What did you do to bring up voltage or were you changing resistors?
"Pencil mod". I'm at work and can't remember the value though. I do remember that it only took a *very* slight change in resistance to get the same voltage of my other cards. If you tell me the value of your R02F resistor, I can tell you what resistance to shoot for.i want to say that i moddd from 31->40GH by changing the resistance from ~1.7K to ~1.570K or something similar.
however, it can take a few hours for the resitor to heat up and bring down resistance=rising voltage=further heat, and when errors start kicking in or hashrate drops, just touch it with your finger and a miniscule amount of lead will come away, hopefully raising 0.010-0.030K(ohm) per touch. ive almost found it easier to tune backwards like this, since adding lead is a bit harder to fine-tune (+0.020 to -0.050K each time i attempt to add a miniscule amount of graphite)
go to an art store and get a 2B or softer pencil. 2HB lead is hard to work with, and using a 4B pencil is much easier

I luck me I got good PSU self shut off the power. I dont know what to do now.
ps: warning anyone got hboards and check for bad solder on asic chips.

How far along is shipping for October deliveries? Is there a thread here tracking them? What order number are they up to?
Order ID: #3XX Status: BTC Paid
No shipping email for me so far...
Same on my 2xx order
October 21, 2013, 01:47:58 PM
PS: these Hboards gave me shit when hhoards hashing about 10 to 20 minutes all of them gone to 000 hash.
I had the same thing happen with my new v1 h-boards until I brought the voltage up slightly. I noticed that on 4 of my 6 h-boards, different resistor values were used. October 21, 2013, 01:43:27 PM

My order 64x Ready To Ship last Friday and maybe might ship out today or this week.
I just got my miner from Fedx guy.

I believe there are 2 order queues: one for old H-boards and another for everything else. The old H-boards queue has started moving last week but has not yet reached mine (#8xx).

Yes, you need to make it. you can make it inside /opt/bitfury/chainminer directory

Update for v1 M board owners. If you want to use the latest build of chainminer with your version 1 M-board please do the following
a) Download chainminer master on your raspberry PI from github and unzip it
https://github.com/bfsb/chainminer/archive/master.zip
b) change line 6 in miner.h
c) make
d) move /opt/bitfury/chainminer
e) copy chainminer-master directory to /opt/bitfury/chainminer
f) mine with latest chainminer goodness 
a) Download chainminer master on your raspberry PI from github and unzip it
Code:
https://github.com/bfsb/chainminer/archive/master.zip
b) change line 6 in miner.h
Code:
1 #ifndef MINER_H
2 #define MINER_H
3 #include "handylib.h"
4
5 #define NDEBUG
6 #define VERSION 1
Code:
cd chainminer-master
make
cd ..
Code:
mv /opt/bitfury/chainminer /opt/bitfury/chainminer_v1_original
e) copy chainminer-master directory to /opt/bitfury/chainminer
Code:
cp -r chainminer-master /opt/bitfury/chainminer
What is the update getting you? Better stability? Better performance?
In my experience (v2 board - v1 should be similar), the chainminer update improved stability such that error rates went from 3-10% per chip (5-7% average, consisting mostly of HW, but a few miso or spi) to 0-3% per chip (1-2% average, virtually no spi/miso errors). this also allows a bit more room to overclock for better hashrate, on top of the 2-3GH reclaimed from removal of errors per card)
Thanks, giving it a shot on my 3 miners right now.
Didn't make absolutely any difference on hashing rate on my end after updating chainminer (other than actually dropping a bit my hashrate/noncerate). Perhaps a few less miso errors but it might be just cosmic ray randomness. Will try to further overclock them to see if they are less prone to shutingdown/throwing errors.

yes, browse its ip-address
October 20, 2013, 04:11:52 PM
Is there a web browser on the pi?

bank see to scanner faster now.
ps: I am back to old one now and hashrate bad for me.
