    S3 Sleep ONly Works w/2GB DDR2


    Older Shuttle SG33G5 with Core 2 Duo E8400 running Windows 10 Professional. System works great except for one thing - it won't come out of S3 sleep if I use 4 GB of DDR2. This is a two-slot dual channel motherboard. I have quite a bit of spare DDR2 and I've tried them all, the behavior is the same. If I install two 1 GB sticks, S3 sleep works perfectly, clicking the mouse or tapping a key brings the system out of S3 quickly. When I install two 2 GB sticks, when I click the mouse or tap a key the power light goes on, the fans spin, and I get a blip of activity from the HD - then, nothing. Screen remains blank, no further activity, fans continue to spin and power light remains on. Nothing I've tried on the keyboard brings the system back up or shuts it down.

    If I hold the power button until it shuts, off, then turn it back on, it boots normally, except - it bypasses the logon screen, just as I have it set to do when waking from S3.

    I've tried every combination of BIOS settings I can think of, S1 instead of S3. tried various DDR2 speeds, looked at all the HD settings, etc., to no avail. Currently, I'm just using hibernation instead of suspend, a little slower, but it works.

    Why would the amount if DDR2 memory affect waking up from S3? The system has a brand-new 350W power supply and I looked at all the voltage outputs on an oscilloscope, they're perfect (no ripple or noise) and the voltages are spot on. Any ideas would be appreciated, thanks.

    Having issues with computer going into "sleep mode" after 2-3 minutes even though the settings are set to "never"

    Here is the output: (should I expect something different?)

    Platform Power Management Capabilities:Supported Sleep States

    Sleep states allow the computer to enter low-power modes after a period of inactivity. The S3 sleep state is the default sleep state for Windows platforms. The S3 sleep state consumes only enough power to preserve memory contents and allow the computer
    to resume working quickly. Very few platforms support the S1 or S2 Sleep states.

    S1 Sleep Supported
    false

    S2 Sleep Supported
    false

    S3 Sleep Supported
    true

    S4 Sleep Supported
    true

    Platform Power Management Capabilities:Connected Standby Support

    Connected standby allows the computer to enter a low-power mode in which it is always on and connected. If supported, connected standby is used instead of system sleep states.

    Connected Standby Supported
    false

    I am grateful for your help. The only thing that solved the problem was changing memory modules with new ones with same fsb ddr2 2gb 800 mhz. Probably the old ones were ddr2 2 gb but 800mhz and 400mhz. Thank you very much for your help. And I would like
    to mention also that now I have memory modules of 8gb total and my motherboard seems to support them. Every thing seems to be going quicker now.

    S3 Sleep ONly Works w/2GB DDR2

    Same issue with 8GB RAM (4 sticks DDR2 800 Kingston) / Windows 10 PRO.
    When RAM is GANGED MODE (dual channel), my PC won't wake from S3 (PC on and Screen off). In UNGANGED MODE, my pc wake from S3, but rarely not fast (about 2 mins) or not wake. I've not tested RAM, but in normal use, i not ever had BSOD. Try to disable ganged with 4 GB installed.

    -- UPDATED --
    Bios reset disabled wake from usb mouse and keyboard (my keyb is PS/2) and now wake from s3 seems to work.
