I think 800MHz. And for you it has stable because you have 933MHz (better frequency version)
-
Can be also next situation:
developers know about this problems and put in new revision 933MHz chip, but it not help.
So -> bad layout.
-
BTW, when I worked with 800MHz 1GB some times I had freezy my PC (mostly when run in chrome 3-5 pages).
After I change frequency PC work very stable with 2GB.
-
So, continue.
crazystick has SEC 843 K4B4G16 46E BCMA.
BCMA mean 933MHz
BCK0 - 800MHz
and if crazystick has crash with 2GB then
1. memory chip can be fake, because 933MHz version just should work very well at 800MHz. 80%
2. bad layout pcb for memory. 15%
3. noisy environment. 5%
Percentage is probability
Value that changed in bl1 is frequency. 666MHz
Original frequency was 800MHz
-
Yes (sometimes with, sometimes without bl1 edit - WTF??)
SUPER!
-
this is strange
-
I have same PCB as Igor, but I need changes also!!!
Without changes I have same problems as you -
I'll try to test this later this week. @Vlado it looks like you have the same chip as @Igor but you needed the edit where he didn't which is odd. On his board the chip was printed SAMSUNG 728.
YES, same as Igor SAMSUNG 728 K4B4G16 46D-BCK0
PCB also same!
-
I have three version:
1. bad layout memory bus
2. noisy environment
3. not a quality Power Supply (noisy, so on). not sure
-
But it is memory problem!
-
Better to write like this: if it not work on your T3+ use this hack.
Because it doesn't depend from chip modification

yes works thanks a lot
i have edited this.: https://www.armbian.com/nanopc-t3-plus/
it depends from memory number
my is .; SEC710 K4B4G16 - the last edition - i bought that on june 2019
K4B4G16 last letter (D,E, ...) after char ?(BCK0)
-
So, it works?
will be good if write here chip model where it run
my is K4B4G1646D-BCK0 (728)
-
Should be

ok i have installed okteta. But which file have I to edit on sd-card?
It not file!!! It data on SD card!
You should open your SD card at HEX editor.
-
It looks like not fast process (with renew img).
So, after you have recorded img on SD card you should change value (01DE1010) at this addres 0x00000268. You can do it with HEX editor.
-
So, for everyone, I wrote Igor about changes. Waiting answer!

Does that change the memory allocation, from 1 to 2gb? Like what I mentioned in my earlier post?
On 7/24/2019 at 9:43 PM, Vlado said:So, NOW it work!!!
Armbian 64 2GB on T3+
Yes, need change bl1, or simple way
After you've written img on SDcard you should change value at address on SDcard
should put 0x00000268 (01DE1010)

Can anybody explaned me in which file on sd-card i should put 0x00000268 (01DE1010)?
Thanks
After you've written img on SDcard you should change value at address on SDcard

Can you write where i should make a change? what does mean in bl1
it also can be changed in img on SDcard (may be faster way) 0x00000268 (01DE1010)

Second board with 933MHz version chip not work with 800MHz.
Situations is stable.
For this CPU max. posible frequency for memory bus is 800MHz. Why FA use 933MHz version chip? Ran out of 800MHz memory IC?
