A.
ECC RAM type
B.
Non-ECC RAM type
C.
ECC RAM type mixed with non-ECC RAM types
D.
All of the above
Explanation:
The ECC RAM type is usually used in server systems because of its capabilities of detecting and correcting parity errors. ECC RAM provides features such as data integrity, and stability. The ECC memory type found in most server systems is registered ECC CAS2.
Incorrect Answers:
B, D: While the non-ECC memory modules have higher performance levels than ECC memory modules, the stability provided by the ECC RAM type is far more important than the performance advantage provided by the non-ECC RAM types.
C: You should not use ECC and non-ECC memory modules interchangeably.
