RAM

Hi,, i'm going to buy a new PC.. but my knowledge in hardware is limited.. I want to ask about types of RAM (SD , DD) also types of slots (AGP , others) I read advertisments..But i can't compere it :confused:
I am not a pro, but may be I could give you some advice. 1. RAM: RDRAM are the fastest (as far as I know), but the most costy. I'd prefer DDR SDRAM (double data rate SDRAM), as they are fast and cheap (relatively). SDRAM (synchronous dynamic RAM) is was the cheapest, but still the oldest. I haven't read in that field lately, but the speeds I know are: RDRAM: 800, DDR SDRAM*: 266,333,400, SDRAM: 133. * DDR SDRAM work on double the speeds listed here, so when I say 266 that means that it actually works at 533. 2. Processor: Make sure you have enough cache. It can really affect the performance of the whole computer. If I can buy a 1 GHz with 512 KB cache or another 2 GHz with 128 caches I would buy the 1 GHz. 3. Slots: Unless you will settle for a built-in graphics card, you will need to have an AGP slot. As far as I know, all motherboards without a built-in card have these slots. Some people are short of money, so they buy a motherboard with built-in graphics on the hope that they will buy a card later. If you intend to do so, make sure the motherboard you get contains an AGP slot (some of them do not). Time is running, and that's all I can write about now. But, you can find much more information at the following link: ExtremeTech Build It[^] Everybody: I know I may be wrong at some things, so please correct me.

I'm not completely sure but I was under the impression that 266 was the double speed (of 133 SDRAM). Can anybody confirm? Other than that, this is exactly what I'd be looking for when building (or buying) a new computer.:) Brad Jennings I like pancakes!

I second what Hosam Aly Mahmoud says. Also, if you're a PC gamer, you might want to look into getting something with an 8x AGP port for your graphics card. Have fun with your new system.:) Brad Jennings I like pancakes!

I think you are right. According to ExtremeTech:[^] Double Data Rate (DDR) SDRAM is essentially the same thing as SDR SDRAM, except that it can output data on both the rising and falling edges of the clock signal. The standards for DDR SDRAM are known as PC1600 (200MHz data rate and 100 MHz clock) and PC2100 (266MHz data rate and 133MHz clock). Those guys at ExtremeTech[^] do have good articles! Especially the Build It[^] section.

RDRAM has higher burst figures, but because of setup times its performance isn't much better than DDR in practice. Elaine :rose: The tigress is here :-D

Thank you all for information.. Hosam Aly Mahmoud wrote: Processor: Make sure you have enough cache I was planning to get a celeron 2GB with 128KB cache..I think this will be bad from your point of view. I'll buy a Main board with built in Graphics card.. do you think MSI is a good choice ? do you recommend a specific shop in Egypt(cairo) with good prices and support,Hosam ? what do you think about the (Computer in every home) project?

Since you are asking country-specific questions, I prefer to answer this one by e-mail. I sent you an e-mail with my address, so send me one with yours.
