Midnight703 Posted July 4, 2020 Share Posted July 4, 2020 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! 1 Quote Link to comment Share on other sites More sharing options...
keeph8n Posted July 4, 2020 Share Posted July 4, 2020 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. 2 Quote Link to comment Share on other sites More sharing options...
Midnight703 Posted July 4, 2020 Author Share Posted July 4, 2020 Thanks for the information! sounds like its best to play with the number some and figure out what OCs best for the rig? Quote Link to comment Share on other sites More sharing options...

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 2 Quote Link to comment Share on other sites More sharing options...
Midnight703 Posted July 6, 2020 Author Share Posted July 6, 2020 Yeah I was asking about DDR4. I really appreciate the detailed I info man that's a huge help! Quote Link to comment Share on other sites More sharing options...

exaberries Posted August 4, 2021 Share Posted August 4, 2021 (wanted maxmem in GB + 0.8) * 1024 is what I put into msconfig for windows 7 usually as a quick and dirty way to get close. I'm sure someone can give a more accurate way to calculate what the exact value you should enter Quote Link to comment Share on other sites More sharing options...
I.nfraR.ed Posted August 4, 2021 Share Posted August 4, 2021 I'm not sure if it is still the case, but removememory command has another advantage over maxmem from msconfig. If you set a maxmem value and want to increase it, then you need to delete the old value first, then reboot, set the larger value and reboot again. However, if you have clocked your B-Die with high voltage it would BSOD after first reboot (full memory capacity) and you have to reduce the clock/voltage. With removememory you can simply set a new value and reboot. Quote Link to comment Share on other sites More sharing options...
exaberries Posted August 4, 2021 Share Posted August 4, 2021 I've never personally had problems just changing without resetting with msconfig on windows 7. I think its the removememory/truncate memory that you have to reset before use but i've only ever tried that once on windows 10. Quote Link to comment Share on other sites More sharing options...
Broken APEX49 Posted August 11, 2021 Share Posted August 11, 2021 (edited) I am using Windows 7. I would like to know the optimization at super pi runtime. Edited August 11, 2021 by GTI-R Quote Link to comment Share on other sites More sharing options...
