Storage server update
In my last post I mentioned I was looking at updating the storage servers. I gave up looking for a Xeon E-2300 and instead have ordered an ASUS X570-Pro motherboard, Ryzen 5600X CPU and a Noctua cooler. I'll move PCIe cards from the old machine and I have memory. The Xeon E-2300 series and the Ryzen both have a 128GB memory limit, the difference is I can get the Ryzen and its cheaper.
I went with the Pro motherboard as it gives an extra M.2 slot and an extra PCIe x16 slot over the X570-P motherboard. I need to add a graphics card to the machine which only leaves 2 PCIe slots left for the SAS controller and 10GbE network card.
I tested 32GB ECC memory sticks in an X570-P machine (with a Ryzen 3600) and it wouldn't post. I changed to 16GB sticks and they worked. There is an option buried in the BIOS to enable ECC mode.
Given the Ryzen 3600 didn't recognise the 32GB memory sticks I decided to get a Ryzen 5600X in the hope it will. Its also a little faster than a Ryzen 3600 while still being a 65 watt part. Both the X570-P and X570-Pro motherboards have 4 memory slots. I have to use 4 x 32GB sticks to get to 128GB of memory. To get ECC memory support I have to use an X series CPU. The ones with graphics (the G series) don't support ECC memory, hence the need for a graphics card.
