BIOS And Overclocking

Pipe Dreams: Six P35-DDR3 Motherboards Compared
By

The GA-P35C-DS3R supports the full range of processors from next-generation 45nm Core 2's all the way back to 130nm Pentium 4 Extremes, but overclocking the old processors to their limits might be problematic since the next step beyond 1.60V Core is 1.80V.

Getting back to modern processor overclocking, the FSB is adjustable to an unrealistically-high 700 MHz, but chipset and DRAM voltage options look perfectly reasonable.

BIOS Frequency and Voltage settings (for overclocking)
FSB Frequency 100 - 700 MHz (1 MHz)
Clock Multiplier Adjustment Yes
DRAM Frequency FSB clock x 1.2, 1.5, 1.6, 2.0
PCIe Clock 90-150 MHz (1 MHz)
CPU Vcore 0.5125 -1.60 - 2.00 Volts (0.00625/0.2000 Volts)
CPU FSB Voltage 1.20 - 1.50 Volts (0.10 Volts)
Northbridge (MCH) 1.20 - 1.50 Volts (0.10 Volts)
Southbridge (ICH) Not Available
DRAM Voltage 1.50 - 2.200 Volts (0.10 Volts)
CAS Latency Range
tCAS: 4-10; tRCD: 1-15; tRP: 1-15; tRAS: 1-31

The GA-P35C-DS3R accomplished only 3.42 GHz at 1.50V from an E6700 known to reach 3.46 GHz on top boards, but jumped to an impressive 456 MHz bus clock (FSB1824) when the CPU multiplier was dropped to 6x.

Accessories

Gigabyte did not have an accessory pack ready for its GA-P35C-DS3R in time for the review, but considering the eight internal SATA ports, an eSATA breakout plate might be worthy of the company's consideration.
