Maybe its just compressed heat killing the hardware inside your small case. RTX 3080 dumping 340W of heat!

My exhaust fan with Noctua NF-A14 ippc3000 running at 2000rpm. Feels like hair dryer with my 5900X + RTX 3080.

Yeah that is what i'm considering, an ITX build, i have never build that before.

i thought this only bring the idle to LOW and still able to get high boost as well? no?

Just to update.. seems after upgrade to latest bios for MSI x570 tomahawk WiFi ; I don't get random BSOD

so all these while it's not cpu issue.. most ppl complaint whea error and rma the CPU... But most likely it is because driver issue on AGESA

even though much expensive than retail ; at least its not cut-throat price like gfx card
but if you willing to pay rm200 premium.. maybe can also ask local sellers

Already fixed since AGESA 1201 Patch A.

Those complaining still not fixed need to check their devices instead.

Yesterday I just backed up 10TB worth of movies to a new drive, went without a hitch. Held speed at 150+MB/s constant, which is much better than before where it would fluctuate from 30 to 100MB/s.

I connect plenty USB device and never face any ding dong issue, include external HDD, the copying in and out data is working perfectly fine. I had try in any type of USB up to USB-C.

It could be weary cables or ports. One of my USB 3.0 enclosure works fine after changing it. I bought powered 7 ports TP-link USB 3.0 hub and no more issue. Some of the free cables provided are crap quality as well.

The problem is w/ GPU right now... Even with reasonable Ryzen 5000x pricing... The lack of GPU is killing Ryzen sales altogether...

the greatest thing about pc building is that one can upgrade parts one by one down the road. the current situation kills this.

Will wait and see how low the price at Taobao is going to get, looks like stocks are back to normal in US and China.

Yeah, scalper seller still wanna try their luck as if the CPU is still highly sought after.
$299 at BestBuy
Here's one and another one Taobao store which you can buy without bundle.

Any first hand experiences with B450 ITX boards? Building a SFF rig mostly for Davinci Resolve, and on a tight budget (since it's not meant for me). I currently have a Gigabyte B550 Aorus Pro ITX, but I'm wondering if selling that and going for a B450 board can save money without running into a host of issues in the process. CPU that'll be paired with it is a 3700X.

may i know how to check whether the pcie is running with x16 or x8?

Sounds like the M2 lanes are pulled from PCIE x16 lanes for the GPU, which is weird since Ryzen is designed with 16 lanes for conventional PCIE cards and 4 for NVME.

I've ruled out the Asrock for crappy VRM + heatsink, as the B450 board looks like their B350 one just with a chipset change. Not sure about the Gigabyte or Asus ones though.

Yup this B550 would work great even with a 5950X, I'd reckon. Was wondering if trading down for a B450 board is worth saving a few hundred bucks, since this is a budget build. Guess I'll stick to it.

This works so well!
Previously my 5800x rise to 60C, drawing 23W during light browsing session (Youtube/Facebook) with balanced power plan,
what annoy me the most is the constant fan noise!    
I don't even want switch to stock power save mode because it will stutter even on light browsing session.
After the power plan installed, it only rise to 50C and draw 6W during browsing, more importantly, the fan is practically inaudible  
Thanks, AMD should come with this as stock power plan

no strange at all, architecture specific optimisation is needed for each generation of processors to make full use of the cpu capability.
developer can just use the compiler preset to fine tuning, but inside has a lot of things like enabling and disabling specific parameters. each generation of cpu has different cpu errata that are required developers to read and disable some stuff to avoid the program behave strangely after enabling optimization

yes, depend how much of the optimization you wish to enable, you can just enable i686 and it will run fine from i686 until the latest Rocket Lake and Zen 3, but you wont be able to make a full use of your cpu.
normal application can just use generic optimization aka Pentium 4 or i686, but for some program optimization is needed, trust me dude, like video encoder, operating system.
i've been compiling stuff since x264/ffdshow era until now, i compile gentoo linux lol

compiler optimization still no match for hand tuned optimization (assembly code), without it the program will run 10 times slower.

AMD and Intel doesn't really hide anything, both always publish their cpu optimization, as well as errata guide in PDF.
one of the example https://developer.amd.com/resources/develop...guides-manuals/
Both have developer portal for a reason.

Most program will run fine and is transparent to end user, but internally they detect all the stuff in your PC and enable/disable stuff to make full use of your cpu.
