Hi,
I been really trying what I can to find the issue but I am completely out of ideas by now.
It's a bit of a long topic, so I post the core issue first, then all the details thereafter.
Specs: AMD FX-8350 @4.8 GHz /w 1.45v, Asus Crosshair V Formula-Z BIOS 1503, Mushkin 2400MHz ram, pls see sig / below.
My system is running fine, but I do get sporadic (cold) boot issues:
I (cold) boot my PC, but after a few seconds power on it just shuts off again. ONLY thing I have found to work is to reset, after which system boots with message "Overclocking Failed! [...] Memory OK! succeeds in system booting! [...]". Then I need to load defaults (F5), then save F5-settings and reset, then go into BIOS and load my usual OC settings and it boots as normal. If I skip the F5-step, I get no boot either.
Sometimes I been working a couple of days just fine, with reboots and system being off in-between, then after a next (cold) boot the system just shuts off again a few seconds after I power it on. When I get this issue after a few days it freaks me out, as I though to have 'solved' it, but apart from running everything on F5-default settings, I get this error sooner or later.
I have no idea why this is, given my OC settings work every time when loading those OC settings from F5-default values.
I know that CPU 4.8GHz and RAM 2.4GHz is stretching it a bit, but as far as I am concerned it works fine usually. I understand that it is not 100% prime95 Blend stable, but that should not prevent it randomly from booting, especially when it boots just fine usually OR after loading my settings from F5-default!
😞Further details:
1) Settings are usually working. I can boot into Windows, I can play games, run prime95 FFTs - I been tweaking the BIOS to get this working and it's been working for the last couple of months.
Windows never crashes, however with the ram at 2.4GHz and CPU at 4.8GHz i get sporadic errors e.g. with prime95 Blend which I never entirely got rid of, but again it does not crash and works just fine. I have no idea if this could be at all related to the sssue, given the system is running fine usually.

- Memory timings are based on Mushkin profile, secondary timings are based on DOCP profile (written down and then saved)
- Issue also occurs with 10-12-12-28-AUTO
Anything, any ideas is more than welcome!
😕Thanks!
