New RAM stops system booting

So i recently bought a 2 x 8 gig kit of 16GB 1600 Kingston Hyper-X RAM to replace my old 2 x 2 gig G-Skill 1333 kit.

I put the new RAM into the system and tried to boot it up but it just turns on for about 2 seconds then powers off again. It then turns itself back on and repeats.

The gigabyte site says the specs for my MB can support

"4 x 1.5V DDR3 DIMM sockets supporting up to 16 GB of system memory"

The new RAM kit is low voltage 1.35V RAM... could this be the problem?

Put the old RAM back in and works fine.

Motherboard: ga-ep45t-ds3r

CPU: q9400

GPU: Radeon 7950 OC

PSU: Coolermaster 700W

    sounds like you got some bad RAM, same thing happened to me when I changed my RAM a couple months ago, just return it and exchange for new pair.

    Try this. With the old ram in the board go into the bios. Change the voltage to 1.35 and the timing on the new ram save and shutdown. Swap out ram. See if it works.
  3. Tried changing the voltage to 1.35 in BIOS. No luck, thanks for the suggestion though.

    I think that rgd1101 has the answer to my issues. Since the board only supports a total of 16gb and has four slots I doubt that it supports 8gb on one slot. So i might need to change kits.

    Well I am at work and can't seem to get to Gigabyte's site but I would agree that it may only support 4Gb per slot.
