I did a test of 16 separate users running, GIMP, Eclipse and several other aplications on the same system. While 32bit systems can address up to 16GB or RAM using PAE, system libraries and applications take less space in memory compared to 64bit systems. I’d like to share some things from my experience and observations on Linux.ġ) Use 32bit OS and software. Nice guide to purchasing a PC for using with DisplayLink. Feel free to comment if you have any questions. In terms of particular CPUs, that maps out to Intel CPUs like the the Core i3 530 or higher for the desktop, and the Core i3 330M or higher for laptops. The sweet spot currently is with DDR3-1066 memory interface or better and at least 3 MB 元 cache. Products change quickly, but currently Intel’s “Nehalem” microarchitecture provides the best alternatives. So what to look for in the CPU’s memory controller? Faster memory interface and larger caches. that work is all done by the hardware framebuffer on the USB device, so in terms of CPU load, it’s just about the pixels that are changing at any given moment. Note that once the changed pixels are sent over USB, the CPU isn’t involved anymore to refresh the display. In the USB graphics case, memory and the memory controller is getting a lot of use, as pixels change on the screen (at least 4 times – when an application renders new pixels, when those pixels are composited on the desktop, when they’re copied to a shadow framebuffer, and when those changed pixels are compressed into USB packets). Even though Windows 7 is much improved over Vista, multiple monitors and many open applications still consume a lot of memory.īut just as important as the amount of RAM is the amount of cache. although going to 4 or more will produce noticeable overall system gains (mostly because of all the additional apps you’ll be running to display on all those monitors). But no need to go overboard – there’s usually a sweet spot.įor memory with Windows 7 and something like 6 USB displays, 2GB is enough. Take the money saved on a high-end 3D processor, and funnel it back into the main CPU and memory that’ll make everything on your PC faster. Second, for the system itself, more memory and a faster CPU make a difference. But as it happens the simplest and lowest cost solution is also the best choice for this particular application. NVidia and ATI/AMD are great companies that produce high-performance products, and DisplayLink’s software rarely have problems with them. For business applications (like stock trading) with many displays, it makes sense to favor simplicity and compatibility over 3D gaming performance.
