Virtual Memory is made of RAM + pagefile (HDD)
Pagefile is not RAM, its just a portion of hdd being used as RAM and they will swap content from time to time with RAM.
The one that making the lag is when swapping the content from pagefile to RAM, due to the slow hdd + hdd always being used for other activity, in this case, memory boost dedicated a thumbdrive/SD card to do that job, hence they should give better performance than a busy hdd in handling the swapping of the pagefile because the thumbdrive/SD card just need to take care one job(pagefile).

More ram is better, but still, there are some application insist on using pagefile even if you have a lot of ram left.

As explained before, Virtual Memory is RAM + Pagefile..
Which on the attachment, its the max size for PF Usage or you can see on the Commit Charge 2598M/3412M
That's coming from 3GB RAM + 512MB pagefile = 3412MB Virtual Memory (3GB is roughly around 29xxMB)


As for what the need of those, basically its RAM, just that one is slower and one is much faster.
And how it will be applicable, that's being handled by the OS or by the programmer, we the user, pretty much can't do anything with it.

The one being set aside in HDD is what being called as pagefile...
In this case, I reduced it to 512MB only...

As for Windows 7, not really familiar with it, even on the Task Manager, Performance tab, not showing about PF Usage?
or you check from dxdiag, add the number on Pagefile
VMemory = Used + Available

Need to wait when I get my hand on Windows 7 XD

Turbo Boost means overclocking a partial of its core to higher speed while shutdowning the other core IF the temp is still within fine range.
And we can't control it, the CPU will control itself.

Just some folding@home and some usual stuff, browser, music player, messenger, etc. Everyday is like this


for i7 quad core, Turbo Boost will shutdown two core to overclock the other two core to a certain clocks or shutdown three core and overclock the remaining one core depending on the thread for the application and if the temperature is applicable...
While for i5, i7 dual core, its will just shutdown one core and overclock the other remaining core.
i3 doesn't have Turbo Boost.
e.g. i7 720QM 1.6GHz will run 1.6GHz for 4 cores or 2.6GHz for 2 cores or 2.8GHz for 1 core.
i5 520M 2.4GHz will run 2.4GHz for 2 cores or 2.93GHz for 1 core.

Well, it mostly depends on your application whether he can utilize the extra cores or not.
The main thing is optimization, the same thing with HyperThreading which also introduced in the Core i-series.

As for
Imagine 4 ppl with moderate working speed VERSUS 1 ppl of fast working speed.
Yes, its feasible, if only the working can be done parallel, if not? They would be waiting one of them to finish first and let the next person to continue it.

Well, this is assuming discussing 4 persons vs 1 person doing 1 job at one time(since this is how computer works). If you meant 4 persons vs 1 person doing a lot of different jobs, then yes, you are right.

Since the Turbo Boost works depending on the applications. If it support 4 cores, then it run at 1.6ghz, if only support 2 cores, then it runs at 2.6Ghz and so on...

Possible, just need to get the Windows 7 disc...

No more in production...
