DDR5 & 4 Dimms?

[Snipe]

So back when I bought me current system I ended up buying 2 kits of DDR5 6000 ram, I built the system and setup XMP all was good.  The system installed Windows and everything ran good, then I got random BSOD's and that is when I found out that JayZ2Cents did a video on unstable DDR5 @ high speeds.  I was able to force some errors to confirm and that is when I was like I will just lower the speed a bit, ya it sucks but it will work.  I left it that way for a year and a half until this latest Intel BS and I updated the BIOS and the the Micro code update.  I had read on a few previous bios updates (that I never did) that is provided better memory compatibilty, I always wondered what that exactly meant.  I just realized that after that update it defaulted my ram to 4000mt so I decided to enable XMP again at 6000mt and it seems stable. I even did a Windows Memory Test which it passed.  Has anyone else been able to confirm that with the newer BIOS updates they are able to run memory at speeds they couldn't before?

 

EDIT:  I did run Prime95 Memory stress test and it seems to be working fine, if I recall I did that before and I was getting errors.  I always thought that if you had a CPU with a not so great memory controller, there wasnt much that could be done?

It is normal for the ram speed (and other settings) to be reset after a bios update.

 

Bios updates can improve compatibility. I have experienced this on other platforms in the past. This is especially the case on early bios after a chipset is released.

 

4 dimms as a specific case is more challenging to work at higher speeds.

I'm running 4x16 at expo 6000 36-36-36-96 which is my rand rates speeds, on a 7800x3d with July bios.

 

It's hit or miss but as the memory controllers and bios mature we'll see more of it.

Yes I get that the ram speed would reset, I thought it would but I forgot to check it after the update. The biggest thing I was surprised with is the speed I can run now after the bios update.  Intel had issues with maintaining 4 dimms at high speed.
