Question FX-9590 - buggy upgrade

Hi!

I've just made a massive upgrade for one of the youngsters in the family. I like to press the limits of older generation computer gear, and the plan is to go high end for a AMD FX-rig, and I got hold of an FX-9590 CPU. He had a FX-6300, so this should keep him going with an ok improvement in gaming I believe...

The problem: The comuter starts up ok with the "new" CPU, but the system halts after 1-2 minutes . It runs ok with an FX-8350.

For the time being, the rig might have a bit low specifications (?) for running the 9590: 700W power supply and a Corsair H60 water cooler. Is this lightly to be the problem, or is it more lightly to be a buggy "eBay" CPU?

The motherboard is an Asus Sabertooth 990FX Gen3 R2.0 (Newest Bios)
It runs 32GB 2133MHz RAM

The FX-8350 might be a better choice for the upgrade either way?

It's not a massive upgrade. The 9xxx chips are nothing more than massively OC'd 8350. They are given so much voltage to reach the clock speeds that they go from 125W CPUs to 200W+. They need much better cooling than a H60 can handle, and ~30% of your "700W" PSU is going just to the CPU. (I'm pretty sure that "700W" isn't really putting out 700W.) The boards can barely run them due to the 200W overloading the VRMs on the board. Better cooling on the CPU and active cooling on the VRMs of the board might get you there. Downclocking the CPU to 8350 speeds should help as well. But honestly a massive upgrade is moving to a newer system. FX is dead. I never would have "upgraded" him off that 6300. It games as well as the 8350. The only real upgrade is to Core or Ryzen.

I have both of those CPU's and have run them both on a M5A99FX Pro R2.0 board. I've found that the thermals have to be just right for the FX 9590 or you will have problems.....That H60 may not be able to meet the thermal demand imposed on it by the 9590. The Noctua CPU Cooler NH-D15 is what I use...Personally the 8350 works just fine for the some of the gaming I do on lower settings...I like to do the same thing with older hardware

Yes, I know, but It can be done a bit step by step. The rig here is set up with 2 x R7970 in crossfire, but with a high end FX-CPU, we might be able to invest in a newer GPU that still holds in a new Ryzen rig later. I have recommended to try the AMD RX 5700

I have done so for many years, since the serie-A/Pentium 3/4 times, out of necessity...have had four kids, all in it for gaming, and I'm not loaded with means. Now they all have fled the nest, but when it comes to building computers, they still trust me for saving them for some costs...

We landed on the 8350...and It's running smoothly. I guess I get a report for the gaming capacity tomorrow...

I might save the 9590 for a backup rig...I could like to try to build a full water-cooled rig some day...for fun :)
 
I'd dump it on Ebay. Take anything you can get for it.

The 8320/50 aren't horrible CPUs. Most games they do just fine on. But there are enough exceptions that I always avoided FX. I want a system I know it can handle anything I throw at it. I don't want to worry.

If so, I'd rather give it away for free...though it might be buggy :)

I've purchased a few Dell servers at our local Goodwill and upgraded as far as I could just to see how ell they performed at there best.....Precision 690's and 490's also an old mac pro I stuck a couple of xeon 5365's in....ran pretty good triple boot with Linux mint, Window's 10 and osx lion ....for fun :)
 
The H60 is a 140w cooler. The FX 9590 is a 220w cpu. You couldn't keep that thing cool at anything over idle.

When first introduced, AMD actually went as far as including as a stock cooler a H80i equivalent aio. That lasted about a year until AMD finally figured out that a) the cooler was still massively insufficient and b) almost every cpu sold ended up with a stock AMD AIO on sale on eBay as ppl tried to recover a little bit of cash back after not only buying a much larger 280mm AIO, or going full custom loop. The $900 price tag didn't last long either as owners of the FX8320/8350/8370 were pushing 5.0GHz OC, at half the cooling needs and on any decent 990FX chipset mobo and some 970's.

All of the 125w (that includes a couple of FX4 series cpus too) and the 2x FX9 series cpus are the exact same cpu base model. The only differences being exactly what nodes are active, which are disabled and some of the internal voltages.

The core temp for those FX is 62°C. Which means package temp @ 70°C. Beyond that and you start hitting throttle/damage ranges. The 9590 is not Intel, it can't do 100°C ish max. 70°C instead, which is @ thermal margin of 0.

Best thing you could do is put that 9590 on eBay, and replace it with an 8320/8350/8370 and get some OC, 4.6GHz or better. The H60 is good upto @ 4.5GHz, but it'll take the next size up, a mid range air like Noctua NH-D14 or 240mm AIO to maximize thermal margins under loads.

Well, I have already mounted the FX8350 instead of the power beast! ...and It runs well. I'll might try to push it a bit.

I think I keep the 9590 to play with for fun later. I live by the polar circle, so the extra power will just add some heating to the house 😛

I've done so with a bunch of old, economy model laptops with great success:
  • Cheap "new" optimal CPU and RAM from eBay
  • A new 2.5" SSD-disk as system disk
  • And a docking kit for the old disk instead of the DVD-ROM for storing...

The laptop I use when writing here, is a 11yo Lenovo economy N200. With these 100$ upgrades it works just as well as the one I got from my employer two years ago... :)
