View Thread: 4 gigs of ram slower than 2 gigs of ram??
  • User profile image

    Hi im not sure if this is the right place to post this but im having a problem. I just bought another 2 gigs of ram so i have a total of 4x1 gigs of ddr2 pc8500 ram. Problem is when i use memtest86 v3.4a i see my bandwidth is 3200mb/s with 4 gigs. It used to be 5000mb/s with 2 gigs. I use other tools to benchmark as well such as SiSoft Sandra. I run the memory bandwidth test and it told me i had around 7500-8800mb/s with 2 gigs. With 4 gigs i Sandra now tells me i have 6200mb/s. I have not changed the bios since. My system is as such

    Vista Ultimate 32bit
    Q6600 @ 3.2 ghz
    GA P35 DS3R rev 2.0 bios f6
    4x1 gigs Crucial Ballistix ddr2 pc 8500 @ 1068mhz 5-5-5-15 2.2v

    There are no errors in memtest but it takes triple as long to complete the pass. I am also aware of the 4 gig problem with 32 bit. My OS recognizes 3.5 gigs. Any help would be appreciated
