Please help! CPU+MOTHERBOARD=problem

[A Bunch of Random Letters]

Hi, I dont have much money and I wanted to custom build my pc. So I got all the parts used. Now I got the asrock 970m Pro3... The box says FX series, FX 9 series, 8 core compatible. Now when I put my fx 9590 in and put it all together today, it shows a black screen and it says a couple things but then it says cpu not compatible.

How is it possible for a motherboard made for a specific cpu to not even work with it!

Please help me fix this, thanks in advance.

I'm nit sure the power phases and delivery of that board will.manage the 9590. Be best selling that chip ans drop in a 8350. The fx9 are rather pointless...not much above a fx8 in performance and ridiculous power consumption that only the best mobos can cope with.

That's not a good match. That board is rated with 4+1 power phases and for cpu's up to 140w tdp, the fx 9590 is a 220w tdp cpu. I'm not sure why it would say 9 series unless they mean 9 as in 970 chipset. For cpu's like the fx 8350 or others with a tdp of 125w it recommends a top down air cooler to help cool the vrm. That cpu requires a high end board with something more along the lines of 8+2 power phases with larger vrm heatsinks and the capability to support that kind of tdp and power draw. It's likely shutting down to prevent cooking the vrm on that board.

In addition you need a higher end psu, something in the 800-1000w range and solid cooling (aio liquid, not a low end air cooler).

If you read the supported cpu list the 9590 is not listed. None of the fx 9xxx are listed, I think you misunderstood the package advertisement. It's also not uncommon for several lower end amd board to claim they work with a given cpu like an fx 8350 and have issues due to weak vrm and power delivery.

I'd agree with burgessanthony, you're likely better off to ditch the 9590. You'd be looking at something more suitable to run it on like an asus crosshair V formula z (around $216), asrock 990fx extreme 9 (around $168) etc. It's more or less a highly overclocked fx 8350 and even getting a 9590 to run stable at stock can be difficult. Many users end up underclocking them to get them stable, sort of defeats the point. An 8350 is less expensive and when overclocked stably will give about the same performance.

Though I wouldn't recommend overclocking much on that motherboard even with an 8350. You're still looking at an 8 core cpu with a fairly high power draw under load compared to other cpu's. That motherboard would likely be better suited to an fx 6350. By the time you invest in all the parts to properly run a 9590 you could just buy an i7 and end up with a stronger better performing and more power efficient pc. Just a comparison to put it into perspective.

That's being generous, the price could easily be lowered further going with an i7 6700 and an h170 board with a cheaper cooler. Only around $30 difference for the latest unlocked i7 with a z series board capable of overclocking vs the fx 9590.

wow thats kinda bs. Thanks for the answers. Would I be better off with an 8350 on the same board? That i7 build is a great idea, but i already purchased the parts 🙁

The FX-8350 is roughly equivalent to a Core i3 6100, which draws 1/3 the power and you could pair with a $50 H110 board. The FX is not a bad CPU if you already have an otherwise complete system you can drop it in, but I absolutely would not recommend anyone build a system from scratch with a 4 year old FX CPU in 2016. This includes the FX-9xxx CPUs, which are arguably the worst CPUs AMD has ever made.
