 +====  Upgrade RAM 32MB ====  
 + 
 +You can upgrade RAM by desoldering SDRAM chip and soldering chip with  32 MB. It is required to have  4M x 16bit x 4 (otherwise you would need to recompile bootloader) taken from old laptop memory PC133 SO-DIMM. It can be by example: 
 + 
 +  * Winbond W9825G6JH-6 
 +  * Samsung K4S561632C-TC 
 +  * Samsung K4S561632E 
 +  * Micron  mT48LC16m16A2  
 +  * EtronTech EM63A165 
 +  * ESMT M12L2561616A
-Serial port settings: 57600n8+ According to Boot strapping description pins:  
 +  * EPHY_LED3_N  
 +  * EPHY_LDE2_N 
 + are used to determine SDRAM size: 
 +  * 0,0: 2 MB/8 MB (default)  
 +  * 0,1: 8 MB/16 MB  
 +  * 1,0: 16 MB/32 MB, 32 MB*2  
 +  * 1,1: 32 MB  
 + In order to set memory to 32MB you have to add 4.7k resistor (or just shorten)[[http://my-embedded.blogspot.ru/2013/12/mini-4g-router-rt5350f.html|Mini USB Portable 3G/4G router - rt5350f]]
