im playing with overclocking my block erupters and it seems that cgminer is holding back the overclock.
the faster the BE is pushed the more cgminer seems to be holding it back from the speed it should be.
is there some sort of timing option that can be adjusted to help with the extra speed of the BE?
from what I have read the older client used to have some options but its not in the newer clients. any idea's?
PS this is only an issue for overclocked units, my normal ones are fine.
edit.
seems the "--Icarus-timing short" is possibly what I want.
im testing on a windows machine atm. how would I add this in minepeon?
I guess theres a file to edit.
Are you using the info in this thread for the over clock?
https://bt.irlbtc.com/view/241652.0It looks interesting, was thinking of giving it a try...
yep. put simply. change the crystal and the voltage resistor , add a fan blowing over them to try and keep the heat under control and then do the change to cgminer config and away you go.
currently got 4 of my 6 overclocked. and have more on the way. I will probably do all but one soon, I want to keep one as a reference for now.
I only have 13.5 and 16Mhz crystals atm . the 13.5 seems like a no brainer. not much extra heat and seems to run fine. the 16Mhz one you get a lot more heat and also need to worry about the current being supplied though the hub.
Thanks, thats VERY helpful. I'd been looking at the chart, and was sorta thinking about using the 16Mhz crystal. Now that I have your input, I'm thinking either the 14.32 or 14.75.
Do you think it's worth the effort/risk doing the 13.5?
if you are comfortable with the smt soldering then there is very little risk in the 13.5. I found not much heat increase and about 40Mh/s increase.
I would probably go a 14Mhz if I wanted a safe option if I did it again. I think 14.75 would be a good option but 16 is good if you can keep it cool. I didn't have the full set of resistors so to get the 16Mhz going I had to go over the voltage they are showing in the charts so its running extra warm,
having said that, I think this is getting this thread off topic. im happy to continue either via PM, move to the overclock thread or move to the minepeon site.
