A windows update maxed out my RAM and made my laptop a useless lump of metal. So I was able to (very slowly) do a system restore to an earlier version and now it works again.
I have 6GB of RAM on my laptop right now, a 4GB stick and a 2GB stick. That was stock.
I went to crucial and used their system scanner. I can get an 8GB stick for $40. I figure I can replace the 2GB stick and that’ll give me 12GB (my laptop maxes out at 16GB).
However, with black friday coming up I’m wondering if there will be deals better than what crucial is offering. Problem is I have no idea what specs I need to look for when buying RAM. On crucial the RAM they showed me have the following specs
up to 8GB per slot
DDR3 or DDR3L
PC3-12800 or PC3L-12800
CL=11
unbuffered
1.35V
DDR3-1600
NON-ECC
Here is a compatible stick.
Of those factors, I’m not sure what they all mean or which ones I’d need to take into account. All are 1.35V and CL=11, but some are DDR3 and some are DDR3L. Does everything need to be compatible for it to work (what if I find a black friday stick with a CL of 9).
I’m wondering if it is better to just buy a $40 stick at crucial rather than risk buying a $20 or $25 stick on black friday and having it not work.
Yeah but I already have a 4GB and 2GB stick. If I spend $40 then I have 12GB, I need to spend $80 to get 16GB.
My laptop was bought refurbished and I got it 5 years ago. So I will probably upgrade in the next year or two. So I don’t know if I need 16GB.
It came with 6GB when I bought it, and 6GB has always worked fine up until windows tried to install an update last week and maxed out my RAM (it was consistently running at 96% until I did system restore, now it is at 65%). Going from 6GB to 12GB is half the price of going from 12 to 16.
32-bit Windows computers are stuck with a sub-4GB limit. For 64-bit Windows, the lowest editions of 8.X and 10 support 128GB. It’s Windows 7 64-bit you have to pay attention. It could be as little as 8GB or 16GB for the low end editions. Vista also has odd limits. OTOH, XP 64-bit supports 128GB for all versions. I.e., MS is deliberately crippling some versions.
You need to know what types of memory the motherboard on your laptop supports. In some cases, your laptop manufacturer can provide details on what memory module specs are supported. When in doubt, look at the specs on your existing memory modules, and then choose a memory module with the same specs, but a higher GB capacity.
Relevant specs relating compatibility:
Voltage (1.35V vs 1.50V vs …). You must use the correct voltage memory modules for your motherboard.
CL latency. Smaller numbers are faster and more compatible… A CL9 stick will work in a slot running at CL11; it will just run at slower CL11 speeds. A CL11 stick may generate errors in a memory slot running at CL9.
MHz (-1600, -2133, etc…). Bigger numbers are faster and more compatible. A faster stick will run is a slower slot, it will just run at a slower speed. A slower stick may generate errors if put in a faster memory slot.
Single-channel versus dual-channel memory sockets in your laptop. If your laptop memory sockets support dual channel capabilities, you should buy two of the same module as you will get performance gains. If your laptop memory slots are single-channel only, then you can install two different modules, since the two sockets will operate independently. If you install two different sticks in a dual-channel-capable memory slots, that will still work, but you will lose the dual-channel benefit and the system with downshift to single-channel operations.
