Ryzen 4750U ECC Support?

[n0ghtping]

I know this question has been asked about previous generations of AMD Ryzen Pro Elitebooks, but I haven't seen it asked for the 8x5 G7 series yet, so here goes:

It appears that some AMD Ryzen Pro CPUs can support ECC when it is enabled by the BIOS. There's much clarity on the topic, especially for the APU's like the Ryzen 7 Pro 4750U (and similar) CPUs in the Elitebook 8x5 G7 series, but it sure looks like it is possible. The current BIOS for the 845 G7 does not support ECC, but could it be added in the future? Or could this be a possibility for the upcoming G8? As one of the very few Ryzen Pro systems with dual memory slots, the 8x5's are some of the only existing hardware with any chance of ECC memory support.

What would it take for HP to investigate enabling this in BIOS? Is there a route to discuss the engineering costs needed?

Thanks.

Glad you are asking the question.

I too would like a laptop with ECC. We now have memory that is so much more dense than in previous years, (decades even), that un-detected bit errors are quite likely over the life of a modern computer.

It would be wise of HP to have at least 1 laptop, (in several sizes), available with ECC.

I've done a little more reading, and it sounds like it might take a little more than just BIOS support - there are 8 lines that would need to be run from each SO-DIMM slot to the package. No idea if HP is doing that already just to future-proof their mainboard designs. No way to know unless someone at HP support looks into it, which I'm getting less hopeful about.

Either way, I still would like to see ECC support on future Elitebook generations. I can always hope someone at HP is listening. I'm also curious what the solutions will look like when we switch over to DDR5, since those modules will be running a form of internal ECC anyways.
