P5W DH and TWIN2X2048-6400 Timings?


Recommended Posts

Hi all:


I need some help. I have a ASUS P5W DH motherboard wunning a Core2Duo (Conroe) x6800 2.93Ghz.


I have 4 GB ram, 4 sticks of 1 gig, (2 pairs of Corsair TWIN2X2048-6400 2GB Kit DDR2-800).


This set specs say that it is


"Tested at 5-5-5-12-T1 latency settings at 1.9V

SPD programmed at 5-5-5-12-T1 values"


Running this sets with the Jumperfree Settings on Auto, the motherboard on POST says it's PC-5300. On auto it treats this memory as DDR2-667


I change the Jumperfree Settings to Manual and set the frequency to DDR2-800. Now on POST it says PC6400. Now it's right, I got DDR2-800


Now the problem is that when I run CPU-Z it tells me that the memory is running at 400.7Mhz, which is fine.


But the timings is the big deal:


CPU-Z says:


Frequency: 400.7 Mhz


Cas#Latency 5.0 clocks

RAS# to CAS# Delay 5 clocks

RAS#Precharge 5 clocks

Cycle Time (Tras) 18 clocks

Bank Cycle Time (Trc) 21 clocks


Now that's weird it's set at DDR2800 and tells me 5, 5, 5, 18, 21


It's supposed to be 5, 5, 5, 12, T1


I don't know what T1 is. I tried raising the DRAM voltage to 1.9V. But when I load CPU-Z it stills show me the same numbers.


Why can't I get the timings that this memory is supposed to have?


What should I do? Am I doing something wrong.


I tried to set the timing manually on the BIOS setup, to 5, 5, 5, 12, and T1 (?) But oh, wait there is no T1 as an option, the choices are only numbers.


Excuse my ignorance but I'm actually lost. Can you help me please?


Thanks a lot in advance!

Unfortunately I don't have a helpful reply- just wanted to chime in to say that I have the same components and am in the same boat as you.


My CPUZ SPD also reads 400Mhz 5-5-5-18 (TRC 22). I manually set to 401Mhz 5-5-5-12 (Trc reads 21) but get some funny errors sometimes (cant use DVDRW - Start.exe application failed to launch 0xc0000006... everytime i put in a CD in -grrr).


Best of luck.
