We've got the same CPU (a nice little workhorse for a very gentle price I'd say)! I assembled the PC myself (hadn't done that in like 15 years for I had a shop do it for me but decided that this time, to not get too rusty, I'd do it myself) and put a Noctua NH-U12S cooler/fan on it, in a "Be Quiet!" tower (with a Be Quiet! PSU). So I like quiet fans. Anyway I'm running Linux and put on all (but one) workspaces (or "virtual desktops"), the CPU governor in "powersave" mode, where apparently the CPU doesn't got above 3 Ghz and doesn't go above 45 C. Then on my "dev" workspace, the one where I need the performances, I set the CPU governor to "ondemand" and a single core can boost up to 5.51 Ghz (as reported by Linux) or all cores at once up to 4.9 to 5.1 Ghz with the temp reaching 95 C (which I think is how these 7000 series are meant to operate: they'll boost but then shall lower a clock a bit to not go above 95 C). I configured my WM to automatically change the CPU governor depending on which workspace I'm on. I'll never here the CPU cooler's fan when in "powersave" / "max 3.0 Ghz / max 45 C" mode. When the governor is in "ondemand" mode, I'll hear the fan indeed once I start compiling stuff. I may, sadly, remove the RAM EXPO setting (seen that I bough DDR5-6000) while waiting for an ASUS BIOS / firmware upgrade for my Prime B650-Plus mobo. It's not cool to run DDR5-6000 at 4800 but I'd rather not fry the CPU/mobo.

I have the same cooler! No expo issues on gigabyte ds3h. Why haven't you undervolted the cpu with all your interest for noise?

Honestly I'm not too sure how to do that. I never bother overclocking/underclocking. I like everything stock. I thought running DDR5-6000 from the QVL list in EXPO mode was also something really normal to do.

    I've never heard of QVL before and this comes in great because I want to build a PC. I've been a laptop user for many years.

I considering a build with 13600k, and I am seriously just considering going with DDR5-4800. It's a tad cheaper than the DDR-5600 I was initially going to go with. I honestly do not think I would be able to tell the difference in day-to-day usage between DDR5-4800, DDR5-5200, DDR5-5600, and perhaps higher than that. With that being said, I acknowledge that I am just making an assumption. Have you noticed any difference outside of benchmarks? I am not looking to go higher in speeds because I have seen videos (e.g. from Buildzoid) talking about how awful the 13th gen memory controller is, so I figured I am not really looking to gamble my time and money on max performance RAM.
- epolanski 3y ago
  I have not measured the impact outside benchs and yes you are probably fine with 4800s, but I use my pc for work and I would avoid slower ram when as a dev all my IDEs and processes do nothing but R/W from memory.
  - hirvi74 3y ago
    As a dev myself, do you think the difference between DDR4 and DDR5 is actually noticeable? That was mainly my justification for going DDR5 -- not gaming -- but I could step down to DDR4 if the the difference is insignificant.

  Every time I'm setting up a new PC, I check the prices on RAM and then check the benchmarks for actual usage, and I always seem to find that buying faster RAM is not a good use of the budget, especially because I need a PC with a lot of RAM. Currently running a 12900k with DDR4 RAM. When I checked the benchmarks, DDR4 ended up being about 3% slower than the fastest DDR5 which was more than double the price, which for 64Gb was a significant price increase. Even less difference for gaming, something like 1%. https://www.techpowerup.com/review/intel-core-i9-12900k-alder-lake-ddr4-vs-ddr5/7.html https://www.techpowerup.com/review/intel-core-i9-12900k-alde... I'm sure it's a similar story for the different speeds of DDR5. The price premium isn't worth the tiny increase in speed. I guess people see the big numbers like 4800 vs 5600 and assume that means it's that much faster, 17%, when in reality it's something like 1-2%. Faster RAM has always been a ripoff, and like you said you're risking stability issues. https://www.guru3d.com/articles_pages/ddr5_core_i9_13900k_ddr5_7200_mhz_memory_scaling_review,16.html https://www.guru3d.com/articles_pages/ddr5_core_i9_13900k_dd...

Wow, that's a pretty cool idea I've never considered. Switching CPU governor based on the virtual desktop.

Even simpler idea is just to disable turbo for "quiet" mode.

>...how these 7000 series are meant to operate: they'll boost but then shall lower a clock a bit to not go above 95 C). Bah, I have clearly been running my fans too hard. Using stock configuration, my 65W CPU idles in the low 40Cs with slightly audible fan noise. If I disable/super-slow RPM until 45/50 C, presumably that would be completely fine, and give me a near silent build. Obvious in retrospect.

I know that KDE has the concept of activities, which is an even different concept than virtual desktop and would be interesting in that regard.

Sorry about the OT but I would love to hear your experience with your build since I'm going to build a very similar one: AMD Ryzen 7k with DDR5 and the exact same mobo. My mail is in my profile
