TWIN2X2048-6400C4D and Asus P5B Deluxe Detailed SPD Settings?

[timbo3282]

I read the setting for my memory following the link is your signature, but it does not seem to apply directly to my memory/motherboard combination. I notice that these settings are not specifically for my motherboard. I have commented below where I have questions specifically.

 

Testing parameters for Twinx/XMS2-6400C4:

Twin2x2048-6400C4 Data Sheet

 

Motherboard make and model: Asus P5WD2 or M2N32-SLI 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 Don't I want this at 266?

DDR2 SDRAM Clock: Manually set to 800MHz I have this set at DDR2-800MHz

Here you go. You were correct :)

Sorry I must have hit enter and posted before I meant to. Here is what I was trying to post:

DRAM Timing Selectable: Manual

SDRAM CAS Latency: 4T I have this set at 4T

SDRAM RAS to CAS Delay (tRCD): 4T I have this set at 4T

SDRAM Row Precharge (tRP): 4T I have this set at 4T

SDRAM Active to Precharge Delay (tRAS): 12T I have this set at 12T

SDRAM Write Recovery Time: 5 I have this set at 5T

There is a setting DRAM TRFC default setting 42 is that correct?

There is a setting DRAM TRRD default setting is 10 is that correct?

There is a setting Rank Write to Read Delay default setting is 10 is that correct?

There is a setting Read to Precharge Delay default setting is 10 is that correct?

Write to Precharge Delay: 15 (If it's Listed) This is set to 10 by default should I change to 15?

Command Rate: 2T Does this setting apply to my motherboard and if so what is the correct setting and where is it found?

DDR2 SDRAM Voltage: 2.1 I have this set to 2.1V

CPU Core Voltage: Auto I have this set to Auto

FSB Termination V: 1.50 V 1.50V is not an option I have the option of Auto, 1.200V, 1.300V, 1.400V, 1.450V which is the correct setting?

I have a setting for NB VCore with the options of Auto, 1.25V, 1.45V, 1.55V, 1.65V with a default of Auto which is the correct setting?

I have a setting SB Vcore(SATA,PCIE) with the options Auto, 1.50V, 1.60V, 1.70V, 1.80V with a default of Auto which is the correct setting?

MCH Chipset V: 1.65V Is this one or both of the previous two settings?

ICH Chipset V: 1.20V I have the option of Auto, 1.057V or 1.215V with a default of Auto which is the correct setting?

Are there any other setting for my motherboard that I am missing?

All other settings are motherboard defaults.

Maximum DDR2 recommended VDIMM: 2.1 Volts

 

Thanks for any help/advice!

Note that I had removed what was unecessary such as Command Rate from your settings in my prior post.

This is all you need worry about. Leave all else on Auto or Default.

Thanks DerekT! :D:

The FSB Termination Voltage I have max of 1.450V is that what I want? The previous post says 1.500 but I can't set it there.

 

Also MCH Chipset is that NB VCore or SB Vcore or both on my mobo?

 

Thanks

[timbo3282]

Also I have to set ICH Chipset Voltage to 1.215V 1.200V is not an option. Is that correct?

[DerekT]

The FSB Termination Voltage I have max of 1.450V is that what I want?

 

Set to 1.450V

The MCH VCore is the NB VCore.

 

Also I have to set ICH Chipset Voltage to 1.215V 1.200V is not an option. Is that correct?

 

You can set this to "AUTO"

Thanks again DerekT, everything seems to be working OK.

You're very welcome.
