Hi
I wonder if i could get some advice. I have the following new components:
Gigabyte Z390 UD
i5 9600K - Also tried 9600KF (see below)
2x8GB Cruicial Balliastix 3200 (stock 2400 for testing)
Corsair CX650 PSU
WD Blue nvme 1TB
Arctic Freezer 34 CO
Win 10 Pro x64
Also using a used GTX 1080 and 2 used Crucial MX500 SSDs (all working fine with my old machine)
Only about a week old, no issues in games etc so far, no overclock has been applied at any point.
Wanted to see if i could overclock so tested stability/temps at stock first, Prime 95 fails small FFT test on one core almost instantly. Has also caused instant lock ups and a blue screen. Blend test fails when it gets to the small FFT part. LinX fails within 10 minutes. Temps are ok and the highest core temp i've seen is 71c.
I assumed the CPU was bad as it was always the same core that failed on prime so I ordered another (a 9600KF this time due to price). Dropped it in, cleared the CMOS, and the same issue happens. Seems to be a different core failing now on Prime 95 but I have seen failures on different cores. My LinX test on the new CPU failed in on the first run - within 10 seconds.
When Prime fails the other cores seem to continue ok but I havent left it going for more than about 20 minutes after the first failure.
Latest BIOS used for board (F9). CMOS reset multiple times. I have tested the RAM using windows memory test and memtest64 for about 30mins without issues. Clean Win 10 install.
My next instinct is to try another motherboard, I dont have another so will be getting one delivered. Worth going for a better board? With better VRM?
Seems unlikely to be the PSU as no issues occur running the GTX 1080 under full load while gaming. Can't think what else could be wrong!
Any input would be appreciated.
Many thanks
Alexis
