For building my PCs I have various Gigabyte B450M S2H motherboards (that's an AM4 socket board) and I recently acquired 3 sets of 2x8GB G.Skill Ripjaws V DDR4 RAM (F4-3200C16D-GVR and F4-3000C15D-GVR) only to find out that the system becomes unstable with dual channel memory and activating the XMP profile.
System works fine at XMP with one stick and it works fine with two sticks at base speed 2133MHz
I searched my ass off on the internet and found a thread where some guys recommends to disable Gear Down Mode (which is a mode that suppoosedly makes RAM more stable
) . I didn't know what the **** Gear Down Mode was, but I did so in the BIOS and it appears to be stable now.
I don't want to sell a system and have a customer complaining in less than a week, so I want to throw a bunch of tests at the system to rest assured. Cinebench one minute, Furmark one minute, Windows built in memory test, a couple of minutes Prime 95. All fine.
What would you throw at it to be sure that the RAM is stable? 1h of Prime95? Memtest86? Any recommendations? I cannot seem to find a good mem test program that runs from Windows
