Help - Memory Presets?

[SYegor]

Hi,

I have a little problem that I can't figure out, so I'm here for help...


I have overclocked my memory to 3866 and it's stable.

I have (TWO) Memory Presets in Dram timing Control

1. 1.40v 4000Mhz 4x8GB Single-S B-Die

AND

2. 1.85v 4000Mhz 4x8GB Single-S B-Die


The first preload (1.40V) works, but when I load up the second preload it doesn't work. Why? What can I do to make it work? The timings are almost cut in half...


If you need to know what ram I have, it's the Corsair Dominator 8GB X 4 - 3866MHZ (CMD32GX4M4B3866C18)

The latter may be a base setting for ln2. 1.85v is a ton for ambient cooling...

What does that even mean?

ln2 = liquid nitrogen. people use it to overclock to extreme levels.

3600 CL12 may not work on most motherboards. ASUS uses the same profiles in all their higher motherboards, even in those that can't handle that. Also voltages past 1.6-1.7V are for competitive benchmarking so for short period of time. No one will guarantee stability or even that your rig will boot at these settings.

I would play with 3600 16-16-16 1.35-1.40V command rate 1N or 4000 18-18-18 1.35-1.40V command rate 2N.
