CPU

AMD FX-8320 Eight-Core Processor Black Edition AM3+ FD8320FRHKBOX

Motherboard 

MSI 890FXA-GD70 (BIOS version 1.15 7640v1F)

Memory

Corsair Vengeance Blue 8 GB (2X4 GB) PC3-12800 1600mHz DDR3 240-Pin SDRAM Dual Channel Memory Kit CMZ8GX3M2A1600C9B

Power Supply

Corsair AX1200 1200-watt power suppy

OS

Windows 8 64bit

 

We are replacing existing AMD CPU with faster CPU (older cpu is the AMD Athlon II X2 250 Regor 3.0GHz Socket AM3 65W Dual-Core Desktop Processor ADX250OCGMBOX).  After replacing the CPU with the new CPU system will post but not boot.  Windows 8 immediately crashes indicating checksum failures.  

 

We have tried swapping out the hard drive and re-installing Windows 8 on a different hard drive but the installation fails shortly into the install.

 

We have tried repairing the operating system but that again fails fairly quickly.

 

We checked MSI's website to ensure compatibility and this site (http://us.msi.com/product/mb/890FXA-GD70.html#?div=CPUSupport) and it indicates the FX-8320 is supported with the 7640v1F bios which we have installed.

 

As far as bios settings go, we have tried the fail safe defaults and factory defaults.

 

So the CPU seems to be partially functional at least but crashy.

 

Case has plenty of ventilation and there really is no time to build up heat before the crashing occurs anyways.

 

When we put the old CPU back in everything works great 100%.

That motherboard had some option to mess around with "Unlock CPU Core" technology you might check those settings.

Worse case is a bad CPU, so if you have enough Thermal paste you might put the old one backin.

The specs say AM3+ is supported so that all I got.
