is it just me or local retaillers are selling motherboards at 30-50USD markup as well?

MSI Tomahawk B550 at RM800, but newegg sell USD150....
if convert, should be 600+ only

my only concern from online retailer is i dont have CPU to flash bios for 5000 series   
unless can borrow yours?

Built another Ryzen rig:

Spec:
3700X on Wraith Prism
Gigabyte B550I Aorus Pro AX
2x8GB DDR4-3600
HP EX950
FSP 450W PSU
Radeon 6670 (ancient card used only for video output)

Set up the rig, plugged a USB drive with Windows installer to it and turned it on, but no display output is visible. The mobo RGB LEDs light up in orange, and the Wraith Prism appears to use the RGB profile from BIOS, though. No error beep codes when I plug in the speaker piece to the 4-pin header on the motherboard.

Tried the following steps, the PC still doesn't boot:
- removed SSD while leaving the Windows installer USB drive plugged in
- reseated SSD
- reseated RAM
- use only 1 stick of RAM in either slot
- removed all RAM sticks (in this case, this was expected to fail - the motherboard also failed to activate RGB LEDs too)

The CPU, RAM and GPU were tested on other machines and they worked fine. I presume I should RMA the mobo next? What else may I have missed out on testing?

Never thought of swapping RAM sticks! I just plugged the Bolt XR in another rig, it POSTed just fine, assumed it was not a RAM issue and never considered RAM compatibility with the BIOS.

Let me see if the BIOS flashback option works. I presume it functions even without working RAM?

So I finally jumped into SFF, with a NR200P for my new build - my son's PC one day just refused to boot no matter what I throw at it (old FX6300), thinking its not worth salvaging, so I decided to give my 2600 to him, and make a new one for myself. Yes it's nothing high end, some stuff I got at sale + local pc shops

Ryzen 5 5600
Thermalright AXP90-X47 Full copper
Asrock A520M ITX-AC
Silicon Power 8GB x2 DDR4
Superflower Silver Eco 500W
silly R5 240 gpu (temporary..)
in NR200P with 4 Sickleflows
Latest BIOS, chipset drivers
Balanced power plan

So immediately after booting and updating drivers etc.. I noticed the idle is on the bit high side (50C+, 40++ only during cooler nights/morning), and it vey quickly shot up to the 95C limit even with simple CPU-Z bench/stress test. Even running SignalRGB at the background keeps the idle temps at 60C+, hence I've deleted it and will switch to a hardware ARGB controller). Coming from my previous 1200 and 2600 that never even got above 80C on full loads, I am very surprised.

Anything I should take a look, or check, other than the usual cooler re-seat, repaste stuff (of which I read is quite decent for a low profile cooler, almost comparable to the Noctua NH-L9i). PBO, Curve Optimizer stuff that I admit haven't really dabbled before? The 5600 should be .. cooler than my previous chips, being more efficient, no?

Granted I haven't try gaming on it, waiting for my 6600xt to arrive.

Thanks for any feedback in advance, guys.

Because I had to vertically mount my gpu, due to using an ATX PSU, and thus leaving clearance for cpu cooler at 75+mm something. And also out of curiosity, from using tower coolers all these time. This is more like an experiment build with stuff I'm not really familiar with + stuff I have lying around. Yea I don't game much these days, but seeing those temps sure scared me a bit.

Also I read AXP90 reviews are decent, here and there, too. Was thinking perhaps I'd swap the fan to maybe an Arctic 92mm or something..

Sure there's no BIOS setting I can poke around?

Indeed, trying a few things out for testing, but probably changing to a new cooler isn't in the cards, at least for the time being. But even if I swap to a SFX psu and mount the gpu horizontally, it'll be a bigger slab of .. gpu radiating heat blocking the intake fans below. I do plan to swap to a 25mm thick fan with better pressure, and put on the vented panel, all after re-seating the cooler with AM4 stock backplate. But I do recall even removing the side panel all together not doing much, iinm. And I currently have a silly R5 240 on which I believe isn't all that hot, either.

It's just.. I can run my ol 2600 on high performance power plan w/out such a spike in temps, and I only have it on a CM 120mm AIO. And how the temps spike from 50 to 90 in just a few seconds during simple stress test is rather surprising.

Like which RAM? Not available here doesn't mean not available everywhere.

I'm skipping both Zen 4 and Raptor Lake too, will stick with 5900x. Happy with it for now.
