DL 38x G5 PCI-X riser card at 133 MHz even with 2 cards

Hi,
I struggle now for 3 month with HP support about a reproduceable server crash if I add 2 PCI-X cards. Funny enough the server management (ILO) recommends to replace the RAM. (log message (Uhhuh. NMI received for unknown reason Dazed and confused, but trying to continue.), RED LED, yellow LED on the first RAM bank)
After 2 month it was clear that the DL 38x G5 PCI-X rise does not switch from 133 MHz down to 100 MHz. This is recommended by PCI-SIG and other vendor and even other HP machine do so.

So I wonder if other user of HP 38x G5 have similar problems.
For sure there are cards which are running fine with 2x 133 MHz on this shared bus.
But on the other side there must be a reason why PCI-SIG recommend and introduced the 100 MHz option.
