  What is your proposed ram able to do that your current ram can't? ie. what are you trying to achieve with the change?

    I do a bit of cad, bit of video and gaming. I just wanted something that would modernize the PC to its potential.

  First before spending money - what ICs are on your current sticks & can you overclock them?

  Or are you doing legit production workloads (perhaps with that amount of RAM) so can't afford instability/the down time to dial in an overclock?

  Every cheapo OEM without heat spreaders or "gaming" with heat spreaders set of sticks I've played with, albeit generally 2x8 or even just 2x4 sticks, has been able to hit 3200c16 at absolute worst, which would be a decent help in your situation if you can do it with those higher density dual rank sticks (or do you have 4x16 which would be even worse for OCing than 2x32? 4 dual rank would be quad rank after all, poor IMC)

  Edit: what oscargamer said is relevant too - most tasks that need that quantity of RAM aren't as fussy about the speed and latency, so is definitely your bottleneck?

    I have 4x16 currently. I use a mac now for work so this PC is mainly for personal use although a bit of gaming cad and editing. I have my RAM Oc to 2666 at the moment. Current ram is 15,15,15,35. http://www.gskill.com/product/165/184/1535941837/F4-2400C15D…

      what's your GPU and monitor?

      If you aren't doing super high refresh (like with a 1080p 240hz monitor) then the CPU probably isn't the bottleneck for gaming anyway.

      Video editing would want quantity of RAM before speed, and you'd likely be GPU encoding so the CPU's speed being slowed a little by the RAM would likely not matter (if you're software encoding you might get a big jump going to 3200 or faster though)

      Don't know enough about CAD to know where the bottlenecks would be, but I'd imagine it'd be similar to video editing more so than gaming

      Regarding your current RAM, have you used thaiphoon burner to read the info out of the sticks? You could be lucky and have double sided/dual rank B die or something in there being 4x16 - if you blast that with 1.5v and point a fan at them you could probably clock it way higher.

      Ryzen memory calc can be a rough guide but depending on your sticks it can be terrible too (eg: in my experience it is useless for Micron Rev E but ok/good for B-Die). I dial all my overclocks in manually now using this guide to jog my very broken human memory, with AIDA for bandwidth/latency checks to make sure I'm not going backwards and old slow HCI memtest to check it cause I paid for the licence damn it I'm going to get my money's worth (I go to 2000% overnight to make sure, had some really late errors pop up with Rev E that caused real world errors after a few days uptime even though it was "clear" up to 400% or even 1000%)

      Be aware all the testing and retesting for overclocking, especially with RAM having so many variables due to all the timings, means if you don't enjoy it it can easily be "cheaper" to just buy the expensive new sticks and be done with it, depending on how you value your time it doesn't take long to hit the ~$500 of time spent to have bought two 32GB kits instead.

  There's no good deals at the moment because there is a shortage of … well, everything.

  Quick search shows there's a 32GB Kit 3600mhz (CL18-22-22-42) for $239 + free delivery at CentreCom. Timing is a little loose but you can use 1usmus Ryzen DRAM calculator to tighten it.
