CPU & RAM Question.....

Wiggins · 25 May 2008 at 20:34

I currently have my E6320 at 3.2Ghz (470fsb) and my Corsair XMS2 is at 940mhz 5-4-4-13 (1:1).

Now if I drop the multi down to 6x and ramp the fsb to 500 giving me a 3Ghz clock on the CPU and 1000mhz 5-5-5-15 on the RAM, will I see more of a difference than my current setup in gaming, encoding at so on?

From what I've heard before (reading somewhere on Xtremesystem) there's almost no difference whatsoever. Encoding and possibly gaming depend very much on CPU (quad core + SSE instructions) and higher Ghz.

Thanks

I asked as I remember reading that the faster the memory, the more the C2D's loved it.

Just was not sure if it would work in my favour by dropping the speed of the CPU and ramping up the speed of the Memory.

Here you go:

Quoted: "For example, 9 X 400 MHz and 8 X 450 MHz both give you a CPU core speed of 3.6 GHz. All other things being equal (and they seldom are), you'd expect, using a good memory benchmark program, that running at 450 MHz would give you a 12% increase in memory bandwidth.

When I did it, I got about a 5% increase. With applications and games, I saw no noticeable improvement. Apparently memory performance does not scale linearly with FSB frequency at the high end. I'm not too surprised about games. I suspect that most modern video cards bottleneck around 3 - 3.2 GHz.

I suspect that's due to two factors. The Intel Core2 architecture is pretty efficient, and the large L2 caches help a lot.

The main thing I noticed was an increase in motherboard temps."
