TRX40 1TB RAM unit
Hey Guys, Does anybody know of anybody anywhere who has installed 1TB ECC RAM in to a TRX40 mobo? I'm building a new work PC which I really need to have as-hot-as-possible single-threadded performance while having 1TB of RAM (so I'd rather not have to go EPYC). I figured the TRX40 would be a good platform for that, but most mobo manafaturers state they only support 256GB - I assume, as with most things, there is a bit of wiggle room with this. Any help or pointer in the right direction would be appreciated. Thanks Dan
It's clear that certain configurations, like the 3990x, are limited to around 256GB of RAM. This likely stems from AMD's strategy to avoid negatively impacting sales of EPYC systems, which could be the same reasoning for other Threadripper components as well.
To reach 1TB of RAM you’d need to pick either Epyc or Xeon. If cores aren’t important, you could opt for faster 8-core processors instead of the usual 32-core setup. The Epyc 7262, for instance, can handle up to 4TB in octa-channel mode while maintaining solid speeds of 3.4GHz across all eight cores. Of course, this pales in comparison to the single-thread performance of high-end CPUs like the 3900X or 9900K, but it gives you the full capacity you’d need.
