Reported by Lennard Seah on Wednesday, October 12 2011 12:02 pm
It is often debated that using more expensive "enthusiast-grade" memory will help application and gaming performance. We use the latest AMD FX-8150 8-core processor and ASUS ROG Crosshair V Formula 990FX to find out if that holds true for the Bulldozers...
Test Setup
- CPU: AMD FX-8150 8-core/8 thread processor @ 4.7Ghz (all power saving options disabled)
- Motherboard: ASUS ROG Crosshair V Formula (BETA 9905 bios made by Shamino - with latest BD AGESA, unlocks higher memory multipliers up to 2400)
- Graphics: AMD Radeon 6990 (Crossfire) with Catalyst 11.10 Preview 2 (8.901.2.0)
- HSF: Thermalright Silver Arrow with 2 Fans
- SSD: Corsair X128 SSD
