The Habanero - 650GH/s - OOS

[henriquelb]

Pepper Mining app is released! Read more about it at https://peppermining.com/pepper-miner-app/

Ill also be hanging out for a bit starting now on the freenode habanero channel.. join ##habanero and maybe I can answer any questions you have.

No words to describe it. Awesome work that you made, also all Pepper Mining team!

damm!  keep blowing the breaker.

DUUUHHH!!    120vac * 15A = 1800W

can't put more than 2 haps per circuit!

amazing amount of heat

Image snip:

BTW - I wouldn't run chilies and hasps on the same instance of cgminer.  I got a significant jump by turning off the chilies

Where is the PCB rear inch thick heatsink ? 70% of the heat goes thru the vias ??
Plus looks like your board is warping from pressure of waterblock...

Also On Carpet ? carpet holds heat in (insulator) place miner on stone or metal rack.

Great work on the pepper mining software!  

I'm running cgminer 4.3.4 on ubuntu 12.04 precise and can keep the temps down, but I'm having a little stability issue.  Happens on Windows or linux.

Miner drops out and then comes back as an HFA.  Tends to happen every 10 or 15 minutes.

Any thoughts?  https://dl.dropboxusercontent.com/u/30721962/HabCG-1.gif



edit: 850MHz at 90-91 degrees on all cores.

Is there any air running over the back of the board? The VRMs themselves require some cooling over long sessions if there's not a lot of air around the board.

Pictures incoming.

I'm having trouble getting past the 600-650mhz range with both my miners.
When I try to go any faster they start mining fine, then they reset with a "no valid hashes for over x secs" message (x = 6-7 or so).
Of course the time of the reset reduces the average hash rate to lower than I would get at 600-650 (420-460GH/s).

I'm running cgminer 4.3.4 on Minepeon 0.2.6, my options are as Gateway suggested:  --hfa-fan 100 --hfa-temp-target 0 --hfa-temp-overheat 110 --hfa-fail-drop 0 --hfa-hash-clock <number> .
My temps are ranging from the high 80's to the low 90's depending upon clock.

Anyone have any ideas?

BTW, Congrats to the Peppermining Team. NICE job! 

Can you show a picture of your installation?

I think I missed some info on the screws... what are the included screws for? They don't seem to screw down into the back plate. I don't see any other use for them.

That solved it, thanks.  Stable 900MHz at 90C, 650Gh/s.

I've got my Habanero hooked up to a Corsair H110 cooler. Currently I have the stock fans from Corsair on it. It looks like this:

https://dl.dropboxusercontent.com/u/20067231/Miner_v02.jpg

I'm mining w/ cgminer 4.3.3 running on OSX. My cgminer args are as follows:

cgminer.exe -o http://site:port -u <user> -p <pass> --hfa-fan 100 --hfa-temp-target 0 --hfa-temp-overheat 110 --hfa-fail-drop 0 --hfa-hash-clock 400 --api-listen --api-network

When I bring up the pepper mining app and look at dies, I'm seeing this:

Any suggestions? I've applied Antec Thermal Grease to the chips and torqed down the cooler.

[jimmychopps]

Xjack, those are some impressive stats! What cooling hardware are you using? Whats the ambient temperature? What thermal compound did you use? Sounds like you've got some high powered fans, any other tips?

[MrTeal]

For most people, you won't use them. They're the same M3 thread as an Intel heatsink, so you might be able to use the included hardware if it fits. If the hardware that came with the heatsink doesn't fit though, those screws can be used to hold down the cooler head.

Adding fans blowing across the habbies seems to have solved my problem.
Now I'm pulling 525GH/s @ 700 (for now).

Boy those boards get toasty without a fan!

Yeah, even with a 90% efficient DC/DC supply on the board, all those mosfets can be dissipating over 50W, which is a lot of heat into the board. That's the reason we finned the backplate, in order to help get some of that heat out of the board.

I took a few pictures on how to instal a Corsair H80i on the board.

FWIW I had almost the same problem -- ASIC 0 & 2 were 10-15 degrees hotter than 1 & 3. I tried tightening the screws on those corners and it had no effect on temperature at all.

I hesitated to take the water block off and reseat it because I had been very careful when I applied the grease the first time, it was evenly applied, no bubbles, etc -- but eventually that's what I did, and it's like a different machine, just 4 degrees of difference now. All I did was take the water block off, clean off the old grease, and reapply new grease. Somehow it just worked out better the second time.

Thanks for the tip.  I'll keep trying.

So the included screws are supposed to be able to screw down into the attached backplate. I think I might have to take pliers to them to get them to fit into the backplate.

The hex head on them is an M2.5, if you have a multi tool kit. I've noticed they can be a little hard to start, but once they get going they're fine.

The old "Redo" is always worth trying. I also noticed after tweaking several cooling heads that this process seems to work best...

1. Hand tighten them all down first.
2. Start hashing at a low clock speed and then tighten as evenly as possible.
3. Crank up the clock speed.
4. Loosen each corner until you verify a move up or down in temp to make sure that certain corners are not too tight.

I noticed that in many cases I needed to loosen certain corners by a turn or two to get even temps across chips. It's a bit like tuning a guitar.

My habaneros arrived today.

Thanks PepperMining that was a super quick turnaround.

Good work and congratulations to all involved

[hephaist0s]

Setting that up was a lot of fun. Thanks for another great machine, pepper-people.

[jelin1984]

Which is the hashing speed?
