I have a question what is unbuffered memory its alot cheaper I just want to know what the diff is. and what I would have to do to it to make it work if anything. |

Registered memory contains registers or buffers that take care of signal distribution to all the DRAM on a DIMM. Because the buffers take one full clock cycle (2 DDR clock cycles) to buffer the control and address signals Registered memory has a higher latency than unbuffered memory. The tradeoff is that buffering increases the reliability of high-speed data access which is critical for server operations. As a general rule of thumb, Registered modules are only used in Servers and Mission Critical systems where reliability is crucial - this is particularly true in situations where a lot of large data is being moved. Regular home users and performance users will not get any benefits from Registered memory, and might actually see a slight decline due to the higher latency of the buffering. Just how much the performance is degraded is hard to say. Latency in general won't result in massive changes in performance - we're talking about single digit percentage influences in the lower range here (2-5%)... but honestly, if you are building a performance system even a 3% drop in performance is not going to be acceptable to you. |

it means that buffered memory is like a clean drain...all the water will go thru with ease, but unbuffered has a pretty good chance of becomming a little clogged, get it? so if you do important things, like run a server, dont get it, but if all you do is sit around looking for porn, then it will be worth it |

actually rx78... if you read what pred put in, buffered memory is slower... its like filtering the water before it comes out... to make sure you don't get any impurities. But the filtering takes time and therefore RUNS SLOWER. Unbuffered memory has no filter... does not become clogged... its like an open pipe going straight through. The advantage is speed. The disadvantage is you're more likely to get a hiccup when running applications. This disadvantage is negligible when running a personal computer or gaming pc. Actually using buffered would put unnecessary latency. So Ionflux, to answer your question, unless you're running a mission critical server, go for the unbuffered... its cheaper and faster. |
