Model ThinkCentre A61 Series (Tower 9120, 9129, 9134, 9136, 9141, 9143, 9156, 9158, 9171, 9191-xxx) AMD Athlon 64 X2 Dual-Core / AMD Athlon 64 / AMD Sempron 1.66GHz - 2.70GHz
System Type Desktop
Standard Memory 512 (512MB x1 Removable)
Maximum Memory N/A (Please select your specific submodel above)
Sockets 4
Slots/Banks 4
Installation Notes System supports either 533MHz (STM3211/xxx) or 667MHz (STM4983/xxx) or 800MHz (STM2975/xxx) Unbuffered Non-ECC DDR2 SDRAM 240-Pin memory. Memory must be purchased and installed in matched pairs for Dual Channel Mode. NOTE: * If 4GB is installed, the recognized memory may be reduced to 3.5GB or less depending on system configuration (operating system) and memory allocation. To utilize the maximum configurations, this system will need a 64-bit operating system. When mixing the memory speed, the installed memory will run at the slowest memory speed. AMD Sempron processors support DDR2 533MHz and 667MHz memory only. DDR2 800MHz modules are not supported with this processor.
