Thinkpad T520 4240-6BG memory, SSD upgrade

My laptop model has mSATA slot and 2.5 inch SATA drive bay. I am not able to identify the SATA version for either in the manual. A hardware test, and the existing hard drive manuel both shows the current SATA version is 3.0 Gbps. It contradicts what the forum common response on that T520 has a SATA III support. Will some one points out a reference on official documentation.

The manual says the laptop support 8 GB. My CPU is Intel Core i5-2450M, shows my processor supports maximum 16 GB. How much maximum RAM capacity does this laptop supoort? The manual states "Use either a PC3-8500 or a PC3-10600 DDR3 synchronous DRAM unbuffered SO-DIMM supported by your computer" If I want to search for compatible memory and memory comparision, review what termsn shall I google for?

Welcome to the forum! 


The mSata slot is SATA-II, while the 2.5 bay drive is SATA-III.


A total of 16GB (2x8GB) is supported. You can buy DDR3-8500 or DDR3-10600 modules, I had trouble with my T520 to recognize some DDR3-12800 RAM, but I recall reading that other users managed to get such RAM working. 


I would generally recommend to stick to well known brand names and avoid no-name RAM from eBay and similar shops, I'd also say to avoid the "Value RAM" line from Kingston and the "Value Select" line from Corsair.


I don't have a specific link with the specs though... Smiley Sad
