What is PCIe 3.0 x16 @ PCIe 1.0 x16?

Recommended Posts

Posted · Original PosterOP

Hello! 

My graphics card is Palit GeForce GT 640 1GB, and it should normally run at PCIe 3.0 x16, but when I look into BIOS it says: PCIe 3.0 x16 @ PCIe 1.0 x16. 

 

In Windows 10, GPU-Z says: PCIe x16 3.0 @ PCIe x16 1.1. 

 

My PC:

1. Motherboard: Gigabyte Z390 Aorus Master (Latest BIOS version: F11c)

2. CPU: Intel i7-9700K

3. 32GB DDR4-2666

 

Is there a way to make it run at PCIe 3.0 x16?

run the render test in GPU-Z. it's right by the info box.

bandwidth is cut to reduce power, since the card is at idle. when gaming, it'll be @PCIe x16 3.0


I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

 

Primary PC:

i7 8086k (won) - EVGA Z370 Classified K - G.Kill Trident Z RGB - Force MP500 - Jedi Order Titan Xp - Hyper 212 Black (with RGB Riing flair) - EVGA G2 650W - Black and green theme, Razer branwashed me.

Draws 400 watts under max load, for reference.

 

Linux Proliant ML150 G6:

Dual Xeon X5560 - 24GB ECC DDR3 - GTX 750 TI - old Seagate 1.5TB HDD - Dark moded Ubuntu (and Win7, cuz why not)

 

How many watts do I need? Seasonic Focus threadUserbenchmark (Et al.) is trash explained, PSU misconceptions, protections explainedgroup reg is bad

this is correct. GPU-Z should tell him this in the little tool tip, or in the render test.

Thank you! 

Yes, by running the render test, the bus interface changes to: 

PCIe x16 3.0 @ x16 3.0.
