 I (still) have 4 cores on one die that are sitting in disabled mode - wish i could get them working.


not all cores are worth bringing back..  if they flap on and off all the time your HW errors fly up.  .96 seems to balance a lower WU but much lower HW errors for better avg.

would be nice to have release notes right??

I am guessing that it may 'give up' on some cores which is good for problem ones.   but would be nice to control that ourselves.  It would make sense that they have the enable_cores feature now to go along with this design instead of earlier firmware that always tried to bring everything back

Yeah - .96 is definitely working the best for me.  I didn't think it was at first, but that was 100% related to my internet being flaky (i ran the cable through a surge protector) and apparently that was introducing a lot of noise.

So I got my Mercury up and running with 0.95
It says its running via SSH at 144GH/s~
Slush pool is reporting 120GH/s~
40C~

Is it worth going to 0.96? Should I apply the enablecores patch? I dont quite understand its use...

And by the way, why would Slush report 20GH/s less than wha cgminer is reporting? My BFL using BFGminer reports exactly what Slush reports.

From what I can tell, the statistics that KnC's mod of cgminer is including the hw errors into the hash rate.  If you work the math backwards and include the A + R + HW values over set amounts of time, you get the long-term averages displayed.  Ditto the WU values.  I think it's been explained that the driver that KnC wrote is picking out the wrong values for cgminer to display and thus is theoretically fixable (though in the mean time it makes it look as though the miner is faster than it really is).

The most important number is the number displayed at your pool...that's the only number that you get paid for.

Yeah I figured as much. Thanks
I just didnt want to be missing some potential GH/s somewhere somehow with some black magic.

I'm not one for donations but if you must go ahead and I will keep you in mind. =)

I tried a wireless bridge... it sucked... totally.
Want one?...lol

There are some crappy ones out there for sure...but the one I linked is pretty awesome for those just now starting to wonder about how to put their miner on wireless and don't want to jump through a lot hoops to do it.
sure... all helps...
I was not satisfied at all with a bridge, it liked to drop connections randomly...
The laptop's range is like 10x as far, gets waaay better reception, and has never dropped the connection in 6 days so far...

The old WinXP laptop has a wireless that I disabled for testing this RPI router.  Since wasn't all too difficult I might try making it the wireless router instead of the RPI.  It does only have XP home so auto config is out but with the route command it should be possible.

Just off the treadmill and a couple of thoughts.  Must get DHCP working on the RPi assigning addresses to the .2.0 network so I don't have to add a static address to whatever is to the RJ45 connector.  But with the hot pepper USB connection, I can just plug it into the RPi and run cgminer on the RPi and it will be handled on the 1.0 network to wlan0.  I would need the RPi net .2.0 routing for the Merc tho as that would be to the RPi RJ45.

Simpler is to really draw the heat out of the BBB.  I have my first native BBB and haven't fired it up yet.  Different by far than Debian/Ubuntu/Rasperian linux, no apt-get to install programs.  Still I'm sure it comes native with whyfri pre-configured.  I have old racks of three fans that would plug into a CD drive opening, 12v, and as they're small, I think I'll put standoffs on the native BBB, add braces to fit the smaller 12v fan, and swap the native BBB for the Merc BBB.  The fan will be blowing down on the wrong side of the BBB pcb to best cool the warmest chip, but should work.  Then bringing out the USB on a cable, put in a USB wifi and wake up the Merc with the ASIC disconnected and no RJ45 ethernet connected and see if DHCP assigns an address to the BBB.

and here I thought I was getting paid per share...

Since a share = 2^32 hashes, the two are interchangeable.

SharePerUnitTime = HashesPerUnitTime/2^32, thus SharePerUnitTime*2^32 = HashesPerUnitTime a.k.a Hashrate if UnitTime= 1s    (as seen by the pool via valid submitted shares)

I know you were joking but some people don't seem to grok this so figured I'd spell it out for those folks who might be trying to figure this out for the first time.

