Occasional stop 0x0000077 BSOD

[gigel2007]

I'm using host os invisible memory (~764 mb) for a ntfs ramdisk and I've put the pagefile on it.
I sometimes get bsod like this

ms kb 315266 says the second parameter indicates the cause of being impossible to read from the ramdisk, but they do not have 0xc0000011 in the list

I've let the system perform a full nights' memtest86+ and found no errors.
Other than sending you the memory.dmp's is there any other thing that I can do to help determine the cause of this? A debug build if vsuite maybe?

Did your computer enter hibernation state?

PS. VSuite Ramdisk is replaced by Primo Ramdisk. You may try Primo Ramdisk for better performance and features.
Thanks.

No, the computer it's always on.
For the moment vsuite covers my needs (bonus it's free)
