FX-8320 with asrock extreme3 r2.0

I was looking into overclocking my cpu (FX-8320), but I'm seeing things that say that overclocking with my mobo (asrock extreme3 r2.0) doesn't do so well. However, there are other people saying that it's possible to do so, and at around 4ghz.

So if I'm able to overclock, how far will I be able to go (speed and voltage)?

read forum rules if you have that sort of question.

Your motherboard has heatsinks for the VRMs and northbridge chipset, and has an 8pin PCU power plug.

Id say you are good for going to 4GHz no problem.

You have a disadvantage though. your cpu is a 125watt TDP. if you were on a 95watt TDP 8 core you would have a bit more success

you can hit 4GHz easily though. go into BIOS, disable turbo and cool N quiet and any power saving modes.

Then set your cpu to its turbo voltage. cpu-world lists your cpu as 1.425 volts.

If you set 1.425 volts, set your multiplier to 20x, you should be at 4GHz. stress test to verify it is stable, and WATCH YOUR TEMPERATURES

HWinFO64 reads a lot of temperatures, is free, and a great tool to see how high the temps get.

use interburntest, should have agent GOD somewhere on it, it is the correct version to use. majorgeeks should have a download for it

EDIT once you find it stable, you can then drop voltage one tick, or to 1.415 if you have manual input available, and retest. the goal is to lower voltage at 4GHz so you can reduce heat and stress of the motherboard.

I assume ASRock Extreme3 970?
If so, the VRMs leave much to be desired. It sounds like what others are telling you is accurate to a degree. You could get a little extra speed out of your chip, but I wouldn't expect much. It is also likely that your board will also encounter heat issues as well. Stress tests will no doubt bring it to it's limits quite quickly but while doing your usual tasks (including gaming if that is what you do) you won't see the temperature issues as often or quickly.
If we are talking about the board only, it should get you to 4GHz and maybe to 4.2GHz or so, but it will be difficult.
But, we have to also see what other parts you have. What is your PSU and CPU cooler?

I went for 3.7GHz first, and saw in open hardware monitor (already installed) that "Temperature #1", which looked something like this:


hit over 78 degrees while running prime95 (already installed).

Is this okay, and should i oc higher?

EDIT:
I guess this is important as well, cpu core temperatures hit 60.8 degrees maximum

Depends from board to board. Considering it's a lower to mid ranged board, I'd say don't push it any further or let it stay that hot for long. I'll see what I can dig up on ASRock 970 thermal limits.

Update: Looking at the board again I realize I have miscounted and over estimated the ability of the VRM. This is a low end 4 phase board. Running a 8-core FX at stock is essentially this boards limit. Trying to get anything more is quite a task.

I had that board! Got my 8320 to boot (only with 4 cores enabled) at 5022mhz and was able to get in a few Super Pi runs

3DMark and anything more demanding I was limited to 4.8 with all 8 enabled due to temps but as long as your case airflow is okay, the board really isn't as bad as some of the people here are making it seem.

I'm pretty sure it's just my cooling that's preventing me from going over 4GHz, I may have to look into that.

I'm still sort of concerned about the "Temperature #1" sensor, some people are saying its the cpu socket and that it shouldn't go over 70 degrees. I also noticed that it's under a thing called "Nuvoton NCT6776F", if someone could tell me what it is

Be sure to cool down your VRM´s to avoid toasting problems. Just put a fan blowing air in the heatsink and you are good to go !

With your motherboard i believe 4.2Ghz is viable and easy job.

I use something like this !


Remmenber cool down your VRM´s, you will be fine !

Is the VRM "Temperature #1" on open hardware monitor?

I believe it´s socket temp´s !

jclafi, his board is barely equipped for adequate delivery of 95W, overclocking a 120W TDP processor is not something he will want to do without shortening the lifespan of either the chip or board (or both).

why does it say i7-3820 in this screen grab?

speed and voltage dont really match a whole lot either. Perhaps accidentally grabbed from a different computer?

This motherboard is very capable of making any 8 core run 4ghz. Either your ambient is quite high, or something is misrepresenting voltages and its actually quite high.

a stock boxed cooler for an fx6300 could keep 4ghz 8 core cool enough to run.

yeah, that's not mine

I'm just looking for the maximum socket temperature for my cpu and board, nothing else
