Hi all! I’m based in the UK, and am planning to build a X570/B550-based system soon and am looking at my options for ECC memory. I’ll be starting with 32GB, but may go up to 64GB in time, so I’m looking at 16GB sticks. These generally seem to be Dual Rank, with Single Rank being rare in this capacity.
There are a few options out there, but official 3200Mhz options seem to be just about non-existent - Samsung’s M391A2K43DB1-CWE is still in Sample phase, while Micron’s MTA18ADF2G72AZ-3G2 doesn’t actually seem to be for sale anywhere I can reasonably buy from. The same goes for Kingston’s KSM32ED8/16ME, which uses Micron’s E-die chips. There is Micron MTA9ASF2G72AZ-3G2B1 (Single rank) order-on-request for £98 from a business supplier, but I’m not sure if they’re actually able to get it or how long it might take.
That leaves 2666Mhz options, which a number of people have reported overclocking with varying levels of success.
I can get:
- Samsung M391A2K43BB1-CTD (B-die) for £99
- Crucial CT16G4WFD8266-2G6D1 (Haven’t been able to find out what Micron calls this) for £89
- Kingston KSM26ED8/16ME (Micron E-die, maybe even chips binned for 3200Mhz) for £89
There are one or two Micron Very Low Profile options, but they seem to be 20% more expensive than non-VLP.
Are there any options I’ve missed? How should I go about choosing? Thanks!
