Hi all
Really hoping someone can help, as I'm pretty much stuck for ideas on this now.
I bought my VIII Hero as part of an OC kit (with a guaranteed overclock of 4.5GHz) I ran the system at stock for a couple of months before applying the settings and ever since have run into issues. This also occured with the default XMP profile applied.
Kit and settings >
https://forums.overclockers.co.uk/showthread.php?t=18692676The settings apply to the 3000MHz RAM that was originally included with the kit, but they since updated the kit to include 3200Mhz (which is what I received). I was advised on OCUK to clock it back down to 3000Mhz and apply the following..
"Set VCCIO to 1.2v, VCCSA to 1.25 and CPU standby to 1v. Reboot and test"
Have done this (No VCCSA in the BIOS but set CPU System Agent Voltage to 1.25 - text then goes purple if that means anything?), but sadly issues still remain.
The system works fine for a while, but after a day or two I will get one of 3 problems or a combination...1. System makes a quick audible stutter (if listening to music or playing a game) then cuts power then reboots.
2. On a cold boot (or after a crash), the boot may halt at the Safe Mode message on the BIOS, at this point my RAM clocks itself back down to 2133MHz even though all settings are still applied in the BIOS.
Only way I can boost it back up is to set defaults, (or clear cmos) save, reapply, save and reboot.
3. Occasionally after shutdown the PC will boot itself back up a minute or two later.
Other things I have tried...1. 2x OS Drive reformat and reinstall.
2. Removing the RAM Sticks, blowing on contacts, reseating.
3. Clear CMOS flashed the BIOS twice (to 1902, now 2001)
4. Even bought a new Belkin Power Strip as I was paranoid it could also be surge related.
Only other thing I changed.
Just before the OC I added the Q-Connector for the Front Panel switches, mainly for ease of use (once I realized what it was for), previously had them wired directly to the board. Could this somehow be causing a short - or clutching at straws here?
Any help or ideas greatly appreciated!
