I have a couple questions regarding my 3 compacs.
I have them running at 300mhz and the pot at 9o'clock without any hw errors. But my killawatt is measuring each at about 10.5watts or 32watt total. That sounds high right? Was expecting 7watt range.
Also measured the heatsink passively cooled and it is reading 90ish deg celsius, after 2 minutes. This is quite hot. anyone tried mounting a small 50mm or 60mm on each sticks heatsink, and how low do the temps go?
Tks.

(and I have no idea why imgur isn't doing anything other than a link - noob)
Because you do not have enough posts
Thanks for the explanation!
Is that a big deal? Should I bridge it down?

I check for that, but I guess one slipped through. Yeah, make sure it's tied in. Shouldn't be a problem; I overspec'd the output caps pretty good for ripple and stability but if it's there it might as well work right?
Will across to its neighbor do, or do I have to go down to the board? its a large gap, I don't have hot air, and to heat that much mass i'd need a big tip at a moderate/high temp no? Its a Weller adjustable pen, I'd give you the model and tip info but I can't lay hands on it now, but i have 0.25mm tips up to honkers at least 1.5 or 2mm across if not larger, lots of mass to them. Temp pot (analog) goes from like 550/600 to 850/900 I believe. Probably would need a new tip, oxidized to hell and back it would be by now.
I might could melt the down side and push the cap down closer to the board on the up side. Its already touching (if not soldered) to its neighbor, and continuity is good (strong constant beep, 0 on the meter), resistance shows the same between middle and left (both on their pads) as compared to middle to right (one up one down) at .9 ohm (on 200 ohm scale).
If down to the pad, flood it with enough solder to fill the entire gap? Or try the push down mentioned earlier?

I know....
but as I said, I don't trust myself to do it perfectly.... and this has to be perfect, there's no room for mistake.
- I don't have spare heatsink (which is a mistake, I could have ordered a couple more)
- If I F*** up the last bits, then I have to re-do everything as all 3 sticks are side by side, and with that I increase the chance of making another mistake.
- drilling/tapering aluminium is tricky
- hole are to be drilled at 0.5mm precise point.... I don't have anything to measure at 0.5mm..... and to be acurate I would need a decent press drill
- hole/thread have to be perfectly vertical for good pressure on the stick without damaging the chip.

yep I keep having ideas...
Now I just brought my 2 heatsink to be drill/tapered at the local workshop....80$ ( for 2 heatsink paid 6$ :p)

well, 13 days later and the job is not done, so i collected my untouched heatsink.
Alledgedly the guy didn't have time to do it.
i understand I'm not a high priority customer, but that was a quick and easy job for them and money on the side as I didn't need an invoice.
Well, i guess they won't see me for other project I may have.
I will ask my godfather as he's in this business and he'll do it for free, although he lives 35miles away... so 2 return trips...
for 80$ you can buy a drill bit, punch and a tap and do it in about 20 minutes..

I encourage anyone who might be having issues to first look through the first couple pages of this support thread, try the search bar to see if info is posted by others about the same problem you're having, and then if you still can't find an answer ask me directly but be prepared to give detailed information, the acquisition of which might actually require you to learn some new things. And then if we can't get it going I'll tell you to send it back for repairs, and what the process for that is. Don't just start mailing me broken stuff. Unless I know it's coming and who it's from and why, I'll assume it's a birthday present and you won't get it back.
But yeah, the other day I fixed three sticks. One had a bad ASIC, one had a manufacturing defect (whoops), and three (from the same guy) looked like they had been overvolted on the USB jack which cooked a USB chip, two buck drivers and an ASIC. His was either the bad ASIC or the manufacture defect, but I'm betting it was the bad ASIC since the other one was actually a first-run (V0.5) stick and the part in question has been removed in the current batch (V0.6) design.

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.

Quick follow up on this. I sent the stick back to sidehack as none of the changes / testing I made showed it working in any manner (the other batch 2 stick that I have is happily hashing away).
He turned it around within a week and its on its way back to me. He believes to have found an ASIC problem (if he remembers correctly since he did a number of repairs around the same time). I encourage anyone who might be having issues to send them back to him and be patient. He'll get the issue sorted and get it back to you. Great service (not surprising at all).
I'll report back once I have it and have tested it.
I found a freakin block with a Compac on Bitminter -- 
Nice, now don't you wish you were mining solo :p
I do- I will post pic tomorrow
So.... got the picture showing a block solve on the compac stick? It's quite a claim to make and then let a week go by without supporting evidence.
I think my Compac may have seen it's last day 
A while back my compac stick got bent at the USB connector and I gently bent it back. It was running fine after that until a few days ago when it went Zombie on me. I unplugged it, and plugged it back in and windows didn't recognize it nor did cgminer. I unplugged and plugged back in several time and cgminer eventually detected it with "Gekko detect" but it wouldn't mine do I used zadig to reinstall the driver. It started mining away again and I thought all is well. Then came lastnight and it is now just an unknown device after I did a PC reboot.
Any ideas on how to get this guy running again and/or how much would it cost to have it fixed if the failure is from it being bent?
Thanks for reading.

How bad was the bend? Maybe resolder the usb connector? it isn't that hard.

Seems to be sold-out everywhere... If they are being sold the prices seem to be much higher than the initial $25USD. holybitcoin.com is selling broken "DEAD" miners???

Wow that's awesome !!! Do you have a screenshot ?
Well, the manufacturer sells them for $25. Everyone else has the added costs of shipping, and advertising, and some necessary markup to cover their own overhead. Lucky there are no additional middlemen between me and HolyBitcoin and CrazyGuy and such, or prices would be even worse. Stupid middlemen.
