W520 S/N ******** Memory Upgrade

2020-09-14, 20:06 PM

The manual did not give all the information needed for a memory upgrade on the laptop.  It only stated that the machine supports PC3-8500 or PC3-10600 ram.  I am needing the following information:


  1. Does the machine support duel channel/quad channel?
  2. What is the max capacity per memory slot?
  3. What is the max capacity of memory for the machine?
  4. Does the machine support DD3 L variations of ram?


Machine Information:


Model: W520

Type: 4284

S/N: ********



Moderator note: serial number removed to prevent abuse.
