Unique techniques for I9 10900 without K BIOS tricks
Unique techniques for I9 10900 without K BIOS tricks
I faced issues with my i9 10900 non-K and a gigabyte b450m hd setup, experiencing VRM overheating and performance drops. Now I have a z590 Aorus Elite paired with a cx750f power supply. The CPU runs smoothly with default BIOS settings, but running CPU-Z gives a 6700 score compared to 4400 on the older board. I attempted to adjust the power limits, but no significant improvements beyond seeing the CPU draw 110W under full load. Any advice for optimizing the BIOS?
Uncertain about working with a non-K chip. I think there are BCLK adjustments you can make. I've heard about undervolting as well. It's unclear how much control you have over the VCORE in that setup. If possible, you might want to gradually reduce i by 0.050 steps and check for stability after each change. A lower VCORE won't significantly boost performance but could help keep the chip cooler.
Above the power ceiling, that's likely all there is. The multiplier is fixed, and beyond a certain BCLK overclocking it probably can't go any higher. If Turbo Offset is available, you might be able to add +1 or +2 to each core clock (Turbo Boost settings). My 5.1Ghz Allcore 10850k has a 7770 score, and most games would be GPU-limited with reasonable settings—so you won't miss much compared to my CPU in gaming. The key difference between us is how we handle CPU-bound tasks versus GPU-bound ones. As noted earlier, you could lower the voltage for even better performance.
You have the option to undervolt, which helps maintain CPU temperatures below 70°C, providing a +100MHz increase in clock speed (Intel’s Thermal Velocity Boost). If your CPU consistently stays under that threshold across all cores, this won’t significantly boost performance but will lower power usage. The 10900 should support higher power limits exceeding 110W. Have you also adjusted the PL2 timer limit? Also, memory overclocking is now possible even with non-K CPUs, allowing you to test higher clock rates for DDR4 if needed. Intel’s memory controllers typically handle high frequencies, so if your RAM meets the requirements, you can likely push it 10-20% above stock speeds—useful for gaming and tasks like code compilation.
Non-K chips limited by BCLK won’t reach far because Intel built this feature into the chip’s design. To truly optimize performance, you’ll need a K chip, as that’s the standard Intel requires. Some older non-K models have shown they can handle higher BCLK/FSB speeds but need a BIOS tweak—those aren’t easy to find. Only certain sponsors, like HWbot, possess the necessary BIOS files and refuse to share them, likely due to contractual restrictions. So if you’re serious about overclocking, switch to a K chip and stop trying otherwise.
The update came with the new generation chips, but its compatibility with older models depends on the specific hardware.
For Z series boards, performance remains consistent. The key change came with the B560, which introduced a new feature to the B series chipset, and this addition has persisted in later models.
