Adjust settings to lower core temperature and boost performance.
Adjust settings to lower core temperature and boost performance.
My setup is clear now. I’m using Lian Li 011 Dynamic EVO, Galahad 360 AIO with a 7x 120mm fan upgrade and MSI z790 Carbon WiFi motherboard. I have an Intel i9-13900k with two 32GB G.Skill Trident Z5 RGB chips at 6400 MT/S CL32 (XMP). My PSU draws about 350 watts, the CPU runs at around 1.4V, and four of my eight cores reach 100°C.
At first, I set up my BIOS with "Water Cooling/AIO" preferences and left everything else default. When I ran Cinebench R23, the results were extremely poor. The power draw was high, temperatures soared, and some cores stayed near 100°C. I switched to MSI Bios settings, choosing "Tower Air Cooling" which capped power at 288W. That helped a bit but still left me with two cores consistently at 100°C in Cinebench.
Then I experimented with negative offset values, starting with Adaptive+Offset and adjusting down to -0.09v. The performance was inconsistent—sometimes stable, sometimes overheating. Eventually, I switched back to AUTO mode with a negative offset (-) and managed to hit around 276W. Temperatures stayed between 90-95°C across all cores.
I tried changing the "Lite Load" setting from 9 to 4, which gave the best Cinebench score so far (5.48GHz). But the temps were still high, and I was still struggling with heat management.
Now I’m considering alternatives. I removed the offset mode and returned to AUTO, keeping Tower Air Cooling active. This gave me the highest stable clock speeds (up to 5.4GHz) but at 270W max draw. It’s not ideal, but it works.
My goal is to lower temperatures further—aim for 5.5GHz across all eight cores and keep two cores at 5.6-5.7GHz. I’ve seen others achieving better results with less cooling and even lower temps. I’m happy with stability in stress tests, but performance remains a challenge.
I also question whether those achieving such high clock speeds—especially around 5.8GHz—are completely reliable. Reaching 5.8GHz with Cinebench is manageable, but maintaining that consistency without a specialized loop is nearly unattainable. Given the targets you've established, it seems you'll need to implement a manual overclock. Stock configurations won't provide this, and even then, the thermal demands are somewhat unrealistic. The typical procedure involves configuring the system in Mode 7 for optimal performance, adjusting the voltage via the DigitALL menu, setting core ratios (Pcore, Ecore, ring) around 55:42:45, and running stress tests to monitor temperatures and stability. If the system holds steady with acceptable temps, fine-tune the ratios; otherwise, adjust voltage or core settings accordingly. On average, the cooling limits for a multi-core processor under heavy load like Prime95 are around 56°C, 45°C, and 48°C—though actual performance varies widely between chips.
Thanks for your feedback. Regarding the LLC at mode 7, this is handling things differently than expected. At around 1.4 volts it seems like the system is operating under higher-than-usual conditions. During those tests with Water Cooled and 360 watts on the CPU, I was seeing voltages between 1.4 and 1.5 volts, which is close to what the VCORE reported. It felt like the system was pushing a lot of power, hitting the CPU temps near 95°C or higher. I’m concerned about staying within safe limits, especially with multiple cores under stress. If you can achieve stable performance at 5.6 GHz across all cores for 15 minutes and keep Cinebench scores between 80-90, I’d be happy to hear your thoughts on the auto/adaptive settings. For cooling, sticking with unlimited wattage for water cooling or a balanced approach with case fans should work. As for the Lite Load setting, reverting it back to mode 9 might help if you want more consistent performance. Let me know how it goes!
This adjusts the load line calibration, influencing voltage changes when the CPU operates at full capacity. Higher Vdroop improves regulation and reduces temperatures while maintaining stability. Mode 7 typically results in a 150-200mV drop under full load, matching performance from other MSI boards and delivering strong results. At idle, the voltage should hover near 1.2-1.25V with an LLC set to mode 7. For single-core tasks at around 6GHz, aiming for about 1.4V idle is ideal. Usually, I configure it for a water cooler setup and avoid touching the Lite Load since it doesn’t impact overclocking as described. For auto/adaptive settings, I’d note them but keep them disabled, opting to override them when needed.
I adjusted most of your settings but ended up with extreme temperatures at 1.4 V and LLC at 7. I modified the core voltage to 1.25, switched Load Line Calibration to Mode 4, enabled the BCLK 100MHZ lock, and restored water cooling with unlimited power. I also reverted to manual overclocking. Now I'm stuck at 5.5 GHz across all cores, with the highest temperature reaching 93°C for most cores in the high 80s. This appears to be my strongest result so far. What further actions should I take? Should I manually set PL1 and PL2 to 253 watts or is that not necessary? I just want more headroom to push overclocking a bit higher. 5.5 is decent, but 5.6 would definitely improve things! (laughs)
This setting appears inconsistent with typical behavior. At Mode 4 the voltage should be lower than at Mode 7 (1.175V vs. 1.2V), though not drastically so. Based on my Z690 Unify-X configuration—which seems identical to yours except for the iGPU phase—I expect similar LLC parameters. Mode 7 usually targets around 1.20V at full load, and Cinebench often supports up to 1.47V while staying cool, especially with a 13700K. You might want to switch from VCC Sense to Socket sense for lower readings, as that tends to reduce output voltage. I’d appreciate a screenshot of the current settings you’re adjusting. Power limits only affect performance if you exceed them; setting them lower will drop temps but also cut speed. It’s safer to keep voltages unlocked and fine-tune rather than locking values. For 5.6GHz, raising the multiplier from 55 to 56 should help, provided your cooler can handle it. Most cooling units should support 5.8GHz if your CPU is decent.
Yea, 1.4 and mode 7 give me HIGH voltage still (~1.37-1.41) and it makes the temps hit 100. So, I got greedy 5min ago and went with vcore 1.25 and tried putting the LLC into mode 3, it BSOD'd me. The strange thing was 1.25 Volts in Mode 4 seemed fine? My tempts were still in the 90's but low 90's. It was showing the CPU pulling just 266 watts as well versus the 1.4 in mode 7 which was pulling over 300 still (thus giving me crazy heat). What if I tried 1.3 volts in mode 6? Is it possible me locking the BCLK 100HZ to enabled is causing issues? Note, I also did not set any of the ratios you had mentioned since those are higher values than what I'm pulling right now in auto/default and I am already overheating....
This setup seems unusual. Mode 3 likely performs better than Mode 4. It appears they may have swapped the LLC order, which usually means higher LLC mode on MSI boards results in more Vdroop. It looks like they flipped it so Mode 8 has no Vdroop while Mode 1 has the highest. Would you like me to try a test? Configure the CPU clock at 4GHz for P cores, 3GHz for E cores and Ring, set voltage to 1.25V, then compare readings from Mode 1 and Mode 8. Use HWInfo for accurate voltage checks. Also, clarify how you're adjusting the voltage—BIOS or XTU? And if using MSI Dragon Power, note the bug that resets VCore readings to Level 1 LLC when used.
Im setting everything inside BIOS, I actually do not like relying on software like XTU for tuning or just in general. While I was waiting for your response, I went back in and changed Voltage to 1.35 and left LLC at 7 (with BCLK lock still enabled). I did not get BSOD, and temps and results are better HOWEVER, now cinebench is constantly crashing on me? No idea why, and it's not even sending the log file to it's folder for me to check crash report. However, it will run for 2-3 minutes and during that short time span, things seemed peachy at 1.35 volts with LLC at 7.
