Just before the weekend my Octows2811 SD/Ethernet adaptor board arrived so I immediately went to assemble them to my Teensy 3.2 and tested it.
Currently, also with the OctoWS2811, i'm still abled to only let 170 leds be controlled simultaniously.
I've uploaded the 'BasisTest' example from 'PaulStoffRegen', and adapted it a bit (number of leds, etc.) to fit my setup.
When entering more than 170 LEDs and uploading the code, nothing happens on the LEDs, they all stay 'black'.
When entering 170 LEDs or less, the code runs fine and the correct amount of LEDs light up according to the test loop.
The same thing happen with the ArtNet example.
To eliminate any minor mistakes or typos in my used code, i'll copy-paste the code from the IDE below.
Does any of you have any clue on how to get more than 170 LEDs driven/controlled?
For information, all LEDs (currently 204 pcs) are in series (regarding the data line), fed from the orange+orangewhite cable from the RJ45 connector in the OctoWS2811 as mentioned in this page.
Power is supplied to each column of 17 LEDs separately from common + and - rails.
Thanks in advance.

Required Connections
--------------------
pin 2: LED Strip #1 OctoWS2811 drives 8 LED Strips.
pin 14: LED strip #2 All 8 are the same length.
pin 7: LED strip #3
pin 8: LED strip #4 A 100 ohm resistor should used
pin 6: LED strip #5 between each Teensy pin and the
pin 20: LED strip #6 wire to the LED strip, to minimize
pin 21: LED strip #7 high frequency ringining & noise.
pin 5: LED strip #8
pin 15 & 16 - Connect together, but do not use
pin 4 - Do not use
pin 3 - Do not use as PWM. Normal use is ok.
This test is useful for checking if your LED strips work, and which
color config (WS2811_RGB, WS2811_GRB, etc) they require.
