I have a ep45-ds3r mobo and I am using 2x2gb vitesta 800 ddr2 sticks 4-4-4-12-2t and I bought another 2x1 GB ram of same model and want to install them to run win7 64 better but it failed so I went to gygabite site to look up for updates and saw there are some bios updates (i have v 6) that can solve some memory issues. The big problem is The following: these bios updates are for 32 win version. So my question is: can I flash 32 bit bios driver from a usb in the starting screen so I can avoid The 64 bit error? If possible also help me out with some tips if u got time. Thanks in advance!
