Hello,

I've an new Lenovo W500 with Vista 64 SP2 and 4GB RAM. After reboot memory footprint is very high with about 1.4GB in Taskmanager. When I look at the processes and sum that up briefly I don't see 1.4GB memory usage.

Any ideas?
Is this normal on Vista 64 SP2?

Thnx.

Wiesl

Wiesl,

I understand it is normal and not necessarily a bad thing. See this explanation of Vista's SuperFetch memory cache. It is possible, though not recommended, to disable it to get back your RAM.

This also implies that with SuperFetch turned on, the memory gauge in Task Manager isn't a very good indicator of a memory shortfall. I would guess that the Hard Faults graph in Resource Monitor would be better, though I don't have a feel for what the danger threshold is.

Hope that helps,
Dave

I've already disabled SuperFetch, ReadyBoost, Windows Defender, Windows Search to make Vista usable at all. The data discussed above was already with these services disabled (and rebooted).

Any other ideas where the high memory footprint might come from ?

Thnx.
