Yeah I know I said I was done... but


Q - Are these all PCIe cards?


I think there might be something to the PCIe revision on the MB and the card itself.

If they cards were not 100% backwards compatible with older PCIe interfaces...

Or if Nvidia played some games in the card bios to get them to work, is this just the perfect storm in AC that unmasks the evil glitch.


Fact all bugged cards are not 65nm platform.

Fact all nonbugged cards had a backwards incompatibility with PCIe interfaces.


Has anyone actually submitted to a person, not a forum, on Nvidia's support site this bug and pointed them at the wealth of data we have here and on the AC boards?


wubbie - not really here

Ok someone has posted issues with a card thought to be unbugged.


New line of question


What Revision of the PCIe interface does your motherboard use.


wubbie - its like a scab I can't stop picking at it...

This is what it says in my motherboard spec:


PCI Express Bus SPEC V1.0a compliant; supports CrossFire Technology


Hope this helps.

I can't seem to find what PCI E spec my MB conforms to. My mb is the Asus PK5 http://usa.asus.com/products.aspx?modelmenu=2&model=1637&l1=3&l2=11&l3=534&l4=0


I downloaded the manual and I can't seem to find it in there either.


EDIT: I found a review that claims it's v1.1

Hurrrrrmmmmmmmmmmmmmmmm.....


It makes me curious...

Very Very Curious...


someone shake the trees and get other people to post their info...


This could lead to yet a new hypothesis

Oy people of the shimmer....


If you have the bug there are 2 things I'm trying to find out now.


1 - What is the revision of your PCIe interface.

This is sorta a complex question, as there is no easy way to find out it seems. Try googling your motherboard for a review.


2 - Are you running Intel or AMD.

 

-----signature-----

1. V1.0a

2. Intel

PCIe: 1.1

Intel

I'm running an Intel X38 chipset motherboard with PCIe x16 graphics and support for PCIe 2.0.


As mentioned previously, I've had this system (with an 8800GT 512) for a couple months now and have never experienced any problems (flickering) with AC.
