This is the email reply I got from Beelink this morning.
It came after many days of emails back & forth during which they denied there were two versions of the GT King Pro out there.
The default frequency of the S922X is 1.8Ghz, and the overclocking can reach 2.2Ghz. However, because Amlogic claims that the S922X overclocking reaches 2.2Ghz, the product will be unstable, and the chip will overheat. Some problems occur during use, and 1.8Ghz is stable. The best frequency of operation, in order to maintain the stability of the product, we began to set the default frequency of the S922X product to 1.8Ghz.
If the customer wants, we can restore the firmware running at the highest frequency of 2.2Ghz, but this may make the product unstable.
What do I need to do to check the 8K decoding on the rev. A? I’ve simply tried to play 8K using the latest nightly and all I got was a black screen but I don’t know if it is supposed to work this way on the rev. B.
Regarding the 8K decoding not possible on the rev. A… would it be possible due to e.g. missing nodes in the device tree or different configuration of the decoder done in the bootloader or is this the proof that it is actually a different hardware?
As Beelink still claims the hardware is the same and that they can release a firmware that will basically “restore” the rev. A to the rev. B.
