EP45-UD3P Q6600@3.2 S3 mode reboot loops

[Gixxer1kr]

Can someone please help me set this up correctly? I have a stable system running at 3.2Ghz passed mem test and prime and been using this for 9 months without any problems. I am trying to get S3 mode working but am only successful with stock speeds.I know that I have to change my auto settings but don't know the correct values.PC goes to sleep but won't wake.

I had the same problem when I updated my bios from f7 to f10e with my e6750.

suprisingly, it resolved when I switched to a q9550.

I think the difference is that I used a higher MCH voltage on the q9550.

The other thing I would recommend is taking your voltages off auto.

Many settings left on auto, see this post for what should and what should not be left on auto.
Please fill your signature with you system spec, including a link to ram specs (manufacturer site prefered).
Also Post a screen capture of EasyTune advanced voltage tab, and MemSet main and spd(click spd) windows.
MemSet can be found in Latest Overclocking Programs, System Info, Benchmarking, & Stability Tools

I have the exact same issue with S3, and don't have any voltages on auto. No amount of tweaking has solved the problem for me. You may find that you can never get S3 working.

I bet you wouldn't have any problem at 3.2GHz. I managed to fix my S3 problem up to 3.5GHz.

[Psycho101]

I may or may not have the problem at 3.2GHz, I'm not sure. However that's pretty irrelevant, as I'm not going to be running my PC at 3.2GHz.

3.4GHz, 3.8Ghz and 3.9GHz all fail to resume from S3 for me. Haven't tested 3.2GHz and don't intend to. Even if 3.2GHz does work for me, it still may not for someone running a Q6600. Time will tell.If the OP takes all settings possible off auto and adjusts what he can, and it still fails, I'd personally chalk it up to another casualty of the Gigabyte S3 mystery.

[Chike]

All it took for me to fix it at 3.4GHz was to adjust CPU Ref one notch down, from auto (0.805) to 0.785.
Regardless if the S3 problem will be solved, I am sure the auto settings set unnesessary high voltages and will do no harm to set them to more sane values.

Ok, I went and redid my settings starting off by Loading Optimize Defaults and rebooting. I then changed all my "Auto" to what I think they should be after reading that post you directed me to. I edited my first post to reflect my current settings. Here are the screen shots you requested. I also updated my sig.

Thanks,

I see you are using 2 different 4GB kits, can you post screen capture of MemSet spd window for slot#2 (the other pair)? Alt+PrinScreen will capture the front window only.
Of course you will need to run stability/stress tests to verify the new settings are OK.
Have you ran any before? What are load temperatures and what king of CPU coller you have?
The references voltages are safe being left on auto unless you have make/made changes to them.

My cooler is XIGMATEK HDT-S1283 120mm Rifle CPU Cooler

I ran test when I first built it and load temps were around 55-57
