What is unbuffered RAM ?
357624
Buffered/Registered means built in error checking, and some CPUs need that (typically high end ones)\n\nUn-buffered/registered means that it doesn't do this, average PCs require this kind and is cheaper

Look up your system model on the support section of the manufacturer's page.  There will be a lot of technical jargon in the RAM section that you will probably not understand.  Copy it down and take it to a store that sells computer accessories (Best Buy, Circuit City, CompUSA, etc) and show it to the salesman.  If you want really good performance, tell him you want low-latency RAM instead of the budget high density crap.  Until then, increase the size of your paging file and hope for the best.  You can also disable unnecessary startup entries and background services.  Many people will tell you to use msconfig by going to Start - Run, typing "msconfig" then go to startup tab, this is not quite accurate.  To accurately disable the startup you should disable it from within the settings of the program itself.  This is to be sure that the registry entry is not recreated on the next reboot.  To disable background services that you don't need, go to Start - Run and type services.msc.  Disabling unnecessary services here will free up a lot of resources - probably more than anything else you could do to the system minus upgrade.  Also, you should optimize your caches.  If you can perform these tweaks effectively, you may not even need a RAM upgrade, but it's still recommended if you have less than 512MB RAM in XP.

RAM (Random Access Memory) is volatile so all that is needed to "clean" it is to restart your computer.  Volatile means that its contents are not persisted across multiple restarts of the computer.\n\nThat being said, if you keep your computer running long periods of time, memory can be "leaked" from applications such that overall performance of your computer can degrade.  Without rebooting, this will slowly (or not so slowly) cause performance issues.\n\nYou can purchase software the will periodically optimize memory.  Once such tool is called RAM Idle LE 1.5.  Do a Google search to find out more if you like.\n\nColby

Well, if 'dodgy' just means poor quality, it can't make your computer quite as fast as the same quantity of high-quality ram would. If you mean nonworking, though...\n\nBlue screening, primarily right in the middle of a program. Also can cause 'insufficient memory' messages, even when you don't have many resource-consuming programs running. Not to mention overall slow preformance.

Imagine a block of memory from 0 to N. A cyclic buffer fills from 0 towards N, and when it reaches N it starts back at 0 again.\nThis kind of buffer needs to be "serviced" (have the data removed) before new data overwrites data that hasn't been removed yet.\nThere is normally an "in" pointer for incoming data, and an "out" pointer for outgoing data, If the "out" pointer reaches the "in" pointer, the buffer is empty again. If the "in" pointer reaches the "out" pointer, you've overflowed the cyclic buffer!

Can't answer the first question.\n\nThe native state of computer memory is null. That is not the same as blank or zero; it's nothing.

haha i hear for the first time about sodium ram... what i know abt RAM types are:\n\nKinds of RAM\nRAM can be divided into (1) main RAM, which stores every kind of data and makes it quickly accessible to a microprocessor and (2) video RAM, which stores data intended for your display screen, enabling images to get to your display faster. \nMain RAM\nMain RAM can be divided into static RAM (SRAM) and dynamic RAM (DRAM). \n\nStatic RAM (SRAM)\nStatic RAM is more expensive, requires four times the amount of space for a given amount of data than dynamic RAM, but, unlike dynamic RAM, does not need to be power-refreshed and is therefore faster to access. One source gives a typical access time as 25 nanoseconds in contrast to a typical access time of 60 nanoseconds for dynamic RAM. (More recent advances in dynamic RAM have improved access time.) Static RAM is used mainly for the level-1 and level-2 caches that the microprocessor looks in first before looking in dynamic RAM. \nBurst (or SynchBurst) Static RAM (BSRAM)\nBurst SRAM (also known as SynchBurst SRAM) is synchronized with the system clock or, in some cases, the cache bus clock. This allows it be more easily synchronized with any device that accesses it and reduces access waiting time. It is used as the external level-2 cache memory for the Pentium II microprocessor chipset. \nDynamic RAM (DRAM)\nDynamic RAM uses a kind of capacitor that needs frequent power refreshing to retain its charge. Because reading a DRAM discharges its contents, a power refresh is required after each read. Apart from reading, just to maintain the charge that holds its content in place, DRAM must be refreshed about every 15 microseconds. DRAM is the least expensive kind of RAM. \nFast Page Mode DRAM (FPM DRAM)\nPrior to newer forms of DRAM, Fast Page Mode DRAM (FPM DRAM) was the most common kind of DRAM in personal computers. Page mode DRAM essentially accesses a row of RAM without having to continually respecify the row. A row access strobe (RAS) signal is held active while the column access strobe (CAS) signal changes to read a sequence of contiguous cells. This reduces access time and lowers power requirements. Clock timings for FPM DRAM are typically 6-3-3-3 (meaning 3 clock cycles for access setup, and 3 clock cycles for the first and each of three successive accesses based on the initial setup). \nEnhanced DRAM\nEnhanced DRAM (EDRAM) is the combination of SRAM and DRAM in a single package that is usually used for a level-2 cache. Typically, 256 bytes of static RAM is included along with the dynamic RAM. Data is read first from the faster (typically 15 nanoseconds) SRAM and if it is not found there, it is read from the DRAM, typically at 35 nanoseconds. \nExtended Data Output RAM or DRAM (EDO RAM or EDO DRAM)\nExtended Data Output RAM (EDO RAM) or Extended Data Output Dynamic RAM (EDO DRAM) is up to 25% faster than standard DRAM and reduces the need for level-2 cache memory. \nBurst Extended Data Output DRAM (BEDO DRAM)\nBEDO DRAM improves page mode DRAM by "building in" three successive column address shifts after the first column address is specified so that four bits are read as a burst. Together with a dual-bank architecture, BEDO DRAM promised to offer 4-1-1-1 access times. However, because Intel and other manufacturers preferred SDRAM, BEDO DRAM was not widely used. \nNonvolatile RAM (NVRAM)\nNonvolatile RAM (NVRAM) is a special kind of RAM that retains data when the computer is turned off or there is a power failure. Like the computer's read-only memory (ROM), it is powered by a battery within the computer. It can also work by writing its contents to and restoring them from an EEPROM. \nSynchronous DRAM (SDRAM)\nSynchronous DRAM (SDRAM) is a generic name for various kinds of DRAM that are synchronized with the clock speed that the microprocessor is optimized for. This tends to increase the number of instructions that the processor can perform in a given time. The speed of SDRAM

In computing, buffer underrun or buffer underflow is a state occurring when a buffer used to communicate between two devices or processes is fed with data at a lower speed than the data is being read from it. This requires the program or device reading from the buffer to pause its processing while the buffer refills. This can cause undesired and sometimes serious side effects, since the data being buffered is generally not suited to stop-start access of this kind.\n\nBuffer underruns can cause serious problems during CD/DVD burning, because once the laser is on, it cannot stop and resume flawlessly; thus the pause necessitated by the underrun can cause the data on the disc to become invalid, and thus unusable. Since the buffer is generally being filled from a relatively slow source, such as a hard disk or another CD/DVD, a heavy CPU or memory load from other concurrent tasks can easily exhaust the capacity of a small buffer. Therefore, a technique called buffer underrun protection was implemented by various individual CD/DVD writer vendors, under various trademarks, such as Plextor BurnProof and Yamaha SafeBurn. With this technique, the laser is indeed able to stop writing for any amount of time and resume when the buffer is full again. The gap between successive writes is extremely small.
