Memory timing examples[edit] Memory timing examples (CAS latency only) See External links section below for a Google Sheet where you can enter the Type and CAS to compare several sets of What a difference an upgrade can make. http://divxeo.com/difference-between/difference-between-sdram-and-ddr-ram.html

Each chip is divided internally into eight banks of 227=128 Mibits, each of which composes a separate DRAM array. Each bit line is connected to a sense amplifier that amplifies the small voltage change produced by the storage capacitor. Fortunately, the processor typically does not need to wait for all eight words; the burst is usually sent in critical word first order, and the first critical word can be used Text is available under the Creative Commons Attribution-ShareAlike License; additional terms may apply. https://forums.anandtech.com/threads/whats-the-difference-between-cas-latency-2-2-5-and-3.1342843/

Anything else, introduces a slight speed hit. The best practice in the field is constantly changing and unique quality requirements and management issues are regularly emerging. Ask ! Because the latency is dependent upon a number of clock ticks instead of absolute time, the actual time for an SDRAM module to respond to a CAS event might vary between

In general the lower the CAS latency the better within a given memory technology (DDR, DDR2or DDR3).

The CAS latency is the delay between the time at which the column address and the column address strobe signal are presented to the memory module and the time at which http://divxeo.com/difference-between/difference-between-these-two-hd-7770s.html Still a unit of time, but a variable unit of time depending on clock frequency.Mike. With Intel I'd still get PC2700 CL2.0 as anything over this is unlikely to have truely been individually certified to run higher and simply won't be worth the price premium.

A modern microprocessor might have a cache line size of 64 bytes, requiring eight transfers from a 64-bit-wide (eight bytes) memory to fill. weblink I also read the following article on Tomshardware (http://www6.tomshardware.com/motherboard/20040119/index.html).

Accordingly, the CAS latency of an SDRAM memory module is specified in clock ticks instead of absolute time. The CAS latency can only accurately measure the time to transfer the first word of memory; the time to transfer all eight words depends on the data transfer rate as well. When no word line is active, the array is idle and the bit lines are held in a precharged state, with a voltage halfway between high and low. http://divxeo.com/difference-between/difference-between-math.html Skip to content CPUs GRAPHICS MOTHERBOARDS CASES & POWER STORAGE MOBILE GAMING FORUMS JOBS MORE...
