The Chili – 30+GH/s BFL based Bitcoin Miner Assembly

[Taugeran]

Any good used Chilis with coolers available for sale? Most posts are pretty old.

Where might you be located at?

[MrTeal]

If someone wants to pay shipping, I have about a dozen bare boards kicking around that you can have if you'd like. They're just sitting on a shelf.
I do have a bunch of coolers for them as well, but I'd want $15/pc for the coolers and it would make shipping more expensive.

How efficient are they again with the low power flash? I disassembled my Chili awhile back, but now that it's cold upstairs I could use some more heat.

The turbo jallies did 5w/gh, the Single/60's did 4, a super low power and clock single can do close to 2w/gh. What's the current and speed for a Chili (running at full 40gh speed it was exceptionally inefficient but that didn't matter last winter).

I haven't really looked into it, but I doubt it's very low.

What voltage and clock settings did you use to get a Single to 2W/GH?

[lightfoot]

Everything I could think of.

Lowest possible voltage with resistor changes (I think it came out to .7v or so), clock speed 0, no fans at all, and replaced all the FETs with much higher efficiency/better matched ones. I didn't screw with the FET clocking frequencies, but I did get rid of all that heat. (what did I do, I think it was going to 1-2 high side FETs and 2 low side FETs. If there was heat, I was working on it.

It was a little putt-putt, but I did manage to get it down below the 3w/gh barrier.

When I downclocked the Chili with your code, I think I remember it being closer to a bit under 4w/gh at a speed of about 30gh. Since we never had the real code I couldn't futz with it more to bring voltages down to the bottom range.

I just bought this miner a few days ago from eBay for the sake of getting 30+ GH/s.

http://puu.sh/dENMI/02a9425b2b.png

I hooked this thing up to a 200W PSU and an Ubuntu Server box.
I can't seem to get it past 8Gh/s. The only time I see above 8 is when I first boot up bfgminer and it warns me about the temperature.
I have plenty of cooling for this thing, so I dunno what's wrong.

If someone can help me on this issue, that would be great.

The hardware error rate looks really high - is it possible that it may be defective?
Maybe try cgminer (you'll have to mess up your drivers with Zadig if you use Windows... ) and see if it performs any better with that? (if it does, let me know and I'll see if I can help fix BFGMiner..)

Try BFGminer version 3.1.1,that one worked very well....way back when

Good idea. If 3.1.1 works, it makes troubleshooting 5.0 much easier

Some Chili miners need to be booted from below 20c otherwise the power mosfets think it is overheating.
Also a secondary fan blowing onto the mosfet part of the board helps with power control.
BFGminer 3.10.0 was ok with my chili's

Was this one of the ones that Lucko had made, or is it an original Chili?
Try downloading the ChiliFlash utility linked at the start of this thread, and see if all the asics report as working.

I flashed the Chili with a few of the hex files, and it seemed like everything was working.
It gave me this:

Code:

DEVICE: Chili SC
MANUFACTURER: MrTeal and ChipGeek
FIRMWARE: 1.2.14e
CHIP PARALLELIZATION: NO
QUEUE DEPTH:40
PROCESSOR 0: 16 engines @ 0 MHz -- MAP: FFFF
PROCESSOR 1: 16 engines @ 0 MHz -- MAP: FFFF
PROCESSOR 2: 16 engines @ 0 MHz -- MAP: FFFF
PROCESSOR 3: 16 engines @ 0 MHz -- MAP: FFFF
PROCESSOR 4: 16 engines @ 0 MHz -- MAP: FFFF
PROCESSOR 5: 16 engines @ 0 MHz -- MAP: FFFF
PROCESSOR 6: 16 engines @ 0 MHz -- MAP: FFFF
PROCESSOR 7: 16 engines @ 0 MHz -- MAP: FFFF
THEORETICAL MAX: 33.28 GH/s

And then I update data once, and it brings the Theoretical Max down to ~ 19-20 GH/s.

I've also tried with cgminer, and it yields me the same exact results.

This is my current setup, I know it's kinda ghetto:

I'm wondering if I should get better fans for this. I need an excellent one for under $50 that'll do the job.

Is that stock Intel cooler making contact with all the dies?

A lot of the stock intel coolers have a round plug in the middle that's ~28mm in diameter.

To make good contact with all the dies you need a square base of at least 33mm. With the cooler pictured you'd have bad contact with the four center dies and no contact at all with the corner dies.

Oh, no it isn't. I'll need a better way to cool this thing though. Any fans you recommend that do the job (and are below $40)?

Coolermaster 212 EVO does well

[MrTeal]

To be honest with you, I wouldn't even spend $20 for cooling to bring that Chili back, unless you have a use for the cooler outside of the miner. Time has not been kind to the 65nm BFL chips which were power inefficient compared to the Bitfury stuff even when they started selling chips.

I have a pile of Chili boards, but at this point they really aren't even worth running with free electricity. It saddens me, but it's kind of the truth.

Can you take a picture of the bottom of the heatsink you're using right now?

[Mudbankkeith]

I have a stack of Chili's here in the uk.
Fitted with evo 212's.
I have been getting a better price for the cooler on its own, stripped from the board.

Even with free electricity, they are only worth running until better miners are available.

Mining hardware becomes obsolete even before they get dirty.

Any luck getting things working x86cam?
