<Mat2ch>
it depends on how much money you actually want to spend.
<Mat2ch>
The price for 4600 MHz memory is double the amount than what you have to pay for 3200 MHz.
<darsie>
So technically all speeds are ok, as in not harmful?
<Mat2ch>
you can always run faster memory at slower speeds.
<Mat2ch>
But it also helps to select a vendor and go to their website and see if they have tested that memory with your processor (or a similar one)
<Mat2ch>
usually the also add the overclocking profiles.
<darsie>
Ok, but that's silly. Just overclocking might damage things.
<Althego>
modern cpus basically overclock themselves if they have t he thermal headroom
<Mat2ch>
The fun fact about AMD cpus is that you usually can overlock the memory and the cpu benefits from it, because the waiting time to access the memory is lower.
<Mat2ch>
Althego: not the memory controller.
<Althego>
and you cant win much with it, unsless you go the liquid nitrogen route
<Althego>
the memory controller too
<Althego>
that is the xmp /expo settings
<Mat2ch>
those are fixed settings you select to run the memory at
<Althego>
and modern amd you basically have to turn it on anyway, so
<Izzy>
new hardware is weird I got better performance by underclocking
<Althego>
you an get slightly better performance by undervolting slighty with the curve optimizer
<Izzy>
gave it more thermal headroom by mildly undervolting and underclocking yeah
<Mat2ch>
Interesting
<darsie>
WTF, there's illuminated RAM ...
<Mat2ch>
for years already!
<Mat2ch>
You can have your case light up like a christmas tree. And worse.
<darsie>
Yeah, I've seen fans etc.
<Althego>
man, are you under a rock
<Althego>
everything high end is rgb
<Althego>
whether you want it or not
<Althego>
i managed to get by with minimal, there is only an xfx light n the video card, not changing colors, and the ram doing rainbow
<Althego>
which is slightly useful, because you can see the fans spinning and even the 4 error leds
<Mat2ch>
you can get everything without RGB, too. But sometimes getting the stuff with RGB is just cheaper
<Izzy>
unironically thinking about getting some RGB LED strips because I'm a BeOS fangirl
<Izzy>
stick em in the front transparent part of the case and use them as a load graph
<Izzy>
already got RGB fans though, because those were the cheapest aliexpress fans that didn't have awful reviews or lifetime rating of "no"

some people went so far and gutted tft displays and put them behind their window. (Have fun trying to get a case without a window these days...)
<sandbox>
oh?
<darsie>
THe one I'm after is plain as fuck. With a dent.
<Izzy>
I'd be worried about them melting because that would put them in front of the GPU

I could get 2x16 GB 5200 MHz for 100 EUR.

my previous one had a window, but it was kind of pointless as that side faced the inside of... well, basically against the wall of a cupboard
<darsie>
Instead of the 2666 MHZ 32 GB

can only dream of having two memory card slots
<sandbox>
my current case has a windowed option so I went with the windowless version of the case

there was a special type of oil I remember

If it's saturated fat it'll solidify. If it's unsaturated it'll polymerize.

There's mineral oil.

Or silicone.

Silicone oil comes in a huge range of visciosities.

it was something else more obscure that I remember a one-off build using

Should still be on your screen. Or did it scroll off on your phone?

Well, the main memory category is cat=ramddr3, including all the DDRx.
<Eddi|zuHause>
Deddly: the reasoning there i disagree with the most is that ";" means a shorter pause, because on reading, because of its rarity, it'd imply a longer pause.
<Mat2ch>
darsie: all of your selections are not just ddr4, that's what I meant
<Mat2ch>
I want to make sure we both see DDR4 only
<darsie>
right, the one wiht 5200MHz has DDR5 and only one DDR4, thx.
<Deddly>
Eddi|zuHause, It's between a comma and a full stop. So it's a longer pause than a comma for sure.
<Eddi|zuHause>
Deddly: yes. but it breaks the reading flow, so it's also a longer stop than a period.
<Deddly>
Eddi|zuHause, Not really. At least, that's not how it is intended.
<Deddly>
Eddi|zuHause, For example: "I like sausages; they taste great with potatoes." It's the sort of place where a lot of people incorrectly use a dash, like –
<Mat2ch>
Looks good. There is a chance that the OC mode does not work or not fully work. I for myself have 3200 MHz, but can't go above 3800, because my system gets unstable. I guess due to heat, I have a fully insulated case
<Mat2ch>
Deddly: geizhals is a price comparison site, so yes :)
<Mat2ch>
I think you have to unselect all else to have it shown
<Deddly>
175 Euro for 16 gig. Heh.
<Eddi|zuHause>
Deddly: then it's a great example of a discrepancy between intended effect and actual effect.

I moved and bought an All New machine with a 5800X3D; good thing I did because the previous one's PSU blew up on friday
<Izzy>
Nearly exactly 10 years old, heh.
<Azander>
wow
<sandbox>
Izzy, did it damage anything else when it blew up?
<Izzy>
Haven't tested to be sure. I think it killed the HBA I was testing, because the server won't boot with it, so that's not a good sign.
<Izzy>
Hopeful the GPU is still okay though, the 580 is middling nowadays but's still plenty useful
<sandbox>
I never even tested my old GPU, I assumed it was probably toast
<Izzy>
If it lives, I'll replace the 980 in my mum's machine with it; it may be no faster, but it will mean I never have to deal with NVIDIA drivers again
<Izzy>
If not, that's a shame, but ... well, I was running it hard. Going out in a blaze of glory is respectable.

shrugs
<Izzy>
Kinda mad, but I guess I'm glad it waited till now to give out.

my game PC needs a better PSU. it can't run two HDDs (plus one SSD) and the GPU at the same time. when a game tries to load assets, the disk shuts down and restarts

