HP Z820
Microsoft Windows 10 (64-bit)

Dear All,

I am confused, nothing new. After following the excellent post on "HP Z820 Blue light, fans at max, no boot after CPU upgrade" I purchased two paired E5-2667V2 3.3 and a motherboard AS#618266-003 believing that they would work, but I get the fan max speed and no post anyway. I tried resetting the CMOS by holding down the yellow button for ten seconds with the power cord unplugged, to no avail.

Anyone have any ideas on where I have gone wrong?

I'm not sure if you actually have the V2 motherboard (2013 Boot Block Date) to support the V2 processors. Please read this post.

HP Z620 - Liquid Cooled E5-1680v2 @4.7GHz / 64GB Hynix PC3-14900R 1866MHz / GTX1080Ti FE 11GB / Quadro P2000 5GB / Samsung 256GB PCIe M.2 256GB AHCI / Passmark 9.0 Rating = 7147 / CPU 17461 / 2D 1019 / 3D 14464 / Mem 3153 / Disk 15451 / Single Threaded 2551

Thanks Brian, I am going to find a -004 as they seem to always support the dual v2's. Best of all.

board rev is not a definitive method of determining if the board supports ivy bridge (v2) cpu's only the bootblock date will
