Pipe Dreams: Six P35-DDR3 Motherboards Compared

BIOS And Overclocking

Frequency and voltage adjustments are more than adequate, slightly exceeding expected P35 capabilities without instilling unrealistic goals in less experienced overclockers.

BIOS Frequency and Voltage settings (for overclocking)
FSB Frequency266 - 600 MHz (1 MHz)
Clock Multiplier AdjustmentYes
DRAM Frequency667/800/1066 MHz Data Rate
PCIe Clock100 - 131 MHz (1 MHz)
CPU Vcore0.85000 - 1.60000 Volts (0.00625 Volts)
CPU FSB Voltage1.25 - 1.55 Volts (0.10 Volts)
Northbridge (MCH)1.25 - 1.55 Volts (0.10 Volts)
Southbridge (ICH)Not Adjustable
DRAM Voltage1.50 - 2.20 Volts (0.10 Volts)
CAS Latency Range
tCAS: 5-8; tRCD: 5-10; tRP: 5-10; tRAS: 9-23

Unfortunately, the T-Series TP35D3-A7 Deluxe wasn't able to overclock whatsoever as received, likely due to its early-stage BIOS. An increase of even 1 MHz caused it to hang at boot and reset BIOS adjustments, and using Biostar's included overclocking utility for Windows caused an instantaneous system hang. We look forward to future BIOS developments for this board.

T-Series motherboard support kits are always designed to impress, with cables packed in a mesh bag alongside promotional items. This model's "freebie" is a pair of T-Series logo memory covers.

Biostar's four Serial ATA cables are only two less than the maximum number of internal drives supported, and these come with four separate four-pin to SATA power adapters. Biostar also adds an S/P-DIF digital optical plus digital coaxial audio breakout plate, but does not provide serial or parallel port breakout plates.

  • Dont get any biostar mobo, they all have capacitor problems in my experience.
  • Gigabyte GA-P35C-DS3R support up to 4GB DDR3 memory. However, could 8GBs 2x4GB DDR3 modules be used as long as it is within the top 1333 limit on the board?
