Gigabyte GA-78LMT-S2 underclocking my processor FX 8350

Hello, I recently had some issues with my PC, and had to change my motherboard to the Gigabyte GA-78LMT-S2. I used to get black screens when using my previous motherboard and after troubleshooting through all options, I changed the motherboard, got a used one as I was on quite a budget and I simply wanted to make my PC running again and not make any unnecessary upgrades.

Anyways, the GA-78LMT-S2 keeps giving me the error message on post as follows

"The current system does not support the CPU.
If wish to continue, the CPU will be
underclocked to maintain system stability."


I thought that updating the bios would solve the problem. It didn't. It keeps up with the same message. My motherboard is rev. 1.2. It was easily identified from the color scheme itself, so I don't believe that I used the wrong bios update file.

I also checked the CPU compatibility list on the gigabyte site, and it seems my specific motherboard wasn't listed there.

I do have a feeling that I maybe stuck at my underclocked CPU until my future upgrade, but would anyone know how would I be able to return my clock speeds to the usual? Or atleast stop the error message from popping on POST?

Thank You.

As you already know, the FX-8350 is not on the CPU Support List. AMD FX CPUs with TDP (Thermal Design Power) over 95 watts are not supported. The FX-8350 has a TDP of 125 watts.

The Thermal Design Power (TDP) is the average maximum power a processor can dissipate while running commercially available software. TDP is primarily used as a guideline for manufacturers of thermal solutions (heatsinks/fans, etc) which tells them how much heat their solution should dissipate.

The motherboard may fail in the future from the excess heat. This kind of damage is not covered by warranty. It is know as customer induced damage. Since, that would be hard to prove Gigabyte seems to have added a safeguard to limit the power and the amount of heat it...

The amount of TDP is too damn high. Thank you. For some time I though there might be some software issue. I just didn't realise that motherboards have a TDP safe limit as well. Thanks for clearing that up.

One can not simply bypass cap, its made to support up to 95W processors. Putting 125W and doing a bypass witch is not possible would kill the motherboard since the parts on it are not made to support higher power.

It's not an arbitrary limitation, but one determined by the very real limitations of the parts on the motherboard. It's simply a budget motherboard that's not suited to running 125W CPUs.
