Question about PCI-e Extension cables

[kevinm]

When using 16x16 extender cables to distance the cards the mobo, is it normal that one would get the following message in win 7 device manager:


"This device cannot find enough free resources that it can use. (code 12)"  ??

does it mean that the cables are no good or is this normal when using extenders.

I am only running 3 x 7970's off of an ASUS P8Z77-V Pro mobo. PSU is a Coolermaster 1300W Gold.

Any advice much appreciated,

Kev.

I had this same problem after moving around some cards on my Gigabyte 970A-D3.  Unfortunately the only way I could fix this issue is by doing a system restore to an older point in time.  If anyone has any more details why this happens let me know

I am trying to use 3x5970s and 1x7950 on this motherboard. everything was working perfectly until i tried to add a fifth card

this has nothing to do with cables. 2 devices are conflicting, trying to use the same memory address for I/O probably

go into the BIOS and disable unused hardware listed.. enabled devices are allocated resources (interrupts, memory ranges, sometimes DMA channels) even if not used.

tell the bios your hardware should be managed by the OS, not BIOS. or, if it already says that, switch it to the other

if that fails, try changing card slots.

what cards are you running, and what mobo? OS version?

EDIT here is microsofts take on error code 12

Two devices have been assigned the same input/output (I/O) ports, the same interrupt, or the same Direct Memory Access channel. The assignment was made by either the basic input/output system (BIOS), the operating system, or a combination of the two.

Vapourminer that's a good idea..

Gigabyte 970a-d3.

 I fixed the problem by switching to a 20cm Extender from a 30cm Extender and reinstalling all the drivers on Vista.

good deal

might of been the reinstalling the drivers and/or removing/reinstalling the card switched things around to work,but you have it running so dont do it just to test that

I edited my 1st reply to you to link to and gave a small quote from microsofts explanation for error code 12, the link is worth a read, especially their suggested fixes.
