According to the
MSI B85-G43 Gaming manual it is only possible to enable a maximum of 256M integrated graphics share memory in the BIOS.
I haven't checked the other MSI B85 motherboards as I have no interestes in any of the B85 motherboard - this is only ment to serve as a warning to others.
Gigabyte Z97 and H97 motherboards all seems limited to 512Mb shared memory.
Asrock Z97 motherboards seems to allow the maximum 1.7Gb shared memory.
I'm having a hard time finding similar data on MSI Z97 and H97 motherboards.
The closest I've come so far is the following line of text found on the [url=ttp://
www.msi.com/support/mb/Z97-GAMING-7.html#down-bios]Z97 Gaming 7 BIOS update page[/url]:
- Removed 1024MB option in "Integrated Graphics Share Memory" of BIOS.
My guess is that this means that it will not be possible to select more than 512Mb shared memory as the 1Gb option has been removed.
THIS thread indicates the same.
Interestingly the user "RemusM" has a different view on shared memory:
That BIOS setting is not your video memory.
That's the amount of pre-allocated system memory for CPU-IGD in order to work properly.
256MB is more than enough.
For your CPU (Core i5 4590 / HD4600):

Graphics Video Max Memory : 1.7 GB
The amount of graphics memory in use is dynamically allocated depending on the running application(s).
And you have no control over that value.
