Chronos User Discussion / Re: 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 

Experiment with different combinations of RAM modules in different slots. You can try using only the new 16GB module or try different arrangements with the original 8GB module. This can help identify if there is an issue with a specific module or slot.
