Can i use DDR2 AND DDR400 at the same time?

Hello,

I have a PC Chips P23G V3 motherboard which has 2 x DDR2 533 slots AND 2 x DDR400 slots.

Ive got 2 x 1GB sticks of DDR2 installed and would like to increase my memory to 4GB (running Vista Home Prem 32-bit).

I'm not sure if my motherboard would support an increase to 2 x 2GB of DDR2 or if I am able to add any DDR400 as well, so before making a purchase I'd like to find out what you would recommend?

Many thanks,
Paul.

  1. According to my knowledge, I dont think you'll be able to use both of them simultaneously.
    My suggestion is, if your motherboard really supports DDR2 memory, then sell your ddr memory, and get 1 ddr2 memory of 4GB.
  2. no you cant use both at the same time.
  3. impossible to do that.
  4. Many thanks for such quick responses.

    Sticking with the DDR2 memory - do you think that my motherboard would support an increase to 4GB, and if so, would I be better buying a pair of 2GB or just 1 stick of 4GB? (I thought I had to buy pairs having 2 slots?).

    Is DDR2 better for me than DDR400?

    Thanks again.

  6. Is this what your motherboard looks like?

  7. If yes, then first thing, you cant go beyond DDR2 533.
    And the second thing, your motherboard supports maximum 2GB RAM.
    It wont support 4GB.
    Either change your motherboard, which leads you to change the processor too.
    Or stick to 2GB of RAM.
    Choice is yours..!!

    Yes, thats exactly my motherboard - thanks for your confirmation, what a pain! Guess I'll have to stick with what I've got for now, I'll probably just get a new desktop when this dies rather than try and get a new motherboard and CPU as I'm not that technical etc.

    Thanks again for your help, really appreciated,

    Paul.
  9. Getting a new desktop when this one dies, it points towards 'Never'.
    Try one thing, sell this CPU of yours, I mean case, motherboard, ram, processor, graphx card, dvd/cd drive, keep your HDD. Sell everything except your HDD, keyboard mouse, display, speakers in a possible good price.
    And get a new one immediately.
