Installation of 16GB modules requires all previous lower density modules to be removed. You cannot mix Registered and Unbuffered memory in the same system.
Memory or DRAM is the "working" memory of the computer. It's used to store data for programs (sequences of instructions) on a temporary basis.
Storage drives -- hard drives and solid state drives -- are the permanent memory for the programs and documents on your computer.
Data transfer rate is the rate at which data can be sent or received. This is determined by your motherboard. A drive with a higher transfer rate will only run at the rate of the motherboard's transfer rate.
Cache is a type of working memory that allows the drive to perform faster.
RPM is the rotations per minute of a hard drive which effects the speed of data transfer.
Solid state drives are non-moving memory, so access speed is instant.
I recently purchased 2GB kit (1GBx2) DDR PC2700 Unbuffered NON-ECC 2.5V 128Meg x for an old Gateway E 4100 computer at work. I shut it off, grounded myself and replaced the manufacturer sticks, using the same seats, and couldn't get a video signal when I turned it on. I tried reseating, using the other seats, using just one stick in multiple different seats with each stick and still got nothing. I also tried to use the original memoy that I was replacing and still don't get a video signal. The keyboard powers, the motherboard beeps like it's turning on and I plugged the monitor in to another computer to make sure it wasn't an issue with that. Is there anything I might be able to do to figure out what might be the problem? Thanks!
I installed Crucial memory modules earlier this year while I was running Windows XP. I just reformatted the hard drive and installed the Vista operating system that came with my PC. The add on modules are no longer recognized; only the factory installed memory is visable on a scan. Does this mean that the memory was compatible with XP but not Vista?
I am very sorry for the issues that you have been experiencing with the memory modules that you purchased. I pulled up your system specs and they do appear to be guaranteed to be compatible with your system. If you aren't overclocking them then I would not expect them to "burn" out. The timings for these memory modules should be set to 9-9-9-24 in the BIOS. You may check this setting to make sure it is set correctly. Otherwise, it may just be bad luck with the two memory modules. It's very rare, but may happen. Please contact the vendor you purchased them with or us directly using the information in my link for a warranty replacement. I am sorry for the inconvenience.
Thank you for contacting us today. It does appear that the memory you are looking at matches the specs of the Micron part, but it has not been tested with your system. We can only guarantee these modules to be compatible with your system: http://www.crucial.com/usa/en/compatible-memory-for/ASUS/x99-e-ws
However, if you do purchase that kit with us and it does not work we would be happy to refund it if you return it within a 45 day period. Please let us know if you have any other questions or concerns.
I just found CPU_Z and looked at my memory in one of my old systems.
The system used SDRAM and can accept 66, 100, or 133 Mhz memory
The three chips show up as:
1 100 133
1) Why are multiple speeds shown within the chip?
2) I ASSUME that the chip will run at its highest rated speed?
3) I ASSUME that if the chip is rated higher (142) that it will adjust downward to the re bus speed?
4) My CPU is a 1100 MHz AMD Athlon. The bus runs at 100 Mhz with an 11 Multiplier.
The Front side bus is adjusted automatically (says default is 200) but assue it is also running at 100MHz.
When I set the SDRAM to run at 133 instead of 100, my system becomes unstable.
Why since the SDRAM is rated at 133 MHz?
