Update: according to a forum, the devkit switch has a 64GB chip, and people have already done mods to read and write the chip outside of the switch.
The only problem that might arise is the Samsung chip has 2bit MLC (Toshiba doesn't give that spec) on their 32GB chip in the Gamers Nexus' Switch, their largest 2bit MLC chip is 128GB, they offer a 256GB chip but that has a 3bit MLC.
There's hope for storage mods, and there's hopes for a larger storage switch.
It looks like different Switches use different eMMC chips.
Yours had a Toshiba THGBMHG8C2LBAIL.
Gamer Nexus' Switch had a Samsung KLMBG2JENB-B041; seen here https://youtu.be/obz5tE1mdV0?t=9m40s
Samsung's is .2mm thicker at 1mm thick.
I'd like to see someone do a swap with a larger sized chip.
SoC > thermal paste > the shield/cover around the SoC and nearby components > copper shim > thermal paste > pad >mounting bracket and copper pipe, with what looks to be a layer of material between the bracket and heatpipe; also can't tell if the bracket is brazed to the sides of the heat pipe, or if it's under the heat pipe > thermal paste > backplate.
Also keep in mind that the SoC has an internal heat spreader, with is either soldered or pasted to the chip itself. So there's even more interfaces.
The 'pad' on the heat pipe can be seen on Gamer Nexus' video here: https://youtu.be/obz5tE1mdV0?t=10m46s
I also wonder what effects that shield/cover on the SoC is going to have on the DRAM it covers when it heats up.
So there's 10+ parts on top of the silicon including the IHS and it's solder/paste, 9 if the mounting bracket is brazed to the sides of the heat pipe, 10 if the heat pipe is on top of the bracket. Keep in mind that a standard computer only has 4-5 layers on top of the silicon.
Also step 13, third picture, is the Switch's side of it. The contacts are on the underside of the rail.
Thunderbolt is an Intel proprietary external PCIe port. Nvidia would need to develop their own proprietary external PCIe solution.
The Switch would also need extra hardware for this, mainly a couple more ICs.
But it could work since USB type C allows an extra set of data lanes to be used at a non-USB port, this is how the Switch outputs a MyDP signal (which the dock has a MyDP-HDMI converter). But currently, the Switch doesn't have supporting hardware for an external/hybrid gpu setup.
Megachips STDP2550 Mobility DisplayPort (MyDP) to HDMI Converter, part of the dock. You need a MyDP to HDMI converter, as the Switch puts out DP and not HDMI.
Just a question.. Where's the wifi card? And can I update it to the new wifi ac? Id love to have gigabit speeds on my Sony.
