Can anyone help me!(Asus P5B-E+CM2X512-5400C4)

[masaemon]

First, sorry for my English.

I'm from Shanghai China,this is first time coming here, i searched a lot of topic but because i can't understand English very well....so, i created a new thread.

My story:

i bought CM2X512-5400C4 (x 2) at Shanghai this month, and installed it to my MB:Asus P5B-E, so my question is:

1)It is writed that the timing of CM2X512-5400C4 is 4-4-4-12@333MHz in its lable, but diffrent data is showed by CPU-z & Everest. that's 5-5-5-15@333MHz.Pls refer to attached pics. Can anyone tell me why?

 

2)i try to modify timing data in BIOS manually, but i don't know how to fill those too many items... Pls help.

 

Thank you all & Best Regards.

That is normal you would just need to set the tested setting manually which you can get from the link in my signature!

Hello, Thank you for your reply. i just read below contents, is it you want to let me read?

esting parameters for Twinx/XMS2-5400C4:

CM2X256-5400C4 Data Sheet

CM2X512-5400C4 Data Sheet

TWIN2X1024-5400C4 Data Sheet

Motherboard make and model: ABIT AA8 Durramax and/or Asus P5AD2 Premium

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

CPU External Frequency: Manually set to 250MHz

DDR2 SDRAM Clock: Manually set to 533MHz

DRAM Timing Selectable: Auto Yields the following timings

SDRAM CAS Latency: 4T

SDRAM RAS to CAS Delay (tRCD): 4T

SDRAM Row Precharge (tRP): 4T

SDRAM Active to Precharge Delay (tRAS): 12T

DDR2 SDRAM Voltage: 1.9

NB Voltage 1.9 Volts (On Abit AA8 Only)

All other settings are motherboard defaults.

Maximum DDR2 recommended VDIMM: 2.1 Volts

---------------------------------------------------------------------

 

i found this:

"DDR2 SDRAM Clock: Manually set to 533MHz ".

My question:

1)Would you kindly let me know which setting is correct from A & B below about my XMS2-5400C4?(i don't want to overclock,i just want to let it works with spec parameter)

A: 4-4-4-12 @ 667MHz

or

B: 4-4-4-12 @ 533MHz

 

:confused: :confused: :confused:

 

 

2)If A is the correct setting, pls see my BIOS setting screen:

DRAM CAS# Latency [4]

DRAM RAS# to CAS# Delay [4]

DRAM RAS# Precharge [4]

DRAM RAS# Activate to Precha [12]

DRAM Write Recovery Time Time [?] what should i set this value?there is no default to select.

DRAM TRFC [?] what should i set this value?there is no default to select.

DRAM TRRD [?] what should i set this value?there is no default to select.

RANK Write to Read Delay [?] what should i set this value?there is no default to select.

Read to Precharge Delay [?] what should i set this value?there is no default to select.

Any setting not listed should be left at Bios default or Auto!

Disable your "Static Read Control"

 

Repost your CPU-z, CPU, Memory tabs after this please.

OK, pls refer to attachment, it looks no any change...

Just load setup defaults and then exit saving changes and let the system try to Boot to a floppy and then restart and go back to bis setup and make the needed changes and leave all other setting set to whats listed.
