Wanting to findout what kinda ram i need to get for an upgrade. this computer only has 256mb.
SDRAM
(Synchronous DRAM)
Almost all systems used to ship with 3.3 volt, 168-pin
SDRAM DIMMs.
SDRAM is not an extension of older EDO DRAM but a new type
of DRAM
altogether. SDRAM started out running at 66 MHz, while older
fast
page mode DRAM and EDO max out at 50 MHz. SDRAM is able to
scale to
133 MHz (PC133) officially, and unofficially up to 180MHz or
higher.
As processors get faster, new generations of memory such as
DDR and
RDRAM are required to get proper performance.
DDR
(Double Data Rate SDRAM)
DDR basically doubles the rate of data transfer of
standard SDRAM
by transferring data on the up and down tick of a clock
cycle. DDR
memory operating at 333MHz actually operates at 166MHz * 2
(aka
PC333 / PC2700) or 133MHz*2 (PC266 / PC2100). DDR is a 2.5
volt
technology that uses 184 pins in its DIMMs. It is
incompatible with
SDRAM physically, but uses a similar parallel bus, making it
easier
to implement than RDRAM, which is a different technology.
hi, thanks for your reply, so what would be my total speed?? 128+256= 384 minus the shared memory?? I'm sorry didn't get what you mean by "it always runs on the slowest speed. Do you mean the 266 Mhz processing speed?? Thanks...
