Q:I have a Dell Dimension 8400. I want to take out the memory and add 3GB of higher speed memory. These Crucial 1GB modules seem to have the same specs as memory which Dell says is compatible with my 8400. Yet Crucial's Memory Advisor says this module is not compatible. Is this correct?
A:Only PC2-5300 modules will work in this system:
Q:What does the 6400 stand for
A:PC2-4200 (DDR2-533), PC2-5300 (DDR2-667), PC2-6400 (DDR2-800), and PC2-8500 (DDR2-1066) memory are all types of Double Data Rate, second-generation SDRAM, usually referred to as DDR2. The varying numbers refer to the different speeds of memory your computer was designed for. PC2-6400 (DDR2-800), which has a bandwidth of 6.4GB/sec and is designed for use in systems and motherboards that require a 400MHz front-side bus, with an effective front-side bus speed of 800MHz.
A:Its referring to the speed of the ram itself in technical terms mostly labeled on the packaging of the item. A dimm module for example a 2gb 800mhz 240 pin PC2-6400 is clocked at 800mhz so the 800mhz is multiplied by 8 bit (smallest digital character) which equals 6400(800x8=6400), same thing goes for a dimm(ram) which is clocked at 667mhz then this would be 667x8=5336 but on the box of the ram you'll see PC2-5300.
A:The 6400 is basically the speed that the RAM runs at. Not sure what the speed is measured by (GHz or MB ect) but naturally the higher the better, however, if you are installing more RAM into a computer then the RAM will only go as fast as the slowest RAM already installed.
Thanks for your message.
I have had a look in to this and unfortunately I have been unable to find an installation guide for this specific model. I would recommend contacting Acer directly who will be able to provide and installation guide for you.
I checked with the Acer website for an instruction manual but they don't have any listed. I am sure if you contact them directly they would be able to help.
Please let me know how it goes and if there is anything else we can help with.
I just got a new Crucial ct102464ba160b http://www.crucial.com/usa/en/ct102464ba160b
based on the suggestion here http://n40l.wikia.com/wiki/Memory that it is compatible with
HP Microserver N54L
My system runs fine the the original 2GB HP memory but when I put the Crucial stick in
it doesn't POST (can't see anything on the screen at all).
How do I check whether the RAM is not compatible or it's simply a DOA?
I ran the scan, it takes me to this page,
CT3694396 - 8GB DDR3 PC3-12800 Unbuffered NON-ECC 1.5V 1024Meg x 64
I have 2x Crucial DDR4's CT8G4DFD8213 in an Asus X99 Deluxe mother board with a Intel 5820K. System boots fine but only shows 8gb of memory in the POST and in BIOS only shows 8gb in DIMM_D1
I have the other 8gb in DIMM_B1 which is the reconmmend configuration for two DIMM's.
I have tried each DIMM in DIMM_D1 to confirm the memory is OK, which it is.
I also updated the BIOS reversion after my troubles to the latest version 904 though I didn't think it would really do anything as the change logs for the BIOS update seem to address other issues and not memory issues.
So I think this memory is maybe not compatible with the new Asus X99 Deluxe mother boards.
I am sorry for the issues that you are experiencing with your memory modules. I pulled up your system and it appears that these memory modules are compatible with your system. At this point I would test each stick individually to see if it just one defective stick. You may even try running each stick individually in the system to see if the error occurs. Please contact us directly, using the information in my signature, if you are still experiencing issues.
