I'll see what I can do; but I'm not currently certain what osc6 cgminer is running at. I can see a '54' listed next to the name; so I'm assuming 54.

With CGminer running on Slush, my average over 10 rounds was 3243MH/s

With BFGminer running on Slush, my average over 10 rounds was about 2600MH/s; however I'll run this again with the osc6 set at 54. If I see a big drop in my average hash rate, I'll switch back; as the Nanofury is currently my heaviest lifter. At least till my order from Hashrate store turns up...
Cgminer is not changing osc6 dynamically. On startup you can set it with --hexmineru-frequency
It is making 2.5gh+ stable per stick assuming everything else is ok osc6 is at 54 by default. Your score 3+ GH is a lucky one Wink  you need at least 24 hours of mining to compare results .
If you are in doubt about hash rate you can always use accepted shares formula as suggested by Kano and double check accepted shares cgminer stats and your pool stats

I was finding that I saw larger numbers of 'frequency drop' messages the longer that BFG ran; reducing the oscillations seemed to reduce the number, but consequently reduced the hash rate.

Using cgminer, I'm seeing a higher reported hashrate both on cgminer and my worker on Slush's pool. I'm seeing a reported 3558MH/s on the worker; but that's a combined rate for the Nanofury and two USB Block Eruptors. That figure is a definite increase over what I was seeing before; which was closer to 2800MH/s

I think I probably need to do a lot more reading on the subject, but I'm definitely observing an increased hash-rate on the worker.


hmm. interesting.  same amount of runtime?

try each at the same osc6 for a day each and report back if u dont mind plz  Smiley

I'm seeing considerably higher hashing rates on cgminer with patch, than I was seeing with bfgminer.

With bfgminer, I was seeing 2-2.45GHs and I had to vary the oscillator between 50 and 53 to reduce the number of 'frequency drop, resetting' messages.

With cgminer, I haven't had to adjust the oscillator and I'm seeing between 2.5 and 4.3GHs. 4.3 is a rarity, but it does tend to average around 3.2GHs. I've seen 5 second averages hitting 4.5GHs!

I'm quite impressed by the performance increase. I also haven't seen any of those 'frequency drop' messages.

For reference, I'm running cgminer in an Ubuntu 12.04 Server VM, running on VMware ESXi 5.5 and the Nanofury is connected to an Orico 10 Port USB 3 Powered hub (12V 4A power supply). It has a heatsink and I have a USB powered fan blowing over it at all times. It's cool to the touch; so I don't think I'm seeing heat problems with this setup.

Thanks to the producer of the patch! - Nice work Smiley

the 5 second avg means nada. its based on returned nonces over 5 seconds. hell you could get a work item where all 2^32 hashes returned a diff1 share.
but you need to compare bfgminers utility hashrate 3rd column after several hours running


edit: now that has me wondering what the (unrecorded) record is for most diff1+ shares in a single work item

I have used bfgminer for a while and I noticed a lot of messages similar "drop of frequency detected - restart". I have seen this on all my devices. Tried different things like dropping bits down to 30, active cooling, different powered hubs - no difference.

Did anyone else see something like that?

I switched to cgminer, so no problem, I am just curious.

Those messages are used for the dynamic clock/timeout detection. If I remember correctly, it uses received nonces per time period, figures in hash speed based on osc6. Or something similar

I switched to  "patch to cgminer 3.8.5 rev afe7710858e4ce28bb60f6ae6e167a18d687634f" as mentioned in https://bitcointalksearch.org/topic/m.4086475

or in short:

Yes :-)

The rar you mentioned contains a patch and the firmware for openwrt.

I downloaded cgminer in correct version and compiled it on ubuntu and debian using the patch and ignoring the openwrt files. Snippet of my history:

wget https://github.com/ckolivas/cgminer/archive/afe7710858e4ce28bb60f6ae6e167a18d687634f.zip
unzip cgminer-afe7710858e4ce28bb60f6ae6e167a18d687634f.zip
cd cgminer-afe7710858e4ce28bb60f6ae6e167a18d687634f/
wget http://technobit.eu/0_1_3.rar
unrar e 0_1_3.rar
patch -p1 ./autogen.sh --enable-hexmineru
make

That is what i wanted to hear Wink
Thank you

* openwrt updated to r39151

Cant get this working :/
Why?
Grab a tplink and try it in case you are not able to compile. I can tell you it works perfect 2.5Gh per usb stick - marto's ones

Just wait a little while ckolivas has received the nano fury i sent him and is working to incorporate support for it.

There's also problem with maturing parts (mostly capacitors). Old laptops rather have standard electrolytic aluminium caps. Those are drying  fast and power on USB ports become very noisy. I had few problems with that on few laptops that was older than 3 years... Extreme case was laser mouse that was consumig ~50mA and that was too much, and mouse was working in random pattern Wink

Hey I really love the Nanofury Design and thank you for putting it out there for us to use. I just got a small batch of Nanofury .7 "Icefury". It runs really great on one of my desktops, but on my laptop and other desktop it runs for about 10 minutes then fails. Any idea what has happened?

I am using BFGMiner 3.8.1 and have also tried 3.9.

If it works for a while and then starts misbehaving I'd say most likely it overheats. Get a small fan blowing at it and see if that will make any difference.
Also, when most electronics get hot they start using a bit more power - and at that point it might be getting beyond the limits of your laptop's power supply (but most desktops can tolerate higher power usage and that's why it works there). Try it also with a powered USB hub.
If you don't have an infrared thermometer handy you can start by lowering the speed by one or two bits and see how that changes the situation - at lower speed there will be less heat (and lower power usage).

they all use a 2 layer pcb correct? none use a 4 layer?

Yup - all are 2 layer (from version 0.0 till 0.7 inclusive). Actually 0.5 and later have been optimized and don't have any tracks on he back side - which serves both as a GND plane and also a heatsink.
As a matter of heatsink - I was actually surprised how efficient that was - I ran a bunch of miners last night without any cooling whatsoever - no heatsink, no fan, etc - and they performed pretty nicely at 48 bits (1.7GH avg) at room temperature of around 28C.
