You should use an unbuffered DDR3 (DDR3L might fit too) without ECC. An ECC version could function but the ECC feature might be skipped or not used. Registered buffered memory won’t work.
Just to confirm: you're looking for information about RAM compatibility for a specific Dell OptiPlex 7010 model. You want to know which types of RAM it supports. From what I found online, there seem to be at least three variations—DT, SFF, and USSF. This could be important because it suggests the device likely doesn't support high-speed buffered memory, as it's meant for a budget workstation. However, this isn't certain. Dell’s official site isn’t very clear on this, and the part number for the SFF 7010 is DP/N: GXM1W with a board model LA0601. The SFF version has four RAM slots but doesn’t support ECC memory. It also indicates multiple motherboard models exist for different 7010 variants, so the details are still unclear. Update from a user who thinks this is more reliable.
I reviewed the processor options in the technical details and identified the socket type. Cannot use server memory with socket 1155; buffered/registered memory isn't supported by these chips... refer to the i5 3770 page: https://ark.intel.com/content/www/us/en/...0-ghz.html. Also mentions ECC: No. Intel doesn't turn it on for desktop CPUs, which pushes you toward workstation or server models if you need ECC support. It depends on the motherboard BIOS to let ECC DDR3 sticks function normally. Regarding DDR3L, it's not listed on the Intel site for these processors, but it's just standard DDR3 at a reduced voltage (1.35V vs 1.5V). Most DDR3L modules will work fine at 1.5V, though they may run slightly hotter—think of it as a minor overclock.
