Overclocking question

[shockwave88]

Hi there

I am sort of confused. When you overclock a video card or a cpu how does it make it faster if the bus speed stays the same? like it may make the video card faster but does the bus speed increase aswell? cause if the bus speed doesnt increase then the amount of data stays the same not making it faster o.0

any help would be appreciated!

AFAIK, when it comes to PCI-express 2.0 video cards, the bus is plenty fast to begin with. PCI-express 2.0 still hasn't become a bottleneck to this date. Granted, sometimes the video card's memory bus does bog down the card. It's all very complex, and I still don't really know how the whole thing works, but in general, I don't think the bus is too much of a problem. Even when it is, you'll still see a performance improvement by overclocking.

for the bus, i mean it's in a x16 slot, and when people put in a second in the x8 slot the cards still perform at like 90% or more, so i think there's plenty of bandwidth on those slots, still not sure why they already have 3.0 out.

PCI-E 3.0 is out because at X8 it is as fast as PCI-E 2.0 x16 - meaning you can have less lanes with the same performance. The performance increase from going to 3.0 X8 to 3.0 X16 has yet to be seen.

Maybe we'll find out with the Radeon 7000 series.
