possible OC with FX8370E and M5A78L-M LX V2

post #1 of 2
Thread Starter 
Olá pessoas.
Hello everyone.

recently i've bough a new CPU for my pc and I was willing to overclock it a little.
however, I am a noob in this type of things and i'm afraid of "blowing something up"...
my setup:


cpu: FX 8370E
gpu: Gtx 970 4gb
RAM: 8 gb 1600mhz corsair vengeance
mobo: M5A78L-M LX V2
psu: corsair cx500

so, my questions:
1-) Is it safe to do an "moderate" overclock? base clock is 3.3. I was thinking about 3.9, 4.0 max.
- the "amd turbo core" tech boosts up the clock to 3.6 (18x multiplier), but still shows in cpu-z that is between 7 - 21 multiplier. So I was thinking that 3.6, 18x maybe is the max boost while maintaining the base vcore.
- some people say that my mobo isn't very good to do it, and it would be better to let everything in "auto". But the max tdp is 125w, and the fx8370E is labelled 95w. Just raising a little of the vcore to get and 3.9 or 4.0 stable OC will or can really damage my hardware?
- if it is safe to do without "destroying anything", how should I start? i'd appreciate to OC just by the multiplier, not messing with ram or anything else.


Thanks!

Your motherboard is 4+1 phase, unheatsinked and with 4 pin auxiliary power connector. All this, "screams" not an overclocking motherboard.

There is always a risk when you overclock and the risk is greater when the equipment is cheap. Your motherboard, officially supports 8350, so, if you want to take the risk, you can overclock to 4Ghz, undervolted.

- Disable Turbo, APM.
- Raise multiplier x20
- The vcore, you should put it as low as possible, while remaining stable. Usually, all normal 83xx chips, can do 4Ghz@1.28v. The 1.28 is value under load inside windows. In the BIOS you may need to put a little higher (to compensate vdroop). Since you have 8370E, which is newer chips, it's likely, that you will be able to get lower voltage still. Like 1.26v. You need to try and see.

To see "quickly" if you are stable, run IBT AVX at Very High (don't use "standard", it's too easy and unstable).

Go as low as possible with the voltage. Once you pass IBT AVX Very High, normally, i 'd reccommend to run Prime95 overnight. However, given that your motherboard is feeble, don't. Just pass IBT at Very High and consider it good.

If you can add a small fan to blow air on the VRM (the area between the socket and the i/o shield), even better. Cause unfortunately, the mosfets are also older D-Pak type, which get hotter.

Good luck.


P.S.: Hardware failure is unfortunately following the rule of "all or nothing". Everything works, up until the moment that fails. Just because the motherboard doesn't blow on day 1, doesn't mean that putting it under stress won't take its toll in the long run. One should always buy hardware parts, according to the intended use. Your motherboard is more geared towards an office of HTPC use. Just because it supports 8350, doesn't mean it's "healthy" for it. 4Ghz are putting much strain on 4+1 motherboards. If you accept this reality and the risks, you can proceed.
