Hey everyone!

 

Pretty new here and am looking to take my memory OC up a notch! I know maxmem limits the memory used by windows so you can push high voltage an tight timings, but is there a guide or additional information I should know? Any info is appreciated!

Super high mems for geek and r15 like 2048 or so. 
 

3D depends on what you are running. 5gb or so usually works for newer. 3Gb or less for legacy.

Are you talking about DDR4 platforms ? Anyways maxmem is broken in some versions of windows, usually Windows 10 so you will want to use this method
Run CMD as Admin and type:

bcdedit /set removememory 11264

This will leave you with  5120mb or 5gb (using 16gb kit), and as Keep said good setting for 3dMark Firestrike and newer 3d
3dM01 - 06, 11, Vantage, Heaven, AM3 etc can use less like 3gb
To restore memory back to full 16gb just run CMD as admin again and type

bcdedit /deletevalue removememory

Other maxmem settings, Super Pi or Max mem freq on XP32 = 600 - 640mb
Geekbench 3, CBR 11.5/15, GPU Pi for CPU, wPrime/PiFast here or above setting: 1.9 - 2.2gb
HWBot X265: either no maxmem or around 7-8GB if having hard time getting good OC at around 1.6v ish
Point is you can get away running 600mb, 3gb, 5gb, 8gb and no maxmem set for most benchmarks
