I recently did a new install of Windows 7 64 bit. I noticed windows showed 4Gb of ram (2.75Gb usable). I read tons of articles after googling this and tried several options to free up some more ram.
I have 2 options in bios to change memory remapping over 4GB. S/W and H/W.
When I enable S/W remapping, windows boots everything seems fine but I get a crackling sound from speakers. Bios shows 4Gb (3Gb usable). Windows shows 4Gb ram (3.0 available).
When I enable H/W remapping, windows BSOD during boot, but bios shows 4Gb ram and all 4 Gb available.
So, does anyone have any suggestions as to how to eliminate the BSOD after enabling H/W memory remapping? Try installing Windows 7 again? I read some people saying bump up the voltage on ram perhaps? I've never done any overclocking, but would try if someone thinks it may help.
I've tried several different setting. Any help would be greatly appreciated.
