So I'm at bios 1.13 and I recently discovered that my processor won't go above 3.02 GHz upon performing stress test by CPU-Z. Earlier it used to go upto 3.3GHz . As long as  I remember, I didn't changed anything so just wanted to know if Acer underclocked the processor using bios update or my unit is defected.

    What problem were you having with the machine that you thought v1.13  would fix? Jack E/NJ

    I regularly check for new BIOS in support page and update it at soon as new version comes online. I am also eagerly waiting for linux soft lockup fix. After posting this thread I rolled back to BIOS 1.09 to see if clock goes up but the problem still persisted :/

    Are you 100% sure it went to 3.3GHz even under v1.09? Jack E/NJ

    Not Quite 3.3 but surely upto 3.24Ghz.

    I'm a bit surprised you ever saw anything close to the 3.4GHz max for the 2700u. Typically we see about 10% less. Jack E/NJ

    It's 2500U and it supports a max boost of 3.6Ghz but I got only upto 3.2ghz when I bought my laptop which, as you mentioned is 10% less than labelled speed and now it came down to 3.02 only

    The 2500u's 3.6GHz max is definitely AMD advertising hype for a single core & thread, not under a real-world workload that CPUz is supposed to measure. And even CPUz itself isn't terribly consistent or 100% accurate --- it has +/- deviations in measurements.  So now I'm even more surprised you even saw 3.2 GHz. 3.02 GHz is even above the typical ~2.8 GHz average most folks are seeing with this CPU. Quite frankly, I see nothing wrong with your CPU. However, if you keep trying to fix it with updates, in particular BIOS firmware updates and their well-known risk of bricking or side effects, you may eventually succeed in making it defective.

    for me its 3.3ghz during benchmark but due to cores locked at 1.6ghz on battery it lags badly for me on diff app even it takes lot of times to boot correctly even all startup apps are off.

    Do you have any non-Microsoft antimalware scanners running in the background? Jack E/NJ

    Why not try increasing TDP to 30 to 35W and see if the clocks don't go up?

    Nope. Just windows defender and nothing else.

    Yeah, increasing TDP sure gives a boost of 3.56Ghz but then there's problem of thermal throttling and the boost won't stay for more than few seconds before dropping to 2Ghz base clock in order to cool down. Also, it's not a healthy thing for processor.

    So you're saying that AMD is lying when they boast max clock speed of 3.6Ghz?. Isn't it just fooling customers....

    No. All-core maximum boost clock and single-threaded maximum boost clock are always going to be different. AMD or Intel, until you start overclocking. Advertising the maximum single-threaded clock speed is just naming a specific feature of the processor. The fact that the all-core speed is different is not a trick, it's designed that way. They are obviously going to advertise the higher speed because consumers want to see a bigger number. Once you understand the architecture behind the chip, the advertising becomes easier to understand.

    What are your temps like, and have you considered a re-paste? The last few hundred MHz really tax the proccy, so i keep mine locked to 3.0GHz for gaming sessions. At 30W gaming my APU stays at 60 to 62C in this April month. 35W takes it to 64C. I also keep my laptop elevated from the front just a bit (about 2cm) to ensure proper airflow underneath.

    How you guys are able to adjust TDP?
