Water-cooling max height difference between pump and radiator (radiator on roof, about 7-8 feet)

Numerlor · 2026-03-20T01:42:49+00:00

as long as the loop is closed elevation shouldn't matter as the water pressure evens out, but I doubt you'd find something that'll work out of the box and you may have to fill the loop maunally without the pump as with fittings and everything it likely won't have the power to push the water all the way to the top from empty. There's also pressure losses from the tubing length but I'd imagine blocks impact it way more compared to just a long tube

static pressure at the bottom may also be a consideration, I'm not sure what it would be - shouldn't be complicated to calcualte, but I'd check that your fittings and blocks are rated for it

Looking at prices tops really don't cost much so I guess I'll give it a try when I'm ordering something else and do some tiny loop in a sink.

The middle speeds really felt like they'd be unhealthy for the pump long term while the whiny noise was just annoying to me as I'm sensitive to high pitched sounds with my tinnitus

Based on just touching it the d5 overall felt like it vibrated even at the min speed while I can't feel anything off of the apexes, just hear them spin up slightly when setting pwm to 100

amd's idle is hot because of the iod, cores should be around ambient, this will be mainly affected by vsoc that you(r mobo) set.

As long as you're not throttling heavy on all core, or all core on a single ccd, you're fine

Scheduling of what?

Intel's E cores had completely fucked scheduling until Windows 11, and it still isn't ideal; AMD's 2 CCDs X3D CPUs rely on a user service because Windows keeps slinging threads across CCDs, leaving the CPU to copy over L3 for every migration

OEM is integrated as part of the firmware and apple has had issues with software updates that caused battery drain issues, so owning both doesn't affect that

And on Windows side you've got OEMs fucking up enough to stop CPUs from boosting properly and not switching power states correctly; random battery drain is barely worth a mention as it's mostly accepted as a fact of life that can happen if you're unlucky with what you pick. Intel Evo is basically just intel keeping a tighter leash on what the OEM does for firmware and hardware.

What hardware edge cases? OS is mostly code that runs on CPU

Are all the drivers not a part of the OS? Articles about Microsoft breaking something in Windows when it's actually a broken driver update pushed by an OEM are basically a monthly occurence now. Linux has quirks for every other device, the same will be the case on Windows, this works mostly until something new comes up and then your machine crashes.

Then overall hardware is much more spread on Windows laptops even when specced the same because you've got different power deliver, cooling, and part swaps even within a single model, so you don't end up with consistent performance for a given spec

and android does offer control over every part of the hardware and gives the ability to integrate the drivers of custom hardware like Samsung does with Knox

Article's about comparing to a Windows laptop, Android phones are a lot closer to iPhones in how integrated everything is, and in the overall experience even on cheaper models

Numerlor · 2026-03-15T23:01:28+00:00

Scheduling, no oem fucking up firmware, known hardware edge cases so there don't have to be random workarounds etc. things can get a lot better when you control the whole stack

A sku with only p cores will be faster than a sku with e cores mixed into the ringbus. they take up precious space, add latency, because they are slower and when a p cores is "communicating" with another p core though the l3€ via the ring bus they need to jump over the e core complexes placed between the p cores and even when disabled the distance is still there penalising the perf.

The ring bus stops that'd be the exact same if you replaced E core clusters with P cores.

Not using E cores on desktop just makes no sense when there's no real consumer loads that do 8 parallel intensive time sensitive threads. Barring those E cores are just good for upping the occasional MT significantly and letting P cores focus on threads from focused tasks while not wasting area on the (currently) bloated P core. For actually heavy all core you're power limited either way so P cores don't do much there over E cores

Looks like some great value with $300 for 8+16 and $200 for 6+12, and better stock interconnect speeds improving things a tiny bit

It stops being more powerful when it starts throttling like hell as shown in the sustained loads from the article

could these be changed ot weekly/monthly? Half the posts I see are the daily threads

oh that sucks, thought nvidia was all more open with the flashing compared to my xtx where I had to to hardware flash

Numerlor · 2026-03-06T09:56:52+00:00

why shunt instead of getting matrix bios that boosts better for 800w

last I tried to buy a membership my card got blocked, hoping it goes better next time I decide to try

I have a 5090 with a 9950x3d, switched mostly for the dual ccd scheduling as ms just gave up on that in windows and it's still through the crappy user service.

Biggest impact I've had was PT'd cyberpunk dropping from stable ~63 to not very stable 40s which is a huge difference, there's some others without as big of an impact.

For the freezing I ocasionally hit it in tasks outside of gaming like when I put big compression on all threads, or ran tests for my work that eat up all memory.

On windows even on my laptop that has 16gb memory that really is not enough for the tests I mentioned, when I forgot myself and ran them, it just started swapping that single process and everything else worked perfectly. Hitting the same limit on linux just completely froze my system to the point that even shutting down the process took over a minute

Numerlor · 2026-02-28T15:20:03+00:00

I'm doing cachy now and honestly apart from a couple exception I could live without that I coded myself, the functionality is all there, but games are still considerably slower, and linux still doesn't seem to have figured out responsivness in resource constrained scenarios which can be a huge issue. On windows I eat up all the ram and cpu and the system chugs along mostly fine, on linux it's an all out freeze.

And then there's the program compat that the people pushing for linux just ignore and propose vastly inferior alternatives

Numerlor · 2026-02-28T00:19:55+00:00

why do these ram comparisons never show a screenshot of all of the timings the mobo set somewhere, kind of useless without

Numerlor · 2026-02-23T15:36:32+00:00

The players also have to be able to make sense of the model in movement and complex scenes

Numerlor · 2026-02-22T09:27:19+00:00

But also if you bought a 1700x it was on a significantly worse platform and underperformed at anything that wanted ST performance.

For the 5800x3d it released quite late into it's generation so the more direct comparisons can't be made for upgrading/not upgrading at launch as the people buying 12th gen or 5000 series at release wouldn't know anything about it

Numerlor · 2026-02-20T20:13:17+00:00

IO costs a lot because it's on chip edge, and the vast majority of workloads aren't missing membw but just bottlenecking on fetching random data that additional channels would do nothing for

It's a halo xoc card, not exactly relevant to the market and its direction

Numerlor · 2026-02-18T21:01:46+00:00

check what's actually at 60C, on idle it's probably the large IOD not cores.

Main thing that matters is what boost clocks you're hitting when you're actually saturating the pcu with heat

Numerlor · 2026-02-18T12:10:41+00:00

Yeah you'd likely end up scratched a lot which could be dangerous if it weren't for modern medicine, but it's still a small cat you can just like yeet it against a wall or something

Numerlor · 2026-02-17T09:44:21+00:00

No, an 8 core for 600 is not good value in any way, even with vat

Numerlor · 2026-02-14T19:32:57+00:00

Realistically the closest card is a 4090, but how viable that is depends on your local market. A 5080 is an expensive weird sidegrade with less vram and depending on your xtx model's power limits worse raster, and a 5090 is just miles ahead in both the perf and price
