No LAN connection when I increase my CPU speed, no matter how small the change.
No LAN connection when I increase my CPU speed, no matter how small the change.
I'm using an i7 5930K with a base clock of 3.50GHz, 16GB GSKill 3200MHz DDR4 RAM, and an MSI X99A Titanium motherboard. After overclocking the CPU everything functions properly, but my onboard LAN vanishes and I can't locate any networks even when connected via Ethernet. I've tried various fixes but haven't seen improvement yet. It seems my motherboard drivers might need updating, though I'll verify later. Overclocking was done in BIOS. Let me know if you need help.
I’m not overclocking, but I can help you understand how to do it if you’d like!
Just a quick thought, maybe you're looking for something simple. Cards aren't super costly, so you could grab a decent 10$ card and fit it into your PC. That should help offset the issues with that 22nm chip. Since it's similar to 14nm in voltage needs, you can use the standard 14nm max voltage of about 1.52v. The danger zone is around 1.9v, so if it drops to 1.7 or lower, it's still okay unless you notice overheating. Voltage matters less than temperature—keep things under 85°C for safety. If you push it to 1.5v+, aim for below 80°C, ideally around 75°C. Temperatures above about 115-120°C can cause problems, though running at 1.75v over 100°C is possible but risky. In practice, CPUs designed for 45nm handle higher voltages safely, and even at 1.7v on LGA775 they can survive a bit longer. I’ve seen people push 1.75v over 100°C without issues, but that’s a trade-off. Just remember, staying cool is key to avoiding damage.
I've been advised that 4.5 @ 1.34v works well for an OC on a 5930K, but I haven't tested it yet since this is happening on my onboard LAN. It's unclear whether the boost comes from the LAN or if a driver update is needed.
It seems you're noting that at certain frequencies, CPUs start showing diminishing returns—typically around 1.3v for most processors. Going above that usually yields little extra speed, though your E8400 runs at 1.34v and 4.3ghz. After about 200-400MHz, performance improves slightly but cooling remains important. For safety, aim for a voltage near your device's maximum and a -0.3v margin, which gives a stable "safe" range. For your 45nm chips, that’s about 1.75v; for your CPU it’s around 1.6v. If Intel suggests 1.52v, go with that unless you’re comfortable with higher voltages and heat. Your plan to buy a budget GPU might not be ideal unless you’re okay with those trade-offs.
It seems you're testing it with a Corsair H80i GT v2 and keeping the settings low—never exceeding 75% during gameplay or editing.
