Thank ya gents.
I figured the memory controller gains alone would be worth it to move to a newer Zen
TIL that the b450 boards can still run the latest 5000 ryzens...
It's always been like that with AMD, older chipsets usually cop a gen or 2 newer with a BIOS update.
My brothers x370 can't run the 5000 series unfortunately.
That is first gen chipset though and we're on 4th gen CPUs
they just locked out the gen 4 pcie action
There was some internet blowup as initially AMD wanted to lockout the mobos completely, eventually succumbing to the pressure of a million raging nerds. There were some funky bioses that allowed the verboten features, but AMD quickly stomped on the heads of the mobo makers putting an end to those shananigans
edit - little know fact, the pressure of one million raging internet nerds (1 GRiN) is equal to 17.38 SpaceX rocket launchs
Anyone else's 5900x a spicy boy? mines under a 3 x 120mm fans AIO and its getting up to 90c. have tried re-seting but same temps
Nope. On a 360 aio and temps barely go over 80.
Mines the coolest CPU i've had in a while. I don't think i can get it to go past mid or high 70's either? I'd hit thermal limits (90*c) on my previous CPU consistently so the CPU reduced it's boost clocks to maintain that as max temp.
yeah, happy to say my 5950X seems to run in the mid to high 70's at full load (cinebench, etc) with a 280mm AIO, but then I'm not pushing it hard. Just jacked the PBO power limits up a bit (~160W, etc).
Coolest running Ryzen chip I have used is the 4650g.
Ran Y-cuncher all tests for 90 mins
4.3Ghz @ 1.356v and didn't reach 57C if HWinfo is accurate. Probably because amps pretty low.
5950 gets hot when you speed it up .
How anyone can OC this an an AIO is beyond me
We’re not really smashing it though like you guys would be.
Also because the die is in the centre of the chip.
On aio blocks the microfins are central and do not cover the ccd’s. When overclocking it’s easy to saturate the cold plate which then isn’t being effectively cooled by the water internally. I’ve had better luck with decent air coolers with upgraded fans, as the heat pipes offer proper coverage. Both the ice giant and dark rock pro 4 have served me better than water on Zen2/3 ever did.
Those mounting kits that adjust the mounting point to align the centre of the aio cold plate with the ryzen ccds would probably do well on an overclocked 5950X also.
Heh, yeah, I'll bet they do get hot
This is my work PC, so yeah, a slight bump up in the power limits (160W max) does me nicely.
both my 5800x and 5950x are watercooled, with 3080 and 2080Ti in the loops respectively.
Both run anywhere from 35-45 dgrees in desktop, and anywhere from 55-60 in games. (my RTX cards sit around 35-36 in games and 28-30 idle) hardly warmup
The Zen's do run a little warm, but no issues.
doing something like Blender or Cinebench sees temps clock right up into the late 70's early 80s depending on ambient.
Neither of my chips are overclocked, with the only clocking done on the mems
5800x - 2x8GB royals 4266c19 @ 4000 15-16-16 IF 1:1
5950x - 2x16GB royals 4000c18 @ 3800 16-17-17 IF 1:1
i did get the 5950x booting at 2000 IF, however very very unstable.
yet to try my 2x8gb sticks in it, see if 2x8 will run 2000IF vs 2x16, but my 5800x has run 2000IF since day one. runs 2133mhz IF as well, but 4000 15-16-16 > 4266 19-19-19
when i get around too will put the 2x16gb royals in the 5800x and see if 2x16 will do 2000 IF as well. higher the IF i run also the slightly warmer the CPU runs idle and load.
BOTH rigs cooled by 1x280mm and 1x240mm Rads in the ITX caselabs mercury s3
Have you tried faster mem speeds with different divider for the IF instead of 1:1?
Wonder if running 4266/4400 at less than 1:1 would actually get better performance vs 3600/3800 at 1:1.
Doubt it, I tried 4100 and the score was lower than 3200 with 1:1
