My MSI K8NGM2-IL  mobo had Transcend  256mb ddr400 ram 2.5-3-3-8, model no. TS32MLD64VF working fine.  I transferred the memory to my Intel 915gav mobo already having Hynix ddr400 3.0-3-3-8. After few hours of system up, it gave BSOD with  PFN_LIST_ERROR.
Now the system shows weird errors at boot up. It auto-restarts past bios.
Sometimes locks at bios screen. Sometimes boots and before logon screen gives different bsods each time with following different errors  
 
Bad_Pool_header   0x00000019
IRQL_Not_less_or_equal   0x000000A
Bios is not ACPI compliant  0x000000A5
0xC0000005
C000021A  Session manager error  0xC00002bc
0x0000008E (0xC00005,.......)  win2k.sys error address bf801ceb base at BF800000 Datestamp 48025T2a
 
These errors are indeed memory related but the transcend stick is working fine on msi mobo with no memtest error.
Also Intel mobo memory slots are not faulty, tried with other ram sticks.
It has 4 slots 2 each of 2.5v and other two of 2.6v. None seem to work.
Once with relaxed timing could boot into windows but withing 5 mins gave back bsod. This single transcend stick when used alone can't post to bios screen even. Only the cpu fan rotates at high load.
 
Please help.
 
 
 

Don't mix the memory
