Asus B121 slate maximum RAM?

Hello all,
It's at least 3 years that I use win10 64bit on my asus B121.
I changed his SSD to 250GB and now I'm thinking to upgrade his ram from 4GB to ___(?).
I can't find any specification about the max ram limit.
The tech specs state that there is a 1 slot, but it doesn't specify how many ram this slot supports.
Do the B121 has the same limits of EP121?
TIA
Tony

 

Nevermind.
I found the answer here: https://www.memorystock.com/memory/ASUSEeeSlateB121.html
1 slot x 4GB max. .

Yep, that's the limit.

On the bright side, the RAM isn't the worst of what holds you back on the B121/EP121. Having a bigger SSD is already going to give you a performance boost in Photoshop. The truly limiting thing on that model, IMO, is the GPU. The processor and RAM are a bit slow but they chug along. Unfortunately, Intel did not support their hardware well at all, and didn't give us the OpenGL updates we could have had, and then time just outpaced it.

I've seen some serious setups with external GPUs, which could be done if someone wanted to take advantage of the B121/EP121's Wacom EMR and decent screen, but at that point, you're not longer talking about a portable tablet.
