Question Looking to max out RAM

[silverfang77]

My PC is a PowerSpec G418: ASRock Fatal1ty Z170 Gaming K6 ATX LGA1151 Motherboard, G. Skill 16GB DDR4-3200 RAM.

The board can max out at 64 GB RAM. Would I be best served getting this: https://www.newegg.com/corsair-64gb...gb_ddr4-_-20-236-586-_-Product&quicklink=true
CORSAIR Vengeance LPX 64GB (2 x 32GB) 288-Pin DDR4 SDRAM DDR4 3200 (PC4 25600) Desktop Memory Model CMK64GX4M2E3200C16,

VL is correct regarding the commit charge.

Commit charge is the virtual memory (physical+pagefile) what system guarantees that will be available to programs/processes . It's not physical memory in use.

Sysinternal got a RAMMap utility that shows how much physical memory is in use.

RAMMap - Sysinternals

An advanced physical memory analysis utility that presents usage information in several ways on its different tabs.

Humm, I guess I'll give this a try. Always thought the second number on commit charge is the ram + pagefile size and if you hit that you hit a wall unless your pagefile is set to auto.

That's true too. But that doesn't invalidate what I said.

Basically, that second number on commit charge, is the current ceiling on the commit charge, that it can reach. That's the current total pageable physical RAM + pagefile that can be allocated. If you have auto-expanding pagefile set, the kernel will "grow" the pagefile once the ceiling is close to being reached.

Nifty tip, on "auto" pagefile, the most that it can grow to, at least in Win7 64-bit, is 3X physical RAM, thus giving you, at most, 4X Physical RAM size in virtual memory capacity. (1X Physical RAM, plus 3X Physical RAM capacity in pagefile.)
