In this thread we will post tools for Z390 DARK OC, like software, BIOS and other bits and pieces to make get good OC results.

• OC Software

 
ELEET Basic 11/28 - Z390 - Updated 11/24
ELEET Basic 12/05 - Z390 - No WMI dependency, supports WinXP
 
ELEET Lite version, with all non-related to OC stuff removed, so it loads bare minimum to do realtime settings adjustments.
 
This is not a setup package, so you must unpack the program into folder, and run by executing ELeetX_x64.exe (or ELeetX for 32-bit OS). Make sure WinRing0 and FlashTool folders are present in same location, or program will not run.
 

 
 
Tips and tricks
 
WIP

when you get the chance, can you explain VRM voltages and how they help.   seems they range from 300-1000 and default is 500 khz.

I would echo Snipes7 question.  E-leet for the X299 Dark freezes windows when any change on the voltage tab is applied or when saving or loading a profile.  This happens when the DRAM profile needs a high voltage of 1.40v or more, including XMP profiles.  DRAM profile that needs 1.35v or less does not suffer the freezing. Does E-leet briefly drop DRAM voltage in the process of changing other voltages?

still nothing?

xp doesn't work with 1.03 bios ? 
 
we need more voltage in eleet software . like vttdram vsa vio .... please 

when will the bios for XP be ready?

second link work well on all os for me 

danteafk:  That freezing happens with version 6.0.0 when changing any voltage while the memory profile needs more than 1.40 Vdimm.  It also happens when trying to save or load a profile.  Response to this bug on the X299 Dark is the only time I've been disappointed in EVGA customer service.
 
The two E-leet versions in the OP are version 6.0.1 and 6.0.2 respectively.  I use 6.0.2 in Windows 7 and 10.  No freezing, but then no profile saving or loading either and the list of adjustable voltages is quite limited.  Try it.

Can you share your BIOS screenshot with all voltages, and then what voltage you trying to change in OS that cause freeze? 
Standard ELEET versions are kinda broken :(

my bios settings: https://imgur.com/gallery/JEyAZND
What I try to change in eleet tool: https://abload.de/img/capture4sjg7.jpg (would be cool if this tool could have the same functionality (and working) as asus turboVcore)
 
the tab does not even show the current vcore that is set by default
 
As of today the voltages tab only shows vcore and vdimm now, it used to show much more like sa/io etc - I did no changes

 
if you change only vdim eleet set 1v to your cpu so it's freez system . if you change the two voltage in eleet it works without problem 

If it had 4 dimm slots I would of went with the dark this time.

Thanks TiN :)

XOC/XP BIOS is updated in title and in guide.
Please use this BIOS for any LN2 benching, it fixed few important bugs.
