Overclocking FX 4300 higher?
Overclocking FX 4300 higher?
Hey everyone! I've been running tests all night and all day today (which is currently 8:30 pm in Argentina), focusing on overclocking and stabilizing my CPU.
I'm using an Fx 4300 with a Cooler Master Hyper N620 (push-pull configuration) and an Asus M5A88V-EVO board. I'm running at 4.9 GHz and 1.4625 on vcore stable, tested with both AMD Overdrive Stress Test and Prime95 for four hours each. My maximum temperature reached was 59°C.
My questions are:
- Is this configuration working well or is the vcore too high?
- Just a quick thought, do you think I’ve won the silicon lottery? I read online that pushing this chip above 4.45 GHz on air cooling is uncommon, and some people need around 1.5 vcore to hit 4.7 GHz—what do you think?
- Lastly, if I manage to get lucky, how much should I push the CPU further? And what’s the safe upper limit for vcore before things get too risky? I tried 1.5 vcore and got a stress test of 61°C—was that acceptable or do I have more room in the thermal budget?
Thanks all!
Hmm I could push 4.6/4.7with 1.45 and be stable. Dang I just got an average chip. And the h5 is arguably much better than the 212 EVO. Temps are below 55c on highest stress tests, I would need chipset coolers if I were to go farther than 4.8, but dang. You probably win the lottery if you can get that high. HVe you used Intel burn test and occt, Aida64? Prime95 isn't that great. Check what the temp is. There is a difference between core/socket for AMD. 62 max for core and 72 for socket. Life decreases going over 1.45/46 volts. But dang, again
If your FX-4300 runs at 4.9GHz with under 1.5V, you've definitely secured a great performance. Share your other configurations. I'm using an FX-8350 at 4.7 (1.425v), but it's limited by the EVO 212 Push-Pull cooler and can't reach stability for other Piledriver CPUs. (4350, 6300, 6350) 4.6GHz was the top result for my FX-6350.

If your FX-4300 runs at 4.9GHz with less than 1.5V, you’ve definitely succeeded in getting the silicon to work. Please share your other configurations. I’m using an FX-8350 @ 4.7 (1.425v), but it’s limited by the EVO 212 Push-Pull cooler. I’ve never managed to stabilize any of my other Piledriver CPUs beyond that. (4350, 6300, 6350) My FX-6350 reached 4.6GHz was the highest I achieved.
Good work. Congrats.
I followed a tutorial to deactivate Cool & Quiet, Turbo clock, etc., then adjusted the multiplier to x24.5, set frequency to 200mhz (which was standard), enabled DRAM auto, and manually configured the vcore at 1.4625. I used AMD OverDrive to determine safe overclock limits per voltage, then increased it by 0.0125. At stock voltages (1.2500 vcore) I achieved stable speeds around 4.35GHz. My temperatures stayed between 60-61°C Celsius (rounded CPU at 59°C, socket at 61°C, peaking at 64°C). I was targeting a 5GHz boost but first checked here. If you need more details—full specs or a BIOS photo—I’m happy to assist!
I could achieve stable performance with 4.6/4.7 using 1.45 and it seems manageable. I just received an average chip. The H5 appears to outperform the 212 EVO. Temperatures stayed below 55°C during the most demanding tests, so I’d likely need a cooler if I pushed beyond 4.8, but that’s impressive. You probably have a good chance of winning the lottery with such a setup. Have you run an Intel burn test and OC? Aida64 works, but Prime95 isn’t very strong. Look at the temperatures—core/socket differences matter. For AMD, max core is 62°C and socket 72°C. Temperatures drop below 1.45/46V when going over 1.45/46V. But again...
Expect your CPU to fail early, possibly within a few months on a 1.55 or higher model. The issue with prime95 is that it isn't optimized to work well across all CPUs. It didn't perform well even after a day on stock. IBT is my preferred option.
If you adjust vcore to 1.5-1.6, the CPU's lifespan might be significantly shortened, potentially cutting its expected life by several months. It could also make the chip more vulnerable, so it's wise to avoid such changes if you're concerned about reliability.
So here it is. Around 1.45v-2-3 years. 1.5 volts, steady decrease in lifespan. About a year or more, possibly longer. 1.55v, near a year, maybe even just a few months. 1.6, roughly a month, possibly less. 1.65v, a few days.
Remember, every chip is unique and its lifespan varies too. The highest voltage AMD has built their processors at is 1.55v at the absolute limit. If you're aiming for longevity... But if you're just chasing records, I mean and if the cost of this chip isn't worth it...
I'll maintain the same structure and length while adjusting the phrasing.
