Then, the display will turn red and stay red. RAMCHECK DDR3, DDR2 & DDR memory testers for all types of electronic memory devices, including SDRAM/EDO/FPM DIMMs and SIMM modules and memory chips. The attached schematic shows the original design of the memory module and how it's connected to the MPU of target system. The test core is useful primarily on FPGA/CPLD platforms. The test circuit provides a test clock signal to an SDRAM of the type having an internal clock input. I have built a memory test, which uses the SDRAM logic I use on my cores (including CPS). The Sync DIMMCHECK 144 adapter has a proprietary 133MHz SDRAM test engine with enough horsepower to fully and quickly test today's 133MHz SDRAM at actual clock speeds.
