I'm going to start cleaning up some old coins we no longer mine. If you currently have a balance of these coins, I urge you to cash out asap. In a couple of days they will be removed from the site completely (we can recover and send out balances after this point if needed, within a reasonable timeframe). The following coins are affected:
ALF
KGC
CSC
EMD
GDC
SXC
GLD
HBN
DMD
STR
GME
ADT
All of the above were mined at some point, but actual profitability results didn't live up to the formulas once coins were exchanged. Most haven't been actively mined in some time. Any questions or concerns just ask.
I would recommend disabling it instead... You never know, it may get active again.... |

Question about Vardiff.
Are each Share's Vardiff calculated or is it the last Vardiff value?
example,
50 @ 32 diff
20 @ 600 diff
3 @ 1000 diff
12 @ 400 diff
coin change.
So, are the diffs calculated on the last vardiff value or are they calculated separately?
last diff = 85 * 400 diff = 34000 shares
individually = 50*32 + 20*600 + 3*1000 + 12*400 = 21400 shares

anyone using Cuda miner instead of cgminer for hashcows?
if so what starting command line are you using?
this is what im trying to use but keeps just saying
HTTP request failed: Failed connect to 127.0.0.1:9332; No
json_rpc_call failed, retry after 15 seconds
cudaminer.exe" -d 0 -i 1 -l auto
-o stratum+tcp://stratum01.hashco.ws:8888 -O ****.1:****
since when does cudaminer support stratum? I think you need a stratum proxy to get it working... try guiminer-scrypt for the stratum proxy. then point to 127.0.0.1 for cudaminer while stratum is set up in the proxy. |

I have enabled the checkpointing server which basically helps stabilize the chain and the need for constant client updates.
Just wondering if PoW is now dead and PoS is only way to get more COL. With MuddaFudda's Silence on here, and Memecoin's avoiding to answer the question I asked him several times, Their SILENCE is Golden and COL is now ONLY a PoS Coin. So how come the Value is horrible? Nobody Trusts this coin? |

grrr i dont know should i move my 2mhash on LTC or stay on this pool? what is estimated for 1mhash here?
Today's data says we are slightly over litecoin rewards, 8% better or so. We are doing excellent with TAG in play... TAG's Difficulty being at 57 makes it hard for Solo Miners. |

You want me to overclock instead of undervolt? Now you're really confusing. I'll never hit 1060-1100 mhz on those chips with my lowered voltage, and I intended it to be that way. My voltage/clocks -- 3.27MH/J Your clocks -- 2.955MH/J Once again, you have no idea what you're editing. I've tried to help, but you're still so sure of yourself (even though you've obviously not disassembled the code to that BIOS). I've made national news for things I've done with video cards, but I'm sure you're still right.  Youppi! You made National News... unfortunately it was not World News. I am sacrificing 0.315 MH/J to be able to heat my house better. For some people, we need our HEAT to keep our house warm. What better way to heat our house than with Mining? HEAT and make money with it. Before I undervolted (or you thinking I am not undervolting), at stock BIOS with the speeds I am currently running undervolted, I hit 1700 Watts @ 2.9 GH/s (Digital PS handled it for a short time). Now I am doing 1250 Watts @ 3.329GH/s... So shaving off 450 Watts is not undervolting then what is? Yep, it looks like I have no idea what I am editing oh mighty BIOS god however, it looks like I found something YOU did not find... gaining Hash Power with lower power consumption. If you want to discredit this finding by all means please do. I am just happy I am able to run the 5 cards at the speeds I am getting. I do however credit your findings... you spent more time than I did disassembling the BIOS... Surprised you did not find the secret to gain more hashing power out of it like I did. |

P.S. This rig takes 673 watts (at the wall) to run because I *actually* undervolted it.
You are running 900 mhz gpu and 800 mhz memory.. no wonder you are at 673 watts at wall... set it to 1060-1100 mhz gpu and 1250 memory then report back with your watts at wall... Lets measure apples with apples now. |

Tried Hashcows for two days but I got a lot of rejects! (around 10-25% depending the coin)
I tried numerous pools and never had this problem before... Any idea ?
One of the major reasons is Hashcows jumps from pool to pool and when they do you shares drop and turn into rejects due to nothing to work on while pool moves to another coin. One thing that multipool does is gradually moves the miners without any rejects or very very low. Hashcows just slams on the breaks  also alot of alt coins have high rejects do to the low hashing going on.. i guess ? Actually I prefer Hashcow's method... I have collected some nice coin on some high diff coin. Usually hit it within the few minutes during coin shift... So end up getting some extra bonus high payout coins too. |

0.007 BTC per MH and day... this profit barely covers a 0.10 USD/kwh rate. I keep my rigs working because they heat my house nicely, but this is the only reason now.
How is your efficiency on your mining Rigs? I generally have 500 Watts per MH of hashing power, which translates to roughly $4/day in power at 11/kwh electricity rates. I got 3.320 Mh/s @ 1250 watts or 376.50 watts / MH power. Using 4 x 7950s and 1 x 7970. Impressive. You are measuring power draw from the wall, yes? Voltage and settings? yep... ranging from 0.962v, 1.003v, 1.008v, 1.024v, 1.080v thread-concurrency 40960 shaders 1792 and 2048 gpu threads 1 gpu engines 1060, 1080, 1095, 1100 gpu memclock 1250 and 1500 powertune 0 |