I don't think this is strictly true.  If I recall correctly, a share of difficulty 1 is defined as a share with 32 leading zeros - which should, on average, require 2^32 hashes to generate, but will, in reality, vary from share to share.

on an individual share, yes you are correct..but over time it converges to 2^32 thus that's what all of the various software stats use for the conversion when they determine how much to pay for a share.  Instead, the "fast" or "lucky" share is represented as if your hashrate momentarily spiked so that the math of a share = 2^32 hashes is preserved on the back end.  So think of it as your "effective hashrate" which is seen by the pool that goes into those calculations.

haha well played, sir, well played Wink

But I guess the big take-away from all of this is that the stats being displayed on KnC's mod of cgminer are pretty much worthless unless you really want to do a lot of math.  Better to just ignore it and focus on what the pool is telling you.

My order is 4114 and apparently it was picked up today. If that means anything to anyone Smiley

Yes it does: my 39xx (was paid the same hour it was ordered) is not yet even started to be produced yet.  Huh Let's see if tomorrow will bring any news...

Paid mine instantly too, so numbers seem to mean nothing much. You didn't miss much today, there must have been an ASIC party over in Vasteras Sweden which my rig has been to all day...and still is. Look on the bright side mate, if thy can have weekend off they must not feel so rushed and there can't be many left to produce now and they've seen all the mistakes they could possible make hopefully ..so they may take a little more care and send you a well put together machine with decent firmware Smiley

and here I thought I was getting paid per share...

Since a share = 2^32 hashes, the two are interchangeable.

SharePerUnitTime = HashesPerUnitTime/2^32, thus SharePerUnitTime*2^32 = HashesPerUnitTime a.k.a Hashrate if UnitTime= 1s    (as seen by the pool via valid submitted shares)


Smiley Smiley Smiley

I know you were joking but some people don't seem to grok this so figured I'd spell it out for those folks who might be trying to figure this out for the first time.

I don't think this is strictly true.  If I recall correctly, a share of difficulty 1 is defined as a share with 32 leading zeros - which should, on average, require 2^32 hashes to generate, but will, in reality, vary from share to share.

on an individual share, yes you are correct..but over time it converges to 2^32 thus that's what all of the various software stats use for the conversion when they determine how much to pay for a share.  Instead, the "fast" or "lucky" share is represented as if your hashrate momentarily spiked so that the math of a share = 2^32 hashes is preserved on the back end.  So think of it as your "effective hashrate" which is seen by the pool that goes into those calculations.

Yeah, I understood your point - I just felt challenged to try to match your pedanticism. Wink

haha well played, sir, well played Wink

But I guess the big take-away from all of this is that the stats being displayed on KnC's mod of cgminer are pretty much worthless unless you really want to do a lot of math.  Better to just ignore it and focus on what the pool is telling you.

Alrighty, thanks for the attempt for the explanation all haha
Seems a bit silly that its even a thing for it to be wrong. But, with the way its setup, I cant help but feel like its expected. I can see the advantages and disadvantages of their little SoC board stuff for independent mining but I personally would've just preferred a straight to USB connection.

I'm not one for donations but if you must go ahead and I will keep you in mind. =)

yup, the straight usb seems to be alot easier..
The "plug & play" attempt was a total fail for me
I had an epic battle
it may have worked had the pool workername been correctly transferred, but as they say, hindsight is always 20/20.. I'm still happy with my saturns.

Seems like there is a big difference in "Monday morning" units vs. "Friday afternoon" units.  Undecided

It was particularly bad for me because my school's network only supports Cisco NAC compatible operating systems. Obviously this thing wouldn't take that so I had to bridge a laptop to wifi with it. Which is super unstable and hacky. Im afraid to touch the setup in fear of resetting something by mistake and being stuck with a miner that can't connect again because.

Almost no difference, in 2 and half day you wont mine much, so no big change in ROI if you keep your miner mining long

you are way off base here.. it's a quality of machine during manufacturing thing...but since you mentioned it..
I'd still rather have it sooner, than later... Smiley

but to add to Hemptsock's comment...
or a 3am saturday unit... with 30 folks staring down your back, and deadlines...lol
