Sure, makes zen sense to me. You are overburdening the processor with the extra memory, which needs alot of housekeeping and searching.

I suspect there is an optimum memory size for each motherboard-cpu combo out there.

A similar problem used to occur in older pentium-era computers back in the day. A motherboard may say it could handle 4 gig ram, but it ran faster with 1 gig.

I think of it as a chef at a worktable. The chef can work faster with a small table, where everything is within arms reach.... and is definitely slowed down by a giant worktable.... the table (ram size) needs to be just the right size for the intended job.
