I have an FX8350 and an asrock 990FX. My cpu cooler is a coolermaster hyper 212 evo and have another 4 fans (3x120mm and 1x240mm). I notched the cpu to 4.2 GHz thinking it would be good but prime95 failed almost inmediately saying something about illegal summout. I put the cpu core voltage up to1.41 V. prime95 failed again but this time it took 3 minutes and it didn't say anything about illegal summout. I'm not sure what the problem is 🙁 Do i have to put the voltage a little bit higher? I tested again and after 2 minutes a core stopped working and the cpu temp on SpeedFan went up to over 50 degrees Celsius. In 2 minutes! It went up very quickly. I am testing again right now with the voltage another 0.125 more but it still heats very quickly. Now, the problem isnt the prime95 test, but simply the temperature. I felt like my computer would be very good against heat but i am being proved wrong. Could it be that SpeedFan is wrong? the temperature on HWMonitor says that CPU is at 38 degrees. SpeedFan is already at 53.... Im not sure which one is the socket and which the core but there must be a problem 🙁 it failed again saying "illegal sumout" exceeded warning limit (100) and that i should read the readme.txt file.
"Could it be a software problem? If the error is ILLEGAL SUMOUT and you are
running Windows 95/98/Me, then there is some chance that this is a software
problem. A device driver or VxD may not be saving and restoring FPU state
correctly. Windows NT/2000/XP/Vista protects prime95 from bad device drivers.
In that case ILLEGAL SUMOUT is very likely a true hardware error. The good news
is that prime95 recovers very well from ILLEGAL SUMOUT errors. Try seeing
if the problem occurs only when a specific device is active or a specific
program is running." That is what the readme.txt file says. I don't get what I should do. Please help!
