HP z820 CPU options include various processors suitable for different needs.
Hello everyone. I just acquired a simple HP Z820 workstation at a very low cost and plan to upgrade it into a powerful dual Xeon configuration. It features two 2011 sockets that support both E5 and E2 Xeons. I’m familiar with the 26xx lineup but also see the 46xx models, which can sometimes be found for a fraction of the price. A pair of 4650v2s would look great compared to a set of 2680v2s.
I’m curious about this – does the BIOS require specific microcode for each CPU model to function? If yes, does that imply only CPUs listed on the HP Support List for the Z820 will work? Can I modify the BIOS and insert custom microcode to enable support for a CPU like the 4650v2 if it isn’t natively handled?
The Z820 uses the C602 chipset instead of the X79, so Intel XTU won’t be an option. HP doesn’t offer overclocking settings in the BIOS, and aside from a few select 16xx chips, these E5/Xeon models are locked. I’m wondering if there are any hacks, workarounds, or modifications that could allow moderate CPU overclocking on this system.
The system does not support any NO 4600 CPUs, though users have noted they function properly. Performance enhancements like overclocking aren't possible—only stock configurations are available. What is your main purpose for using this setup? You usually choose higher clock speeds or more cores, but not both at the same time.
They mentioned they won’t be available. I’ll likely purchase a couple of 2650v2s since 2667v2s cost a lot more.
