[GUIDE] BitFury Miner Support/Tuning

This is achieved by penciling the recistances to about 1.1k, adding heatsinks and fans. Im still struggling to keep it cool enough during the daytime.
Once I get the cooling figured out I will once again proceed to optimising the error rates.

What effects are you seeing when the cooling is insufficient?  I have one board that autotunes itself to 0 and back to 30GH/s all day.  I am wondering if my cooling fan is not enough.

I am was seeing a single chip dissapearing, always the same chip and signifigantly lowered hashrate which could most likeley be accounted by the regulator overheating.
Atm it looks like I have cracked 70Gh/s for good with two boards and I might see additional imrovement once my Arctic cooling F14 fans get here (just ordered). They seem more suitable to cool entire h-boards than the slightly too small F12's that i am currently running.

Anyone getting over 500GH/s with a full rig?

If I had a full kit, I would be past that with a healthy 10% margin:

Once I get the cooling figured out I will once again proceed to optimising the error rates.

To keep this cool, the simpest method is using pump, radiator , tank and cooking oil to maintain the working environment as the system is not so complex, which will be broken if the forked coin cannot be mined efficient.

I wonder how my router would react to the oil leaking trough the network cable.. and how the pencil mod would work under it. But I would love to see someone do and report on this method.

[juhakall]

I have two cards doing 66 GH/s.  I cool them with a 6" AC fan, 0.35A@110V, 200+cfm.  Works very well.  The 12V fans were not able to cool the cards.
For the full kit, my plan is to have 3 AC fans, blowing 600 cfm at them.  Probably an overkill, but the cards will stay cool.  No heat sinks.

How did you mod the cards? 66GH/s without heatsinks sounds great, I'm currently just at 60GH/s after pencil modding R02F resistors to 1.18k.

[btc4life]

I am currently getting 551GH/s noncerate as a type this on my full rig.   Running R02F at 1.2k, small heatsinks attached to the back of each board, 6x 120mm fans split on each side of the rig, 2x 200mm fans on the top of the rig.

The chip temps all seem to be in the low 50 C range or lower.

Good to know that 16 overclocked board can function well together. Thanks

nice ... can you link or tell what you have done ... on the backside of the regulator ... how much space is there ... if all board slots are filled ...

I have only put these small heatsinks on the board ( http://www.amazon.de/gp/product/B004BU6ITM )
-Cooling the Boards with 120mm fans
-Pencil mod to 1,1kQhm
-modified the config to speed 54 / 55

there is almost zero space left from the heatsink to the next regulator... but it fits

very nice! How many small heatsinks are in this paket? 12? Are these the same? They are cheaper http://www.amazon.de/gp/product/B004BU6ITM/ref=ox_sc_act_image_1?ie=UTF8&psc=1&smid=ALPJ49DNEL3HT#productDescription

[puffmais]

Yes, i have bought these for 1,85euro
correct 12 small heatsinks and the other bigger ones are in one package.

[Foofighter]

I offer also heatsinks, if anyone needs - (3M pads already on the sinks)

Seems like I'm getting the best results with clockspeed btw. 54 - 55 ...

At the moment im letting the monitor script run for 2 hours .. then clock down
each chip that has more then 2.5% errors ... for most of the chip its 54-55

Inside miner's code there is this comment

Code:

//maximum chip speed available for auto tuner
//speed/nrate/hrate/watt
//   53/   97/  100/  84
//   54/   98/  107/  88
//   55/  101/  115/  93
//   56/   99/  125/  99

So yes, 55 is speed with max noncerate.

Hey guys

I have two EOL boards, 1 is currently plugged in at the end of the chain, I was wondering if I can put in the other EOL board thats not being used after the other EOL thats plugged in?


Thanks in advanced for your help..

If you have a v1 M-board, you can only use 1 EOL H-board. If you have a v2 M-board, you can use as many as 4 EOL H-boards, but still at the end of the chains.

Does anyone have input on my underperforming board?  It looks like there are a lot of MISO errors but I don't know which chip is producing them or how to disable the chip.
