Weird problem, temps drop after sleep mode
Weird problem, temps drop after sleep mode
I also face a problem with a GA-78LMT Gigabyte board paired with an Fx-8320 Processor. My initial concern was that when I first assembled the machine a week ago, the CPU temperatures were extremely high at 60°C. I’ve used other systems with the first revision of this board (Blue) and they functioned perfectly. This one is (blackboard), a different model number but the same revision.
To address the overheating concern, I re-applied thermal paste using the Artic MX-4 instead of the original paste from the stock cooler. This didn’t solve the issue. I repeated the process three times, using both the original and the new paste, just to eliminate any chance of human error. I even followed the grain-of-rice and pea methods when installing the heat sink, but the temperatures remained unchanged.
I had my brother, a certified A+ Tech, perform the same procedure just to be sure. He confirmed that it didn’t make a difference. My airflow was directed through the front opening from the back and in from the sides. I also swapped out fans without any real changes, just to see what would work better.
I was advised to return the board along with the chip. Even though I’ve seen 90% of similar setups fail due to the motherboard, I brought it back with new parts—same board, same CPU—and unfortunately, the results were the same. Eventually, I started checking the motherboard features. Between a working system with the same motherboard and CPU and the problematic one (as I call it), I found that on the blue board, Turbo Boost was set to 250MHz, showing AMD Overdrive, while the black board overclocked to 500MHz with Turbo Boost enabled.
I never intended to overclock either system on a budget board like this, especially without a better cooler. Turning off Turbo Boost brought my temperatures down from 60°C to around 47-49°C, which is still quite high. The actual core temps were between 33-37°C. It’s safer but not ideal. Until I can install a better cooling solution, I’m sticking with what I have.
I’ve been keeping an eye on hwmonitor and forgot to disable sleep mode because of all the other issues I was dealing with. Everyone else is saying the same thing—when I enter sleep mode, it hits 48°C (or a bit higher), then drops to around 37°C when I come back online. It stays in that range during regular tasks like watching videos or browsing the internet.
I tested the temperature differences across three programs: Ada 64 (formerly Everest), Speed Fan and Cpuid, and HWMonitor. All of them showed the same readings at startup and after sleep. Anyone has any ideas on how to resolve this?
This thread aims to mark 4 years since our existence and remains a mystery... Wow... I have to admit, this seems truly remarkable...
Same issue with the Gigabyte 990FXA-UD3 and AMD FX-8320.
Normal startup temperatures are about 24°C. Once resumed from a suspended state, they drop to around 14°C. If the temperature falls too much, I see BIOS warnings and fans stop working. I've configured Speedfan to maintain a certain PWM level to prevent these alerts, but it's still unreliable after resuming. The temperatures aren't consistent, and even the BIOS is giving me trouble.
Similar problem here, experimenting with an OCP and using the sleep button for the first time. Please check that m/b temp 3 (which I labeled core temp + 12) now matches the actual core temperature. Not too worried - seems like the sensors are working correctly after sleeping.
I encountered the same issue with the GA990FXA-UD3 board using an Athlon X2 270. The problem occurs because after the computer wakes up from sleep, the temperature drops to -128°C in Aida64, which causes the CPU fan to stop. This happens with the FDk BIOS (beta version), but it disappears when downgrading to FC.
