is my amount of pci-e lanes limited my 2070?

Recommended Posts

Posted · Original PosterOP

my 2070 only have 60-80% load on gaming. My cpu is i5 7500 that have 16 pic-e lanes and my mono is strip b250f that have 12 pci-e lanes. My rig also have a ssd and a hdd using 6x sata. Is my rig do not have enough lanes for the 2070 to get the peak performence?  Or my mobo do not have enough power phases to let the rig stable and perform well?

 

p.s. i also used a z270 formula + 7700k rig to test the card. the card can perform over 90%.

Seems possible that your CPU is bottlenecking your GPU.

Nah, the motherboard isn't the problem. Even with 8 lanes at PCI-E 3.0 speed, it would be still plenty for that 2070. And that card is probably getting plenty of juice from the PCI external power connector, not from the board (the board can only supply 75W maximum through the PCI-E slot). The only problem is that the i5 7500 might be causing just a bit bottlenecking for that card.

the difference of two rig are so big and the 2070 in 7500 rig is not stable at all. is it the lanes or the power problem?

Did you read what I said? I said your CPU is bottlenecking your GPU.

 

It has nothing to do with PCIe lanes or power delivery.

but the performance of the 2070 inside the 7500 rig is almost the same or even worse than my old 1060...

i5 7500 is only a 4c/4t CPU, this is going to likely be your source of issue. If you check your CPU usage, is it at 100%?

Neither, the i7 7700K is simply a much faster and capable CPU than the i5 7500.
