Changing Voltage A1's question

[emdje]

Hi guys and girls,

I am working on the software for the A2's, which are almost identical to the A1's. I have read in this topic: https://bitcointalk.org/index.php?topic=294235.0 that there are people who adjust the voltages of the A1 chips. I was wondering how that works? The programmers guide is hinting that it is possible to do that by software, but does not state how. Does anyone of you know who that was done in the A1 chips??

Thnx in advance

Hi

I know how change voltage with replace smd resistor
for sample replace 09C instead of 05C
this about 0.88v

Thank you for charing
Is this a photo of the A1 board? The voltage regulating part looks identical to the A2 (which would be awesome )

The voltage now is .88V? And it use to be .84V?

Yeah, now voltage is .88v
for .84v return factory resistor 05C

I try with resistor 03C voltage about 0.828v

That is very nice 
Do you get less HW-errors using higher clock frequencies with the increased voltage?
