About the PCI BUS...

[SoMBrA]

Hello there! i just joined the community

I'm posting here because i've been searching around and couldn't find a solution to my problem.
I own a DFI Lanparty UT nF3 250 GB and i think it has PCI 2.1 (users manual talks about PCI Slot.. doesn't specify anything else) and i just found out that many TV cards require PCI 2.2 or 2.3...
I googled a bit and discovered that PCI 2.1 can work at 5v (but some sites say that they work between 3.3 and 5), then that the 2.2 work between 3.3 and 5 and finally the 2.3 that work only at 3.3v

Questions now:
PCI 2.3 based card could work and my board? (2.1)
My guess is that it should work if google is right, telling me that my bus supplies between 3.3 and 5. If so...
What's the difference between 2.1 and 2.2?

What i have clear is that if you PCI has 2.3 PCI slots then u wont be able use PCI 2.1 based cards as they need 5v to work and your PCI would only supply 3.3... doubts are between "old" boards with 2.1/2.2 using 2.3 designed cards...

Well hope you understood me!
Thanks in advance.

According to http://www.nvidia.com/page/pg_20030918437537.html:
(NVIDIA's Nforce 3 tech specs)

PCI interface
Integrates a fast PCI-to-PCI bridge running at 33 MHz. It includes an arbiter that supports six external master PCI slots. Features of the PCI interface include:
PCI 2.3-compliant, 5 V tolerant
Supports six external PCI slots at 33 MHz
Supports six bus master arbitration
PCI master and slave interfaces
Supports both master-initiated and slave-initiated terminations
Bidirectional write posting support for concurrency
Flexible routing of all four PCI interrupts
Supports read ahead: memory read line (MRL) and memory read multiple (MRM)

I think you are in the clear on this one.

Thank you guys
I've been posting/reading other forums i for what i've read i think guys were having those problems i mentioned because they had no bios up to date, and maybe other hardware issues (IRQ conflicts etc...)

I will buy the pci card and update the post in a couple of days, will let you know what happend finally

Phisrow next time i will check chipset manufacturer website aswell
