| 08:46 | jnettlet[m]> | Love the design of the new fan I am testing. https://photos.app.goo.gl/scIjJHZf6LMXlfGB3 |
| 08:47 | jnettlet[m]> | but running full out it is just too loud. Will work on that |
| 08:54 | vpeter> | Made from one piece of aluminium block? |
| 09:07 | jnettlet[m]> | yes |
| 09:12 | Ke> | jnettlet[m]: fake!!, I can see, because not all the ATX power connectors are even connected!!! |
| 09:13 | Ke> | I guess it just collects all the 12V into a single line or something? |
| 09:13 | Ke> | how is that heat sink attached to the board? |
| 09:15 | jnettlet[m]> | what is fake? |
| 09:15 | Ke> | never mind that |
| 09:15 | jnettlet[m]> | :) okay |
| 09:16 | jnettlet[m]> | the heatsink is connected with adhesive currently. I will 3d print a mount soonish |
| 09:17 | Ke> | so it would likely fall off, if mounted vertically, I guess |
| 09:17 | Ke> | ? |
| 09:17 | jnettlet[m]> | temps in u-boot are 38, 44, 43 |
| 09:18 | jnettlet[m]> | yeah, until it mounted to the board. |
| 09:18 | jnettlet[m]> | I just received it this AM...need some time |
| 09:18 | Ke> | I guess there is a chance that you will share the mount design? |
| 09:18 | jnettlet[m]> | I also need a better controller for it |
| 09:18 | jnettlet[m]> | of course |
| 09:18 | Ke> | thanks |
| 09:19 | jnettlet[m]> | but I think I will need to get my own 3d printer. I have less and less time to get over to the Makerspace. |
| 09:19 | jnettlet[m]> | the heatsink design fits perfect. gives nice access to all the jumpers and switches. |
| 09:21 | jnettlet[m]> | just getting out my patchset to properly support NVMe for u-boot. |
| 09:33 | jnettlet[m]> | okay that is emailed out. |
| 10:06 | topi`> | jnettlet[m]: do you think you could sort out how to do proper PWM to the fan connector? |
| 10:06 | topi`> | well, to be honest, for me the more important feature would be to control clocks in software (cpufreq) |
| 10:07 | topi`> | allowing the board to comsume less power until needed |
| 10:07 | jnettlet[m]> | All on the list. |
| 10:21 | topi`> | :) |
| 10:21 | topi`> | I could perhaps proceed with my idea of testing a Radeon card on the macchiato. I have pcie16 -> pciex1 adapters |
| 10:22 | topi`> | first need to get tianocore working |
| 10:36 | Artox> | [12:33] <topi`_> I did not build this, it seems the builder was abuild@armada-8040 The deb? |
| 10:36 | Artox> | Its kinda old now |
| 10:39 | Artox> | it is the latest -mxbin branch of Marvell though, so idk |
| 10:41 | topi`> | maybe they've moved development onto another branch? |
| 10:41 | topi`> | or they're just happy with their stuff for now ;) |
| 10:42 | Artox> | they have a -armada branch where they work in, but idk how generic / tested that is |
| 10:42 | Artox> | https://github.com/MarvellEmbeddedProcessors/linux-marvell/tree/linux-4.4.52-armada-17.08 |
| 10:44 | Artox> | it'll be a few days before I try that though |
| 10:59 | jnettlet[m]> | topi`: I just hacked up the pcie connector for my old Quadro card :) |
| 11:02 | jnettlet[m]> | https://photos.app.goo.gl/MhZiVaikYQ85WpIi2 |
| 11:05 | topi`> | ouch |
| 11:05 | topi`> | poor Quadro ;) |
| 11:05 | vpeter> | Very creative :) |
| 11:05 | jnettlet[m]> | there is virtually zero difference between x4 and x8 regarding performance in this class of card. |
| 11:06 | jnettlet[m]> | even now you really only see a 10-20% drop in most GPU benchmarks going from x16 down to x4 |
| 11:06 | jnettlet[m]> | 4K...well that is a bigger difference |
| 11:27 | suihkulokki> | hw hacking :) |
| 11:28 | suihkulokki> | funny how the ebays pcie x16 -> x1 cables are sold as "bitcoin cable" |
| 11:33 | topi`> | :D |
| 11:33 | topi`> | nevermind that mining BTC on GPUs provided economically infeasible years ago |
| 11:37 | topi`> | hmm, mining on multiple Cortex-A72 cores, how would that work out... when are we going to have those 32-core Armadas? ;) |
| 11:46 | topi`> | btw if I want to have another gigabit rj45 on my Macchiato, can I use one of these 10gbps ports for gigabit, or do I need to buy a SPF module for gigabit copper? |
| 11:47 | topi`> | https://www.amazon.com/StarTech-com-Cisco-SFP-GE-T-Compatible-1000Base-T/dp/B007UR0CZE <-- this costs over 60 dollars :( |
| 11:58 | topi`> | hmm, macchiatobin wiki says it is either 10gbps or 1gbps: |
| 11:58 | topi`> | Dual 10GbE (1/2.5/10GbE) via copper or SFP |
| 15:46 | jnettlet[m]> | topi`: order from http://www.fs.com or find them used on ebay. |
| 15:46 | jnettlet[m]> | much cheaper |
| 15:48 | topi`> | do the linux drivers support forcing a 10gbps interface to 1gbps mode? |
| 15:48 | topi`> | I should test this out, but right now only have a 100mbps hub here |
| 16:50 | vpeter> | topi`: You still using hubs? |
| 16:53 | Artox> | these things just don't die |
| 16:59 | vpeter> | I have one to make network sniffing easier. Sometimes can be useful. |
| 17:17 | jnettlet[m]> | topi`: yes with ethtool |
| 17:18 | jnettlet[m]> | Although if you just insert a 1Gbps SFP module it will automatically negotiate down |
| 17:31 | topi`> | Artox: hubs are cheap :) |
| 17:31 | topi`> | actually I don't know if my gigabit D-Link is actually hub or a switch |
| 17:32 | topi`> | "5-Port Gigabit Unmanaged Metal Desktop Switch", yes it is a switch |
| 17:33 | topi`> | but it has too few ports for my office, I need to buy a bigger one |
| 17:39 | Artox> | topi`: if you can buy some, sure |
| 17:39 | Artox> | but switches are cheap too |
| 17:39 | Artox> | if you don't require them able to switch maximum bandwidth (1Gbps duplex / port) |
