TW3X4G1333C9DHX + P5E3 - Memtest Errors


Recommended Posts

So I have the classic problem with the Asus P5E3 , Corsair TW3X4G1333C9DHX combination , which , no matter how many bios changes I do, I can't solve it.


Bios Vers. = 505


Bios reseted to defaults


Only changed:


AI Tweaker


DRAM Freq = DDR3-1333Mhz

DRAM Command Rate = 2N

CAS# = 9

RAS# to CAS# Delay = 9

RAS# Pre Time = 9

RAS# Act Time = 24


DRAM Voltage = 1.62 ( tried 1.70 to but from what I've read this MB overclocks a bit )

NB Voltage = 1.41

CPU Spread Spectrum = Disabled

PCIE Spread Spectrum = Disabled


Advanced-> CPU Configuration


C1E = Disabled

Intel ® SpeedStep Tech = Disabled



Of course I get the usual symptoms:


  • Vista freezes on random periods of time
  • Mouse led is off
  • No keyboard response
  • For DRAM Voltage >= 1.7 the screen is filled with random color lines and then freezes


So again I do the usual Memtest Diagnostic. And funny after 3 successful passes I get this :

I tested with one Memory Module and no freezes and no errors.

So what shall I do? It seems that what ever I do this 4 GB Corsairs are just too much for this MB! :confused:

Two very possible events. If you were having data corruption issues due to lower voltages, then the corruption is still in the system and I would advise a fresh system install. Also, if you think that the power supply may be at issue, then remove a single video card and see if the issues repeat. You very likely have data corruption issues though and I would follow RAM GUYS advice to raise the DRAM voltage to 1.7v.

Intersting discovery


I let Memtest run for a week (lol that sounds desperate) and got no errors with this:


Bios Version : 803


C1E = Disabled

DRAM Voltage = 1.62 ( ram documentation says 1.70V , but this motherboard overclocks a bit)

NB Voltage = 1.41


CPU Spread Spectrum = Disabled

PCIE Spread Spectrum = Disabled


Rest on Auto.


But, while in Vista /Windows 7, with the same configuration the system freezes . So it must be an OS problem, probably a bad driver.

FYI, all tests were done on clean installations.


I installed 2 things.


1)Intel® Chipset Software Installation Utility which according to the documentation handles this:

- Core PCI and ISAPNP Services

- PCIe Support

- IDE/ATA33/ATA66/ATA100 Storage Support

- SATA Storage Support

- USB Support

- Identification of Intel® Chipset Components in

the Device Manager

2)The JMicron SATA driver


And until the moment of writing no problems occurred.



If you don't know what driver version to install , this app will do all the work for you
