Bad CMX512-3200 Module

Ram Guy:

 

I have a CMX512-3200 DIMM Module and it's having problems again!

 

This is the third time I have problems with Corsair Memory Modules, the details of the last two times are in forum: CMX512-3200C2.5 Failing MemTest86+ In my System: http://www.houseofhelp.com/forums/showthread.php?p=160306

 

The problem began some days ago when I was playing Prince of Persia: Warrior Within and Unreal Tournament 2004, my computer freezes, the screen went black and strange noises came from the speakers, yesterday I turn on my computer and after booting Windows I tried to open Internet Explorer, suddenly the computer reboot and never booted again, beeps from the speaker and the MoBo’s LEDs shows a memory problem, after that I removed the DIMM and tried another one and the computer booted correctly, after that I tried with another DIMM (256MB) and the CMX512 but the memory test shows only 256MB. Also tried to put the DIMM in every socket but didn’t work! After that I tried the DIMM in other computer and again didn’t work.

 

I need to RMA it. Hope this time the replacement module will work well because the time I spend sending it to your company and the cost of the last two international shipments (~US$10 each) plus this new shipment (another US$10) becoming almost half the price of a new module.

 

A short system brief:

 

Athlon Xp 2400+

Msi KT880 Delta

120gb 7200rpm Maxtor HDD

Ati Radeon 8500 128mb.

Sound Blaster Audigy Gamer

 

Memory timing used: 3.3.3.8

One Month ago I updated the BIOS from 1.5 to 1.9, after that I loaded the BIOS "Optimized defaults”, later I changed some settings:

 

Advanced Chipset Features:

 

Configure DRAM Timing by SPD= Manual

SDRAM CAS# latency= 2.5

SDRAM Bank Interleave= Disabled = Default

Precharge to active (Trp)= 3t

Active to Precharge (tras)= 8t

Active to CMD (trcd)= 3t

REF to ACT/REF to REF (trfc)= 15t = Default

DRAM Command Rate = 2t command = Default

Vlink 8X Supported = Default = Enabled

 

Cell Menu:

 

Memory Voltage = 2.7V

High Performance Mode = Manual = Default

Dynamic Overclocking = Disabled

CPU Voltage = 1.65V

CPU FSB Frequency = 133

CPU Ratio = AUTO

DDR Frequency = By SPD = Default

CPU Clock = 2000 MHz

 

Other settings= Default.

 

After things go wrong (black screen, reboots, etc.) I tried these settings:

 

Advanced Chipset Features:

 

Configure DRAM Timing by SPD= Auto = Default

Vlink 8X Supported = Default = Enabled

 

Cell Menu:

 

Memory Voltage = 2.6V = Default

CPU FSB Frequency = 133

CPU Ratio = AUTO

DDR Frequency = By SPD = Default

CPU Clock = 2000 MHz

High Performance Mode = Manual = Default

Dynamic Overclocking = Disabled

CPU Voltage = 1.65V

 

I ran Memtest86+ every time  First pass - 0 errors, Second Pass – 0 errors.

Please try these settings.

Advanced Chipset Features:

 

Configure DRAM Timing by SPD

 

Memory Voltage = 2.7V

High Performance Mode = Manual = Default

Dynamic Overclocking = Disabled

CPU FSB Frequency = 133

CPU Ratio = AUTO

DDR Frequency = DDR333

CPU Clock = 2000 MHz

 

Other settings= Default.

 

 

Then test the modules with http://www.memtest.org

I can’t try these settings because the Memory Module is “dead”, the module doesn't work in my PC anymore. I also tried the Module in another computer but it doesn’t work.

 

When I put the module in any socket and try to turn on the PC, the screen is black and the speaker beeps continuously, after I remove this module and put another, the PC works fine.

 

I also tried a BIOS reset (with the “Clear CMOS Jumper”) but the module didn’t work with the default CMOS settings.
