What is the Optimal Virtual Memory Size

What is the Optimal Virtual Memory Size
The windows page file. Windows uses a page file to store data that can’t be held by your computer’s random-access memory when it fills up. While you can tweak the page file settings, Windows 10 and Windows 11 can manage the page file just fine on their own. windows 11 optimize performance using virtual memory.

Do you use virtual memory? let me know in comments below.

I had to adjust my paging file due to recieving "Out of Memory" errors while playing Vermintide. My PC has 16Gb (DDR4) of physical ram, and 1Gb of vram on an integrated GPU but was encountering out of memory and other errors while playing graphically intensive/ memory demanding games. I increased my page file exactly as he described doing so in this video (according to Microsoft's reccomendation) prior to this video coming out, and have not received any errors since while playing "demanding" games. Good video, as it was informative and helped verify that I did things correctly.

i think the main pro from setting this up manually is that windows works with way to small lows, and we fix this by making a good mini such as the one u recommend using. making the transitions smother and less reactive, causing less stutters.

Thanks Brian.
I usually take a glance at these setting, but then simply let Windows handle the page file.

[kingswimmer]

Thank you so much for clarifying this concept!

I find leaving the page file at its default and monitoring its actual size through the day. If it grows then that should be the new start size.
Moving the file to another disk might help (a little) on non SSD drives but removing the page file from the C drive will mean you won’t get a crashdump file in case of a crash.

[chris-fcim]

Letting the system take care of that by itself is optimal, you can also create a second paging file in the D or data drive as well as download and play most games from the D drive.

finally someone debunks this nonsense every optimization channel keeps posting. you sound like michael caine. brilliant!

Love your work - thanks for looking after us all !

I have my page file at 2 times the size. I have 24 GB so I have the page file at Initial 24000 and Maximum 48000 on my 1 TB SSD boot drive. when I first set this up I was amazed with initialization speeds with all apps and access speed to my 5 other HDD on my system. No Lag it's just instant! Even web pages load faster. This system works for me.

[dreamdarkness]

For HDD, this is very useful as it helps to mitigate fragmentation.

Great video to the point clearing the air on this subject

Was wondering if you have a video or can do a video on Ms config using all cores and threads or let Windows manage them

[Overonator]

It would be nice someone to actually prove via benchmarks that manually setting page file makes any difference in performance.

[MuzdokOfficial]

Great video. Finaly someone adressed this topic.

Ive found matching the page file maximum with the installed ram does increase the efficiency. Bumping the initial size at 60% to create a target index. All together, Offloading hefty tasks in the background should help considerably. Bumping virtual ram is very much like adding racing fuel to a car that isnt made for racing-- its doAble but a stretch. Useful? Yes; To make ends meet with budget limitations. Example. 8gb installed ram: Match with approx 8000mb of vRam, with the initial size of 5200mb. For an exact calculation; in task manager look at Available Memory* this number shows up as less than installed ram as the cache bank and other system needs' take up space at boot. 8gb would be approx 7gb of usable memory. Goodluck

[ethimself]

I usually have it set to - Windows Management, although I sometimes set it to off as in zero. I always have more than enough RAM free. I find that there are no performance differences that I can perceive with any settings

[rogerbowen]

Thanks for confirming something I've always thought. You get so many 'experts' quoting these magic pill solutions, using weird formulas and buzzwords to make it sound like they know what they're on about, when clearly they don't. One thing I constantly hear people bang on about is 'memory leaks', are these real, or just another 'expert' buzzword!? Whenever a game causes an issue, out they come "There's a memory leak!". Can they prove it!? Well, they like to think they can!

[just-simplymarvelous]

It is people like younthat actually makes the world turn. !God bless you, Sir!🍎

[jonrend]

Classic man. I was bought up on VMS (Virtual Memory System - DEC) and Windows NT 3.5. Paging is part of the architecture of the OS, It's almost like trying to turn off the Kernel on Linux lol. Paging is meant to happen be it a hard fault or a soft fault. My advice has always been, if you concerned about paging affecting your performance then buy more memory you will still page but you can reduce your hard paging to disk although it will increase your soft paging to memory, which is fine.

[SoulPoetryandOtherWorks]

Back on Windows 95 and XP when using a slow mechanical hard disk with older processors. Setting the swap file to a fixed size of 1.5 times the installed memory did speed things up at the expense of permanently losing that disk space. It would also help prevent fragmentation of the file on the hard drive.

With SSDs and today's faster processors, playing with these settings is useless. Windows 10 and up also employs memory compression which makes storage of the swapped-out memory even more efficient.

So leaving it alone is my current advice to anyone. Today hardware can handle it.

This is much like the older advice of low-level formatting hard drives and adjusting their interleave settings became obsolete when faster more capable hardware became available.
