Please, someone give me a fix.
amatotg Something to be aware of here is that resume from sleep issues can be caused by Windows and/or hardware. This isn't just a single issue attributed to Windows 7 SP1 updating in ALL cased. I own the X58 760 Classified and been having issues with resume from sleep since the BIOS versions started to hit the versions enumerated in the 70's. Interestingly enough, 77 was kosher, even with SP1. I just upgraded to 78 last night and now the problem isn't just intermittent like I had experienced back at BIOS 74 (if I remember the version correctly) but it's hard and fast now each and every time. When the mobo goes through initial POST routines and your Power LED mysteriously comes on and then goes off just seconds after hitting the mouse, keyboard or power button - that's indicative of a BIOS/mobo POST initialization problem and has nothing to do with Windows - be it the base kernel or a SP. eVGA needs to get this sorted because BIOS 78 with the Intel Rapid Storage firmware update has the problem in it - and like I said - it's hard & fast repeatable.
dilburt This is a problem with all X58 boards. There are lots of posts about it on every motherboard site. The root cause is that the DDR voltage is set to default during S3 sleep mode. This is why many support people don't find this problem because it won't affect the system unless the RAM is overclocked to some combination of settings that require more than the default voltage and support people use stock settings. For example, my Corsair XMS1600C7 RAM runs at 1.5v for the stock SPD table frequencies and S3 sleep will work with these settings. As soon as the RAM is set to 1.65v for the XMP timings or above the S3 sleep fails. You can easily prove this to yourself. Hang a volt meter on the DDR test point and start your system with a configuration that requires a DDR voltage over 1.5 volts. Enter S3 sleep and watch your volt meter drop from 1.65v (or whatever) to 1.5v during S3 sleep then move back to 1.65v when you resume. This lack of voltage causes RAM corruption which is the true root cause of this problem (S3 is also call "suspend to RAM"). Most people report their CAS timing has changed after running this test. Unfortunately, there is no work-around although some people say that some manufacturers have figured out how to fix it in BIOS for some boards. I cannot verify this. - D
