Laptop overclocking adventures

There "is" way to get around some of those security updates. Don't know if this has been patched already https://github.com/SmokelessCPUv2/SmokelessRuntimeEFIPatcher#lenovo-bios-unlock At the bottom of github-site there is two codeboxes(AMD&Intel). First one of those boxes should have every bit of code you would need to use with Srep+config-file. If I understand how this works->You use Srep with that code->reboot and your bios now have more settings(?). Will it work, I don't know.

I cannot really help more on with patching, as I don't have similar hardware which I could use for testing. I have never really used Srep in anyway. Maybe in future, if I can modify my Fujitsu's bios someway.

I have unlocked bios using this. Problem is it refuses to boot if I change any setting in ram tuning menu.

I am just thinking: If it requires values in hexadecimal format, as the Formbrowser does with memory timings. Example: smallest timing for CAS I could choose was 14h CLK and numbering after 19h was 1Ah (20). So you could try hexadecimal values.

There are apps for this and Windows calculator(view->Programmer) can also convert decimal to hexadecimal, you can also calculate in our head or use table max value is FF.

If I remember correctly: All values which are higher than FF/255->example tRFC goes with precalculated values. When you found value which boots, tuning gets easier. You can always start from FF but those can be too high.

No, if I simply set ram overclock to auto and kerp all settings it wont boot. Others report the same. I have been able to disable power down mode etc, but if I touch anything in ram oc It wont boot :/

As I can't imagine Lenovo's bios interface in my head->Hard to say what kind of menus you have unlocked. It is also possible that access to memory settings is disabled somehow.

I did find Lenovo Legion 5 15ACH6H which should be same or near.
-Extracted bios setup file to 7-zip setup
-Extracted that to bios file(bios.fd)
-Opened with Uefitool and searched for tCL and extracted all three PE32 files to bin-files
-Did run those with IRFExtractor and now there is 3 txt files. One just show language choices

Seems that there is 2 places where timings could be entered. Aodsetup(Lenovo or H20 bios naming) and CBSsetup. I don't know if you have access to both of them. I don't know anything more.

I have only found the cbs-section and enabling ram oc, which is required to do before I start messing with speed/timings causes no boot. I will search for the aodsetup-thing

I have the exact model you found. This is in many ways the perfect notebook: g-sync, mux, good display, 130W 3060, nice design. If I only could tune ram for that 20% extra in certain games it would be perfect!

I did read your laptops extracted CBPsetup and compared it to my laptop. Nothing interesting just couple more values compared to 4000 series Ryzen. My laptop uses CBPsetup for memory settings and etc. Atleast I didn't find anything similar solution like Lenovo. Next I will read what is in aodsetup file.

Also I have never read my laptop's CBPsetup settings as text file format and I did found that there is Fclk and even more settings, but those are not shown in Formbrowser. So I have to enable this somehow someday. Probably enable whole menu in bios.

It would be awesome if you can find a way to make ram oc/tuning work on Lenovo+5000, on 4000 it apparently works fine. Maybe an older bios can get it working?

I got UAFB working, tried activating ram oc, no boot once more :/

Not sure if I've done this right, but this is an ibm t41 with a pentium m 780. Theoretically this should work. I have over clocked the fsb here from 400mhz to 533mhz. Yes I fixed the resistor.
