Topic: The Habanero - 650GH/s - OOS - page 29. (Read 96051 times)

I'd look at seating the waterblock again.  My best results came with the block finger-tight plus a little(~1 turn).  Cranking it down got me higher temps.

With tons of air through the rad and tons of air on both sides of the board, you should be able to push it up.

I have used the stock coolermaster, AS 5, and Artic Alumina (ceramic based).  The Alumina is on there now. I did that earlier today.

The monitoring tool shows all 4 dies running... but I don't see a section that shows info about the engines.

Few ideas that jump to mind:

What thermal interface did you use?
Possibly need to reseat cooler.
Use the monitoring tool to see if all four dies have all engines enabled

My gut is gunna say one of the first two lines since for those temps at that speed seems odd

I'd like a chassis to mount a dual fan water cooler off to the side.. as well as mount 2 additional 120mm fans to give a huge amount of airflow across the top and bottom of the board.

I have a Cooler Master glacier with fans upgraded to Delta 240 CFM fans.

I added a TON of air flow across the top of the board and I can now pull:

MHz: 750
GH/s: ~550
Temp: 97, 98, 100, 96

Its a lot of air across the top of the board.

I am guessing that if I could figure out the cooling that this board would scale like yours up to 650 gh/s at 875mhz.
It seems like I am not doing something to optimally cool the board.

Hello all,
I know I'm a newbie, though I've been mining KnC from the get go.  After the Super Jupiter fiasco I have decided to go a different route.  Though during that time, the main problem people had with the Super Jup was the fact that the Arctic A30/i30 radiators weren't mounted to the ASICs properly.  I run a small shop and quickly reproduced the original mounting solution for the community. I know the last thing people wanted to do was spend more money, but in the short time frame and with keeping costs as low as possible, I had a lot of happy customers.  If you are interested in verifying, you can join the KnC forum and check it out.  I've got the same handle.
  I received my Habanero a little over a week ago and I'm in the process of designing an enclosure for the Habanero.  I am open to any and all suggestions, as well I've been following other users thoughts regarding air flow around the board, whether push or pull is more efficient, etc.  Though I know a few people who have received a completed HashFast product, most have run them with the case open.  That may be the best solution, though with all the components mounted in a logical and efficient manner.
  Good luck to everyone in their quest for quickness ...

That stuff is about as good as AS5, the benefit being its not conductive =)
and IIRC , I dont think it has as long as a curing time as AS5

What are you running for cooling?  Fan(s) blowing on board also?  Seems hot...

Stock Voltage
MHz: 875
GH/s: ~650
Temp: 87,86,86,85

Overvolted
MHz: 925
GH/s: ~700
Temp: 98,97,96,98

What about the AS ceramic? I got a bucket of that stuff running around.

Can you guys help with some board comparisons?

My board gets:

MHz: 600
GH/s: ~450
Temp:  100,102,102,98

What are you guys seeing at 600mhz?

As for now a higher MHz get me 105 and an overheat.

(I do want to figure out how to get the board up to 650 gh/s.)

AC5 is conductive...DON'T use it...

Thermal compounds...

I just happen to have a stick of Arctic Silver 5 lying around and was wondering if peppermining had any comments on thermal compounds to use or avoid.

http://www.arcticsilver.com/as5.htm

It is noted in the above url "While it is not electrically conductive, the compound is very slightly capacitive and could potentially cause problems if it bridges two close-proximity electrical paths."

I assume just dont' make a mess.

Mr. Teal, et. al,

I just had quite the thought (after trimming my hedges in 87F heat .... and no I wasn't "ManScaping" outside).  If for some reason you can't do a batch 3 of the Habanero boards with the HF GN chips (due the chips not being available) what would you think of a GroupBuy of the CoinTerra Chips and doing a board for those?  As I do the math the block of 525 CoinTerra chips should do around 236.25TH if you assume an average of 450GH/s per chip.  You could call this one the "Bhut Jolokia" board.  Hope all is well.

Yeah,  If I get one,  my plan is to push while placing fans perpendicular to the heatsink/board to cool the underside of the board.  

Here is hoping I get a chance to play with one =)  Any word on the testing yesterday? When are you all going to make the decision to reopen batch 2 or not?

I plan on pushing. The radiator will be mounted in a window to blow all the heat out of the house directly without my fans getting rained on.

You'd still want airflow/cooling over the VRM's. I personally would enclose them depending on how many you have.

[edit] and yes, pull is definitely more efficient.

Hey guys,

1st, thank you to sidehack and daemonfox for answering my earlier concerns on whether or not it is still profitable to bitcoin mine.
I do remember someone in this thread asking if it is better to push or pull air into/out of the radiator and so after doing some quick research it appears that performance would be the same whether push or pull and there is no reason to configure the radiators to push and pull(fans on both sides of the radiator) because you can get good fans which will give the same performance just pushing or pulling as if one would set up their radiator fans to push and pull.  The only upside to configure the radiator fans to pull is it will not dust up or clog the radiator with dust nearly as much as pulling the air from the radiator and it would be easier to, once in a while, clean the dust off of the radiator.  See the vid below:

I'm also wondering if it would make sense to enclose the habanero setups in a case/computer case instead of leaving them out in the open on the rig stations.  It seems to me that in an enclosed environment the air circulation can be controlled better with such a setup as taking any case, ripping off the front plate, covering the front full of intake fans and the upper back or the full back as well as the top with exhaust fans, the habanero setup can be mounted on long legs(so that there would be lots of space for airflow on both sides of habanero) to the case screw holes where the motherboard would go and  on the side door one could cut out a hole to mount the radiator, but just a thought, maybe it is not even worth going through all this trouble if there is not going to be a big difference in cooling or maybe in a full tower one can mount 2 setups of the habanero which would make things neater I guess.

I have used the Liquid Metal before between the die of my 3770K and the IHS. That stuff works great, you just gotta make sure it does not come in contact with anything aluminum. Have you noticed any differences between thermal pastes? I have been using PK1 for a while now and it works great, also the Timtronics Grey Ice works well, it is thick as hell but held up great when I water-cooled some GPU's.

Maybe I just missed the "sold out" tag last night.  I was having beverages while tuning the habs.
