Question What other DDR4 memory is comparable with what I have here?

[ncsercs]

My computer came with 2 sticks of 8GB memory and would like to add 2 sticks of 4GB OR 2 sticks of 8GB. What memory would work with this (does not have to be Samsung)?

Samsung 8GB 1RX8 PC4-2133P DDR4 Desktop M378A1K43BB1-CPB

Thanks!

First we have to know what processor (CPU) is in your PC. Some memory controllers do not like 4 DIMM configurations. If it's an Intel box then it should be okay. AMD, however, may get finicky.

Assuming you can pop two more DIMMS in there no problem, get 2x8GB Samsung anything. Best place to find them would be on eBay. It's nearly impossible to find anyone carrying "naked" DIMMs like that elsewhere. I can't paste eBay links according to forum rules, so let us know what you find. Actually, looking briefly, I was able to find two sticks identical to yours for about $100 shipped.

Also, can you run a program called Thaiphoon Burner on your PC? I am curious if that stuff is really Samsung b-die . . . those may be overclocker's dream chips right there!

edit: that is b-die! Damn, wonder what those babies can do?

Lenovo M900 - Intel i5-6500 - Samsung b-die. Can't overclock CPU or RAM.

Noticed the 2x8GB found on eBay are pricey. May just go with 2x4GB

Hmmm. I think 2x4GB will work. Getting something Lenovo-approved would be ideal, of course. If you are determined to double your RAM capacity, you'll find that 2x8GB isn't going to get much cheaper:

Bear in mind that you will want to run any of those products @ DDR4-2133, and the only stuff that's guaranteed to work in your machine is Samsung RAM off the Lenovo QVL. I would be surprised if most DDR4 wouldn't work at 2133 though.

Just got this off the bay for $45.

 

[DrMrLordX]

That should be functional. Let us know how it goes.

UPDATE: Got the RAM. 1 stick as advertised and worked just fine with 8GB + 8GB + 4GB for a total of 20GB. The other one was incorrect (was 4GB DDR3) Sent both of them back. Still waiting for refund. What a ditz.

DDR3? Damn. That sucks. Kinda makes me wonder if they were trying to scam you there.
