What does "maximum memory" mean?

2017-04-20, 2:02 AM

Most computer specs state a maximum amount of memory the computer can support. For example, the specs for my ThinkPad T510 say "Supports up to 8GB maximum memory."

 

What does this number mean? Is there actually a limit to the amount of memory a given computer can support, or is it simply the number of available slots multiplied by the largest SO-DIMM size available when the specs were written?

 

Now that 8 GB SO-DIMMs are available, will my T510's two slots support 16 GB?

I have tried 8GB DIMMs in T410/T510 machines and they just won't work.  You can use 2X4GB, but even 1X8GB (2nd slot empty) will not work.

 

This is similar to limitations on newer machines.  There are now 16GB DDR3l DIMMs out.  They will work in a T450 but not in a T440.  It is a limitation of the Intel chipset.

Hi Orthoducks,

 

Welcome to Lenovo Community! And happy to have you here.

 

As I understand that you have query regarding what's the meaning of Max memory in specification page of Lenovo product.

Basically 8GB max means the maximum amount of memory can be expanded within a system. In your case system has to slots so it can be expanded like 4GBx2 slots= 8GB. 

 

I hope the above information helped you.

Please feel free to post in Lenovo Community Forums if you have any further queries!

 
Regards,
Prabhansh

It could be either or both. There's a limit to maximum amount of memory that a chip set can address. Sometimes that limit is higher than the maximum amount of memory you can install.

 

In addition, Lenovo's specifications state the maximum amount of memory that they tested a system with. Sometimes the chip set can handle more but there aren't any DIMMs available that have that much memory. For example, when the T61/X61 came out the largest DIMMs were 2GB. Lenovo's specs said the maximum RAM was 2x 2GB = 4GB. However when 4GB DIMMs became available people discovered that these systems could handle 2x 4GB = 8GB.

 


 Now that 8 GB SO-DIMMs are available, will my T510's two slots support 16 GB?


According to Dr. Google, no. See e.g. Install 16GB RAM on T510 and Maximum RAM? T510-4313.

Agree with both Hausman & Richk and this system can only supports max upto 8GB which can be splitted into 4GBx2 slots possibly due to chipset limitation.
