How to stabilize CPU?

[ww1superstar]

I have a AMD FX9590 processor, and I will say that this CPU was a mistake to buy. It is high power but it VERY unstable and causes a ton of heat (under control though) and will freeze under high loads. Is their any way to stabilize it so it wont freeze after 10 minutes playing a game on high power? I read somewhere about disabling cores 1 and 6 but I dont know how to do that either.

Please list all your PC parts, mobo, PSU, cooler ect.
How looks CPU temps ?

If it freezes under high loads, the heat may not actually be "controlled". What's the temperature under load? What kinds of programs/games do you run? What kind of heatsink or water cooling solution do you use?

If its freezing under high loads the heat is not under control. Something is overheating. What motherboard are you running? Are you using a watercooler (either the stock or an aftermarket one?)

If you are gonna disable 2 cores you may as well sell it and buy an FX-8370.

OK so you posted another thread about your PSU, you are running the incorrect motherboard the M5A99X EVO R2 for that CPU. That chip requires 220 watts to run, and only certain motherboards can handle it. The motherboard you have cannot handle that chip and no matter what you do its never going to run right. Switch that board out for something that can handle 220w TDP such as the ASUS Crosshair V or you are just wasting money.

Hi,

I've got an FX-9590 working on the M5A99X EVO R2.0 but it took quite a bit of trial and error with the BIOS settings related to voltage regulators, etc (go for the most aggressive settings to start with then tweak from there) and even now it occasionally locks up, but I've noticed that it seems more likely to do it when idle than when busy, which suggests a power management issue. (I could try locking the core speed at 5GHz or something, I suppose.)

As has been pointed out, heat is also a potential issue unless you've got seriously good cooling and even then you're likely to find that your room temperature could make the difference between stable and unstable. What cooler are you using and what temperatures does your CPU run at when idle and when busy? (Mine's at 33°C at the moment, having been mostly idle all evening in a fairly warm room. It normally gets to about 65°C when fully-utilised for an extended period but I saw it hit 74°C on a particularly hot day a month or so ago. I'm using big air - a Prolimatech Genesis with two 140mm fans, having been unimpressed with the comparative performance, cost and noise level of water coolers.)

Given that it's not supposed to work on that board, though, it's probably a case of "your mileage may vary"

If you have heat issues undervolting it (as the board maxes at 140) then that is pretty bad, Usually undervolting allows a processor to run cooler. Also undervolting it you are losing a significant amount of power.

As you said, it works, but only just. YMMV

Perhaps I should try undervolting it - I'm running it at full voltage (and therefore power usage) currently. The board seems to be able to deliver enough power, though - I've seen the on-chip power monitor read as high as 219.06W when the CPU has been maxed-out, which is consistent with the 220W rated TDP.

It is a 990FX board with an 8 +1 power phase so I have no doubt it will be able to physically do it (theres no like switch at 140w that says "shut off), however maintaining it stably is the problem and what its not rated for. At this point you own it you may as well give it a try, it should significantly lower the power draw. That said you may lose a lot more performance than just swapping it for the 8370. But give it a shot, if it does what you want it to you're good.
