Request for RAM+CPU Configuration/Optimal Settings for new System

Recommended Posts

I got the new MOBO from Newegg.com this morning and this one isn't defective :) So now I need to know if there are certain settings I should change in my bios to make my Corsair Memory work better.

 

Running Windows XP Pro 32bit version OP system

 

AMD Athlon 64 x2 4200 Processor

 

Corsair TWIN2x2048-6400C4 Matched Memory Pair

 

x4 Western Digital 250 GB SATA II - Running Raid 5

 

Asus M2N-SLI Deluxe MOBO

 

Samsung DVD+- RW

 

Thanks for your time!

My board has way more and different options in it's BIOS so I am a bit lost as to how to get the settings changed to what I need by trying to follow this:

 

Testing parameters for Twinx/XMS2-6400:

Twin2x1024A-6400 Data Sheet

Twin2x2048-6400 Data Sheet

 

Motherboard make and model: Asus P5WD2 Premium/Deluxe

Each pair is tested and packaged together using the following settings:

AI Over Clock Tuner: Manual

CPU External Frequency: Manually set to 200MHz

DDR2 SDRAM Clock: Manually set to 800MHz

PCI Express Freq: Auto

PCI Freq: 33.33

Performance Mode: Standard

DRAM Timing Selectable: Manual

SDRAM CAS Latency: 5T

SDRAM RAS to CAS Delay (tRCD): 5T

SDRAM Row Precharge (tRP): 5T

SDRAM Active to Precharge Delay (tRAS): 12T

SDRAM Write Recovery Time: 5

DDR2 SDRAM Voltage: 1.9

Chipset Core Voltage: Auto

All other settings are motherboard defaults.

Maximum DDR2 recommended VDIMM: 2.1 Volts

 

If what it takes is listing every option in my bios then I will do it, I just figured you guys would have tested with the Asus M2N-SLI Deluxe Socket AM2 MOBO because it is such a popular in demand MOBO.

 

Please let me know ASAP what info you guys need from me to help me change my bios settings to optimal for what system specs I have.

 

Thanks much!

The settings in my BIOS for my MB are MUCH different then what is listed and I cannot get my BIOS to let my ram be set at the timings that I want. Have you guys tested with M2N-SLI deluxe or do I need to list out all the BIOS options in detail?

 

Please let me know ASAP, eager to get these timings and optimal configuration correct.

 

Also, this is what Newegg.com puts on this rams spec sheet:

 

# CORSAIR XMS2 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Unbuffered Dual Channel Kit System Memory Model TWIN2X2048-6400C4 - Retail

 

Cas Latency: 4

Features: EPP (Enhanced Performance Profiles) and also SLI certified

Heat Spreader: Yes

Manufacturer Warranty: Lifetime

Timing: 4-4-4-12

# Model #: TWIN2X2048-6400C4

# Item #: N82E16820145034

 

If this ram is Cas Latency: 4, why do you guys suggest using it with 5-5-5-12 timing settings?

I dont understand your question, the tested settings are Cas 4-4-4-12 the SPD is set to JEDEC values of Cas 5-5-5-15. The tested setting need to be manually set or with the MB you have just enable SLI ready memory is all u need to do!

I looked for enable SLI memory in my BIOS and there is no such option or I can't find it.

 

The BIOS is saying the current memory settings/timings are:

 

800MHZ-5-5-5-18-2T

 

These settings are DEFAULT settings nothing has been changed.

 

Again, if you need me to type out all the options in my BIOS I will do that if that is what is necessary to get help here.

 

Please let me know.

Corsair doesn't suggest 5-5-5-12, you were looking at a different part # on the spec FAQ. 5-5-5-12 is for the 6400s, you have 6400C4s. They're not up on the FAQ yet (dunno why).

Change your timings like so:

 

SDRAM CAS Latency: 4

SDRAM RAS to CAS Delay (tRCD): 4

SDRAM Row Precharge (tRP): 4

SDRAM Active to Precharge Delay (tRAS): 12
