Memtest86+ with 4 gigs

  1. Hi,

    I'm trying to run memtest86+ with four gigs of ram, but it is only testing three of the four. How can I get it to test all four?

    I will guess you have Windows XP 32bit OS Version, that only recognises 3Gb roughly but that isn't the cause Memtest86 should still detect it. If you haven't already check that the RAM cards are properly seated and then try running Memtest again.

    It recognizes all 4096, but the current test only goes up to like 3048.

    Windows issue with either the Windows install, or the motherboard. Move the modules around to test the one that it is missing.
    MemTest will test all that are detected by the motherboard AND Windows. What does your BIOS report as installed.

    Are you booting from a memtest86+ ISO?

    If not, you should be - download the ISO, burn it to a disc, then boot your system from that.

    If you are, tell me.

    Wow... it is pretty old. I don't know why Ubuntu doesn't update it. Oh well. I ran the new one and it found no errors too.

    On a side not, I made an interesting observation. I've been downloading the Warhammer Online Beta client (get ready for WAAAGGHHH Sept. 18), and I've had uTorrent running pretty much 24/7. So, I tried closing uTorrent, and I didn't have a crash, and I waited 3 hours (It normally crashes between 30 minutes and 1 hour). So, I tried running Azureus, crashed. So I'm not sure why running torrents makes it crash.
