My computer starts up strangely when I increase the CPU speed.
My computer starts up strangely when I increase the CPU speed.
Hello!
I noticed an unusual behavior when I pushed the overclock beyond 4.6GHz on my I7 4790K (currently running at 4.7GHz).
System details:
I7 4790K
TITAN X Pascal Hybrid
16GB DDR3 2400MHz
Sabertooth Z97 Mark S
Corsair CX750M
After a night of inactivity, when I restart the system (even though it was completely powered off), the fans spin once, then everything powers back up normally without any further action. It takes about two seconds before it boots again. This happened only after an overnight period.
I’m unsure if this instability is due to the overclock itself or if more power is needed. The CPU voltage is currently around 1.277V. If I shut down and restart the power supply quickly, even briefly, it doesn’t occur again.
When I’m actually using the OS and gaming, temperatures stay below 70°C (with a Corsair H105 cooler) and there have been no crashes. If I leave it unchanged, will this affect the hardware? I’m really confused and don’t find any relevant discussions online. Thank you for your help!
The voltage level seems insufficient...or the power supply might be underpowered and not deliver the required full voltage during startup. Do you have another PSU available, or should we borrow one to check?
The voltage adjustment appears to be insufficient... or the PSU might be weak and not delivering the full voltage required at startup. Do you have an alternative PSU available, or should I borrow one to check?
It seems there was another issue with the BCLK at 102, causing the base clock to jump to 4.08. Could the system only supply the base clock voltage (4.00Ghz), leading to a stall? Then after two attempts, it tries again with a higher voltage—possibly to power the battery and allow the BIOS to read properly. At least this method seems to work intermittently, especially when left overnight, which suggests the battery might be draining quickly. This is just a hypothesis; please share your thoughts!
P.S. I don’t have another power supply to test with, and I can’t purchase one right now.
