The MSI RTX 2080Ti GAMING X TRIO also comes with Micron memory. I have an Asus ROG STRIX 2080Ti OC and a TITAN RTX and those come with Samsung memory modules (so says GPU-Z). I have the MSI 2080Ti Gaming X Trio (Micron memory), Asus Strix 2080Ti OC (Samsung memory), the Titan RTX (Samsung memory), and I just got in the EVGA 2080Ti FTW3 (have not opened the card or installed/tested yet so I don't know what memory it uses). All I can say is that all three cards I've tested work perfectly fine and the MSI and Asus both overclock pretty nicely (but I don't normally OC my GPU's unless I just wanna see how high they can go). Normally I leave them at how they came out of the box. I'm also going to try to test the Zotac AMP! Extreme but I plan on staying away from Gigabyte.
