Upgraded to AMD FX-8350 from Phenom II 1090T and now freezes & crashes

I previously had a Phenom II X6 1090T CPU and recently installed the AMD FX 8350 CPU with the same PC build and set up. Since the installation, I'm getting random freezes during varying times while logged in to the OS. Sometimes under very light load conditions -- sometimes all I have is a browser open with nothing else, and it freezes. Sometimes there's a blue screen and the PC restarts (sorry, I haven't had a chance to screen capture).

Any help or tips that anyone could provide would be extremely helpful. I'm really not looking to spend loads of money on upgrades at the moment, but if I need to change out one thing (like a PSU), I'll do that. If I have to spend hundreds of dollars on upgrades to work with the FX 8350, I'll probably go back to the 1090T and wait a few more years before a new build.

For the most part, I am a beginner at any type of overclocking -- so any feedback that includes references to instructions or configuration techniques (or youtube videos) would be very helpful. I also don't know all the stuff I should provide for this type of question, so please let me know what to include and I'll do my best.

Here's my set up:

CPU: AMD FX-9350 (previously Phenom II X6 1090T)
Motherboard: Gigabyte GA-970A-D3
BIOS: F13b
Case: Antec Nine Hundred
Power Supply: OCZ: MOdXStream Pro Series 600 Watt - OCZ600MXSP
Memory: 16 GB Corsair Memory Vengeance 16 Quad Channel Kit DDR3 1600 MHz (PC3 12800)
OS: Windows 10 64 bit
Graphic: Radeon RX 480

Before I bought the FX 8350, I checked that it was compatible with my motherboard, but the more I try to find answers on this topic, the more I'm unsure. I've seen some success stories with lowering voltage on some set ups, but nothing matches my circumstances exactly (and I don't know how to lower voltage).

Not sure if this stuff helps:

The revision thing is what makes me cautious when anyone states they have a Gigabyte motherboard, or even when I consider one (don't see the revision as part of the item info).

I have no experience in it, but the only thing which comes to mind is to underclock the CPU (other than getting a compatible CPU). Basically, the idea is to manually decrease the amount of voltage sent to the CPU in order to get some stability.
FX-9350 or FX-8350? And which revision of the motherboard? Neither CPU show up on the supported CPU list of rev.1.0, 1.1 and 1.2; only rev.1.3 and above support the FX-8350:

https://www.gigabyte.com/Motherboard/GA-970A-D3-rev-10-11#support-cpu

Incompatibility would be the simplest explanation (though not necessarily the correct one). I would suggest double checking which revision of the motherboard you have just to eliminate this possibility.

I'm not certain if you have overclocked, or just interested, but I would also suggest removing any overclock for the time being for stability issues. An unstable overclock can cause the issues you've mentioned.

Hopefully someone who knows their stuff will be along shortly.

 
That motherboard's QVL doesn't list the 125w FX-8350, only the reduced voltage 95w FX-8320E and FX-8370E when using the latest f13b BIOS.

It does list other 125w CPUs including your 1090T, so perhaps the issue is the VRM can't stabilize VID fast enough when switching between high and low clocks on Piledriver. In that case you could go into the Advanced BIOS Features and disable Cool'n'Quiet, so it will run at full speed all of the time.

It's the FX-8350 -- sorry about the typo.

You might be onto something regarding the motherboard rev. I have rev 1.0 and I must've checked the latest when I previously looked at the compatibility.

Crap. I may have assumed that the FX-8350 was going to work because it was 125w just like my 1090T, but I have confirmed that my motherboard rev (I have rev 1.0) doesn't show FX-8350 as being compatible.

I turned off Cool'n'Quiet, but it will still freeze on occasion. I also haven't done any overclocking at this point, but if you have suggestions for modifying the voltage (or something) to help here, that would be helpful. I don't know where to start.

I would try just raising the core voltage first. Only if it couldn't find stability by >1.45v would I resort to underclocking, as it's slow enough already. Overclocking it on that board is out of the question.

The Piledrivers are perfectly safe up to at least 1.5v and one of them (the FX-9590) even came with a max VID of 1.5375v. It's just that temperatures get out of hand and become more trouble than it's worth vs. just dropping the clocks.
