| 125058 | 2003-03-02 09:46:00 | ok i know its dam fast and expensive but how fast and how expensive and do you need a special motherboard for it (or just a fast bus speed) I also found on pricespy a ram called RDRAM which runs upto 8 times faster (is this static) so i'm after Stats and Prices thanks alot |

| 125059 | 2003-03-02 09:57:00 | ummm static RAM. Never heard of it. You're not thinking of Solid State. Where they're planning on having RAM and HDDs using. |

| 125060 | 2003-03-02 10:01:00 | not to sur what to make of your post. mmmm.....mayby i should go get a cold one ;-) >static ram if you are referring to SDRAM then is slow and cheap. DDR SDRAM is more comman in new machines these days and is faster and not much more exspensive. RDRAM (rambus) is very fast and very expensive. not many motherboards need it. obviously you need the ram that fits whatever motherboard you have. |

| 125061 | 2003-03-02 10:01:00 | www.webopedia.com this has a BIT on Static Ram (SRAM) and www.webopedia.com is the best site for finding out computer lingo |

| 125062 | 2003-03-02 10:07:00 | Static RAM is very expensive and also very fast, since it doesn't need to be refreshed like DRAM has to be. Due to it's high costs I believe SRAM is used for memory CACHING, e.g. the L1 & L2 Cache on motherboards and built into CPUs. You only get a small amount of it because more than that and it'll cost too much for end users to buy. RDRAM is RAMBUS DRAM it's not static it's Dynamic hence DRAM (Dynamic Random Access Memory). Some reviews show that DDR RAM is (performance wise) better than RDRAM. You have to make do with DRAM since SRAM will not be available to you other than the small amount offered with memory caching. |

| 125063 | 2003-03-02 10:08:00 | i'm looking at buying a new motherboard and the faster the ram the better game server this comp will be Static RAM was the FIRST RAM ever made but very expensive it is still used in CPUs and GPUs in there chases |

| 125064 | 2003-03-02 10:11:00 | dam thats a bother thanks for that i didn't know they dont make it for RAM any more it would be dam fast though if i could get it i'll look at getting RDRAM is RDRAM faster than DDR? |

| 125065 | 2003-03-02 10:15:00 | There are two basic types of memory: Static and Dynamic. Dynamic (the D in RDRAM, SDRAM etc) which uses large numbers of capacitors to store the information. Because capacitors lose their charge over a period of time, the contents of the memory must be periodically refreshed. hence dynamic. This memory is cheap and easily produced. Static RAM (SRAM) is more complicated, working with a combination of logic cells arranged in a formation that creates memory. because each bit requires two or more logic cells to store, the RAM chip is large, requiring a large circuit board, and requires quite a bit of power to run. It is also harder to manufacture, making it more expensive. When speed is essential, Static RAM is far better, but 1MB of it is physically larger than a common stick of 128Mb SDRAM, so you definately wouldn't want to run your whole PC with it... If you have ever seen inside an older PC (386/486), there are several rows of small black chips, i think 16 pin jobs, on the motherboard. The whole lot of them combined is around 512Kb depending on the era of machine, and while the size can be reduced now, SRAM is still very large. Craig. |

| 125066 | 2003-03-02 10:27:00 | i doubt it would be used as cache cpu/gpu cache these days as the cpu/gpu has onboard cache not external (L1/L2). RDRAM is general more expencive. not to sure if its still the fastest as dual DDR is proberly faster. biggest thing is getting max speed for your $$$ in which case DDR is the best. don't get to worried about the ram as the motherboard is going to dictate what you use. |

| 125067 | 2003-03-02 10:32:00 | SRAM is used as the cache memory, but it is constructed on the processor itself. It still uses the same power-hungry, large (comparitively) logic cells. If you were able to get enough SRAM into a small enough package it would sweep the floor with the top DDR-RAM, but you would need a LOT of power and a LOT of space to house it.... | craig_b (2740) | ||
