Hardware Hacking Switch OLED 256gb NAND upgrade

[ratgoul]

OLED is a 10 layer board. I don't even think you'll manage to remove an eMMC with just hot air.

looking to buy a preheating plate, do you have any suggestions?
Thinking about the UYUE 946C on aliexpress

400mbps wtf?
I thought the switch was limited to something like 40 or maximum 50mbps, or that's because the old eMMC, and installing a new one get new speeds ?

This is average speed for switch emmc, samsung may even be faster
in comparaison with Kingston 256gb :

The switch does get 400MB/s on basically every nand unless something isn't connected right. My old 2016 switch had 400MB/s on nand

I see your video on youtube



I'm very impressed

But i just don't understand one thing:
Why did you upgrade the RAM? Is there any benefit to that? Because from what I know, games are written to only take advantage of 4GB, correct?

More RAM can be used by Linux and maybe Android

Plus some games can actually use the extra space although they're few and far between

Mainly for overclocking performance, if you compare it with the previous AB-MGCL that was on this switch, there is a significant difference ~2500Mhz vs ~3200Mhz + tight timings on L4T
On HOS it depend on games, but most don't use it

The extra MHz is interesting (about 30% more bandwidth). Mine OLED reaches 2500 MHz too.

Decided to join in and install a SanDisk SDINADF4 128G. Works great and glitches fast unlike the Toshiba chip it replaced.
Thankyou to all that have contributed guides and info on the various threads about emmc upgrades.

First what were your timings second how did you edit the value amounts in sysclk-oc third how did you make some games use 8gb
