Hi!
I want to upgrade my Chuwi Hi13 Q64G45170902164 with second RAM chip “ELPIDA EDFB164A1MA-GD-F 4Gb”. I see free place on motherboard for that. I found the same RAM chip in AliExpress as is already installed in Hi13.
In my service said that they need not only second RAM chip but also “RAM configuration straps”. This is information how to configure special resistors which support compatibility with existing RAM and central processor.
See example of “RAM configuration straps” for MacBook and my motherboard.
Hi!
That’s me again)
Are there news about straps configuration for RAM expanding?
I realise that that Chuwi Hi13 is quite old device and documentation may not be available now.
Try to ask tech support about RAM configuration on mainboard using more generalized key words: "schemas for motherboards with ELPIDA EDFB164A1MA-GD-F 4Gb RAM chip” and “Apollo Lake SoC tablet main board scheme”.
I think that our domestic soldering service specialists could understand it and find solution.
