[SOLVED] Installed new CPU, computer now recognizing a CPU I never had (and running slower)

[tokum13]

MoBO: Pegatron 2ACF
Ram: 16 gb
Graphics Card: NVIDIA GEForce GTX 990
OS: Windows 10 (on a solid state)
Old CPU: AMD A6 3600; New CPU: A8 3600; CPU reported: A4 3300

I've been in the process of upgrading my PC. Virtually every thing is new except the MoBo. The last thing was the CPU. I switched the new A8 out with the A6 and fired it up. The computer starts and operates significantly slower and Device Manager and CPU-Z both report my CPU is an A4. I never had an A4.... I uninstalled the processor drivers in device manager, and restarted my computer. It just got the A4 drivers all over again.

I'm really at a loss as to what to do. I'm not tech savvy and have been learning this stuff on the fly, but I hit a road end. The only other suggest I found was to update my MoBo Bios but I can't find out where I go to actually get the update? AMD's website said something about searching for it online and then downloading the update onto a flashdrive and starting up my computer in Bios. Does this make sense? Could this be the problem? The problem seems to be more than a detection problem, as it is quite clearly running slower. This would make sense since the drivers of the A4 are equipped to run 2 core when the A8 should be four core. Any thoughts?

Where did you get the CPU from? Is it a reliable source? I doubt that a BIOS update will change what CPU you actually got. I think you need to download the BIOS from HP's support and downloads section. You need a serial number of the product for that.

One of the many problems with prebuilt motherboards is that there's always the possibility that it doesn't actually support an A8-3800. And expectedly, the documentation for this motherboard is quite poor.

Does the original CPU still work? If you're not using the integrated graphics, they're pretty much the same CPU clocked a little higher and it's doubtful it'll make a meaningful difference in most things given how old both these entry-level APUs are. Not quite sure what the GPU you're using is; there's no GTX 990.
