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)?
Faster RAM for Houdini or RAM with lower latency?209 3 1
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.
