i Have the ryzen 9950X3D and motherboard Asus rog strix B850-E and i have two sticks of Crosair DDR5 64GB (2X32) at 6000MHZ, will this build handle an other two stic of same ram without losing performace?

No. The chances of running 32x4 at (or near to) 6000 are very slim. Best chance is a kit of 2, 48x2 or 64x2.

Thanks you!

yeah, totally agree — if you’re not needing more capacity than two sticks could provide, two’s always run faster

I have used 4 sticks of cl30 6000 with a 7800x3d on a asrock b650e taichi without issue. maybe i got lucky or maybe the old saying off don't use 4 sticks is out of date.

You got lucky or your timings/speed are not 6000 CL30 with 4 sticks.

Many RAM experts can’t run 4 sticks at any decent speed with retail hardware.

Timings were 6000 cl30 even with 4 sticks i was running expo.

I found Running 4 sticks of SR 6000cl30 is pretty straight forward but DR is a different story.

There are two kinds of opinions widely shared on the internet: people who claim it will hardly ever work, and people saying they did it and it worked fine. I think that since people are considerably more likely to share when they have issues than when they don't this has led to a false impression of how unlikely it is to work.

Clearly some people have issues, so I wouldn't recommend it for a new build - and AMD themselves only claim support up to 3600 with 4 sticks on the 9950x3d - but with an existing build you may as well try rather than paying the extra for all new memory. You can always return the sticks and put in a pair instead if it doesn't work.

It is very very difficult to run 4x 32Gb of DDR5 on either Intel or AMD Platform at XMP/DOCP speeds anything more than auto speeds in the BIOS can cause issues. I have had the exact same part number but different version, one machine was fine others have problems. Its really really hit and miss. Most motherboard manufactures do not list 32gb modules running at anything more than auto settings when using 4x modules.

I have, however, seemed to have had much better luck with 192Gb (4x48gb) 5200Mhz/5600Mhz specifically on Asus motherboards, however the requirements for that is few and far between.
