Hi, I bought a ryzen 5600T processor, when I run cinebench r23 or geekbench, I get lower scores than normal. When I check the frequencies working in multithread, they are lower than normal, around 3.8 ghz, when they should be around 4.2-4.5 ghz.
processor: ryzen 5600T
motherboard: asrock A520M-HDV latest stable bios 3.50
ram: 32gb 3200mhz
os: windows 11
power supply: 650w 80 plus.

latest chipset drivers

Ensure your power plan is set to High Performance or AMD Ryzen Balanced:

• Go to Control Panel > Power Options.
• Select High Performance or AMD Ryzen Balanced (if available).
• Check that the minimum processor state is set to 100%.

done, but no changes.

Appears to be reaching the PPT package power limit of 76W.

Have you tried the single core Cinebench test and is it hitting 4.5GHz in that?

Temps look fine, you could try increasing the PPT limit or set Curve Optimizer to a negative value, but the PBO section in BIOS may be locked since it's an A520 board?

Plus it only has 4+2 phase power and no heatsinks.

If I can reach 4.5ghz in single core, even when playing, it reaches 4.5ghz and reaches 87 degrees of temperature. But when I do a multi-core bench it is the problem. The bios does not seem to have a ppt option to configure.

A single core under load uses much less power than an all-core load. Cinebench Multi-core utilizes every core with 100% load, the overall processor package power is hitting the PPT limit and it's not able to maintain max frequency across all cores. This is completely normal stock behavior and just how Precision Boost works, there's nothing wrong with your processor.

The PPT limit is found in the AMD Overclocking section of the BIOS, also known as PBO or Precision Boost Overdrive. You have to change PBO from Auto to Manual to have the option to increase the PPT. However many A520 chipset motherboards do not offer overclocking features, and may not be available in your BIOS. Even if it was available, increasing the power to the processor may not be a good idea on your motherboard as the power circuitry is very minimal (4+2 phase) and has no heatsinks for cooling.

The other way to go rather than increase the power limit, would be to decrease the power to frequency curve using Curve Optimizer in order to stay under the 76W PPT. You can set CO to as low as -30. However, the CO option is also found under AMD Overclocking or PBO section of the BIOS, which again may not be available to you.

It seems that what you are describing is the problem. And no, there is no AMD overclock option in the BIOS. I wonder if by buying an ASUS A520M K motherboard that has 2 processor connectors I will be able to get the most out of the micro. Thanks for your answers.

Section 4.4 of the A520M-HDV manual details the Advanced section of BIOS but the AMD Overclocking section is missing.

This is a restriction of the A520 chipset. In order to get overclocking features you need a B550 or X570 motherboard. (or previous B450, X470, etc.)
