Installing 4 Sticks of RAM causes repeated power cycling

[Fallfeathers]

Hello Tom's Hardware! And Tom, whoever that is.

For the past two years that I've had my PC, I've been running on two sticks of 4GB DDR3 RAM. Yesterday I bought another two sticks of identical RAM and installed them into the two free dual-channel slots. The result was that, after being powered on for about five seconds, my PC would immediately power down. Another four seconds later, it would power up again, and repeat until I turn it off at the PSU switch.

This is my current PC build:
Motherboard: Gigabyte H77M-D3H
CPU: Intel i7-2600
PSU: Corsair 850W
RAM: G-Skill 8G (2x4GB) DDR3 1333MHz PC3-10666 CL9

Again, the new RAM I bought is identical to the RAM currently installed in the PC.

Things I've tried so far:
1. Cleaned out the DIMM slots with compressed air and a gentle horsehair brush.
2. Switched the old RAM out for the new RAM. (Issue doesn't occur)
3. Used a combination of one stick of old RAM and one stick of new RAM. (Issue doesn't occur)
4. Switched the RAM to the other two slots. (Issue doesn't occur)
5. Gotten the new RAM replaced.

So really, the issue only occurs when I use all four slots, no matter which combination of RAM I use. What could be causing this?

try to update the BIOS first

run memtest on 2 RAMs at a time

You may need to increase the voltage and/or relax the timings. Some memory controllers don't take a full bus well.

Agreed one of my MBs states to get best performance use two stix, so 2 8GB instead of 4 4GB stix for 16GB total.
Since you have 4 stix do as Grandmaster suggest above

I've updated the BIOS, still no dice. Memtest reveals no errors.

Any suggestions as to what settings I should try? Currently everything is on automatic.

First try the DRAM voltage up + 0.05, if no joy with that, try raising the MC (memory controller) about + 0.06 think it's CPUVTT or DDRVTT on your mobo

Update
The issue seems to have... fixed itself? I toggled the "advanced mode" options in the BIOS for memory settings, and without changing anything, I can now boot up with all four sticks of RAM.
I wish I had a more definitive solution, but there you go. Thanks to everyone who helped.

No worries 😉 Glad all is well

Although your system will show additional memory still...
When adding memory you need to enter setup then save settings and exit.
You toggled auto so when you exited you were asked to save settings my guess is you clicked yes.
