Question PCI Link width is 4x, but should be16x -

[Jerethi]

Greetings,

I have a Gigabyte B360 HD3 motherboard, with an MSI 1030 GT graphics card that supports PCIe 16x 3.0. The graphics card is plugged into my PCIe 16x slot, but is only operating at 4x. According to the motherboard manual, this slot does not share bandwidth with any other slots, so I can't understand why I'm not getting 16x speeds. Anyone have any ideas?

Everything is ok, GT1030 only support 4x speed.

Honestly it wouldn't need more than that. The tests on the 6600XT showed that even if you ran that card at PCIe 1.1 specification speeds you still only lost ~15% performance.

The 1030 is another tier below that card.

The video card itself is a 4x card, so running as expected.

Ah. What a rookie mistake on my part. Confusing the link width with the bus speed. But then again it is kinda confusing that they use the same measurements...

No, the slot is capable of 16x, but your card is only capable of 4x. The width of the physical interface is the same. Why wouldn't they use the same measurement when an interface is a two way street?

Right. What I meant was that my video card has a 16x slot even though it only supports 4x, so it can be a little confusing to distinguish between the slot length and the speed. But, like I said, rookie mistake.
