Z500 - Ranks Compatibility in RAM Memory

2018-02-02, 14:59 PM

My Device is : Ideapad Z500 Corei7

I upgraded my RAM From 6GB(2+4) to 12GB(8+4) and now there's another question for me
The RAM I currently have is a 4GB Remaxel and a 8GB Samsung with frequency and bus and Voltage the same delay, but with different ranks.
This means that the 4GB RAM has a Rank 1, but RAM 8 has Rank 2
I did an investigation and found that Rank 1 was better than Rank 2, but now that they are installed together, will there be a problem? Or would it be better to have the same rank? is there any touchable difference ?

 

Mod's Edit: System model added to the front of Subject line to improve visibility / clarity.

 

Solved! See the solution

What you have installed is just fine. Ranks will not show any difference that you could see.

Was your new 8GB stick not Crucial?

Hi AminBhr,

 

Greetings.

 

In addition, it is preferred to have similar ranks with consumer laptops but on the same note difference in ranks does not really have significant impact in performance and same with long term use as used by many fellow users that have mixed ranks in teir upgrades.

 

To explain more of the details, here is a good discussion to review.

 

Hope this also helps.

 

Regards

The Samsung is listed in your HMM as Lenovo tested memory.

It is also dual voltage dual ranks.

Could you state the part number of your 4GB stick or provide a CPUZ screenshot?

I just wanted to look up vendor specs of this memory.

The OEM 4 GB Ramaxel:

http://ramaxel.com/product/DOWN/book/RMT3160ED58E9W-1600.pdf

Dual rank, single voltage (1.5v). ..E9W is only 1 voltage.

 

Your 4GB Ramaxel: 

http://www.ramaxel.com/product/DOWN/book/RMT3170EB68F9W-1600.pdf

single rank, dual voltage. ..F9W is dual voltage. 

Read the decode part number on bottom of web page.  The top of the webpage states it is 1.35V.

 

Glad all is working.
