The past few weeks it seems like I always have a miner that is reporting all shares being rejected. Seems to only happen when I'm using slush's proxy. The proxy reports that share was above target.. Soon as I restart cgminer on the effected pc it goes away. I updated to the newest proxy and my miners are just using windows. Anyone know what can cause this?
Blame the proxy? There are no reports like this for anyone pool mining directly.

It seems the ASICMINER 300MH/s USB devices are Icarus look-a-likes (as far as cgminer sees them) and apparently I'll be sent one soon.
These things: https://bitcointalk.org/index.php?topic=195004.0

So ... this means I should get around to converting the last old driver to direct USB - the Icarus driver - so that then all the old drivers are direct USB.

Could anyone with a Lancelot or a Cairnsmore1 post a linux "sudo lsusb -v" of either of them for me please?
Thus when I have the code ready I can simply add the small definition required to detect each of them also.
Would also be good if (in a week or two when it's done) someone with each of the boards would be around to test the modified code.
I may also require a little more help with each if the USB chips are unusual in them or different to the Icarus (to get the correct initialisation commands) since I don't have either of those cards ...
Thanks to any who can help with this.

You might want to check for the code supporting dynamic clocking for Cairnsmore1 in bfgminer or the Modular-Python-Bitcoin-Miner. Cairnsmore1 with the dynamic clock firmware (maybe the most used out there) defaults at 150MHz although most of them can run between 210 and 220MHz (bfgminer limits it to 210 Sad ). You probably don't want to allow more than 230MHz in the code to protect the hardware and might want to have a lower configurable max with a warning in the FPGA-README.

Cairnsmore1 have USB stability problems (seems really picky about the voltage stability from what I could understand): occasionally they disappear from the USB chain to reappear moments later (I have 2 here one does that less than once per week, the other several times per day).
bfgminer tries repeatedly to reopen the dev file (probably similar/same code that is in cgminer) until it reappears, MPBM regularly polls the USB chain for hotplugging new devices so it doesn't have any specific code to circumvent that.

bfgminer doesn't work correctly on p2pool with Cairnsmore1 (doesn't seem to restart work when asked to) and gets less hashes out of my 4xIcarus (compared to both cgminer and MPBM), so I use ModularPythonBitcoinMiner for all my FPGAs currently.

I'll pledge 1BTC for dynamic clocking support and the ability to reactivate a board that disappear and reappear (I probably won't get much out of my 2x Cairnsmore1, but it would simplify all my scripts if I could only use cgminer for all my rigs).

Any possibility of integrating the work of CUDAMiner into cgminer?

https://bitcointalk.org/index.php?topic=167229.0

He managed to get nVidia cards to an "acceptable" (not as sucking as before) speed on scrypt mining.

It would be nice to have the same benefit in the cgminer architecture (since cgminer has a lot of extra features)

I think ckolivas said he would do it for donations.

A donation that starts at 1000 BTC and goes up from there, that is.

Here's the context.

I have MSI 7950 TF3 OC, gpu/memory/fan setting are working, but now GPU voltage, it still stay at default, I am trying to set
"gpu-vddc" : "1.013"

Have to use afterburner to set it right

That's what's known as the "I don't want to do it price". I have done cross platform code in CUDA before so I know what's involved. Plus you still pay more in electricity than you earn in coins mining with Nvidia GPUs, so it's a less extreme version of what happens with CPU mining. I'm sorry but cgminer need not support everything.

I'm totally for keeping CGMiner as simple as possible. I actually wonder if one day you will drop GPU support for strictly ASIC support. However, the higher performance of native cuda seems to be pushing the cards into the realm of slightly profitable. A 580 seems to push 280KH/s, which is about $1.25/day profit.

You might want to check for the code supporting dynamic clocking for Cairnsmore1 in bfgminer or the Modular-Python-Bitcoin-Miner. Cairnsmore1 with the dynamic clock firmware (maybe the most used out there) defaults at 150MHz although most of them can run between 210 and 220MHz (bfgminer limits it to 210 Sad ). You probably don't want to allow more than 230MHz in the code to protect the hardware and might want to have a lower configurable max with a warning in the FPGA-README.

