I’m a little stumped by my most recent purchase.
Last week, I decided to fire up my Windows NT 4.0 experimental build, and the GeForce 6800 GS I previously used with it began to give a blue screen error. The blue screens continued even after I reinstalled the OS. In my frustration, I decided to buy a Radeon x600 in the hope I could get better stability and still maintain widescreen resolutions.
I bought this card. A number of websites report the part number (102A3343701) as a Radeon x600 XT with 256MB of DDR VRAM so I decided to order it for $10 shipped from eBay.
Now that I have it in hand and tested, I don’t think it’s an Radeon x600 XT. At the same time, I’m not entirely sure what it is.
It’s PCI ID matches the x600. Windows NT 4.0 can use the Dell drivers for the x600, but the driver reports it as an x300 PRO with 128MB of VRAM. The ATI drivers for Windows XP identify it as an x550 with 256MB of “HyperMemory”. The core clock and memory clock match the specs for both the x600 and x550.
So, do I have an x600 or an x550? It works with NT 4.0 either way, but I wish I knew what I had for sure.
