Unfortunately I'm not a hardware person so I couldn't tell you what the chipset and buss specs are...<< You can download the freebie app AIDA32 from the site below. Aida32 is, as the blurb says: "AIDA32 is a professional system information, diagnostics, and benchmarking program. It extracts details of all components of the PC and can display, print, or save it in various formats like HTML, CSV, or XML. For corporate users, it offers command-line switches, network audit and audit statistics, remote system information, and network management." Aida32 can create, among other formats, an HTML report of you system and what makes it tick. It will tell you more about your machine(s) than you ever knew, and of course it will give you the lowdown on what kind of CPU, CPU core, ram, ram type, chipset, graphics card...well, you get the idea. While Aida32's creator now has "a real job" and there is no more software development on it, this version is still recent enough to give you the info that you need to know about your machine. You can download a copy here: http://fileforum.betanews.com/detail/1033800563 Here's some mirror sites if the above link craps out on you (the two top links at the mirrors are dead, but others underneath are active): http://www.filemirrors.com/search.src?type=contains&file=aida32ee_393 Another great little freebie app is CPU-Z. If you ever read hardware reviews at places like Tom's Hardware, motherboards.org, etc., you've seen a screen grab of CPU-Z. While not as extensive as Aida32, CPU-Z will tell you what kind of CPU, ram, and motherboard chipset, you're running, among other things. You can download CPU-Z here: http://www.cpuid.com/cpuz.php I recommend using Aida32 so you can see what you buss speeds are as well. So download these and let us know what you're running. Enjoy.
