FX6300 on GA-78LMT-S2 - Is it just a mild OC?
FX6300 on GA-78LMT-S2 - Is it just a mild OC?
I own a computer with a GA-78LMT-S2 motherboard. Of course, I know this MOBO isn't great for overclocking.
I recently upgraded from an FX4300 to an FX6300, which is useful because I often run screen recorders in the background and think extra cores will help.
However, I’d like to raise the FX6300 up to match the performance of the FX4300, without making any big changes.
I’m aware that the FX6300 supports speeds above 4GHz, but for now I’m only interested in getting it close to 3.8GHz.
I’ve checked a few forums about this topic and have a basic understanding of what’s possible.
My CPU cooler isn’t the standard model, but it’s not as large as the EVO212—it falls somewhere in between.
I use a big case called Phantex P400, equipped with three intake fans and one exhaust fan, which gives me solid cooling.
Additionally, when I’m gaming in my room, the air conditioner is running, so the room temperature stays low.
In short, I’m just curious if it’s feasible to overclock the FX6300 to the FX4300 speed using my current setup, or should I just go with what I think will work best.
I would give it a shot, but increase it gradually in steps of about 100 MHz and apply stress, using something like Ada 64 for 20 minutes. If it works, I’d keep monitoring the VRM temperatures constantly. I’d also set custom voltages, lower them slightly once stability is achieved, and test for around 12 hours to confirm everything is fine. Good luck!

I’d also adjust the custom voltages, lowering them slightly once a stable speed is reached and testing for around 12 hours to confirm stability. When you’re sure, test it for longer. This process helps determine the safe voltage limits before further adjustments. It’s still unclear whether the voltage needs to rise or if it’s just a guideline. That part about CPU overclocking has been really confusing—should the voltage increase automatically, or is it more of a suggestion?
Also, not to keep replying to my own threads, but technically speaking at full CPU usage, won't this one still run comparably to a 4300? The 4300 turbos at 4.0GHz, the 6300 at 4.1, so under load (gaming, multitasking, editing, etc) they should perform quite similarly, right?
as discussed, it's best to increase the speed gradually while testing. you should be able to hit around 3.8ghz on the stock CPU voltage. personally, even with the board I'm using, pushing it to 4 or 4.1ghz would help me understand the temperatures. anything above about 3.8 might require a slight increase in voltage. remember to turn off cool n quiet and turbo boost when overclocking. also, thinking about how the chips perform at high temps, i think a cooler component would be ideal. the 212 should suffice for light overclocking.
What is the stock VCORE voltage? I would adjust to whatever available on stock voltage, ideally under 1.35v, though that might be too high. I’d set up a fan to direct air onto the VRM and keep an eye on CPU turbo clocks for any VRM throttling, especially if the VRM is likely to limit the CPU. I don’t think you need to run a 12-hour stress test on an aging FX 6300 in a 4+1 phase board—it seems overly extreme. Unless the system could fail at all, I’d stick to shorter tests, like an hour or less, which should be safe with tools such as Prime95 26.6.
Stock VCORE voltage is what I'm looking for, aiming for no more than 1.35v, maybe even less. I might set up a fan to direct air onto the VRM and check CPU turbo clocks for throttling, though I'm not sure about VRM limiting in FX. It seems unnecessary to stress test for 12 hours on an aging FX 6300 with a 4+1 phase board—it feels too extreme. A short run of an hour should suffice, possibly extending to 15-20 minutes if the system remains stable in tools like Prime95. The VRM appears to be the main factor affecting performance.
I'm not sure about the turbo settings on FX. Just keep an eye on the CPU clocks; if they reach 4.1ghz and remain steady during heavy use, it shouldn't matter. I recall some features like turbo boost, cool and quiet mode, and core C6 that might lead to overclocking problems on certain systems, but they didn't really hurt performance. It seems stable as long as the CPU hits its boost speed and holds it under load. If it drops, it could be due to things like VRM throttling or overheating causing the CPU to slow down.

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 caused 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 stay 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.
