MP 7,1 MacPro 7,1 pci slot clamping bars not holding

[Trippertipper]

Hi All, anyone with a 7,1 using short pics cards without the tail end hook noticed Apple’s clamping bars do not actually clamp down hard enough on the pci card head end to stop them wobbling in the slot, when you plug something in then you can easily move them up and down .

the Lock mechanism does not affect the head end of the system

my take is it’s an engineering design fault with the bars,

thanks

It might be your PCIe card's bracket came from the factory out of alignment . Just manually straighten the bracket of the card . If it is out of spec , I'll place a small amount of card stock material between the I/O area of the Mac and the bracket of the PCIe card to secure it firmly .

thanks yes actually that’s what i did, I put some thin rubber strip under the apple securing bar pressing on the pci card head which holds it firm , but still it’s a bit of a hack
Happens on 2 pci cards, one a sonnet usb c card so seems to me the clamps are just not deep enough
