Hello,

Ive read a bunch of posts but it sems like i have a unique problem with the "hardware reserved memory problem..now bare with me because i dont know a lot of the technical stuff but...i have a toshiba l655d s5050 laptop with AMD athlon II. It has wondows 7 64 bit..it originally came with 3gb of ram and when i would check the ram usage in resource monitor it would show only 961mb of usable memory..the rest was hardware reserved. so them i decided to buy more of the same ram which is DDR3 so-dimm 204 pin 1066mhz pc3 8500 ram..i ended uo buying a g. skill 4gb mem stick..i put it into the slow where the 2gb stick was and moved to the 2gb stick to where the one GB stick was and then i have 4GB hardware reserved...after playing around with the memory sticks for a couple minutes..turning the computer on and off i realuized that whichever stick was in the second slot was hardware reserved...the computer is working fine now because i have the 4gb in the "good slot" and i have the 1gb stick in the "hardware reserved slot" and the 2gb stick is just sitting on my desk because i find it pointless to have it in the computer if

  1. Send us a Screenshot of your setting in CPUZ if you don't have it download it from here.... http://www.cpuid.com/softwares/cpu-z.html
    Give us the screens of Memory & SPD.
    Try to take both screenshots for SPD of all the slots.....
    I have a feeling it's got something to do with Dual Channel and Single Channel...
  2. I really appreciate your time in helping me with this!!!!!! I was worried noone was going to help! Now bear with me because i am not extremely good with computers so what is SPD?
  3. ok I am having trouble getting a screen shot..i tried the F7 key but i didnt do anything but i was able to upload the informatio to the cpuid website but i can go through the tabs but i was able to copy some of the information right from the page it loaded to on the website

    here it is:


    AMD K10
    Windows 7 Home Premium Edition (Build 7600)

    Slot 1 Manufacturer : Samsung
    Slot 2 : 4096MB (8500)
    Slot 2 Manufacturer : G.Skill
  4. it does say i am in dual channel on the memory page..i know dual channel is better for speed and bandwidth but could that be the reason I am unable to use whatever is in the one slot?

    both ram modules are running at the same speed -533mhz
    both have the same timing and seem to be the same in every area when i look under memory.

    I am so grateful to have someone helping me with this!! I have read and read and read online and i cant seem to find a fix for this....
  5. That's a Tab on the CPUz window, it's basically serial presence detect and is used to detect the setting of RAM timings and voltages on the Mobo....
  6. heres some more info:

    Memory page:

    Channels #- Dual
    DC Mode- Unganged
    NB Frequency- 1595-1600MHz
    DRAM frequency- 532mhz
    FSB:DRAM- 3:8
    CAS#Latency(CL)- 7.0 clocks
    RAS# to CAS# delay- 7 clocks
    RAS# precharge- 7 clocks
    cycle time- 20 clocks
    bank cycle time- 27clocks
    command rate- 1T

    ok i figured it out...i wasnt sure until i downloaded the program and then saw the tab..That is a really nice little program to have to give some good information about the system!

    have you found anything wrong with the data yet? Should it be in dual channel?
  8. Yes it's dual channel so it should show both as dual channel.....
    Unless one of the mem specs is different.
    I'd really appreciate a screenshot.... and I don't think it's F7 but the shift PrintScreen is good.......

    i have the screen shot but i cant figure out how to get it posted to a reply on this site (tomshardware)
  10. Upload it to any of the free pic sites and post the image code or link here.....

  12. here ya go! Let me know if you need any other pics! I didnt know about the snipping tool before so I was quite confused on how to get a screen shot...My last laptop had XP and i dont think it had that option..I also have speccy if you want any screen shots of that
