Hi,
I have a Windows PC for over 3 years with 16 GB RAM. I upgraded my graphics card from a nVidia 460 GTX to a 760 GTX and now Windows System Control Panel reports “Installed memory: 16.0 GB (usable: 7.99 GB)”. Also, Task Manager reports Physical Memory 8183 MB.
Looking at Control Panel -> Video -> Screen Resolution -> Advanced Properties, I can see:
Total Available Graphics Memory: 4096 MB
Dedicated Video Memory: 2048 MB
System Video Memory: 0 MB
Shared System Memory: 2048 MB
Not sure if those things are related… Maybe the video card is trying to get some shared memory from the system and even though it gets only 2 GB, the usable memory drops to 8 GB. Doesn’t make much sense, does it?
I tried some things like running msconfig -> system startup -> advanced options -> checking Max Memory and setting 16384 and rebooting, then unchecking and rebooting. Also, tried to look at the motherboard BIOS for some memory setting but found nothing. I guess the memory chips themselves are fine or Windows would not report “Installed memory 16 GB”. CPU-Z diagnostic program also reports Memory Size as 16 GBytes.
Some details about my build:
Operating System: Windows 7 Home Premium Edition 64-bit SP1 (Build 7601)
CPU: Intel(R) Core(TM) i5 CPU 760 @ 2.80GHz
Memory: 4 x 4GB DDR3 Corsair PC3-10700H (667 MHz)
Video: EVGA NVIDIA GeForce GTX 760 2 GB
Motherboard: ASUS P7H55
I’m lost here. Do you have any ideas? If you need some extra info, please do ask!
Thanks
