A VERY Stubborn 4770K - Page 3

post #21 of 32
The memory controller is on the CPU so a memory overclock is dependent on CPU IO voltage as well as DRAM voltage. It would be a good idea to overclock your CPU first and worry about RAM later.

Otherwise every RAM runs with 1333Mhz, if not changed in BIOS

Thanks!

I am familiar with XMP. I originally set out with RAM running at JEDEC which seemed to be ok. I wasn't until flipped back to the XMP profile that I was unstable again.

EDIT:

Seems like those adjustments to SA and Analog/Digital have paid off. Stable so far where before I would have been already greeted with a BSOD.

Right now I am sitting at 4.2 @ 1.232v

The XMP part was for cyro who asked smile.gif

Hahaha i meant what was XMP changing on his mobo

Some xpm's hit memory clocks, timings, volts - others change SA from what i hear

Was suprised by the question coming from you so should have thought about it ^^

Are you missing something, a setting perhaps?
4.2 is very low to not be possible for any CPU... heck even my i7-750 could do that easily.

Haswell is much different. Don't compare it too a 750.

I recommend increasing both the analog and digital I/o 0.050v first. Haswell is a different animal when it comes to overclocking, you have to find the right voltages, as too much on one can make it unstable.

For example typically you want the VCCSA System Agent voltage to b equal too or just below your analog and digital io voltages. Don't just go throwing voltage on the chip, that's how you kill these.

What was your stock cache voltage?

lol...well..yeah!

I saved our little project here to an OC Profile then loaded setup defaults. That's what we being reported in UEFI.

The inevitable question: is that bad?

The almost as inevitable bonus question: why?

Do load optimized defaults. I have not seen a 4770k yet with that high of stock cache voltage, mine was 1.04v
