately I probably won't be ordering any more cables as I can't find a decent card at a good price to justify expanding my operation

I just wanted to suggest for you to look into making a longer cable. I realize that the 19cm is the longest it can be made without degrading the signal quality, but If hashing works fine with a pci -> pcie (max bandwidth of 2 gbit vs 4 gbit for pcie 1x) then this may work without a performance penalty. I would test this myself by plugging one cable into another and see how it performs, but I only have one cable...
