[QUOTE=aristofanes;632471]Using my laptop is just a small sideproject. On my main computer I also tried to change my clock speed. 5% OC just gave 1% better throughput and some extra heat. But for the memory (DDR4) I got a strict proportionality, i.e. 10% more speed gave almost 10% throughput.

Thank you for sharing tour experiences, I am rather new in this exciting project.[/QUOTE]

Prime95 prp testing is nearly always limited by memory bandwidth. If the main machine spends most of its time running P95, consider *under*clocking the CPU a bit to save a bunch of power. Slowing the CPU by 10% might save 16-20% power use (because voltage can be reduced too), with only 1-2% loss in work production. It's worth experimenting with such changes for machines that run these projects 24/7.

Indeed. I won't hire anyone who doesn't know how to do this kind of thing.

My review process is somewhat non-nominal.

Try [URL="https://www.techpowerup.com/download/techpowerup-throttlestop/"]Throttlestop[/URL] to change your PL1 power limit with a lower value.
(This reduces your performance for other heavy tasks, like video encoding, as well. So you may disable Throttlestop temporally when running such tasks)
[URL="https://www.intel.com/content/www/us/en/download/17881/intel-extreme-tuning-utility-intel-xtu.html"]Intel XTU[/URL] or [URL="https://www.amd.com/en/technologies/ryzen-master"]Ryzen Master[/URL] should work too. However I personally dislike XTU because it might lose your setting and revert to the default value on its own, about a month after your tweaking. This happened on quite a bunch of people including me.

Are you using a gaming laptop? Do you use it like a desktop computer instead of carrying it around?

If yes consider a [B]cheap[/B] laptop cooling pad from Aliexpress (spending too much money on this won't help).

Even lifting the rear side of your laptop with 2 Coca-cola bottle caps helps a bit since this increases the amount of air entering your machine.

Thanks for your comment.
In my small homeoffice I have a capable computer. I use it for handling still images and to generate some YT-videos and the unused cycles for prime assignments.

My laptop is used for taking notes etc when I am not at home, however during the summer my laptop mainly sits on its shelf.
Primes on my laptop is just a sideproject. I have lowered its clock to 1.7 GHz, and the laptop now ticks along at a low but steady speed around 45 deg C.
