I’m not sure where else to go with this, sorry if this isn’t the right place.

I’m currently designing a NAS build around an old CMB-A9SC2 motherboard that is self-described as an ‘entry level server board’.

So far i’ve managed to source all the other necessary parts, but i’m having a hell of a time finding the specified RAM that it takes:

  • 204-pin DDR3 UDIMM ECC

As far as I can tell, that type of ram just doesn’t exist… I can find it in SODIMM formats or I can find it in 240-pin formats, but for the life of me I cannot find all of those specifications in a single card.

I’m about ready to just throw the whole board away, but everything else about the board is perfect…

Has anyone else dealt with this kind of memory before? Is there like a special online store where they sell weird RAM components meant for server builds?

    I think it’s pretty safe to say that’s a typo on their part. Those slots are clearly the full length DDR3 modules so just look for any DDR3 unbuffered ECC DIMM and it should work.

    Also FYI non ECC ram should work if you don’t care about ECC. The memory controller is on the CPU side so as long as the mobo hasn’t fucked up/purposfully locked it out ECC/non ECC is only down to the CPU.

      That would make a lot of sense, since I’m finding builds with this board that have 240 pin ram listed.

      That is a frustrating typo though, makes me loose confidence in the product a bit

        I mean it’s an over 10 year old board. Unless you really want some of the server specific stuff you’re much better off getting something from the DDR4 era so you can snag much higher capacity ram for cheap. If it’s just a NAS then you really don’t need a “server” board, a regular consumer grade motherboard will do just fine as long as it has the I/O you need.
