He had a failed memory module, but probably good for reference
I got home after a three hours in class. I started back the test once I got home with 3 sticks. Two in the blue and one in the black (The three I know are clean). So far, MemTest is picking up 24543M of Ram half way done with test 5. No errors so far.
So its a possibility the RAM stick you don't have inserted is the bad one. If you were to remove the 2 in the blue and insert the other one in the blue or the black, there should be memory errors all over the place.
Bad memory will cause a wake during sleep as the data stored in RAM would be damaged, and that would cause wake issues.
Yup. Because in sleep mode, Windows saves its Data to RAM so when you wake it, everything will be the way it was when it entered sleep.
If you have a bad memory module, you will have 2 issues. The computer will either wake without warning, and your memory usage will be much lower as the memory stored in RAM was damaged, which could cause programs to fail, or even cause a bsod.
Another thing g that would happen is your PC may shut off without warning, like its going into a hibernate state. But when you restart the computer, it will either begin automatic repair and say that Windows didn't start successfully, or it will start up normally like a cold boot. It's rare, but it happens. I had an old lga775 board with Windows 7 and had issues like crazy with sleep. It wouldn't stay asleep for more than an hour, but had figured out the board had a bad memory bank
But I had the board 3 years before that started happening. I forgot all about that board. It was a PCChips P17G/1333 board.
Hmm that is odd. I guess some machines just want to be goofy sometimes.
Oh, and not sure if I asked, since I see you've had this board a while. Did you update the UEFI to the latest 2501 BIOS? That is the best BIOS right now.
Also, hoping you got the bad stick out finally.
Since you have gotten 3 sticks with no errors, also put one of those sticks in the other black slot to just make sure its working. Also then boot to Windows and test your sleep issues and see if they reoccur.
