New CPU. Prime-95 says: ERROR ILLEGAL SUMOUT

post #1 of 7
Thread Starter 
My specs are as follows

Mobo: Asus M5A99FX Pro R2.0

CPU: AMD FX 9590 (8-Core, 4.7GHz)

RAM: 32GB

OS: Windows 7 Professional 64-bit

Power Supply 750W

Cooling: Kraken x140

All settings are stock, but the previous CPU was overclocked.



Got the error when running Prime-95 after installing new CPU. Reseated the memory and running a memtest over night.

Any other ideas/suggestions would be greatly appreciated.

Not unusual for the Vishera's to fail prime at stock speeds, it's a huge load to try to run on 8 cores. More Vcore helps in most situations, if you have the cooling.

I have a Kraken x140 Water Cooling System.

What should I change the Vcore value too, and how do I accomplish that with my mobo?

Is that motherboard rated for the 220 watt chips? Better be sure about that before you start stressing.
Use HWINFO , or HWmonitor to keep track of your system temps before adding any voltage. Can also use coretemp too . Try running those programs while you are priming and see what you get for temps.

Temps get pretty hot. Saw numbers near 60º Celsius during stress testing.

Still trying to understand why the illegal sumout error appears and why the workers stop during the test.

I guess ultimately I was hoping I could get some advice on how to configure my Bios for best performance.

well an illegal sumout just means you need more voltage,,,now the 9590 is a 220 watt chip,,your m5a99fx pro has only a 6+2 power phase design,,not really the motherboard of choice for a 9590,,,you need a board that has 8+2 power phase design,,like a crosshair v or sabertooth,,,your probably getting that sumout error because motherboard doesn't have enough power for the 9590,,,so either get a better motherboard or take the 9590 back and get a 8350 or 8320,,,,
