Topic: HashFast BabyJet users thread - page 44. (Read 69008 times)

Downloaded from setup.hashfast.com image.  Very different from what I had been given with the delivery 2 days ago it was a stock minepeon install.  Getting the updates now.  


 But you guys are updating the /boot/config.txt  which is removing the boot_delay=1  that allows this raspberry pi to boot without hanging at the Rainbow screen everytime a patch comes in.   Also if I needed to allow it to boot without HDMI to come back later to check on it, I can't turn that on, so either stop that update or update the config lines only you are trying to push please

If you are comfortable with linux, I recommend using a linux box to drive the modules.  So far I haven't had any unexpected reboots using 3.12 on an old notebook I had lying around.

More downtime due to MinePeon's inability to reboot the RPi, properly. I hope the MPP calculations include 20% downtime due to the RPi's inability to reboot properly.

cgminer 3.9 ran at 420 GH/s
cgiminer 3.11 ran at 392 GH/s
cgminer 3.12 is running at 410 GH/s

Does anybody have any lights on their BabyJets to let them know when the unit is off or on?

*** Feb 1/14 3:00 PM UPDATE: The RPi rebooted and froze four more times. I am getting tired of having to manually reboot this thing... So far, it has been running 12 minutes, which is a record since the auto-update to cgminer 3.12.

Pushed Where?   I'm still rebooting every 2 minutes

Thanks Minternj... looks like we are in the same boat as I have 4 on the way from newegg.

They are pretty similar but not the same. The H100i is louder than the coolit. You can actually hear the pump on the h100i. I'm not sure if that is a good or bad thing. Also the h100i lights up and has thicker tubing. Other than that the radiators  look the same. Cooling wise, no idea. I do have a spare h100i already, but theres really no point swapping them to test. We just need our MPP boards :/

I would love to have per die control. I'd assume fine tuning would help with the fluctuations i see in speed.

I guess this is probably a question for Phil... but anyone feel free to jump in.

I am preparing for the MPP (yeah, I know premature), and saw that newegg is running a sale on the H100i for $95.

Anyone know if there is any difference between the Corsair H100i, and the RACK DCLC?
The coolers in the BJ1 look like a H100i but the head unit says CoolIT systems Rack DCLC.

Also, regarding the chips liking being a bit warmer... is 70 the sweet spot?  Should I be worried if the chips go into the low 80s?

Also get a couple High Quality SD cards image them as spares, other threads here have found many many bad corrupted SD cards on PI's seems PI likes to eat them on improper shutdown.
Might be your issue also.

We are doing the best we can to improve the firmware.  One of the features we want to give you as soon as we can, is per-die speed control.  I can't promise it will give you more speed, but I'm hopeful it will help.

Engineering-wise, I can tell you with certainty that cooling it down more will NOT make it run better.  The only reason you'd want more cooling is if it's running too hot.  If it's going over 90C, then you can worry.  It will shutdown at 105C.

I've found almost without fail, the silicon likes to be warmer.  You'll see this by increased errors when you first bring it up and it's still "cold".  Once it gets around 70C it seems to get happy and the errors usually fall off.

FYI, We are using the Arctic MX-2 paste.  Our cooler heads arrive with no paste, just bare copper, as we ordered them that way.  During development, I personally did a compare with a bunch of pastes, including the Noctua NT-H1 and the Xigmatek PTI-G4512.  We also experimented with special exotic indium foil.  I found that among the higher grade pastes, there was little difference.  There was a noticeable difference from the stuff they normally pre-apply on the Cool-IT heads, which is one reason why we didn't use that.

What does make a difference is the right pressure, so we modified the mounting to achieve a more even and consistent pressure.  It's important that the screws be tightened all the way down until the shoulders stop.  You can easily verify this by backing them off 1/4 turn and re-tightening them.  When it stops, don't force it.

