What are the temps?

BAM... slow one still not quite done climbing, but Ewikis a happy camper now!
all 0.97, and no doggone fans... not even the case fans, only the heatsink fans!

In an apartment, In Dubai, may be a good thing... YaHoooooooooo

My experience tells me that the cooling industry is massive for a reason, the light that burns twice as bright burns half as long.
Is it worth risking killing them for a few extra Gh ? You won't know they're done until they die and jesus won't bring them back then never mind firmware.

omg... ever mined with graphics cards?  
60's is fine.  
the machines like it, and they are mine, and I'm sharing information for others to do with as they please, you don't like it, just ignore it, and move on...  no offense intended.
But since you mentioned it.. Ill have to point out that a few gh/s now is indeed worth it, yes, even if it cuts the life expectancy in half...especially since the bulk of your BTC are made at the beginning of the life of the miner, not the middle, or end....  

also, while we've been chatting... now 273,274,281...

Comparing graphics cards to these would be nice, but it's not logical. No graphics card ever hits the market without being tested to extremes, they are robust and well cooled apart from extra cooling we all add. These cards have no history or testing, and many aren't working fully as it is. I did ignore your experiment as my experience is the opposite and mine runs lovely at 37 degrees, it seems folly to me to take any further risk with something to valuable that is an unknown quantity...but some people might give it a go and regret it. If they know the risks that their perogative, but quite a few here are dipping their toes in the water and may just regret it.

It might be nice if KNC had some ideal temps for us, or ORSOC more likely....but I'm not holding my breath for that even of they do because they seem to have become mute of late lol

The diff doesn't bother me one bit. We all knew it was going to soar when we all hooked up these rigs, but imagine how the people waiting for pre-ordered machines elsewhere will feel now watching this? Quite a few cancelled KNC rigs due to this, at the last minute. It's possible that with evidence they now have that these other large batches from hashfast etc.may just see large cancellations too especially if they ship late.

Whatever happens, we're in the best spot now for a change..mining and not waiting or guessing like all the rest have to.

[Phoenix1969]

yeah, ultimately,  KNC will need to tell us what the recommended temps really are... good point.
Happy Mining bro

hi Phoenix1969 are you running .97 now?

[Phoenix1969]

yep, all 3
gnight folks

[carlotech]

thanks i will post my result soon...

[JoelKatz]

Because the ASICs are built on similar technology to CPUs and GPUs, it's reasonable to assume the range of permissible temperatures is about the same. The leaves two unknowns:

1) What temperature is the miner reporting exactly? Is it die temperature? Heat spreader temperature? Board temperature?

2) Should we worry about the VRMs overheating even if the temperature reported by the miner is in the safe range?

[DimensionsOfHell]

An update on my Saturn:

My average has settled around 142GH/s at the pool.

I've also noticed, possibly, why I am getting such shitty rates;



1. I have one bad VRM on the first board, and some really shitty cores.

2. On the second board, I have a bad VRM, and a non-functioning VRM


So out of two boards for a Saturn, I've gotten the shitty luck of receiving two shitty boards. So wonderful...


KnC's quality control people should be fired, that is, if they even have any. So this grounds my theory that they are no longer bothering to test units. They are just churning them out and sending them as they are, probably just to clear their back log, as they have already F**ked so many people over.

I'm going to stop rambling now; I'm just too pissed off.

[JoelKatz]

If the output voltage is correct and the current is low, it's not the VRM's fault. Check your VRM's for any physical damage. Check to make sure the plastic cover was removed from your heat sinks before they were mounted to the ASIC. What baffles me about your numbers is that your output voltages are so high, and evenly so across the board. They should be around 0.75V or so.

ok, then, I guess those will go next....

[ElGabo]

LOL

 

[demonmaestro]

LOL

 

Do you have that thing in a freezer or something?

[ElGabo]

No-No

Some modified cooling.

And about 18-19c room temp, closed box.

[demonmaestro]

damn a 65degree F room is cold.

[Mota]

I don't think 60°C are a problem. All my units run between 53 and 60°C with all fans on and standing vertical so that the warm air does not mix immediately with the cold air. And with a window over them so that fresh cool autumn air can come in. That said, 60° is also the temp my normal cpu runs with. I think they can withstand 73+°C without problems. My PS3 runs way hotter than that and is still working after all those YEARS. I do not expect my miner to run that long.

[Xialla]

yeah, indeed. ~60°C is very common temp for cooled chip running at 100% load..

btw downgraded to .96 because every ~12 hours after last reboot with .97, hashing speed drops from ~547Gh to ~450Gh. (.96 running stable ~540Gh)

[btc_uzr]

this is getting weird.....it doesn't matter how old are you, there's always sth not fitting into the picture of reality as you have perceived it until now
you put more heat onto those chips and get higher GH/s rate ?!

...and it is not recommended in intention to blow competition out of business   ?

[Puppet]

this "higher temp =  higher performance" doesnt make a lot of sense. Design aside, there are only two factors affecting performance:
- clockspeed. Is this variable on KnC? Can it be measured?
- number of functional cores/ % of HW errors. Does this go down as temps go up?

Thats it. The rest is statistical noise.

[waterboi92]

hey guys,

my jupiter is reporting HIGHER temps after i switched the heat sink stock fans for cooler master jetglo fans (95CFM). any idea why this is happening?

any insight is greatly appreciated! thanks.
