Q. Can buffered memory be used with my AMD Athlon processor?
A. No. Use unbuffered memory only.
Q. I already have EDO memory or 66-MHz DIMM memory. Do I have to use PC-100-
MHz DIMM memory to run my AMD Athlon processor?
A. YES. The AMD Athlon processor does not run on EDO memory or 66-MHz DIMM
memory. The AMD Athlon processor requires, at a minimum, PC-100-MHz memory.
Table 2 outlines the PC-100 memory requirements.
Table 2. AMD Athlon™ Processor PC-100 Memory Requirements (PC-100 Rev 1.0 minimum)
Unbuffered
Speed of PC-100 memory chip
CAS/Latency of either 2 or 3
Error Correction Controlled (ECC)
6 ply (thickness)
Lifetime warranty
All of the above confirmed (written) on
the invoice
Q. Can I mix different brands of memory in my computer?
A. It is not advisable because some brands of memory are incompatible with other
brands regardless of whether the speed is the same or not. We recommend that you
use only one brand of memory in your computer system.
Q. Can I mix different nanosecond speeds of my memory modules?
A. Yes, but it is not advisable because the system will only use the memory speed of
the slowest memory chip. In other words, if you had two 32-Mbyte 7 ns memory
chips and one 32-Mbyte 8 ns chip, the system memory will operate at 8 ns. We
recommend you acquire memory modules of the same speed for consistent
performance.
