14900K / Z790 AORUS ELITE AX ICE – requires performance advice
Hello! I recently upgraded my whole system yesterday to 14900k/z790 Aorus Elite Ax ice/32gb Tridentz 6400mhz. I replaced my old 10900k/z490 VisionG DDR4 setup. I have no prior experience with the new ECCores and PCores, and the BIOS offers an overwhelming number of settings. I’ve been quietly dealing with 13/14 generation instability for a year, so I decided to switch to this powerful CPU. It’s running the latest BIOS, everything is default, and only XMP is enabled. My temperatures during render/cinebench are around 75°C on the Artic Liquid Freezer III 360 AIO. No throttling detected. My maximum power draw is at 253W under full load, but I’m unsure about VCore behavior or safe operating ranges. I’d appreciate some tips to boost performance—what BIOS changes, clock speeds, voltages, or extra tweaks would help? Also, keeping hyperthreading on for heavy gaming and medium to heavy rendering is important. Thanks a lot! No need for explanations, just quick advice.
Are you operating below 100c during maximum demand? This refers to peak stock configurations. I strongly advise against making adjustments, particularly raising voltages—this often leads to failure. You might consider a slight reduction, but always test it first. Sometimes a functional but subpar unit appears, causing performance to drop when it shouldn't. An undervolt that improves temperature and reduces power use will likely extend the chip's lifespan across more cores within its 253w limit.
It's currently operating at full clock speed within the power limits. Many users lower the voltage to allow more headroom, but I don't suggest going beyond what you're comfortable with. The recent BIOS update improved chip performance by slowing them down compared to the original launch clocks from the boards. Recreating that setting could cause issues, so it's best to stick with the current configuration unless you're certain. The "fix" implemented isn't completely reliable, so keeping things as they are is safer.
Bad suggestion. First, the design is only two years old; second, it generates a lot of heat; third, it draws a significant amount of power; fourth, upgrades aren’t possible. I’m curious about the cost you paid. On Amazon, the prices look reasonable, particularly for the 13900K model which seems even more attractive. If the costs are low, it might be worthwhile, though the 285K version isn’t great and can sometimes perform worse. Exceeding 1.5 volts could be risky, and values around 1.4V should be safe. I suggest adding an IA VR limit in the UEFI to cap voltage if it rises too high—though this should work with the latest microcode updates. Intel claims degradation issues are resolved now. Consider undervolting for better stability. For tasks needing heavy multi-threading, raising power limits might help, but it could damage thermal performance. Ideally, direct die cooling would be ideal.
I received a free platform upgrade and upgraded everything to its latest version. That’s why I won’t accept the information you gave me, just for optimization purposes. My 10900K was overheating more than 14900K.
Hello everyone, 2 days ago I launched my new platform. It runs at 14900k/z790 aorus elite AX Ice with GSKILL DDR5 6400mhz. Before setting up the CPU, I updated my new motherboard to the latest BIOS that fixes issues from 13th/14th gen. Everything is working perfectly! Coming from an OC of 10900k to 5.3ghz, I’m eager to fine-tune my new CPU for both gaming and rendering. Since I have no prior experience with these chips, I’d appreciate some guidance. Also, does it make sense to keep all cores capped at 5.7ghz permanently? I suspect I need to turn off Turbo Boost during testing. I’ve attached screenshots of my idle performance before and during Cinebench (clocks temps in volts). Please let me know if there’s anything else I should adjust! Thank you for your time! The first three screens show under-load performance in Cinebench R23, while the rest are completely idle. CBR23 Multy score: 37828.
OCing my 13600k was pretty straight forward. 1. Enable XMP 2. Set Intel Extreme Profile 3. Set 'All Core' Multiplier on both P-Core and E-Cores 4. Set VCore Mode (I set mine to Override 1.2v) You might need to tweak yours a little more given you have more cores bit maybe start with 1.2v 5. Set my E-Core and P-Core multipliers (I think for me 1.2v got me 5.4 + 4.4 stable and good temps on a dual loop custom loop) 6. I might have tinkered with an LLC setting but can't remember. As a side note, I found the above setting stable on R23 all day long BUT it crashed while loading Horizon Forbidden West. I think I dialled my P-Core back to 5.3 which worked as I didn't want to go any higher than 1.2v as keen not to run into any degradation issues.
