What is the most current part no. for the Xeon V2 enabled motherboards in the Z820's?
Foolishly, I had read the Z820's could be upgraded to the Xeon v2 processors. I bought an E5 2680v2 and 32 Gigs of Ram. Installed the v2 and ram, same issue as others have posted previously - high speed fans and no boot.
Replaced the v2 processor with the original and the PC boots like a charm.
I've also read in another post that changes need to be made to the bios after a new motherboard is installed -
"When i got a replacement HP Z210 motherboard, it needed to be prepaired for service by adding some basic data to the BIOS. The data that needed to be add was model name, product name, serial number, build id and featurebyte. Such data can be found on the HP stickers on your machine and are specific to your machines configuration. Normally this is done by the HP technician that replaces the motherboard under warranty."
I found this motherboard part # 619562-001 but have no idea if it has the later (2013) bootblock date that would support the v2 processor.
Having already spent over $2,000 on the v2 processor and Ram, the idea of buying a new PC and throwing away that money isn't very appealing.
I don't entirely blame HP for the problem. When the Z820 came out, there were a number of glowing reviews about the system. All of those reviews I read noted that the Z820 could be upgraded to the new v2 processors and stated they had verified that information with HP - even quoting HP sources. However, I do believe HP is to blame for not clarifying that only Z820's with motherboards built after a cetain date would be compatible with the update. (I had a somewhat comparable situation with the new Sierra 2500HD I bought last year. My truck had the old style manual folding trailering mirrors. The "new" trucks manufactured after August, 2014 came with the "new" power folding trailering mirrors. Although the new mirrors were coming in on trucks on the lot when I picked up my truck, GM said my 2015 Sierra couldn't support the new mirrors in the truck's software. Fortunately a thread on the GM forum provided a means to install the new mirrors and actually have them work correctly. Only problem was GM wanted over $1,000 for the two new mirrors - they were @ a $250 GM option.)
I'm disappointed HP to my knowledge, has never come out publically clarifying this issue.
I have an early 2009 Mac Pro tower that - through a non-Apple support forum, came up with a method to "update' the early 2009 Mac Pro, which is technically a model 4.1 to a 2010 model 5.1. The 4.1 models don't support newer Xeon processors the 5.1 models do. So I was able to upgrade from two 2.26 Ghz quad core Xeons to two 2.93 Ghz six core Xeons. A much, much simpler process than what appears to be facing me with the Z820.
