PS5
MT61K512M32KPA-14C:C D9ZPL — PS5
MT61K512M32KPA-14C:B D9XKV — PS5

Micron GDDR5X
MT58K256M321JA-100ES:A (2500MHz) Z9TXT — Sample GTX 1080/Titan
MT58K256M321JA-100:A (2500MHz) D9TXS — GTX 1080
MT58K256M321JA-110:A (2750MHz) D9VRL — GTX 1080 Ti
MT58K256M321JA-120:A (3000MHz) D9VRN — GTX Titan XP

Special note about GDDR5X usage
D9VRK (MT58K256M321JA-120:A) is the fastest, so it can be used on all.
D9VRN (MT58K256M321JA-120:A)
D9VRL (MT58K256M321JA-110:A) it can be used on TXS but not on VRK.
D9TXS (MT58K256M321JA-100:A) can only be used on TXS.

Micron GDDR5
MT51J256M32HF-80:A (2000MHz) D9TCB — GTX 1070/1070 Ti
MT51J256M32HF-80:B (2000MHz) D9VVR — Radeon RX 580
MT51J256M32HF-70:? (1750MHz) D9SSX — Radeon RX 470
MT51J256M32HF-70:B (1750MHz) D9VVQ — Radeon RX 580
MT51J256M32HF-70:A (1750MHz) D9SXD, D9TRV — Radeon RX 460
MT51J256M32HF-60:A (1500MHz) D9SXC
MT51K128M32HF-60 N:B D9XDL — Radeon RX 570
MT51K256M32HF-60 N:B (1500MHz) D9VVW
MT51J256M32HF-60S:A (1500MHz) D9TRZ

Special note about GDDR5 usage
D9VVR (MT51J256M32HF-80:B) should work in place of D9TCB (MT51J256M32HF-80:A).

Same part number, but a later revision.
80 (8Gbits/s) is already the fastest for GDDR5, so you can’t use MT51J256M32HF-70 or MT51J256M32HF-60 in a card that calls for 80.
