Hello. I finally got around to making an account here because I need some advice with whether or not overclocking will have any real impact on my performance, and if so, finding a good balance between stability and speed.


Here are my full specs:


Case: RAIJINTEK AENEAS (200mm fan in front, 2 120mm fans in back for exhaust)

CPU: A10-7860K @ 3.6 GHz

Cooling: Cooler Master Seidon 120V 86.2 CFM

MB: A88XM-A
PSU: SeaSonic SS500ET (Give or take 62 watts left unused)

RAM: Kingston HyperX 16GB (DDR3-1333)
GPU: SAPPHIRE NITRO+ RX 580 8GB Special Edition

SSD: Crucial BX300 240GB (For OS and important programs)
HDD: WD Black 1TB (For user storage/games)
OS: Windows 10 Pro


Notes:
-This is an in-progress upgrade of my first build, currently saving for a full system upgrade which will still take a few months.

-Drivers are all up to date, including BIOS
-Typically, my CPU only goes above 40 *C when playing a game, and my MB barely goes above 35, and the fans usually only run at half power.

-Pairing the A10 with a 580 worked better than it did with an A10 and R9 270X
-For what it's worth, I'm using cooler master thermal paste. (HTK-002)

What motherboard brand is it? I built a 7850k system on an ASUS board and only had to set it to "performance" mode to get 4.2ghz 3 years ago and it is still running fine.

A88XM-A is an ASUS board. It doesn't support 4 or 5 way optimization, just standard AI Suite 3. I have overclocking settings in my BIOS set to auto which hasn't really changed much as clock rate only reaches 3.7 which is still below its 4.0 turbo.


I've seen people reach 4.7, but I at least hope to hit 4.

I just looked and it is an ASUS A88-Pro motherboard. Your motherboard does not have any heat sinks at all on the VRMs so overheating could be a problem. So go for it and watch the temps.

4.7. I have a Crossblade Ranger, a UP4 and two A88X-PRO boards and I would consider that pretty unrealistic. Unless you want to pump like 1.52 volts thru the cpu. Hardly worth it.

Overclocked to 4.2 GHz as a starting point. On maximum load through stress testing, temperatures are stable at 47*C (CPU), and 37*C (MB).


What would be the ideal voltage and clock for this APU? I have tons of headroom due to decent ventilation and cooling.

On my 7850K on an MSI a68hm-e33 my bios has a boost clock setting
set that to 4.6
left everthing else default

Waayyyy to hot for my Hyper 212 to handle but the boost on Kavari is much better then the FX
Also I like that CnQ still works
Single thread score of 267 is equal to the 9590
Still deciding if I want to put a more expensive cooler on it or keep it in the 4.2 to 4.3 range
Obviously with your MB you will have a ton more options for OC'ing
edit:
An APU owners club would be nice :)

I'm new to overclocking, so I need a bit of help with this.


While my APU is stable at 4.2 GHz, I know for a fact that it can go higher, because I've tested it at 4.5 for an hour before I got a CLOCK_WATCHDOG_TIMEOUT blue screen, which I've heard can either be that the chip can't handle the frequency or there's just not enough voltage. I've seen people push it to 4.5~4.7 before, but I just don't know how they pulled it off.

Side note, I got a new RAM kit. Now using Kingston HyperX Fury Black, 16GB DDR3 @ 1866.

I know that, and what I said in my previous point only served to say that I always make sure that everything is up to date. There's no need to correct simple and trivial mistakes in language.

He corrected you as he well should have. Bios and drivers are obviously two different things and too assume you just made a "trivial mistake" as you call it would have been amiss on his part. So chill out and relax.

Thanks Chris, not picking on OP but trend in forums these days is starting to mimic the overreacting that goes on in MS social media today.

My board does not have it but my dau has an 88 board which has an LLC setting that can be set to extreme.
I would try that then see how high you can get the boost setting.

Then I would decide if you want to up the base clock.

It is soo much easier to OC compared to the FX and the boost clock is so much better. On the FX the boost clock only seemed to work in single thread.

Some MB's will let the cpu pull higher then the rated max cpu vcore.
I'm still learning myself, It seems that the APU needs much higher v-core then the FX
For some reason HWmonitor 1.29.0 seems to work better then the newer versions on the 7850k
AMD overdrive was totally useless for temps on mine

I use cinebench rendering test to see how hot it gets and these things get really hot really fast, Mine got to 79C before I stopped the test which was only 1/4 of the way through

That's very true with latest 3003 bios on A88X-Plus mobo. The Vcore diff between 4.0Ghz & 4.1 & higher is stupidly ridiculous if left on auto, I'm talking 1.39v V 1.44v & the offset increments, even if manually starting from lowest value are way overestimated by this mobo.
Amazing simple things like that they stuff up at Asus!

Higher Vcore needed on A10 APUs has got to do with iGPU sharing same silicon. Its obvious the limits of 28nm fab have been reached with concept of SOC.

Using HWmonitor 1.35 with no issues.

Luxmark pumps up the heat n' stress testing phenomenon. One's temps will depend on many variables.
