it seems like my pc was running slow so i decided to run a cinebench and compare my score to other 9750H's and it seems i am under performing quite a bit. i am getting different results each time as i fiddle with things, but the current best i have done in R23 is 5935 multicore. when i first was looking into why things felt slow i was getting low 4000's.

so far i have taken my laptop apart and cleaned the fans and heatsinks, ensured the fans are all working, repasted with some thermal pad shit i found on amazon that i saw had a better thermal conductivity than ptm7950 (12.8W/mK vs 8.5), but that didn't help at all. i then realized that stuff wasn't a phase change material like i thought it was and ordered something that specifically says ptm7950. so far the ptm stuff seems to be working better but that is how i got to the R23 5935 score.

i have gone and fiddled with random things according to other threads i've found, so my settings might all be pretty off right now. i reached out to unclewebb on reddit and he pointed me in this direction. i've attached the things he mentioned to post. i'm hoping to get this thing running like new or even better, with the undervolt. the current undervolt i achieved before applying the new ptm7950 stuff.. i'm not sure if i should try to go further now. i just got 12.037 on the 120M TS bench, and 108.305 on the 960M without errors, both of which are the best i've seen since starting this journey to get this laptop working correctly again.

i've seen the limits be different things throughout all the changes i've made. i followed some steps rom other posts and was able to not have pl1 or pl2 but was hitting thermal. eventually i deleted my ini and tried to start fresh again but i'm pretty sure it's all a mess.

edit: i just did a timespy and added the results screenshot as well as a TS log.

I had an i7-9750H and I believe I can help you.

First check the MMIO Lock box in TPL.

Return your Ratios (FIVR) to default as this CPU doesn't support overclocking.

Then, if your undervoltage is really stable (no errors in TSbench is a great start), lower the core voltage to -190mV.

Maintain -115mV in cache.

Take a long test on TSbench and check if any errors appear.

If everything is ok, run a test on Cinebench and compare the results.

Without changing the Windows priority, my i7 was doing about 8000 to 8100 on the CBR23.

Time Spy's CPU score was 7100 to 7200.

This is after several BIOS updates with security fixes from Intel.

Initially (2020) my i7 could do +8300 (CBR23)...

It was completely stable with -125mV / -210mV in cache/core on Windows balanced power plan (Speedshift 84) and -135mV / -225mV on high performance plan ( Speedshift 0).
