1.5 GHz DockStar

Postby Frex » Wed Apr 06, 2011 8:32 pm

For soldering iron virtuosi: http://gsg-elektronik.de/?id=96

The gist of it is the CPU clock and memory/bus dividers are controlled by what are essentially old style jumpers, only of course you don't have real jumpers (that would be too easy) but surface-mounted resistors that have to be resoldered.

25% clock increase and according to the text, the increase in power consumption is negligible. Text is in german so make sure you're using chrome or paste the link in google's language tools.

perfect. lol.

Long term impact on MTBF ?

$this->bbcode_second_pass_quote('WarheadsSE', 'L')ong term impact on MTBF ?


God knows :) in general overclocking is pretty safe because parts are just binned into different clock ratings, and different ratings having different prices and thus different demands, it's not uncommon for the lower rated parts to be technically indistinguishable from the faster offerings, especially if the process is refined enough, and the Feroceon has been in manufacturing long enough that might actually be the case.

$this->bbcode_second_pass_quote('mikestaszel', 'I') think on the bottom of the page he says this makes the Dockstar really unreliable and he advises against it. From what Google translate says, it seems he can't get even md5sums to generate properly on 1.5GHz.


That's not really surprising, the Dockstar gets pretty hot even at its default clock. Not that I'm above cutting a hole in the case and slapping a heatsink on top of the SoC ...if I could solder SMDs, that is :lol:

$this->bbcode_second_pass_quote('mikestaszel', 'N')ow, if someone could just solder on 4GB RAM...


No way it can't possibly address that much... can it? :shock: :lol:

If that would be possible for downclocking ( to something like 600mhz )
that would be awsome for me. For what i need dockstar, i really dont actually need 1.2ghz.

I don't know about 600 MHz, but 1 GHz should be easy (as long as you can solder SMDs). I guess it'd be hard to see any actual difference at the... plug ;)

BTW are there any known reliability issues with the Dockstar?

For 200mhz i dont see the point messing around with soldering; last time i soldered something ended bad for my finger ... :cry:

Best way would be if these values could be controlled by software like leds..

Can you up the vcore, change the multiplier and memory timings?

Better apply arctic silver to all heatsink surfaces and run mprime on it overnight.
