9700k overclock
9700k overclock
Hello, just finished assembling my first gaming PC and was exploring overclocking. I tried a 5.0 overclock attempt. After reading the specifications, I wondered if running at 1.30 volts would be safe long-term. My build includes a Corsair H115i AIO, an ASUS Z390 motherboard, four intake fans and three exhaust fans (including the radiator). Also, I’m concerned about crashes—based on my tests, I expect it to fail, and I anticipate the CMOS clearing during reset from Windows 10. Any experienced advice would be greatly appreciated, thank you for sharing your expertise!
We possess a guide that addresses this subject. It's located at the top of the CPUs Forum, under a "Sticky" section, making it easy to find. Review the entire guide, but focus on Section 11 - Thermal Test Basics. The Intel Temperature Guide is available here: https://forums. It's advisable not to use Prime95 with AVX unless necessary. The latest Prime95 version (29.8) lets you easily turn off AVX options by clicking the corresponding boxes.
Heh, windows 10 wouldn't be removed easily. All resetting the cmos just drains power from a tiny ram chip that holds the bios settings. It essentially restores the bios to factory defaults without the computer needing to be on. Regarding 1.3 volts, many cpus operate at this voltage. I don't see any problems as long as temperatures stay normal.
don't jump to 1.3 at 5Ghz. begin with 1.270 and 4.6ghz, gradually increasing until you locate the optimal setting. I understand that users on 5GHz all cores with 1.270 voltage work well.
As mentioned, reaching up to 5ghz is ideal. However, if you're aiming for that 5Ghz boost, you can begin at 1.3v, perform stress tests, and determine whether adjustments in voltage are necessary. Generally, a range of 4.8-4.9ghz works best for stable overclocking.
Agreed. 5000Mhz is a convenient figure that might be achievable or stable, though it could also be hit reliably at lower voltages with fewer issues.
I've noticed my i9-9900k performs best around a steady 4797Mhz with a ring bus at 4587Mhz at 1.23-1.25v (varies with load). I might remove the BCLK OC to let certain cores run at 5000Mhz for better scores on some boards, but the higher ring bus actually improves results on others, making it not always advantageous overall.
For this chip, pushing to 5000Mhz on a few cores needs much higher voltage. I'm using an H80i v2, but I can't run Prime95, small FFT, or AVX2 for extended periods due to excessive heat – it causes throttling. All other benches, including those without AVX2 or Prime95, are functioning normally.
So I chose the 1.270 at 5ghz from the beginning. Great advice. Just checking if I really had a lucky day with this setup. I followed overclock settings shared by others, except for the lower voltage. Temperatures reached 88F at the highest. Ran Cinebench for half an hour then played for about an hour and everything was fine. Just thought maybe I missed something. Thanks again!
Ok so i tried prime 95 that must be rough!made it about 15 seconds and blue screen.any thoughts on where to start looking into my issue?pc works for what i need it for which is gaming but i find this a fascinating thing.also am i hurting my pc with this?thanks in advance!
We possess a guide that addresses this subject. It’s located at the top of the CPUs Forum, making it easily noticeable. Go through the entire guide, but focus on Section 11 – Thermal Test Basics: Intel Temperature Guide - https://forums. Running any Prime95 version with AVX is not recommended. The current Prime95 release is 29.8, which lets you easily turn off all AVX options by clicking the corresponding boxes. Prime95 v29.8 - https://www.mersenne.org/download/ Select the boxes for AVX2 and AVX to disable those features. Only run Small FFTs; about 10 minutes should suffice for a reliable thermal baseline. The guide notes: "Prime95 v29.8 Small FFT's with all AVX selections turned off are best for evaluating thermal performance, as they match Intel’s specifications for a consistent workload with stable core temperatures. No other program can replicate Intel’s thermal testing exactly." Regarding AVX: Advanced Vector Extension (AVX) instructions were added with second-generation CPUs, followed by AVX2 in fourth-generation models and AVX512 in later high-end desktops like certain X-Series, Extreme, i9, and i7 chips. Using Prime95 with AVX enabled creates an excessively demanding workload—up to 130%, which can harm stability and overburden the CPU. While second and third generations are somewhat less impacted, fourth through ninth generation CPUs may see core temperatures exceeding 20°C higher. Many motherboards in the sixth through ninth generation offer “offset” or downclocking options in BIOS to address AVX issues. You might need a minimum of -3 (300 MHz) to keep core temps at 85°C or lower. Since fourth and fifth generations lack AVX offsets, you can set separate BIOS profiles for AVX and non-AVX software. Most real-world AVX-intensive applications (such as rendering or transcoding) and recent games should not surpass Prime95’s workload without AVX support. According to Intel’s datasheets, TDP and thermal specs are verified “without AVX.” In Prime95 versions from 27.7 to 29.4, you can disable AVX by adding CpuSupportsAVX=0 in the local.txt file found in the Prime95 directory after the first run. However, since core temperatures remain unchanged at 29.8 without AVX, it’s simpler to stick with the standard version. You can also choose 26.6, which lacks AVX support. Processors from the first generation, second, Pentium, and Celeron do not support AVX instructions, so they’re unaffected.
