Gigabyte 7VAXP-A Ultra: The KT400A in Retail Action

Performance Test Configuration

The AnandTech Motherboard Testbed was Sponsored by Newegg. You can buy the components we used to test at www.newegg.com.

Performance Test Details

All performance tests run on ASUS A7N8X Deluxe utilized two 256MB Corsair TwinX PC3200 modules set to CAS2/2T/4T/2T timings and running at 333MHz in single and dual channel mode. These settings yielded the highest performance we could possibly get from the ASUS A7N8X Deluxe (nForce2 SPP). For example, dual channel DDR400 mode was slower than dual channel DDR333 mode on the 333MHz DDR FSB we used, which is why nForce2 performance tests were run at a memory speed of 333MHz in dual/single channel mode.

All performance tests run on the Gigabyte 7VAXP Ultra (VIA KT400) and Gigabyte 7VAXP-A Ultra (VIA KT400A) utilized one 512MB Corsair XMS PC3200 module set to CAS2/2T/6T/2T timings and running at 400MHz. Any other performance-enhancing timings (like Command Rate, Bank Interleave or Top Performance) were enabled in KT400/400A motherboards that contained such timings. These settings yielded the highest performance we could possibly get from the KT400 and KT400A motherboards. For example, DDR333 mode was slower than DDR400 mode on the 333MHz DDR FSB we used, which is why KT400/KT400A performance tests were run at a memory speed of 400MHz.

FSB Frequencies

1. ASUS A7N8X Deluxe: defaults to 167.03MHz FSB.
