Polowogs :
Just wondering if this motherboard supports DDR4 ram. Friend has some he doesn't need.
Hello Polowogs. As you can see in the official Asus website. the M5A78L-M/USB3 doesn't support DDR4 RAM:
https://www.asus.com/uk/Motherboards/M5A78LMUSB3/specifications/
If you don't want to open the link I'll leave here the specifications considering the RAM:
(...) 4 x DIMM, Max. 32GB, DDR3 2000(O.C.)/1866(O.C.)/1800(O.C.)/1600(O.C.)/1333/1066 MHz ECC, Non-ECC, Un-buffered Memory
Dual Channel Memory Architecture
* Refer to www.asus.com for the Memory QVL (Qualified Vendors Lists).
* Due to OS limitation, when installing total memory of 4GB capacity or more, Windows® 32-bit operation system may only recognize less than 3GB. Install a 64-bit Windows® OS when you want to install 4GB or more memory on the motherboard.
* AMD FX Series CPU on this motherboard supports up to DDR3 1866MHz as its standard memory frequency.
* AMD AM3 100 and 200 series CPU support up to DDR3 1066MHz. (...)
I hope this was helpful. Good luck!
