Overclocking

The following table summarizes BIOS settings with a
AMD Phenom II X3 710 and OCZ Platinum 2X 2048MB DDR2 PC2-8500.

CPU Frequency	min 200 - max 550
Processor voltage	min + 50mv - max + 100mv
DRAM Frequency	min 333 MHz - max 533 MHz
PCI Express Frequency	min 100 - max 150
Memory Voltage	[AUTO][Min 1.850000V][Max 2.24375V]
Chipset Voltage	min + 50mv - max + 150mv
Hyper Transport Speed	min 200MHz - max 1.0 GHz
GPU Frequency	min 500MHz - max 1000MHz

In the BIOS there is a possibility to set the CPU Overclocking to [Overclocking Profile]. In that case the Overclocking Options are [Auto][Overclock 3%][Overclock 5%][Overclock 7%].

We started overclocking by using the overclocking profile in the BIOS and set it to the maximum value being 7%. We ran it for about half an hour with no problems. All this was done with the AMD stock cooler.

Manual overclocking the X3 710 was a lot higher, we reached 3315MHz with a base clock of 255MHz, a gain of 27.5%. Raising the CPU voltage didn't help, we couldn't get any higher then a BCLK of 255MHz. We used a Cooler Master Hyper TX 3 heatsink and the hyper transport and memory values were lowered during overclocking. We ran the 7zip benchmark using 6 threads for more than an hour.
