I'm in a cool bsmt 62F....I have 2 5" er I guess they are menard fans pointing crossways across the front blowing with cover off with.95 and it is sitting at 568gh or so...my cores are like 20c 34c and 41c for last 2...

i'm the doppelganger of phoenix's units I turn off 1 fan and my hash rate goes down ..I leave everything alone and I two will get the dwindle down effect but usually only a couple gh or so....

it is pretty much stable as long as I continue to keep the jally I got on haloween (april order) at other end of the house (only explation bfl units are evil)

so yeah shut a fan off and gh goes down turn fan on goes back to where it was

only other thing is I think I only have 2 cores go on/off  or I've only seen the two once every 3hrs or so for 1 ...once a day maybe for the other (guessing)...it is likely more

so again it is DRY in my bsmt ..ie winter is coming....Phoenix is in Hawaii ...could humidity have something to do with all this ie...with his box setup he is probably moving more air then me and it is probably a lot more moist

other then that ....I try to stay as far away from the unit as possible less I trip on it or something foolish

Searing

just updated my mercury from .98 to .98.1 and HW errors went from 6.9% to around 1.5%. also, rejected was 3% to 0% now!

definitely a good upgrade. all cores functioning as well. none are off.

UPDATE: been running .98.1 for 30 mins now, hw errors down to 1.1% and dropping. still no duplicate shares!

Not to poke a lion... but I personally Mine for fun, in hopes of a profit...

Right...

From "promising sound currency" to " bio-eco-super tomatoes" to "independence project"... No, I cannot really "twist" something you already did very well.

So, again, why would anyone want to convert BTC to fiat money?


So, again, going back to the context of that reply, you are mining for profit or for fun?

Yes, that is just how they run....
I'm not sure if anything can be done about that.
Even when I did graphics cards... That was the "nature of the beast"
Each and every unit does it...all simultaneously, but at their own top/bottom values.
I'd say, the cycle varies from a minute, to 3 minutes, depending on the flushwork/block detection timing.
         ********
But I also noticed there is still a bit of room for improvement in the flushwork area here... they flush every time a block is detected, instead of the correct block....every block.
I'd rather no flushwork at all, and take my rejected shares at the time a block is ACTUALLY found by our pool...... if it can't be corrected... it would save time.
Pools will usually send a flushwork request at the appropriate time if I understand this correctly....
I'm sure someone must be working on this....   hopefully....

I'm certainly no expert on this so I may be completely off-base here.  But isn't your pool hashrate just an estimate by some complicated equation including shares submitted, share difficulty, yadda, yadda?

If true, this might cause you pool hashrate to have some significant swings that aren't necessarily indicative of your machine's actual hashrate.

My saturn has been hashing steadily at the server between 270GH/s-290GH/s.....chip temps are between 45c and 55c, depending on heat of the day. Not running a/c, lid is off, all fans on unit are running, no extra fans and now at 20M submitted shares 2.5% HW errors, WU 3982 since last reboot.

ps. what i wanted to add was that I do notice a small wave pattern in the hashing speed of the unit where it slows to 270GH/s, then slowly crests its way back up to the low 290GH/s and then will creep back down to 270GH/s etc etc.

oh yeah, its doing great. hw errors bring it down to about 137-138 on the pool...still not bad!

If I'm not mistaken, 144 GH/s is the theoretical maximum hash rate for a Mercury (192 cores @ 750 MH/s each), so you are doing very well.

my mercury is running the exact same. take a look at your hw errors and rejected tho, mine are around 7.7% hw and 3% rejected.... :/

Sounds peachy, just leave it be.

Based on your hashrate your machine seems to have a ridiculously low level of hardware errors so I would say it doesn't matter, in any firmware, for you.
  

142 is great for a mercury...  I wouldn't touch a thing imho
If you're  "up to spec", (and beyond) why bother?

In my personal experiences the temp does not seem to matter. I've run my Jupiter at 70C and in a cooled server room with case off and external fan at 35C with no noticeable effect on my hashrate.

I have missed a few threads here, I know, but is there a current consensus on the ideal temps for these miners. I have a Mercury. Its pootling along at a steady 142 Gh/s at 39.5 degrees C. Sound ok?

I should probably stop replying to you but just because I don't want you to dumb down what I think is an important factor often disregarded, I will put it very explicitly and simple so you can't twist it around:

I was talking about the psychological drive, shared by many people, of building their own little growth and independence project that may or may not return. Those often grow quite large and into totally unproductive projects (measured in terms of "paying debts") such as growing flowers for fun. The drive is the same.

What I did personally is irrelevant but like I said I successfully fought the temptation of getting into the BFL scam and a few others. I always tried to see it rationally as a pure investment but we all know by now that the most rational thing investment wise is to just buy Bitcoin for the price of your miner instead of ordering it, don't we?  After Sam's announcement of queue trading, I bought an early Day 1 order so that I would maximise my chances of ROI (which actually payed off). But the fundamental background psychological drive that is blind to pure rational ROI considerations is there. In me and, I would dare say, in nearly everyone else ordering a miner.

You don't have to look very far to see this drive affecting people's investments here or anywhere else. The degree to which it does affect them varies but it's there. Here's a quote from a few hours ago:


Sure, 1 BTC is not much, but proportionally a lot worse than a Jupiter pre-order. Call it a vase with a crippled tomato plant that your friend sold you instead of a green house bought from a specialist contractor.


Since Bitcoin mining is a zero sum game, hobbyists will actually have an impact against pure profit driven mining farms. This is actually good for Bitcoin because it works against  centralisation of mining.

 

Croppo...  Please get some coffee & relax.
Our "Tomatoes" have a very long shelf life, and tend to increase in value over time...
It's a hobby this "growing tomatoes", and everyone eats them!
No worries!

So let me understand. You got a KnCminer SHA-256 hash generator which consumes a great deal of electricity because "people pay tons of money for backyard greenhouses and perfect soil to grow a few over priced tomatoes"?

 

Exactly... It seems the dwindledown effect happens weather the units are kept at peak temps or not...  cold or warm... it just happens... ug!

just the stats page...  they still mine from a separate server...
