Twin2X2048-5400C4 - not working on 2 motherboards

Hello,

In may 2007 i composed a new computer. I'v buyed Twin2X2048-5400C4 with a motherboard Gigabyte GA-M55S-S3.

I'm not a tweaker so all my values are default or automatic.

It worked good till last week. Suddenly a BSOD with the message NON_PAGED_AREA. Rebooting didn't worked. The computer even crashed during booting of the BIOS. So I flashed my BIOS with the latest BIOS but that didn't helped. I started to search and i found this board. :sunglasse

I've read some topics from the RamGuy and i started to try the memtest. The first module i tested was error free. The second module i tested in the same slot give 11000 errors. I was thinking case closed and contacted my local dealer. He swapped the 2 modules .

Now i have installed them and it gives the BSOD again. :eek:

As a test i have put the modules in the computer of my wife. The computer have a motherboard Asrock AM2NF3 and it gave immediatly a BSOD during booting. After this fatal boot it stays dead. rebooting didn't worked. BIOS didn't get loaded. So I placed the original module back ( Cmos ) and her computer works again. Now i have tested the new modules in this computer and again 1 module is OK but the second give errors again.

What can i do? I'm getting really sick of it. :(:

Thank you for your advice :cool:

Please make sure that you have the latest Bios version

Like i have said in my first post: i already updated the BIOS with the newest version.

set the Dim Voltage to 2.0 volts (+.2 Volts W/Giga-Byte)

I have done this at this moment.

then set the timings manually to the tested settings for the specific module you have, or if you have Value Select "BY SPD"

I can't find this in the BIOS settings. Could it have another name?

And where can i find the values that i have to enter?
