    1723? I wonder the discrepancy. I am undervolting using throttle stop and achieving 2980 but even stock I was getting in the 2400 range.

      That is the problem with the Intel Core i7-9750H cpu and the Acer Nitro 5 laptop combination. When I first got the laptop Cinebench R20 was better than 2200 but I forget the actual values and that is why I never quoted it. After a few months the Acer Nitro 5's Nitro Sense program failed and could not be reinstalled. Later, before I noticed it, when it was too late, the cpu began to fail due to over heating. It dropped to 1850 to 1720 range. After about 17 months (less than one and a half years) of use 3 cores failed. I guess the 3 cores burnt out due to over heating as room temperature in Malaysia is abut 32C (90F) to 35C (95F) so the failure of the Nitro Sense program contributed to the cpu over heating. I now suspect that the i7-9750H, lower power consumption for laptops, has some design flaws and would not shut down when overheating. Today the Cinebench R20 score for the remaining 3 working cores is around 850.

    i got 8k on the multi core r23 cinebench on the same cpu

      My God, that is really great. Was your test done on a laptop with i7-9750H. 'H' is lower power consumption so less heating so slower CPU. Also my Acer Nitro 5 cooling fans had stopped working properly so most likely my CPU was overheating. A few weeks later the CPU burnt up and only 3 cores out of 6 cores work. Now running at half processing power.

      @@dr.peterscroll422 goddam thats messed up, at first I got only 4000 points, but the CPU was locked to 25W due to the thinner laptop design. I found an unlocked bios with the advertised 45W, I then undervolted the CPU, and I also did a tweak (IMON Slope tweak, which makes the CPU thinks it is using less power than it actually is). With all of that I got 8000, on an MSI GF63 Thin. Thinking of applying liquid metal thermal paste for better cooling, but it doesn't get hot while gaming, only on benchmarks so I might not do it. You definetily got one bad laptop... unlucky I guess.

      @@gonzo28_ Thanks for letting me know how you did it. I have tried over clocking on one processor but when I changed the BIOS to allow overclocking the whole motherboard failed and those CH341A programmer cable clips just work for 2 programming operations and then fail. So I bought another 3 cables with clips, to allow me to re-flash the BIOS 6 more times. Then decided against trying to overclock again for some time. Will focus on improving the cooling of the CPU to improve the performance and when I get more confident will try out overclocking again.
