overclocking expert @Build Zoid 1 recently on twitter shared a post He talks about his frustration with AMD’s overclocking capabilities on the RX 7000 series. Apparently, AMD has locked down the operation of the power play table on their new GPUs, preventing enthusiasts from customizing power and frequency curves outside the official specs.
So it looks like AMD hates overclocking so much that they decided to lock the RX 7000’s power play table. I think his RTX 2080 will probably be replaced by another his Nvidia GPU.December 23, 2022
The Power Play Table provides an alternative way to change the GPU clock speed, power and voltage behavior via the Windows Registry instead of a BIOS mod or BIOS swap. This is a safer way to run your GPU outside the official limits as it prevents possible risks when flashing the BIOS.
If you want to know why AMD’s overclocking feature set in Adrenalin software isn’t enough, here you go. Adjusting the power play table, or manipulating the BIOS, has several advantages. One is that the user can bypass the firmware-related limitations of his GPU hardware and push the hardware to the max. Another is optimizing the voltage/frequency curve for higher efficiency. Either way, it allows enthusiasts and enthusiasts to tweak their GPU’s behavior in very detailed ways that are not accessible through regular overclocking software.
Unfortunately, we don’t know exactly why AMD shut down power play operations on their Radeon RX 7000 GPUs. Especially if the previous generation card had this feature. But an AMD engineer on Reddit might give you a clue as to what’s going on.according to Reddit post Discussing RX 7000 power consumption issues, user Falk_csgo asked about driver limitations related to GPU overclocking. AMD Engineer AMD_PoolShark28 replied, “Architecturally he RDNA3 has made some changes to how he manipulates PPTables…”.
At the very least, we know that since the RX 6000 series, the way users edit and access the RX 7000 power play table has changed. A bit of a guess, and this is probably why the power play table locked on the RX 7000 series.
This means that the power play table lockout is temporary and AMD will regain access eventually. But we really don’t know.
