It is safe to connect directly gnd to gpi0 and 3.3v to ch_pd ? I see some diagram use 10k resistor

Installed ESP-Link on NodeMCU v3. Along with this, I updated the bootloader. Initially, I did not know how much memory the module has. When trying to upload files (tried according to the instructions, at different addresses depending on the size of the memory), the firmware was successfully installed only when it was uploaded to the addresses, taking into account that the module has a memory of 512 KB. Question - is it possible that my NodeMCU has an ESP8266 installed with a memory size of 512 kb? After all, all the descriptions say that there should be 4 MB. After a reboot, the monitor now displays: SPI Flash Size & Map: 4Mbit(256KB+256KB). In the "Detected Info" window of the ESP8266 Download tool, it writes QUAD; 32 Mbit.
I could not resist and opened the screen cover of the module, the memory there is XM25QH32BHIG, i.e. for 4 megabytes. The question is the same that I already asked - why, when flashing this module through the Esp8266 download tools program, is it successfully flashed only when you register start addresses for recording that correspond to the module's memory size of 512 kilobytes? If I specify addresses for a module with a memory of 4 MB, then after the firmware the module goes into a looped reboot
