Faster RAM for Houdini or RAM with lower latency?

Hello.

It is my understanding that you need 32 GB RAM to “learn” Houdini (from my experience, 16 GB RAM cuts it waaay too close when compositing heightfield textures), and at least 64 GB to simulate oceans and other small scale stuff (for production).

But what about the RAM speed? Is faster RAM preferred (e.g. 3000 MHz, 3200 MHz) or lower latency ones (e.g. CL13, CL12)?

Eh, it's more about the amount than the speed. You can control the speed of the simulation by controlling the resolution.

At a guess less latency is preferred for non-opencl non-flat memory work and faster speeds for opencl work. Really need to test that hypnosis in consideration of other computer subsystems, i.e. CPU, bios etc

The majority of the latency is due to the memory controller on the cpu. Traditionally Intel CPUs have better latency than AMD. More DIMM modules will generally add more latency than an equivalent amount of memory using fewer sticks (eg, 8*8 vs 4*16), though you'll want to take advantage of dual and quad channel memory wherever possible for increased bandwidth.
