    Posted: 12 Mar 2009 at 11:40am
Hi, I was wondering whether speed or amount is more important when it comes to RAM and gaming. Is DDR2 800 @ 400 MHz pretty mediocre?
 
I believe there was a DS article about which aspects of the computer are important for gaming, but I can't find it.

If you don't have enough memory for your game, then getting more memory is easily the most important thing to do. For example, if you only have 1 GB, then getting more memory is the most important step.

However, once you have enough memory, getting more generally won't help. For example, there is no point in going from 6 GB to 12 GB for gaming. It won't help at all. In that case, getting faster memory would be your priority.

I have 8 gigs of DDR2 800 at 400 MHz, as well as a q9300 and a 9800 GT.
 
I am trying to figure out what the biggest bottlenecks are in my system. If my RAM was twice as fast, would I get a considerably faster framerate in Crysis?

Probably not. You would probably be better off upgrading your video card if anything.

You might want to think about upgrading your ram though.. 400mhz is pretty slow...

he has 800MHz ram either he is reading the bios which shows it as 400 x 2 = 800 or he needs to adjust his speed correctly.

It could very well be downclocked if its set to default.. For ddr2 800mhz isn't bad at all..

hmm, in CPU-z it says
 
in Memory: DRAM Frequency 400 MHz
 
in SPD: Max Bandwidth PC2-6400 (400 MHz)
 
I'm not sure why it doesn't seem to say 800 anywhere.

Since its ddr2 you have to take 400x2 and you get 800.. Your all set buddy! Just make sure in the bios your mem is running at 800mhz.

pc6400 ÷ 8 = 800

so your ram is 800MHz

You always know what ram speed you have from the "PC number" take that number divide it by 8 and you have your ram speed.

Why was this recommended? Just in case for some reason the RAM was set to run at a low speed?

faster ram = speed

more ram = more multitasking

If your 4GB is enough to do your multitasking now then you will gain nothing by adding more ram, if you increase your ram speed you will see very little performance if any.

With 1333MHz ram, you got good timings and good speed, you won't gain nothing from any ram upgrade, as a matter of fact if you get faster ram with slower timing you may hurt your performance.
