confirmed thanks

any issues with the kit or has it all been plain sailing ?

cheers again

Hi All, the normal weekly payout has just been sent. Details are below as usual.

sweet thanks for the payment

Thanks for the early payment. 

Hi All, given the crazy BTC prices at the moment we thought that it might be useful to send out an early payout this week (just in case you're thinking of selling while the price is high ). Please see below for the payment details. I'll still send a payment out this weekend as normal.

No problem. You may also find http://blockchain.info useful, if you weren't using it before. You can monitor your addresses, the miner's address, particular transactions etc. Very useful indeed.

sorry im still pretty new to the wallet and instead of generating a new address for these transactions i used the first one i found.

I have updated my mining pool with another address so i can now easily monitor income. Just have to remember that you didn't make any payments before 3 rd !

Perfect, I was getting worried there. Thank goodness the blockchain allows us to track these things easily. One of the great things about bitcoin IMO.

Hi monkeynutts, you were included in Sunday's payment TxID: e23dcb6b01bd118342d11aaf9d8adb93aaa5a3fe980766c3d6fcd4524125f630. BTC from the group's miner are being paid by the pool to 1568Cr5PQFy3JVhQnvajQkbYyinM4AcCFH, so payouts to you will come from this address.

When might i expect to see my first round of payments ? I'm right in saying all H-boards are now hashing away ?

thanks



Doh, I have used the same address for you and my pool miners, that's why i didn't see the payments !. Confirmed payment received many thanks.

I am selling 5 shares that I have in Component 5 (H-board #4) collection.

Please PM me if interested.

 

OK, I think it's time to close this component formally. I'll update the OP now.

Exciting stuff, thanks for the update Stinky_Pete. We're running the chips at > 3 GH/s in the bitburner fury, so providing there's sufficient voltage control in the drillbit firmware I'm cautiously optimistic that these boards will do 2.5 GH/s (hopefully more). We'll be adding a bit more cooling when this one arrives, so it will be like a hurricane inside that case! Hopefully that should suit them well.

Last call for shares in this component.

So if you want to buy some shares in this component, do it quickly

Hi All, time for a quick update. The miner has been running stable again this week . I've spent some time hand-tuning the "speed" of each chip on the BFSB hardware and this is now running at between 197 and 201 GH/s. It seems that it's possible to get about 5% extra out of the boards by manual tuning compared to using autotune. However, I think that this is pretty much as far as we can go without overvolting. Increasing the "speed" parameter, which presumably tweaks the chip clock frequency, any more than where we are at the moment just leads to a big increase in hardware errors. If the bitfury burner is anything to go by, it's important to increase the voltage available to each chip at higher clock frequencies in order to reduce hardware errors (the BFSB boards don't run in quite the same way though, so the comparison is not perfect). I put some heatsinks on one of the H-boards (see below) to see if this made any difference to the level of hardware errors when tuning, but unfortunately it made no difference. On the up side, this suggests that the current cooling setup is working well.

Others have shown that overvolting the H-boards (the so called "pencil mod", see https://bitcointalksearch.org/topic/m.3079421 for details) means that it's possible to push each board to around 37-40 GH/s. However, cooling becomes extremely important under these conditions and longevity/warranty may be affected. Let me know if you have any thoughts on whether or not we should have a go at this.

That will be fine, but I'd like to have everything cut-and-dried before the Drillbit boards are dispatched. The latest news is that they are being manufactured, but as with all pre-orders, there is no definite date yet.

Hi, sorry for the confusion. I need to update the OP - should have done this a few days ago, but I'm afraid that it's been a busy week . The collection for component 8 (the Drillbit boards) technically ran out of time on the 29th. However, there were some shares left and I think that it should be fine for some of these to go to new GB members (based on some contact that I've had recently with Stinky_Pete). Shares are always 0.5 BTC each and 25 shares will be issued for component 8 (this is based on the actual costs for the component).

Let me know if you're interested and we'll take this into account before finalising things for this component. Stinky_Pete will take the remaining unallocated shares if I understand him correctly.

hi

do you still have shares and how much?

Only asking as title says 11 shares left but in the post it says closed

This week's payment for all components.
