Hello,
i have same problem face.secondary slot of ram is sometime working or sometime not.i clean the ram port but the problem being continued.....
how to fixed this issue?
have you ever update the gtm 740 p25 motherboard bios??
BIOS updates will not make your computer faster, they generally won't add new features you need, and they may even cause additional problems. You should only update your BIOS if the new version contains an improvement you need.
