CPU and Motherboard Compatible Question

[SundayRoast28]

Recently I posted for help In regards to a problem of Very low frames per second while playing all games.A guy on here solved my problem by saying that my CPU (9590FX) was not compatible with my motherboard (GIGABYTE 78LMT-USB3) and that was which was causing the problem. Anyway my question is every time I search online about this problem people are saying that if the two are not compatible then it will just not turn on. The question is why does mine still turn on and work etc like Normal if it's not compatible?

It actually isn't compatible I looked on the list.

It's not compatible due to TDP. That CPU has a monster TDP of 220W (I think, at the very least it's over 200). You need a motherboard that supports that gigantic TDP to your CPU otherwise it won't be able to harness all of the power that is needed. You have a V8 in your system, but only enough gas for 6. Not a perfect analogy, but it's essentially the same thing. Not enough juice.

It supports the chip in that it physically can work, but the motherboard just can't handle the CPU under any type of heavy load. The motherboard has 4 power phases only (more is better) and supports chips up to 125W. A 220W chip like yours is going to cause the motherboards VRM to throttle down and thereby reduce performance. If the motherboard tried to run that chip at its full potential, it would overheat and man we hope it'd shut down to save its life.

If you're typing a Word document, yeah it'll all be fine. But put it under any type of load, and the motherboard will become unstable and it will downclock the CPU in order to lighten the load. You need a high-end motherboard and cooler with this chip. Both combined should be costing $250 at least.

It's usually a wattage thing. The board is not built to supply the amount of wattage the CPU can require. When you turn on the computer, the CPU is using just a little power, it sounds like when you push the CPU, the voltage does not rise to needed levels and the CPU is hindered. The motherboard is possibly otherwise compatible, but will likely end up killing the motherboard, pushing the wattage limits.

Thank you so much guys for you're response, iv asked this question to another guy but just want a second opinion. Will I be able to still play games like world of Warcraft for another two weeks till I can pick up a compatible CPU?

If all you're playing is WoW, you should be alright. Honestly, instead of picking up a new CPU I'd get another motherboard. Either one will work out to be the same price, but you already dropped $200+ on the CPU. A motherboard that supports it should only be around $100-150. AMD motherboards (good motherboards) ain't exactly expensive anymore.

How comes my world of Warcraft runs smooth (only game that does) would it be because it runs off my GTX760 and not the CPU?

No, MMOs are more CPU intensive than GPU intensive, but it's also not all that demanding of a game. What are your core clocks dipping to instead of the advertised 4.7?

Sorry how would I find that information?


I'm googling il let you know lol

From looking at CPU performance in my task manager settings it says that max speed is 4.00GhZ but when I'm just walking in WoW it's staying at speed 1.32GHz doesn't change which is less the half the speed of the CPU.

Guess I'm pretty lucky I didn't damage any of my Components because I completed Doom the other day before I knew all this lol

What FPS are getting in WoW when it's sitting that low? You said you weren't having an issue with it.
