FX6300 on GA-78LMT-S2 - Just Mild OC?

[MetalMatty]

So I have a computer that runs a GA-78LMT-S2 motherboard. Yes, I know this MOBO sucks balls for O/Cing.

I just went from a FX4300 to a FX6300 (I constantly have a type of screen recorder running the background so the extra cores should help with everything). BUT, I would like to bump the FX6300 just up to where the FX4300 speed, so nothing major.

I know the FX6300 can handle 4GHz+ speeds, but I don't care that much for that, I just want to push it to 3.8GHz. I've read a few forums and such on O/Cing, so I have a pretty basic understanding of it.

My CPU fan is not the standard one, but it's not as big as the EVO212 is, it's kind of a middle ground. I have a large case Phantex P400, with 3 intake fans and one exhaust fan so cooling is pretty good. Plus, any time I am in my room gaming my A/C is on so ambient temp is pretty low.

I guess really I am just wondering if O/Cing the FX6300 to the FX4300 speed would be possible with my MOBO or if I should just accept the lower speeds and hope that my theory of the extra core helping with the recording software is correct.

Case: Phantex P400
Motherboard: GA-78LMT-S2
Graphics Card: Zotac 1060 6GB Amp.
PSU: 750W EVGA
CPU: FX6300 w/ slightly larger than stock Cooler Master cooler.

I would try it, But only bump it up buy ~100 mhz at a time and stress it, with something like adia 64 for 20 minutes.

If it supports it, I would also be constantly looking at VRM temps.

also I would set custom voltages, and when you get a Speed thats acceptable, bump the voltage down slightly and test, when Its stable, test it for 12 hours or so to make sure its ok, good luck!

So, while upping it by 100mhz at a time, how do you know how high it can go? Pretty much until the program or computer crashes, then back it off another 100 or 200 mhz?

At that point, if it's stable at whatever setting it's at, do you NEED to raise voltage, or is it just recommended?

That's the part that so far has really confused me with O/Cing a CPU, is whether the voltage -needs- to go up, or if it's a recommendation.

Also, not to keep responding to my own threads, but technically speaking at full CPU usage, won't this one still perform relatively equal to a 4300? The 4300 turbos to 4.0GHz, the 6300 to 4.1, so realistically under load (gaming, multitasking, editing, etc) they should perform fairly similar to each other, no?

like was said,bump it a little at a time testing in between.you should be able to reach 3.8ghz at stock cpu voltage.personally,even with that board i would push it to 4 or 4.1ghz and see what temps i have.anything over about 3.8 will probably need a mild boost to cpu voltage.make sure to disable cool n quiet and turbo boost when overclocking.also,considering the temps those chips can push,i would find a little better cooler.the 212 should be good enough for mild oc.

What is stock VCORE voltage? I would OC to whatever you can get on stock voltage, whatever that is. Certainly no more than 1.35v I would say, that might even be a bit much. I would personally rig up a fan so it blows air down onto the VRM and monitor CPU turbo clocks for VRM throttling, if that VRM will even throttle the cpu, not sure on FX.

I don't think you need to stress test for 12 hours on an aging FX 6300 in a 4+1 phase board, seems a bit extreme to me. Unless that computer cannot crash for any reason and you want to be sure it's totally stable. I would do an hour at most, personally I would do 15-20minutes if it doesn't crash in something like Prime95 26.6 it's likely not going to crash in games.

Stock is 1.35. From what I've seen in my research, the VRM is what limits this mobo the most. I am hoping that with 3 intake fans it keeps it cool, especially for the low OC that I want to do.

I guess another thing I'm curious about, if I just leave turbo boost set to 4.1Ghz and raise base speed to 3.8Ghz, is there going to be any actual benefit? Or does most of the benefit from OCing come from turning turbo boost off and just having the CPU run at a constant speed?

I forget how turbo works on FX. Just monitor CPU clocks, if they go up to 4.1ghz and stay there when the CPU is under load then it doesn't matter. I do remember some of those features turbo boost, cool and quiet, and core C6 state to name a few could cause overclocking stability issues on some systems but I don't think they affected performance. Not if the CPU goes to it's turbo boost speed and stays there under load, if it drops it could be one of those features causing it particularly cool and quiet, VRM throttling, or CPU throttling from overheating.

I guess that is one easy enough solution. I'll run a stress test all stock and see if it's able to just hold out at 4.1 GHz. If so, then I just won't touch it all.

Sounds good to me.
