01:24:43 <DHess_US> coppice, the ECC is part of the interface logic so it only corrects errors from the memory array during an access, and does not scrub the array even then. It does not do anything during refresh operations.
01:25:07 <DHess_US> And then the interface itself is protected by CRC and not ECC.
01:26:24 <DHess_US> If you have an ECC DDR5 DIMM, then the channel width is 40 bits instead of 32 with the extra x8 DRAM chip providing ECC for each channel. One DDR5 DIMM has two 32 or 40 bit channels.
01:26:52 <DHess_US> Since the channel width is halved from DDR4, the burst length is doubled so each channel still provides a full line.

04:02:31 <Kuschelpony> Hello watcher
04:03:11 <+electrohead> hey
04:03:38 <watcher> how was your day?
04:04:12 <+electrohead> my day is still going, and it's good, you?
04:04:21 <Kuschelpony> it was ok, beeing a bit in hexctic to organize for tomorrow to meet a distant friend and go out to a street parade
04:04:39 <watcher> also good a normal friday

06:35:01 <DHess_US> Easy cooking and easy clean up.

09:42:30 <coppice> steve30: dunno, but surely there must be some forms of registration to get things like disabled parking permits and mobility grants
10:02:54 <Halcyon> Morning all

10:07:09 <Halcyon> Oh yummy
10:09:27 <T3sl4> the "tomato bruschetta" chips are great just on their own
10:09:33 <DHess_US> arch, 100 microamps is on the high side but yes.
10:09:39 <Halcyon> I feel like nibbles now
10:10:14 * T3sl4 puts steve30 on Halcyon's lap
10:13:12 <arch> DHess_US, it works! i tested it. 100uA works nicely, and the temp sensing is pretty spot on
10:13:43 <arch> ill take a vid of the finished product later. i juuust finished soldering everything on the the PCB
10:14:09 <Halcyon> I see as of the new IOS and MacOS update, Apple will start scanning photos on all iDevices and iCloud for child abuse material in the US.
10:15:02 <arch> i mean, apple already snooped on people's pics in the first place
10:15:11 <arch> oc, they wont tell ya that
10:15:13 <Halcyon> Well true, but this is even more invasive
10:15:20 <DHess_US> arch, the better way is to use two currents with a define ratio and then measure the difference in voltage. No calibration is required.
10:16:27 <arch> DHess_US, i just needed something semi-crude. it's for my CC load project. basically, there are two trip points: at 70C, a fan will turn on (and has 15C hysteresis); at 100C, it sends a shutdown signal
10:17:41 <arch> this is what the PCB looks like. disregard the rightmost side of the PCB with Q1 and Q2; i replaced that crappy CC source with a LM334 bodged in: https://i.imgur.com/u1zpwTV.png
10:17:59 <steve30> Halcyon, there were quite a lot of stereotypically gay people lurking around the gay village earlier.
10:18:04 <DHess_US> That is sort of how I have done it in the past.
10:18:50 * T3sl4 zaps arch
10:18:54 <Halcyon> Hahaha did you have fun Steve?
10:19:23 <coppice> a gay village sounds like a town without a long term future
10:19:40 <steve30> In the short time I was wandering around I must have counted at least 3 drag queens.
10:19:58 <coppice> in a sustainability crisis, if you wish
10:20:01 <Halcyon> Sounds a lot like Sydney's Surry Hills, particularly Oxford Street
10:20:30 <T3sl4> coppice: maybe they depend on immigration like the, uh, shakers wasn't it?
10:20:32 <DHess_US> arch, I just used an operational amplifier to make a 0 to 12 volt output over like 10C to drive the fan. The only adjustment was for the diode's offset voltage.
10:20:34 <coppice> drag queens? How many seconds for their standing quarter?
10:22:23 <coppice> T3sl4: are you talking about the migrating quakers? The movers and shakers?
10:22:34 <T3sl4> money makers?
10:23:39 * Halcyon jiggles T3sl4's money maker
10:24:54 <T3sl4> nuh uh, ya gotta swipe the card first
10:25:52 <arch> T3sl4, DHess_US, this is what the actual pcb looks like soldered:https://i.imgur.com/DcdNEsF.jpg
10:26:23 <arch> so tomorrow i just need to solder the mosfet drain, source, gate, and connect the fan (which i already tested with the temp limit), and bam
10:27:49 <arch> then i can finally do some serious load tests. that TO-247 mosfet is rated for high DC current, something like 30V at 4A
10:29:11 <T3sl4> cute

