Maxmem in Windows 7 / 8 / 10

[der8auer]

I recently had some trouble getting maxmem to work in my Windows 10. If I set maxmem in msconfig to e.g. 4000 it always resulted in 1.5 GB after reboot. I tried several things and in the end I found that this is working:

 

Run CMD as admin and use this command line:

 

bcdedit /set removememory 27000

 

27000 will remove 27000 MB of the available memory. Using 32 GB you will have ~5.5 GB with this maxmem setting.

 

Maybe you are all already aware of this but in case you had the same problem it might help you.

Thanks, have been thinking about how to solve it for benchmarks which require lots of memory for a time. But never really needed it. Now I won't have to research it!

der8auer posting hacks wTf?

thanks man!

Thanks, I was playing with truncatememory and guess what - it didn't work

[der8auer]

Yea I also tried truncatememory and it didn't work

It's because there's a memory hole in that location, I think most often from VGA memory being mapped there. Try something like 8GB and it should give you maxmem of maybe 5GB or similar depending on your system config.

I see B-die made people learn hacks too

Ya I was just noticing this also, what I have been doing is typing in 5400 and then rebooting and then typing 2050 and I get 2gb. Need to try it for 4gb

 

if I type in 2050 from the beginning it gives me 890mb

What benchmarks is this required for? I had thought it was only like 3d in w7 but apparently not.

[speed.fastest]

Geekbench 3 required it with some crazy b-die like mine LOL

Hi, just wanted to ask, how to "addmemory"  

Also is there some way, how to "recover" system, where i did remove 12gb and system stuck without loading ? (it was at 2,2 with or without maxmem) Or i have to made new copy. 

Thanks

do you mean you cant boot os? you can use the windows 7 usb recovery and fix mbr and bootrec in cmd 

[GtiJason]

I use

bcdedit /deletevalue removememory

This will undo bcdedit /set removememory entry and boot with all memory, aka 16gb bdie
