No. I still don't really get it. I know memory is the buffer to the cpu, so you are able to feed the cpu faster. 8 logical cores doesn't seem to need that extra speed much. The benchmark showed pretty minimal increases in most aspects. So high loaded cpu's could use a bit faster ram. I could see a 64 core server setup needing fast ram.