The reason I am bringing this up, is that some people had screws work lose during shipping, so it's a good idea to check this if you are having uneven temps or overheating.  BE SURE TO TURN OFF THE PSU FIRST, but I recommend leaving it plugged into the wall so there is a ground path.  This will allow draining of any possible static charge that could damage your rig.  Do not attempt this unless you are comfortable working inside electronic equipment!  I also don't recommend you mess with it if it's working well.

DO NOT ever remove the cooler head, as you will need to re-apply paste first!

Ok guys, I just pushed you Ckolivas' latest update; 3.12.0hf3 (with the RPI reliability patch).  Everyone should have it within the next hour.

We still have the strange hashrate reporting, but hopefully this will speed your rigs back up to were they were with 3.9.0, so let me know what you're seeing.

I also left 3.11 and put back 3.9 there too, and made a symlink so it's easy to switch versions back if you want to play with it.

No other changes.

Hi NiteShdw,

Sounds like you have an old version.

I recommend you backup your MinePeon settings (bottom of settings page), then reflash a new image onto your SD card, let it boot, then after 3 minutes or so it should have all the updates and then you can go back to the settings page and restore the backup.

Here are the instructions:
1. If running MinePeon, first make a backup from the Settings tab (near the bottom).

2. Download this SD card image: Windows: http://setup.hashfast.com/hashfast-minepeon-1.0.zip  Linux: http://setup.hashfast.com/hashfast-minepeon-1.0.img.bz2

3. If running windows, we recommend the Win32DiskImager: http://sourceforge.net/projects/win32diskimager/, If running Linux, you can simply type:
(Where /dev/xxx is the device name of your SD card.  If unsure, type "dmesg" after inserting your card.)

4. Boot RPI with the new SD image.  Note that it may take up to 2 minutes to collect current updates from us before it will begin mining.  You can browse here to see when your system comes online and what it's IP address is: http://setup.hashfast.com/.  If for some reason it doesn't come up after a few minutes, power-cycle it.  (We've seen some brands of SD card cause it to hang on reboot)

5. Log into the web interface and restore your backed up MinePeon settings (if any).  Note that the RPI will generate a new wallet when you first boot from the new SD image, and will begin mining using that wallet.  It's important to switch your mining settings using the "Pools" tab so that your mining proceeds end up in the right wallet!

6. If you have any problems, please post them here and I'll do what I can to help.  I'll try to check in here at least once a day.

I restored my minepeon settings and it completely corrupted my miner-start.sh file. Clicking "default" in settings doesn't replace it. Can someone post the hashfast firmare miner-start.sh file?

I Agree we should see a bit more OC to this High End Miner since its fame of being " Designed to be underclocked for greater efficiency, and overclocked for greater performance" off the description of HF site. DIY MOD tryout...  replace the water block on the BJ for something maybe abit more OC type. Hence a Water Block from koolance  EX2-1055 (Exos-2.5) Liquid Cooling System , 1000w rated ...

I haven't been able to get mine to clock over 580.  Anything above that results in either not starting or the USB device disconnecting every few minutes.  I guess some people just lucked out with better chips.

I'm also getting periodic kernel panics, which is not good.

I've seen a PCB with a 1.1 sticker on it, and one without.  What do other Babyjets say?  

(Look about in the middle of the PCB, at the top edge below the radiator.)

And, by the way, ckolivas, has anyone ever told you that your handle reminds them of bike paths?  Cklovias would be perfect, but ckolivas is so close.  But maybe I'm just slightly dyslexic.

Thanks for your continued support ckolivas! I really hope HF is compensating you adequately for your efforts.

The firmware is still in massive flux. I discovered that a few devices were released with work-restarts disabled because of the power draw problems it had, leading to much higher rejects than usual, especially on good old p2pool. Fortunately this has been fixed in upcoming firmware, but the ability to flash these devices and the newer firmware is not yet available. Not surprisingly things are still unfinished in the quest to get the hardware out ASAP, which I'm sure the customers prefer provided it hashes stable... I'm currently working on better thermal control which will work with the newer firmware and hopefully it will all be out soon.

warranty lasts only 14 days if i remember correct? so that shouldnt be an issue i guess.
