Here is some advice for doing a small overclock.
Here is some advice for doing a small overclock.
I see you have room for more power because AIDA64 shows your heat at max 54C while under load. This is great. Now, increase the frequency by changing the multiplier and keep the Base clock (bclk) at 200MHz. We will try to get a 4600MHz target first. That equals BCLK of 200 times 23 on the multiplier. Try setting 1.250V for the core and SOC to 1.2V. If it won't start up, raise the voltage in small steps. Remember not to go above 1.375V on the core (this is very important). You have LLC which needs to be increased to level 5 because you are coming close to your target frequency. This stops any drop in power under load. Also set current capability to 110% for a stress test at each phase and watch your heat. Since you're starting out, do it in small steps (200MHz stages) so you can learn how the BIOS works. It's best to go slow, take time, and be patient to get the best result. As you near your goal frequency, keep checking the motherboard VRM temperature and look at the CPU heat using HWinfo64 because that is the most accurate sensor for your processor. Unfortunately I couldn't read your pictures clearly enough (they are blurry) and please send photos of the HWinfo pages if you fail at any point. There will come a time where no matter what you try, you can't succeed; then it's called a "WALL". With this cooler, I think you'll reach 4800MHz anyway. Good luck and have fun!
Thanks! Before we begin, I need to manually set the VCore and stop it from Auto Correcting? Also, what is SOC? I honestly don't know what that means either. I can't see any options for LLC in the BIOS. Forget about that, I was looking at the wrong place. 1.25V seems way too low to get this running on an OC setting. I did see a video about a 4.8OC run at 1.44V which feels high lol but I don't understand how he figured out that magic number for himself.
Well your motherboard might not have the same power controls like an ASUS Crosshair v Formula z does as I used to own. Yes, you can change the Core Voltage from AUTO to MANUAL SOC voltage. This is what turns on all the things that run inside your system on chip devices, including the I/O controller and memory controller. Sometimes they call it VCore SoC or SOC. If you don't have an LLC (low loss clock), then we might not be able to use that feature anyway. I want to start with a low voltage for the Vcore setting at first. It may not boot if you do this, but like I said, just go up in steps of 0.01 volts until the system starts working and stays stable. There is no harm done by undervolting, but overvolting can hurt or ruin your CPU and that damage won't come back easily. For a longer life, it shouldn't be above 1.375 volts when you are using it under heavy load.
Okay thanks, I'm going to try that later when I get some free time to read through it all.
You got everything you need, so we are here to help. Overclocking is fun but can be really frustrating if you don't do it right. I also updated my last post. Oh, and that magic number would have been for a much bigger AIO dual radiator cooler. It's all about the heat management.
Yes, I found that change and it actually makes sense. Thanks! I'm going to be using this chip for my work next night or tomorrow. I really want to see what else you can do with it.
OK so I managed to make a stable OC of 4.4 with a VCore of 1.35 during a stress test, but the CPU temperature hit 21 degrees Celsius at TJMax. That is actually way better than 49 degrees. I couldn't get it to stay stable at 4.6 using 1.4 volts, AIDA64 even said there was a hardware problem. Also, it ran hot. The temperature went up about twelve degrees from the TJMax limit. Do you think that makes sense?
AIDA64 is almost useless when checking if a CPU gets too hot because it won't run at full power (TDP) and mostly just shows you that your temps are very low, which isn't always the best sign of trouble. I heard this from Computronix, who wrote Intel's official temperature guide and has been testing CPUs for years. He told me what he learned many times before: here is a list of 5 utilities that actually work well with steady loads, ranked by how hard they push the CPU: (1) Prime95 Small FFTs v26.6 - a smaller version of the main test (2) HeavyLoad - stress tests the CPU (3) FurMark - burns down the CPU to see if it heats up too fast (4) Intel Processor Diagnostic Tool - runs a load on the CPU (5) AIDA64 Tools - System Stability Test - also stresses the CPU. There is even another small version of Prime95 called OCCT, which uses about 97% of the same power as the main test. This info comes directly from the Intel guide and works just as well for AMD CPUs too. I strongly suggest you change your thermal tests now using either Prime95 Small FFTs or OCCT, both with all AVX options turned off to get a better picture of how hot your CPU really gets.
No offense taken on Darkbreeze, though I disagree. Saying it's useless is a bit too strong IMO, and that's exactly what it is. The P95 test is really harsh; those who push destructive MAX algorithms should just do it themselves. It's like slamming your car's gas pedal down while the engine idles in neutral and leaving it there for hours. No one wants to do that, right? And some people leave the algorithm running overnight unattended, then wonder why their CPU is slow afterward. If a worker fails the torture test without telling you why, they lose out. I've actually used this tool and passed the P95 test only to find my computer crashed just five minutes later while gaming. AIDA64 is probably a tried-and-true test that's less aggressive than this one. From there you can check how hot things get quickly. Aida64 also lets you stress test your RAM and GPU too. It's one of many tools in the arsenal for stress testing, but I think the best and ultimate test IMO is Realbench, which was made by ROG pro Overclockers. If you can successfully run that, then you know you're stable. I've heard about Computronics from Swaziland; it's a private company with its own opinions. Even if you come back and argue against me later, let the OP decide for now. @jay.archard "Tj Max" (Temperature Junction Maximum) is Intel's Thermal Specification that defines how high the Core temperature gets before it reduces speed to protect itself from heat damage. I don't know what AMD recommends, but for longevity I like to keep temps below 80C under load. You should realize that under most normal conditions you will never need to run a stress test like this. Try reducing your core voltage instead; each step up causes the temperature to rise exponentially fast. If you want more analysis, just post some pictures there are likely other things you can do too, but stability is better than trying to gain those few hundred extra megahertz.
