Asus X299 Sage pro ii supports 256gb ram (same as TRX40). I am just more worried about the heat it would dissipate when not using many cores as well ? [Do you think 256gb is also not sufficient ?]? [TR pro 5955 is 280w vs i9 10980xe is 170w, and i9 is on discount for $700 vs 5955 for $1300, but sage pro ii is same as asus creator or wifi]…In case if i decide to go for Threadripper pro 5955 which motherboard would you suggest ?
Long story short, ECC is a big deal if you want stability. It’s not particularly pertinent to DL. Moreover, registered (buffered) dimms are required if you want >32Gb per module.
As for you other questions, what do you want to do with that machine you plan to build?
Are you aware of the challenges posed by a multi-gpu workstation, particularly if liquid-cooled?
If you have enough money to spend, I think you will be better served by a professionally built solution (e.g. Comino, Lambda, Puget, Byzon, …).
There are rumours of a new Titan series card, which will allegedly have 48GB VRAM. If it does get released I assume the overall system cost, whilst high, will be cheaper than 2x4090s and it will be much easier to cool/power etc. Training will be slower though… More info here:
