-===== RAM ===== +==== RAM ==== 
-WHR-G300N V2 comes with 32M RAM which is DDR 16bit. The native U-boot can recognize 64M RAM and pass the info to kernel. Unfortunately, the kernel rejected the 64M info and force itself running with 32M RAM. After flashing with OpenWRT, 64M RAM can be fully utilized.   +WHR-G300N V2 comes with 32M RAM which is DDR 16bit. The native U-boot can recognize 64M RAM and pass the info to kernel.

 ==== Flash ==== ==== Flash ====
 WHR-G300N V2 has 4M flash which is too small for DIY. After the research, I found it can support 8M and 16M flash with modified TP-Link 841N V5 Bootloader.  WHR-G300N V2 has 4M flash which is too small for DIY.
