Hello everyone,

I've been trial and error building my system for the past three weeks now. The short version is I bought some used (supposedly working) parts from a buddy but ran into some compatibility issues with the video card and my OLD motherboard (which was an Intel DP67BG). Basically, I was able to the boot the system but the display adapter would crash IMMEDIATELY when any 3d application was ran.

I figured it was the motherboard so Intel was nice enough to send me a new motherboard which is what is listed below (DZ77).

My concerns now is with this new motherboard, will all the parts work together? And if they will work, do I need to adjust the timings of the RAM or set the voltage to something different. I've been reading the voltage should be at 1.5v and timings manually adjusted. I'm very confused and am just tired of all this TS'ing. :( 

Thank you so much for all your help!

Here is what I have now:

Motherboard:
Intel DZ77RE-75K

Processor:
Intel i7 2600K

Memory:
PXD38G1600LLK
DDR3 1600 (PC3 12800)
Timing 8-9-8-24
Cas Latency 8
Voltage 1.65V

Video Card:
XFX Black Edition R9 280x

PSU:
CX750

Thank you again.

The voltage for newer DDR3 memory is 1.5 but much of the older stuff or the high end DDR3 memory of today runs at 1.65v. It really will not hurt anything by doing so. If you go into the BIOS you may be able to find the memory XMP profile which will automatically set all of the settings at 1600; however, all boards are different so this may not work for you. Even if you cannot get it to run at 1600 it should default to 1333.

Simply go into the BIOS, enable XMP and select profile 1, it should set the sticks up for you, any problems give a shout

I've read that 1.65v will shorten the life of my 2600k and even the mobo manual says to use 1.5v. This is where I'm most confused. I read though that since my mobo uses 1.5v that it'll down clock it to 1333. If that is the case, is there any custom clock settings I should use to get the most out of 1333?

I've had 32GB of 1.65 DRAM in my P67 for a few years now and fully expect it to continue running for years to come.... ;)

Thank you for the responses thus far.

So the recommendation as it stands as of now is just to use the XMP setting or manually configure it to the manufacturer's printed 1600 setting?

The XMP profile will enable the memory to run at the printed timings and settings on the memory stick. It just does it for your automagically.

Thank you.

So if I want to keep it at 1.5v (I'm had so many issues and I'm afraid of more) are there any recommended settings?

The XMP profile will probably set it to 1.65v if it is there; however, 1.65v should really not do anything to cause system instability. You can always go into the settings and change the main three timings to what is listed on the memory, frequency to 1600, and then change the volts manually to 1.5 and see if it will boot.

If any doubt simply try 1600 9-9-9-24 1.5
