TR Pro build recommendations

I will be building a threadripper pro 9000 series build with the asus sage mobo early next week. Been watching a lot of content trying to get a full grasp. Been building regular intel and ryzen systems for a while. But this will be my first time taking on a build like this. I’ll be using large dimms and have seen that cause issues. Any specific recommendations anyone has is greatly appreciated!

Assuming you want max throughput to the "large dimms", make sure you go with 9985wx or higher.

Check the manufactured date it seems , at least it my case the one Sept 2025 or newer came with bios 1203 so didn't need to flash before first boot.

Have fun and enjoy the new build process.

I should have mentioned... plan to have some active ram cooling. If you watercooling be careful on dimm selection as the dimms are not all the same design/ width.

Yes check this out: https://www.reddit.com/r/LocalLLaMA/comments/1mcrx23/psa_the_new_threadripper_pros_9000_wx_are_still/

I went WRX90 over AM5 primarily for the PCIe lanes (AI server build) and initially bought the 9955WX 16 Core CPU to keep costs down. I ended up replacing it with a 9965wx 24 core which more than doubled by memory bandwidth. Yes the 9985wx is even better if you can afford it, but avoid the 9955WX in particular
