MSI z77 G45 Question

[BigCoffeeGaming]

Hey guys I just got an upgrade and purchased the above motherboard. I noticed a setting in the BIOS called PCIe Bus Clock. It starts with 32 clocks up to what I could see was 256 bus clocks. Does this go hand-in-hand with the GPUs bit rate? I'm confused by this setting and was wondering if it's possible to squeeze more power out of my 560ti by bumping this setting up.

Thanks in advance!

PS: Btw I am a past member. Guess the forum does auto purge of inactive members unless I used a previous email. Anyhoo, I was St3v30. Hope everyone is doing well. I had some life experiences that tore me away (was actually a mod at one time). Now things are going great and hope the rest of you are doing so as well. Ta ta for now.

i believe this is related to the latency timer for the PCIe bus lanes.

Controls how long each PCI device can hold the bus before another takes over.
When set to higher values, every PCI device can conduct transactions for a longer​

time and thus improve the effective PCI bandwidth.

but as to improve your PCIe-x16 device, not really. it just gives priority to share
lanes, if needed.​

So a bigger clock will provide more lanes? So 32 clocks is not better than the 256? Kinda like a mouse in that 100 is worse than 1000?

Btw thank you arideano for the answer. I guess I'll play around with it and see if I notice any differences, mainly in gaming to see if it helps with some load share with the CPU.

kinda look at it like seconds..
32clocks = 32seconds, etc...
its a time differential more so than lane provisions.
