Graphics Card upgrade problem in ML370 G4

[Blazhev_1]

Hi,

You can use PCI cards in PCI-X slots if they are universal voltageâ that is, if they work with both 5V and 3.3V voltages. PCI card and slot keys are meant to match signaling voltages. The 5V-only PCI cards are keyed so that they cannot be installed in a PCI-X slot.

The PCI-X slot work only with 3.3 V, so only universal or 3.3V PCI card can be installed and if a 32-bit/33MHz 3.3V card is installed on the PCI-X bus, it automatically
forces all the cards in the same PCI-X bridge to work at 32-bit/33MHz...

ProLiants are not made for multimedia apps, that's why they have so poor VGAs. Normally no optional VGAs are supported, only by some modells NVIDIA QUADRO..

Hi,

sorry for the double reply, there were problems with the post.

In Quickspecs :
http://h18000.www1.hp.com/products/quickspecs/12029_div/12029_div.HTML

under the Expansion Slots section you can see that the PCI-X slots work at 3.3V and the 5th NOTE states :
All PCI-X slots can only accept universal keyed PCI cards running at 3.3 volts.

The voltage accepted is embedded in the chipset, you can't change it from BIOS.
