Bad memory module?


Recommended Posts

Hi-

 

I've got a brand new Soyo P4I865PE Plus Dragon 2 V1.0, and 2 new sticks of Corsair VS256MB400 RAM, in slots 1 and 3. I've been getting multiple Stop Codes in WinXP, and in researching each, found that they point to possible problems with RAM. I'm getting these messages on a clean install of WinXP Pro, with nothing but my video card and DVD-ROM drive connected (and hard drive, of course :) ). I've tried the default and optimized BIOS settings.

 

I haven't run memtest86 separately on each stick of RAM, but will tonight. I noticed that you give suggested BIOS settings, and thought you might give me some suggestions I might try in determining whether one (or both, I suppose) of my memory sticks are bad (or if its something else entirely). Thanks in advance.

 

P.S. - Don't know if these will help, but here are the stop codes I've been getting:

 

0x00000050 (Page Fault in Nonpaged Area)

0x0000004e (PFN List Corrupt)

0x0000008e (No description came with this one)

I would make sure that you have the latest bios and then load setup defaults and set the Dim Voltage to 2.7X Volts and then test the modules one at a time with http://www.memtest.org to make sure one is not failing. If you do find you have a failing module, please follow the link in my signature “I think I have a bad part!” and we will be happy to replace them or it!

Hello again-

 

I tested each stick of memory separately with memtest, and received no errors (3 or so passes). I tried using only one stick of memory at a time in my computer, and didn't receive the errors I had been getting. I placed both sticks back in slots 1 and 3, and quickly received stop code errors. I tried placing the sticks in slots 2 and 3, and didn't receive those errors in the time I used it.

 

I'm wondering if my two sticks of memory just don't play together well. I'd like to take advantange of DDR, but as you can see, I'm getting errors when the sticks are in the appropriate slots. Also, the BIOS for this mobo isn't very comprehensive; I don't see a way to adjust my dim voltage. The BIOS on my old mobo gave me a lot more options.

 

Finally, I wanted to reiterate that I didn't buy a 512MB (2x256) "kit". I bought two identical 256MB modules. Would that make a difference?

 

Any suggestions? I appreciate your help.

Please set the following BIOS settings and see if this will do it:

VS256MB400

Soyo Combo Features/Advance Tune Up Setting

CPU Freq: 200 MHz (800 FSB)

Memory Frequency: 200

CPU/DRAM ratio: 1:1

Memory Timing: User Define

SDRAM CAS Latency: 2.5T

SDRAM RAS to CAS Delay (tRCD): 3T

SDRAM Row Precharge (tRP): 3T

SDRAM Active to Precharge Delay (tRAS): 8T

DDR Reference Voltage: 2.7 Volts

AGP Voltage: Default *unless you have ATI (9200 or 9600) or NVIDIA (5200 or 5700) then 1.6 Volts suggested!*

All other settings are motherboards defaults

Then please test them one at a time with http://www.memtest.org and let’s make sure it's not some other issue! I would run the test for at least 2-3 passes to be sure!
