I bought an Inspiron 15 AMD model. Add this 8GB memory to 16GB. Add this SDD to 512GB + 1TB. Replace the WiFi module from WiFi5 to WiFi6. The latest AX201 etc. can not be used with AMD CPU. The AC adapter uses a PD charger. First, open the back cover. These two screws cannot be removed, so leave them as they are. I will remove it with the ceramic knife I bought at Daiso. First, for safety, remove the battery. Insert DDR4 memory in an empty slot. Remove the 2230 SSD here, Attach it here. Move the SSD mounting bracket. 2280 SSDs can be installed. Remove the WiFi module. Carefully disconnect the antenna wire. Attach the antenna wire to Intel AX200 module. Connect the battery and you're done. Test the memory with MemTest86. It recognizes 16GB and runs at 3200MHz. It was completed successfully. It took 3 hours and 36 minutes. The SSD you added is recognized as the D drive. Also measure the read / write speed. The replaced WiFi module is an unknown device. Install the two pre-downloaded drivers. This was installed with [Normal]. Restart. BlueTooth version has changed from 5.0 to 5.2. WiFi has changed from 11ac to 11ax. Transfer the file to NAS and see if it's faster. Download is about 40% faster. Upload is almost the same. I think the performance of the router (TP-Link AX1800) currently in use is not good. Finally, measure performance with a game (GTA 5) benchmark. The reason why the frame rate has more than doubled, The memory has changed from single channel to dual channel.
