Will Overclocking the PCIe Lane damage a motherboard or Video card?

post #1 of 14
Thread Starter 
i just read on Google that if you even touch the PCIe bus it will kill your motherboard and video card slowly is that true?

*shrug* everything I've read has said to lock it at 100 and the highest oc was like 104 and then you still risk destroying the card...
But I dont personally know

Well here is the thing...there is no reason to overclock your PCI-E bus anyways so why even worry about it. But its obvious that running anything out of spec they say there is a possibly of killing a electronic device cause it wasnt made to do that. And there is no benifit if you are overclocking it anyways for a video card.

Unless you got some raid card that is saturating the bus and need it to go faster it should bump up the speeds theoretically, but idk.

it was only OC for like 65 hours thats not enough to cause serious damage is it? 90% of the time it was idle or off (the PC)

Pretty sure the worry is more about corruption of data than dying video cards, but what do I know. (aren't PCIe and SATA clocks tied?)

Yes the sata, ethernet, and usb ports are all connected by pcie buses. Since they can transfer data very quickly with low latency. And it will cause all sorts of corruption if it cant handle the increase in speed.

I would say no if I didnt know any better but in experience it will. I killed a 8800GT on a P5B Deluxe by upping it to only 102, after that reboot nothing, I didnt think it died but I tested it on a freinds system to confirm.

overclocking a PCIe bus is not suggested for obvious reasons but the only reason you should ever have to is when you are going for extreme overclocks. and even in that case, 100 to 103 is all you really should do for the sake of safety. some people have gotten higher but it is at a very big risk.

why would a motherboard manufacturer even add this function? seems kinda stupid if all it does is damage things.
