The 100MHz frequency change has minimal impact on performance. It won’t improve the design, add more cores, or significantly enhance SMT. The effort required would be high, so it might be wiser to focus on other activities like playing RE4 with a bit of lag.
I've already noticed the CPU usage in HWINFO around 90% or a bit higher, but it hasn't been tested for a long time—task manager also shows 100%. Probably I'm not getting much more out of it. Right now 4800AVX takes 5 cycles and 1.35v, but I still need to stabilize the GPU and RAM. I really want every frame I can get. Can I run LLC6 for a long time at around 1.33v? My PC crashed completely and restarted with strange sounds before it seemed stable again. It worked fine before. I'm currently using 1.35v LLC5 and need at least 4800MHz. Should I try setting it to 1.37v in BIOS? It looks like the core 1 is unstable—either way, the CPU stopped working, and there was a hardware failure back in 1995 with core 1. I think my CPU is being starved for power. In BIOS I set per-core frequency to 47, but it prevents me from setting core 1 to that. All other cores are stuck at 47. When I change it to 47 again, no workers stop. I've already set VCCIO and VCCSA to 1.1v. How can I free up power for the CPU? Should I try 1.36v too? It shows in BIOS as 1.341, but those readings don't seem trustworthy. Hardware failure is still suspected, and core 2 stopped... DAMN, I need at least 4800MHz! The current limit is 255.75—maybe lower the cache frequency to 4500MHz? What should I do? I need at least 4800, otherwise my CPU will be maxed out! Worker failures keep happening even with LLC6 and 1.35v.
You're risking damaging your CPU if you keep going at this pace. Instead, gradually raise your overclock in small steps and check for stability after each change before aiming higher. You already have issues on core 1, so adjust or reset existing settings and re-test. As @Mister Woof mentioned, the performance gain is barely noticeable—around another 100 MHz. It seems you're hitting the chip's maximum capability; either continue testing incrementally or settle for a stable speed and move forward.
I believed below 1.35v is safe! Even at 4700mhz, the worker halts at 1.35v, and LLC5 works too. How could it be so unreliable? Not likely that 4700 wouldn't help either. Need your help? It's odd that BIOS claims 4700AVX should function at 1.33v!
It's likely you have a chip that struggles with high overclocking. Even my 9600K never stayed stable above 4.8GHz at the voltages I tried. The brief moments it hit 5GHz didn’t make much difference. If you manage to reach around 4.7-4.9GHz across all cores, you’ll get the best real-world results from it. I noticed 4.8GHz was a clear upgrade over the stock 4.3GHz all-core, so I sometimes used that setting for more demanding games. I didn’t keep it on constantly because it generated excessive heat, and I thought the extra performance wouldn’t justify the trade-off most of the time.
I'm experiencing issues at 4700mhz but not at 4800mhz. The game demands high performance, especially for sniping which is very laggy. After playing for about two hours on 4700mhz with 1.335v and LLC5, I haven't seen any crashes. However, Prime95 froze completely, which is unusual since it usually doesn’t. Running the game at 4800mhz is extremely demanding; even at 1.35v with LLC5, it becomes unstable and causes overheating, reaching up to 85°C. The BIOS suggests around 1.37v, but I’m already overheating at that setting. It seems LLC5 might be the culprit. I’ve only managed about 72°C in-game on this configuration. I’m unsure if a cooler would help, as the system is already struggling. Perhaps lowering the LLC value could work, though it risks more heat. I’m considering adjusting Paradise settings and other parameters to see if they improve stability. Overheating concerns are high, especially with Prime95 stressing the hardware. I’d appreciate any advice on reaching 4800mhz safely or finding a stable solution. I value the graphics and atmosphere but need a reliable performance now. I’m planning a vacation soon and want to avoid further damage. Please let me know if there’s a way to hit 4800mhz without risking overheating!
Restore BIOS to default settings and keep XMP leave cache disabled. Set LLC to level 6, switch core mode to manual at 1.35V. Increase core clock by 100MHz and run R23 for a brief verification. If successful, repeat the 100MHz addition until you encounter an issue, then revert. Proceed to stress testing with Prime, AIDA, or a full workload—aim for at least four hours of continuous use. Adjust cache settings to match core (e.g., 4.4GHz) and run R23 again. Continue pushing until failures occur, then return to 100MHz and execute proper tests. Keep monitoring temperatures throughout. Once stable, reduce clock speeds by another 100MHz and lower voltage to achieve significant temperature drops for about 97% of performance. For a high-quality silicon like 4.9GHz core and 4.5GHz cache, expect around 4.8 and 4.5 maximum OC with optimal temperatures in the 1.3V range.
I noticed the problem too. At 175W TDP I'm already there, but my cooler is at 180W TDP. At 1.35V and using an LLC6, things get unstable—especially under load where the VCore drops because of overheating. It won't reliably stay above 4700MHz, and 8600kf seems to be the highest stable frequency I've seen for that chip type. From what I read online, only about 80% might reach 48/49 MHz... It looks like I got a really bad luck chip. Still, it's possible to hit 5GHz on a stock cooler sometimes.
