We have been running with 750k limit since around March.


Hi fireduck,

I've just controlled all listed found blocks, this is the biggest one  at 270KB, a lot of them are at 25-100 KB.

Am I missing something?

The block size is a deliberately limited resource.  It's not up to Fireduck to change the Bitcoin blocksize.

Redacted,

in bitcoin.conf you can increase it up to 1 MB right now, I don't know how big it is right now, but from mined blocks I'd say it is at the default value of 250 KB.

If fireduck has enough CPU power at his disposal increasing it could give a nice return to miners here.

Is that really possible???

Hi ngzhang,

can you share with us some news/facts about the new 55um chip?

Are you going to build replacement blades for existing Avalon B1/B2/B3 units to "upgrade" them to the new technology?

Thanks!

4 blocks in two days, not bad Smiley

Anyway, fireduck, do you think you can increase block size? To increase the "lottery" reward for those that find a block.

Hey Punin,

I received my order today.

I noticed that four of the hboards in the full kit still had the caps on which you said you were removing. These boards were marked for slot 4 in each bank.
In the other full kit, none of the boards had the caps.

Is this intended?

Yes, those are EOL boards, see https://bitcointalk.org/index.php?topic=287590.msg3392564#msg3392564 and https://bitcointalk.org/index.php?topic=287590.msg3390730#msg3390730

My Raspberry PI got shorted out, a diode on the backside burnt out. I had upgraded from v1 Mboard over to v2.3 Mboard. It lasted just 5 minutes or so before burning out. (I had oriented it correctly, HDMI port facing upwards, etc etc. It  mined for a few mins as well ). Now back to v1 Mboard. I think the PI does not like being fed power through the pins, and rather expects a micro-usb plug.

I had read sometime back that people complained of red-hot smoking rPI after plugging it in on the new Mboard. Anyone else concur?

I was wondering, mind you out of nothing, I'm not an electronic engineer, do you have fans attached to your mboard?

Can fans attached to the mboard help preventing this "absorbing" such a spike?

Just got an Avalon Mini.

2 cards running at 375Mhz.

Its supposed to do 60GH but I am only getting 49 to 50GH.

The other ones I have do 60.

Any suggestions on how to fix it?

some chips wont work and stay at 0

same problem for 2 mini avalon and i have 2 other box not open

I see the same in mine 17 to 24 are 0 which leads me to believe they don't work. Someone told me that these mini's only have 16 chips in them, which would make sense. 2 modules = 16, 3 modules = 24, and 4 modules = 32. So I am still not sure if I should reduce the 24 miner count to 16.

My mini gets 59008.84 MH/s which isn't the full 60GH/s but I am not complaining! Smiley



Inside /etc/config/cgminer you have an option named "miner_count" which I think is at 24 right now, try to change it to 16, it should fix your issue.

Mind you, I have not tested this change and I don't have a mini.

Uhm,

I'd say en error in cgminer options, a two modules unit should have 16 mining units, while a three modules one has 24 of them.

I'd like to show an example, mostly to our new fellows, of how block's fees reduce pool's fee that each miner pays to the pool.

This is latest found block: https://blockchain.info/block-index/429263/00000000000000072089a0adae2b921c93f3d707c1180b7dae1b63ef03e0dd78

It paid a good 0.15 BTC to the miner who found it.

Sorry for nitpicking, but selling chips is more profitable than mining.  AsicMiner is case in point, with business model involving sales of demonstrably unprofitable gear.  

But this business model is dead now...

See my sig for the best business model right now Wink

Sure! losing 10% to 20% a day since monday and more than 50% since it started, per each GH/s you own, is the right business model... to go bankrupt. Wink

ghash.io now at 630TH. Id love to know how much of them is their own hardware, and how much from miners just using their pool. Anyone have a clue?

No clue, but I'd say 400 TH/s are made up of BitFury's own hardware, the rest miners, since BF reached at least 250 TH on its own last month, before starting Cex.Io.

August production cards ... with caps ...
October production cards ... without caps ....

but ...

august delivery ... with caps ....
october delivery .... without & with caps .... I got 1 out of 14 that had caps

a lot of cards have a signature like A1 ... or B4 ... B2 ... A3  ... it looks like they where
already used in a miner slot before ... so probably october delivery ... is build up out
of miner breakups ...

I'm unsure ... if that is the truth ... it's just a assumption ...

The biggest problem, it seems to me, is that these h-boards are produced with substandard quality, are noisy and picky, caps burned out so they were removed instead of being replaced with working ones, some chips cannot be seen if you don't disable one of them, errors spring out of nowhere in a working system and then disappear if you restart your system, h-boards connectors on m-board are too flaky.

I mean, august kits, ok, they were in a hurry, but on october kits, I'm disappointed by the fact that they still shipped EOL boards and that even new boards show all the problems of the old ones, so it means there was no improvement in hardware and software.

When you consider the 18K EUR price tag for the august kit and 9K EUR for the october one, this level of problems is barely acceptable.

Has anyone noticed that the version 1.2 h-boards with and without capacitors don't mix well?  


Same here,

my october kit is made up of 12 new boards and four old end of line boards, each EOL board is the last of each bus, so A4,B4,C4,D4.

Everything was working at around 460 GH/s out of the box, but yesterday I decided to do a little pencil mod to the EOLs boards... hell broke loose!

I got tons of miso errors both on new and EOL boards, in the end I had to remove board B4, which, for unknown reasons was causing miso errors on all the cards in bus B and, from time to time, even to the other buses.

I'm using a 1000W single rail PSU, so it should not be a power issue.

I'd also like to know what is the max amperage that the  m-board can deliver but overall these kits remain extremely picky and instable systems which can stop working even for very small changes.

Here is my system now, as you can see I still have miso errors here and there, but they don't seem to affect hashing too much. Boards 3,B and F are EOL boards with caps, slightly pencil-modded to 1.20-1.22 on RF02.

Is it true you'll get more or better payouts with a pool that has more people in it? I'm guessing the more users in a pool the quicker they solve a block, hence more payouts. Is that thinking correct?
Thanks.




Partly, you'll get more payout but each one will be smaller.

A bigger pool reduces your variance, not what you're going to earn.
