Hello.
I was using a Pentium G3220 as a backup since my I5 4440 died after 1 month of using. Today I bought this new I5 5675C to use with my GIGABYTE Z97M-D3H.
First I updated the bios to the latest version (F8), which support Intel 5gen processors as stated on Gigabyte's web site. I booted using the IGP (Iris 6200) and weird things started to happen. As I'm a Linux user, sometimes I was able to see the Login screen, just before it became all full of artifacts and the computer froze. Sometimes I was able to login and use the computer for no more than two minutes before it happened. Less frequently, the machine would just restart when the login screen was about to show up. This is what happens when the artifacts show up an the system freezes:

I have cleared the BIOS, took everything off and assembled it all again, tried booting with a new Ubuntu Live CD and no luck. I reverted back to the Pentium G3220 and I'm able to use it's IGP, so I discarded any problems with the motherboard's DVI/HDMI output. Everything single part of my system works with the G3220, I only have problems when trying to use my new 5675C.

My current system is as follows:
Gigabyte Z97M-D3H
32gb (4x8gb) DDR3 Kingston HyperX Beast

Am I realy this out of luck to have two defective CPUs in a row?
Thank you in advance!

UPDATE:
By the way, I noticed that the problem doesn`t happen when I`m using only 16gb RAM (only two of my four 8gb modules). I read somewhere that this Broadwell CPUs are made to be used with DDR3 1.35v RAM, while all my modules
are 1600mhz 1.5v. However, the review here on tomshardware states that they were able to run with DDR3 1.5v modules.
I`m really confused, the system runs rock solid with only two 1.5v modules, but when I`m using four of them the troubles appear.
 
Solution
Yes, two 2x8gb sets, same model, worked well with the G3220 for months!
Tweaking around in bios I was able to set the XMP to Profile 1 and by reducing DRAM voltage (now at 1.2v) and raising the timings (now running at enormous 14-14-14-34!!) stability improved, I am even posting using the 4 modules in a new ubuntu installation right now.
My RAM is composed by two sets of Kingston's KHX16C9T3K2/16x.

Solution
Well, after a while the same thing happened even with the voltage and timing modifications. I'm using an external GPU and everything has been working perfectly for hours, so I believe I have a defective CPU, as I only have problems when using the IGP.
I will try to exchange it for another unit and see what happens
