I've already tried adjusting multiple settings manually for timing and mhz without having xmp turned on and I still get the failed to overclock screen,
But the fact it says the highest memory support from my processor is 1333mhz has me wondering, but as far as that goes I am not sure what else I can try as I have already tried punching in the timings for the rams spec.
It is not correct that that is the highest memory for your processor. That is the highest memory Intel guarantees according to a spec. Intel specs are conservative and almost always XMP over what Intel says works, and Intel supports XMP. Look in your manual. If the Intel memory spec for processors were the limit, there would be no RAM rated higher than 1600 MHz, because no Intel process specifies over 1600 MHz.
There is probably something else going on. You can go to the RAM manufacturers page and they usually list what motherboards are compatible with your specific RAM. There may be an incompatibility. You may have incorrect timings. You may have too low of RAM voltage.
What is the exact model of RAM your have (from the box)?
Their is always a possibility that ram can be bumped along with cpu until you find a sweat spot.
It will depend on the luck of the draw of your hardware and how much time one is willing to spend tinkering. On some systems XMP will drive other things way out of specs including voltages. Which does nothing but BSOD or over heating.
Over clocking has always been trial and error and it will always be.
No two cpu, motherboards, memory controllers, ram, ect. act the same way, even with the exact same hardware.
I have never had a system that couldn't handle DDR3 1600 with the voltages set to manufactures specs. The difference one sees on a system at 1600 compared to 1866 is so minor it no big deal. In fact one would be hard pressed to tell the difference unless one is using one of those bragging rights programs.
Comparing over clock settings from one system to another is pretty much a wast of time. One has to use the try and test to come up with what works for their system.
Intel XMP is pretty sound and won't drive voltages out of spec, not much of the luck of the draw there. Intel embraces it:
Intel and Overclocking DDR3/DDR4 Memory
Ah, that didn't help, sorry. I was hoping I could dig up some information on compatibility but couldn't.
I would try one thing, then contact Corsair or get on their forum. Try putting it on XMP and then up the RAM speed to 1.55 or 1.6 V.
I would try and relax the timings to see if that helps. Once it runs correctly, tighten them up until it fails again. Then you have your sweet spot, as Layback Bear puts it.
I would try setting the timings at 10-10-10-30, or 11-11-11-30 with the rated voltage to see if that helps, then slowly tighten them up toward spec to see when they fail again.
Sometimes RAM won't run at it's advertised timings on a certain motherboard. I have a set of Mushkin DDR3-1600 8GB that refuses to run at its advertised timings. Even with help from Mushkin, it's a no-go. We determined that it's an incompatibility with my board. They'll run happily at 10-10-10-28, but not 9-9-9-24 as rated. Sometimes it just won't work.
Bryan you did just the thing most of us have to do when over clocking.
You tinkered, adjusted and tested until you found what worked.
That is all I'm trying to say. It takes time unless one is very lucky to find the sweat spot.
Their is no one solution that fits all computers. Even the ones with the exact same hardware.
XMP works on some system and on some it doesn't.
Intel and Asus indicate that XMP works all the time. Well folks it doesn't.
Right here in the specs for your board it says * 1600MHz and higher frequency is supported by Intel® 3rd generation processors.
So Jack is correct in post #4
How did you overlook this ?

Microcenter sells it the cheapest.
It would also be nice to know the exact ram being used.
System specs don't make any sense.
