H55N-USB3 won't come out of sleep reliably

[mhamilton69]

H55N--USB3, i3-530 Sandybridge  processor,  Corsair CMX4GX3M2A1600C9  2G x2.
Lite-on SATA DVD , Samsung SATA 500GB SATA HDD
Window 7 Pro 64-bit

When coming out of sleep (s3) (from Window Media Player trigger to record TV show) the system lights up for about 3 seconds, power supply spins up, and then shuts down. Repeats infinitely until I unplug the system.

I've updated to the latest the BIOS.
No overclocking.
Hybrid sleep is turned off in W7.
The memory recommends 1.65 V so I set the BIOS to 1.66V.  (not using enhanced profile)
Tried 2 different power supplies. (220W)

System runs fine when doing a full boot.

What do you think about the following possibilities
1) Power supply or on-board converters are not good and causing memory fault
2) Memory settings need to be tweaked
3) voltage settings need to be tweaked  (for CPU? )
4) Mother board is faulty
5) Memory is bad match for the board (although it is approved by Corsair)
6) CPU is faulty

I've seen postings of similar problems for various Ggiabyte boards, but I don't find a common solution.
If anyone has this board running reliably  as HTPC with frequency Sleep-Wake cycles, what memory are you using?
Did you find any special BIOS or W7 settings?

Hi mhamilton69,

What is your version of Bios?

EDIT: I view you have F5 Version.

What is your model of PSU?

Have you read this Topic :

I tried two power supplies, the generic 220W supply that came with the Chassis and also I tried a 160W PicoPSU.  I have read threads where people are having similar problems with much larger PSU, so I am thinking this is not the problem.

I did read both of the threads you showed.   Since my unit is trying to come out of sleep, but fails, I don't think the first thread is relevant.
The second thread which is suggesting changing RAM may be relevant. I sent PM to that user to find out which RAM is working for him.

I am using Corsair RAM which should be reliable according to most users.

Hi mhamilton69,

it would be you can try a higher power 600W if possible.

Can be a friend, neighbor or try it in a store.

If you have a second pico PSU. Try one for cpu and second for other hardware.

The PicoPSU  has 1.5 Amps (2A peak)  on the VSB (V stand-by).
The chassis PS (Inwin,  TFX form factor, 200W)  has 2A VSB (2.5 A peak)

Hi,

You have the ability to use both the pico and the normal PSU, chassis PS?

Just try it, if the PicoPSU has not enough juice, it will either not boot at all or crash/reboot when it tries to load Windows. (these are the typical scenarios.)

EDIT:
Green & Black , if I am right on ATX power supply. you place a paperclip into connector.

Check this shema:

SFX Power Supply connector pinout

As in the test power supply, you can attach a link between green and black connectors on ATX PSU.

OK I can try , but remember, the system is in sleep mode, it is not a cold boot.  It is not re-loading windows.
The pico works great every time when doing a cold boot. It is only waking from sleep that is the problem.

When using the PICO, the 12V power for the CPU (4 pin connector) is coming directly from the main DC-DC supply which is Dell Optiplex DA-2 (220W).

Hi and welcome.

The figures all may add up and make sense when you calulate them but the PSU is far too small and I wouldn't use any PSU that came supplied with a chassis. It is bound to be crap. Don't try and cut corners espcecially when it comes to your power supply. Even if you are adamant and don't want to fit a decent sized PSU I would strongly advise you to buy a good make (Seasonic, Corsair, Thermaltake, Enermax, Gigabyte, etc) and model of something upwards of 400w. The manufacturer recommends 500W minimum.

The other problem with resuming from sleeep is that the system must be 100% stable for it to work properly so the chances  are that something is not working as well as it could be.

Your memory should be fine with that board. However that is not to say that it's not faulty. You could try running Memtest on it to make sure. If you want to follow these instructions:

Please follow these instructions exactly.

I would suggest that you download and run the latest version of  Memtest86+ to check your RAM first.

Memtest86+        http://www.memtest.org/

Insert one stick of memory in slot 1 and run Memtest on it for at least 10 complete loops/cycles and if there are no errors then swap it over with the next one and continue untill you have checked all  modules.
 
If you have any errors the module is faulty.

If you have any faulty modules you will have to return the whole kit as they are matched.

Post back when you have done that with the results.
