The new top clock is 500MHz which is the highest I have hex values for.  That's pretty sporty for a USB stick as 425MHz was pulling about 2.5 amps on the USB port.
Yeah, things get a little 'interesting' electronics-wise Smiley  As sidehack mentioned, the connector isn't even remotely rated for that.

I've got a whole sheet of frequencies and hex values, but most of them are unlikely combinations of the various multipliers/dividers and some overlap; e.g. 200MHz fits 00111110000011 (0f83) and 00011110000010 (0782).  The latter is what is specced in the chip's datasheet - the series difference between them being the output divider value.  There's values well over 500 but I haven't even remotely approached 500 as it fails to initialize long before then Smiley  Looking forward to the new drivers - might poke at bfgminer as well, glad there'll be support in both Smiley

What kind of cooling would we need to keep a stick at 250mhz? xD

I've got a pretty weak 120mm fan cooling 9 of them, and they are maybe 10 C hotter than room temperature when running 250MHz- and this is in a hot shop, around 35 C.  Probably whatever fan you have is fine for a couple sticks, especially if you're only going to 250.

 
Excellent Smiley  Though I haven't had much trouble getting past 250, the new initialization routines should make it easier to get it above...wherever I left off.

Yeah, well, most people can't build cgminer or modify it themselves, especially on windows.  I've also got a stick to run 425MHz stable/low HW errors, although that just playing with one of the older ones.  It's probable you can beat that if you either get a slightly better chip, better cooling, or one of the v0.5s that you can't explode the chip by going into the "dead zone." (which would help you get a few extra mV).  The new top clock is 500MHz which is the highest I have hex values for.  That's pretty sporty for a USB stick as 425MHz was pulling about 2.5 amps on the USB port.

will you soon have a link to load the new version of cgminer.  I would love to run at 325 or 350.  vs 250.

Can somebody tell me how much time does it require to get your money back (ROI) ?
You won't - these are not intended to break even, let alone give you a profit.

Calculators are whack, but you can start with this sample simulation:
https://coinplorer.com/Hardware/Simulate/55e83fe0226bf410a453eeb0?key=4802c38f-0b0d-42da-a01c-5c288480c125

It assumes $25 to buy it (no shipping added), 16Gh/s at 0.35J/Gh (you can over/underclock), a constant difficulty (won't be so), BTC25/block (won't be so come half-way next year), no pool fee and no electricity costs.  You can see that the time for it to break even in those unrealistic circumstances is still 2 years from now.  Almost all of the aforementioned assumptions changed to more realistic values is only going to make that worse.

Thank you, and what i see Fun > ROI is very true Smiley

You will get your ROI right away when you turn it on and start smiling.

It meant it take lots of time thank you.

I'm guessing its not exactly efficient to run one for one usb stick but hey whatever. Lottery ticket man!
Better for multiple units, but then again, it's only about a 190mA draw for one of those fans (260mA stall; don't stall them Tongue  Also don't obstruct them at the back - you get airflow reversal) and given the FUN > ROI for even these mighty Compacs, yeah, it doesn't matter too much Smiley

A small fan will do.  I've always been a fan (hah.) of the Arctic Breeze Mobile [arctic.ac] - a USB-powered fan on a flexible neck for easy positioning with plenty of air movement and relatively quiet.  Though at 250, it's really not getting all that hot and even more silent options are available.  As long as you keep the hot air moving off of the heat sink, there's not that much difference between a gentle breeze and a hurricane.

Very nice then. I got 2 of those exact artic usb fan as a bonus for buying some hardware from a user here. I'm guessing its not exactly efficient to run one for one usb stick but hey whatever. Lottery ticket man!

I'll make a more official post but we should have our own branch of cgminer available by the time sticks are received- which is good news for you overclockers who want to push sticks over 250 MHz.

Value will be measured in sats
Is there a recommended USB hub to run these on?  Say for up to 10?  I am planning on using a Rasberry Pi 2 eventually but may start with a regular desktop PC.

This could run 9-10 @ 1amp each:

Comes with wall mounts and never gets hot Smiley

Yeah that paste sucks.  In the "things that don't suck" department the cgminer build is coming along quite nicely.  I should probably clean up the code a little (a lot?  It's basically a gutted icarus driver) but it runs like a champ.  I've also got a windows build done.  Luke Jr has also added bfgminer support so it looks like you'll have a good variety of software options.

Orders are confirmed and sales are updated.
Thank you!  Cool

but the extra money on expedited shipping.
Call customer support and demand a refund, they will give it to you since the package did not arrive when promised.  I've had to do it more than once.  If the package was insured they should also cover the replacement cost of the damaged goods up to the insurance value.  I think UPS default coverage on all their packages is $50 or $100, at least it was years ago when I used to ship a lot of car parts.

I'm having some issues with the QFN parts going down reliably. I'm guessing a lot of it is poor adhesion because the solder paste is basically shot. Solder paste is basically powdered solder and flux in a liquid binder that evaporates when hot, so it gets shipped overnight with an ice pack. UPS beat me to the shop by about 45 minutes last Saturday, and apparently the office is closed Saturday even when there are trucks running because the 800 number customer service people couldn't get ahold of anyone at the office or any drivers to let them know our $100 thing we paid an extra $50 to get overnighted because it was perishable needed to get here sometime when we're actually open instead of letting it sit and get ruined all weekend and arrive on Monday having wasted not only the cost of the product but the extra money on expedited shipping. Not too happy about that. So now I'm having to manually go back over pretty much every stick and make sure the buck, USB, ASIC and the big FETs are stuck down right. The ASIC is especially temperamental.

As of right now I have 21 completed sticks which need a bit of Novaking and a quick test and they'll be ready to ship. Tomorrow I'll be cutting out of work early (3PM instead of 10-11PM like the last 5 days straight) so I might not get a lot more done. But we'll see. If I can run up about half a dozen more tomorrow I can ship the first 8 small orders.

well how bout this one wait for link



it will do five

How come the price for EU lads are higher than the price for e.g. US blokes?

I simply can't compete with GekkoScience's in-house production.

The miner is decently calculated and the price includes shipping in EU.

Explained it in detail here.

He is trolling the thread!

Oops, I missed that posting, sorry.  I assume that if I erred on the signed message/address you will let me know when you get to processing orders, thanks!  Cool

I need to update my queue with recent sales. Anyone that's purchased in the last day, my wallet has to reindex (grumble grumble power outage) so I can't confirm purchases until it's caught up. There are at least two pending.
