Can IBM specific ram, such as
41Y2770 with ECC Chipkill, be used in non-IBM servers?
I know that the opposite is usually true, as I installed HP ram in a DELL just the other day (It was just normal ECC though, not ChipKill/ChipSpare).
However, because that RAM has chipkill, it will only work in motherboards that support ChipKill (the same as regular ECC DIMMs can only work in motherboards that support ECC). I know that there are some Tyan motherboards out there that support Chipkill, not sure about other brands.
When Chipkill was first created by IBM it was an ASIC on the SIMM/DIMM. These days Chipkill is standard as part of the memory controller and no special memory is required..
