I have OC'ed it in the past, so it's not that. Thanks for trying to help(!), but I managed to fix the issue on my own. After bunch of tests with different variations (won't write them all), it seem like the "Core Performance Boost" option was the problem. Whenever I tried to OC when it's on, it didn't boot and gave me the "0C" error. The only way I could make the system boot is by clearing the CMOS. Without OCing and leaving it (core freq) on Auto, it worked fine even with Core Performance Boost on(default is on). But the only way I could OC successfully, was when Core Performance Boost was off. I hope this helps anyone who got the same issue.

I am not using RAID. Everything is connected accordingly since when I reset CMOS, it works just fine. If you've read my post, you must have notice that I did mentioned adding volts while OCing, and also mentioning that it is by far not my first time OCing. I've changed the ram freq to 2933 and it's volts without OCing the CPU, and it worked just fine. So it seem like just OCing the CPU is making issues. I still don't understand how the drives have anything to do with it.. Thanks for the answers btw, any help is much appreciated.

Huh...? It only happens when I try to OC.. How are the drives relevant?

So I cleared the CMOS and the system booted. Why did the error happen? It is definitely not my first time OC. Have I done something wrong tho? Should I try again? EDIT: I tried OC again and I got the same error. All I did was changing the freq to 3.8 and volts to 1.3250. Is this bios updated problematic? Why am I unable to OC? This is so frustrating

So I updated my BIOS just now to the latest, booted and tested and everything worked fine. Went back to the BIOS to oc the CPU and RAM, saved and restart and since then it doesn't boot. There are lights on the mobo and the CPU fan (AMD stock), all the fans but the GPU fans are working, and I get error "0C". The changes I made in the bios were: CPU freq 3.8, CPU voltage1.350V RAM freq 2933, RAM voltage 1.350 Timings: 16-17-17-17-36 (as shown on the sticks). That is all I did. Specs: Ryzen 7 1700, MSI x370 XPOWER GAMING TITANIUM, Corsair LPX 2x8GB 3000MHz C15, MSI 1080, EVGA 750W supernova. BIOS verion: 7A31v19 I've waited 10-15 min and it still did not boot. Turned off and on via power button 5 times, still did not boot. Mobo debug table shows that code "0C" means "Reserved for future AMI SEC error codes". Help please !

Anyone else has bright ideas? Any clues? This really doesn't make any sense..

The options in the power management section in BIOS are disabled (by default).. Btw, when it's on Auto and it's stable on 3200MHz(as I mentioned), one-three of the cores in a random order occasionally jumps to 3750MHz for 0.5 second. It's not related, but I am also a bit confused about that. Obviously my biggest concern is the fact that I am unable to overclock atm.

The value is not moving and is stable at 1550MHz while running CB and while runnning AIDA64. My power plan in WIN is on High Performance. It says that 3500MHz is max, but it never reaches that. It remains on 1550MHz idle or on load.

Idk, I hate updating to beta BIOS versions.. Wonderful member of our community you are. Thank you.

I did change it to default settings (Auto), but I obviously do want to OC for better performance.. I did check it and it gave I think just 1 more option which was irrelevant for my situation.. This is very weird.. I really hope someone with enough experience/knowledge will be able to think of a solution.

That's true, which is why I actually did try to disable both, but nothing changed.. =\

Core performance boost should only change how much more it gives, not that it should downgrade the freq.. Downcore is related to the amount of cores, not the freq.. Game Boost Function Control - Still not 100% sure what it does, but I am quite sure that it says that it can only be enabled/disabled through the button on the MOBO it self, and I did not touch it so.. Any genius idea out there guys?

sorry, forgot to add the BIOS screenshots. Any ideas? I've never experienced or heard about this issue before.

Specs: Ryzen 7 1700, MSI x370 XPOWER GAMING TITANIUM, Corsair LPX 2x8GB 3000MHz C15, MSI 1080, EVGA 750W supernova. CPU Freq was on Auto and gave me up to 3200MHz (with Auto voltage up to 1.2V or something), RAM was on 2133 or 2333(can't remember) and Auto timings. So, I ran CINEBENCH R15 + AIDA64 stability test for 10-15 min and it all worked fine. Then I changed the RAM Freq to 2933 and put the correct timings and voltage as shown on the sticks (16,17,17,17,36 - 1.36V). Ran CINEBENCH R15 + AIDA64 for 10-15 again, worked fine with no issues/instability at all. Then I changed the CPU Freq from Auto to 3400MHz and 1.30V. Loaded everything up, then looked at HWMonitor and it shows Min-97MHz, Max-3500MHz, Value(current freq) - 1550MHz. I ran CINEBENCH R15 and it still remained on maximum of 1550MHz. Checked CPU-Z and it shows Core Speed 1550MHz, Multiplier x15.5. For some reason, its only using 1550MHz instead of 3500MHz. Could anyone shed some light over here? I am so confused.. **I did update to the latest BIOS. **I tried 3.4GHz aswell, but got the same result.

Thank you friends, I really appreciate it! Have a great day!
