Will this create a clear change?
I considered the setup and thought about whether boosting the clock speed would make a big difference. Running it at 3.3 with turbo might not be the best choice, but adjusting BCLK to 3.9 could help all cores run faster without turbo. A 0.6ghz increase could be noticeable.
Yes, all cores operating at 3.9GHz would outperform the specified frequencies.
Compare: 3900 MHz with 1 core, 3800 MHz with 2 cores, 3700 MHz with 3 cores, 3600 MHz with 4 cores.
The difference becomes clear only when performance is critical.
Does your board support bclk OC'ing?
You'll not notice the difference. Games are not static benchmarks. Games fps bounces all over the place, watch any video, you'll see by just how much. That counter will also average the fps for a single number, but chances are if it's over the refresh of your monitor, you will not see it anyways. If it's under refresh, you can't physically tell the difference between 50 and 55fps. Your brain doesn't work that small. You'd need a considerably larger range to compare to.
It's @ 8% difference in ability, or in a game at stock 100fps, you'd get 108fps, which you wouldn't see, and if the game stock was 50fps, you'd get 54fps, which you can't see.
It's not enough OC to make a difference in 98% of games, many of which weight cores more heavily than fps, and the rest really don't use cpu speeds over @ 3.4GHz to much advantage.
Not to say you shouldn't try it, but just don't be mad if the results aren't what you were hoping for.
BCLK stands for Buss Clock, a transmission clock multiplier. In earlier CPUs, it influenced performance across RAM, GPU, PCIe, and USB, causing significant issues after reaching 105.7 and leading to instability in various parts. It also caused CPU temperatures to rise artificially. With the introduction of Haswell, efforts were made to separate BCLK from external components, though results remain uncertain. At 118.5, achieving stability requires a lot of BCLK, often paired with extreme overclocking and LN2 for record speeds. Without proper overclocking, the BIOS can't adapt to power needs. If BCLK optimization succeeded, Intel might upgrade all CPUs accordingly, and manufacturers would likely adopt it as the standard instead of offering free OC software that pushes BCLK up to 103.x, followed by stage 2 at 105.x.
Adjust your RAM speed while maintaining relaxed timing to increase the base clock. Tomorrow I intend to boost a 2.2GHz i5-6400T to 4.4GHz for full overclocking. Stay updated.
bclk OCing typically shows only small improvements. In games I’m unsure this will be obvious, but in other tasks and tests it might matter. Also bclk is quite sensitive—adjusting many components like ram, cache, or pcie can cause instability unrelated to the cpu. Overall, it’s not something to rely on unless you’re very close to a specific target.
The base clock overclocking sets the difference between the pros and the rest. I achieved more than 50% improvement during my most recent attempt. The discussion is located a few pages back, from last month.
