The Habanero - 650GH/s - OOS

[MrTeal]

How much should I expect to spend on the power supply(s) and cooling solutions for one of these boards ?

I'd budget 200 bucks for a base level PSU and water cooler. Sky is the limit from there.

I'd say this is a conservative estimate.
You're probably going to want at least an 80+ Gold PSU ~800w which will give you ~85% efficiency and will cost you ~$90-130.
Then, you're probably going to want a decent water cooling system with double radiator and two 120 fans and will cost you ~$110-130.

While you may get away with the bare minimums as far as cooling and power are concerned, I strongly advise that you acquire my minimum recommendations. They may cost you about 25% more than just the bare minimums, but they will save you money and headaches in the future. Do you really want to be stuck with just enough power output and then there's a firmware update that can increase hashing power by 15%, but you don't have the juice to squeeze it out of the board?
Not only this, but high heat on the dies 24/7 will only decrease their lifespan and max load on the PSU will only cause it to burn out faster and may cause damage to the boards, not to mention cost you more in electricity.

You can never have too much power and cooling available.

I agree bit_ninj4.

My numbers came from using a Gigampz kit for power (80) and a Nepton 280L.   It might be best to use a PC PSU which has all the assorted connectors though. Some coolers require a sata power connector. And if you want to run more fans molex can come in handy.  So maybe closer to 300 is better.

So 1150$ for 640GH/s doesn't look so good to ROI this investment. (almost 2$ gh/s) I don't understand why it would good to buy those in terms or ROI.

1$ for 1 gh/s and this would be awesome !

Otherwise great project !

Yeah it depends what you're running. For 650GH/s a sidehack 750W is fine, though if you want to try to push 700GH/s+ you might want the 900W you get from the Gigampz kit.
For cooling I'm using a Swiftech H220 that cost me CDN$120 (USD$110) shipped, which is good to about 800MHz in a 30C room or 850MHz in a 20C room with the stock 55CFM fans. The Coolermaster Glacier 240L is an upgraded version of that which might be able to do 650GH/s on stock fans, I'm not positive. I'd probably replace the fans anyway though; especially if you shop on eBay you can get used fans cheap like these nice high pressure 140CFM Delta ones that you can buy 9 of for $56.

I know the Nepton 280L can do 875MHz on stock fans in a 20C room, though more air is obviously always better.
I'd say at least if you're in the US the cost would be much closer to $200 than $300.

Mrteal: I read the delta fans at first glance as 1400CFM. O.o added an extra 0 dope

I can confirm that a glacer with upgraded Delta 240 CFM fans can do 650 GH/s without any additional fans... as long as you point the fan output across the top and bottom of the board. Very loud.

Hehe, assuming a roughly linear relationship between RPM and CFM, that would mean a rotational speed of 37,000RPM and a blade tip speed of ~500MPH. Mind your fingers.

I have two new Delta 240 fans if anyone is interested. I opened and installed them yesterday, ran them for 2 hour, removed them and went back to the stock 280L fan's. They sound like jet engines and add a lot to your power draw. They do drop the temps a lot though.

I have been getting this error when the board is clocked at 850.



I am running the board on a pi with cgminer 4.3.5.

Is the board just getting too hot? I have not changed any voltages.

Need a few more specifics..

What is the temp of your dies, ambient temp, and are you blowing any thing over the board to keep it cool?
What is your voltage set to?

Also note at times ill be avail on irc channel ##habanero for any questions.. this is on a freenode server

While the project is not for everyone, if you already have the equipment needed to operate the boards and even if you don't, I haven't found a better ratio of hashing power to initial costs and operating costs than the Habanero.

Die temps are 0-95C, 1-94C, 2-91C, 3-97C. Ambient temp in my office is probably 80F. I have a fan blowing on the front and the rad is pointed at the back. Voltage is .86.

Raspberry Pi was the issue. Nearly 4 and a half hours on windows and everything is great.
Now if I can get something to tweak the voltages on windows I will be set.

I don't think it exists.

I don't think it exists.

@Gateway, @MrTeal: could we gain your opinions on whether the HF-Tool will/would work under windows. After a quick look. The tool is built from Python, uses pip to install pyusb.

Pip comes standard with Python 3.4 install. And the board identification code seems like it wouldn't be tied exclusively to linux.

Either willing to try it?

Have the latest batch been delivered?

[MrTeal]

They've all been shipped, likely some have not been delivered yet.

[ZBC3]

Did you get enough indications of interest to open up another batch?

[jasemoney]

Did you get enough indications of interest to open up another batch?

or enough left overs to reopen the tail end of batch 2?

[Two4D]

Can someone please post more pictures of those, they look really awesome

I have tried this. I installed the usb dependencies with pip and tried to run hftool. I got 'HFBulkDevice not found' about every second in a loop. I haven't dug into the hftool code to find what is causing this error, but I can confirm it doesn't work on windows.
