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

[x86cam]

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?

What do you mean?

What do you mean?

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.

[MrTeal]

Any luck getting things working x86cam?

[Miningstore]

I'm sorry, please help me understand how these chips work, can I plug this into a motherboard that I can buy from Amazon or Newegg, and use it almost like a mining GPU?

This thread is nearing 3 years old. There is no useful information to be gained here.

[lightfoot]

Well there's a lot of info, but these were great in their day, not so much now. Basically they take 5w of power to make 1mh of hash, 30mh per board, for that same 150 watts you can get about 1gh using a .15w/gh s9 or whatever.

Or find a couple of Sidehack's 2PAC usb stickminers... about 12GHs on standard USB power of 5v 500ma or 2.5W... Still only good enough for solo Lottery mining but beats the pants off of MHs speeds...

Odds are BFGminer might still support them, I know it ran my 10GHs BFL Jala's.

I remember those. I had so many. I wish I kept a few for show and tell.
