Greetings to all of you nice community at tom's hardware!

My specs:
Fx 8370e (base clock 3.3, auto oc 4300)
Msi 970 gaming mb
Corsair vengeance 1866
Cooler master 240 water cooler

Problem was that i noticed cpu throttling at 50C (even with that cooler, believe??) So i decided to reset it to default clock in these hot days in Holland. Well it didn't default. It's always overclocked at 3600 4.480 vcore (believe this shitty factory overclock?) Tried everything. Jumper. Battery. All. Cmos clears but cpu doesn't default anymore like it used to. I've managed to get a better temp at lower voltage and higher rpm for now. It seems like overclocking is my only option. Miracles never cease. Any ideas?

What I know is the only way to truly learn to overclock is to learn your bios. That 0. is percent of a volt. As in 0.15 to 0.2 to 0.25 to 0.3, ect.

Overdrive starts with Windows. If adjustments are made in the bios they start before Windows actually loads.

@lakimens i'm not versed in overclocking. I used the oc genie formula and only down clocked the voltage to save the situation. I'm not sure 1866 ram runs at stock 3300 on the cpu and on this mb if that makes even a lick of sense because originally in the bios oc settings the memory always ran at auto 1333 for some stupid reason. The issue kind of came about when when i changed that 'auto' to 1866 to get my dollar's worth.

That requires a whole day of experimenting with clocks and voltages and i'm not sure i can face any boot failure or go without this computer for days. I'm just trying to wrap my head around what's happening with it before i regroup and go further. I would like to find a reasonable overclock with a speedstep eventually because it just isn't reasonable or necessary to run my clocks, voltage, and fans at full speed all the time.

@thepaladin
thank you for your reply.
i cleared the cmos many times by placing jumper and by removing the battery. i'm sure it cleared because i had to reset windows clock and date. nothing changed. cpu still has 3300 as target speed in AMD overdrive and 3600 as current speed and no cool and quiet configuration (i never enabled or disabled it manually). there's one option in the bios that says 3600 under turbo core clock technology. tweaking it through AMD overdrive to 3300 will not make the cpu go back to stock but it will act as an overclocked cpu at clock speed so the voltage is fixed and the speeds are always the highest on the clock while at stock settings it used to lessen the voltage when on idle. i just wanna make sure nothing funny's going on with the cpu or board.

status update:
I think CPU overheat was not the issue. I suspect the motherboard is overheating somehow because when i turn up the case fans (i have 5), prime95 runs smoothly at 4300 1.3 vcore for an hour and cpu temp never crosses 42. TMPIN1 reaches 83c reported by HWmonitor pro. interesting to note, I played Dying Light the Following when the fans were not turned up as in the stress testing and it played a constant 60fps. I guess prime 95 unnecessarily stresses computer. no real world scenario is even going to stress the cpu to a 100% even for 10 minutes.

status update:
maybe both the mb and cpu can't take 4.+ voltage because when i ran prime95 the cpu throttled at 51-52 and then i tweaked down the voltage to 1.3125 it didn't throttle but i had the fans (5 fans) turned up to a 100 and the case panel was off (amb temp 25). then i put the panel back and turned the fans down to drown the noise, lo and behold it made a fatal error in rounding while running prime 95. after that i turned the fans back up and ran the same test for an hour and at lower voltage (1.3) and it ran smoothly.
nutshell, mb overheat is real and should be taken into account.

Vcore voltage should not be above 1.5v, the lower the better. If you truly at 4v+, then something is drastically wrong and you are headed for catastrophic failure as the motherboard and cpu are in no way designed for that kind of voltage/current/heat.

@Karadjgne thank you for your reply. I didn't design the overclock, It was oc genie doing everything. All in all, I got stuck with the CPU not going back to stock. However, I ended up achieving very good vcore (1.3125) at turbo overclock 4.3 GHZ. I switched the water cooler after it started leaking thanks to cooler master, and got a Noctua D14 instead if it. I'm achieving 25-30 on idle and up to 51-52 after an hour of Prime95. Bear in mind that it's hotter than satan's balls celcius out there at the moment. I'm actually going below ambient on idle. I'm a little bit upset the CPU is not going back to stock and worried it would give me more trouble since I don't know the cause and implications of the issue, but i'm enjoying a good overclock and playing games at highest-ish settings delivered by my overclocked RX 480.

