No, you cannot boost the clock ratio on your Gigabyte GA-A520m-DS3H-AC rev.1 motherboard.

So I've been wondering if I can actually overclock my Ryzen 5 5500 using this motherboard. I had someone from discord to help me oc my CPU a bit and all we did was increase my BCLK from 100Mhz to 108Mhz and it's stable. But I don't think that BCLK overclocking increases the speed and performance of my CPU. So, I really want to know if I can increase my CPU's clock ratio with my motherboard. This is my motherboard: https://www.gigabyte.com/Motherboard/A52...-rev-1x#kf
who suggested bclk oc and the best approach? also which ssd model impacts bclk performance? if it runs smoothly without issues, leave it alone—even a small boost is better than risking damage. the only real way to increase bclk further is to raise it more, and yes, a backup Windows installation is wise to prevent accidental corruption. overclocking can cause instability; it might not improve performance much beyond 4600 and could lead to crashes or data loss. similar to RAM overclocking, it’s risky. if you encounter problems, it’s likely due to faulty BIOS or unstable clocks rather than the bclk itself.
You’re suggesting that diving deep into the PCIe bus design isn’t worth it. I’m in agreement—it seems the BIOS code is mostly handled by the developers.
when stability is confirmed it becomes feasible to push overclock limits, especially for regular use or benchmarking. It seems more about meeting benchmarks or achieving good performance in Windows/Post for frequency testing. For instance, with a VDimm 2.3v using VTT settings like 1.6/1.52v and PCIe 100, the results are decent but not exceptional. The real jump comes with VDimm 2.34-2.4v and PCIe 115/120, where the numbers are slightly higher. Generally, PCIe 1.6 and 1.52v buses tend to cap around 105 MHz, while PCIe 1156 usually stays near 105 AFK. I’ve noticed 103 MHz works best with a weak P7P55D, reaching around 200 MHz clock (giga is king for RAM OC and BCLK +4 sticks). Most of the time BIOS crashes occur, possibly due to unstable clocks. I’ve seen reports of similar issues on a Giga Z68M board where setting BCLK caused it to refuse recovery even after shorts. It seems some newer boards might have unique quirks depending on BIOS versions, but it’s definitely worth checking current options.
Someone from the PC help hub on Discord advised me to boost my CPU using BCLK overclocking. I adjusted the BIOS settings, raising the BCLK frequency from 100MHz to 108MHz. I also installed two storage devices—a Kingston 2.5TB SSD and a WDC 3.5TB HDD—and kept them at the same frequency. It’s been stable for about two weeks. He recommended stress testing with Prime95 for five hours, and it performed well without crashing. When we tried 109MHz, the system became unstable and crashed.
Check the BIOS settings for activation. Regarding the clock speeds, you can revert BCLK to 100Mhz and let Boost Clock handle the rest.
Right now it's tracking its speed, and turning on the boost could assist.
