If you have a new miner without a lot of HW errors (cores turning off) you may be fine with .95 but just know you are stuck with a substandard miner compared to one with 8 VRMs

Why isn't a 4 VRM board just as good as a 8 VRM in terms of hashrate?

I gotta call BS on that. I have  4VRM boards on my saturn that can do over 300Gh/s with the right firmware. .095 slowed it down
your 4vrm board is like that because there is a bad vrm, like you stated...  it has nothing to do with the amount, except if the other 4 were there, it would have had redundancy
I appreciate the firmware info, and am thinking of reverting to an earlier firmware also
which do you feel is best?

which software for 300gh?

[Puppet]

So, you used guestimates of people who counted order numbers and came up with over 2 MILLION Chips from BFL?!

1.2M. And FYI, that amounts to a little over 1000 wafers (http://www.silicon-edge.co.uk/j/index.php?option=com_content&view=article&id=68), or ~$2M which coincidentally is around the amount you would need to be able to order directly at globalfoundries without having to go through intermediaries.  GF has several 100,000 wafer per month capacity, 1000 per year is not exactly a big deal for them.
BFL recently said they could now order directly at GF.  SO yeah, that sounds entirely believable to me, and it also rhymes with claims made by BFL earlier about their % of the installed asic base when you contrast that with their order queue.

Of course you are free to dismiss all those estimates, call me an idiot and actually believe published orders on this forum are more accurate. If so, you would also believe that KnC only sold 158 Jupiters:

Not the ~1500 most people assume.

0.94 & 0.93 both worked fine for me

1,2M was before the update, that update was 22 April, since then with his calcutlations and added +2M Gigahash it's at more than 2M. Read the sources you quote right.
Recently said? They have those orders standing since about half a year according to your source!
Stating anything that BFL says as believable puts you in a new level of troll.
Also, I did NOT state that my previous comment is valid for KNC Orders. They had not more than a year in wait time and therefore not all orders can be accounted for. Also, they do not have that many orders stated on their own forum AND they are way more public with the upcoming independent movie and their general publicity is way better. Don't compare stuff that can't be compared.

can someone explain exactly what the "hard reset" does...   does the firmware stay, or revert to...?

if anyone is interested in a detailed account of dealing with 4 VRM boards pre-.95 I posted it here:

https://bitcointalk.org/index.php?topic=306969.msg3325981#msg3325981

For anyone that has been running overclocked 4 VRM boards (since that was the only firmware we had to choose from) then you might want to really think before switching to .95

If you have a new miner without a lot of HW errors (cores turning off) you may be fine with .95 but just know you are stuck with a substandard miner compared to one with 8 VRMs

Based on reports from users with Bertmod, 4 of the 8 VRM's were NEVER supplying power.

It IS possible they had some benifit but it was not to supply power.

If they did by some wierd fluke add some benifit, that could be added back using less expensive components.

We now return you to your regularly scheduled tangent.

Whatever. You try ordering 500 wafers directly at GF, let me know how it works out. FYI  GF has 3-400,000 wafer per month capacity, for less than 100 wafers per month they dont even pick up the phone and you need to go through intermediaries.

1) There are no more refunds.

Not necessarily:

Refunds are offered up to the day of shipment of your order.

Blown capacitors - 4 VRM, 8 VRM, don't know?

[Phoenix1969]

ok, I have a serious problem....
aftre starting CGminer, I ssh'd in on another window, and discovered that there is another instance of cgminer running, the one with all the wrong info...
when I try to "Q"uit that instance, it ignores me
when i try to get "S"ettings it ignores me...etc
i have to start a second instance of cgminer for the miner to start
the pool info page changes the second instance, not the first, so when i restart, all the wrong info is back
apparantly it's been like this all along...
what to do?

[DPoS]

I have wrote in length in the other thread since this one turns to mud quickly


hard reset brings a lot of factory configs back. (if you dig around you will see files with .factory on them)
also, I found the only way to get the 4 VRM boards to overclock again is to do the hard reset, upgrade to pre.95 firmware and then shutdown and start up.  To do that I always quit cgminer, shutdown -h now, then pull the pin adapter plug out then turn off switch on power supply.

Well, you could ssh into the Saturn, #ps aux | grep cgminer

Then, identifying the instances of cgminer that are running, jot down process numbers

Then #kill -9 12345 (the 12345 replaced with the process number of an instance of cgminer)

Then do the same for any additional instances of cgminer running

Then restart cgminer adn it should be the only instance running.

overclocking?.... how are you doing that?

4 VRM boards with pre-.95 firmware FORCED us to overclock by running high voltage/amps from our VRMs.  The reason I was able to get to 520Gh stable on my miner with .93 was that the overclocking compensated for the HW errors and that .93 restarts often if you miner starts to drop performance.

You can notice overclocking by the WU value you have compared to the number of cores you have running.  When you run .95 on a 4 VRM miner you will see a big decrease in WU

Since I am stuck with running .94 I will try putting a cgminer restart in the cron for every 30mins or hour to keep performance up

You could try and kill the service.

Do a ps - ef | grep cgminer

Find the pid number. And do a.  kill -9 pid number

this thread is full of people who write first and read maybe


if you have been paying attention, boards with 8 VRMs and pre-.95 regulated all the VRMs to the low .70's range while the 4 VRM boards flew up to 80's and 90's

I have a miner that has one board with 8 VRMs and the rest 4 VRMs.  Here is a screen shot of it running .93 and it has been stable hashing ~520Gh rated at pool for days

[Phoenix1969]

ok, i can get 1 instance going... and i have added the bogus workername knc cut& pasted into the worker name field to the pool, so that should work....  BUT...  they added HTTP://  to the stratum address!!!!!  and i cant seem to get the settings to save to change it


So, my next question is.... what filename are they using for the config file, because its obviously not the default?

[jelin1984]

how do hard reset
because i do like the manual

and i can not know if i done or not(hard reset i mean)

again for quick typers and slow readers, this miner didn't have a crap VRM until I switched it to .95.  It did have a lot of HW errors which the overclocking and the watchful cgminer restarts of .93 kept it producing ~520

Fact is that they should of tested the 4 VRMs and made adjustments before making the switch.
