I've had a long standing email chain with AMD's support, but it ended up automatically closing due to a 2nd separate ticket being merged into the first that I didn't reply to. On the 2nd I submitted a new ticket, and have yet to receive a single reply to it.
The ticket number is #8201137769, and it's regarding my request for AMD to refund my Ryzen 5900x CPU. They have failed to provide me with a working CPU across 4 attempts, and nobody I talk to wants to admit fault even though AMD completed 3 RMAs. Most recently support has tried saying that a new, in box CPU supplied from AMD is not covered under their warranty, and instead claimed "we has authorized RMA more than one on a goodwill note."
When I attempted to confirm that my prior RMAs were tested and confirmed faulty, as outlined in the confirmation emails I received, I would get back vague and avoidant statements like "Before RMA approve we process the inspection and provide brand new unopened box product." and "Please to be informed shipment of faulty unit once received at warehouse, it will be tested and inspected at warehouse and the replacement part shipped." - All of this can be found in my prior communications on ticket #8201126869.
I have followed the steps AMD has provided to me several times. I have replaced the motherboard. I have swapped RAM with a friend's working Ryzen 3600x system, my RAM worked perfectly fine in his system and mine continued to crash with his. I have ensured I am running stock, default BIOS. I've ensured my RAM is not overclocked/ XMP enabled. I have set Power Supply Idle Control Typical. Windows is updated. My BIOS is updated. My chipset is updated. Every component has been reseated. My RAM is in the manufacturer recommended A2 B2 DIMM slots. My Windows power plan is Balanced (recommended). I've tried the voltage offsets. I've tried disabling PBO/CPB. I've tried changing so many BIOS and RAM settings as suggested across countless threads. I have done EVERYTHING and more a consumer should have had to, yet the WHEA 18 errors at idle persist.
I am not the only one with these issues, these forums were full of daily threads regarding "sudden shutdowns" and WHEA errors up until the Windows 11 complaints began taking the front seat.
I don't even care if support denies me the refund again. I sent an official notice as outlined by Consumer Protection Ontario, and I would like a reply either way so I can proceed through them instead if need be.
