I have a 5930K, Gigabyte SLI MOBO.

OriginPC built the system which they have back for a bad MOBO- warrantee work. When I bought It they said 16 GB System Ram @ 2666 was the most I could have, otherwise more ram would actually make gaming slower due to the processor having to recalculate the extra memory back to the 16 it can handle.

Origin shipped- 16GB @2666.
Intel Site says- up to 64Gb @ 2133
Alienware says- up to 64GB @ 2133.

Did I somehow answer my own question, is Origin right or what's what?? I game 40℅; render, graphics, music, office 60℅.

Thank you

(I'm not meaning to disparage any names here!)

Totally bogus.

There is something called a memory controller in your CPU. This memory controller... controls the memory, haha.

Well, that controller is DUAL CHANNEL, which i'm sure you've heard of. So when you have 4 sticks it doesn't run in quad channel, it runs in 2 dual channels.

Well the argument is that this puts additional load on the CPU as the memory controller has to work twice as hard.

This is pretty much a fallacy. While true - the CPU does technically have to do more work to support both dual channels - it is completely negligible - they are 100% designed and intended to run with 4 sticks of ram without impacting performance.

That said 2x8GB sticks is a sweet spot for performance, so they weren't really steering you...

Never thought of the DIMMs. So it has 8 slots of quad 4.Native is 2133, although all OC'able to 3300. So now I'm really confused. Wouldn't more/faster benefit me in CGI/animation stuffs, without impacting gaming which is more GPU anyway??

Oh shit you have a quad channel mobo. Basically what I said holds true but you have 8 dimms and a 4 dimm controller.

More ram improves your ability to work on a single large task, I'm not an editor of any sort but unless your loading your projects directly into ram manually using software I can't imagine you'd ever actually use it.
