Enabling 'Read Caching' with nVidia 5.10 platform drivers

[ecskier]

Don't know if anybody has posted this yet, but I was able to use regmon to find the registry keys that enable the greyed check box for 'Enable Read Caching' with the nVidia 32bit platform drivers.

I can't give you specific keys that you need to change because it will be different for everybody, but search the registry for a DWORD value named 'ReadAheadEnabled' (I'm pretty sure there are two per hard drive on your system). Change the value from 0 to 1 in order to enable read caching on your drive.

Probably won't make too much of a performance difference, and like I said, I don't know if anybody's posted this yet, but it's worth a try... :)

do you have to regedit to get it. might be in admin tools/computer management/disk properties.

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Hardware Profiles\0001\System\CurrentControlSet\Enum\IDE

Then you choose the drive you want to change.Someone tell us if this helps or hurts anything.

My exact path is: HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Hardware Profiles\0001\System\CurrentControlSet\Enum\IDE\Di skWDC_WD800JB-00ETA0______________________77.07W77\4457572D414D4 C48353134303633003100000000\CurrentSettings
