All These Speeds are they useful?????

This is where you can ask questions and get and give help about hardware related issues. This Forum will be moderated by Taw with help from some other experts. So feel free to ask any questions you may have about computers.

All These Speeds are they useful?????

I'm under 15(for lack of closer age for security) and I am self teaching myself about PC I under stand most hardware types but i want to know if bus speeds etc are Important in buying cumputers etc. I would also like to know the diferences between SD, DDR, DDR2 etc RAM.

(PS This is all performance-wise).

Dammit, and there goes our ability to work out whom you are from the 5 billion people on earth - there goes the potential to mug you for your lunch money when term starts again... drat!

bus speeds are good,but architectural improvements in the complete system are where its really at - engineers are constantly working on ways to eliminate bottlenecks that reduce the apparent performance of peripherals - ex. if you buy a new mobo that can take 1X fast cpu and 1X fast memory but the memory controller is only allowing .5X throughput you are wasting money buying an inferior mobo that can't get the best performance from your peripheral hardware;memory,gfx card,hard drives.

go AMD - they use proven technology with more emphasis on good architecture and improved bandwidth and less on impressive numbers like intel. the thing about bandwidth vs speed is that increasing speed just creates more heat and makes for a bus cycle with less margin for error, whereas increasing the bus bandwidths reduces bottlenecks and gives more throughput with better reliability. ask anybody who's familiar with intel & amd; cost, reliability, and performance wise AMD almost always wins.

I have a AMD (5 years old and with only 757Mh of proccesing power).

what CV said.

with a 700mhz+ AMD (Duron?) your main problem is getting compatible hardware, and you'll be stung in shops for kit of that spec, you'll prob have to use eBay. Actually the best thing to do is start from scratch, as to get any sort of decent setup you'll need a new m/b, processor, memory, video card, and prob a hard drive too. There's really nothing you can do with what you have now as most shops only stock whats currently in demand, and almost none of it will go with your kit.

your current setup prob uses SD-RAM PC-133 (synchronous dynamic random access memory) although some compatible motherboards like the KT-133 iirc did take the early DDR 266 modules as well (double-data-rate, but still synchronous dynamic random access memory) (DDR2 as you might begin to suspect by now is twice as fast)

yes bus speeds are important and as a rule of thumb the higher and faster the better, but fast memory in a slow motherboard is just a waste of money. And yes, CV is absolutely right, go down the AMD route, Intel haven't put out a decent processor since the Northwoods went out of production.

I'm not going to build my own PC any time soon (there is the £7 a week funding prob, but I did build this one ) I do use SD pc 133 RAM.

Can any-one give me a guide of speeds, eg 100-200 Mhz = 10 year old
1 Ghz= super
