Ram wont work with computer

My motherboard has Two DDR2 DIMM slots, Accepts DDR2 533/667 MHz single channel modules, and is Expandable up to 2 GB. Now I bought the CORSAIR Value Select 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 533 (PC2 4200) Dual Channel Kit Desktop Memory and when I put both piece of ram in it doesn't work for some reason. But only when I put 2 in, when I put 1 in it works and i dont know why. So is it because my motherboard is single channel modules when the ram is duel channel kit?

    did u try both dimms individually, that is one at a time? in the same memory bank? (lets say dimm1) and both individually worked OK, but when used simultáneously don´t work? does your motherboard support dual channel memory? and what frequency is the front side bus of your microprocessor? Is it all balanced?

Dear user in my observation this is sauses due to two different bus speeds. i mean both RAMs dont have the same bus speed. thats why both RAMs dos'nt work at the same time. hopfully u will understand it

I have intel dg41rq motherboard with 2 gb kingston 667 mhz in one slot. can i put another 2 gb ram in other slot. if yes then should it have the same specification?


Intel DG41RQ Motherboard has two DDR2 (DIMM) sockets.
It Support DDR2 800 or DDR2 667 MHz DIMMs. Since you already have a 667 MHz RAM, it is recommended that you add another RAM of the same specification (DIMM DDR2 667 MHz)
However, if you add 800 MHz DIMM with 667 MHz, both would perform at 667 MHz. RAMs of different bus speed and latency usually work together but the performance is compromised.
It is always better to have RAM in pairs of same specification.

Hope it helps! Good Luck! Thanks for using Fixya!

Please tell me which type of support for D102GGC2 for 2gb ram i want extension ?


Your motherboard have the following specifications:
Two 240-pin DDR2 SDRAM Dual Inline Memory Module (DIMM) sockets
• Support for DDR2 533 MHz and DDR2 400 MHz DIMMs
• Support for up to 2 GB of system memory

So either get 1 2GB RAM DDR2 with 533 or 400 MHz. It is maximum for your motherboard or have 2 1 GB accordingly.

Just bought 2 1GB PNY dual Chanel memory modules for my Computer Make: HP Pavilion 061 Computer Model: RJ181AA-ABA a1600n Currently has Memory: 4 slots: 512 MB, 512 MB, empty, empty QUESTION: which slots...


Hi,

Start off by putting the first memory module in DIMM slot 0 this is the slot nearest the processor. DIMM slot 1 is the slost after DIMM 0.

I am using this ASUS (asus M2N-MX nvidia mcp61p chipset


According to the manufacturer's web-site:

http://usa.asus.com/product.aspx?P_ID=0pKBwEIE8tqMT4j7


this motherboard has 4 x DIMM sockets,
supporting a maximum of 4 GB
of DDR2 800/667/533/ Non-ECC, Un-buffered Memory

and supports Dual Channel memory architecture.

So, add one 512MB DDR2 533 Mhz RAM into one of the slots,
being sure to leave *ONE* *EMPTY* slot between the two sticks,
in order to enable the high-performance "dual-channel" option.

Try your computer -- it should feel faster.

If you still think that need more RAM, buy two 512MB (or two 1024MB) DDR2 533 Mhz RAM, putting the 2 sticks into the two empty slots.

Intel 102 motherboard


If your Intel motherboards model number is D102GGC2 you can run up to 2GB of memory. Two 240-pin SDRAM Dual Inline Memory Module (DIMM) sockets, 533/400 MHz single channel DDR2 SDRAM interface Designed to support up to 2 GB of system memory Use one GB in each DIMM slot for the total of 1GB.

Ram issue with compaq presario 5000 G1 Series


as you can see from the information below there are different requirements for RAM to work stable in your system . Most importand are the RAM VOLTAGE , SPEED , and Configuration of chips. you will need to consult the manual for qualified RAM requirements. Some RAM will work but not very stable. make sure the voltage supplied by your system is enough for the RAM. If you are running DDR RAM in dual channel mode, the ram needs to be the same size also. DIMM modules for the HP computer must meet the following requirements
  • The number of pins on the DIMM must match the socket type.
  • DDR memory requires a 184-pin slot and 1.8 operating voltage.
  • DDR2 memory is not compatible with DDR1 memory and requires a 240-pin slot and 2.5 operating voltage.
  • Synchronous dynamic random access memory (SDRAM): Only use DDR type SDRAM memory if the computer came with DDR-SDRAM.
  • SO-DIMM modules for the HP computer must meet the following requirements
    • The number of pins on the DIMM must match the socket type.
    • SO-DIMM memory requires a 200-pin slot.
    • DDR2 SO-DIMMs are not compatible with DDR1 DIMM and DDR2 DIMM memory modules.
    • With a computer running at a system bus of 533 MHz or 667 MHz, use a PC2-4200 (DDR2 DIMM 533) type.
    • The following requirements must be met for the DDR memory to function in dual channel mode:
      • Same density (256MB, 512MB, etc.)
      • Same DRAM chip technology (x8 or x16)
      • All either single-sided or dual-sided
      • Matched in both Channel A and Channel B memory channels

RAM NOT DETECTING


I had the same issue on this board where it came with a Samsung 512 MB 533 MHz PC2-4200 DDR2 DIMM. I put in a 1 GB Kingston with the same specs (533 MHz PC2-4200 DDR2) and it would not recongize the Samsung anymore with the system reading as 1 GB of RAM instead of 1.5 GB. Tried every configuration and would only see the Kingston. It would only see the Samsung if I pulled out the Kingston regarless of the slots I use. So, I just bought the exact same make/model of Kingston and it recognized that fine and the system now has 2 GB of memory (max this board allows). And, I had already installed the latest BIOS for this board from Intel before doing all this so wasn't an old BIOS. I'm figuring the board didn't like something about the Samsung memory (speed, module configuration, etc.) that made it not play nice with the Kingston. If interested I bought the DM8400A/1G Kingston modules. And, this board appears not to support dual channel memory. Only has channel A, slots 0 and 1, and I read need two channels to support dual channel (seems obvious). Boards that supports dual channel memory normally have 4 memory slots, two for channel A and two for channel B, then put in matching modules in slot 0 for channel A and B and have dual channel memory access. And if want more ram, then matching modules in slot 1 for channel A and B.

Ram upgrade


In order to see how many MHz is your desktop, please right click on your "My computer" icon and select "Properties" from the menu.
It will open the system properties window. select the tab "general" and you will see how many MHz is your desktop.
