SPECCY SUMMARY



AND SPECCY RAM:



ALSO,
shouldnt i see even more memory, since my video card also has 4gb memory?

 

ok thnks!.
that actually brings me to another question.
i dont know if i should make a new thread for it or not though.
basically, ive only used an old computer up till now, with no extra features, so ive always kept my startup items down to very little, but with this new computer i dont know which of the startup items are nescesary for best computer performance.
in other words, there all these programs like:

INTEL RAPID STORAGE TECHNOLOGY (will the computer actually run slower if this doesnt turn on on startup)
INTEL HD GRAPHICS (will the graphics not be to their full potential if this doesnt turn on on startup?)
DELL TOUCHPAD (will the touchpad and multi gesture features not work correctly if this doesnt go on on startup)?
DELL AUDIO (it has maxx audio speaker enhancment settings) will the speaker enhancment not go on if this doesnt go at startup?

so with all these things, will they not turn on if i disable them at startup, or will thye be on always?

if i should make a seperate topic for this, let me know.

 

IntelRST is only needed if you have RAID or an SSD caching drive, both scenarios are relatively rare. Windows can operate normal JBOD drives like your SSD single drive fine without it and there would be two fewer drivers loading up at every boot.

Here are a couple of methods to uninstall it and set up your default Windows drivers instead, should you want to do so.

 

The ram on your video card is not available as system memory; it is attached to the GPU for graphics usage. But; that PC uses hybrid video technology and will dynamically switch to the ATI video when the system thinks you are using a high demand video application.
Personally, I very much like Winpatrol for disabling startup items (right-click, disable in Winpatrol) and have used it for almost 15 years now. You can Google the Command entry for what it lists and know quickly whether you need it or not.

 

Hey, Davis, WinPatrol is only recommended way I've come across of modifying which itns are loaded at boot-up. Are there others ?

Often when I install a program it creates a start up entry and now my systems are full of junk that auto load when I boot up....

Yes, I have tried several different programs; WinPatrol is the best.

 

Autoruns gives the most control over startup entries, right-click menu items, etc.

 

Yes it does; but, it is far more difficult than WinPatrol if you make a mistake.

 

There's also StartUpLite and StartupCPL.

Some HowTo's on Autoruns are out there, here's one.
