Hi,
I bought a Z600 motherboard off of eBay, and I didn't know about the bootblock at that time. So evidently I got the older, B3 revision:
AS#460840-002, with bootblock date 01/30/09.
After doing a lot of research I think I know pretty much all there is to know about it, so I decided to try and update the bootblock. I bought spare flash memory chips, Atmel AT26DF161 and a Raspberry Pi 3 B+ and I will try to write a fresh BIOS on it.
But still one thing puzzles me, I cannot understand why will registered memory not work on the older bootblock versions. The main reason for the confusion is that on the Intel Xeon 5500 and 5600 CPus the memory controller is on the CPU itself. Given that the difference between Z600 v1 and v2 is mainly the chipset, one being stepping B3 the other C2, what is the connection with the support for registered memory? Is it really the chipset, B3 not supporting registered ECC memory?
I have already asked this question on the Intel support community here:
No ueful response, so I thought I should ask here too. Can anyone give a technical response and shed some light?
I guess the main reason I'm asking this is to understand if upgrading the bootblock will do it, but otherwise I would just be happy to learn about the architecture of the system and where is the limitation.
Thank you!
