I mined at btcguild, triplemining and st Eligius pools, they are stable and reliable pools. But then I read on bitcointalk about a new pool: CKPOOL made by: ckpool code by ckolivas and ckdb code by kano.
You can mine at http://www.kano.is with PPLNS reward with (only) 0.9% fee. It has a great performance. I mine at this pool for some days now and I see it has better performance than other pools I used before.
If you are a real dare-devil: mine SOLO at http://solo.ckpool.org. This pool is awesome, you mine together with other miners to find a block but if you are the one that finds the block you will get the whole reward of 25 BTC!! (minus a small fee of 0.5%). It is anonymous, just mine just with your walletaddress as worker, no registration required. I know the change you will find a block is very smal, it’s like a gamble but it is fun and exciting.
Here is a quote from Ckolivas about CKPOOL:
Ckpool is a project by the cgminer development team designed to complete the circle between miners and pools from cgminer to ckpool. The bulk of the code work for this was commissioned and paid for, however I provided an incentive to the group commissioning the code to open the software up to all by charging less for free software than for closed code. Ultimately this should benefit bitcoin far more than me simply working on code for another pool. I intentionally chose to write most of the code from the ground up and not use external libraries to have complete control over all the code given past experiences of difficulty to debug failures in library code that was outside our domain with cgminer. The separation of the pool code from the database code allows the pool code to be ultra-scalable and extremely low overhead by dissociating any concept of share counts, user accounts, authentication, front ends, payschemes etc. etc. These can be as vastly different from the envisioned ckdb+postgresql+php interface as the administrator desires without any change to the core pool functionality.
UPDATE [NOVEMBER 1 – 2014]
The CKPool www.kano.is is doing great ! More miners joined and total hashpower had grown to 600+ THs and the pool has found 4 Blocks already in just 1 month ! So join us fellow miners !

Today I was wondering why the first 8 build OSM (One String Miner) only hash between 23 en 26 GHs. I measured the voltage input in the boards: 11.4 V !! The PCI-E connectors from the PSU “only” supply 11.4V instead of 12V. Weird, I will investigate tomorrow. I had 4 DIY-1 kits left, build the first one just standard: pcb + heatsink. For power I used a cheap 12V 10A PSU from Dealextreme. You can adjust the 12V power output on the PSU some time for some tests:
No thermal paste between PCB and Heatsink + Artic F8 Fan (very low RPM)
With thermal paste between PCB and Heatsink + No Fan We will see how temperate gets higher after x seconds
Today I received my One String Miners. Great design by C-scape and Intron based on Bitfury chips. I won some miners at an auction at bitcointalk.com . Ben Turas is selling these great miners, designed in the Netherlands, produced in Asia!
Check out his salestopic.
The OSM is based on Bitfury chips and each board contains 15 chips, hashing 25+ GH/s without heat sink and 30+ GH/s with heat sink. Each board runs from a single 12V supply, using ~25W.
I have 4 DIY1 and 4 DIY2 kits. This evening I build up the 4 DIY2 kits and build a small tower. Quality of the boards and other materials is high. Building was very easy. Screw the pcb to the heatsink, connect the wires to the powerconnectors, that’s about it. I used a BeQuiet PurePower 600W PSU I had laying around. Attached two fans, all in a temporary setup. 10 Port USB Hub is a Rosewill RHB-500. I used an ArchLinux PC, downloaded and compiled CGminer 3.12.3, turned on the miners, started CGMiner and it detected all miners. 3 miners were “ZOMBIE” at first but after just 10 seconds all boards were recognized and hashing. All works great with any issues. Temperatuur is stable with only 2 fans (in the most efficient position), 30 to 40 degrees Celcius. I haven’t tuned them yet so they hash around 25GH/s per board.
For now some photos, next few days I will do some more tests and tuning. I realy like these boards you should get some too!

This is a short manual how to install BFGminer version 3.8.0 on Linux for the Hashbuster Micro 20+ Ghash/s (bitcoin)miner. Tested on Debian Linux 7.2
Update Dec 20: newer version of BFGminer is out: 3.8.1 . Manual is still the same but you can leave out: Now we do a little tweak to prevent reinitializing errors,….
