| c0rnelius | The mem on mine idles at 130 running Ubuntu Hirsute. I would imagine it would be less on Devuan. | 00:00 |
|---|---|---|
| Vall | Ubuntu Hirsute: too hairy for me ;-) | 00:00 |
| c0rnelius | I use it to compile stuff | 00:01 |
| c0rnelius | Debian and Devuan don't provide all the tools I need. | 00:01 |
| c0rnelius | I'm not a Ubuntu fan. I would never run it beyond that. | 00:01 |
| Vall | after the change above: used decremented to 68MB... still a lot more thana the RaspiOS at ~48MB | 00:02 |
| c0rnelius | arm64 vs armhf? | 00:02 |
| c0rnelius | zramswap is also installed. could disable it... Not sure it would be eating ur mem though. | 00:03 |
| Vall | c0rnelius: I totally understand. I have an HP ZBook 17 G4 whose model-specific hardware (hard keys, etc) was totally recognized and perfectly configured by Ubuntu. Devuan didn't... so I ended up using Ubuntu on it to this day | 00:04 |
| Vall | arm64 vs armhf -> it could be. I thought they were synonimous? | 00:04 |
| c0rnelius | arm64 runs heavier | 00:04 |
| Vall | yeah, all pointers 64-bits etc, I presume | 00:05 |
| Vall | anyway, never mind. It's my old self trying to save every possible bit of RAM (my first 'computer' had just 1KB of RAM) | 00:08 |
| c0rnelius | I have three boards I use for compiling: RK3399, AML-S922X and the BCM2711. Unfortunately Ubuntu is the only Debian based distro for arm that provides all the versions of GCC and what not I need, so I'm just stuck with it for now. | 00:08 |
| Vall | 20MB plus or minus, in a 8GB (8192MB!) machine, is a drop of water in a very large bucket | 00:09 |
| c0rnelius | Yeah. I wouldn't be worrying about that small diff on the 8GB models. | 00:09 |
| c0rnelius | Its not changing anyway. | 00:09 |
| c0rnelius | anyway/anything* | 00:09 |
| Vall | One question: have you folks installed heat sinks on your RPI4Bs? | 00:10 |
| c0rnelius | all of them | 00:10 |
| c0rnelius | and fans when I need too | 00:10 |
| Vall | yeah, I have a fan too. And a heat-sink set very similar to this one: https://i.ebayimg.com/images/g/dekAAOSwvbZdeNin/s-l1600.jpg | 00:11 |
| c0rnelius | Looks like how mine is setup | 00:11 |
| Vall | (only mine is black for less fluffery and more heat dissipation) | 00:12 |
| c0rnelius | I like the green ones :) | 00:12 |
| c0rnelius | But I think mine has blackones too | 00:12 |
| * Vall looks oddly at c0rnelius | 00:12 | |
| Vall | ;-) | 00:12 |
| c0rnelius | It matches the board :) | 00:13 |
| Vall | LOL | 00:13 |
| c0rnelius | but yeah mine are black, I just looked. | 00:13 |
| Vall | I tjhink I will paint my board black just so it matches ;-) | 00:13 |
| Vall | *think | 00:13 |
| c0rnelius | I have a big blue one on my rock64. looks pretty gay :D | 00:13 |
| Vall | Anyway, my question is: should the smallest one really be put on top of the ethernet controller? Or is it best used on top of the VRM? | 00:14 |
| c0rnelius | I have blue one on my Le Potato as well. | 00:14 |
| c0rnelius | The picture is accurate | 00:15 |
| c0rnelius | In truth you could put whatever size you want there really. Its just those people trying to be thrifty and making it look aesthetically pleasing to the eye. | 00:17 |
| c0rnelius | A little bigger or smaller isn't changing the game up all that much, especially with active cooling. | 00:17 |
| c0rnelius | Be smarter for them next time to move everything but the wifi junk to the under side of the board and just provide one big heatsink. | 00:19 |
| c0rnelius | Much like Amlogic and Rockchip vendors do now. | 00:19 |
| Vall | My question is actually not whether to swap the heatsinks around, but rather where to put just the smallest one (the other 3 are pretty much needed at the processor, the RAM and the USB controller) | 00:20 |
| c0rnelius | that lil top left corner one by the eth port correct? | 00:21 |
| Vall | you mean the top *right* one, correct? That's the ethernet controller. I understand is used just for the wired port, and I'm not sure whether it heats up enough to justify the heatsink. | 00:23 |
| Vall | The VRM on the other hand, seems to heat up A LOT: https://www.raspberrypi.org/app/uploads/2019/11/pi4-latest-load.png | 00:24 |
| Vall | (it's the little guy near the bottom left corner) | 00:24 |
| Vall | I was thinking of placing my smallest heatsink on top of the VRM instead of the ethernet controller. | 00:25 |
| Vall | But perhaps the VRM is heat-tolerant and the ethernet controller isn't, so... | 00:25 |
| Vall | c0rnelius: you put yours on top of the ethernet controller? | 00:28 |
| Vall | s/you put/did you put/ | 00:30 |
