No. YOU MUST REMOVE the DDR adapter from RAMCHECK in order to test the 168-pin SDRAM (or EDO/FPM) modules. DDR and SDRAM use different voltages, and the DDR adapter further loads the SDRAM test bus. To avoid flexing damage to the DDR adapter, please allow the DDR adapter to cool down prior to removing it from RAMCHECK, and carefully remove using two hands .

Synchronous DRAM technology emerged in the mid nineties and provided a revolutionary change in the way DRAM interfaced to a computer. It synchronizes all the read/write transfers to a system clock, thus providing significantly faster transfer rate for contiguous (same Row Address) group of data. A Synchronous DRAM can burst up to a full columns length of continuous data at the device clock rate (currently 150Mhz and higher rates).

DDR SDRAM is a straightforward evolution from current single data rate (SDR) SDRAM. DDR, which stands for Double Data Rate SDRAM, actually doubles the bandwidth available to your system and runs twice as fast as regular SDRAM. For example, 266MHz DDR SDRAM (133MHz doubled) has the bandwidth of 2.1GB/sec and is referred to as PC2100. The big difference between DDR SDRAM and standard SDRAM is that DDR reads data on both the rising and falling edges of the clock signal.

SDRAM (single dynamic randomn access memory) is the older style of memory with 2 notches on the stick. The speed of SDRAM is either 100 or 133 MHz (older SDRAM was 66 MHZ - do not mix with pc133 memory !) DDR (double dynamic rate) memory has only 1 notch. The DDR memory will read twice (double) as much information as the SDRAM - the speed of DDR is from 266 to 400 MHz

No. Even though there are systems that support both technologies, you can't have DDR and SDRAM in the same system at the same time. You'll have to choose one or the other.

No, you cannot mix them. DDR DIMMs only work if you have a DDR-enabled system. DDR will not work in an existing SDR SDRAM system, or vice versa.

Yes. DDR transfers data twice as fast as SDR SDRAM modules. This doesn't necessarily mean your system will run twice as fast, but your memory will. And faster memory will improve your computer's performance.

Yes. RAMCHECK's optional DDR 184-pin Adapter (p/n INN-8668-6) supports modern 184-pin DIMM DDR modules and is at the heart of our new DDR Series. A low-cost converter (p/n INN-8668-6-1) supports 200-pin S.O. DIMM DDR modules. Due to the importance of DDR technology, we have introduced the RAMCHECK PLUS bundle, a combination package of RAMCHECK and the DDR adapter.

PC100 SDRAM is required for CPUs (such as the AMD K6-2/350) that runs at 100MHz front side bus speed.

Synchronous DRAM technology provides a revolutionary change in the way DRAM interfaces to a computer. It synchronizes all the read/write transfers to a system clock, thus providing significantly faster transfer rate for contiguous (same Row Address) group of data. A Synchronous DRAM can burst up to a full columns length of continuous data at the device clock rate (currently 100Mhz and higher rates). Both the SIMCHECK II and SIMCHECK II se RAM testers support our new Sync DIMMCHECK 168.

PC SDRAM is a loose general term for SDRAM that runs at 66 MHz and has an SPD chip for compatibility with P-II motherboards. PC100 SDRAM refers to PC100 SDRAM chips or DIMMs that meet INTL PC100 qualification standard. These parts are designed to run at 100 Mhz front side bus (FSB) speeds. Registered SDRAM - This is SDRAM module with Register for Address and Control Signals.

Each time a module is installed on your system, it appends information like the following to a file called perllocal.pod which can be found in /usr/local/lib/perl5/version number/architecture/ or something akin to that. The path for your specific installation is in your @INC which you can divine with perl -V. =head2 Wed May 12 13:42:53 1999: C<Module> L<Data::Dumper> =over 4 =item * C<installed into: /usr/local/lib/perl5/5.

The financial modules, including General Ledger, Purchasing, Accounts Payable, and Grants will be installed first.

No, you can't. DDR memory is not backwards compatible. And you most likely can't use EDO. The bx chipset indeed has support for EDO memory, but most boards don't (an exception to that are the bx based boards from supermicro). If you really happen to have a board which has support for EDO modules (check your manual) you can't mix EDO rams with PC66/100/133 sdrams, and you can only run at 66mhz FSB (that is, you'd have to use a P2 up to 333mhz or a Celeron up to 766mhz).

No, DDR2 DIMM memory modules are not backwards compatible with DDR DIMM, due to incompatible pin configurations, core voltage, and memory chip technology. DDR2 modules are designed with a different "key" in the edge connector to prevent insertion into incompatible memory sockets such as DDR motherboard. A DDR2 SDRAM DIMM will not fit into a standard SDRAM DIMM socket or a DDR DIMM socket. DDR2 modules use a 1.8V power supply, providing a big power saving over the 2.5V DDR modules.

Yes. A module's size in megabytes is usually referred to as its "density." You can use DDR modules of different densities in the same system. For example, you can use one 32MB module, one 64MB module, and one 128MB module. To find the total memory in a system, add together the memory of each module. In the example above, your total memory is 32MB + 64MB + 128MB = 224MB. The reason for the hard drive activity is limited memory.

Yes. JDI provides a library application for performing testing on SDRAM and DDR2 SDRAM. These are available as working projects with application notes, and are included in the price of the purchase of the system at no additional cost.

Yes. RAMCHECK has a much higher range than our previous SIMCHECK II technology and it supports older SDRAM modules running at 66MHz or 100MHz, as well as the state-of-the art faster modules. Yes, RAMCHECK identifies this module by displaying "SPD=CL2 at 100MHz" in the last summary screen as well as in the Test Log. .

Day Delegate Rate. This is the cost per person in hiring the conference room. Day Delegate Rates normally come as a package typically including room hire, teas/coffees and lunch. DDR packages will vary from operator to operator and package to package.
