It's odd to see so many comments without anyone pointing out that the 2400 isn't a K CPU and thus can't be overclocked normally. The only choice seems to be adjusting the BCLK. However, pushing BCLK that high—like to 125—is extremely dangerous; it affects many components, including the SATA controller. It's not worth it because system instability becomes almost certain, particularly if you exceed 105MHz. I recall reading about Sandy Bridge a decade ago and that's why Intel recommends sticking to a 100BCLK and boosting the multiplier instead.
For the first-generation Intel Core i7 (Nehalem and Westmere), such as the 920, it felt like an early HEDT platform, so overclocking was possible since the multiplier could be increased. Checking the CPU listings shows that among mainstream platforms, only the i7-875K could be overclocked, while others had locked multipliers.
A BCLK of 105 is considered the upper limit—103 is acceptable but offers little gain. Performance drops aren't expected, but stability is a concern. CPUs either perform as intended or fail completely. My 12-year-old Core 2 Quad Q9650 still matches its original speed, though it's no longer fast enough for modern games. It hasn't lost functionality or speed relative to its potential.
If budget allows, upgrading to a 2500K or 2600K would be ideal, or building a new system would be the best solution.
I own a 930 and a 980, plus a 980x with some Xeon chips and a Gigabyte board. I've done some solid overclocking, though I'm using an 8°C water delta. It's a great setup!
He didn<|pad|>'s perspective on the situation. Even though it’s locked, there are ways to adjust things if needed. I realize BCLK interacts with more than just the CPU, including SATA drives, which explains why it affects performance. If 105 is the upper limit, then some users manage to exceed 180+ by tweaking settings. My old I7 handled 185Mhz BCLK without issues, though it was unstable at higher multipliers. It’s about maintaining stability and performance over time rather than immediate speed gains. If a CPU keeps running smoothly at high temperatures for extended periods without noticeable drops, it suggests the system is well-managed. Purchasing a new motherboard means he won’t replace the current build, so he’s relying on the existing hardware and its longevity.
I’m also planning to test some Xeon chips, particularly the X5690 in the future. Those 980/980X models are quite costly even today. Would you like to use liquid nitrogen?
No mention of ln2, just not here. I’d need a backup board otherwise. Likely the 980 reached around 5.2ghz. https://hwbot.org/submission/4687323_shr...251.84_mhz
