P5E3 + TW3X4G1333C9DHX instability

[Syntic]

Hi,

 

I've been on and off this site for several months now trying to get my setup stable, but after attempting several configuration recommendations (mainly by RAM GUY), I'm still unable to get my system to run stable.

 

Initially when I put the RAM in, I ran the system defaults which set my RAM to run at 533Mhz w/ 7,7,7,20 timings. This seemed to be okay, but I would see the system become unresoponsive when attempting to do some CPU intensive tasks (by unresponsive I would get a frozen screen and USB devices would loose power)

 

After doing some reading I set my memory to run at recommended frequency and timings (which took me quite a while to get working at all!), but now I'm seeing BSOD occuring quite often.

I played with a few settings like NB voltage, RAM voltage, DRAM command rate, but I can't quite get the system completely stable.

 

I know there are a few threads on this type of issue already, but I would really appreciate it if someone could take a look at my settings and recommend any changes that may help?

 

Below is current BIOS config

FSB Freq - 333

DRAM Freq - DDR3-1333Mhz

DRAM Command Rate - 1N

DRAM Timing Control - Manual

CAS# Latency - 9 DRAM Clocks

RAS# to CAS# Delay - 9 DRAM Clocks

RAS# PRE Time - 9 DRAM Clocks

RAS# CAT Time - 24 DRAM Clocks

DRAM Static Read Control - Disabled

DRAM Dynamic Write Control - Disabled

Ai Clock Twister - Light

DRAM Voltage - 1.80

CPU Spread Spectrum - Disabled

PCIE Spread Spectrum - Disabled

*All other settings are left as default and I'm running the most recent version of BIOS.

 

Let me know if you need further details.

 

Thanks!

DRAM voltage should be 1.6 V or as listed on label on DIMM. 1.8 V is unusually high for DDR3 RAM. Set Command Rate to 2T. Intel supports up to 1333 MHz. RAM frequency on the Q9450 CPU.

 

You can individually test each DIMM with Memtest 86+. If good then you could have a CPU/mobo/PSU issue however if the system is unstable at OE default frequency?

I set the DRAM voltage to 1.6V and I couldn't even boot into windows. I would get the pulsating Windows 7 logo, but it would halt after 1-2 seconds.

Didn't have the option for 2T, but used 2N instead (not sure on the difference).

 

I haven't ran Memtest as of yet, but I suspect the memory will be fine (I'll test it anyways).

I'm pretty sure it's just because the P5E3 is a POS. I had serious issues with OCZ memory when I first bought the rig. Shortly after I got the Corsair, but have still had issues.

 

I'm open to any other recommendations/testing :)
