--icarus-options 115200:1:1 --icarus-timing short=90



instead of:



--icarus-options 115200:1:1 --icarus-timing 3.0=100



Should provide most BE users with a slightly higher overall hash rate, more Accepted shares and a higher WU value to match.



...



Inspired by this amazing thread (and some other homebrew projects that I'm currently working on):











These are 4 'stock' USB Block Eruptors running off one 4-port USB hub with the 'best' tested settings I could find.



The avg: An all time average hash rate - appears to be doubled in some respects, which is somewhat questionable, however U: The Utility defined as the number of shares / minute - and - WU: The Work Utility defined as the number of diff1 shares work / minute (accepted or rejected) - appears to be quite a bit higher. Mine has increased from 18.8 avg to a steady 21.5 (up from 19.3 in this early screen shot). The U value starts lower, but has now exceeded the previous avg.



--icarus-options 115200:2:2 --icarus-timing short



Can be used on a dedicated mining PC with good CPUs for increased performance.



--icarus-options 115200:2:2 --icarus-timing short=90



Can be used on slower PCs that are also in-use.



EDIT: The --icarus-options 115200:2:2 is unlikely to give most users more Accepted shares, depending on your set-up and the pool.



N.B. I've tested these settings on windows and linux on both Bitcoin and Peercoin Pools. A single Block Eruptor mining PPC on a pool is currently reporting 768 MH/s (although it seems to range from around 448 MH/s to 665 MH/s) with the above settings.



IMPORTANT: I'm currently unsure if these settings will decrease the life of a Block Eruptor USB using standard cgminer.



Free CPU is essential for these settings. I'm also still testing if the number of accepted shares against rejects and hardware errors is really beneficial long-term.



I have a moded build of cgminer 3.1.1 (not the one pictured) and a moded BE that appears to be running at almost 1.5 GH/s - stable. If the device survives into early January 2014 - then I'll consider documenting the modifications for others to use.



Cheers!



Additional tip for windows users: go to Computer Management (My Computer) > Device Management > Ports (COM & LPT) > Silicon Labs ... (COM1) , (COM2) etc. > 2nd mouse button click > Properties Tab > Select: Bits per Second 115200 > OK and repeat for each mining device. Then start cginer again.



I've set my windows miner ports to the maximum 128000 - cgminer overrides these 'default' windows settings, but with the ports default being 9600 - one might as well at least match it. You can't and don't need to go above 115200 in cgminer as this setting is the maximum, but it is windows afterall.

Mine are using the OP's configuration (minus the custom cgminer) and are holding steady at about 397MH/s.









Most setups look more like this:



Mine will too - eventually.

I don't know about OP, but I've found that one of these makes them cool enough to touch without any difficulty. From what I've seen from others, its a pretty standard fan to use on these setups. Newegg is currently out of stock, but they're also available on amazon - for about twice as much.Mine are using the OP's configuration (minus the custom cgminer) and are holding steady at about 397MH/s.Most setups look more like this:Mine will too - eventually.

Has your WU value increased ? Are you getting more hardware errors than stock settings ?



Thanks.



I am running with those values.

Before this, I was using bitminter's stock software, as I found it gave be better results than BFGminer, so I wasn't tracking my WU.

It looks like I am getting more hardware errors than stock, but tracking shows that my overall stats have gone up by about .1-.2 GH/s.



I'm interested in seeing what it will look like with a modded cgminer.

That is a sick set up! (The 4 USB blocks with a USB fan) That is a sick set up! (The 4 USB blocks with a USB fan)

Agreed - my miners are still showing the correct hash rate at my pool not the 'overclocked' rate and I left them running for a good 8 hours with these settings.

Is that according to the pool you're using or the mining software?

Is that according to the pool you're using or the mining software?

That's an interesting question. I'm only able to see reporting from one of them (mining for other ppl right now too).



Miner shows 500-550 Mh

Pool live stats show .5 Gh but exactly 2x the submits the software is reporting

Pool history shows payouts for .3

Pool used: Bitminter



Tried another pool, and it's showing 100-250 Mh/s, so I don't think it's accurate.

Pool used: miningpool.co



I'm going to wait a couple days and try more of them in a larger batch. That's an interesting question.
