Please advise where my bottleneck is. Muchos Gracias Link to comment Share on other sites More sharing options...
DerekT Posted November 15, 2007 Share Posted November 15, 2007 Lets see how 3.0Ghz works. Download memtest from http://www.memtest.org and extract the ISO image. Burn the ISO image to an CD-ROM disk. Enter your BIOS. On the main BIOS screen press Ctrl + F1. You will see the screen flicker. Next select the MB Intelligent Tweaker option. On that screen you will see many additional settings that were not there before. MIB Intelligent Tweaker (M.I.T.) CPU Clock Ratio = 9 CPU Host Clock Control = Enabled CPU Host Frequency (Mhz) = 333Mhz PCI Express Frequency = 100Mhz C.I.A.2 = Disabled System Memory Multiplier = 2.4 (then Try 2.6) DRAM Timing Selectable = Manual CAS Latency Time = 4 DRAM RAS# to CAS# Delay = 4 RAS# Precharge = 4 Precharge Delay (tRAS) = 12 ACT to ACT delay = Auto Bank Write To READ Delay = Auto Refresh to ACT Delay = 0 Read to Precharge Delay = Auto Memory Performance Enhance = Normal Dimm OverVoltage Control = +.3V PCI-e OverVoltage Control = Normal (G)MCH OverVoltage Control = +.02 CPU Voltage Control = Auto Robust Graphics Booster = Auto System Memory Multiplier takes the FSB and multiplies it to get the DRAM bandwidth. FSB = 333 so 333 * 2.4 ~= 800Mhz with 4-4-4-12 @ 2.1v 333 * 2.6 ~= 865Mhz with 4-4-4-12 @ 2.1v Run memtest on each test. Boot to the optical drive with the memtest disk and allow for two full passes. This will give your quad core a 3.0Ghz and some decent ram throughput. Link to comment Share on other sites More sharing options...
