Can't find "performance enhancer 3" or fmax" on my x570 aorus elite bio's. Any help would be greatly appreciated.
First - thank you and Russian guru for that settings, that stops games from crashing in 2 minutes.
Now I can play for hours, but still crash with WHEA Error 18 remains.
Wandering if anything else can be tuned in BIOS? Mobo is MSI X570 Tomahawk WI-FI, latest beta BIOS.
I've used following:
- PPT 200W
- EDC 333A
- TDC 333A
These values matter a lot, and I can't promise these are the right settings for your CPU and mobo:
Set VDDP - 960 mV (to max of 1.06)
Set VDDG IOD - 1010 mV (to max of 1060mv)
Set VDDG CCD - 940 mV (to max of 1.1v)
Uncertain about ProcODT. (Possibly 40 to 45)
Set SOC voltage of 1.15
Set SOC LLC 3 (I think that's what it's called)
Disable Resizable BAR support
Set PCI_E1 Gen Switch = Gen 4
Set Chipset Gen Switch = Gen 4
Set RAM voltage manually, based on XMP data read from RAM using a utility or whatever (try 1.42v) . Optional: Set RAM parameters, manually - Future: Set GearDownMode disabled
--------------------- The following is not really as important:
IF you have the feature PBO2: Within PBO Curve Optimizer: Set voltage magnitude adjustment for all cores to a positive value offset between 7 - 10.
Can lower down as low as -10 (negative ten) if system remains fully functional during burn in testing.
Temporary: Within PBO advanced settings, Set EDC limit to 200 (might bypass hard locks due to bug. Can set back when new AGESA BIOS updates fixes)
Temporary: Disable PBO AND at the same time, set CPU voltage from AUTO to OFFSET mode and add about 0.05v ! The goal is to target about 1.36 volts at idle.
This helped me fix crashes in game with an Asrock B550m and 5600x. Almost gave up after trying many different fixes that had worked for me in previous builds. I had not even begun to overclock. Thank you!
For my ASUS B550-F (Wifi) and 5800x with AIO all I needed was a BIOS and chipset update from 8/2020 to 1/2021 to fix full system crashing in Apex Legends ready up screen (gaming).
This is with 30 mins of testing, so try other fixes too.
Yes, you can try the various PBO settings, in addition to the default setting "Enabled". On my motherboard, the "enabled" setting works, but it sets the PPT, TDC, EDC to values that I consider too high. When I choose "Enhanced" 1 - 4 , the values are a little better on my mobo. But I really like the option called "Advanced" - "set to motherboard limits". Because, in theory, the manufacturers know better than me. Finally, if you still crash, choose "Eco mode 95w" temporarily, and see if you still crash. I was able to bypass a bug in my system by using the following values: PPT 122, TDC 83, EDC 220. EDC might be on the high side, the defaults should be PPT=140, TDC=85, EDC=142. But I think they use 200 because of a temporary glitch. And I think PPT should be locked lower than default during testing to isolate a bad chip.
Now having said all that. hard crashing under load can also be your RAM or power supply. In my case, I had too or too little ram voltage and after the chips heated up under load, the RAM errors glitched the OS. So I went into BIOS and set my ram to the factory settings, 1.35v, and instead of using the XMP profile, I manually input the first 5 parameters: in my case, CL16-16-16-36-50-etc. And sure enough, after I got the voltage right, and set the parameters instead of using XMP, everything booted. Sometimes you have to clear the old settings that get autosaved in the "AMD Overclocking" menu (area in BIOS separate from the normal settings), just set the parameters in the mobo OC section instead of the autosaved section. After the system was stable, I was able to slowly add voltage to the RAM, and by the time I got to 1.46v I was able to use tight timings of CL-14-14-14-34-44 , roughly. And that sped up some of my operations by 10%. The total system benefit is at least 2%.
Thank you for all your tips.
Just registered here to say the one and only thing that helped was to replace the CPU with another one. Sent back the faulty 5800X to the vendor, got another one from a different vendor with a different charge number (00066 was faulty while 00063 working - but I don't know if this has something to do with it).
All these problems are probably coming from a bad QA from AMD and thus they are selling CPUs that are not working within the specifications.
* BIOS updates did stabilize a little bit - maybe due to adjusted voltages. (MB: Aorus x570 Ultra with F33a BIOS)
* The curve adjusted (to about +15) helped most, but a brand new 460 EUR CPU should not needed to be tweaked or scaled down anyway.
* A new power supply didn't change anything (replaced it just to be sure).
* The new CPU works out-of-the-box super-nicely with top performance without any crash neither in Windows nor in Linux.
My recommendation: Immideately replace your CPU if you have unstable systems like WHEA crashes.
Same issue with my 5600x
Motherboard is B550 AORUS PRO AC
AS i disable core performance boost everything works fine no bsod.
Works fine with manual cpu clock ratio 46 and v core voltage 1.35 but somehow CORE PERFORMANCE BOOST is making it crash.
i have had the same problem.
My PC was crashing while playing certain games. The screen just became black und the PC turned on again.
Strangely enough I had no problems with any benchmarks or certain other games.
Windows was also running stable.
After a crash Windows event log showed ...
WHEA Error - Event 18 - serious hardware error
Reported from component: CPU-Core
Source of Failure: Machine Check Exception
Type of failure: Bus/Interconnect Error
My hardware ...
CPU: Ryzen 7 5800x
Mainboard: ASRock x570 Extreme 4
I fixed the problem by updating the bios/ uefi from v3.00/ AGESA 220.127.116.11 (this was the first version suppporting ryzen 5000 processors) to v3.60/ AGESA 18.104.22.168.
I hope this helps someone..
Rumple answer saved me.
My problem is not exactly the same.
Ryzen 5 3600 with Trident z neo 16-19-19-39 3600.
My problem is that I wasn't able to bring the fabric clock, whatever the voltage combinaison I tried, and I tried a lot.
The settings you provided in the first part are the only one that allowed me to bring the Flck at 1800.
No one ever talked about SOC LLC but it seems to be the settings that changed the game for me !!!
