I own an ASUS M3A, with an Phenom 9750 mounted on it. I bought an X2 5400 local and went to test it. First flick of switch fans spun then shut down. Second attempt to start be damned if it never burned up a MOSFET on power rail, assuming it is power rail MOSFET that burnt (close to 24 pin plug??). I sent the board to ASUS their wonderful RMA dept took 20 working days to return it as they had lost it BUT sent RUSH delivery. In the mean time I had replaced the board w/ a better one ASUS M3N78Pro.
I am thinking should I try the CPU on the same board again??? As far as I am concerned I had done nothing wrong (everything was plugged in, I never reset CMOS as the board should or recognized a different CPU and posted with default values.)
ANY feedback would be much appreciated. As to why this would of happened ... or other experiences similar.
Sounds like it had to be some kind of user error to me. A cpu with a properly installed cooler should never have something like that happen. Then again maybe it is the rare occasion where there was faulty cpu.
Yes, if the CPU is in short (short circuit, which means it may be burnt/dead) it may cause (I reapeat, *MAY* cause) your system to die (psu/mobo etc), but if the power supply is good enough, it may have a short circuit protection that will detect the problem on its power-good phase and just won't turn on.
Even if I can recommend a good power supply to anyone, I always pop the CPUs on low cost motherboards like asrocks before I install them on the final PC, but never happened so I may be just paranoid.
Oh and by the way, I love Nforce, what do you think about the M3N with your phenom compared to the M3A?
I've been a long time nforce+Athlon user, I had nforce, nforce 2, nforce 2 ultra, nforce 3 250, nforce 4, and nforce 560. Not sure if jumping to Nforce 8200/750... or jumping to ATI 790GX instead, as they have better onboard graphics performance.
