Here is my E5430
Spent RM110 for the mod sticker and CPU

Learnt from this link
http://www.overclock.net/t/1384920/good-ne...775-motherboard
need to update the cpu microcode too

Compatible Chipset:
G31 and above (some 965chipset able to do so), X38 and X48 most of the user say cannot

It is quite simple but i am still wondering the stability of the cpu. So far no shutsdown or bsod. FATAL ERROR on Prime95 when i select maximum heat test and blend test (Tests required ram). but small fft test ran for 5 hours no problem.

:UPDATE:
Reseat ram and cpu, able to pass 1st test, not like previous 1st test fatal error

:MORE UPDATE:
2nd test CPU 3 fail, [on max heat test], need to run small FFT test for the last time to chesck whether is CPU fail or RAM fail or MOBO fail rclxub.gif

:3rd update:
Tested small fft test for 15hours. No errors. I will run mem test again and bump the ram voltage.

Motherboard memory controller is the culpurit. CPU is fine.
