Sounds like a good news...

ok, thanks to Norbert's testing we can see I have an answer for RAM and CPU, I just need to work out the GPU throttle. Thanks Norbert!

Norbert6's device has a leakage level of 4000 and is stable up to 1.7 GHz

Would be great to build up a picture of stability vs leakage level as I could then write code to auto-set frequencies to match

Sorry, only have one device

Why do you think 1.6ghz failed? After a short time the screen "freaks out" and I had to cut power connection to reboot...

The 1.6 GHz build used reduced voltage to see it that made more/less stable.

I think we have an answer!

Present for Norbert > 1.7 GHz kernel with 720 DDR

d33, sounds very good, I can't wait until I will be home and test, but can you build this in 720p version?

Just a little concern...

If my device do not start with 1.8GHz kernel, do I have to reset it ? Or that's will be OK with romflashtool ?

Just reflash a known working kernel using "LOADER" mode

If you are not comfortable doing this then I recommend not. Play safe!

[mikele]

"loader mode" ? you mean like I do for installing other kernel with romflashtool and kernel selected only ?

Why?

The desktop SHOULD just rescale. My kernel has Rockchip's faulty EDID fixed so it should read your TVs capability. So on my TV it presents a 1920x1080 desktop to my TV at 1080p60. On a TV that can 'only' do 720P60 (50) then it should scale the desktop to the HDMI.

If it doesn't then let me know and I'll build more but it shouldn't be necessary. Certainly not for this quick test.

OK I will test it.

1.7GHz no boot just googleTV and black down so I hink its useless to try 1.8GHz right ?

What about 1.5 GHz?

Can you post your DMESG for the standard kernel if even this doesn't work and we can add your result/leakage level to the list.

Ta!

for now I use your 1.6GHz 1080p for my gk525 RK3188-T and thats run like charm so its useless to try 1.5 right ? My dongle stay cold and run perfectly at 1.6GHz

Whilst I'm pleased for you this is about testing and posting results

Please post the DMESG from the 1.6 build. As a reward I might build you a 1.6 override with faster RAM
