i have a laptop with an eGPU build, and i think disabling sharded ram between eGPU and System will reduce the pci bandwidth between the card and EC. how would i go about disabling shared ram to the GPU? are there any programs that support this? there is NO option in my bios.
Do you mean Memory Mapped I/O, whereby in Resource Monitor you see a portion of your address space assigned to hardware?
Here's some more information - operating system - Memory mapped IO - how is it done? - Stack Overflow
I've just checked your System Specifications, and here's what I found:
The 512MB Graphics Memory will need to be mapped into the System RAM, as result of Memory Mapped I/O, read the above link and this link for a better explanation:Code:Radeon 540v 512MB Internal
There is no reason to change it, you want your video card to use as much memory as possible. I`m curious, could you post a few pics of the external gpu you have hooked up ?
I`m assuming you have it hooked to an external monitor, I mean how else could you use it.

I agree Quad10, the more RAM the GPU shares, the better the eGPU will perform. w7 is very good at allocating and using RAM.
yesbut with the eGPU having 1gb, i see no reason it would have to share system ram with it.

Maybe this will do it.
In the StartSearch type msconfig to open the System Configuration window, if UAC asks, allow it to run. Select the Boot tab and click the Advanced button. The BOOT Advanced Options window will open.
Uncheck the box for Maximum Memory if it is checked. Click OK, Apply and reboot for the change to take affect.
already unchecked lol let me try checking itMaybe this will do it.
