I built a new i9-9900k PC for CbB

Recommended Posts

Damn this makes my new laptop seem weak. Got a newer i5 8th gen cpu 32gb ram ddr4 an SSD C drive with a 2tb hybrid hdd drive. How do you set the cpu to fixed, is that in the task manager or via cakewalk preferences?

If you've got an off-the-shelf laptop, it may not expose the BIOS parameters necessary to stop all performance throttling.

The cooling in a laptop (in such a tight space) is not ideal for locking a CPU at the highest TurboBoost frequency.

With a tower, you can use over-spec'd cooling (much more significant heat dissipation)

I highly recommend water cooling for the i9-9900k, it is a hot plate with a free room heater inside a thermonuclear reactor. You should plan to see 200 watts of power used by it if you want to run over 5 GHz, so find something that will get that heat out of the case. Once you get it cooled,  I think we are starting to get to the point where all this optimization stuff is becoming moot. 

There are a bewildering array of UEFI BIOS overclock and memory parameters, so you can spend weeks tweaking. My MB BIOS has over 400 parameters according to the saved text profile and I think I know how to tweak,  maybe, 50 of them. The rest are trial and error (or AUTO).

I ended up using an adaptive clock setting, starting at 4.7GHz per core and allowing up to 5.1 GHz per core in the rare times that is needed. Honestly, I think I only see that when I run test benchmarks. My own extensive audio tests and benchmarks make me happy with these settings.

The only constraint I decided upon was a VCore limit of 1.4 volts. I needed a bit more than that to reach 5.2 GHz and it didn't seem worth it.

Thanks for your insights, @Jim Hurley :)

I've gone with a traditional cooler, for now. I opted for a full tower so that I can add a few more fans if need be. In the meantime I will just have to see how it goes.

cheers

I have 11 fans, 3 on a 360 mm radiator.

When I train a neural network using the GPU and CPU, it uses 450 watts - 200 on the CPU 250 on the GPU.

I wrote some stress tests in Reaktor and ran Prime95 overnight, here are some charts to show the power and temperatures.

Don't say you haven't been warned!
