Lenovo G505 memory upgrade

Hi everyone,


This is my first time upgrading RAM in a computer/laptop so please bear with me as I try to figure this out.  In a nutshell, I'm just trying to figure out of the RAM I purchased for my laptop is compatible with the stock RAM already installed.


System Specs:

Lenovo G505, running Windows 8 64-bit

CPU: AMD E1 2100 APU with Radeon HD Graphics (1.00 GHz)

Stock RAM (slot 0): DDR3-665 (1330) MHz , Single Channel

(Note: above info was pulled from MaxxMem)


I purchased the following 4 gig stick from Crucial:


The following link is a crucial system scan AFTER I installed the above linked memory:


My question is... is there any reason why my laptop seemed slower when I first booted it with the new RAM?  After a day of use it seems to be ok, but not necessarily much faster.  Does the RAM I purchased need to match the DDR3 PC3-12800 of the stock RAM?  My apologies if I included more information than necessary... thanks in advance.

Hi destrad3,


Thanks for your question.


I have had a look in to this for you and I can confirm that the memory you have ordered is guaranteed to be compatible with your system.  The system scanner also shows the full 8GB as being installed and picked up by the system.


When you install memory the first boot up can sometimes take longer than usual.  The reason for this is that your BIOS detects a hardware change and is updating that you now have new memory modules installed.  You will notice the difference in performance form your system when you have more programs open at once.


RAM allows you to have more active programs open without your system having to struggle or slow down to use them.  If you're system is not running a lot of programs at once you may not notice it right away through everyday use. 


If you do have any other questions at all, please don't hesitate to ask and I would be more than happy to help.
