Display problems
Some time ago I wrote a post about the problems that have arisen with my old desktop PC. I doubt that you’d remember, but the two problems is question were the wrong RAM modules and the strange lines running through the screen.
These problems render the rig completely useless, and I have just figured out, that if I wish to use it as I prefer (that is with a Full HD 1920×1080 resolution), big changes will have to be made to the configuration.
I discussed the original matter with my godfather, who’s pretty much a pro in terms of computing, and he told me, that the image visible on the screen is also stored in the memory, and that the lines might be due to the slow speed of memory access.
Well I just calculated the required speed, and guess what? He was right. The display image (assuming 32 bits per pixel) needs around 8MB of RAM. To read that out of the memory 60 times per second (because of the 60Hz refresh rate), a RAM access speed of approximately 475MHz is required, whereas my config is only capable of 333MHz.
So the conclusion is that I’ll have to upgrade my computer significantly. Hopefully to some sort of multi-core processor and at least a few gigabytes of DDR2 RAM. Unfortunately those kinds of boards come with SATA and PCI-E ports, therefore the harddrive and the graphics card will need to be changed too. And that’s a lot of money…

I like your feed but you should post more
I really am trying to find time to write, but it’s not going to be soon enough (even for me). To be honest, I tried a while ago to post pretty much about everything that comes into my mind, but I quickly found that it was not what I wanted to do.
