Hi,

When im playing on any server, such as Hypixel or Mc-Central, when the memory fills up and resets, the game momentarily freezes for a split second.

Edit - It happens in a single player world too (fresh world, just loaded)

I have played Minecraft for many years, this never used to happen, so im confused as to why it started to happen now.  I updated my system recently, new motherboard, graphics card and cpu and reinstalled windows 10 (latest version). 

What have I done so far .. I have ran stress tests/memory tests for many hours, such as intel burn test (for cpu), memtest86 (for ram), and unique heaven (for gaming) and they all pass.  I have switched the ram for another set of ram, different manufacturer, but the stuttering persists.  I have also reinstalled Minecraft, to no avail.  I also tried running a program called Intelligent memory stanby list cleaner, which has not helped.

Each time the Mem : resets, the screen freezes, for a split second.
