Also, following up on the Chili that died during a reset gone bad (short pins 5-6 but must have also touched something adajacent)... I replaced the FTDI, so now two parts are working:
1.) The boot up light sequence appears to be functioning correctly, so I would imagine that most of the Chili should be in good order (was working right after I lost comms/hashing, too).
2.) The FTDI seems to work. I can see the device in the USBs and in Windows I can *try* to read or even flash the firmware, but I get garbage in the results window.
Something else must be dead, but I'm not sure where to go from here. Ideas, anyone?
Topic: The Chili – 30+GH/s BFL based Bitcoin Miner Assembly - page 19. (Read 138078 times)
So, with my rooms being nice and cold now, I finally ran into the situation where my Chili would overvolt. I installed the e1v1.hex to limit the voltage, and it works, but I definitely take a hit - about 5% or 2 GH/s. I see 4 places where the e.hex differs from the e1v1.hex file, and I was wondering if I could just get a bit of the voltage back since my units run so well. But it's not clear what to change. Thoughts? I'm thinking 1.14V would be a better limit than 1.1V since mine runs well up to 1.18V.
Can a firmware file be posted that has a different limit? Or a guide so that we can put in the limit of our own choosing?
Thanks much!

Most of my best performers are working well between 1.14v and 1.16v

Thanks for that picture. Your errors and submit ratios almost exactly match my unit, so I can say mine is working normally. I still am getting a good 39/36gh rate out of it with the water cooling heatsink, best $50 I have spent.

Mine are just using the EVO212 heatsinks with the Recommended Padding (not even arctic silver)
Fun stuff.

i have win xp
i must install something else first?

?How about installing an OS that's less than 13 years old?
Almost 36 Days uptime. Solid Units.
Looks like you would have almost solved a solo share (1.14G)! Or depending on the difficulty at the time maybe you would have.

i have win xp
try to install win usb drivers with zadig
but failed to install;
why that happen??

? I've noticed that myself primarily with cgminer, that if cgminer crashes/exits the unit will sometime hang. We're looking into where that might be happening and hope to have a fix in for the next firmware release.
Thanks. If it helps, I noticed that killing bfgminer with "pkill -9 bfgminer" *seems* to cause this behavior more often than with "pkill bfgminer" which lets it exit a bit more gracefully. I've got like 3 or 4 cards that all of the sudden are showing 250GH/100% hardware errors?
I have them off now and will let them cool completely down before turning them back on.. But reading on here that some people solved this with firmware reflash's.
Do these cards get in situations where they need to be re-flashed? Or can a reboot always get them "back"
I am currently running the 14e flash that has the 1.1v limit.

Mr Teal or anyone "in the know",
I start and stop my bfgminer quite a bit, but often one or the other of my Chilis doesn't come up again and I can't add it manually. I have to do a hard reset or power on/off to get it to reboot and get seen again. Restarting bfgminer or invoking it with --force-dev-init doesn't seem to do the trick.
My question is there any way I can force it to reset via a commandline so I don't have to wait until I get home from work or whatever? I know the devices are on /dev/ttyUSB0 or /dev/ttyUSB1 and when they're working, I can see some output if I cat them directly, but I get nothing if it's hung. Any ideas to force a reset remotely?
Hmm, on a whim I just did:
and now a few minutes later when I started bfgminer again, it CAME BACK! It's never come back from a hangup before, so maybe that did it? Or was this just a fluke?
Anyone? Bueler?
edit: spoke too soon - it was recognized for a bit, but NOT hashing. then trying to restart from within bfgminer just made it disappear again. Argh.

Question -
What is the max amperage provided by the 3 pin fan power ports on these? I've got a pretty hefty fan I'd like to point along the edge to keep the FETs stuff cool. It is however a 2A fan and I don't want to overdraw anything. Thanks!
The PFET is rated at -4.2A at 25C (-3.4A @ 70C) so you should be fine. It's had no problem running a Thermaltake Water 2.0 Extreme CLC that draws 20-30W, so I think you'll be fine.

Not really. I have a 4 chip board that I play with that is similarly limited, even if I only run 2 chips on it. It's more a function of the BFL chips being broken, the highest clock divisor doesn't work so you reach a maximum frequency setpoint and then can only vary the frequency using the voltage. There's a limit to how far you can push the voltage though.
Do you played with external clock injenction to the test clock pin? I mean I saw in documentation the internal clock can be overridden by setting external clock on this pin. Also it is described as an test pin.Cheers...

So, in anticipation of that, what is the exact part number of the FTDI chip that I should order, and possibly from where? I do have a hot air station, so that part will be easy, but what temperature should I set it at so as not to melt the chip body?
Thanks in advance!
For chips with legs, I'd go with 400c for 30 seconds tippy tops. See how long it takes to get them off, then use a bit less than that to get the new one on.Thanks in advance!
You don't need anywhere near as long heat for the chips with legs.
Perfect - thanks! I actually just ordered that just in case, but good to know I was on the right track!
