probable faulty i7-4790K cpu | 2026-05-17T06:42:13 | 2026-05-17 |
recently setup a on site 'pve-block' with a bunch of HGST Ultrastar 7K6000 Series 4TB SAS HDD (x10), and last 2026-05-16 noticed that my gigabit network wasn't being saturated during OpenZFS send/receive. Proxmox was showing significant cpu/io stall pressure, probable diagnosis; my old Intel Core i5-4570S CPU was struggling to keep up this fairly easy task. I've had this cpu from new and it's been used in various builds over the years with no issues at all, However, now it looks like it's finally reached the end of it's useful life.
I've still got a Intel Core i7-4790K CPU which should quickly solve my issue, but when I swapped them, the computer failed to boot using my ASRock H87M-ITX Motherboard. Which was strange because I'd only just removed it from this itx board (with the same memory) in favour of the more power efficient i5.
I also had this recent 2026-03-31 1758 faulty gryphon z87 motherboard (nothing to do with this, ) ASUS Gryphon Z87 Motherboard was faulty. the hardware setup at that point was:
- Intel Core i5-4570S CPU
- ASUS Gryphon Z87 Motherboard
- Kingston HyperX Genesis 8GB DDR3 RAM (2x4GB kit)
the failing setup last night
- Intel Core i7-4790K CPU
- ASRock H87M-ITX Motherboard
- Kingston HyperX Genesis 16GB DDR3 RAM (2x8GB kit)
there's no cross over there
