Graphics Card upgrade problem in ML370 G4

I have an ML370 G4 which has 2 PCI-e slots and 4 PCI-x slots. My plan was to upgrade the graphics on the server by installing a Geforce 6200 PCI (not PCI-x!) card. However when I do this, the server does not output from either the graphics card or the on-board output.

When I try the same graphics card in an ML370 G2 (with non-PCI-x slots) it outputs fine. This would suggest that the card doesn't work in a PCI-x slot but I was under the impression that PCI-x is backwards compatible with PCI and should, at worst, slow down the other PCI-x slots. Is there an option on the ML370 G4 to slow down the PCI-x inputs manually instead of relying on the server to do it?

Any suggestions would be welcomed.

Hello Mike,

You are half way correct.

PCI X are backward compatible.

That means, you can Use a PCI-X CARD on a PCI slot, & it will work on the PCI slots speed.

You have a PCI card on a PCI-X slot. This wont work !!

Re: Graphics Card upgrade problem in ML370 G4

Something else has just occured to me about this compatibility problem...

I have two other PCI cards in this server; a Hauppuage TV card and a SoundBlaster card, and they both work fine. I have tried removing these cards to see if it resolves the problem, but it doesn't. Surely these cards wouldn't work either if PCI cards were the issue?

Thats interesting mike, you mean you have 2 PCI cards working on PCI-X slots ???

Ya Mike, I went through the links.

I think VOLTAGE used by these Card plays an important role here.

Couldn't find the usage for the cards you mentioned !

Does the ML370 BIOS have any configuration for voltages or other relevant settings? Or is this the end of the road for this graphics card in this server?

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..

Re: Graphics Card upgrade problem in ML370 G4

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.
