Determined to be faulty

After returning memory and motherboard PBTech have determined that my CPU is causing the instability. This was by far the.most expensive part of my PC build, so am very disappointed in this product.

To keep it short, if you are looking for the most FPS in games, don't buy this, the 9800X3D is cheaper and faster for games, but if you use your PC for lots of productivity stuff (eg video/photo editing) and also want pretty decent gaming performance, you could consider this CPU.

Great introduction to the B1851

This CPU runs well and handles games effectively. It may not run the same frames as the latest AMD beast, but I did not get this solely for the gaming frames. That being said, it runs ultra with more frames than I could possibly need. I run video editing software, browsers, games, communication apps and more at one time, so having the extra cores certainly helps with this. I am yet to see more than 40% usage with my current build, so it is handling very well.
