New MK808b owner.. questions.

[ididmytime]

Hello everyone,

Firstly, great forum, and I'm sure I'm not the only person who appreciates the finless rom. If anyone can answers any of these questions it would be greatly appreciated. I am using finless 1.7 and the 1080p kernel on an original board revision.

1) I am struggling to find any programs that will overclock correctly, with my goto SetCPU not working. Does anyone have any recommendations? possibly free?

2) When using something like CPU spy, it will constantly tell me my device is only running at the 1ghz frequency, are there any programs that will show the correct usage?

3) Is there anyway to overclock the mali?

4) I see a great deal of wifi fixes for the mk808, but not the mk808b, will removing the ground help the wifi?

Thank you.

Re ur #4.. the antenna ground leg removal...

I also watched the vid. it seems Finless noted poor wifi performance and popped his case open to see why. What he discovered was poor workmanship at the mfg soldering station.

Apparently, when the little stub antenna was soldered to the circuit tab, the heat was applied too long, heat transferred up the wire shield, and melted some of the insulation up inside the coax where it could not be seen, visually. This blunder effectively increased the impedance of the antenna by limiting the length of the radiating element, and causing problems.

It might indeed be a good idea to disconnect that one antenna lead from the pad and run a continuity check on the remaining wire stub antenna. Apparently, once disconnected, it should show an open circuit. I believe it's called a 'sleeve antenna'.

If discovered to be defective, it would indeed be a good idea to replace the stub antenna with a bit of suitable coax in the precise length, taking care not to overheat the solder connection.

If left with the ground disconnected, it may be necessary to mess with device orientation a bit for acceptable wifi reception.

A directly wired ethernet link will always be an improvement over a wireless link.

That looks like a great deal on a dongle.
Do you run that unit?
Do you get that transfer rate?
I'd like to see it tested with a benchmark against an ethernet connection.

Thanks for the responses.

Despite not being as mature as 1.7, I have switched to the beta, as it helps with ram usage and gpu acceleration for live wallpapers.

Managed to somewhat sort out my wifi issues, clipped and stripped the larger wifi antenna to just a cable and soldered a wire to the back of the ant pin. I get just under 50db, however, when I have placed everything back in the case, even with the wires pocking out, I still get a much worse signal, so decided to just run the device without a case.

Still trying to work out overclocking with the device, everything I seem to use believes it runs between 200mhz and 1.6ghz, which is a bare face lie, however, have no choice but to overclock, since my CPU is getting hammered by XBMC, and that is using the HW version.

my mistake... ERROR!

There is an error in my previous post.
I would like to make a correction.

I have just received an mk808... with broken internal antenna connection! lol

...The model I received does NOT have a stub antenna.
It uses coax for connection to a mylar printed circuit which is a plate antenna.

IF, the ground is disconnected, at the coax solder pad, that pad remains connected to a trace on the circuitboard which remains effective as the ground leg/base for the antenna. This should cause no harm.

I do NOT know about the B model, and you should investigate the circuit traces to determine if your unit has a ground leg.
