ErrorCorrection	0x01 - Other 0x02 - Unknown 0x03 - None 0x04 - Parity 0x05 - Single-bit ECC 0x06 - Multi-bit ECC 0x07 - CRC	Specifies the primary hardware error correction or detection method supported by the memory. 0x01 - Other Sets hardware error correct to other. 0x02 - Unknown Sets hardware error correct to Unknown. 0x03 - None Sets hardware error correct to None. It's advised to set this option to "0x03 - None." Unless you're sure of your memory. 0x04 - Parity Sets hardware error correct to Parity. 0x05 - Single-bit ECC Sets hardware error correct to Single-bit ECC. 0x06 - Multi-bit ECC Sets hardware error correct to Multi-bit ECC. 0x07 - CRC Sets hardware error correct to CRC.
FormFactor	0x01 0x02 0x09 0x0D 0x0F	Specifies the form factor of the memory (RAM). On Macs this should usually be DIMM or SODIMM. 0x01 Sets Memory Form Factor as Other 0x02 Sets Memory Form Factor as Unknown 0x09 Sets Memory Form Factor as DIMM If you're using a PC, use this option. 0x0D Sets Memory Form Factor as SODIMM If you're using a Laptop, NUC, or All Ion One PC, use this option. 0x0F Sets Memory Form Factor as FB-DIMM
Type	0x01 - Other 0x02 - Unknown 0x0F - SDRAM 0x12 - DDR 0x13 - DDR2 0x14 - DDR2 FB-DIMM 0x18 - DDR3 0x1A - DDR4 0x1B - LPDDR 0x1C - LPDDR2 0x1D - LPDDR3 0x1E - LPDDR4	Defines the memory (RAM) type. 0x01 - Other Sets Memory Type as Other 0x02 - Unknown Sets Memory Type as Unknown 0x0F - SDRAM Sets Memory Type as SDRAM 0x12 - DDR Sets Memory Type as DDR 0x13 - DDR2 Sets Memory Type as DDR2 0x14 - DDR2 FB-DIMMM Sets Memory Type as DDR2 FB-DIMM 0x18 - DDR3 Sets Memory Type as DDR3 0x1A - DDR4 Sets Memory Type as DDR4 0x1B - LPDDR Sets Memory Type as LPDDR 0x1C - LPDDR2 Sets Memory Type as LPDDR2 0x1D - LPDDR3 Sets Memory Type as LPDDR3 0x1E - LPDDR4 Sets Memory Type as LPDDR4
TypeDetail	2 - Other 4 - Unknown 128 Synchronous 8192 - Registered (buffered) 16384 - Unbuffered (Unregistered)	Defines additional memory type information. It's advised to set the TypeDetail to 4 (0x04) - Unknown. Unless you're sure of your memory. 2 - Other Sets Memory Type as DDR4 4 - Unknown Sets Memory Type as LPDDR 128 - Synchronous Sets Memory Type as LPDDR2 8192 - Registered (buffered) Sets Memory Type as LPDDR3 16384 - Unbuffered (Unregistered) Sets Memory Type as LPDDR4
