Hi all!
Here is my system:
-Windows 7 Ultimate x64
-i5 2500k w/ Hyper 212+
-Biostar TZ86A+
-XFX Radeon HD 6850
-G.Skill Ripjaws 2 x 4 GB DDR3 1600
-Kingston 96 GB SSD
-Cooler Master SilentPro 600W 80Plus Bronze
(THERE IS SPARKNOTES VERSION BELOW IF YOU DONT WANT TO READ ALL THE DETAILS)
Okeedokee, I've had my system for ~2 months. I had previously OC'ed my system to 4 GHz (a very mild overclock for the 2500k, as you all know), but today I decided to push my CPU a bit further so I got HWmonitor and Prime95 and began stress testing my CPU.
Running at 4.0 GHz and 2.9 Vcore, one of my cores stopped working due to a rounding error after about two minutes of Prime95. I thought that was odd, because I had done plenty of reading and found that a 2500k should have no problem at this speed with this vcore. So I went into my BIOS and set everything back to default settings. I rebooted and ran Prime95 again. Same things happened. One core stopped working while the rest continued.
(Note: I have been keeping an eye on temps, and the cpu has never been over 52C in its life!)
I had read that this sort of Prime95 error can also be caused by faulty RAM. So, I slipped in the Memtest86+ disc and started testing. After not more than five seconds of testing, memtest haulted and gave me this: "Unexpected Interrupt - Haulting CPU0." At this point, it had not actually found any RAM errors, it had just stopped testing and given me this message. So, I restarted the computer with the PSU switch and tried running memtest just using a single stick: after two seconds of running, memtest crashed and my computer restarted. I tried the other stick of ram and I tried both sticks in other DIMM's -- same thing: memtest crashed and the computer restarted.
I have reinstalled my OS and nothing has changed.
Note: While normally using Windows and playing games I have not noticed any strange behavior during almost two months of use.
SUMMARY/SPARKNOTES version:
-One core consistently has a rounding error in Prime95, even at stock BIOS settings.
-Memtest throws "Unexpected Interrupt - Haulting CPU0" error with two sticks of RAM in
-Memtest crashes and computer restarts with one stick in, regardless of which stick and which DIMM is used.
-OS re-installation has had no effect on the issue.
My questions:
-Is this consistent with a particular component being faulty? I'm leaning towards the mobo or CPU, but would like to be more certain.
-Are there any other diagnostic programs I can run to gather more information?
-Help?
