overclocking amd fx-8120 question

[HypersleepyNaputunia]

Today i oced my chip to 4.3 ghz from its standard 3.1ghz/4.0ghz turbo. Running it at 1.275 volts with temperatures that seem pretty decent 53.5c.

Any advice on if I can keep running the chip this high 24/7 withouut damaging it. I could possible push it more but idk if I want to take the chance to go to 4.5 as I am only air cooling it.

Those 53°C are under stress testing?

If you're running a stock cooler you'll be very limited.

What cpu cooler is on it? You've got room to bump up the volts if it's at least a cm212 cooler

[upcoast]

Are you sure you're just pumping 1.275v to it because that seems a little high on the temp side for such a minimal volt.

If it's like a 212 evo or plus I wouldn't expect more than 40c-45c max on a bad day.

My 8350 1.36x volts with a old tuniq tower 120 doesn't push over 45c.

Regardless though you're under the 62c threshold and it's only 1.275v I wouldn't worry about 24/7 use.

CPU Temp is fine.
Keep an eys on the VRM on your board, those tend to get really hot with FX 8xxx CPUs.

They deliver the power to your CPU, if you encounter drops in CPU clockrate to about 1.4Ghz, they overheat and the CPU is throttled to prevent damage to the Board.

hwinfo64 can read out those informations for you.

That board is pretty good, lots of CPU phases with a huge heatsink.
Temps can go up to over 100°C, but that's no problem for a VRM, on my GA X79-UD3 with an OCed i7 3930K the VRMs go up to 90°C.

For your GPU: try raising the power target first, that allows the card to draw more power, then increase clockrate and when you get into temperature or stability problems, increase Vcore.

20% more clockrate is huge on a GPU, especially AMD.
My R9 390 runs on 1240Mhz core (1040 stock) and 1750Mhz memory (1500 stock), +50% powertarget, +85mV core but it is watercooled with a custom loop so I have way better cooling compared to aftermarket aircoolers.
Can't get the GPU any faster as I get reproducable crashen on games.

Get MSI Afterburner, go to settings, there you can unlock options for voltage settings.

Just change 1 setting at any time, run a game/GPU bench and if it works, do some more changes.
Clockrate till GPU runs unstable, creates artifacts, etc., then increase Vcore 10-20mV, and try again.

I used the build in benchmark from The Division but anything GPU heavy will do.(f.e. Heaven Benchmark).
Don't use furmark or stuff like that, just generates maximum heat, no power fluctuations or anything, has nothing to do with real-life situations like games.

If you have found your sweetspot, klick on "apply overclock at startup".

If you do use MSI Afterburner, first before you do, revert the AMD OC's in the AMD Software back to defaults. As you want to do it from AMD software or Afterburner; not both.

That voltage is fairly low for that OC; it's not unusual for AMD CPUs like that to need 1.35+ in order to be stable. Even at stock speed, those FX-8 series usually run upwards of my stated voltage without any OC, and generally need that to stay stable. I think maybe just need to up it a bit and re-try.

a little confused by raising power target. How would u proceed on this Sapphire hd7950 3gb? It has 2 cooling fans, I dont have a vcore option
gpu clock 925 (max 1200)
memory clock 1250 (max 1575)
power contol -20 to +20

youll need to raise the power target for stable overclocks about 1050ish for most cards especially at stock or higher vcore.. the 7950 is a great oc'er though had msi one back in the day oced+undervolted but even undervolted+oc required power increase of about 5% or so

you can get a pretty good oc without raising vcore on those cards just watch temps

Again with MSI Afterburner w/ AMD GPUs; first you will need to go back into your AMD Control Panel and Disable any OC in there first, before attempting to OC via other software. Otherwise the two will conflict and only one method any given time would work.

For app such as MSI Afterburner, also check the Settings and enable all those Compatibility settings; as well as changing the low-level access to Kernel Mode and put the Unlock Voltage Control on whatever best suits your GPU model. On most GPUs, especially AMD ones, you might not get Voltage unlock options if it is not an Extreme OC GPU model, so keep that in mind. However a voltage change on a GPU usually is never needed to gain a decent % OC increase anyways.

Some GPUs, the Voltage is locked, that's just how it is.
