Hello, i am a new to the forum, I want to buy the evga dark kingpin z690 but I want to know if it is also compatible with 48gb RAM modules for a maximum of 96gb.
I hope you can help me.
Thank you.
48GB modules have not been tested on our end to my knowledge. Our MB team thinks they should work with the latest BIOS, but we can't guarantee compatibility at this time.

EVGA z690 Dark Kingpin
CPU i9 12900K
Will it use 24 gig kit?
Thinking about getting the Trident 2x24 8000 kit, although I am considering waiting until there is more information from forum members on this, cause I would like to know about 48 gig modules as well.
I have the F5-8000J4048F24GX2-TZ5RK 2x24g kit and it works... kinda... It does not work at the rated XMP speeds, however, I can get it to run up to 7400mhz @ 1.35v. It will boot at 8000 just fine with XMP... but something like TestMem5 Extreme1 @anta777 will start throwing errors within a minute or so. This means that it's not hard-crashing... but I tried for several hours to bring some stability at that speed and wasn't able to. So for now I'm stuck at 7400mhz but am starting to strap down the timings to see where I can get with these 24g-m-dies.
I just don't think the Z690 board is capable of running at that speed to be completely honest. Unless there is something that can be done through a BIOS update, then I'm guessing that this is what the difference in layer count for the Z790 Dark is related to. There are seemingly very few difference between the two boards but the layer count likely contributes to better stability at higher frequency memory on the Z790 Dark. Would've been nice to know these limitations before buying but it's a good board none the less. I suppose this could also be down to the IMC in the CPU but I have tried a 12900k a 13900k and a 13900ks all with no dice so again, my guess is a motherboard limitation 
. Maybe someone from EVGA can help clear this up.
Wondering the same thing... is z790 really that much better? If so why? The Apex is 10 layers.... and the Dark is 10 layers, yet the z790 apex wins in overclocks
Z690 and Z790 are basically the same. Intel even said not to expect a performance improvement with Z790. The dropped Optane support (hardly anyone cared about it) and freed up a couple of PCIe lanes for something else.
People don't realize that CPU and memory, and motherboards, are all subject to the silicon lottery. My Z690 Dark runs 8200 stable with tight timings with an average 13900K and a better than average 13900KS, but ONLY with lottery-winning memory modules. Just because you are sold an expensive memory kit doesn't mean it is a good one. Just because you paid out the nose for an expensive motherboard doesn't mean it is a good one.
Cases in point:
- I have RMA'd more than a half dozen expensive retail memory kits that were garbage
- My Z690 Apex is an absolute piece of trash... can't do more than 6800 stable with any memory modules... period
The screenshots below are my Z690 Dark using generic green OEM naked (no heat sink) A-die modules, with no XMP profiles, that I purchased for $100 each and they perform better than the retail TeamGroup and G.SKILL A-die modules. My memory is water cooled and maxes out around 35°C under stress.
If your memory is getting into the 40-45°C temperature range running TM5 or other memory testing utilities you are likely to see errors once the temperatures get to that point. And, you'll need some memory voltage (anywhere from 1.475 to 1.600V) to run good A-die at 8000 or higher. Also, don't expect the XMP profile to be stable. You will often need more voltage and may also need to tweak some of the timings manually.
