VGA card holding 3GB system memory - no option in bios to disable

I have googled this to no end, so now I post...

I have 6gb system memory. 3gb is available to windows.
My GTX750 is holding this extra memory- this was confirmed by checking graphics memory in DXDIAG - my card shows to have 4GB which accounts for the lost memory.

Google is full of a million hits of the same two fixes:

1- msconfig > boot > advanced > remove memory limit --- No memory limit has been set, this is fruitless.

2- Check bios and reassign the memory back to the system. --- Just spent half an hour going through my BIOS - there is absolutely no option, at all, anywhere to do this. I have used hundreds of different BIOS in my time - so this totally baffles me.

Anyone have experience with this board?

Test the RAMs one by one, check what they each report in resource monitor.

This isnt the problem dude. People who post "quick fixes" without even reading threads properly really irritate me.


Every stick of RAM works totally fine.


The problem is that 3gb of my system ram has been unnecessarily given to my video card.

If you read my post properly you would know that this is clearly not a case of bad ram. Bad ram would stop the PC booting or not show up at all.

This is a memory assignment issue.

When you open memory tab of Resource monitor, do they show as hardware reserved? Post a screenshot.

How is 6GB formed? 3x2GB - 4+2GB? Dual-channel enabled in BIOS ganged/unganged?

Just as examples
Hardware Reserved Ram 8GB! [Solved] - RAM - Memory - ram incompatibility
6GB of "Hardware Reserved" memory? [Solved] - Memory - Memory - 4+2 incompatibility
Hardware reserved ram [Solved] - Corsair - Memory driver issue
BIOS/Windows recognizes half memory [Solved] - Memory - Memory - check the last posts

Try uninstalling the GPU driver/may also be chipset
Try a clean restart (Troubleshoot Application Conflicts by Performing a Clean Startup)
Try in Safe Mode

Some people with dual boot say Win7 is reserved while 8 is ok, etc.

I won't say to run memtest now, but do start one when you go to sleep to eliminate the doubt, nothing more.

Layback Bear I have already stated that there is NO maximum limit set in msconfig. This is one of the results google pumps out a thousand times. I've seen this fix before, if it was the problem I wouldn't be posting here. No need for that screenshot as it wont tell you anything useful.
