I have a RAM disk (Romex) that is reported to the system as a SCSI fixed disk. I want to use it for ReadyBoost. I am pretty sure it is fast enough for ReadyBoost. However, ReadyBoost tab does not appear in the properties of this disk. How can I force the system to use it for ReadyBoost?
Reason: I use Windows 32 version, which cannot access memory over the 3 GB threshold. However, this RAM disk is installed in the OS-invisible memory, which I want to use as disk cache via ReadyBoost.
Alternatives I tried:
Direct-IO Romex RAM disk. ReadyBoost option is available, but when I try to use it, the error message says something like "Cannot create cache memory. Request not compatible." (my translation). I successfully use it for paging file.
Romex PrimoCache. It seems it causes system instability (maybe incompatible with CrashPlan), so I disabled it. Note that the cache should be located in the OS-invisible memory. Anyway I would not like to mess with caching other than ReadyBoost, because I am not sure how it would be compatible with CrashPlan.
