I have a pre-built Dell rig, and after a bit of research I found the following specs:
Code: Select all
Bus type PCI 32-bit (PCI Specification 2.2)
PCI Express x1, x4, and x16 (PCI express 1.1a)
Bus speed PCI: 33 MHz
PCI Express:100 MHz
Bus throughput PCI Express:
x1 slot bidirectional speed - 500 MB/s
x4 slot bidirectional speed - 2 GB/s
x16 slot bidirectional speed - 8 GB/s
connector size 120 pins
connector data width (maximum) 32 bits
PCI Express (x1)
connector one x1
connector size 36 pins
connector data width (maximum) 1 PCI Express lane
PCI Express (x4)
connector one x4 (x8 connector wired as x4 electrically)
connector size 98 pins
connector data width (maximum) 4 PCI Express lanes
PCI Express (x16)
connector one x16
connector size 164 pins
connector data width (maximum) 16 PCI Express lanes
Code: Select all
DC power supply:
Wattage 375 W
Heat dissipation 1280 BTU/hr
Note: Heat dissapation is calculated based upon the power supply wattage rating.
Voltage (see the safety 90 to 135 V and 180 to 265 V at 50/60 Hz
instructions in the Product
Information Guide for important
voltage setting information)
Backup battery 3-V CR2032 lithium coin cell
And I have no idea what most of this means. If I'm reading it correctly, I have three PCIe buses, with different speeds. I don't know what the speeds mean, but I suppose I want to plug a new VC into the x16? As for the PSU, I have no idea if 375 W is good or bad.
If someone would like to help me interpret all this and tell me if there is anything else I need to know, I would be very grateful.
Oh, and I currently have an nVidia GeForce 7900 GS.

I've looked around a bit, and am now trying to decide between the following:
It's mostly in swedish, I've translated some of it, the rest should be either self-explanatory or uninteresting. "Ja" is Yes, "Nej" is No and "Ingen information" is N/A. If there's anything else, please don't hesitate to ask.
As of 2009-03-13, the exchange rate from swedish Kronor to U.S. Dollars is 100 Kr to 11.38 $.
