FAQ: Will running ram at a faster speed give a performance boost?

post #1 of 4
Thread Starter 
Ok, the faq section seems to be down so I'm gonna post it here.

As you all probably know, there are 3 basic types of ddr ram:
pc2100, which is ddr266. this runs at 133mhz. It's made for a 400mhz front side bus

pc2700, which is ddr333. It runs at 166mhz. It's made for a 533mhz front side bus

pc3200, which is ddr400. It runs at 200mhz, and its made for an 800mhz front side bus.

pc4000 and up, which as someone else stated, I think it was yiffygriffy that pc3200 is the highest the jdec standard goes. This ram is high performance, and it just gives you more overclocking room for 800mhz fsb processors.


So, if you have a 533mhz fsb like mine, will running your ram at a higher speed, like 200mhz instead of 166 benefit you at all? Well your about to find out.

ok this is with my graphics card oced, and my processor oced to 2.4ghz, so I could get a 533mhz fsb. Its been like this for months so it really doesn't matter. Anyway you can see my score is 2469 marks. My ram is at 200mhz

http://www.rigshowcase.com/img/133IuL9R/1416

Here is when I oced my graphics card, oced my processor to 2.4ghz, and took my ram down to 166mhz. as you can see, absolutely no difference.

New stuff added here: SUPER PI SCREENS

with 200mhz ram, I get this:

with 166mhz ram, I get this:
http://www.rigshowcase.com/img/133IuL9R/1419

So, while you get a 1 sec difference in super pi, there really isn't a benefit of doing this. I did this about 3 times each, and got the same result each time. To get any better performance out of this ram, I'd have to adjust timings.

I hope this is helpful to anyone at all, this is my first faq. I'm open to suggestions, so if I need to change something, let me know.

Oh, and another thing, I have no idea if anyone made one similar to this, but if they did lemme know...I can get a mod to delete the thread.

well, you chose a bad benchmark, try Super PI (50% cpu speed, 50% memory speed).
And it is true that if your in a high OC and run your memory a little faster than your core speed, you will see a small preformance

will do, I just downloaded superpi right now
so what do I put to show the benchmark? a screenshot of superpi?

added super pi screenshots to it. I only got a 1 second difference between 200mhz and 166mhz. so, no real big difference.

Yes, you will see some additional bandwidth, from a RAM>CPU divider. See RAM101, I posted up some results of 1:1 compared to 3:4 (or 4:5, can't remember for sure, and too lazy to look for myself).
