Windows Experience Index for RAM Decreased after upgrade to 64 bit

[mothkuri]

Hello everyone,

I just upgraded from windows 7 ultimate sp1 32 bit to windows 7 ultimate sp1 64 bit as the 32 bit is just using 3.4GB out of my 4GB available memory.

In my 32bit OS, windows experience index for RAM was 7.1 out of 7.9, but after 64bit upgrade it has gone down to 5.9 out of 7.9. What could have gone wrong here? All the other ratings were almost same.

I'm attaching the screenshots of the same.

mothkuri, welcome to the forums.

wei scores are subjective. Apply all updates for your motherboard as well as windows updates. Run the assessment again. Check your bios settings. Try running from the command prompt as administrator "winsat mem". Check this thread.

Hi there
Quality of memory chips / speed etc. Also if the memory chips are not identical the performance will be based on the set with LOWEST spec.

Note also don't run the assessment with anything else running - and it's best also NOT to run the assessment immediately after installing the OS - but to wait until you've booted up and used the system a few times.

Windows 7 (and Windows 8) do quite a bit of optimisation -- they try and "Learn" how you use the system and there's all sorts of algorithms in the OS to try and optimise the OS for YOUR individual use - based on how it thinks you use the machine. This takes a few attempts before it settles down so you may well find that the OS performs slightly more sluggishly initially than after a few days.

Technically this is known as "Pre-fetching" so what the OS attempts to do is based on the history of your usage it will try and load parts of the applications it thinks you use a lot into the system areas --this really does speed up the OS but it takes a little while before the OS can build up a reliable History Data base of your usage.

(Note - after a LONG time the OS can get sluggish again but that's due to all sorts of possibilities - installing / uninstalling loads of applications, temporary system files all over the place, disk defragmentation etc. The OS will probably be at peak efficiency after about 5 or 6 boots from initial CLEAN install).

Usually I wouldn't bother about these ratings in any case -- the only one that seriously matters is HDD performance which will KILL a system if it's bad even if you had an i7 processor in it.

Great information jimbo! I was also thinking that since 32-bit maxes out at about 4GB of RAM, you can add much more RAM to the 64-bit therefore making the the max rating of 7.9 harder to reach. I haven't had any experience with my rating changing like that so I don't really know but just a guess.
