Intel® Qm57 Express Chipset; Timer - Kontron CP3002 User Manual

CP3002
Note ...
When the CP3002 is populated with 4 GB or 8 GB physical memory and used
with a 32-bit operating system, the CP3002 provides even less memory to
applications than indicated in the table above. In this event, the total memory
available to the applications depends on the system configuration.
Note ...
Only qualified DDR3 ECC SODIMM modules from Kontron are authorized for
use with the CP3002. Replacement of the SODIMM modules by the customer
without authorization from Kontron will void the warranty.
Note ...
To achieve full memory performance, it is recommended to populate both mem-
ory channels.

Timer

The CP3002 is equipped with the following timers:
• Real-Time Clock
The Intel® QM57 chipset integrates an MC146818B-compatible real-time clock with 256
Byte CMOS RAM. All CMOS RAM data remain stored in an additional EEPROM device
to prevent data loss.
• Counter/Timer
Three 8254-style counter/timers are included on the CP3002 as defined for the PC/AT.
• The Intel® QM57 chipset integrates eight high-precision event timers.
