Topic: groepsaankoop TechnoBit K1/K16 - [STATUS] De meeste pakketten zijn onderweg! - page 33. (Read 54846 times)

During tests of single Avalon chip last night We were able to run it without misses up to 395 MHz.
We tried up to 450 but after 395 it starts missing data.
This without proper cooling.

niet veel nieuws betreffende de miners.
Heb wel zojuist mn punten gehad, op alles geslaagd
Ik ga morgen werk maken van de bestellijst.

Betaling via bitpay kan ik zelf niet organiseren, eventueel dus via iemand anders zijn account, als die dat ziet zitten (zie hierboven)
Dat is zowat de conclusie... (spijtig genoeg)

De betaling via BTC is enkel mogelijk als je bereid bent 10-20% meer te betalen, het verschil wordt dan verrekend in de verzendkosten. Uiteindelijk zullen deze verzendkosten dan toch via overschrijving/cash geregeld moeten worden...

Interessant, loop je dan ook het risico je punten eventueel te verlagen als de tweede poging slechter was?

Hartelijk gefeliciteerd!

Nog plannen om herkansingen te gaan maken zodat je je profielpunt kan verbeteren of zeg je ik vindt het goed genoeg zo?

Todays Update.

I spent all day testing and trying to find what is causing HW errors.
I also did some comparison/companion testing with the Erupter that a very generous turtle83 sent me. The Klondike and Erupter ran fine together, and the cgminer menu items seem to be fine now too, after updating to 3.3.1.

I spent a lot of time analysing share.logs and running the data through my kslog util to generate work data for ktest. What I found out was that almost all the HW errors are non-repeatable. If I take accepted data and feed it back in manually I get the same nonce out. When I feed similar data that resulted in error nonces I usually get NO nonce out at all. This seems to indicate some problem with midstate/precalc/data not getting into the ASIC correctly rather than errors caused by bad result capture. Now I checked my code several times trying to find anywhere the data gets corrupted before pushing to the ASIC and can't see it.

As the day progressed I found the error rate dropping off as well. After a run of 1.5 hours along with the Erupter I found that the Klondike had a bout a 3% error rate, and the Erupter about 1.5%. But I'd been getting a lot of Rejected shares and I wondered if that was due to the slow speed and delays in submitted shares or what. So this evening I switched from 50btc (getwork) to BTCGuild (stratum) and saw that Rejects dropped a lot, and so far HW Errors are completely gone to 0 (knock on wood).

So it could even be that some problem with generating work with GetWork is sending bad data to the Klondike (?? weird), as with stratum (local block generation) I have not been getting HW errors. I'm trying to understand how that can be. Never see USB disconnects at all now. And if HW errors drop right off with stratum, then I'll probably add another ASIC and start checking the chaining next. Right, now running at 150 MHz clock, no heat sink and it's a bit hottish, but touchable with fingers for about 5 seconds.

Or maybe error rates actually get lower as the clock rate rises because going from 128 to 150 seems to have lowered the HW errors. Hmmm. Figure that out.

Plan for tomorrow: solder down more chips.

Hartelijk gefeliciteerd!

Ben je nu ook geslaagd of moet je nog verder studeren?

Jammer dat er niet meer bekend is van de mijners maar goed, dat komt nog wel. We moeten sowieso nog even geduld hebben.

Ik heb een bitpay account voor mijn webwinkels. We kunnen altijd die gebruiken.

Nog niet zo makkelijk zonder KvK https://bitpay.com/terms

BitPay lijkt precies te doen wat je wil. Het is volgens hun site te gebruiken voor donaties, independent contractors, webwinkels, etc. Het zou toch niet uit moeten maken of je een officiële 'merchant' bent of een groepsactie organiseert? Er is alleen de vaste fee van 1% en geen maandelijkse- of opstartkosten. Ik zou zeggen, gewoon een zelf bedachte bedrijfsnaam invullen.
