I'm using win 7 64 with an i7-870 cpu with a stock speed of 2.9ghz, and a asus p7p55d pro mobo. The mobo came with a peice of software called Turbo evo which allows for easy overclocking. I set the OC to the max which is 3.5ghz and the system seems stable, but for some reason I've lost my internet connection. Is there any reason why the OC should affect my wireless internet connection? Thanks to anyone who can offer some advice.

So, you automated your overclock and immediately went straight for the maximum allowed? Two mistakes right there.

You didn't offer much information on your overclock, my first guess is that your automated overclock jacked up the BCLK and blew something up (i.e. your wireless card, or the interface it connects to).

What type of wireless card is it? Built into your motherboard? USB? PCI-E? Other?


Open your Start menu and search for Device Manager.
Expand Network Adapters.
Is anything there?
Any Unknown Devices elsewhere in your Device Manager?

no no, I did increase the oc slowly. It's only at the max level of 3.5 that the internet stops working. When I drop back down to stock the interent connects fine again so I don't think anything is damaged. I'm using a pci-e wireless lan card. the only other 2 things under the network adapter is microsoft miniport adapter and pci-e family controller.

Glad to hear you can revert without problems.

However, you've almost confirmed our suspicions.

If your CPU overclock is being done through the BCLK, you're inadvertently overclocking other motherboard components, including your PCI-E buses, dangerously so.

Thanks for the input. The internet seems to be connecting fine now, even with the overclock. Not sure what changed. I'll keep a close eye on things to make sure everything is stable.
