[GUIDE] BitFury Miner Support/Tuning

[klondike_bar]

how is that handling compared to the individual VGA heatsinks you were using? any increase in overclocking headroom, or is 38-40GH still the practical maximum?

Copper server-grade heatsink for Bitfury H-cards. (wish I had found these sooner, now that 55nm is on its way out)

Do you put an 'X' of thermal paste on the back of heatsink, with glue at the four corners? I'd like to do this, but I'm finding conflicting advice online on how much paste to use, and how to apply it.

Goxed -
What do you use for thermal paste and glue?  I would like to try this but I have never used either.
Recommend a supplier?  I am sure a bunch of places carry it, but curious.

it does not help a lot with speed esp. if the card is running at 35GH/s+, but it will pull up a 30GH/s  card with a few overheated chips. Increases reliability and hopefully longevity.

I have a link to the ebay supplier in my posting. each heatsink comes with 2cc thermal paste . You can try arctic silver or antec diamond if you need more. I used superglue as the adhesive between thermal paste

A small dab behind each chip, and superglue in between.

[Trongersoll]

I should probably be able to figure this out, but i'm no where near my rig. did you put the heat sink on the chip side of the card or the back side? Also, I'm just running my rig stock, no manual tuning or over clocking, with a couple of fans blowing on the boards. Would i see an increase in hash rate just by adding the extra cooling the heat sinks provide?

hey guys i am running in to a problem with my rigs. i have two full rigs (v2 h-card & v3 m-board)
for some reason both of them just stop hashing. what could the problem? i'm still able to go in to the web browser.

Hit save stratum info, wait for the confirmation.
hit stop miners, wait for the confirmation.
hit start miners, wait for the confirmation.

It should be hashing again in a minute or two, if not something else is wrong. (Internet connection working?)

its not working. i really don't know whats wrong it was working fine. internet is working correctly. i have other miners that are still running.
its still looks like it is hashing from the blinking green light. but on the site (bitfury admin page) it shows 0 hash.

[daddyfatsax]

Please forgive my ignorance on this, but can I put bfgminer or cgminer on the pi and use that instead of chainminer? From the bfgminer page, there is no support for the V3 M-board and I have not been able to get cgminer running. I can compile it with bitfury enabled, but when I start it up I get nothing.

sounds like the pool info is correct or recently changed. check its configured correctly and connected to internet, not just the home network

i'm successfully running salfter's image of bfgminer from here:

https://bitcointalk.org/index.php?topic=251966.msg4511347#msg4511347

just installed it yesterday and the great news is it seems to have solved my "reset" problems i described earlier.  that was my first priority in evaluating bfgminer.  i still need to fine tune them as the hashing rate is not optimal with a fair # of HW errors on some rigs but i'm very much encouraged.

Awesome. I wasn't sure about that one, but I will give it a try. Thanks for the help.

make sure you change the pool settings as they currently are pointed at his pool

make sure you wait at least a few min for hashing to occur.  make sure you have enough cooling via fans +/- heatsinks.  try rearranging some h boards.  other than that, rebooting should've worked.

Thank you for taking the time to reply.

Couple things to add - Ive had this up and running since December. Ive had the speeds up to 55 (880) but AC kept turning off, so I lowered down to 52 until I got that fixed. The AC was fixed today so I bumped the speeds up to 55 again and proceeded with the reboot.

Logically followed it would imply that I screwed up the best.cnf file or something. This happened once before where I had did a search and replace all of 55 to 52, but forgot to go back and change the chip numbers 55, 155 and 255. Once I fixed this the miner started up fine. Knowing I had done this once before I manually checked all the chip numbers and they are sequentially correct.

Is there any way to make/restore a default best.cnf?
