How much does RAM affect system speed?

post #1 of 5
Thread Starter 
As you can see from my profile, I have an E6600 overclocked to 3.2ghz, but my DDR2 667 is underclocked to 645mhz (they're corsair valueselects, and I'm convinced they're holding my system back).

So how much will upgrading my RAM to higher speeds, say 1:1 711mhz, or even higher, affect the performance of my overall system? I'm thinking more in terms of FPS in games.

I want higher FPS, but I'm not sure I'm ready to shell out $250 - $300 on RAM when I also have my x850xt I want to upgrade eventually.

well, running at less than 1:1 will definitely hold you back. value selects aren't the best RAM. getting a good set of ddr2 800 sticks will definitely help you out.

hmph. If you want cheap but high-quality RAM, I'd go with GEIL or Patriot. They're companies that have proven themselves time and again.

I haven't been in the market for a LONG time, so I do not know which RAM you should get, but the companies I mentioned above are, IMO, excellent.

Now, as you may know, 1:1 ratio (FSB : RAM) is the representation of the "communication" speed between your CPU and RAM. Setting the ratio at 1:1 will maximize youre performance, let alone having one of the best rigs on your block.

btw, you got a nice rig. lol.

na man, at the low end i would go with some gskill or something similer, its jst nowadays you cant hardly get decent ram at below 250 well atleast 2x1gb kits anyways

well if your satisfied with your oc for now a new vidcard will get you the most p[erformance boost that is noticable i would do that then the ram later if your strapped for cash right now

If your gaming it doesn't affect your FPS much. For gaming and things its more about quantity than quality and 2gb is enough. High quality ram just allows you to overclock higher.

For more FPS the best upgrade is the GPU because with a conroe unless you have like SLI 8800gtxs the GPU is the bottleneck.
