should I use triple-channel RAM with quad-core CPU?

About 5 years ago, I was working in a geophysical processing centre. This involves lots of number crunching, and also lots of data shifting. They were always trying out Intel versus AMD, different chipsets and memory et cetera. There were both linux clusters and graphics workstations that had to be the fastest. Now I recall one of the IT testers saying for a dual-core CPU, you needed dual-channel RAM, otherwise the memory bandwidth would drag you down. Nowadays, we have 4,6, 8 cores. So then should triple-channel RAM be mandatory? More memory bandwidth is never a bad thing, nor is more memory, which is possible with boards having extra RAM slots for the channel. Is it going to make a huge or even noticeable difference? No. Will it make a *measurable* difference? Probably. I would call it "nice to have" rather than "mandatory." |
