Hi All,

Hoping for some advice to look in the right direction. I recently finished my build, Rampage Black IV and am having seemingly random reboots of the machine with no warning. Specs:

RIVBE (updated to 0507)
i7 4930k
32gb GSkill 1866 ram
2x EVGA 780ti
Corsair AX1200i PSU
Windows 8.1

I thought initially it was a PSU issue, and replaced an HX850 with the 1200, but the problem still exists. The system will just reboot instantly, no warning, and there is nothing is the event log until it reboots. It doesn't seem to be anything in particular causing the issue, though it tends to happen more when I'm playing a game (even games that aren't remotely using any significant amount of resources). I have also monitored temps on the video card, and processor, and they are completely fine any time this issue has happened.

I'm really just looking for some advice of where to look next, I can't seem to pinpoint the issue at all.

Thanks.

Welcome to the forum!

First of all is anything overclocked? If so, return them to stock settings.

My first instinct would be the PSU, but the AX1200 is a solid unit.
Can't rule it out though, do you have a voltmeter to measure the +12v rail?
Next, I would focus on the memory, have you run memtest on each stick individually?
Then test each 780TI individually and if needed, in different PCI-E slots.

Try restarting BIOS to default, clear CMOS. Try with all stock settings.

Use memtest to test all your memory. If you have a good machine, you can use that machine's BIOS to measure the voltage of the PSU if you don't have a voltmeter.

I had to RMA one of these boards a few days ago, I wish you the best.

I had the same issue set your memory up manually, Also set CPU current capability to 170%, set a mild cpu clock ratio at first to 42, Digi+ LLC to medium. Be sure before hand hit F5 in your bios. That should help..
