Windows 10 Pro OEM 32 bit original installation.

 

This is your problem, a 32-bit OS cannot utilise any more than 4GB of RAM, see attached tables for Windows 10;

So it appears that if I install Windows 10 Pro OEM 64 bit, I can access all 64 Gb of my RAM and even more on future computer builds up to 512 Gb - whenever the computer stores have those types of motherboards.  Good to know, so that I can change the programs that I'm using to 64 bit versions.  I'm assuming that that is all the solution that I will need to know.  If not, please advise.

Yes a 64bit Windows OS install will allow you to use all the RAM that the MB supports.   If the original OEM disc you used has both 32bit and 64bit on the disc, you must do a fresh clean install of the 64bit version, there is no way to just change an installed version from one to another.   If both versions are not on the disc you have, you will need to purchase a 64bit OS install disc.

 

Warning.   Before installing a new OS, make sure that all switches on the MB are in the Default positions, Power up and enter the UEFI (BIOS) > then go to the Exit Menu,> select the Default or Safe setting, > press Enter > then confirm, yes or OK.   Your computer will restart.

You can now do a fresh clean install of the 64bit OS. 

 

The amount of RAM you have is excessive and wasteful for a gaming build.   I don't think you will ever use even 16GB, and that is with running background applications and gaming.   Your second 32GB kit will just sit there dong nothing.  Install 2 x 16GB sticks in the correct 2 slots.   Try to use a pair from the same kit.   Return the other kit.

Thanks.  Although I built a gaming class computer, it is not for gaming.  I need to open multiple programs to do multiple analysis and research that I do from home.  My previous computers kept running out of memory, so I concluded that I need more memory.  BYW, I keep hearing about tweeking stuff on the computers and I was wondering if the 32bit OS can be tweeked to use all the memory, otherwise I'll have to buy Windows again.

 

After I reset the BIOS and install the 64bit OS; can I still use the over-clocking procedure in the video that I included is my original post?

No a 32 bit OS can't give a transparent access to all the memory you have for all the programs you need to install a 64 bits OS.

Changing from 32 bits to 64 bits doesn't require that you purchase a new Windows license because the key you have isn't specific for an architecture only for an Edition.

 

If your Windows disk is only 32 bits then download Windows 10 64 bits Pro from Microsoft https://www.microsof...nload/windows10

 

Make sure that you uncheck the option Use the recommended options for this PC on the Media Creation Tool so you can select 64-bit (x64) architecture.

Hi PC Genie.

Noted why you wanted 64GBs or RAM.

Yes.

Thanks for your advice.  Yes, I've successfully installed the new Windows 10 Pro 64 Bit OEM OS and my RAM is now 64 Gb.  Also I've tried to Double Your Computer RAM for Free as explained in the YouTube video, but it appears that the process will take several days, because the process didn't get past the 1st pass when I left my computer on overnight.  According to this procedure, I'm supposed to end up with 128 Gb of RAM when it's done.  Has anyone done this and can advise me on this?

Thanks for the update.   Good to see you have the issue solved.

 

The doubling your RAM is bunk.   There is no software/tweaking way you can physically increase RAM quantity, only by installing more.   You can increase it's performance by overclocking.

The mention of Simulated annealing >https://en.wikipedia...lated_annealing Might possible be used by Windows for testing/analyzing memory, but could not increase it's size.

Most of the comments are taking the Micky.

If you are having problems, please start your own new topic.   That way, all members will see your post as against adding to a solved topic, which will get you limited replies.

 

Thanks. .
