Epox 8KRA2+ (KT600): KT600 Hits the Streets

FSB Overclocking Results

For FSB overclocking, the following setup was used on the Epox 8KRA2+:

Using the above overclocking setup we were able to reach a stable FSB overclock of 215MHz. Since the 8KRA2+ only supports a 1/6 PCI divider the AGP and PCI buses were running out of spec (66MHz/33MHz), which limited our potential FSB overclock. We wouldn’t be surprised if a 215MHz FSB overclock using a similar setup is about the best you’ll be able to get from motherboards based on the KT600 chipset, especially since Epox Socket A motherboards are usually at the very top of the FSB overclocking heap. As a reference, we’ve been able to easily reach over 220MHz FSB with several nForce2 Ultra 400 motherboards, due in part to the ability of these motherboards to lock the AGP and PCI buses. AGP/PCI bus locking is commonplace now and is what will continue to hold back VIA chipset-based motherboards from winning over overclocker’s hearts.
