Hi all!
Just posting for posterity here. I recently picked up a little Seneca xView machine for around $100 US. The machine is for digital media, running TV’s etc. I thought it would be interesting to see what one of these little cheap machines could do. The machine comes with a Zen1 era embedded 4 core CPU, with Vega graphics.
According to AMD’s official spec, the AMD Embedded Ryzen 1756B only supports 32GB DDR4,
AMD Ryzen Embedded V1000 Product Brief
On some older Intel systems, especially on DDR4, the product spec says 32GB max, but, they accept 32GB DIMMs. This has to do with the fact that when the machine was built, 16GB DIMM’s where only available, and the CPU vendor does not go back to re-validate the larger 32GB DDR4 memory modules.
On that hunch, I installed 2, 2666 DDR4 32GB SODIMMs, and the machine booted! It shows memory running at 2400 in the BIOS. Here is select outputs running Ubuntu 22.04 HWE 6.8 kernel,
[ 0.452202] smpboot: CPU0: AMD Ryzen Embedded V1756B with Radeon Vega Gfx (family: 0x17, model: 0x11, stepping: 0x0)
[ 0.294614] Memory: 64555992K/66014200K available (22528K kernel code, 4438K rwdata, 13892K rodata, 4972K init, 4740K bss, 1457948K reserved, 0K cma-reserved)
So far, running Docker containers 24/7 for the last couple of weeks without any issue.
Thought this might be interesting for someone in the future looking at what this little old CPU can handle.
