I don't know if this is the right forum but ill ask anyway.
i bought a tower a few weeks ago and only got around to checking things out.
i only noticed i have 3 pci slots x1 x2 x4 x16
my question is this knowing what PCIe is i know anything below 16 is not for powerful graphics or sound but more for a legacy modem or something, is it possible to boost these small pci slots. is there no way to boost th x4 up words nearer to x16 if you catch me so i could use my only pcie x16 for graphics and my adapted x4 for something more powerful than a legacy :hello:  modem?
any answers appreciated

No I have PCIe x1 x2 x3 and one x16 which would b normally used for say high end graphics or something that needs the x16 slot. Its my understanding that beside my x16 I can't use the mini PCI x1,2,3 for anything more powerful than a modem, is that correct?
Like sayi want to use the pcie x16 for my high end graphics what can I put in to my smaller slower pcie slots? And is there any adapter or cable I can plug into my say pcie x1,2 or 3 to b able to use it for the same purpose as the x16 slot?

You have 3 pcie x1 slots, which should be named like pcie_x_1_1, pcie_x_1_2 and pcie_x_1_3 or something like that. Pcie x16 slots are very fast(hundreds of GBps), you generally dont nee that speed. Pcie x1 sure is slow but even those speeds are not fully harvested by most cards.
In short you can put a lot more than just a internal modem.

We're also told that based on this data rate expansion, "it is possible for products designed to the PCIe 3.0 architecture to achieve bandwidth near 1 gigabyte per second (GB/s) in one direction on a single-lane (x1) configuration and scale to an aggregate approaching 32 GB/s on a sixteen-lane (x16) configuration." A lot of technobabble, sure, but one thing's for sure: your next graphics card is bound to murder your current one if paired with a PCIe 3.0 motherboard
