B760M & B660M
DDR4 Boards

DDR5 kits are still $80–120 for 16GB. DDR4 is $40 used. For a sub-$550 build that delta matters. Every board here pairs with cheap used RAM and a 12th/13th gen i5. Used B660M from $70. New B760M from $114. Both chipsets. One honest guide.

The case for DDR4

Why Not DDR5

DDR5 kits still cost $80–120 for 16GB. Used DDR4 is $40 for the same capacity — two matched 8GB sticks from a reputable seller, dual channel, done. That $40–80 delta is a better GPU, more storage, or money back in your pocket. Both B660M and B760M support DDR4. Pick DDR4. Spend the savings elsewhere.

Note on DDR5 boards This guide covers DDR4 boards only. B760M DDR5 boards dominate eBay listings — most of what you see searching "B760M LGA1700" is DDR5. Filter explicitly for DDR4 or you'll end up with the wrong board for a DDR4 RAM build.

Buying Guide

B660 vs B760 — What Actually Matters

B660 is older, DDR4-native, and cheap used. B760 has better VRM, more PCIe lanes, and supports up to 14th gen Intel. At current pricing the MSI PRO B760M-P DDR4 at $114 new makes B760 the easy choice unless you're hunting sub-$90.

B760M DDR4 used supply on eBay is thin — most listings are DDR5. New B760M DDR4 on Amazon at $114 beats most used eBay prices. For B660M, used eBay is the right market. New stock has dried up and used boards are plentiful.

CN-shipped listings A significant portion of B760M and B660M listings on eBay ship from China. Delivery windows of 2–6 weeks, difficult returns, no US warranty support. Check itemLocation before buying. If it says CN — skip it.
