Hey everyone! My friend upgraded his old I5-2400 with a really powerful motherboard (Asus P8P67 Deluxe). But things didn’t go as planned. The temps kept soaring—sometimes hitting 99°C for long periods, and possibly even months at low voltage. Even though he ran the CPU at 4GHz, it wasn’t stable. In BIOS R15 it only reached about 501 MHz, which was way below the expected performance.

He managed to get the CPU clock up to 38x105.3 with 1.3V, high LLC, and boosted current settings, but it only worked around 3.85GHz or so. The issue seemed to be that under load, the multiplier dropped to 36x, so he adjusted and tried 32x125. However, even then the system would only boot at around 105 BCLK or less, and it kept resetting to 1.103V after attempts.

He also tried lowering RAM speed and changing timings, but nothing helped. After several failed attempts, the motherboard would show an overclock failure message and reset to 1.103V even when he tried higher voltages.

I’m wondering if the CPU is failing, the motherboard is damaged, or if there’s an issue with the RAM. The 1x8Gb DDR3 seems fine, but I’m not sure what’s causing this instability. Any advice would be greatly appreciated!

The value 99c prevents overclocking. Keep trying?

Just grab a 2500k or 2600k and a top cooler instead of pushing the overclock.

I understand you're double-checking something thoroughly.

The CPU isn't overheating anymore thanks to a better cooler, with a peak temperature of 61°C. It doesn't throttle the thermal output. However, this shouldn't stop the gradual wear and tear now.

You're absolutely certain you don't understand why 4GHz would make such a good boost for that component.

I don<|pad|> a 3.5Ghz is working now, he mentioned he’ll purchase an I7 later.

I believe a daily frequency of 3.5ghz is quite reasonable. If this becomes unstable soon and a lower clock stabilizes, that would indicate a decline in performance. Reaching 4ghz merely stresses the system heavily.

It seems the decay rate is approximately 3.8Ghz. Since the clock didn’t drop significantly under load, there were no 4+Ghz on-chip signals, likely indicating the maximum frequency.

Many 4GHz models use that chip, but most mention air cooling or large water loops. The max temperature stays under 72°C for stability at 4GHz. A junction temperature above 100°C causes throttling.
