Might be a issue with my clock source setup. Used a 74f04 hex inverter IC to get the crystal oscillating. Might have the wrong capacitance on the crystal. but My block erupter likes to run with a 16 mhz crystal installed and a active mini fan cooling system

changed the voltage resistors to 1.2k
Hashing is all over the place between 390-500 mh/s Im wondering if this is my cgminer settings? sometimes the status led stays on for a bit of time as though it is waiting for work.

What is your error rate? From your post am I reading correctly you replace R1 and R2 with 1.2k resistors? That would be 1.6v correct? I have a 16mhz oscillator installed on the board and am trying tweak the voltage to get it stable.

Hi Bluestreak66 could you please point me in the right direction to order the correct 16mhz oscillator for the circuit? A link to a supplier site or part number would be really helpful.

Thanks!

This is the oscillator I currently have on the board http://www.digikey.com/product-detail/en/636L3C016M00000/CTX691CT-ND/604649 It doesn't seem stable over long periods of time and I get timeouts from the board not communicating after a while. I'm not sure whats causing this, cooling does not seem to be a problem. I think It may be an issue with the on board voltage regulator as I get core voltage fluctuations over time. I haven't had much time to mess with it.
