Secondary PC with a 3700X died. Sent it for warranty claim, was told it was OOS. They gave me options to pick either a 5600X or to top up RM300 for a 5800X.

Should I top up or go down to 6 cores? This setup only has a Wraith Prism for cooling, so not sure if going to 8 is worthwhile without tweaking power usage with Hydra/CO etc.

Yeah makes a lot of sense for me. Guess I'll go 5800X then. I can probably just use Hydra and CO/PPT/EDC/TDC to tweak its power usage.

Haiz, I ran into problem again on my system just under a year.

My PC shut off and restart randomly during normal operation.
The blackout is fast one, just a second before it alive, but it won't boot with Qcode 00 (not used code!!!) and QLED stuck at DRAM, and system not response to power button long press either. Have to kill the AC switch, then it will boot normally.
It will even reboot sometimes in BIOS setup page.

Try swap my RAM, still happen.
PBO disable, not fix.
Even run at optimised default also reboot.

I suspect now is due to either CPU or mobo, with highest suspicious on CPU.

Can you guys suggest a sensible way to further test out whether is CPU or mobo? I'm frustrating now as i just recover from a nightmare failure on my previous system before i switch to AMD platform, and the seemingly HW issue haunt me again.

I just want to avoid buy something new just to isolate the factor, but i won't know exactly the issue if i didn't do so, contradict, arggg

The problem can be consistenty reproduced when doing system memory stress in AIDA64, which lead me to believe is RAM issue, but swap with different pair of RAM didn't solve it. Your point is valid, i'm currently stress it under single channel and let see what's the outcome. My RAM only can run in the current slot if run in pairs, run in another dual slot won't boot due to the design.

As for the PSU, even if it failed, the system should have boot normally when power resume rather than stuck. The thing is, even the long press power button shutdown is not work when it stuck, i have no idea why and i believe this is an important crue as well. The system simply locked unless AC killed.

I think i found the problem already, which hint by the Asus sound card.
The sound card would required external supply from Molex 4 pins and will prompt if is not.

So somehow after the reboot the prompt appear, i'm like impossible because that 4 pin Molex is very tight.
This trigger me potentially is a PSU issue.

So i fire up the stress test again, and monitor the voltage level from both Corsair link and HWinfo64. The Corsair link reported 12V and 5V is extremely stable even under 600W+, what surprise me is the mobo reading in HWinfo64 shown only 11.56V and 4.65V from both rails.
Immediately i open the casing and measure the 4 pin molex at sound card using digital multimeter, the 5V is measured around 1.8V and 12V rail at 11.78V. Once i slightly pull and push the connector, the 5V rail now measure around 4.96V.

Without changing to spare PSU, i guess it could be due to either loose or oxidised contact on both the mobo and PSU end. So what i did was unplug all the cable connectors on both end and replug it for 3-4 times try to let the contact friction scratch away oxidation layer if any.
BINGO, after done all the multiple unplug/replug work, the 12V and 5V reported by mobo during stress test now become 11.98V and 4.96V, and no more shutdown/stuck reboot issue almost 2 hours now.

I think the problem is the contact resistance increase due to pin oxidation, at both PSU and mobo/GC end, especially PSU end which i don't really unplug since i built the rig few years ago, causing excessive voltage drop when high current pass-through. This is why something you don't touch would fail like what SSJBen mentioned.

Lesson learnt, occasionally touch it even is unnecessary.  

Currently have X570 mobo + R5 3600 + 16GB ram.

Working with Adobe Photoshop/Illustrator and occasionally Premier/After Effects.

Am feeling the proc "could" be a lil better. Am not really sure which/what to upgrade first for best bang for buck upgrade at the moment.

Or is sticking with AMD still the right way forward.

Changed to 5900x, so far satisfy with the performance. Same programs open and cpu utilisation only 50%.

Is it okay to pair 5800X3D with air cooler like Dark Rock Pro 4 or must use AIO water cooler?

I'll check for complaints first. More than 1 year of Zen 3 is enough for me.

I wait till my neck long for 5700x last time.

$399 is $100 more than 5700x launch price, this price is competing with 12700k but whether it can perform better or not.

Will this applies to all x670e boards ?

Ergh kinda tempting to get the 5800X selling cheap in Aliexpress, at 600+. Yea no warranty and stuff, but the last 2600 I bought (which my friend also bought) still works fine. As long as it comes in 1 piece with no bent pins etc..

Not sure if my current cooler can cool it though..

exactly why I highlighted AM5. I didn't have a smooth experience on AM4 compared to LGA1151.

Yea and when looking at benches, there's really a marginal benefit considering my use of light gaming and general work/browsing etc, anyway. But that.. unexplainable itch of upgrading..
I understand some people had horrendous experience with AM4, like all those USB issues - but I started with 2600, then bought a 1200 cheap for my son's build, then upgraded to 5600 - pretty much no major issues, actually. Also build a few PCs for close friends and family - all seems fine.

I just want 5800X3d to drop in price. Will it happen ?