Well not to burst your bubble, but it's physically impossible to cool a cpu below ambient temp by mechanical means, such as a cpu cooler. In order to go below ambient you'd need to use chemical means, such as LN2 or peltier. Which means your software is suspect or the sensor is.
With Amd FX, your best option is Amd Overdrive for temps. How it works is that there's a temp limit on the cpu and overdrive reads just how close to that limit you are. So if you see it registering close to 0 then you have a very hot cpu. If you ever see negatives, you are well into damage causing heat ranges, start expecting the cpu to throttle back or shutdown. So you won't see an exact temp as such, just how much room you have to work with left. Overdrive is the only somewhat reliable temp software for those cpus.

I'd advise you do some research on your motherboard bios settings, OC for your motherboard, cpu (any FX 8 core is the same) etc and learn how to OC manually. Leaving it up to software OC via OC genie is a fools game, it'll do what it wants and not tell you just how

I heard of that in a lot of places and i've been monitoring the temps. right now it's 49 on the thermal margin. ambient is 17-19 so i'm only a few degrees above ambient. on core temp and hwmonitor, sometimes the registered temp is even below ambient. the point is the temps i'm getting are very reasonable for an overclock. I didn't even try to push it further which i'm sure I can but I just don't need to do that currently. I would like to learn how to do a manual overclock later on because i'm seriously beat with the stuff I had to learn to build this bitch, pardon my language.

CoreTemp was written for Intel cpus, so that's not surprising. Overdrive is what should concern you. The Thermal margin will let you know exactly what the cpu is up to and where it can go. Actual temps are nice to have, hard to get on amd cpus. But temps are useless without a frame of reference. If you figure most Intel are good for 100°C max, at 70°C you are getting precariously close to throttling. Easy, no brainer. Your FX cpu has a max temp of just 62°C, but due to design of the Thermal strips in the cores, that's impossible to accurately read by any software, and physical means can't, the cooler is in the way. Generally, you find package temps of low 70's are a better indicator of reaching 60's on the cores. But there's no gray area like Intel has, so that's where Overdrive comes into play. While it can't read the strips exactly, it's algorithms allow it to do all that thermal math hoop jumping and give you a temp that's relatable. And the margins aren't linear, it won't change 1° up or down with a 1°C change in ambient, if your ambient went from 19 to 22, that's 3°, but the margin could easily drop to 40 instead of 49. This is what makes Overdrive so much better, it's realistic value. It's an excellent tool for adjusting things like cpu cooler fan curves, case fan curves etc as you'll get a more accurate picture of what affects the cooler better.

I don't really understand all that but what I do know is that i don't think i will buy AMD every again. I'm just going to save up and buy an intel cpu and nvidia graphics card next time. this heat things has given me more hassle than columbus had when discovering America.

But hey since you have an msi bios, maybe you can teach me how to set the cpu voltage from bios. It's weird. The numbers are all like 0.23789 for example. So no clear numbers like overdrive. rn i have 1.3125 in overdrive but bios stteings are different. The numbers always start with 0+ or 0-

substitute "numbers for terms"

Layman's terms
The phrase "layman's terms" is often used to refer to terms that apply to the everyday person, as can the term "layman" or "layperson" itself. Synonyms for layperson include: parishioner, believer, dilettante, follower, member, neophyte, novice, outsider, proselyte, recruit, secular, laic, layman, non professional

Oh and by the way overdrive sucks and no one that knows what they are doing in the bios uses it. <=not directed at you.

So teach yourself and have some fun.

we all got it. you don't know the answer haha cheers mate. take it easy. i never claimed to be a pro. there's no pro overclocker except those bastards that use liquid nitro.
