Memory Upgrade causes boot loop

Ahoy,

I've had a look at the other treads on this topic and can see they are relatively customised to the specific build. That said, I've tried all the common actions (listed below) and thought I'd create a new one.

So, the current build:
MOBO: Gigabyte GA-Z68XP-UD4 ATX LGA1155 Motherboard
CPU: Intel Core i5-2500K 3.3GHz Quad-Core Processor
RAM: Kingston HyperX Blue DDR3 1600 1.5V 2Gb x 4
Then some other stuff....(ask if you think its relevant to the question).

I'm wanting to swap out the 4 2GB sticks with some new RAM I've purchased:
Kingston HyperX Fury Red DDR3 1833 1.5V 8Gb x 2 (HX318C10FRK2/16)

I've been removing all the previous sticks and putting the new ones in slots 1 and 3. This caused a boot loop, so I tried again with just one stick in 1. Again - boot loop.

Since then I've tried a number of things (Clearing the CMOS and manually updating the BIOS with the old memory in to reflect the new speed, then restarting with the new stick in).

So far as I can tell, the RAM is supported (Gigabyte doesn't have a comprehensive list but it adheres to the general RAM guidelines and is also not flagged as incompatible in pcpartpicker.com).

Anyone have any ideas on what I should do next? I'm not sure how to go about a memtest if the comp won't boot up with the new RAM in it, and when I revert back to the old RAM all 4 slots seem to be picking up and functioning ok.

Thanks
Dave

Just heard back from Kingston - this RAM requires a UEFI BIOS.

I was still on the old F5 version of the Gigabyte BIOS, so upgraded, switched the RAM and voila!

Anyone else with this problem, you can check your BIOS version from Windows via this command in cmd:
Code:
wmic bios get smbiosbiosversion

Gigabytes update utilities didn't work so I went for the solution detailed here:

And the BIOS version here:
http://www.gigabyte.com.au/products/product-page.aspx?pid=3977&dl=1&RWD=0#bios

Obviously it'll be different depending on your specific setup but these steps worked well for me.

Thanks

All you need to do is reset CMOS then the new memory will work.
Install the new memory, unplug the power supply from the wall, remove the battery from the motherboard/ or use the jumper if your board has one. wait about 3 minutes if you removed the battery then stick it back in. then you should be fine.
Your PC still thinks it has the old memory installed till you reset CMOS.

This isn't correct.

While I understand this is a common solution to this problem, as I said in my post I had already cleared the CMOS (in fact I had tried this a number of times in both battery and jumper ways as per the motherboards manual. I'd also tried manually setting the BIOS settings to the new RAM specs prior to installation. These methods did not work for me.

Kingston has stated this memory is not compatible with non UEFI BIOS's. flashing the BIOS with their latest UEFI version fixed this.
