So I recently "upgraded" to the lga 1366 platform. I picked up an asus P6T motherboard and an i7 975 for 100 bucks! Now of course right when I installed it I did a relatively tame overclock to 4.03Ghz/134FSB/1.2875Vcore. It passed prime95 after 24 hours fine. A couple weeks down the line it began having issues after I moved from windows 8.1 to windows 10 (problems I think are unrelated to the OS upgrade). The problem is that the CPU will not overclock anymore if I even touch the multiplier it will boot into windows and promptly blue screen with the errors Whea_Uncorrectable_error, Some other one like fatal hardware error, and if it fails to boot it will give Inaccessible_boot_device for some reason. I'm not certain if this is a problem that comes down to the mobo, cpu, or ram. Could even be some crazy software bug, but I doubt it, it is only the latest bios, no temp problems at all. I would love a second opinion.
P6T + 975 for $100 thats insane... very jealous.
How is the stability with no overclock at all? If stable then re-do the oc.
Also - just to rule out windows boot off a usb stick with a linux distro.
Things I learnt from X58 overclocking
- keep the northbridge and in fact the whole board cool with good airflow
- keep the VTT the same (or close to) the VCORE
- IOH & ICH < 1.3v
- ram ram ram.... triple channel setups seem to become flaky after a few years with heavy abuse of the motherboard - so test with just a single stick, or 2.
- play with the base clocks and multi's & QPI..... I really miss this. Shame modern intel overclocking isnt half as much fun. Should be some good guides around on the web.
Best of luck.
Flash to the latest bios, if you already got the latest bios reflash it.
Try with another stick of memory, try with only 1.
Might be some SATA problem with the south bridge, tried other sata modes? ACHI etc.
Hi ! check your psu for stability; the voltages stability are imperative to OC. From personnal experience the X58and P6T are one of the most easy to OC.
The voltages must be off, DO NOT INCREASE VCORE IF YOU DO NOT KNOW THE DRILL.
And yes, I WOULD suspect the upgrade.(the OS communicates with the bios)
Reset to default all on MOBO. (if you want save the setup you have presently in bios. (if possible), and go from there.
Thanks for all the responses! I ran memtest86 to rule out the ram it passed with flying colors, with xmp enabled. Now I tried to boot at my regular OC of 4ghz, it bluescreens during boot now gives me Machine_Check_exception. any amount of adjustment to vcore causes a blue screen. However if I only adjust the multi it will boot into windows and then fail prime95.
-I also re flashed the bios to 1408
-tried to boot from a linux distro/hirens when overclocked, no dice froze on boot
-AHCI mode doesn't work I presume because I installed windows in IDE mode
-The stock CPU is 100% stable on prime95, leading me to believe that its the mobo
-PSU could be in question although it should be able to boot an relatively idle i7
luckily if it is the mobo I can get another for 30$ the cpu however...I won't find a deal like that again lol,
let me know what you guys think and thanks for the help.
