Upgrade Intel Core i5 to DDR3 RAM and switch to DDR4 memory.
Upgrade Intel Core i5 to DDR3 RAM and switch to DDR4 memory.
A motherboard with DDR4 support and an LGA1150 socket is typically a mid-range to high-end platform like the ASUS ROG Strix Z590 or the MSI MEG 16, which accommodate both memory types and the necessary socket.
Also consider the motherboard problems linked to DDR3 and 4 slots having mismatched pin counts, plus the notch placement variations. Most recent CPUs and the i5-4670 follow a similar pattern, with the memory controller integrated into the CPU itself. It’s likely the memory controller needs to handle DDR4 as well. The earliest Intel chips that supported DDR4 were Haswell-E, probably intended for server use if I remember right.
It seems you're looking for ways to improve your system's performance by upgrading components. For an Intel i5 4670, ensure your motherboard supports DDR4 and consider a compatible upgrade plan. Dimms can help with power efficiency, and checking compatibility guides will be useful.
Currently you have all the necessary components. If your system is functioning properly, proceed with upgrading RAM, CPU, and motherboard simultaneously.
