Overclock causes strange network behavior

Hi all, I have an Asus p8p67 pro and 2500k, I overclocked it manually in the bios and it's been like this for about 7 months or so. But there is a strange side effect I would like to fix if possible. Every time I reboot, it loads windows and then just as it is about to connect to the network, the PC locks up for about 2 minutes. Then suddenly it comes back to life and connects to the network and everything works fine from then.

I also noticed that if someone turns the router off, my whole PC becomes unresponsive, just because the network connection dropped. Then if the router is turned back on the PC springs into life again instantly.

So it seems the overclock has caused some issue with the network chip, I guess? It still works it just freaks out every time it starts up or disconnects. Any ideas how to make this better? Thanks 😀
 
It does not look like this is from OCing. Why don't you verify this by reducing back to stock clock and let us know.

Thank you 🙂 I was pretty confident it was the overclock because it only started happening right when I first overclocked. But I will try going back to stock clock just to be sure. I'll reply as soon as I get a chance to do it.
 
I finally got around to going back to default speeds, and the problem has gone. So it definitely must be some issue when I overclock, it somehow disrupts the network on the motherboard. And yet it still works, it just takes forever to wake up and reset.

Any ideas on this? I will do a support ticket to Asus in the meantime.
 
I had to raise it a little bit to keep my overclock stable (I go all the way to 4.7 ghz). Seems fine apart from this one issue though. I sent a support request to Asus, hopefully they will get back on monday.
 
Asus replied and said they can't support anything to do with overclocking. The network issue is definitely better now I'm on stock speeds but I miss the performance from the overclock. Anyone know anything I could do about this? I OC by increasing the ratio and the voltage slightly, wondering if maybe I should increase the bus speed slightly too? Or more voltage or something? So strange how the network still works, it just takes ages to start and stop.
 
Learning how to get a stable overclock out of a chip is a bit of an effort and something you learn how to do over time.

Asus will make things to allow you to do it, they aren't going to stick their necks out there telling you how.
 
What do you think it could be? The oc seems stable because it passes stress tests and I've never had a lock up in many months of gaming. Only issue is the network thing.
 
Does your WiFi come from a PCI/PCIE card? If so, do you happen to overclock those buses too? Maybe you get an unstable PCI card at 35MHz.
 
Thanks guys!

Driver appears to be latest. I think buying a network card could be a good solution, I didn't even think of that but I'm pretty sure I have a spare pci slot and they are pretty cheap so I'll check it out 🙂
