Hardware reserved memory amount

I have a T400 and just noticed that I have 106MB of hardware reserved memory as reported by Win 7's Resource Monitor. I tried disabling the switchable graphics in BIOS and a few other tweaks but the amount stayed unchanged. I read that people usually see 0 - 5MB on computers from other manufacturers.

Do you see the same (or different) amount of hardware reserved memory on your machines?

 

X200T: 106MB (4GB / windows 7 enterprise x64)
X61s: 74MB (8GB / server 2008 R2 enterprise)
D10: 2MB (16GB / server 2008 R2 enterprise)

106MB is nothing.   if you have apps running out of memory, an extra 106MB won't save them.   i would file this in the "non-issue" category and worry about more important things.

 

Thanks for posting all your numbers. Still wonder if there is some hardware I don't really need that can be disabled in BIOS to free-up some of this "lost" memory. With 4GB it's really difficult for me to use it all up but getting ~100MB back for nothing would be nice.

BTW on a Win 7 x64 the WEI index for memory (for what it's worth) would be less than or equal to 5.9 if the available system memory is less than 4096MB.

 

hardware addresses are mapped whether something is enabled or disabled.   unless you're a whiz with machine code and writing a Phoenix NoteBIOS image, that 106MB is gone.   as it goes, there ain't no such thing as a free lunch.

admittedly, i'm still not clear on what the issue is here.   if you want higher WEI scores, just change the numbers in notepad.   my ThinkPads at that time all had 9.9s across the board the second day i installed beta copies of vista.   they were ahead of their time.   for what it's worth, WEI scores aren't worth much.

btw, isn't "WEI index" redundant... kinda like an "ATM machine"?

 

" an extra 106MB won't save them"

Erik. the proper anser is, it may or may not. A large version of my programs is 150 KB.

I also think the hardware configuration and BIOS have to do with the amount of reserved memory. This is why I asked to post others reserved memory amounts so that if someone is with a T400 we could have compared to see what is different in our configurations and get an idea what is "wasting" so much memory on our Thinkpads. As I wrote in my earlier post, most systems from other manufacturers tend to use way less reserved memory.

 

of course.   like i said, this stuff is mapped in the BIOS.   the only way to completely free those 106MB is to rewrite the BIOS and remove addresses to free up the space.   you'd be going to a lot of effort for a minuscule amount of memory.

you could try disabling unused ports in the BIOS to see if that helps.