<Izzy>
sixty seven amps
<Deddly>
yum
<KrazyKrl>
Then you overclock a CPU and it runs at like 1 volt with 600 amps.
<Eddi|zuHause>
that's like 800W?
nasonfish has joined #KSPOfficial
<Izzy>
yup
<Eddi|zuHause>
what kind of beefy GPU is that?
<Izzy>
I haven't heard of a single GPU using that much. NVIDIA's current peak ones are 350-400W per GPU though
<Eddi|zuHause>
i have like 6 HDDs running and never had problems with my 500W
<Izzy>
Apparently what's going on is everything that uses any significant power (CPU, GPU, etc) has its own power regulation stuff, and is regulating down from the 12V rail
<packbart>
my 2080S is about 250W at full load
<Izzy>
so rather than multiple rails with balanced overall wattage, you get like 20W on the 5V rail and 700W on the 12V rail
<Izzy>
the single 12V rail, that is
<packbart>
it makes sense to put the power regulators close to the chips. they draw power in ugly near-squares
<Izzy>
the 6700XT I've got can use like, 225W, theoretically
<Izzy>
wildly understressed pushing 1200p60 though
<KrazyKrl>
Remember that if you're using high wattage GPUs/CPUs near the PSU's limit, the switching noise can cause substantial transients which may trigger OCP on your PSU.
<packbart>
I heard an anecdotal report from a supercomputer user. his code sadly synchronized in a way that all the cores would switch between idle/full load/idle at more or less precisely the same time
<packbart>
the power supply didn't like switching a few kilowatts in microseconds and gave a loud bang
<packbart>
they use random delays in their code now
<Izzy>
it's funny, I originally got the 750W PSU that popped to run a pair of GTX 690s, which were wildly inefficient monsters. 600W total.
<Izzy>
that 600W was across 4 GPU ICs - meaning each individual GPU used "only" 150W, which is pretty small nowadays
<Izzy>
double that would not be unexpected for a single GPU. wild.
<packbart>
According to Nvidia its DGX B200 chassis with eight B200 GPUs will consume roughly 14.3kW – something that's going to require roughly 60kW of rack power and thermal headroom to handle.
<packbart>
In a liquid-cooled configuration, Nvidia says the chip can output 1,200W of thermal energy when pumping out the full 20 petaFLOPS of FP4.
<Althego>
i heard there is a new future for analog computers, because they can run neural networks with little power and exact precision does not matter for that
<Eddi|zuHause>
dunno, most AI stuf i've seen runs with 8bit integers
<Eddi|zuHause>
but that might be because it's been designed for GPUs
<Althego>
they go as low as they can get, i think there are lower than 8 bits now
<Eddi|zuHause>
yes, but that only makes sense on hardware that benefits from those data types
<packbart>
4-bit floating-point and such
<Althego>
so anyway with that you can go to analog and consume a lot less power
<Eddi|zuHause>
but, can you produce them in quantities high enough to be relevant and cost effective?
<Althego>
shouldnt be too hard
<Althego>
it is basically what 50s or 60s tech
<Eddi|zuHause>
yes, but you don't have 70 years of miniaturization on the production lines
<Althego>
actually we do
<Althego>
bot the analog components stopped scaling a long time ago
<Eddi|zuHause>
and not an established market in the billions of chips
<Althego>
sram stopped scaling about two processes ago
<Althego>
so the only t hing scaling now is logic
<Althego>
and probably n ot for long
<Eddi|zuHause>
i'd file it under "neat idea, but probably not scaling properly"

You insert a used toilet plunger into the MPL in order to generate science points while landed on Moho. You devour the Grey Goo.
<Althego>
must be tasty
<Eddi|zuHause>
depends on WHAT the toilet plunger was used for
<Althego>
and obviously those connectors should be standardized on the psu side too
<Althego>
but that they can change for the same manufacturer in the same type of psu, that is stupid
<Althego>
and then they dont even tell you, send you a replacement, and oops you burnt everything
<Eddi|zuHause>
don't these kinds of connectors have codings to avoid mis-plugging?
<sandbox>
I remember hearing about when my school had a delivery of Apple computers where the PSUs weren't set for UK voltage...
<sandbox>
I'm glad I wasn't the work experience kid that day
<Eddi|zuHause>
i blew up a thingie which had uncoded connectors when i accidentally offset it by 1 pin
<Eddi|zuHause>
as far as i could tell, it blew out a resistor or something, but nothing essential, so it was someone else's problem to fix
<Althego>
if you have seen a modular psu, they usually use the same type of plugs
<Althego>
but what the exact pinout is, that is random
<Althego>
so certainly you cant plug in its own cable wrong
<Althego>
but you can plug in a similar looking cable
<Althego>
which will be then wrong
<Eddi|zuHause>
doesn't that defeat the point of the modularity?
<Eddi|zuHause>
because you can't easily extend it later, you have to buy all cables in one go
<Althego>
the point is, you can remove the cables you dont need
<Althego>
for example i dont have any sata device anymore
<Althego>
but need 2 out of 3 pcie power cables for the video card
<Althego>
other might have a raid array with multiple sata power plugs, and no pcie power
<Eddi|zuHause>
sure, but imagine i add that SATA raid a year later...
<Althego>
and it is compeltely fine
<Althego>
because you add it to the psu with its own cables
<Eddi|zuHause>
but i can't buy new cables to go with the array, i have to dig out the original PSU box
<Althego>
but in this case the hidden evil was, the manufacturer changed the pinout in a later version of the same psu. the guy got a replacement psu, and by the instructions of evga he did not send the cables, because they do not send the cables back, just a new psu. so he gu a new psu with incompatible pinout
<Althego>
and plugged in the old cables to the new psu
<Althego>
clearly an oversight by the manufacturer
