System overheating and instability following the BIOS upgrade.
System overheating and instability following the BIOS upgrade.
I've been using the same BIOS since 2019 and noticed some improvements on Asus' site. After updating my PC, it's been getting hotter and isn't stable anymore. The previous version was 5204, now it's the latest non-beta 5809. Before the update, I was running at 4Ghz @1.318V with temperatures around 35°C idle and 50°C during games, peaking at 68°C under heavy load. Now idle temps are up to 45-50°C, and games run in the 60s, sometimes hitting 70s. My current setup isn't stable below 1.36V, and even at 3.6Ghz it needs 1.3V or more. I'm looking for alternatives besides reverting to the old BIOS. Thanks.
Specs: Windows 10 20H2, Ryzen 7 2700, 240AIO ASUS Prime X470 PRO, 32GB RAM, 2400MHz EVGA 2070 Black Seasonic 750W Gold PSU.
OC settings: Voltage 1.318V, 1.36V (managed), power phase optimized for CPU and SOC. Extreme settings didn't help stability. Load line is Level 4, Level 5 increased heat without improving reliability. Current capability is 140% SOC, auto SOC at 110%.
I had the same issue with my ROG STRIX Z370-F Gaming, and I'm curious about what might be causing it.
The toughest issue is that my PC is located in the finished basement, where the temperature is around 18°C. Just a few months ago I changed the thermal paste from the standard cooler kit to Thermal Grizzly Kryonaut, which made things even better.
Running the XMP profile requires verifying the CPU SOC voltage. If it exceeds 1.08v, reduce it. At 1.08v it's acceptable to lower it further. My board didn't show this issue, but I used 4100mhz at 4.100v. On other BIOS versions, I ran 4000mhz at 1.38v and found instability when pushing the CPU to its maximum P-state (3.7ghz base clocks) with a v-core of 1.212v. That was across all revisions. No clear cause identified—possibly the v-core is insufficient for manual overclocking. The chip is otherwise functioning normally. Consider cleaning the cooler or tweaking case fans, assuming fan profiles reset after a BIOS flash.
soc is operating at 0.89v according to the AI suite. I chose to test stock performance, which idled around 29°C. However, I experienced a potential CPU issue—my BIOS decided to halt all fans, including the CPU and AIO pump, while gaming, pushing my CPU temperature up to 102°C. Now I’m talking to ASUS support to understand what’s happening.
Sadly I previously attempted that and received the message "specified file is not a valid bios." Likely, since the latest bios only supports versions 3000 and above, I can't choose an older one...
Update: Asus told me to flash the latest beta bios. Unsurprisingly there has been no real improvement. I reported back the issue with the fans and the response was "it's normal for GPU fans to run at low speeds or shut off if the temps are ok...WHAT? I never once mentioned to them anything about my EVGA gpu...this has been entirely a case fan/cooler issue...AI Suite doesn't even touch the GPU. If anything the fan side of things is worse...the fan control is literally inverted. if i set AI Suite to the full speed setting it fully shuts all fans off including the CPU cooler. luckily i have the AIO header control disabled so there is still fluid flowing and it isn't controlled within AI Suite anyways but this is a major oversight on their part. If i didn't know what i was doing could cost me over $500 to replace dead parts from thermals going nuclear... attached is a screen recording of what is happening that i sent them. hopefully one of the techs over there knows what the hell is going on otherwise i'm buying a new mobo from a different brand and not using ASUS again... 447633984_2021-01-2423-16-13.mkv
I tried using Windows Power Management troubleshooter for the fan problem, but it didn’t help. They suggested flashing back to the original 5204 BIOS before updating, which I couldn’t do because the BIOS wouldn’t allow it. I spent a lot of time fixing it myself and discovered the issue was actually AI Suite 3. After uninstalling it, all my problems except stability disappeared. I’m hoping they will reply to my latest email with a solution since it seems no one should be better than the trained support staff.
Final update: ASUS decided to close all three tickets, claiming you were on your own. You ended up getting a new motherboard—an MSI MAG X570 Tomahawk. The $320 was worth it; you managed to run your same overclock at lower voltage, and your memory also improved. Interestingly, your 2400 sticks had an XMP of 2933, which the ASUS board didn’t recognize.
