I am glad I decisively ordered 96GB (2x48) DDR5 ECC back in June, alongside the 9800x3d.

I hope this is still enough for the planned upgrade to Zen7 in 2028.

I'm looking at building a new system, and was waiting to see what happens with this chip and Intel's Arc Pro B70 card. I can't find ECC UDIMMs of 64GB per-stick to make 128GB, but I can put together two solo UDIMMs of 32GB or 48GB for $800 and $1000 per stick respectively.

I really want to see what enabling the L3 cache options in the BIOS do from a NUMA standpoint. I have some projects I want to work on where being able to even just simulate NUMA subdivisions would be highly useful.

I was surprised to find that ECC modules available were 24 or 48, so 128GB with 2 sticks was impossible.

While I was aiming at 128, I settled for 96GB, because any more than 2 sticks means a sharp drop in RAM clocks this generation.

You're basically me. I was mulling 48 vs 96, decided 200$ wasn't worth quibbling too much over and bought 96GB in August.

Feeling pretty chuffed now XD (though still sad because building a new PC is dumb when RAM costs more than a 24 core monster CPU)

This is the good side.

The not so good side is that getting a RVA23 development board this year with an usable size of RAM (for e.g. compiling and linking large code bases) is not going to be cheap.

Same... got 2x48 DDR5 for $304 back in February of 2025. Equivalent kits are going for $900-$1,100. Madness.
