    RAM Upgrade question

    Locked

    by jimdana1942 ·

    For further clarification, I am adding a 64Meg ram module to my existing 64Meg; the new one is a 133 mhz SDRAM DIMM 168 pin; my existing one is a 100Mhz SDRAM DIMM 168 pin..does the 133 have to go into the FIRST RAM slot or can it go into the currently empty 2nd slot…will the BIOS detect it in the 2nd slot?

      It shouldn’t matter which slot it is in. The BIOS will detect it BUT it will only run at 100Mhz, the same as your existing RAM.

      Since both DIMMS are the same size, which DIMM goes into which slot depends on whether you are after speed or stability.

      For system stability, you need to check what the Cass Latency is for both DIMMs before you decide which DIMM goes into whichslot.
      This is usually on the label on the DIMM and is often abbreviated as CL.

      Place the DIMM with the largest CL number in slot 1. This way the BIOS will set the default timings for the longest latency memory thus maintaning system stability.
      Or, you can always set the refresh rate and CL manually in the BIOS. Just be sure to set them for the worst case if system stability is your goal.

      Also, it would be a good idea to blow out the open slot with canned air prior to inserting the DIMM.

      Many mother boards do require that the largest DIMM be in the first slot. But, this doesn’t apply here since both DIMMS are the same capacity.

      Answer number 1 is correct accept using one slot or another depends on your motherboard and bios. If this is a newer computer it will probably not matter as most later PC’s will aut-configure memory position. Older PC’s may require a specific sequence. Try one way then the other if first way causes problems, thats all.
