FES7510
Fanless Embedded Controller comes with
Intel Celeron M ULV Processor
DRAM TIMEING SELECTABLE:
The value in this field depends on performance parameters of the installed memory chips (DRAM). Do not
change the value from the factory setting unless you install new memory that has a different performance
rating than the original DRAMs.
CAS LATENCY TIME:
When synchronous DRAM is installed, the number of clock cycles of CAS
latency depends on the DRAM timing.
DRAM RAS# TO CAS# DELAY:
This item let you insert a timing delay between the CAS and RAS strobe signals, used when DRAM is
written to, read from, or refreshed. Fast gives faster performance; and Slow gives more stable perfor-
mance. This field applies only when synchronous DRAM is installed in the system. The choices are 2 and
3.
DRAM RAS# PRECHARGE TIME:
If an insufficient number of cycles is allowed for the RAS to accumulate its charge before DRAM refresh,
the refresh may be incomplete and the DRAM may fail to retain data. Fast gives faster performance; and
Slow gives more stable performance. This field applies only when synchronous DRAM is installed in the
system. The choices are 2 & 3.
SYSTEM BIOS CACHEABLE:
Selecting Enabled allows caching of the system BIOS ROM at F0000h- FFFFFh, resulting in better system
performance. However, if any program writes to this memory area, a system error may result.
VIDEO BIOS CACHEABLE:
Select Enabled allows caching of the video BIOS, resulting in better system performance. However, if any
program writes to this memory area, a system error may result.
PEG/ ONCHIP VGA CONTROL:
PCI-Express Graphics / On-Chip VGA Select
ON-CHIP FRAME BUFFER SIZE:
On-Chip VGA Frame Buffer Memory Size Select
