That's like the old Athlon XP's cpu's that had that fragile, tiny core sitting up on top. So many people would crack the chips not applying even presure when installing the heatsinks. One slip and they killed the whole thing. Have you had any that you could not resurrect? That looks great. It makes sense on the shutdown before it overheats the quickest. I would have never thought of doing that.
Pretty much. For four chips you want the star pattern or one to the left for maximum stability. Six chips you populate the top and bottom left. Seven and eight you populate the right ones, but by then you better have bottom cooling or the Atmel/FTDI will be warm warm warm. Three chips oddly enough is a pretty bad number. The heat sink can rock forward without a chip to support it and put a lot of strain on the two side ones. Which is why oddly enough I don't do 3 chip mods. C |

That looks great. It makes sense on the shutdown before it overheats the quickest. I would have never thought of doing that. Thanks! Here's a picture of the 20gh unit I just did:  Note the heat sinks on the FETs and the 1850's. And that I put chip 5 in the upper left; that puts it's heat load furthest from the FETs, and also furthest from the FT232 chip. And oddly enough closest to one of the temp sensors, so if you overheat it will shut down the unit before damaging the board. Little things I have learned during this adventure. I wonder if I'll do similar stuff to the 300/600 boards. |

Good to know. Once I get my 74gh/s setup next week I might be ready to send one to you for the upgrade.  On a side note, I just finished upgrading jalapenos for two clients: One with 4 chips and the other with 5. Both went well, and are hashing away before I ship them out.
If you would like your jalapeno to be upgraded, please let me know. Just buy chips off Ebay, the guy LentBT sells excellent chips and I have not had a problem with one of them, and send me your unit. My current rates for labor and materials are:
.10 btc for 2 chips added (4 chip unit)
.12 btc for 3 chips added (5 chip unit)
.15 btc for 4 chips added (6 chip unit)
Note that +3 chips needs a better power supply (power it off an ATX or something like that) and +4 chips means you will be running with the lid off and the fan exposed. Going beyond 6 chips is really going to require serious water cooling. :-)

I have been enjoying mining MemoryCoin I just wish I could do it a bit faster. I only hash at about .822 h/m on my quad core AMD5557M.
I'm using mc2miner v.1e
Anyone have any tips for maybe getting a bit more out of it?
It's been a fun coin to mine though.

I have not been able to get your pool to work yet. It also won't accept my Doge payment address. Dogecoin is now on Quebec-pool.com! WE ARE GIVING 1000 COINS BONUS FOR THE BLOCKFINDEREarn more coins than you make on big pools since most of the coins are going to person with high hashrate. Server are stable on dedicated i7 server. Come try us! http://dogecoin.quebec-pool.com/ |

There is no shipping option for the address you entered. Please go back and check the address. Please make a shipping option to the EU. |

That is going be great! Can't wait to get it setup. My problem isn't Multiminer currently its U-verse LOL. Since my miners are all Avalons and Antminer S1's I have to use the Stratum Proxy, but since my Windows Server 2008R2 box is on a static IP for some reason none of the miners can route to it. Going to try again today but been trying to minimize any downtime with them so hard to make major networking changes without taking down all 8 miners.  I wanted to let you know that the Stratum Proxy will not be the only way to use an S1 or Avalon with MultiMiner in the next major update. In 2.6, MultiMiner will be able to automatically discover networked ASIC devices that allow RPC API access and show them as devices within the MultiMiner UI. |

Cool I will watch your ebay sale. I'm waiting for my BTC to clear coinbase then I am buying some gear. Canaryinthemine is a good person to use for escrow. There is also a list on the board of trusted escrow people. Are all of your miners blades? Here's my link to my eBay listing just so you all dont think im bull shit lol http://www.ebay.com/itm/ASICMINER-v2-Erupter-Blade-10-Gh-s-Bitcoin-Miner-In-Hand-free-shipping-/111265893431?pt=LH_DefaultDomain_0&hash=item19e7f6cc37I've bought a bunch of stuff of eBay befor but never sold anything so the big fat zero on my user name dont help getting bids lol Also theres like 50 listings for blades so its pretty bad competetion. If I dont get any bids I might post a listing on here for all my hashing power. I got 16 blades left and im still like not 100% sure if trying to sale now is the best idea but Im trying to save up funds to make a bigger investment in 1 th or larger miners when available for shipping.. (Not Pre Order) If I post on here I might try to find A trusted senior member as escrow... |

I wonder if the new hubs we got from razorfishsl would be perfect for that kind of overclocking? I bet they would. listen up wot is going on?
i have an antminer u1 and im using bfgminer 3.10.0
antminer is clocked to 2.2gh/s using code 0A81 however... it does not clock at that speed it just stays at the default 1.6gh/s
however... i can set it second best at 2gh/s using code 0981 and it stays at that speed.
WOT is going on?? doth the program not like letters in the freq code or?
clocking 2.2gh/s worked in cgminer however... i switched to bfg as i dont want to pull multiple erupters out of usb ports incase they get ted broken.
in any case... im losing 10% hash rate because of this WOT DO I DO should i continue with this ponzi scheme just wot do i do.
in any case wot is a hash error rate? if there is too much will the work be destroyed?

2.2 IS VERY DIFFICULT TO overclock to . you need a stud hub with very good power regulation. 2.0 is easy to do. so what is the hub that you are using? |

I wish I could go the hockey tickets alone are more than worth it.
I have a feeling Canada is going to take it again this year. They are so well rounded as a team.

Wow these look great! Where did you source your screen technology? I can't wait to get a bit of BTC to invest. |

Very cool. If I tied to add chips I would burn the whole house down. LOL Heh. I'm not going to Amtminers, this addiction has to stop with BFL stuff.
Speaking of which I managed to add a good 20gh of performance to my single/25 here. Now up to 48gh; I might add one more chip ust to bring it to a nice even 50gh. Yep, addict. :-)

Cool. I have my BiFury back at 5.8 working great. It was weird. Ok I have an odd question.
If I run BFG from the MuM folder and save my config from within BFG, when I then launch MuM is it using the config I saved in BFG?
No and in fact MultiMiner will detect config files, warn about them, and delete them as they interfere with some of the settings within MultiMiner. |
