gmowad Posted October 16, 2007 Share Posted October 16, 2007 I just tweaked my bios settings and looking for confirmation that I got it right: cpu external freq: 200Mhz cpu frequency multiple setting: auto x cpu frequency multiple: 13.0x system performance: user defined cpu interface: aggressive memory frequency: 200% resulting frequency: 400Mhz memory timings: user defined sdram active precharge delay: 6 sdram ras to cas delay: 3 sdram ras precharge delay: 3 sdram cas latency: 2t ddr reference voltage: 2.7v Also, I am thinking about upgrading from 512Mb to 1Gb. The DDR dimm installed right now is a cmx512-3200c2 (purchased in 2002). Can I purchase another 512Mb dimm and run in dual channel mode? cpuz.txt attached. Thanks!

DerekT Posted October 16, 2007 Share Posted October 16, 2007 Your motherboard will accept Dual Channel Mode but this board is very picky about the DRAM SPD settings. Be careful to purchase the correctly identical model of DRAM or you might well find yourself with 1GB in single channel mode. In that system, the difference is quite minimal though so I would not really worry about being in single channel mode. ~5% differential in most applications and games.

Corsair Employees RAM GUY Posted October 16, 2007 Corsair Employees Share Posted October 16, 2007 Both of the module would need to be the exact same part number and revision and when you go to two module you would need to set the memory Frequency at 100% so its in sync with the CPU.

RAM GUY, Thank you for your response. However, would you please expand on the bios settings? The reason I ask is because cpu-z and post now reports an AMD XP1500+ cpu: Processor 1 (ID = 0) Number of cores 1 Number of threads 1 (max 1) Name AMD Athlon XP Codename Palomino Specification AMD Athlon XP 1500+ Package Socket A (462) CPUID 6.6.2 Extended CPUID 7.6 Core Stepping A5 Technology 0.18 um Core Speed 1303.1 MHz (13.0 x 100.2 MHz) Rated Bus speed 200.5 MHz Chipset -------------------------------------------------------------------------- Northbridge NVIDIA nForce2 SPP rev. A2 Southbridge NVIDIA nForce2 MCP-T rev. A3 Memory Type DDR Memory Size 512 MBytes Memory Frequency 200.5 MHz (2:4) CAS# 2.0 RAS# to CAS# 3 RAS# Precharge 3 Cycle Time (tRAS) 6 Here is cpu-z prior to tweaking: Processor 1 (ID = 0) Number of cores 1 Number of threads 1 (max 1) Name AMD Athlon XP Codename Palomino Specification AMD Athlon XP 2100+ Package Socket A (462) CPUID 6.6.2 Extended CPUID 7.6 Core Stepping A5 Technology 0.18 um Core Speed 1737.4 MHz (13.0 x 133.6 MHz) Rated Bus speed 267.3 MHz Chipset -------------------------------------------------------------------------- Northbridge NVIDIA nForce2 SPP rev.

A3 Memory Type DDR Memory Size 512 MBytes Memory Frequency 133.6 MHz (1:1) CAS# 2.0 RAS# to CAS# 3 RAS# Precharge 3 Cycle Time (tRAS) 6 This cpu is not unlocked. So now I'm confused a bit about what the optimal settings are for my situation. Thank you! Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted October 16, 2007 Corsair Employees Share Posted October 16, 2007 Load setup defaults with the modules in slots 2-3 and then set these settings: Advanced Chipset Features Settings: CPU External Frequency = 133 CPU Frequency Multiple = 13x Memory Frequency = 100% System Performance = Optimal CPU Vcore = Auto AGP Frequency can be given the following values: 66Mhz DDR Reference Voltage – 2.7V AGP VDDQ Voltage – 1.5V Memory: SDRAM CAS Latency = 2.5T SDRAM RAS Precharge Delay = 3 SDRAM RAS to CAS Delay = 3 SDRAM Active Precharge Delay = 6 Then test with http://www.memtest.org Link to comment Share on other sites More sharing options...

I followed your recommendations and then tweaked some. I think it's about the best I can get it. Here is how it's configured now: These are the actual BIOS fields in the setup screen: CPU External Freq (Mhz): 133MHz CPU Freq Multiple Setting: Menu CPU Freq Multiple: 13.0X System Performance: User Defined CPU Interface: Aggressive Memory Frequency: 150% (Ram Guy recommended 100%) Resulting Frequency: 200MHz (any benefit here?) Memory Timings: User Defined SDRAM Active Precharge Delay: 6 SDRAM RAS to CAS Delay: 3 SDRAM RAS to Precharge Delay: 3 SDRAM CAS Latency: 2T xFSB Spread Spectrum: Disabled xAGP Spread Spectrum: Disabled CPU VCore Setting: Auto xCPU VCore: 1.750V Graphics Aperture Size: 64MB AGP Frequency: Auto System Bios Cacheable: Disabled Video Ram Cacheable: Disabled DDR Reference Voltage: 2.7V AGP VDDQ Voltage: 1.5V AGP 8X Support: Enabled AGP Fast Write Capability: Enabled I downloaded memtest from http://www.memtest.org and ran error free for over ten hours. If you have any additional thoughts or tweaks, please let me know. Thanks! Attached is revised cpuz report....cpuz final.txt Link to comment Share on other sites More sharing options...

Corsair Employees RAM GUY Posted October 18, 2007 Corsair Employees Share Posted October 18, 2007 If the system is stable at those settings and you are happy then go for it. However, you will get better performance with the memory in sync with the CPU. Link to comment Share on other sites More sharing options...
