Quite interesting.. Is it just me or does that seam like an awful little heatsink for that big a tank?  How many asic's / fpga's are you planning on putting into the tank? Are you going to be circulating the fluid via pump / fan? |

whats your cgminer string like? heres mine working with my icarus:
cgminer-nogpu -o stratum+tcp://mint.bitminter.com:8332 -u user_worker -p pass -S COM3

Nothing rare, but my two little USB erupters arrived today. Set them up on a shelf above my desk with a D-Link DUB-H7 7 port hub I got for $23. I quickly realised that they were reaching 70+ deg C temps when I was setting them up and the 2x 15 watt server fans really help (but they are running at 3.3 volts so they are essentially silent). Miners now get better temps of about 45 deg C (25 deg C ambient) after running for a while. Getting <1% hardware errors in bfgminer I might have to look at that later.
Is there any components on the other side of the PCB? Or is the aluminium heatsink removing heat through the PCB itself? Some micro-sized heatsinks might be in order for the ASIC chip on the top side in any case...
There were a couple of guys playing around with some clip-on heatsinks that reached the chips pretty nicely.. might be worth looking into. Just did a quick search but couldnt find the post . will look again a little later. |

So whats the latest news? - Everything set for the asic chips?

I'll offer the value of 4btc including shipping to dk if you take paypal transfer.

what kind of hash/s have you gotten from them?
|

Im sorry to say.. but I was this close to ordering this.. but then you add VAT afterwards.. i HATE that  another 24% on the price.. |

Having them push in was a thought about putting more airflow towards the back of the case - where the gpu's are.
Anyways i think its a matter of the amount of thermal paste - im thinking too little. will see when i remove the heatsinks tomorrow.
The sidepanel is on yeah, with a 120mm fan blowing cold air into the case.

Okay, so changed the thermal paste today.. AS5.. and removed dust from the fans/ribbons - with compressed air.. that didnt really do any good  Now the temps are as follows: GPU1 93 degrees C GPU2 86 degrees C - this is AFTER i underclocked both of them to 700core/525mem - lowest mem clock in msi afterburner for this model I changed the top fans to push more cold air into the case though. I know that AS5 is supposed to have a 200 hour "burn in" phase.. but doesnt this seem to be wrong? - im wondering if i put too little paste on the gpu maybe? |

That's a real shame, but seems to make sense in the current crazy ASIC environment. There's no sense in being late to the party if some of the other ASIC offers materialise at the end of the summer. Would be great to see bitfury ASICs on a CMx board at some point. Also, your litecoin mining hint for CM4 was cruelly inticing  . I'd love to see a scrypt miner from you guys if you can do it!! +1 The litecoin aspect is really interesting and could be a gamechanger in that currency. I imagine that would bring more success than an bitcoin ASIC would - seeing as theres a lot of run on the marked for those units lately. But noone seem to have been going forward with a litecoin setup - not in public that is. |

What about your airflow? Even with the fans, you have to make sure you are feeding cool air onto the cards, and that their is good exhaust as well. If you are running fans at 100% and still hitting 90 says to me that air flow isnt optimal and the hot air is staying around the card(s).
Airflow. Crossair Carbonide case, 1x 120mm fan in the side panel pushing in, 2x 120mm in the front pushing in, 2x 120mm in the top pushing out. I got 2x gentle typhoon laying around, but those are too loud even for the place i got this box sitting.. |

Hi Trillium. Thanks a lot for the reply. Im pretty sure it has to do with my OC'ing aswell. I just put them back to stock speed and it (GPU1) is already pushing 92 deg C. after around 10 minutes.. - And im running the fans at 100% speed. GPU2 is running at 78 deg. C. with the same settings. Im going to try and change the thermal paste tomorrow - got some AS 5 i'll try and put on. Can you perhaps tell me your string for running cgminer? - im having trouble getting it to run properly - as said, it just crashes upon startup.. :/ |

the GPU2 runs for about 25 mins un guiminer before it shuts down.

Hi
Im having some issues with my "re-use" mining rig.
My setup is an AM3+ cpu, gigabyte mobo, 4gb ram, 1200w gold + psu. 2x Powercolor 6870 cards.
Im trying to mine litecoins.
First off, Im still new to cgminer, but cannot get that running properly - just keeps crashing upon startup..
Anyways, I have tried both bitminter (which seems to work okay, but the actual hashrate isnt reporting the same on the website as in the miner..) and guiminer.
Guiminer works well for GPU2, for some time but then it just stops hashing and cpu usage goes to 0%
GPU1 doesnt work at all it seems..
Am I looking at some bad gpu's here? or whats the deal :s

Price per kWh | 2.5 DKK (~0.43 USD) Current as @ | 2013-07 Provider | EnergiNord Country | Denmark Minimum wages are ~16usd/hr for adults. So Thats around 2688usd a month - before our Lovely tax system that grabs a minimum of 40% - and up, depending on How much you make So yeah, FPGA / ASIC country here |

download drivers, use bitminter.com client. done.

Not a bad idea to use those plastic boxes as reservoirs.. at one point, I was considering Building a rig in my attic, and running the Water Down into my radiators in my living room to heat it without Water cost.. Could combine by running it Down first, then up into boxes like that .. should be usefull |

I'd love to see a pic of one of these stations with 2 PSUs and 6 GPUS.

Check your installed devices in the device manager. You should be able to find it in there..
I just installed the drivers from the page, loaded cgminer/bitminter and fired it up.. Did u try bitminter client?

Checked thermal paste/heatsink is still sitting properly?
