I currently am still working on redoing my water loop. The kingpin board being E-ATX does "fit" in the corsair 5000d but it just wasn't working well. I ended up buying a Lian Li o11 dynamic XL and it fits the board and loop much better. I also grabbed the o11 distribution plate too to make life easier. Still waiting to find time in life to install hardline tubes.

I also finally got a new in box replacement board. They ended up sending me a maximus extreme board. It's nice they did that but now I am having a hard time selling this board. Seems no one wants an 1100 board...trying to sell for $900 but no bites locally yet. No idea what I am going to do there

I am not sure but it seems people have lost faith in ASUS mobo's on the high end this generation. I am confident my kingpin board will work well once I have time to finish the setup, it looks great so far

Daily work horse still powering along since last year no problem after stability was dialled in at the time. Not even really felt the need to try Hynix, yet.

To those encountering stability issues with 1505, its because the Memory controller VDD doesn't like to be too far below stick vdds.

I just wanted to post an update. Couple of pages ago I wrote that I can not boot on xmp profile with my Gskill 6000 rams which is in the QVL list. Thanks to Asus Turkey they could not find a working motherboard for me. I have tried 4 different Apex mobo thanks to retailer not Asus Turkey.

Finally, I decided to buy a MSI Unify-x, boom no issue with xmp anymore even I can boot 6800mhz @1.38v. It is not yet stable needs some fine tuning. But there are my results at 6000mhz and 6400mhz.

Same CPU, RAM ....

This issue crystal clear to me.

Hi,

I have an APEX board 90MB18IO-M0AAY0. I have this because I had the Hero board with the reversed capacitor and sent it back. I really don't feel like ripping my board out again. Is there a "known good" DDR5 2x16 or 2x32 which will work on this version? I have a 2x16 Gskill 5600 set now but I can't run XMP only default timings.

Thanks!
