Hi All,
Just a little tale about hibernation and memory for your amusement.
My trusty "workhorse" is an AMD Athlon 64 2.4 GHz in a Biostar Group N68PA-M2T 5.0 motherboard. I am running XP Pro with SP3 and all hotfixes installed. I am not overclocked at all. This is a basic self built system that I put together in 2008. It originally had only 1 Gig of generic DDR2-667 RAM, but it ran without lockups, blue screens, etc. I would shut down using Hibernate and all was good; about every 2 weeks or so I would shutdown just to get a clean reboot.
Shortly after I added another 1 Gig of generic RAM, and immediately when trying to hibernate the PC would lock up. I would have to power down and power up to reboot. So I gained 1 Gig of RAM to 2 Gig, but I lost the ability to hibernate.
My system stayed this way until just recently when I bought 4 sticks of Kingston DDR2 memory. I tried to add just 2 sticks of Kingston to bring my PC up to it's max of 4 Gig, but the PC would not even boot; it was spitting out BIOS beep codes. I tried reseating to no avail. I finally thought " The hell with this bs! " So I pulled the 2 generic sticks out and added the other 2 sticks of Kingston, bringing me up to 4 Gig of Kingston in my PC.
Like magic, not only do I have 4 Gig of DDR2 in my PC, but it now hibernates again.
So much for memory compatibility, eh?
Regards,
Mike

Not all RAM is the same, and sometimes they are even mislabelled. Plus one of those two could have been bad, did you run Memtest on them?

Hi Tripredacus,
Yes I ran memtest86, I think it was. Once I determined that I had questionable RAM, I just bought 4 sticks of the good stuff. It is just funny that the system ran with the 2 good sticks but wouldn't hibernate with them.
