Probably ECC SDRAM. It doesn't work in boards that don't support ECC.
ECC SDRAM works fine in boards that don't support ECC, just like parity SIMMs work in non-parity boards, you just don't get the error detection/correction.
You're probably thinking of registered vs unbuffered. Registered DIMMs won't work on boards designed for unbuffered and vice versa. A lot of ECC DIMMs are also registered, and the vast majority of registered DIMMs also use ECC, but it's the registers, not the ECC, that breaks compatibility.
However as has already been pointed out, this is a custom unit from a RAID controller.

Looks like a 50pin SCSI drive controller. Also have a disc on chip that used to be a storage solution mostly on embedded systems.
Don't think it's SCSI, for starters it has "MATRIX CONTROL" next to it. Also there's nothing on that card that looks like a SCSI controller, and not enough discrete logic to do it with that.
The sticker on the DiskOnChip (which is on ISA bus so by default basically IDE) says "EDR-1600", which leads me to this:

Looks like a custom card from a security system. Those 50p connectors are for some custom I/O to control the 16 channel video matrix it can display.
Without the rest of the system, what you have there is a rather large ISA DiskOnChip interface, i.e. an SSD 😉

Thank you for the help
So basically useless stuff since I dont have a securitex surveillance system and a RAID controller loool 😀
