Chronos User Discussion / Re: Procedure for RAM upgrade
« on: November 17, 2022, 10:23:53 AM »
Bingo !
I have now a Chronos 1.4C 24Gb up and running.  ;D ;D

Thank you Nikon1 for the the idea to reflash the SD card.
I was a bit skeptical about this proposal because the camera was booting correctly with no RAM installed  but was hanging up each time a RAM module was there with the KT logo looping forever. So my initial thought was that the firmware was OK... But if you ask for advices and you don't follow them what is the logic ?
My original 8 Gb module was intalled at the initial position, I flashed the SD card and ... it worked !!! Ouff...

Then I tried my 16 Gb module alone > OK
And I tried both modules together  16 + 8 > OK  ;D
So I can confirm that with FW 0.7.0 the 24Gb combination is working. I shot a short video to cross check just in case. And I will post something if I discover a problem in the future.

I can also confirm that  this 16Gb module works: Micron 16GB DDR3 PC3-12800 SODIMM Micron MT16KTF2G64HZ-1G6A1
I do understand the recommandation to use modules that were already tested by the community and thank you for the pictures on the various posts but unfortunately none of them were available here (btw I am in France). Then I had to find another solution. It is true that RAM modules  are not expensive but finding 16Gb  in one unique module is an issue. But these Micron modules are rather cheap and easy to find on the bay therefore I decided to give them a try .
I will add a picture as it can help somebody else.

One recommandation for those who want to  experience the RAM upgrade. Remove the battery and put it aside. Then  test your camera with the A/C adapter. I am saying that because during my tests I was using the battery and few times I started to open the camera and disassemble it with the battery inside. Mainly because I was obsessed about my trials that I forgot to remove it. This is not a good idea to disassemble anything with a battery plugged, you can damage your device. Putting the battery aside and far prevented me to do this.
The second thing is to take care of how your are dressed. If you are wearing too much synthetic clothes you have the risk to send an electrostatic discharge  (ESD) to your camera and you can ruin it. I changed my jacket for these operations as I knew this jacket could charge/discharge easily...

That's it and many thanks again Nikon 1 , you saved my day !!

Chronos User Discussion / Procedure for RAM upgrade

Hello Everyone,

I just bought a pre-owned Chronos 1.4C 8 Gb camera as I want to explore what can be done by this amazing thing. It is really exciting and I was impressed by all the videos on YouTube. This camera is close to be brand new and was used only a couple of times (lucky me)
When I received my camera the FW version was 0.3.x  and as usual I upgraded it to the latest FW version 0.7.x, The process was easy and smooth. Well documented and I read many of your posts on this forum. Thank you all for that.

Then I decided to go one step further and to upgrade the RAM. I read carefully the post explaining the kind of RAM that is required and I found a Micron 16GB DDR3 PC3-12800 SODIMM Micron MT16KTF2G64HZ-1G6A1 module that should meet the requirements.
I installed it in addition to the 8GB module and started the camera. The camera booted correctly but was indicating 0 Gb, I found that I didn't inserted the two modules correctly. I re-opened the camera, re-engaged the modules, then the camera was displying the KT logo, looping forever .. I tried all combinations possible and went back to the initial configuration with my original 8 Gb module. No way, it is still showing the KT logo forever  :'(.  I tried to charge the battery 100% SoC , I tried with the A/C adapter alone with/without battery. I though I damaged the main PCBA therefore I removed all the RAM modules and the camera could boot completely showing "0Gb" so I was a bit releived. I am currently running out of ideas. I may have damaged the 8Gb module but usually they are robust and I am a careful guy. I will buy new ones but before that any idea or recommendation would be welcomed. I read many posts but I may have missed some of them.
Sorry for this rather long first post  :o
