Replied to that, with a better explanation on why. Really sad, indeed :/

Now that I understand what happened I'm surprised it lasted almost a year. At least my new mobo will actually allow me to try overclocking.

Were you folding throughout that year, or just lately?

post #1055 of 1100
Just started up again, I was folding earlier but the program stopped working. I reinstalled it last week or so. I've been getting hassled by my family for wasting electricity and stuff so I'm just going to let it lay low until I blow the joint in a few years.

It appears that MSI has taken on a first with its 970A-G46 board and has added a VRM over-voltage throttling technique. The first point that made me aware of this was a reviewer on Newegg:

 

 

While it is not clear with this review whether it is really over-voltage throttling or another thing called Advanced Power Management (APM - I think it has to do with the chip temperature more than the VRMs and happens on all boards with FX processors), I took to the MSI 970A-G46 webpage and found that a BIOS update released in December added an "OVT protection function". The single VRM failure with the 8-core on the 970A-G46 was recorded in September, but there have been no failures since.

 

For the first time, I am marking down a low-end MSI AMD board as safe to use - however, I will also be marking its limited capacity with 8-core processors.

This is my first post here and it is a sad post.
My msi died two days after a short test in blender rendering a hd video.
after reading the forum, I turned off the 12v power processor and voila .... the motherboard came to life.
It seems more a fault of the vrm on octacore cpu, now without any overclocking.
What to do?
Usually the mobo for RMA and ride my pc with a refurbished card?(msi gave an option to take one refurbished 990FX and pay the diference)
Buy one msi 990FX? one gigabyte or asus?
Or would it be better to abandon my octacore and mount a intel?
PC components:
msi 970A - g46 (deceased)
fx 8120 (survived?)
2 X 4Gb corsair vengence
