heh heh heh

I've seen some people people push the 300 MH mark, but you have to overclock past 875 and I'm not sure if we are comfortable doing so. Right now we are running these flags on phoenix miner: -k phatk VECTORS BFI_INT AGGRESSION=12 DEVICE=0 FASTLOOP=false WORKSIZE=128 with sdk 2.4. What are you running?

I just got this picture from my friend and felt the need to post it. This is our first rig. This is a really old (beige) case so we had some holes to cut for it would work for its unintended purpose. We cut out a hole in the bottom so the gpu fan can breathe, a hole in the back since there wasn't one there, a hole to allow the power supply to fit, another for its cables to reach, and a hole in front to make that fan's life easier. The wood blocks were so that air could come up from the bottom hole, but I don't think this will be upright anymore.

Right now my friend is working on getting the second gpu working. About to try jumping the pcie x1 pins (edit: success!). Both cards are 5830's. The computer on the right is a single rig with another 5830 and we have a fourth card in my friend's desktop. Dedicated ones are overclocked to 875/700 (we're using linux. Can't seem to go any lower on RAM, but we're satisfied where we are right now) and are getting 265 Mhash/s each. When this one goes online we should be getting just over 1 Ghash/s!

K'nex. win!

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