Hey guys, is the client all fixed now for this coin? I've been talking to the guys at Cryptsy and it seems they're pretty eager to to get this coin listed once the repairs have all been done.
I'm eager cause I hate holding 7 billion COL in some Chinese exchange.
So those in the know, is the fix complete, and are we ready to move on up in the world, from China to Miami?
Thanks!
It's fixed. Syncing is happeneing. It's pos only for now, I believe. "700 Billion Coins Total 5,000,000 per block halving every 50,000 blocks. Approx 550 billion mined coins and 150 billion POS possible. Huge overhead for big POS rewards." I don't think PoW is finished... We still have about, another 240 Billion coins left... unless this is no longer the case... 01:28:41  { "version" : "v1.5.0.0-col", "protocolversion" : 70000, "walletversion" : 60000, "newmint" : 0.00000000, "stake" : 0.00000000, "blocks" : 172570, "moneysupply" : 312389879404.17083740, "connections" : 17, "proxy" : "", "difficulty" : 0.17436570, "testnet" : false, "keypoololdest" : 1379911748, "keypoolsize" : 102, "paytxfee" : 0.00000000, "errors" : "" } |

GPUs are not Car engines... running hot or cold makes nominal difference.
You are quite wrong. Power consumption rises as temperatures within the ASIC increase (leakage increases because resistance increases). AMD's 28nm chips are extremely sensitive to this, and the power consumption climbs rapidly above about 73-74c. Go put 4 7970s in a rig, measure it at 60-65c and then measure it at 80c. You'll see 80-100 extra watts being drawn from the wall, even though the fans spun DOWN. Water cool the chips and you'll notice a pretty significant decrease in power consumption under load. Lastly, you'll notice that power consumption is *much* lower when you first start your mining software. Go measure it again after 15 minutes and be amazed by how much more power is being drawn after the ASIC heated up. Once again, the number you are altering doesn't change the power consumption on ANY 7000 series BIOS. I don't mean to sound pompous here and I'm only trying to educate, but I know what that value does and you clearly do not. If you had spent enough time reverse-engineering that value, you'd realize that it only changes the voltage reported by ADL (and it changes the voltage on cards prior to Southern Island chips since they had a function that translated the voltage value into the proper commands to send to the voltage regulator. The 7000 series cards do not have this.) Still drawing 1250 Watts and getting 3.329 Mh/sec. I have been running overnight. I will set the temp lower to see if that will reduce consumption. |

Anyone that have a successful undervolted 7950 bios file to share ?
It would be much appreciated !
If you want me to undervolt your BIOS, send me a link to it via PM... Donations welcome. |

DITTO, I would LOVE to see COL on here. |

I would think it is all a matter of timing between memory and gpus... since they are not overclocked to push more and produce lots of heat they work in unison. I was shocked too when I saw the results. If I tried to overclock while undervolted, it would then drop in performance. I think the bell curve gets shifted downwards as you undervolt.
Go measure your card's voltage with a meter before and after what you're changing in the BIOS. It isn't budging, I assure you. Your power consumption changes are either differences in settings, or you're measuring when cards are hot vs cold. I don't poke my GPUs with wiring... I can see if at the wall... 1250 watts @ 3.329gh/s vs 1480 @2.9 GH/s is all I need to convince me. GPUs are not Car engines... running hot or cold makes nominal difference. Here is my Before Undervolting settings.

1: Both at Intensity 20, Thread Concurrency @ 40960, Shaders @ 1792, lookup gap @ 2, Threads @ 1, powertune @ 0
Before undervolting, running 1090MHz CPU, 1500 MHz Memory
After undervolting, running 1080MHz CPU, 1250 MHz Memory. 250MHz lower on memory speed yet gained 115kh/s
2: Nor do I but it does not affect mem timing if you are using the memory stock speed of your vid card.
Gigabyte and Sapphires work great for getting good high hash rates. I had an XFX, was crap returned it.
Consider maxing out the Thread Concurrency as much as possible along with the shaders. It worked for me and getting great speeds. Scrypt is memory intensive so more memory it gets the more it can hash.
That is weird, undervolting normally only result in equal hash rate or lower. Maybe its due to powertune @ 0. hm... here is my cgminer.conf { "intensity" : "20", "vectors" : "1", "worksize" : "256", "kernel" : "scrypt", "lookup-gap" : "2", "thread-concurrency" : "40960", "shaders" : "1792,1792,2048,1792,1792", "expiry" : "2", "gpu-dyninterval" : "7", "gpu-platform" : "0", "gpu-threads" : "1", "gpu-engine" : "1100,1080,1100,1080,1060", "gpu-memclock" : "1250,1250,1500,1250,1250", "gpu-vddc" : "1.020,1.01,0.962,1.003,1.08", "gpu-powertune" : "0", "auto-fan" : true, "temp-target" : "75", "temp-overheat" : "79", "temp-cutoff" : "83", "log" : "5", "failover-only" : true, "no-pool-disable" : true, "queue" : "2", "scan-time" : "1", "scrypt" : true, "shares" : "0", "kernel-path" : "/usr/local/bin" } And CGMiner results. cgminer version 3.1.0 - Started: [2013-10-18 22:46:23] -------------------------------------------------------------------------------- (5s):3.350M (avg):3.329Mh/s | A:53296 R:5269 HW:0 U:9.5/m WU:3099.7/m ST: 3 SS: 265 NB: 15036 LW: 649635 GF: 190 RF: 52 Connected to stratum01.hashco.ws diff 237 with stratum as user swiftshoot.2 Block: cdc821b513950ac7...
