Adjusting PCI overclock from 2.0 to 3.0 speeds?
Adjusting PCI overclock from 2.0 to 3.0 speeds?
You won't be able to achieve that high speed easily, as reaching a PCIe rate of 200MHz isn't feasible and would likely cause problems.
It doesn't make sense. Wouldn't people have praised PCIe overclocking much earlier if it were real?
I was just wondering if you'd be interested in it once it becomes stable.
Also check out what @Electronics Wizardy, @AbydosOne, and @aDoomGuy shared. Remember to avoid overclocking PCIe slots.
In theory it could work, but it would cause frequent crashes and the benefits wouldn't justify it. If you're determined and manage stability, it could be a success, though I strongly advise against it.
The core problem lies in the encoding used—PCIe 2.0 operates at 8/10, meaning eight bits of data are sent for every ten bits of electrical signal, with extra bits for error checking and padding. PCIe 3.0 is 128/130 encoded. Even with matching transfer rates, the receiving end wouldn't understand the signal format. Additionally, the jump from 2.0 to 3.0 isn't a straightforward doubling; it's about a 60% boost in symbol rate plus encoding efficiency gains that result in roughly a 1.97x speed increase instead of the expected 2x.
