Oh hey, cool. Say didn't someone start a separate thread for this?

I love the bit of sarcasm, actually I started the thread for the overclock competition but since about 117 posts on this thread were "show off" posts I thought I would add to it. Apparently, that is frowned upon, or at least when I post them. Deleted the post

Oh, okay. I wasn't sure if that was a general showoff or if it was showing off for the overclock. Also it was fairly general, since a lot of the last page was just folks talking about the overclock competition.

Check the voltage on the reset testpad. There's a resistor and capacitor in the right corner immediately below the heatsink, make sure they're intact.
Sorry, I'm not too experienced with this. Am I looking for a resistor and capacitor underneath the heatsink after I remove it or before? Which are the reset testpad? Pictures: https://imgur.com/a/tOHbY

Not underneath the heatsink, below the heatsink Slightly closer to the USB connector than the edge of the heatsink. The reset testpad is the pad on the back labeled "reset".

A visual inspection doesn't show any clearly damaged areas, but I've included more pictures just in case. https://imgur.com/a/tOHbYI measured the voltage using the reset testpad and these were my readings: VCORE: 0.55 V 1V8: 1.80 V 0V9: 0.48 V RESET: 1.61 V

Thanks for the suggestion. It seems like the pot was turned quite low as a result of my fiddling. I've turned it back up and have VCORE at 0.70 V, other readouts are identical to before. However, still no dice on seeing the unit mine yet.

So your 0.9V is reading at 0.5V? That's very not right. Poke around on the legs of the SOT23 LDOs over on the side there and see what you get.

I Google'd what a SOT23 LDO was and there was only one on the side that I saw. Let me know if I measured the wrong points or if this is completely off. These were my readings:

Alrighty, well yours is the new version without a 0.9V LDO. The two resistors right above it (331 and 471) are a voltage divider that gets your 0.9V line. I don't know why you'd see 0.48V on 0.9V (after testing some 400 current-version sticks I've never seen that error) but it could be a problem there. If those resistors are seated correctly and doing their job, it must be something broken inside the ASIC.

Does it initialize but the white light never once flashes? If so, it's a bad connection between the ASIC and PCB.
It's funny because for a short while it hashed out of the box. Then I started running into this. But yes at the moment it does initialize (light up) but then never a single flash. I need to do further testing - I got the same error no matter which port on the hub I used, nor a usb port on the server. More testing to come. I'm going to knock the voltage and frequency way back and see if things play nicer. Second stick from this batch is acting up now. [2016-02-21 13:09:16.037] COMPAC 2: No valid hashes for over 10 secs, attempting to reset [2016-02-21 13:09:16.217] COMPAC 2 attempted reset got err:(0) LIBUSB_SUCCESS BUT - again i haven't had the time to rule out the superpbag so I'm not making any conclusions. I just need time to test. Buddy picked up three of these I believe and he's having similar issues with two of them. He's doing similar testing (might be issues with the superpbag).

Thanks for looking into it and responding quickly. I checked the 0.9V connection on the other 3 sticks and they show between 0.90-0.93 V, so this one does seem to be the odd stick out. I'll PM you for further steps to take for repair/replacement.

Maybe that particular Superbpag. I have three sticks on 325 and three sticks on 275 on S-pag and they are all stable for 32 days and counting.

I'd like to say so - but mine is the same issue (another superpbag) - but we purchased them far far apart.

I'm running on a linux server (ubuntu 15.10) that is an old repurposed desktop with a 7-port superpbag hub using y-cables to three sticks.
Each stick is set to about .77 and I see this error with freqs from 250-350 (i don't touch the voltage in between).
The original compac stick has always run on this hub and it never has a problem.
Stick 2121 never initializes in cgminer anymore - the light goes white then green and then stays there. Tried dropping it into a windows machine and no difference. If i take my original stick (268) and toss it onto that same windows box - works great.Stick 2125 generally plays nice but HAS gone off into the weeds once or twice. Stick 268 has never had a problem on any machine / setting.
I have taken 2121 and put it directly into another USB port on the server and jacked the freq WAY down - nothing. I've tossed it onto a windows machine - zadiag and all. Cgminer never can detect it.
such a weird issue.
i had linux close to perfect for more then 4 months now the one stick. When I mail it maybe sidehack can find out issue. some eye candy here is a block won by me . yeah it is an alt coin yeah it is worth about 25 usd a block but still it is fun. https://i.imgur.com/Mtkz76H.jpgCongrats on the block Phil! i've been mining there too.

My windows computer won't recognize the gekkos. Can somebody post a link to where I can download the drivers? Trying to use zadig, but it can't find the device. When I tell it to list all devices, the gekkos don't show up. Thanks in advance.

No other drivers than Zadig. - you should have new HW detected when you plug them - if not there's something wrong just right there - if they are, install zadig for the appropriate USB component - then run the gekko version of cgminer (of bfminer 5.4.*)

on zadig you may have to go to options -> show all devices and it should be in the drop down
