Pci-e 2.0
« on: December 06, 2007, 11:20:39 PM »
Sorry to ask such a dumb question, but I was looking at this video card:

http://www.newegg.com/Product/Product.aspx?Item=N82E16814102715

I was wondering if this PCI-E 2.0 interface card will work OK in an Asus P5k mobo with a PCI-E x16 slot, or does it require a different mobo with a 2.0 slot?


Thanks!

PCI turns 2.0

But it doesn't say if you need a special motherboard or if the standard x16 PCIe slot will work :huh

System Requirements:

* PCI Express based PC is required with one X16 lane graphic slot available on the motherboard.
* 1GB or greater system memory for better performance.
* 450Watt or greater power supply with 75 Watt 6-pin PCI Express power connector recommended.
* For ATI CrossfireX: 550 watt power supply or greater with two 6-pin connectors.
* Certified power supplies are recommended.  Refer to http://ati.amd.com/certifiedPSU for a list of Certified products
* Installation software requires CD-ROM drive.
* DVD playback requires DVD driver
* Blu-ray/HD DVD playback requires Blu-ray/HD-DVD drive and playback software.
* For a complete ATI CrossFireX™ system, a second ATI Radeon™ HD 3850 graphics card, an ATI CrossFireX Ready motherboard and one ATI CrossFireX Bridge Interconnect cable per board are required.

Just a couple of days ago there were no 3000-series on newegg. Based on reviews and price, it's on my new wishlist (my hypothetical wishlist, hamstrung by a lack of money :D )

Building a new PC myself so I have been researching this out.

PCIe 2.0 is backwards and forwards compatable.  That means the following:

PCIe x16 Card/PCIe 2.0 Slot = Compatable
PCIe 2.0 Card/PCIe x16 Slot = Compatable

Do you know if they'll work in a PCIe slot that's running at (I think) 4x?

I've got a dual board, AGP/PCIe, but the PCIe really runs at 4x (8x??) instead of 16x. There's little performance loss according to benchmarks, so I'm not worried with it, as-is.

However, it would be nice to know if I have to upgrade to get an ATI 3850, or if I can stick one in (hypothetically) and upgrade the mobo later.

The 3850 looks like a good card. Just out of curiosity, do you guys know how much improvement in video performance there is if you have two of these cards in Crossfire mode?

Very much so! Has allowed me not only to upgrade to PCIe, DDR2, but also to a conroe! I had an AGP, DDR1, and 533MHz fsb Pent4 previously. I've done it one piece at a time, and it's much easier!

Isn't there a physical size difference?

PCIe was forced on us by the market. CPUs still can't keep up with a full-speed AGP card, that's why you see little difference.

No, no size difference. It's a 16x slot, but it's real rating is 4x (or 8x, can't recall) because it's supporting both AGP and PCIe... Some technical reason.

Anyways, it takes standard PCIe cards (like my current one) but ranked with a full 16x slot it's less than 10% slower on benchmarks. I did some checking before I bought it to make sure I wasn't gimping myself.

I just didn't know if that would gimp a PCIe 2.0 card or not.