10:34:08 <Halcyon> What you building arch?
10:35:36 <arch> Halcyon, that is a constant current load PCB, completed about 20 mins ago. i took today off from work just to finish it
10:35:42 Quit: coppice ([email protected]) Quit: Konversation terminated!
10:35:51 <arch> and what you see behind is the carcass of a GTX580 GPU
10:36:22 <arch> as you can see, i cut out the GPU and most of the board, but left the connectors and housing. so it looks like a fully functional GPU, but it's not. it's a CC load lol
10:37:53 <arch> and if you're wondering how i soldered that mosfet on the heatsink, i used bismuth solder with a low melting point, 138C. and that heatsink has fins soldered with leaded solder, so ~183C. i have a reflow oven, so i stuck the heatsink inside and let it at 160C temp for 30 mins
10:38:26 <arch> or it's hellish soldering onto such massive...mass
10:38:45 * T3sl4 licks solder on arch's massive ass
10:38:51 <arch> ._.
10:40:07 <arch> welp, time to game. been soldering pretty much the entire day

11:45:31 <DHess_US> I want to plug a SOIC to DIP adapter into a DIP socket.
12:06:53 <T3sl4> how fancy
12:07:08 <T3sl4> looks to be turned pins, mill-max or whatever the cn equivalent is
12:16:11 <DHess_US> I found a mill-max part which will work.
12:16:18 <DHess_US> It wasn't easy.
12:16:38 <DHess_US> Just need a header with smaller pins on one or both sides.
12:16:51 <DHess_US> They aren't cheap.
12:17:42 <T3sl4> there's also flat edge-clip-on kinda pins but i forget who makes em or where
12:17:51 <DHess_US> In the past I just cut up kovar resistor leads and used them.
12:17:56 <T3sl4> there was a thread on this a while ago, don't remember what it was called
12:18:01 <DHess_US> I couldn't find the thread.
12:18:15 <DHess_US> The cop wouldn't eat the donut. Obscure?
12:28:15 <Halcyon> I don't like doughnuts
12:30:45 <DHess_US> You especially wouldn't like this donut. House sprinkled Senokot granules on it.
12:31:22 <T3sl4> might be this one https://www.eevblog.com/forum/projects/best-way-to-put-dil-pins-on-a-small-pcb-to-create-replacement-for-old-parts/25/

12:33:40 <Halcyon> I had to Google that DHess_US
12:33:46 <Halcyon> Yes, that does not sound ideal
12:34:15 * steve30 snuggles up to Halcyon
12:34:20 <Halcyon> Heya Steve :)
12:34:31 <Halcyon> I'm thinking about setting up my new server rack today
12:35:00 <steve30> cool
12:41:12 <DHess_US> Halcyon, if you have never watched House, MD, then I recommend it.
12:42:44 <Tezzers> So, I'm expecting an offer on a new job. I felt like from our conversation, it wasn't even a veiled attempt at "You've got an offer coming, if you really want it". I'm expecting it's a $10k raise, I'm ready to take it. Do I just shoot a two sentence email to my boss saying I've got an offer at $group and I'm taking it and this is my start date? Do I ask them for a counter offer? What's a good compensation to put up with...lackluster
12:42:45 <Tezzers> management? I'm hoping to make a jump from current....$34.30 to $39.70, so what would I ask for above that? That's already what? 13%? So do I ask for what? 20% raise?
12:43:22 <DHess_US> T3sl4, even knowing what to look for, I cannot even find the one I know on Mouser.
12:43:38 <DHess_US> If I did not have the exact part number, then it would be invisible.
12:44:08 <DHess_US> Which makes it look like the one in the photo is exactly the one I found.
12:45:36 <T3sl4> yeah, some things you just have to flip through a catalog to find
12:45:54 <DHess_US> I went through the mil-max selector thing.
12:46:11 <DHess_US> But then I had to decode their part numbers.
12:46:44 <DHess_US> Here they are on Mouser, https://www.mouser.com/Connectors/Headers-Wire-Housings/0350-Series/_/N-ay0loZ1yzvvqx?P=1y9krctZ1z0z63x&FS=True&Ns=Pricing|0
12:47:21 <DHess_US> Probably just buy a 64 pin strip for $8

12:50:13 <T3sl4> sometimes works to look through the "misc" or "special purpose" categories, or filter by removing things you recognize, leaving the things you don't, or that aren't properly categorized
12:50:46 <DHess_US> The problem is that if I remove things which the mil-max pins don't have, it removes the mil-max pins.
12:51:25 <DHess_US> I've already done that several times. At best, I would have to get a list of supplies and work through them like I did for mil-max
13:00:54 <DHess_US> T3sl4, ha, that thread mentioned the 350 series from mil-max which I found.
13:02:34 <DHess_US> T3sl4, that discussion thread reminds me of if you do a Google search for fixing the DM501A, I am the expert.

23:29:58 <watcher> school dvd's that i have for back-ups of my back-up on
