Some beer money sent.

Everyone should send a few dollars to this man.

Hang on did you buy a KNC miner? It was priced in US Dollars, not BTC. If you paid in BTC you paid for the dollar value of the BTC at the time of purchase. If you decide to invest your dollars in something that generates BTC you can decide whether that generated income is valuable to you in BTC or in the dollar value of that BTC.

Thats why if you asked for a refund you wouldn't get the refund in the same amount of BTC you converted to pay for it, you would get the refund in the current number of BTC that equals the amount you paid for the device.

I'm investing my cash (because I paid cash, not BTC or BTC converted into cash) in a machine that will create more cash than I invested. I only care about the BTC part of it from a) a conversion medium for cash, and b) a technical whimsy*

*I like technical stuff, in fact I have more money invested in Protein folding research machines than I do in bitcoin machines, and they have zero ROI

I only care about the BTC generated by my miner in as much as its value relative to the fiat I can convert it into eventually.

Of course its about the $ value

How would you feel about ROI on miner hardware if the reverse was true?

If you had paid 100 BTC for a miner when BTC was worth $100

You mined 101 BTC but BTC value dropped to $50

Would you say you have made a ROI? I'd say not.

Some people don't find trading BTC a satisfying vocation or even pasttime. Some people like to mine.

As far as hobbies go if my Jupiter makes as much as it cost me in $ and then some then I am happy enough and fuck what the wife thinks, at least I'm not pissing it away in the pub

People should have more respect for miners, for without them ROI or not there would be no BTC in the first place for people to trade. Let us have our fun without rubbing our noses in it.

I and many others didn't pay in BTC we paid in $ in which case its a moot point.

The price for the machines is in $ its always been in $ it doesn't matter what currency you convert to create your $ its still $ in the end.

Running 3.7.2 with 0.96 firmware no problem

please understand I could be wrong, I'm not working or programing for KNC so it's partly guesswork on my part.

The version is probably just a variable stored in the Web code.

Think about it if the link you get after upgrading the firmware isn't run, the way these rigs are setup is to reset alt of stuff on reboot. So the firmware update code that needs to be run against the system doesn't get run because you are using a different reboot method that doesn't run the commands before rebooting.

However the bits of the update that don't require a reboot are copied over such as cgminer etc si they work fine.

Your symptoms of worse performance when rebooting using the link are similar to mine. Always worse performance. So I kept going back to 0.96.

But now im using the old firmware but the new cgminer and I am not getting the performance loss.

So there must be a lot more being changed when you change the firmware than just updating the cgminer instance, and alot of those changes will be related to what happens when you click on the reboot link after you update the firmware.

From what I know of them, unless they have a component shortage they will be using this time to build the November batch. I expect they want to minimise the issues they had in the first run.

Afaik you will get your miner in Nov but the latter you order it the later you get it.

As for ROI its unlikely, but not impossible.  It depends alot on how much hardware KNC releases before the end of the year +  bitfury + BFL. Everyone else with 400Ghs+ products seems to be delayed till Dec/Jan

Awesome, thanks!

I'm trying sticking with 0.96 with the latest cgminer binary and it seems to be going ok!

What bus were fixed btw?

So after you upload and apply the firmware, it returns to a screen that says restart miner, is that the link you clicked or did you go back to the home screen, then go the the "Mining" and click on "Restart CGMiner" on that page?

Exactly, so effectively as you are not running the proper reboot command it might not be updating the firmware, probably a good thing in your case, you are just getting the updated miner.

Hmm.. I think I might try it

Yes I would have thought if you don't reboot after the firmware upgrade then the firmware isn't actually installed, yes maybe cgminer gets updated but nothing else.

I take it I don't need to run enablecores if I don't have any cores disabled (in bertmod)?

The only time I had to run enablecores was when I upgraded to 0.98 and cgminer kept turning cores on and off all the time until I dropped down to 450GH/s

The reason why I went back to 0.96 is that a) it gave me 555+Gh/s steady again and b) my cores stay enabled all the time.

Dunno if maybe the higher voltage of the later firmwares cause problems with my Jupiter or if its that cgminer is too eager to disable stuff.

Whenever I run bertmod on my Jupiter it shows all cores enabled and steady voltage and watts across all VRM's

I'll try 0.98.1, I always try the latest

0.96

I wonder if those that had an easier transport had less hardware issues? I picked mine up in Sweden and flew home with it, and yes although it did go in the hold and suffer the horrors of Norway Air baggage handling and had all 4 fans fall off, it may have had less of a traumatic journey than via UPS/DHL van. Because mine has been happy on .96 hashing at 555Gh/s with zero bad cores according to:

You can create separate workers on the same account with BTC Guild or many of the big pools. Just click on Workers once you are logged in.

You need a klaxon and rotating orange light every time you get a payout.

I'm "getting there" got mine (sic) on the 16th Oct

Can I hate you now? :p

I think people are still interested and appreciate the work you do.
