Lenovo Ideapad Flex 6 (14") - is this RAM compatible?

2018-10-01, 1:44 AM

I'm looking to see if anyone could help me out. I've done a LOT of researching and I think I've found a new RAM card that will be a compatible upgrade for my new laptop. However, can anyone confirm that this RAM:

 

https://www.amazon.com/Corsair-Vengeance-SODIMM-1x16GB-Systems/dp/B077S17RPZ

 

(More specs on the card can also be found at Newegg)

 

would be compatible with the laptop listed in the subject line (Model: 81EM000NUS)?

 

I'm trying to get upgraded soon but don't want to spend the money and wait for it to find it doesn't work.

 

Thanks!

Solved! See the solution

Per the specifications page of the psref for that model, that memory appears to be the correct type for your laptop.   

 

I personally have had better luck with memory from Crucial/Micron on Lenovo systems, but that does not mean that Corsair is not also a good choice.

 

 

Cheers,

Thank you!

 

Another question for you then...I had been highly considering a Crucial chip, but finally decided on something else because I was looking for something with less latency than what I was finding with Crucial. Do you know of any chips from Crucial with similar specs (DDR4-2400 SODIMM, 16 GB, Dual Ranked, etc) but with a smaller CL than 17? Or does it really matter?

 

Also, I was wondering, is it totally crazy for me to run software that might demand a greater than average RAM if I'm only running with an i3 processor (ie. AutoCAD or SOLIDWORKS)?

Don't mean to be bothersome with multiple replies. But I've read a lot of good things about both Crucial and Kingston. So I was wondering if you think I'd have good luck with this chip or if I should stick with getting a Crucial for Lenovo?

CAS latency is not always an accurate measure of the speed of the RAM itself (true latency) and I don't really think that you will notice a nanosecond here or there on your system.

 

There are 3 major chip DRAM chip manufacturers out there Samsung, Hynix and (Micron(Crucial.     RAM module manufacturers like Corsair and Kingston etc. do not make their own DRAM, so they buy their DRAM from the various vendors with the best price, which means the actual DRAM can vary from purchase to purchase, while Crucial, being the retail arm of Micron does, will always use Micron DRAM, so you now you are getting the same quality every time, which I why I tend to gravitate towards Crucial.

 

That said, there is nothing wrong with Samsung or Hynix DRAM, but there are also some other small manufacturers out there too, such as Nanya, Winbond and Elpida, whose RAM I just try to steer away from, so with what ever RAM to do chose to buy, I would ask what DRAM modules they use, and try to stick with the Big three if you can.

 

Cheers,

Okay, one last question then. Would it be better for me to get a RAM stick with a higher speed or with lower latency? Or should I try to find a combination of both?

I guess I'm a little stuck on the fact that my current 4 GB RAM is running with 2666MHz and 15 CAS CL, and I'm trying to keep my upgrade similar in performance.

Also, I'm not completely certain I follow your logic about manufacturers. As far as I've understood it, Kingston is an independent chip manufacturer while Samsung rarely sells chips to the public with their own name on it. They commonly sell their chips to other companies

Kingston assembles the RAM modules, but it sources the most of the DRAM chips it uses from several manufacturers, but they are all stamped Kingston (I have heard that Kingston may make some itself, but not much).    I am not saying that Kingston or Corsair make bad RAM modules, but Lenovo systems in my experience work well with Crucial and Samsung Ram  

 

You can find Samsung and Hynix branded RAM for sale on the Internet, but you are correct in that, in the States at least, it is harder to find under their own brand name.

 

I buy a lot of RAM, so my logic is that I do not want to deal with Ebay or Amazon stores etc., and prefer to buy from a known vendor like Crucial because their RAM I found works well,and they have excellent support should there be a problem.     

 

For you, you might want to go a different route.

Hi,

I have an Ideapad 320, 

 

On this laptop, it had built-in RAM 2133MHZ, the vendor sold me upgradeable RAM of 2666MHZ, so I had 2 sticks of 4GB of RAM,

with two different MHZ,  i experienced so many problems, system freeze, intermittent restarts.. It was awful....

 

Since i bought new RAM with the same MHZ, i have had zero problems..

My advice would be, buy the RAM with the same MHZ.....
