Memory for ASRock C2550D4I

[snakyjake]

Looking to purchase 4GB of memory for a home media/file server. The server will be performing file checksums (data integrity, data rot detection), software raid, file storage, media serving for the home.

I want data integrity, reliability, durability, and of course speed to reduce the time of data integrity checking.

I've narrowed it down to 4GB, dual channel, DDR3, 1600, 240 pin, ECC, 1.35v.

CAS: Looks like everything is 11.
Registered vs unbuffered: Registered seems to provide higher integrity for a file server.

Crucial offers the models:
CT4G3ERSLS4160B
CT4G3ERSLD8160B

Kingston offers models:
DDR3L ECC Reg SR x8 1.35V w/TS Elpida F
DDR3L ECC Reg SR x8 1.35V w/TS
DDR3L,SR x 4,w/TS,Intel

Do any of the choices make a difference?
Any reason to pick one over the other?

Thanks,
Jake

I don't think you can use Reg ECC DIMMs in the ASRock. So the two Kingston Reg ones I would rule out.

Confirmed. Don't get the Registered DIMMs. You need ECC UDIMMs
