FSB 800/533 MHZ

System HP Pavilion a1324n asteropeA-GL8E ,motherboard ECS RC410-m, socket 775,PC2 4200 SDRAM 240 pin, 2GB max HP approved,northbridge chipset. How do I change FSB to 800 MHZ if possible and can I get away with boosting my
mem to 4 GB? My system is off the shelf and is running at 52 C. Would these changes if possible make it run alot hotter?

  1. That board is not able to handle more than 2 GB total memory:

    Single-channel memory architecture
    2 x 240-pin DIMM sockets support unbuffered non-ECC 400/533 MHZ DDR2 memory modules
    Maximum HP/Compaq approved memory is 2 GB

    If you want to utilize the 800 MHz FSB..you will need to upgrade the memory to DDR2 PC2 6400 i.e. DDR2 800..
  2. Replaced the mem with 6400 800MHZ ,no change in speed and bios still says 533 FSB. Do I have to do any other changes to get the ram to run at 800 MHZ? thankyou.
  3. That boards chipset will only allow the RAM to run a maximum of 533 MHz...Your MOBO automatically underclocks your 800 MHz mem sticks to 533 MHz....You will have to change your motherboard if you want to run faster mem. modules.
  4. Would have been nice if you told me about the motherboard when telling me to boost my mem to 800.
  5. Sorry, if I got ahead of myself.... yet I did state the boards specs. were maximum of 2GB @ 533 MHz.
