Overclocking FX-6300 with AsRock 990fx-extreme3
Overclocking FX-6300 with AsRock 990fx-extreme3
Yes it can overclock, and may do it just fine, but I don't recommend overclocking on a board that's not rated for at least 75 watts higher than the TDP of your CPU... There's no real way of telling exactly how much power your CPU will draw when overclocked because of the "silicon lottery" which means that two processors coming off of the assembly line right after each other may not have the same microscopic defects as each other even though they're the same make and model.
AMD in general tends to get rather power hungry when overclocking.
However, I'm always looking forward to learning new things... If you can provide link(s) that prove that that board will overclock without power delivery problems then I'll be happy to take back what I said earlier.
The discussion highlights various suggestions and observations about overclocking, software tools, and system performance. It mentions recommendations from users regarding programs like CoreTemp and Hardware Info, as well as advice on using AMD Overdrive for accurate temperature readings. There are also notes on the effectiveness of BIOS settings and thermal margin adjustments. The conversation concludes with a request for guidance on running Prime95 at 4GHz and how long to do so.

He brings up a valid point that I somehow forgot about... HW monitor has given my problems in the past, I recommend a program called CoreTemp, but SR-71 Blackbird (a very knowledgeable user) recommends Hardware Info
For a forced air cooler, the idle temperature seems a little low, I think HW monitor is screwing with you.

So basicly OC-ing my CPU won't give me any boost (atleast maybe in gaming)
thats socket temp so it is actualy capable to be low 20's while idling in my experience.
theres some misinformation above aswell.
Both your board & cooler are eminently capable of fairly big overclocks mate- no doubt at all.
You should though be using amd overdrive & its thermal margin readout for core temps - its by far the most accurate & reliable software anywhere.

just dropping in bios,disabling turbocore & setting multiplier to 20 for 4ghz will give you a straight & noticeable performance improvement ,in gaming & other apps without touching any voltage etc
it will barely increase temps at all & will stop those irregular clock & voltage drops under load that turbocore causes.
straihgt prime blend test I would expect the thermal margin to be 30c or above while its running (the thermal margin actually works backwards from the cpu's max temp of 72c)
You probably have headroom up to & around the 4.5ghz mark with your components although 4.2/4.3ghz tends to be the optimum without increasing voltage exponentially.
& yes 4.2ghz will give you a noticeable boost in gaming performance although the 260x is more of the weak link in your system imo.
You also havent stated psu model which can also be important??
edit - seen the psu - not great quality but its enough & isnt really a concern,
Ok, so my cpu is now at 4ghz, I am gonna run prime95, for how long should I run it?
single standard run mate,4ghz isnt really anything - itll pull about the same voltage as at stock wth turbo enabled.
You are doing this in bios ?? please dont use software for overclocking at all,it pushes unrealistic voltages.
in all honesty looking at the board I am going to agree upto a point with weberdarren97 - it is not a great quality board,& ive wrongly assumed it has a 6+2 vrm set when it doesnt,it has the same setup as the old 970 extreme 3.
However 4ghz is entirely safe imo,Its still not going to go past a 105w tdp threshold .
I would be dubious about going past that without any added vrm cooling
Just keep an eye on amd overdrive for any signs of throttling,all clocks should stay 4ghz solid with no fluctuation.
I would also put cpu-z up onscreen & let us know cpu voltage under load while prime is running - there may be the opportunity to actually drop voltage a little even at 4ghz.

Yes it can be overclocked and might work well, but I wouldn't suggest it unless the board is rated for at least 75 watts above your CPU's TDP. It's hard to know exactly how much power the CPU will use after overclocking due to variations in manufacturing. AMD usually consumes a lot of power when you increase the clock speed. Still, I'm eager to learn more. If you have links showing this board can overclock without issues, I'll reconsider my earlier comments.
Looking at the specifications, I think I'll partially apologize and partially agree with you. But a 4GHz boost will be fine on that board.
A 75W rating above the installed CPU for overclocking is unlikely, especially with the 6300 which isn't very power-hungry. Its power consumption at small overclocks has always been exaggerated. You'll rarely see a 6300@4GHz drawing more than 90 watts max.
I also used Prime95 and switched to AMD overdrive to monitor temperatures. After five minutes, my PC froze briefly for 2 to 3 seconds, and then a blue screen appeared after seven minutes. What caused this issue?
voltage is likely to drop significantly, reaching a 19x multiplier. turbocore increases voltage to reach boost clocks, so disabling it will lower the cpu's voltage below normal levels—most 6300 models can handle this, but yours probably won't. try reducing the multiplier to 3.8ghz and run the tests again. let me know the voltage reading in cpu-z during the prime test. what were your temperatures while overdrive was active?
This indicates that your overclock is unstable, something isn’t working properly... Try lowering the clock speed by a few dozen MHz and reducing voltage by 0.005 volts at a time until the system stabilizes. If the issue worsens, adding voltage might be necessary. It’s a bit uncertain for me because I can’t see a screen showing the current clock speed or precise voltage readings.
Edit: Temperature... What was the temperature just before it crashed? Once it stops, restart into BIOS and check the temperature in BIOS—shouldn’t exceed 40 degrees Celsius.
The voltage is probably dropping, so lowering the multiplier to 19x (3.8ghz) might help. Disabling it will keep the CPU at a lower voltage than usual—most 6300 models can handle this, but yours won’t. Test again after adjusting and let me know the reading in CPU-Z during the prime test. Your temperatures in overdrive were decreasing quickly, from 38 to 45, so I plan to go back to 3.8ghz and run the prime test.

madmatt30 shares insights on voltage adjustments and performance.
Most likely, lowering the voltage to a 19x multiplier would help. Turbocore requires higher voltage to reach boost clocks; disabling it keeps the CPU at a lower voltage than usual—most 6300 models can handle this, but yours probably won’t.
Try reducing the multiplier to 19x (3.8ghz). Re-run the tests and let me know the voltage displayed in CPU-Z during the prime test.
Also, check your temperatures while overclocking. The thermal margin was decreasing rapidly from 38-45°C, so consider lowering to 3.8ghz and running the prime test.
Any temperature above 30°C is not a big concern as long as it stays under 10°C during full load—this is completely fine under 100% prime load.
The standard stock P-state voltage at 3.8ghz is 1.4125V, but you’re likely only hitting 1.3-1.33V under load, which isn’t sufficient for your CPU.
The main tab of CPU-Z will show the load voltage while the prime test runs—keep it visible.
after 30-40 seconds the core dropped from 100% to 8% (sorry for the background in the picture)
