Help-how do i do this if my computer won't pass POST


Recommended Posts

I asked for help because my computer wouldn't pass POST. the Led display on the striker extreme indicated "Mem Test" Originally, I was asked to request an RMA. I did so.

This is what I got in response


"Please make sure that you have the latest bios for your MB and then load optimized defaults and set the Dim Voltage to 2.4 volts and then set the timings to 3-4-3-9 (CAS-tRCD-tRP-tRAS) and then test the modules one at a time with http://www.memtest.org! Please allow memtest to run 2-3 passes on each module. If you still get errors, we will be happy to replace them! However, if you get errors with both modules that would suggest some other problem and I would test them in another system or MB to be sure"


I am not a computer whiz and have no idea how to do this is the computer won't even get to the bios but fails in the post. Can I have a bit of help please

The problem very likely is that your motherboard is setting too low a voltage for your very high end memory. Your memory needs 2.4V to run at it's spec. Get a cheap piece of 512mb value ddr2 dram and remove the 6400C3's. Insert the value ddr2 dram and restart the system. Enter the BIOS and use these settings.


Multiplier = 9

FSB = 266

DRAM = Unlinked and set to 800Mhz


Memory Timing


FSB - Memory Clock Mode: Unlinked

CPU FSB: 266

CPU Multi: 9

DDR FSB: 800

tCL: 3

tRCD: 4

tRP: 3

tRAS: 9

Advanced Memory Settings

tRRD: Auto

tRC: Auto

tWR: Auto

tWTR: Auto

tREF: Auto

Async Latency: Auto



CPU Spread Spectrum: Enabled

PCIE Spread Spectrum: Enabled

MCP PCIE Spread Spectrum: Enabled

SATA Spread Spectrum: Enabled

LDT Spread Spectrum: Enabled


CPU Internal Thermal Control: Enabled

Limit CPUID MaxVal: Enabled

Enhanced C1 (C1E): Enabled

Execute Disable Bit: Enabled

Virtualization Technology: Enabled

Enhanced Intel Speedstep Tech: Enabled

LDT Frequency: 5x


PCIEX16_1 Frequency (Mhz): Auto

PCIEX16_2 Frequency (Mhz): Auto

PCIEX16_3 Frequency (Mhz): Auto

SPP<->MCP Ref Clock, Mhz: Auto



Vcore = Auto

Vdimm (DRAM Voltage) = 2.4v

1.2v HT: Auto

NB Vcore: Auto

SB Vcore: Auto



Results? If your system boots up, then:


Download Memtest from
and extract the ISO image. Burn the ISO image to an optical disk. Boot to the Optical drive and allow for 2 full passes.

If you are unable to get into the BIOS and do not have another system to test the modules on, then let's get them or it replaced. Please follow the link in my signature “I think I have a bad part! Or “Tech Support Express” and we will be happy to replace them or it, please note that you are posting from the forum!

I just wanted to say thank you to all who replyed. I was able to have twin Corsair 8500 dominator memory post on my computer. This led me to put the 6400 memory in another computer and sure enough there was a post failure. Tried a single stick and it went through post. Tried the other one solo and it failed. I have taken the ram guys steps and was issued an RMA. I will send it out this Saturday. You folks are great and again thanks
