I can’t see all signs clearly. Can I take a photo in normal quality? Or finally write what kind of chips were used, is it really that difficult?

Has anyone looked into overclocking the SDRAM on R4 ? It seems locked at 3200 from my brief check. Worth digging down the rabbit hole?

Edit: I think it’s near impossible to tweak the timings. Happy to be proved wrong.
