ATI, the graphics division of Advanced Micro Devices aggressively dismissed the rumors alleging the fact that its graphics cards do not and will not have compatibility issues with older platforms. While Nvidia's
GeForce 8800 graphics cards experienced some problems on the old platforms, the ATI Radeon HD 3000-series of graphics cards did not encounter any problems.
Last year, Taiwanese PC manufacturer and vendor Asustek Computer claimed that some of the Canadian company's PCI Express 2.0 graphics cards may experience compatibility problems when seated on motherboards that only support PCI Express 1.0a and 1.1 2.5GHz transfer rates.
On the other side on the fence, many of Nvidia's GeForce 8800 GT-based graphics cards that come with PCI-Express 2.0 support, could not correctly work on Intel 925 chipset-based systems, although they should have been backwards compatible.
"There were potentially compatibility issues with PCI Express 2.0 graphics cards and certain PCIe 1.0/1.1 platforms. We asked Asustek to double check if there were any issues with ATI Radeon HD 3800-series as we believed there shouldn't be. Asustek carried out that test and verified that, indeed, ATI Radeon HD3000-series cards do work with no compatibility issues," said David Baumann, a technical marketing manager at AMD's graphics product group.
AMD spokespersons claimed that the ATI Radeon HD 3000-series initially starts up as a PCI-Express 1.0 device, and then "expands" to higher modes if they are supported by the host motherboard. "This way ensures that there shouldn't be any compatibility issues with pre-PCIe 2.0 platforms," Baumann added. Further tests did not reveal any compatibility issues in the Radeon HD 2000 and HD 3000-series running on PCI-Express 1.0 or 1.1 motherboards.

| Comment #1 by: Mark on 26 Jan 2008, 12:36 GMT |  reply to this comment | Why would anyone want to install a PCI 2.0 graphics card in a PCI 1 PC anyway? Might as well go with a cheaper card. |
| Comment #2 by: satyr on 27 Jan 2008, 09:51 GMT | reply to this comment | Because manufacturers have long since stopped production of PCI-Express 1.0 / 1.1 cards, but not all of the users upgraded their old motherboards to the last PCI-E 2.0 standard. Cheaper 1.0 / 1.1 graphics adapters are becoming harder and harder to find. |

PCIe 1.x motherboards are still in production and on store shelves. We are still in the midst of the transition. |
| Comment #4 by: Tri on 25 Feb 2008, 04:57 GMT | reply to this comment | Because like me, I want to play new games like NFS pro street. But after I try with my VGA card (ati1650pro 256mb), it just can't play with good resolution and fps. (800x600, low detail, 18-24fps). My MB is Asus A8RMVP (I bought it at April 2006)(PCI Exp1.0). So now, I'm have plan to buy new VGA card like ati x3850, or maybe GF9600. |
| Comment #5 by: SWIN on 28 Feb 2008, 14:42 GMT | reply to this comment | The 8800GS GT / 9600 Nvidia have problems with VIA PT880 Ultra chipsets, as found in Asrock 4CoreDual-VSTA motherboards.
You have to reflash with another VGA Bios - if you can get one from your card vendor.
If not - you have to go to ATI - so Nvidia is really messing things up, as a 2.0 card dont boot up in some 1.0 / 1.1 only motherboards.

| Comment #6 by: cesar on 17 May 2008, 07:09 GMT | reply to this comment | if that so, how come i'm having trouble with my system. i just bought HIS ATI HD3870 and installed into MSI 975x platinum powerup edition mobo. During game crysis everything is set to "HIGH" while AA is turned "OFF", the game goes fine. Then turn the AA into "2x", play for a while then a "VPU recover error" will appear. If you guys have any solution, I would appreciate it "VERY MUCH".
Rest of the system is using : Thermaltake 850Watts, 2x1gbs Patriot 800mhz, 160 WD raptor, Intel Q6600. |
