What kind of case is that, and what temps do you see on your gpus?



LianLi v2000b; 4x Asus 5870 on a 990FXA Gigabyte board with a opteron 145; Powered by a Corsair HX 1000w.
They were downclocked to about 750 - 800/110 and undervolted...

I don't remember the temps but they were in-between 85 and 95° C. That rig was pulling around 800w out of the wall plug.
Overclocked to 970/110 (and more) the rig would pull more than 1.2kW. The NT is really good, it survived heavy OC for a month Wink


Maybe ill find a pic of the stats somewhere.

eeeshhh...  Two risers daisy chained like that?  IDK if I could do that myself without worrying like crazy.  Then again for cards that draw less power, this may be less of an issue.

It never gave me trouble, tried with 3 to test it, worked like a charm, no errors, wires not getting hot.
I'm keeping the cards at 1,2 Vcore max, so they don't get that hot.

Yup, they are the only cards that survived.
My other 4 cards have had bad, broken fans, are RMA'd, etc.

I only kill the dustbunnies every 2 or 3 months with some compressed air.

Monday, hopefully I get my 2 new Gigabyte HD7970 cards (for my second rig).
Wanted to order Asus HD7950 but all sold out...

that's a good design, I am thinking something like this, my previous design isn't that stable for the "second floor" cars.

Yes- I am a terrible, terrible man. I'm not sure how I sleep at night.

In all seriousness.... Yes I'm wasting water, but if these weren't going then I'd be using a lot more electricity, which would have a similar effect to the eco system (nuclear power plant emissions).

Also, water is so so so cheap here that maybe my neighbors bill is like $0.25 more than normal....

You are also playing devil's advocate BR0KK, if you were really that worried about the ecosystem, then you wouldn't be wasting all that power to run a 4 GPU rig....

PS: Shuddup ya damn hippies  Wink (joke)

Nuclear power plants emit almost nothing.  They are required to by law.  Coal burners on the other hand release more radiation in an hour than a nuclear plant is allowed to release in a whole year.

Tested with one old XFX for an hour and it works.
Now I wait for my 2 new HD7970's.

The coolest part is I can monitor it remotely, and it has several temp sensors and is set up to shut down if it gets to hot.

Care to share your remote monitoring and auto-shutdown strategy?

2x Gigabyte HD7970 Smiley




my first rig (2x7970) give me 735Kh/s on W7, driver 13.1, cgminer.
But secon give(2x7970)  me only 570 Kh/s.
Which setting do you use?

35 BFL FPGA Singles Smiley (2 are broken and being sent back to BFL for replacements so there will be 37 hopefully within a week)


Full size: http://i.imgur.com/jKUnQfe.jpg

All were purchased used through these forums... your unit should be above (other than the broken ones) if you sold me one. :p
Not pictured: 2 box fans, 4 large PC-style fans, a shelf full of more power strips and BFL power bricks, and the console (keyboard/mouse/monitor) for the host computer.
This is in a somewhat cramped basement so it was hard to get a picture with everything in it.

Unfortunately I can't take credit for the custom BFL enclosure at the right of the top shelf; this came with my most recent BFL single purchase. Wink (thanks!!)

Host computer is an Intel Atom machine (the box with the bright blue light) but I'm currently having a lot of USB problems (which could actually be due to the units themselves... maybe it's because they're all used, but BFL Singles can be such a pain sometimes) so I'm looking to replace it with a regular computer soon. 

I know that I could power the BFLs from ATX power supplies using custom cables, but it would cost about $1000 US in cables and power supplies, and the Single SC's will require even more power (thicker cables + more power supplies) so I'm holding off until BFL's ASICs are out before I consider alternative power supplies.

I'm considering removing the cases from the units on the bottom shelf and will probably do this if a new host computer doesn't resolve my USB issues.  It almost seems like BFL sacrificed some of the functionality of these things to make them look nice, which I think is a terrible decision considering the purpose of bitcoin mining gear. Wink

Next step: Set up an air conditioner for when summer comes around...

Work in progress:



Now waiting for the 2x HD7970 cards Smiley

that's a good design, I am thinking something like this, my previous design isn't that stable for the "second floor" cars.

I had some materials laying around, so the design was based on "hmm, what's in stock?"  Grin
And to think that I received a bit of mockery at the time for my aluminium and wooden crazy-rigs... I never set fire to anything in the end, even with the 12-GPU wooden shelf rig (the second - long since dismantled - only had Cool pulling its power from a single household supply...


This was run non-stop, 24 hours a day, 7 days a week for getting on for a year IIRC. Didn't ever turn the central heating on during the 2011/2012 winter - I even had to keep the bedroom windows open to let some heat out in December. Noisy, unpleasantly hot, and eventually unprofitable (until the recent insanity began).

Now I'm virtually all FPGAs and am desperate to get more hashrate (I'm a committed, but very small, miner), but FPGAs are expensive and only compete with GPUs on power consumption - in my experience (best hash per £ GPUs, so 5770, 5830, 5850, 6950 all with special tweaks; and a combination of Ztex's 1.15d and 1.15x FPGAs, so all Spartan-6 units).

I lost out on bASIC Tom even though I considered my due diligence pretty good; he had a record of delivering and didn't send off my risk analyst radar like BFL did. And whilst Avalon *have* delivered ASICs, I can't take days off work glued to my computer, propped up on amphetamines and repeatedly hitting ⌘R on the slim chance that I'll get onto the order webpage - and even then needing the luck to be able to actually *pay* and get a guaranteed build slot. I fear now is far too late anyway and Avalon have already sold their entire short production run, so it's 'start the process again'. I wouldn't be surprised if BFL go the same way, since there are too many rumours of chips not making the cut, and like Avalon they would only have a very limited number of discrete chips to package and test. With all the pre-orders, I'm sure I've missed the boat Sad

Sure, I have the option to spend another £5k on 25 of Stefan's wonderful little boards and build another cool looking rig. It will be ultra-efficient and use little power. But, like the current one, it only has around 5 GH/sec. The ASIC devices are looking like around 50 GH/sec for something around £1k to (probably) £4k. I had a paid-for ASIC order in along with the other early adopters, but unluckily my order was with Tom and not Avalon. So if the ASIC boat has gone, with terahashes of power in various states of assembly at BFL and Avalon (et al) already earmarked for customers, buying as many FPGAs as possible *now* doesn't sound like it'll ever pay off Sad And that's even if I could get the FPGAs in the first place. Perhaps I should sell my existing FPGA rig for Bitcoins and simply invest (buy and hold only)...

Anyway back on topic, aluminium and wood with upright GPUs on PCIe extender risers (daisychained!) has proven over a year or so (IME) to be the best 'cheap' design. No ducted air analysis, no dead spots, easy to keep cool with a single desk fan, components accessible. Paradoxically, it's quieter than a game-boy-spec-extreEEEMEEE!!!!11! case with clever fans and also the best orientation for the GPUs. Here's one I made earlier (August 2011):



...and what it evolved into (half of which is still running as I type...):



...so I give in to the rhythm, the click click clack
I'm too wasted to fight back...
