ASrock K8NF4G-SATA2 (C51G) Intro 5/5
Bluetooth 19 Sep 2005

BIOS II

The CAS Latency, TRCD, TRP and TRAS should be quite familiar to regular readers of OCW. This controls the ram timings. For our RAM, it is defaulted to CAS 2, 5-2-2. For ram compatibility, you can turn flexibility ON but this will reduce the perfomrance. CPU-NB link speed can be set to 200 (1x), 400 (2x), 600 (3x) , 800(4x),1000(5x). This is one of the determinating factor if you want to o/c the CPUclk to ensure max HTT of 1GHz is not reached by supplying a lower CPU-NB e.g. 800 (4x)
 
DRAM Voltage is adjustable and we see that ASrock has put in more options. We have AUTO, Low, Normal, High and Ultra High.

Auto -> set to high (2.65V)
Ultra High -> 2.7V
High -> 2.65V
Normal -> 2.6V
Low ->2.5V
