you are right, the back side is prefered but from temp measurements there isnt so much difference between both sides in temp.

I ordered new heatsinks because many people asked for it, should have them in hand in 1-2 weeks.

So Iam open for new orders here.

cheers

I have offered small heatsinks here a few weeks ago- but have none left-
If there is interest I could order some more ? I offered them for about 0,1btc per 16 small sinks excluding shipping (shipping was about ~0,05)

But as this is not really a profit based thing, I would only order again if there is interest from enough people on GB basis.

Good News

BG1 refund was finally received.

I am sending the list for GB1 refunds to John K now for him to start asap refunding the buyers.

As I mentioned before we will not be held responsible for wrong btc addresses in the list, etc.



good news bizwoo! great.

There is no problem with the cable itself, but somehow the connection of the cable doesnt work Sad

Havent found out why, maybe someone who got his already has a solution?

definatly too high if another card is behind the card with the sink.. in a full setup I would suggest heatsinks with an height of 10-max15mm

Two quick questions on the goxxed info.  1) What points are you using exactly to measure the altered voltage?   I am leery to probe around the board while powered up for fear of shorting something.
                                                        2) What exactly is reniceing and why is it important to reduce?  This is the first time I have seen this term used in the bitfury threads.

Thanks very much and awesome work!  Grin

Meanwhile I have a stable nonce rate of average >35 Gh/s on both boards - so time to give something back:

You can measure the voltage on nearly every capacitor on the board, I usually use the bigger ones directly beside the DC/DC converter, left to the coil (the bigest part on the board). There are not many ways to do something wrong, just make sure to not shorten your probes, as there are 30+ Amps available. (I have exactly 0.840 Volts there with 55er clocks and it looks very stable, although there is no easy way to measure the real current draw on the core voltage and confirm that everything is inside bounds.)

BTW: I also reported about a mysterious chip, which usually throws lots of errors, but sometimes recovers completely after a longer uptime. When running this board alone or in switched order with the other one, the errors of this single chip also disappear.

Hi, thanks for sharing.

Can you also confirm the Ohm values given above?

Hey marto,

could you add 4pin connection cables to you shop for chaining miners?

cheers

Could you please answer that?

If I only got 1 drillbit board , Can I run it without a backplane?
