This limitation does not apply to Windows and Windows XP. Windows 9. Most home users of Windows 9. Windows 95, 98, and Me are based on Windows 95 architecture. There is a configuration file fix that can be applied to make Windows 98 function with as much RAM as you are likely to throw at it. Microsoft has a tendency to change the links to KB articles, so if a link fails to work enter the article's Q number in the search box on the following page.
As you can determine from the information in the link itself, the Microsoft link above leads to the article with the Q number of Q Memory-card readers.
If you use several different kinds of devices that use their own kinds of memory cards, you can purchase memory-card readers that can read the different cards.
You could spend a long time transferring files from the devices to a desktop computer by using, say, USB cables. But if you buy an inexpensive memory-card reader, you can eliminate the need to plug and unplug lots of different USB cables. The 6-in-1 Media Reader requires a 3. You can copy the contents of one type of card to the desktop computer's hard drive, insert a different card, and copy the contents to it, or you can just copy the contents to the hard drive.
The USB 2. It also has a USB 1. Motherboard and BIOS settings. For images of and information on the jumpers and DIP switches used on motherboards to enable various functions, visit the Motherboard page of this site.
There are also several other pages devoted to RAM on this site. Unfortunately, the ability of Windows to use RAM does not always coincide with ability of a motherboard's chipset to cache RAM, so be sure to check your motherboard's manual before you upgrade.
The motherboard's chipset determines how much RAM can be cached. If the motherboard has an elderly chipset, the amount of RAM it can cache might be limited to as little as 64MB.
If a motherboard can only cache 64MB of RAM, such as one with the elderly Intel TX chipset, and you install MB, even if it works, it will slow the system down significantly, because the excess RAM cannot be cached, and so will be accessed in the same relatively slow manner as the virtual memory swap file that Windows sets up on the hard disk drive is accessed.
The moral of the story - if you have an ageing PC, always find out how much RAM your motherboard can cache before upgrading. RAM of poor quality will isn't worth any savings you can make, because it can be the source of all kinds of system failures.
How to identify the size of RAM modules. You have purchased a large collection of RAM modules - SIMMs and DIMMs - that you want to resell, but you have no idea of how to identify the memory capacity in megabytes MB of the individual modules, and you want to know if there is any way to determine the size of a module other than by installing it on a motherboard in a computer that supports that type of RAM. It is possible to identify the chips by part number. You have to identify the size of each the chips on a module, and then multiply the size by the number of chips on the module to determine its memory capacity.
Different RAM manufacturers have developed their own methods of identification, so it is has become difficult to identify the chips without looking up the exact part number on a website that provides the information. Luckily, the Internet has made doing this fairly easy via the Google search engine. Unless they have been remarked by unscrupulous dealers that are selling substandard modules not passed for use in a computer as computer-quality, all of the chips on a particular module will have the manufacturer's name or logo , and a part number printed on them.
You should be provided with links to many sites that provide information about part numbers. The KM indicates parts made by Samsung. The 41 indicates that it is a 1Mbit x 4 part. This means that the chip holds 4Mbits. Eight of the nine chips hold memory, so this is a 8 x 4Mbit, or 32Mbit module. There are eight bits to a byte, therefore this is an 4MB module. The ninth chip is there to add parity. This was used as a means of checking for memory errors that is no longer used.
The 12 in the part number indicates that the module has a maximum frequency speed of 66MHz. By: Kaushik Pal Contributor. By: Leah Zitter Contributor. Dictionary Dictionary Term of the Day. Techopedia Terms. Connect with us. The specifications will be listed in the motherboard's manual.
Windows 98 can itself use as much RAM as any current motherboard. Not being able to cache more than that amount of RAM means that it takes its time accessing it. Windows 95 versions OSR 2. Intel Pentium 4 processors. SDRAM modules do not have to be installed in pairs ; single modules will function. Not only do you have to purchase a dedicated motherboard for a Pentium 4, you also have to purchase a dedicated case to house it.
A special power supply unit with extra power lines is required, and the case has to have extra stand-off points to support the motherboard. Another good reason to buy AMD. You can use a standard ATX case to house the motherboards that support all of its processors. The FSB is the network of interconnections between the various parts of the motherboard.
A Socket A motherboard must specifically support it. Motherboards with this capability are available from most of the major motherboard manufacturers. It was named PC because it has a data bandwidth of 2. Still confused about the different types of RAM? It is very easy to become confused with the different types of RAM that will or will not run on the different types of motherboards that support Intel or AMD processors.
Start by remembering that motherboards that support Intel processors never support AMD processors, and you are half way towards clearing up the confusion.
The motherboard must support a given processor if you are to use it. It is then just an simple matter of consulting the motherboard's manual to find out the types of RAM and the processors that it supports. You can download the manuals from the websites of most of the major motherboard manufacturers.
As long as you only install items on a motherboard certified by its manual to run on or with it, you cannot go very far wrong. Most systems that have motherboards that use SIMM memory modules require you to use matching pairs of modules to fill a bank of slots on your motherboard. If you fail to match them correctly, your system will probably not function properly. Therefore, always check your system and motherboard manuals before you place an order.
Modern motherboards are also often much more forgiving about which DIMM modules that can be fitted - they do not all have to be of the same capacity. Remember, never skimp on quality when it comes to RAM. Even when buying a new PC always obtain a system specification and check what make of RAM is installed.
Only grade-A memory will do, and it is only manufactured by the major manufacturers of RAM. RAM is probably the most critical system component.
It is a fact that many program crashes can be attributed to cheap, error-prone or defective RAM. If the vendor's advertisement, or system specification does not name the manufacturer, then it is usually generic RAM that is on offer, much of which is not likely to be grade A RAM. The problem. You want to run an AMD Duron 1. Even though the processor has a maximum speed frequency of 1. The FSB speed is the speed with which the processor is able to communicate with the rest of the system.
It can do its own calculations at 1. But with DDR RAM installed, the processor's effective data transfer speed would be responsible for creating the bottleneck. So, in this case, the processor is creating the bottleneck by having an effective data transfer rate that is MHz slower than the RAM. Pluto Senior member. Jan 15, 0 0. Dec 16, 4, 0 0. In pairs. MadRat Lifer. Oct 14, 11, 50 Eeek, just imagine your upgrade in memory.
Feb 1, 1, 0 0. Rand Lifer. Oct 11, 11, 1 Depends on thechipset, RAMBUS natively doesnt depend upon being installed in pairs but certain chipsets such as the I and I require them to be installed in pairs.
