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 saturn560 jupiter without doing that. Some people are having issues, but that's probably not related to heat.

wtf ?!
they send you untested broken crap for several $k and you have to pay for sending it back ?!

does this even comply with laws concerning B2B ?

Did anyone make a note of the running processes on previous versions, done a top on 0.98 and see a process called monitordcdc.

Was that there before ?

Jupiter Firmware 0.97 to 0.98 hash rate graph from BTC Guild (each data point is 1 hour):


0.97: about 320 Gh/s, 540 Watts at the wall
0.98: about 530 Gh/s, 640 Watts at the wall

For my troubled Jupiter, 0.98 handles the bad cores MUCH better... 200 Gh/s improvement over 0.97!

Thank you KnCMiner!  I recommend trying firmware 0.98, particularly if you have some bad cores.

Thank you as well, I encountered no problems with 0.98 and it increased hashing speed.

Sorry, but what would be the benefit on doing this? I'm not trying to be an ass, I really don't know.

It's not right but would you prefer to wait for them to get round to sorting it out ? Tomorrow means something entirely different in Sweden apparently.

A bit like manana does in Spain.

You're welcome, and thanks!

confirmed slight performance increase at the pool for 0.98
