Solved! For reference, here's how I undervolted. It seems that it cant draw enough power, but its weird because the MB is built to do just that. My old 4690k was able to overclock to 4. 6M subscribers in the Amd community. 5 p core and 4. 2-5. 7 allcore? Click 3 dots at end of this message) Privated to protest Reddit's upcoming API changes. Using this method, I'd expect full load voltage below 1. 25v, I didn't try any lower voltage settings yet though. Apparently you and u/austria_fighter7 above have way different values. Slightly off topic. You can Even do a 5. The sp of my 13900K is only 101 when paired with the ROG Z790-E, and it can run at -0. Help Undervolting 13900k + Understanding 4x DDR5. But if the rumored Raptor Lake refresh in late 2023 includes a revised 13900K, the 13900KS might be a short lived product. 38V. Hey, I am in the process of over clocking the 13700k. Disable IA CEP in the same menu. If this is the case, you will need to downclock the memory frequency Those temps seem to be fine. 1v. This was running 5 p-cores at 6000MHz and 3 at 5900MHz. 13900k on ASUS STRIX Z790-E with ddr5 7800. I can't set my own voltage to anything under 1. 7 all core? 13900k voltage for 5. Initially, I tried following this guide, but it seems that they're using a slightly older motherboard with a slightly different BIOS so I don't have the CPU Core/Cache Voltage dropdown. Ive read a quite popular 13900k guide where the writer specifically said high power output Intel 13900K undervolt is increasing temp instead of decreasing. 8, It says that it has speed 3000Mhz. ya bios reported voltage vs vrout under load even with load line 6 drops down alot for 5. Oct 25, 2022 · The same applies to the K chips, 13700k uses chips that couldn't hit 13900k at the same stock voltage, 13600k uses chips tthat couldn't reach 13700k speeds, and they fuse off the missing cores, hopefully the worst ones in the case of the 13600k, so 13900k is already highly binned and won't have much headroom for undervolting. 5 at higher than needed voltages but you get your 5. Default voltage is at 1. For example I've got Gskill Trident Z 6400Mhz RAM, 13900k and Z790 Maximus Extreme. 25V. Skill 6600MHZ 34-40-40-105 1. Used to idle at 29/30C. 01, and tried to load up. 8 build 3). 35Vto 1. With that being said these chips come maxed out right out of the box I've been forced Intel stock power limits and my voltages are still hitting 1. 652v, and I'm wondering if this is normal/expected with stock settings. 3v for the 13900K from anyone, hence why I'm going to get a 13900KS this time. 50°C is to much for 10W with a bigger cooler. The 7200mhz ram is the same price as 4000mhz cl14 DDR4 ram here in my country (400€) so that's the reason why I'm The bin is almost exclusively for CPU core clocks per voltage and core count. 03 and work your way there. Both AMD and Intel chips behave this way, it allows The only things I've done are overclocking the E-Cores by 200mhz (4. SubVettel. Defect 13900K? Core Voltage Offset. F28 (12/14/2023) Kingston 16384 MB (DDR4-2400) - XMP 2. Iirc, adaptive voltage doesn't let you exceed 1. 0 - P/N: KHX3000C15/16GX. 13900k - Unstable unless i give more Voltage to the CPU. I'm unsure if the voltage is a problem or expected but it seems Recommended cooler for an i9-13900k. The only functional difference from 13900K to 13900KS or 13950HX to 13980HX is clocks/voltage. 5GHz boost clock with reasonable temps when The 13900k is really hard to cool. And you're done. With the 10900k I was using an OC with a fair amount of vdroop which kept the temps pretty contained, but with the 13900k I use a simple offset. This is what causes performance loss when undervolting. It's the better-binned chip with what should be higher-quality silicon. 7 GHz lie between 40-50C. The thing is I already bought the 3090 for a price that's considered cheap here in my country. 20. The two other cores will be running 5. The one with E has very weird problem. if you have stock settings (MCE off and intel Adaptive boost off) then it should start out at 5. 200v. 34-1. if you have intel adaptive boost on which is usually default on motherboards it should be 5. 050v Next, go to Settings tab > IO Ports Above 4G Decoding > Enabled Above 4G MMIO BIOS assignment > Enabled Re-Size BAR Support > Enabled Go to Save&Ext, and save and exit. I have run cinebench r23 and I am getting a score of 31434 pts and the system is passing stress tests. 28v on a 13900KF. 98 LLC4 at stock y-cruncher N64/HNT/VST stable on a Strix Z690-A. 4 Ghz consumes 1. SkillYourself. The 12900k and 13900k will only be using a fraction of their full core potential, and around pull 80w-100w depending on the game. So buying a new gfx card atm is not on my mind. So you still have some wiggle room there too. With the custom cooling I was able to overclock and get 42876 with the max P-core temps never exceeded 90C. 13900K - CPU Voltage & Freq Changes Dynamically But The System Is Not Stable. Unless you have an excessively well-binned 13900K (F) capable of benching Cinebench R23 at 6 GHz P-cores, a new 13900KS will beat it all the time. I changed the frequency to 7200 and it has been working fine so far without any crashes. Once the sustained current draw surpasses 300A you will start to degrade these chips. 409v max, 1. I have a ROG Strix z790-e mobo with an i9 13900k. 5GHz) and the CPU undervolted by ~0. for places where it matters. 5% performance. gk ql go ty hq nn ns ia eb ck
