Is it possible to switch over a stick of ram from one laptop to another?

Say, I were planning to upgrade my new laptops RAM. Yet, I had a broken Lenovo y580 (LCD messed up on me) can I salvage the 8gbs ram and switch it over to have 12Gbs of ram, instead of the 4 my newer laptop has to offer? Or would this be dangerous, and unhealthy for my newer laptop. (Sager NP8651)

 

Depends. Mobile Haswell requires DDR3L (1.35V), so if your Y580 has standard voltage (1.5V) DDR3, it won't work in your new laptop.

I have a Y500 and if I recall correctly, Lenovo never shipped their Ivy Bridge laptops with DDR3L, only DDR3, so it most likely will not work. However, you should fire up CPU-Z on the Y580 and check its RAM voltage just to make sure.

 

I'm really hesitant to try. Do you think 4GB is enough to play heavy graphic games? (Specs:
3GB GTX 970M GDDR5, Intel i7 4720hq, 120GB SSD,

 

4GB is NOT enough. Not only that if it's only one stick of RAM it's in single channel and likely hinder performance a bit as well. 8GB is minimum you'll need. Just pony up $30 for 4GB RAM. http://www.amazon.com/Kingston-Technology-1600MHz-PC3-12800-KVR16LS11/dp/B00CQ35GYE

RAM is RAM is RAM. So long as it can run at 1.35V you're golden. Won't hurt to put your 8GB in your new laptop and see if it runs. If it doesn't boot or locks up you know the RAM won't work with it, simple as that.

 

Is that applicable to the Sager Np8651 model?

 

RAM is RAM is RAM... DDR3 is DDR3 is DDR3 even DDR3 (1.5V) not designated as DDR3L a lot of times runs fine at 1.35V.

Just try your 8GB module and be done with it. Now if you only have a single chip of 4GB then you will have to place the chip in the proper location to get dual channel. Easiest way to find out is plug it in, run CPU-z or HWInfo64 and see if RAM says dual channel or single channel. If single channel, then turn off computer and put it in the other slot. The stock RAM is usually under the keyboard, so unless you want to remove the keyboard, it's best to place it under the bottom panel.

 

Holy crap, you're that guy from youtube. But, thanks! Also, is 120GB SSD good enough? (Since the Sager was 1327 with windows 8.1, I'm deciding to buy a rebranded one, from eluctronics. (Not 1TB, but 120GB)

 

Re-read my post above, I added to it, you're just sniping my posts a bit here.
Honestly, don't go cheap with an SSD. Get Crucial or Sandisk or Intel. Crucial is probably your best bet, and also get 256GB if you can swing it because performance in general is better.

 

If I were to NOT get the upgrades, which I will, would the games suffer horrendously? Or would it be unnoticeable?

 

Get 8GB RAM in dual channel minimum (that means two sticks of 4GB). 120GB SSD for your boot drive is better than only having a hard drive if only for boot times and general Windows performance. Honestly you'll kick yourself if you don't get 8GB minimum. 4GB is for netbooks.

 

I'll definitely get it after a week or 2 of owning the laptop. Then when I get paid, I'll get it for sure. Thanks!
