From wiki, Blender need 2GB min, 8GB rec and 16GB rec for prod. To my knowledge, you need same RAM for dual channel. Can't get this since your current RAM already soldered to motherboard. From quick Bing, it may work with same "CAS latency, timings, and voltage" but I'm not sure about this. For best performance make sure it the same "CAS latency, timings, and voltage" anyway. Problem with upgrading RAM is older ram have lower performance than new one. Mixing them make total performance as fast or maybe lower than old spec. So if I am upgrading, I would just get the biggest, compatible RAM as I can get.
He said everything. When it comes to ram same frequency, same capacity and same brand. Don't add random size like 4gb+8gb ram because performance will be lower. Should be 4gbx2 or 8gbx2.
Unless the game requires an intense amount of power from RAM. Then I don't think you'd have to worry about it. I can play most of the games with my just 4gb RAM (free PC mmos, lol) . But if its a game like 'revelation online', then I'd need about 8gb/12gb RAM (because when I was playing it with 4gb RAM, the loading speed went down way too much, besides that graphic it got is too much to load for my pc).
Go for 12gb. Reason? I am currently at 15.2 GB / 15.6 GB. Aka even 16 GB is not enough anymore! Modern programs are ram whores. Just look at your browser's usage, each tab can easily eat up 100mb and some go as high as 500mb
8gb is enough unless you are doing crazy intensive stuff like editing 4k videos. Male sure to install a 64 bit OS though.
Get the 4gb stick and make it 8gb. Also, get a stick with similar speed to the soldered-down memory. It would be a different case if you can put in 2 8gb sticks in there, but since the 4gb stick is soldered down, you should try to get a matching pair. I don't know how your motherboard would behave, but in rare cases, some motherboards would complain if you have two different sticks, and would then refuse to run them in dual-channel.
Keep in mind, if you do not have 64-bit Windows, you will not be able to use beyond 4gb. Do check your windows version.
If your system is 64-bit then no problem if you add more RAM,but if it is a 32-bit it doesn't support more than 4GB
I personally think 4GB is more than enough, but... Well, if you really want more, go for 8GB since people said they being on same size matters. I think you should just save the money though, 2GB has always been enough for me after all... >.>
I am quite lost on how much technology advanced, but is there already a system supporting 12gb fully ? W/o waste of resourcefullnes. Cuz that the system support it doesnt mean it can use the ram at 100% perfomance being it waste to have if you cant use it fully
Not sure what in the world you are talking about. My laptop has 16gb ram and using all of it (though I would have preferred more). 64bit OS support up to I think 256,000 GB of ram. When talking about RAM limitations, DDR3 does 16GB per DIMM (8GB prior to fix in Ivy Bridge). So if laptop has 2 DIMMs, that is 32GB and if its 4 DIMM then 64 GB. I don't remember the maximum of DDR4 but I remember it supports at least 128gb per DIMM making 512GB RAM computers possible.