Cairnsmore1 have USB stability problems (seems really picky about the voltage stability from what I could understand): occasionally they disappear from the USB chain to reappear moments later (I have 2 here one does that less than once per week, the other several times per day).
bfgminer tries repeatedly to reopen the dev file (probably similar/same code that is in cgminer) until it reappears, MPBM regularly polls the USB chain for hotplugging new devices so it doesn't have any specific code to circumvent that.

bfgminer doesn't work correctly on p2pool with Cairnsmore1 (doesn't seem to restart work when asked to) and gets less hashes out of my 4xIcarus (compared to both cgminer and MPBM), so I use ModularPythonBitcoinMiner for all my FPGAs currently.

I'll pledge 1BTC for dynamic clocking support and the ability to reactivate a board that disappear and reappear (I probably won't get much out of my 2x Cairnsmore1, but it would simplify all my scripts if I could only use cgminer for all my rigs).
Thanks for the lsusb - that makes the device identification part easy to get right Smiley

FTDI with: idProduct 0x8350
That's gonna mean that the initialisation code is probably gonna need some help from you to get the correct settings.

Heh I have never gone near changing the clock on the Cairnsmore1 coz I don't have one.

I have an MMQ and thus did end up writing my own clocking for it - that took quite a bit of testing to get it where it is now where it keeps the HW error % under 1% and seems to handle bad environments pretty well also (but not bad hardware - nothing you can really do with that Tongue)
The MMQ code was pretty much a complete rewrite anyway coz it didn't work and the clocking/timing code in it was pitiful - the devices can't be stopped without effectively wiping the bitstream. cgminer is the only one that actually waits for the work to finish and allows it to go idle when it overheats.

Anyone else willing to throw more BTC at me to add clocking? Smiley
(or has anyone yet given up of their CM1's and wanna give me one Tongue)
Getting someone else to test is a painful way to develop code ... and no I wont copy the code from the clone even though it was built on top of my own code ... all that timing code in icarus to allow different performance devices and different FPGA counts was written completely by me (but not the clock change code)

I actually wonder if one day you will drop GPU support for strictly ASIC support.
Yes well I'd like to but some crazy nut decided to code up scrypt support for cgminer for a fee he thought was "I don't want to do it" price, and that will keep GPU mining alive in cgminer. That's why I've raised my "I don't want to do it" price. I'm quite sure nvidia miners can't afford that fee. That and the ASIC hardware is far from being "available" just yet...  Roll Eyes

No problem Smiley

I'll stick to cudaminer with this nvidia card, and keep the ati's on cgminer

How much would it cost to have a flashing "Generating $1000 per hour." at the top just to fool the wives?  lol

Hi,

A number of us are getting CGminer lockups following stratum connection interrupted issues:
https://bitcointalk.org/index.php?topic=188533

The pool never fails over, and cgminer stops hashing and becomes unresponsive to keyboard input.

Any fix or workaround for this issue?



This is still an issue (though not happening since I've switched to a pool with a more robust stratum connection).

Any devs that can help? Or can someone point me towards the process to raise a bug report?

If you found this useful modest tips welcome BTC: 15noAopoPUcA4D4dTJihgDVE8axZh8VWia

Consider it raised, it has already been discussed but the solution is pending.

I have a Power Color HD7950 and I am unable to change the voltage (undervolt) using cgminer?

Core Clock and memory seem fine but voltage wont change?

On windows I can use the PowerUp Tunner program and change the voltage, but the mining machine I am building will be linux.

I have tried amdoverdrivectrl with the same results as cgminer.

Any ideas?

That's a new number.

Do you mean 7950?

A: Because it messes up the order in which people normally read text.
Q: Why is top-posting such a bad thing?

Quick noob question : I've set up multiple pools in the .bat file, and those pools mine different coins. I've noticed that pools that don't have stratum set up somehow... borrow the stratum information from other pools.

EVEN if it's a different coin ?! How is this possible ?
