ROG B760-F + I7 14700 (non k) instability issues.

I upgraded my old pc (rog b390-g + i7 8700k + 32gb ram ddr4 2400hz) to my actual Rog B760-F + I7 14700 + 32gb DDR5 5600hz and have terrible instability issues since then. Randomly, the system starts with a cracked and distortion sounds and, when it happens, it freezes after a few minutes. Restart the system until the bad sounds is gone it solve the problem. Also, even when the system starts ok, I got a complete system freeze while gaming (I have a RTX 3080 GPU and a Corsair CX 850 PSU). Drivers, bios, firmware and SO (Win 11) are all update. At first i think it was a audio problem and try a ton of solutions found in the internet, but none of them work. Now I'll think it's a problem of the CPU/voltage instability, because I run a stressed OCCT test, and got several WHEA errors. All components are ok plugged on the motherboard. Any help to solve this annoying problem, please??? (sorry for my bad English, I'm Brazilian)

Thanks for the reply guyd5, but I think I finally found the solution. 

I'm forgot to mention, but I have a extensor cable gpu to use my RTX 3080 vertically, and this cable is pcie 3.0. Since my GPU is pcie 4.0 and the default pcie options in bios was set to auto, I'm suspect it have some kind of conflict and change to pcie 3.0 on bios, no issues 2 days so far.

Just wait a week or so to have sure if it's really is before close this topic 😃

Just adding that I'll also try a clean windows 11 install and clear cmos like asus support ask me to do, and the issue still persists. Because I have upgrade mobo+cpu+ram all at once, can't tell if it's really a mobo problem =(

If you haven't tried it yet, I think a clean install will be the best place to start. It sounds like you might still be using the old installed OS? Changing the CPU and motherboard without a fresh OS install is likely to cause a number of issues. So give that a try and remember to backup your files, internet favourites, game saves, browser shortcuts etc etc first. Or to save time, you could backup the current OS as an image, then just try a fresh install to see if that helps. If not, you can then restore the old OS again if needed. 

Z690 Hero, BIOS 3401, MEI 2345.5.3.0, ME Firmware 16.1.30.2361, 7000X Case, RM1000x PSU, i9 12900K, ASUS TUF OC 3090TI, 2 x 16GB Corsair RAM @ 5200MHz, Windows 11 Pro 23H2, Corsair H150i Elite AIO, 4x Corsair RGB fans, 3x M.2 NVME drives, 2x SATA SSDs, 2x SATA HDs.

Thanks for the reply, but, as I'm mentioned before, already try a clean windows install and the issue still persists. Pretty sure it's a compatibility problem between CPU/mobo, since I don't understand nothing of that amount of cpu/voltage options in Bios. Also, forgot to mention, but I'm have a corsair h100 watercooler and the temps are OK. 

OK, probably a language issue in terms of my understanding. Have you tried re-mounting the CPU?

It's another thing to try. Check for dirt, bent pins etc. Then make sure that the cooler is evenly tightened, but not over-tight. You could also check around the cooler posts and make sure that no motherboard traces have been damaged. Sorry that I don't have an answer for you, just trying to offer some high-level suggestions. 

There are also a few things you can try to fix WHEA errors which include:

Disable PCI Express Native Power Mgt in BIOS (advanced tab, platform misc configuration)
Disable Native ASPM (Active State Power Management) (advanced tab, platform misc configuration)
Check that power savings in Link State Power Management in Windows (Edit Power Plan/ Advanced settings/ PCI Express/ Link State Power Management) is not set to maximum. Moderate should be OK.
Try running Command prompt "CMD admin mode" and doing a Sfc /scannow

Also "DISM.exe /Online /Cleanup-image /Restorehealth"

Probably doesn't apply to you, but not set PCH voltages too low in BIOS (Advanced/ Tweakers Paradise). Minimum values do work for some, not for me. I find that midpoint voltages work fine.

Thanks again for the reply. 

Unfortunately, none oh the above work for me, the problem still persists. Also, Tweaker paradise was on the Tweaker tab, not advance, but there are a plenty of options to change related to voltages.

Lastly, two years ago I build another setup on this pc (gigabyte b600 + i7 12700 + 32gb ram ddr5) and got the exactly same problem and delivery all components because can't find the culprit, but now that I got the exact the same issue with another parts, i start to doubt. Asus support tell me to activate the RMA, but since it happens with another mobo, i don't want to risk stay all those day without my pc for nothing.

Hi, before doing a clean install, try few quick checks:

1) DDR5 is notoriously finicky - from BIOS reduce speed to 4000 and see if problems go away;

2) 3080 is a big and heavy card. Random blackouts might be caused by its sag. Prop it up, or set PC on its side (temporarily) so card is vertical in the horizontal motherboard.

3) Use free HWinfo to check CPU temperatures with idle or mild load - to help decide if you need to double-check the CPU cooler is intalled tight (but not too tight as that may cause DDR5 instabilities).

and one a longer-term:

4) Asrock have just released a new BIOS with latest Intel microcode improving non-K 14700 work. Wait until @asus takes its sweet time to release the very same intel microcode for Asus boards.
