BIOS and Overclocking
FSB Frequency | Stock-600 MHz (1 MHz) |
Clock Multiplier Adjustment | No |
DRAM Frequency | All Intel Ratios (by boot strap) |
PCIe Clock | 100 - 150 MHz (1 MHz) |
CPU Vcore | 1.10 - 1.60Volts (0.05 Volts) |
CPU FSB Voltage | None |
Northbridge (MCH) | None |
Southbridge (ICH) | None |
DRAM Voltage | 1.5 - 2.1 Volts (0.1 Volts) |
CAS Latency Range | tCAS : 3-11 ; tRCD : 3-15 ; tRP : 3-15 ; tRAS : 9-30 |
The X48T-A by ECS offers an excellent range of FSB frequencies and adequate voltage adjustments for 65-nm and 45-nm cores, but no clock multiplier, FSB voltage or chipset voltage controls. Furthermore, its DRAM ratio adjustment appears to be broken on BIOS release 04/28/2008.
DRAM settings are available for all Intel ratios, but changing them doesn’t alter the actual value.
Without any FSB or Northbridge voltage control, we didn’t think we’d get very far in our overclock attempts. Later in this article our overclocking comparison will prove otherwise !
