[Request] Clock Speeds

[PS3-4K-Pro]

Following the overclock patched firmwares and the ongoing xai plugin overclock on the fly, would be a nice addition to show the CPU/RAM and RSX/VRAM clock speeds.

I'm not sure how to retrive such information from kernel. Maybe @aldostools would know

[aldostools]

The clock speed is currently hardcoded in lv1.self It would require to decrypt the hypervisor to obtain that information. It is supposed to be found decrypted in the RSX memory address, but it is unconfirmed.

is RSX memory stored in LV1 or LV2?

I think it's LV1, but I haven't confirmed. Check the following link; https://www.psx-place.com/threads/project-rsx-boost-overclock-your-retail-ps3-rsx-speeds.36801/page-9#post-328447

Aldo I found the GPU clock speed for 4.84 DEX in LV1. I'm also trying to find the CPU clock speed by searching "be.0.ref_clk" in the LV1. It would be nice if you can find these but for CEX so I can add it to the plugin.

// rsx_dev_clock_1 + 0x1C
uint64_t m_GpuNvcSpeedOffsetInLv1 = 0x53E42C; // 4.84 DEX

// rsx_dev_clock_5 + 0x1C
uint64_t m_GpuDisplayClockSpeedOffsetInLv1 = 0x53E46C; // 4.84 DEX

Here is a dump_lv1.zip from 4.88 CEX.

Maybe it can help you to compare and find the offsets that you need.

LV1/LV2 kernel offsets in 4.84 and 4.88 should be very similar.

EDIT: The string "be.0.ref_clk" is found @ 0x3288 and the value +0x24 (@ 0x32AC) is 0x17C841C0 => 399Mhz??

[TheRouletteBoi]

399 doesn't seem correct and nethier do I know the default value. Wikipedia says 3.2 GHz

EDIT: Offsets for 4.88 CEX

// rsx_dev_clock_1 + 0x1C
uint64_t m_GpuNvcSpeedOffsetInLv1 = 0x5383EC; // 4.88 CEX

// rsx_dev_clock_5 + 0x1C
uint64_t m_GpuDisplayClockSpeedOffsetInLv1 = 0x53842C; // 4.88 CEX

[aldostools]

**The most approximate value to 3.2Ghz that I found is near to "be.0.nclk" at 0x3F7C It has the value BE420E00 = 3,192,000,000

[TheRouletteBoi]

Actually if we round up to 400 then mutipliy by 8 to get GHz we get 3200. 400 MHz * 8 = 3.2 GHz

Is this reasonable?

[aldostools]

It sounds forced... but it is a possibility.... I don't have experience with that info.

[TheRouletteBoi]

I don't know if this is correct but I got " * 8 for GHz" from this post. Apparently he overclocked the CPU. https://nitter.net/MinaRalwasser/status/1458862608384155650

[aldostools]

Well there are 8 processors 😄 it makes sense
