How Much RAM Do You Really Need?

Battlefield 2, Continued

In our demo, slightly less than 1,500 frames are rendered, and in the graph above we've taken the value for each and every frame and displayed it as a line. This really shows you the impact of having insufficient system memory while playing a game using a lot of big textures. As you can clearly see, the green line which represents 2 GB system memory shows some variance, but compared to the blue 512 MB line, it looks almost flat.

As the graph shows; with insufficient system memory, your computer will have to access the hard drive a lot, and that will severely hurt the game play. The absolutely worst part is all these deep dips - they will really hurt your aim and reaction time.

Just to show you one more example, we took the data for each frame from the graph before, and sorted it in ascending order. You will notice that on the right side of the graph, the lines look almost the same. But what's really of interest for us is the left part. With 2 GB system memory, the game performance is for the most part kept above 60 FPS. Only 2.3% of all 1500 frames are rendered with a lower speed than that, which of course results in very smooth game play. With 512 MB, however, you see that a huge 25.8% of the demo drops below 60 FPS, which is far from ideal.

    I am a little confused as to what ram would work better with the Asus P5KPL-CM motherboard running intel E5200 CPU. I will not be gaming.I know I can use up to 3.5 Gbs of ram on my Windows XP 32 bit OS.The question is which would perform better> 2x1Gb ddr2-800 pc2 6400 or ddr2-667 pc2-5300?

    I use a Mac and a windows computer from IBM. I use the mac most of the time... it has 768 megabytes of ram.
    The Mac is a powerbook G4.
    Applications do crash but I like to do things quickly so that's why. With the IBM (Netvista), I don't use it that much, but sometimes I control it through RDC. The "Netvista" has 1 Gigabyte of ram.
    I don't really mind about the computers and the ram-I just care about that I can use them and that they don't crash each time I play a game.

    I've got 12 gB of RAM and I still experience slowdowns. Today it was due to numerous programs reading my hard drive - and even the RAID 5 array didn't help.

    Performance is achieved by striking a good balance between RAM, CPU, Hard disks, and the mobo.
  • my 256mb ram pc is working surprisingly take 2 minutes to load while my laptop got 2 gb ram and takes like 5mins to start 256mb ram system has been (like you were saying) balanced to do tasks throughout the system that are necessary only and working amazingly well.
