While they might not win any races, these sticks are really solid performers!
This past weekend I got my two sticks up to 306 MHz and 16 GH/s each (running on Y cables with the voltage tweaked up as needed). But I was still seeing a few HW errors on one stick (the weak one of the two). So I tweaked up the voltage on that stick one more time.
So now I've been running for a couple of days with zero HW errors. It's more stable than when they were running out of the box with the stock 150 frequency (8 GH/s) and no voltage adjustment.
Note that my voltage adjustments were not scientific. I've got a meter but I didn't use it. I basically increased the frequency, and when I started to see HW errors I just made very small adjustments to the pot until they stopped. It was all by feel, but it seems to have worked well.
Thanks again to sidehack and novak for making such a cool product!

If it's directly plugged into the computer, sounds like windows 7 is probably set to save energy.
Check under the power options and see if it's set to actively suspend USB and if it is turn it off.
While your in the power settings, set the computer sleep to never.
Will do thanks !

Is this on the Pi that you set up the other day and had a little trouble with?
What kind of hub, USB 2.0 or USB 3.0? Pi's don't like 3.0 hub's and are really picky with 2.0 hub's, because some of them will back-feed power to the Pi.

Tomorrow I will get novak's version to be able to get higher.
I want one !

Then you can use any hub 3/2, etc. Win 7 is a lot more forgiving on usb hubs. So pretty much no worries besides how much power they have.
I have been playing with 3 compacs on freq got to 250 on regular cgminer 2.9.2. Work rock solid. Tomorrow I will get novak's version to be able to get higher. Thanks for putting together a cgminer to get higher with these sticks!
I have a little bit of air from PC fan's blowing through and they seem to be doing very well.

Herbpean - what's your errors look like? Even shares that aren't registered as over diff, if they're not error shares, should clear the reset timer. We have sticks running at diff 512 that don't reset because they're submitting valid shares regardless of the pool vardiff. If a stick submitted no shares to cgminer (not the pool, cgminer), or submitted only error shares, for a period of ten seconds, it would reset. If everything's working properly (chip has good voltage, stays cool etc) that should be a very unlikely condition.
The stick is set to 150 mhz, my guess it's the voltage. (I had to crank it up a bit) I have 0 HW as speak but it's only running since 1 hour. Maybe i'm too close from what my usb can handle in term of amp.
I restarted my cgminer with diff set to 8, no reset yet.
It would looks like this message

EDIT: the chip is cold, I have a use fan pointing at him.
EDIT: other then the reset ... it's looks all good, getting 8.29gh pool side (ck solo pool with our group)

I can attest to this. The RPI does not work with all hubs. Avoid 3.0 as there is a very good chance it just wont work. On 2.0 if the powered hub sends power feedback the PI does not like it.
I have seen one guaranteed way to stop power feedback some say cutting the red wire works (do not do this if usb cord is attached to hub only if it's a cheap usb cord not connected). I did this on one and it did work.
Other weird way I found to make some powered USB hubs work with pi is put a non-powered hub between the powered hub and the PI. I tried this and it also worked on the hub I had.
Or you can read a few boards do share one confirmed to work with PI but i prefer to tinker so I bought cheap good powered ones and tinkered with them.

Never had to adjust the difficulty in cgminer-gekko and those difficulties seem way too low.
I'm steadily running @300mhz 7.2 v adj. @ 1.52a with 4 hashing about 16-17ghs. They do get warm about 50c with a quiet 120mm fan on them. No hardware errors in 3 days though and about 7 w per stick.

Quick question, My compact reset overtime (10 sec without hashing detected).
During the night it reseted 4 times, I use a diff of 16.
I will lower it to 8.

What is the question?
Also which miner software is that? I never noticed the gekko cgminer do that.
A Diff of 8 on the stock stick setting should give you 2.something shares per 10 seconds.

My understanding is that neither the "21 Inc Bitcoin Computer" nor the "Antminer R1" are released and shipping yet. While the prevailing sentiment is that they will both largely be "closed" in terms of configuration, how does anybody KNOW this?
It seems until we get actual documents, and/or a shipping product, it's kinda speculative as to what can and can't be done. I don't have a specific interest in either product, but it seems a bit premature to decide what they can and can't do at this time.

Do not know why you think we are speculating on the R1? This from the Bitmain Website.

The AntRouter R1 is a wireless networking device containing a bitcoin mining chip. The R1 is preconfigured to mine on AntPool’s solo mode, meaning that as long as the device is powered, you are competing for a chance to solve a block and win about the entire block reward of 25 bitcoins(after deducting the 1% fee).
Shipping starts from Oct. 8 after receiving full payment.

From the Bitcoin site with their short listing up for that 10 unit test sale... from memory it was 5.5gh, the price seemed like a placehold but it was 0.02BTC. I'm not sure what the real price is? And the aforementioned detail that i posted earlier are from Q&A with Bitmain's CEO.

If someone wants to test that functionality, groovy. I won't, because I don't feel like buying an AntRouter, for the same reason I wouldn't buy a 21e6 dangle that points everything automatically at a single pool with no option to reconfigure.

Even if it is closed I forsee people getting around R1's limitations. Look at phone rooting/jailbreaking. And I think it will not be horribly hard to modify their router since in past their miners allowed 3rd party firmware. (For example smit's firmware). So likely a firmware will do it.
So I don't know who but i forsee someone changing some features to more like we would want them.

I don't think anyone's successfully pushed a Compac to 500MHz yet, but we've gotten decent results above 425 with very top end voltage (one of Novak's small flock of stress test subjects got about 815mV). I think the only way to go higher would be to reduce the top divider resistor, which allows the pot's sweep a greater range. This is the small blank resistor near the pot, which is nominally about 35K; reducing it to 30K takes your pot range from 550-800mV to 615-875mV which should be much higher than you need.

It is a downer it does not allow you to pick pool. I personally want to be able to send it over to the compac solo club phil has over i pools. I do hope you can find a way to mod the R1 to allow pool choice.
The R1 shipping is also crazy. To US it costs over half of the device cost I believe. Which is an insane ratio.
Looks like RPI will remain king for compacs as far as little controllers.
