Optimum percentage of ram usage

[mistake]

What is the optimum percentage for RAM usage?

 

[damasvara]

As low as possible...

But anything from 10-70% is normal. Reached 100%, then you'll need upgrade.

Are you referring the RAM usage or the amount of RAM to be installed for the PC?

Tnx Damasvara
i mean RAM usage.
My OS is
Core i5,2.26G,3M
4G DDR3
but my usage % with only a firefox & internet connection, not less than 50% also not more than 70% yet
is it normal?

Your OS is..... ?

How do you read the used memory? Which tool and which value/counter?

Can you start Task Manager (CTRL + SHIFT + ESC) and check for these values:

Cached
Available
Free

cashed 1659
available 1914
free 316

guess less than 80% is good.

This means that you are using about 2,1 GB out of your 4 GB. Excluding that another 1,6 GB is used for caching.

It is no problem really, but it could seem a little to high with 2 GB used with just OS loaded and Firefox running.

Tnx really for ur attention
is there anything that i should do?

 

[damasvara]

You're all good...

Only suspect lack of RAM issue if you're having lag issues or temporary freezing, which means you don't have the proper amount of RAM in your system.

FYI, my 2GB on XP works like a charm. I assume a 4GB on the 7 will perform even better.

So it seemed RAM capasity is more important than CPU Cache.
(in performance speed & less lack)

Hello guys! I just bought a new (second hand) CPU a Intel core 2 Duo E8500 wich runs at 3.16 Ghz and 6mb of cache (one of the best cpus that fit in an LGA 775 socket in my price bracket) and a brand new Nvidia GeForce GT730 GDDR3 with 128 bit. I had a Intel celron dual core with 2.6 Ghz and 1 mb of cache memory. I had 3 Gb DDR3 of RAM running at 1333 ghz. I am using it to play older games, mostly ETS 2 and Stalker but I am intrested in buying a new 8gb of RAM memory (single one). Right now my desktop gadget says that I use about 70% of the vailable RAM when playing but I also keep another window open because I like to listen something when i'm playing. Right now, with only a browser window open I have 1724 Mb of memory cached out of a total of 3071. Should I go for the upgrade or not, as I said, rarely goes over 75% RAM usage but CPU usage gets to 100% frequently. What should I do? Is it normal ( generaly I keep arownd 2-3 windows open when I'm playing but none the less the cpu usage is quite high anyway...) I hope you'll be able to help me because i am really confused.
