When I first got my Saturn I removed the heatsinks, cleaned off whatever thermal grease that was there ( it was very thin stuff ) and put my own Artic Silver high density stuff on. Since then no matter if the temps are cool or hot I've always hashed on average 280-285. Top off, top on, fans on or on...always the same. Maybe the thermal grease or whatever they used was just inferior low quality stuff? After the grease dries up a little it should thicken up...when I received my miner the grease coming out on the sides was still almost wet. Maybe if you can't get your miner to hash up no matter what you do, try to clean off that crappy thermal grease that's there and re-do it yourself. AND REMEMBER, all you need is just a little eraser sized grease and not to over tighten. And I'll still not break even probably.

Did they do worse before you changed the thermal paste? I doubt that it's much of a problem, it seems like most people are getting  280 saturn /560 jupiter without doing that. Some people are having issues, but that's probably not related to heat.

I never trusted the grease that was on there to begin with, so I only powered up for about 20 minutes to make sure everything worked then changed the grease over to what I wanted. It could have been the same, but my Dad who has a Saturn also has great running speeds also and I changed his thermal grease as well. It can't hurt I guess. The stuff that I saw there just didn't look right. Very bright silver stuff that was almost wet. That's what made me change it to begin with.

Also, if you hate editing files while in SSH you can always do the lazy mans way. Download WinSCP and log into your miner that way. It's all GUI for those of us that hate text based stuff. You'll get a good feel of the file hierachy and it is easier to move around, at least in my opinion it is. I'll just download a file, edit it locally and then upload it. I hate VI. Also of course, you can download all  your files and make a nice backup locally.

You guys are gonna think I'm totally nuts... remember how I removed the ASIC fans??
Well, my basement is so cold that I'm now experimenting with freezer bags covering
most of the heatsinks.  lol  Temps went up about 5C and confirming more hash and WU.
Power draw is about 343W. Temps are in the mid-40Cs. I'm thinking maybe the ASICs
need to be warm, but the rest of the components should be kept cool. I put rubber bands
towards the top to keep them in a steady position after the pic. And check-out my peak
number!!! FM 9.8 and enablecores. I have not done a restart after initially putting the
bags on less than they are now.

I think there is nothing wrong with the thermal paste used on the knc asics, but yes they have used plenty which actually is not really needed but its pretty the same quality as arctic silver
This asics actually do like it warm, this does not mean you should remove the cooling. But when i put in 2 tornado fans which gave a drop from 62 c to 28 c on the asic cores it made them slow down.
The hash speed ended up being on avg 210 GH at that moment.
Before anyone asks NO the psu is not a weak one its a 1200 watt Antec so for this simple saturn even a bit overpowered with its 6 x 30 amp rails.

Now when i removed the tornado fans the hash went back up to 265 Gh on avg.

DHL is odd. It got to the states fast. Now its came to a craw.. 

[Biffa]

Hmm slush's seems to be suffering from a DDOS

[elasticband]

my knc is doing 800GH 620w at wall

[elasticband]

[ASIC-K]

actually, its not. its doing 550

[elasticband]

Yes I already knew this.

not sure how i feel about .98

75w more at the wall, and depressing specs 800/550..... back to .95 i go


edit: on second thought my HW rate has dropped from 10 down to 2% and my hashrate is staying pretty stable at 550gh/s

Wow!  In my opinion you're just asking begging for trouble.   

Do we even know for sure that the temperature sensor is located in the chip itself or somewhere adjacent?  You could possibly cook your chips and not even know it was imminent by checking your status page temps.

[edgar]

elasticband - wtf?!


xyzzy099 - are you able to amend

 "api-network": false

to

"api-network": true         ?



opentoe - thank you for - http://winscp.net/eng/index.php

DHL has lousy tracking in the US (great overseas) since they are a minor player here.  Your miner is probably just around the corner from your house.

Need to make it self to Texas first. But yea i know. I want it now damn it. Actually I wanted it the day i got it online.

If you already knew that why did you post a misleading stat? Either you don't know that the 800 is meaningless or you wanted to deceive people. The 800 means nothing whatsoever it could drop to 100 immediately after and your average would be 300.

I'm glad you guys are having good luck with the new firmware, but the increased power consumption is kind of a pain, hardly worth the 2% extra hashrate I got out of it

My guess is that the cost in electricity for the new firmware is less then the money you'll make from it

I never trusted the grease that was on there to begin with, so I only powered up for about 20 minutes to make sure everything worked then changed the grease over to what I wanted.

Why would you tell people do do something like change the thermal paste if you have no evidence that it actually improves anything? There isn't even any evidence that the chips are having any problems due to heating or even getting very hot at all, and you're chips aren't running any faster then anyone who wasn't having problems, most of which have been fixed with the new firmware.

In fact, at this point it sounds like the chips need to be warmed to a minimal temp anyway, in order to get an optimal hashrate.

[eiliant]

Not having much luck with Eligius today..

probably best just for troubled miners to run .98 then

[kronut]

Just a word of warning, if your unit is fine on .97 with cgminer 3.6.6, do not upgrade.

My Saturn lost 8gh/s, and 150WU on this upgrade, it disabled 7 cores that I previously did not have any issues with.

Going down to .97 did not fix it, I had to :

Downgrade to .97, reboot, run enablecores, reboot, factory reset, reboot, re-setup and update cgminer.

Back to 283gh/s after all this with WU 4060.
