Futro S550 BIOS/DSDT unlock or mod

[antonioni]

Hi!

I have a problem. Please help!

I have a think client: Fujitsu Futro s550 with Turion TL-60 proc.

Bios: https://support.ts.fujitsu.com/IndexDown...hu&OpenTab=

(S550 --> BIOS)

In windows with Rmclock is everything fine with these settings:

800Mhz 0.8V
1200Mhz 0.9V
1400Mhz 0.925V

I use it on windows at 1400Mhz. It's enough for me and my power adapter.

This processor I used these settings with another computer:

1600Mhz 1.075V
2000Mhz 1.125V

And italian guys do the best:
https://www.hwupgrade.it/forum/archive/i...07749.html

In Ubuntu Server 18.04.06 LTS (and other versions too) with kernel 4.15.0-175-generic x86_64 in boot I give these message:

No compatible ACPI _PSS object found
and CPU error.

CPU stuck in 800Mhz:

powernow-k8: No compatible ACPI _PSS object found.

Original DSDT (and modded - see later): https://www.mediafire.com/file/lf6m41qfp...t.zip/file

Ok, no problem, I use these:

https://wej.k.vu/projects/howto_cnq_athlon_64_x2/

https://blog.michael.kuron-germany.de/20...compiling/

and I create my own DSDT (MODDED) and boot with. Then I give this:

[    4.582850] powernow_k8: invalid freq entries 800000 kHz vs. 2000000 kHz
[    4.582855] powernow_k8: invalid freq entries 800000 kHz vs. 1600000 kHz

[    4.582948] powernow_k8: Found 1 AMD Turion™ 64 X2 Mobile Technology TL-60 (2 cpu cores) (version 2.20.00)

Ok, no problem, I use these:

With PHC-K8 I give this:

[  26.249985] phc_k8: Unknown symbol cpufreq_frequency_table_cpuinfo (err 0)

PHCTool:

I tried the kernel upgrade too.

What else should I do?

Maybe my custom DSDT is wrong.

Here, the PSS package calculator for AMD K8 Processors is lost.

But...no success...

In Ubuntu Server with kodi 1200-1400Mhz is enough for the CPU to play my videos and addons correctly. But stuck in 800Mhz.

Please help BIOS unlock/mod or DSDT mod or any solution!

Thanks in advance!

Please help BIOS unlock/mod or DSDT mod or any solution!

There are no settings in your BIOS, even locked ones, that would be useful in solving the issue of low CPU freq.

It's obviously that the stock BIOS for your mainboard misses _PSS object. You modded the DSDT, and I want to know how you calculated these or those values. Did you have any logic for this? I just noticed that some of them are different compared to PSS package calculator output from https://wej.k.vu/. It might not seem to work, but this is just because browsers in the latest updates block inline execution of scripts and style sheets.
So I saved the article as an offline page to prevent blocking, added more options of frequency&voltage and uploaded it to a cloud file-hosting. The only thing the calculator does not calculate is the value for expected power consumption. But this is not very important. Please check your modded DSDT using it because I see clear difference when calculating the same values as you.

Hi!

I'm very happy with your reply. Thanks!

The logic is... https://www.stderr.nl/Blog/Hardware/S270/Undervolting.html

"From the PowerNow specs we learn that every CPU state has a fid and vid, for Frequency ID and Voltage ID respectively. The frequency is calculated as 800 + fid * 100 (in MHz). The voltage is calculated as 1550 - vid * 25 (in mV)."

(This is mine: TL-60)

and https://github.com/cablespaghetti/phc-k8

" To convert between frequency and fid for K8 based processors, this formula can be used:
frequency = 800MHz + (100MHz * fid)
fid = (frequency/100MHz) - 8

To convert between voltage and vid for K8 based processors, you will need to know what type of processor you have.
For desktop K8 based processors, to calculate the voltage it is most likely you will need to use:
millivolts = 1550 - 25*vid

For mobile K8 based processors this formula seems to be the right one instead:
millivolts = 1450 - 25*vid

E.g.:
AMD X2 processor:
vid = 16 => voltage = 1550 - 25 * 16 = 1150mV
Vid = 24 => voltage = 1550 - 25 * 24 =  950mV
Turion 64 processor:
vid =  4 => voltage = 1450 - 25 *  4 = 1350mV
Vid = 22 => voltage = 1450 - 25 * 22 =  900mV"

So the Turion 64 is a little bit different than X2.

I don't know why but your offline version of calculator doesn't work for me either.

My current PSS settings in DSDT are:

Package (0x06)
                {
                    0x07D0,  //2000 MHz
                    0xFCBC,
                    0x64,
                    0x07,
                    0xE0202C80,  //1100mV
                    0x020C
                },
                Package (0x06)
                {
                    0x0640,  //1600Mhz
                    0x55F0,
                    0x64,
                    0x07,
                    0xE0202E40,  //925mV
                    0x0288
                },
                Package (0x06)
                {
                    0x0320,  //800Mhz  --
                    0x1EDC,
                    0x64,
                    0x07,
                    0xE0202E80,  //900mV  -->"This works."
                    0x0580

Could you write the offline calculator values for 800, 1000, 1200, 1400, 1600, 2000 Mhz?

800Mhz 0.8V
1200Mhz 0.9V
1400Mhz 0.925V
1600Mhz 1.075V
2000Mhz 1.125V

I'd like to try it.

Thanks in advance.

So the Turion 64 is a little bit different than X2.

Hm, didnt know they use different formulas. Interesting information. Thank you.

0xE0202E80, //900mV -->"This works."

Yes, I checked your DSDT files...
fid 0x0 (800 MHz)

Could you write the offline calculator values for 800, 1000, 1200, 1400, 1600, 2000 Mhz?

Code:

{
   0x0320,
   0xFCBC,        // 64700 mW
   0x64,
   0x07,
   0xE0202F80, // 800 MHz, 800 mV
   0x0780
},
{
   0x04B0,
   0xFCBC,
   0x64,
   0x07,
   0xE0202E84, // 1200 MHz, 900 mV
   0x0684
},
{
   0x0578,
   0xFCBC,
   0x64,
   0x07,
   0xE0202E46, // 1400 MHz, 925 mV
   0x0646
},
{
   0x0640,
   0xFCBC,
   0x64,
   0x07,
   0xE0202CC8, // 1600 MHz, 1075 mV
   0x04C8
},
{
   0x07D0,
   0xFCBC,
   0x64,
   0x07,
   0xE0202C4C, // 2000 MHz, 1125 mV
   0x044C
},

I used Chrome to dowload the page contents. Maybe this matters?

Thanks!

For now black screen on boot... I'll try again this weekend.
Here jasmineaura also wrote a calculator:
