Hello, my computer has the following memory KVR1333D3N9 more'm trying to put the other KVR13N9S8
the two are the same Frequency 1333Mhz, are not the same thing then? more when I put the other computer does not liga.agora Intendo that the other does not work, and has the same frequency and both are DDR3.Posso try for the two can occur together or a problem? The problem is it my pc? The board model is the following P5P41C.
Hello,
Yes, both the memory is of the same speed. The difference between them is their sizes and the ranks. KVR1333D3N9/2G is a Dual Rank (2R) 2GB module while KVR13N9S8/4 is a Single Rank (1R) 4GB module.
Try the following -
Make sure you do not have any DDR2 memory installed when you are trying to install DDR3 memory.
Try installing just the 4GB module in one slot and see if it boots. Repeat the same with the 2GB module.
Also make sure if the slots are working
Try Updating your BIOS.
If none of the above works out then I think the issue is the memory rank of the 4GB. Try a Dual RANK 4GB module - Kingston KVR1333D3N9/4G
Or check with Kingston, memorystock.com or crucial.
Good luck!!
Dear sir;
I'm not a computer Guru but a confused and concerned end user about memory compatibility. Hope some computer elites could share some more knowledge.
I'm using EP43T-UD3L mobo (4 slots, supporting up to 16 GB RAM) w/ a KVR1333D3N9/2G stick (almost 5 years-old, some say seemingly quit old for current technology); recently trying to upgrade w/ a KVR13N9S6/2 stick but fail, windows 8.1 detects the new stick as a hardware reserved 2 GB but BIOS cannot detect it at all. I test a KVR13N9S6/2 independently, the system cannot boot w/ this stick. This means the stick is not compatible w/ my mobo as Kingston (KVR1333.......... are all discontinuted) and Gygabyte say so. Now I'm trying to understand the matter by looking into its spec. I find out:
Compatible sticks:
KVR1333D3N9/2G: 2Rx8 = 128MBx16 chips, 8x8bits (Double Rank-using this one now)
KVR1333D3N9/1G: 1Rx8 = 128MBx8 chips, 8x8bits (Single Rank - never try but it's in Gigabyte's RAM compatible list)
KVR1333Ds83N9/2G: 1Rx8 = 256MBx8 chips, 8x8bits (Single Rank - some say it's compatible for its code KVR1333..............)
KVR1333D3N9/4G: 2Rx8 = 256MBx16 chips, 8x8bits (Double Rank - " -------------------------------------------------" )
Non-compatible sticks:
KVR13N9S6/2 (2GB): 1Rx16 = 512MBx4 chips, 4x16bits (Single Rank - try but NOT compatible - look weird for its large the chip size and bandwidth-16bits)
KVR13N9S8/4 (4GB): 1Rx8 = 512MBx8 chips, 8x8bits (Single Rank - some say it's NOT compatible because of its new technology - I don,t know what so new for a RAM or just the bigger size of the chips that matter to my mobo.)
Still wonder:
1. Is KVR13N9S8/4 (4GB) compatible to my mobo for its bandwidth-8bits but no matter for the chip size-512MB and RANK?
2. What are truely made RAM non-compatibility - rank, chip size, bandwidth or some other hidden tiny things inside the chip? How could I know which other brand RAM would be compatible to my old-tech mobo? or I've to buy them all just to test and trow money down the drain!
3. From an end user and a consumer points:
Is it too difficult to manufacture a new technology (say just a RAM stick) to be compatible w/ the old one (let's say my old-tech mobo)?
Or it's just the marketing gimmick to have people trow the old tech away completely (mobo, CPU - for the sake of RAM compatiblity. Is this seemed a little too much to take advantage from all consumers? Why don't they let the consumers themselves decide when and how to turn to the new tech?
Is there anything concerning Life Time Warranty of the RAM for its discontinuing would void such Warranty automatically? But when the Warranty stands; the replacement would be a new non-compatible tech, therefore we have trow the old tech (mobo, CPU) away anyway!!!
Wanna test a KVR13N9S8/4 (4GB) stick w/ my mobo too. But a second thought tells me that "why wasting time and money", give up and just turn to a new tech system, better!!!
