New to Overclocking with homebuilt Computer

Recommended Posts

I have a question to ask. I've read many Forum comments and am quite confused. I built my system with an ASUS P5W DH Deluxe motherboard, Intel 6600 Core 2 Duo, 700 Watt Thermaltake power supply, 2 Gigs Corsaire PC2 6400 RAM, XFX 8800 GTX videocard. When I try overclocking my CPU, either through the BIOS or using ASUS AI Booster my memory frequency goes way down and latency goes way up. When I overclock my RAM my CPU speed goes way down so I just can't win. I'm trying to overclock my memory (or keep it at 800 MHz) while at the same time overclock my CPU. I've tried increasing the memory voltage but that didn't do it. I'd really appreciate anyone's help.... Thanks... Louis

Try these settings:


Configure System Frequency/Voltage

  • AI Overclocking = Manual

  • CPU Frequency = 325

  • DRAM Frequency = 667MHz

  • Performance Mode = Auto

  • PCI Express Frequency = 100

  • PCI Clock Synchronization Mode = 33.33


  • Memory Voltage = 2.1v

  • CPU Core Voltage = Auto

  • FSB Termination Voltage = Auto

  • MCH Chipset Voltage = Auto

  • ICH Chipset Voltage = Auto

Advanced Chipset Settings

  • Configure DRAM by SPD = Disabled

  • DRAM CAS# Latency = 5

  • DRAM RAS# Prechardge = 5

  • DRAM RAs# to CAS# Delay = 5

  • DRAM RAS# Activate to Precharge: 15

  • DRAM Write recovery Time = 4


Leave all else on AUTO settings. Download Memtest from http://www.memtest.org and write the image to a CD. Boot to the CD and allow a few passes. Please post screenshots of CPU-z's CPU, Memory and SPD tabs.
