[OmgA]

Not sure if its relevant but there was a new firmware for the am6b with mentions of a DDR

New Firmware For Ugoos AM6 Family

New Firmware for Ugoos AM6 Family from 25.09.24 Android 9 Firmware V.0.5.4n add new ddr chip models support

If I update android firmware will I lose the CE (emmc) install?

[MasterKeyxda]

I am happy to see other models get the arm big.little dtb changes

[OmgA]

Backup via the ceemmc tool and restore after updating firmware

New Firmware For Ugoos AM6 Family

Probably best to use CoreELEC Tool ceemmc -x Use option Make copy of CoreELEC Then Tool again abd remove CoreELEC Now flash away at your leisure

[MasterKeyxda]

I’ll wait for someone else to confirm on this update from ugoos. If someone does update can you run

echo 1 > /sys/class/aml_ddr/mode
cat /sys/class/aml_ddr/freq

Currently in the middle of some other stuff with the box, don’t want to add more variables. My expectations are low, should still see less than 800 MHz.

[OmgA]

Sure on it

[OmgA]

752 Mhz is what I get on my end

[MasterKeyxda]

That’s after the Ugoos new firmware update?

[OmgA]

yes running 0.5.4n

[crazyturk]

Same device tested with two different dtb.

Nice on them advertising ddr 4 with speed of 3700 and the bottleneck it to 800Mhz
Don’t know if we should laugh or cry?

@MasterKeyxda , if I want more people to test on S905x4, should a seperate thread be created?

[crazyturk]

test with old dtb

[MasterKeyxda]

I’d recommend it. That way the title says 905 and catches attention from many more people.

[doppingkoala]

Better than s905x3

CoreELEC:~ # cat /sys/class/aml_ddr/freq
360 MHz

[iMediaPi]

these are the boxes that have that chipset
Homatics Box R Plus / Dune HD R Plus / Rocktek G2 / Nokia 8010
Dune HD Pro Vision 4K
ugoos x4q extra

also if Kinhank allow us to install coreelec on the G1 then that would be awesome with a 25% boost in CPU
you could post in each thread to ask if anyone is interested in testing.
I spammed like 4 different sites to get people to come here and test lol
I meant post! I posted!

[akmarwah03]

Made a thread

S905X4 Device Tree - Performance/Efficiency - Testing Needed

Hey everyone, I recently came across a very insightful post by @MasterKeyxda discussing some performance hiccups with the Ugoos AM6B, related to how the Linux scheduler handles CPU process switching and cache detection. You should check out the original post for more details. Following his work, I ran tests on my S905x4 CPU using his script, and I’d like to share my results here and get more feedback from others.
