Thank you!
I also got 3 of those 105d drivers instead of regular ones, and i was refunded, in the opened ticked a guy assued me there those shoudlnt be even in the store
And mine didnt have memory too
From now on will order 4 mode ones
I had the same issue and opened a ticket because I always use the stars for switch/offftimecap.
Put mine to good use 
Quite nice to have a symmetrical layout on top for stacking and making improved thermal paths. Glad I got a few of these by accident.
Thanks Werner, good to know.
Looks like FT updated their listing pictures for the 2-group '105c'. Yet to update the title, description and specs.
I don’t see what the extra three resistor spots are for.
Heh, interesting.
The stars on this version, while functional, are mainly for show. R3/R4/R5 are where you easily bridge each star to GND. A pick-n-place machine or assembly worker can easily place a zero-ohm jumper across those pads.
stars for bridging 
throw some 000 resistors on the pads, if you look close the star is connected to one side of the resistor pad, the other side is connected to ground
Most definitely odd, but interesting on the new revisions of the 105 *7135 type drivers
ding ding ding
105e seems perfect for the off time cap…but it’s the 20mm version so watch out…
and 7135 38s!
I was wondering how they achieved such good spacing from the edge… 20mm explains it.
I ordered a couple of these to try from FastTech:

8x AMC7135 generic driver with star-selectable mode groups:
A couple of interesting observations; the spring is much larger, making it much more useful than the factory spring on the 105c. Also, the above pic from FT doesn't show it, but the stars are printed in two pieces, so you just bridge the two halves to make your mode selection. I haven't installed one yet to check how the PWM, fit, and mode groups work out.
I’d sure like to see these sold with a threaded retaining ring narrow enough not to short-circuit components to ground.
Or — at least — specifying the inner diameter required for a retaining ring, to be used with the driver. And selling the rings.
ardvaark @ FT says that it’s not an ATtiny13A (pulled it off the board and USBASP wouldn’t play with it). - http://www.fasttech.com/forums/1127403/t/1002171/attiny-mcu
Yeah, you can see in the pictures that it's not an attiny. There are also cheaper ak-47 and ak-101 drivers out there that are nearly identical, except for the MCU. Apparently the "a" in ak-47a and ak-101-a stands for 'Atmel' or 'attiny'. When I was looking at having custom drivers mass produced, you can save about $0.50 per driver by using one of the cheap MCUs vs. an Atmel.
