Intel Elder Lake’s non-Okay collection processors are typically not one of the best for overclocking. These CPUs are locked, that means customers preferring to overclock usually gravitate towards Okay-series processors, such because the high-end Intel Core i9-12900K.

Despite all odds, the Der8auer managed to overclock two midrange non-Okay Intel Elder Lake processors, giving them clock speeds in extra of 5GHz.
Der8auer particulars the method in a video on his YouTube channel and talks in regards to the processor. The two CPUs they overclocked after which benchmarked are the Core i5-12400 and Core i5-12600, each of that are a part of the midrange Elder Lake lineup. These are each locked CPUs, so overclocking isn’t inconceivable, however it’s not as simple as it’s on Okay-series processors.
The capability to overclock a non-Okay twelfth technology Intel CPU will depend on a number of components, such because the mannequin of the motherboard – not all boards permit the Der8auer overclocking of that sort. The CPU can also be going to eat extra energy when overclocked, and overclocking an Elder Lake CPU is, usually, troublesome because of the hybrid core structure.
The YouTuber discovered that Core i5-12400 and Core i5-12600 processors could be boosted by manually altering the bus velocity within the BIOS. This will increase the goal CPU frequency, however the possibility, known as “BCLK OC”, isn’t accessible on all motherboards.

The video additionally reveals all the overclocking course of, and it appears surprisingly easy for a locked CPU. On accessible motherboards, customers merely must unlock the BCLK OC possibility within the BIOS. However, there simply isn’t a lot to it, and in case you’re involved in giving it a shot, watch the total video above.
Der8auer discovered that it was potential to overclock non-Okay Intel processors on the Asus Z690 motherboard, however the B660 motherboard didn’t have such a function. Through his testing, the YouTuber managed to substantiate that overclocking to non-Okay CPUs is accessible on Asus Z690 Apex and Asus Z690 Hero boards operating model 0811 of the BIOS. He dismissed the Asus ROG Strix Z690-I for not having BCLK overclocking accessible. Through his testing, he got here to the conclusion that solely high-end Z690 motherboards with an exterior clock generator can help BCLK overclocking.
Once overclocked the processor will want extra voltage. In the Der8auer’s exams, energy consumption rose to 138W (up from a base 65W) and a few cores started to warmth up, with temperatures reaching 96 levels Celsius. However, it comes with huge efficiency positive factors, which the YouTuber examined within the Cinebench R20 multicore benchmark.
The clock velocity of each the CPUs elevated considerably. The Core i5-12400 has a base clock velocity of two.5GHz and goes as much as 4.4GHz in turbo mode, however when overclocked, it jumps to five.2GHz. Offering excessive efficiency at a low energy requirement, the processor appeared promising from the get-go, so it’s good to see it performing even higher beneath stress. Surprisingly, the Der8auer was unable to hit the identical frequency on the marginally higher Core i5-12600—it solely managed to overclock that processor to five.1GHz.
The additional energy consumption and excessive temperatures had been all for nothing. In the Cinebench R20 check, the Intel Core i5-12400 CPU achieved a 33% efficiency improve in comparison with its non-overclocked state, whereas the Core i5-12600 achieved a 16% improve. In the Battlefield 2042 check, when performed at 1080p on excessive settings, it truly put the Core i5-12400 above the Core i9-12900K, which is without doubt one of the greatest gaming CPUs on the market. Of course, these outcomes will differ relying on the game.
The BCLK OC looks as if a good way to overclock a feature-locked Intel Elder Lake CPU, but when Der8auer’s assumptions are true, it may be a bit counterproductive. Considering that solely high-end motherboards help BCLK, customers must spend some huge cash on an costly board simply to purchase an affordable CPU. In this example, it could be simpler to simply purchase a higher-end unlocked processor. However, if cheaper motherboards help this function, it can open up overclocking and better efficiency for customers on a decrease price range.
