PCI limit reached - pci latency

bill3107 · Post by **bill3107** » Thu Sep 14, 2006 5:43 am

as i have sometimes "PCI limit reached" messages (pci overflow) with my brand new P100 (if used with minimax or 4080L for example), i was just wondering what have you done, guys, to cope with this problem? I have found out that my default pci latency is 128. I have tried several numbers (64) but that does not solve my problem.

This thread could be great for explaining what are the tweaks that really work ! All those who use Minimax or P100 stuff should have some great ideas?...

in BIOS, disable everything unneccecary like COM ports, Onboard audio etc.

Disabling onboard sata (on Asus A7N8X E-Deluxe) did the trick for me.
Before that, I had this "Pci capacity limit reached" any time disks would be accessed.
I can now run a couple STW P100 without troubles.

Today, I tend to use the light version more often than the full one.

what kind of creamware cards do you use? Type 1, Type 2? How many DSP's? How many S/TDM-Cables if multiple cards?

If u use only Generation 1 Boards, the PCI bandwith is less than the generation 2 boards. and the a100/p100 needs lot of pci bandwith...

I have done everything recommended in this thread and still receive the same error messages when I use the otherwise excellent Sonic Timeworks reverbs. Would be nice to fix this problem.

Try using a PCI Latency utility to give Scope a longer access time on the PCI bus.
Here's a couple of options:

On my system, all PCI devices had a latency of 64 (Mboard bios default). I increased the Scope devices to 96. This stopped some PCI overload messages I was getting.
There's a lot of discussion about this on this forum - it seems a lot of Mboards don't need PCI latency tweaks, but with my board (Asus P4C800) it made a difference.
