Edit updated links to 2701
bios 2701, names in links
fixes some bugs and raises settable fmax offset.
this is still based on the same AGESA version as 250x so dont expect any difference in Fclockiness against that version.

How does low power state effect performance, care to explain this statement ?

It's from info provided by The Stilt on overclock.net:

"So regarding the idle restart issue, aka "Event 41" problem:

Based on the testing, disabling option called "DF CStates" found in AMD CBS-menu (Advanced / AMD CBS / NBIO Common Options / SMU Common Options) should solve the issue.

The CBS-menu also contains a second C-State related option (Global C-State Control) that has some redundant functionality and can be used as well however, if this option is used it will negatively affect both the CPU power consumption and performance as well. Because of that, the "Global C-State Control" setting should remain at the default "Auto" setting, while the "DF CState" -setting should be disabled.

Unless the user encounters the idle restart symptom associated with the "41 code" events in the Windows Even Viewer, there is no need for the user to change this setting.

Both the problem and the fix are universal, and not either ASUS or Crosshair VIII specific."

Just a heads up that in "2. Disable CPU C-States & DF Cstates under Advanced-> AMD CBS" you might want to try disabling C-states first and see if that fixes your issue/s as the cost is a relatively minor impact of around 7W to 8W on your fabric power consumption at idle. Disabling Global C-State Control will adversely affect the performance of your CPU.

Thankyou,
i will try as soon as i can.

Sorry RedSector73, you're right.
This is my config:

So, if i correctly understood, yout system is stable when you enable the "idle states " fixes.
What's the latest bios you can run stable on your system without disabling or limiting power saving features?

Thanks

Hi RedSector73 i would like to fill my system config in my profile, but i can't.. al fields seems to be note editable.

By the way, playing with 3003 bios i was able to keep system stable with fclk_max=1600Mhz. Fixed the fclk frequency to 1600Mhz i can set my rams at 3600Mhz with no issues or wheas notifications in HWinfo (so without system restarts).
Of course, i would not leave out of sync fclk and ram frequencies, so i'll keep investigating on the problem.

So lowering cpu core voltage with -0.05V bias anda PBO Enhancer enabled and the above ram settings, i get these results with CPUid and no system errors:

@DrSlump76 I'll state it again never had BIOS issue, 3303 is working as intended without applying any c-state fix, this has worked for others with issues.

Please fill in your PC specs, it helps us, to help you.

Hi RedSector73,
sorry for the late response.
I'm actually trying to fill my system specs on my profile page but maybe there is some problems with that page because i don't see any button or any other field to fill.
Please you may find my system specs on following CPUid link:

Thankyou very much

How old is your PSU? Just had an AX1200 go south on me after moving to a 3080 Aorus. Wouldnt throw bluescreens just hard reset. Also was annoying to nail it down as I could stress test the CPU and GPU all day seperately but as soon as I fired up a game it would randomly reset. Sometimes instantly sometimes after 5-10 minutes. Replaced it with an AX850 Titanium and haven't had a problem since. My AX1200 was just over 10yrs old so it served me well.

Psu is less than a year old I've had no issues with it yet it it whines a little but that's normal for this model. It was previously running a 10900k @ 5.2Ghz and rtx 2080 ti with no issues

Is there any way of confirming the psu?

I can game for 6 hours sometimes without an issue or I can game for an hour and boom restart
