Windows 10: Can Windows 10 x64 use all 32GB of RAM the PC can has space for?

Hi,

Can Windows 10 x64 use all 32GB of RAM the PC can has space for? I would like to upgrade from 16GB if the OS can effectively use the additional memory. I have seen comments on the web but none from a credible source, thank you for your time. Jeff

Windows 10 Pro x64 32gb ram installed but only 16gb usable

I just upgraded to a 500GB SSD. Installed Windows 10 Pro x64. I have 32gb of ram. But windows 10 x64 is saying 16gb is usable. The UEFI motherboard bios sees the 32gb of ram. I did all the trouble shooting the motherboard manufacturer said to do, but
still didn't fix my problem. Anyone else having this problem? If so can you please inform me on how to fix this problem?

W7 x64 Pro and 32GB RAM

Okay I've built a system here with a Gigabyte Z68A-D3H-B3 rev 1.3 with the latest BIOS, Core i7 2700K, Sapphire Radeon HD 7950 3GB GDDR5, 128GB Crucial M4 SSD and 32GB of G.Skill DDR3 1600MHz RAM.

Windows 7 x64 Professional is loaded on the SSD. Windows 7 boots up lightning fast with 16GB installed but when I load in all 32GB it takes literally 5 minutes to load into Windows 7. This is at the loading screen where the 4 colors come together to form the Windows logo.

So it's a RAM issues right? Well here's the kicker.

It doesn't always take 5 minutes. Apx 1 out of every 3 or 4 bootups it will load in apx a minute or less. It's about 5 seconds longer than with 16GB but still acceptable and from what I can see Windows is pre-loading more into RAM on startup (2GB with 32GB, 1.25GB with 16GB) so the 5 seconds seems acceptable. But most of the time it takes 5 minutes and that is not!

I ran Memtest86+ overnight with not a single error. This is at the profiled 1,600MHz, 10.10.10 timings and 1.5v as stated on the sticks. I've also tried manually setting the speeds, timings and voltages. I've tried 1,333 (the mobo also defaults to 1,333 if XMP profile is disabled) and I tried upping the voltage. But like I said it passed memtest86+ running all night so I don't think it's a memory issue as much as a Windows issue.

Also when it does take 5 minutes to load up I should mention it's perfectly fast and stable once it does load in. It just seems to hang up on something while loading up Windows.

Like I said the board has the latest BIOS and I can't really try different RAM since I don't have 4x 8GB sticks lying around *Wink

Any tips would be great. I did search the issue and everyone else suggested it is a memory issue and suggested manually setting the clock speed, timings and voltage and like I said I did try that and it passed memtest86+ overnight on XMP profile so I don't believe it is a memory issue. Are there any other known software issues with Windows or Drivers and 32GB RAM?

PS it's not my PC it's a customer build. a customer who will never use or need 32GB of RAM but insisted on having it.... yeah. If it was mine I would just stick with 16GB as that would still be more than enough for me and it wouldn't be giving me any issues hahaha.

Thanks in advance guys

 

RAM Upgrade to 32GB, windows 10 won't start

1. Double check with your MB manual if the RAM is on the compatibily list
2. Make sure all the RAM sticks are firmly seated
3. Go into BIOS, under System Status and check for Total Physical RAM. Should be 32GB
4. Most of the time, The RAM voltage is set to Auto, manually set the voltage according to the RAM Spec.
5. If all fails, relax the RAM timing a little bit.
