Useful to change memory settings?

I've never got very familiar playing around with memory settings or overclocking but now I am wondering if I would get any significant performance gain by changing some settings.

I have a Phenom II X4 940 processor, an Asus M3A79-T motherboard and 4 Gb Kingston ram @800 Mhz (KHX6400D2K2/4G).

The memory is running at 334,5 Mhz with stock timings of 5-5-5-15.
FSB-DRAM ratio is 3:5.

Are these settings ok? I am not looking to squeeze the max out of it but if I would be able to really boost the performance then I'm interested to hear this of course :-)

Hi newcomer and welcome to the Tom's hardware forum.

U can set the FBS-DRAM to 1:2 and the same settings 5-5-5-15 @ 1.85V

And ur CPU runs @ 800 @1.008V because u have enable Cool'n'quite.

Thanks! Which settings in the BIOS would I need to change to have the 1:2 ratio? Never done that before (will google too).

Does it make sense to turn off Cool 'n quite ? I have a Scythe Mugen cpu cooler so overheating should not be an issue.

this is very similar to the BIOS f ur mobo. Can u see the "Memory configuration" and "DRAM timing configuration"?, there u change the specs.

The cool'n'quite is used mostly for safe power when ur rig is in idle and u can disable it without problems.

I can get to the screen alright but I have no clue about the new values, and I'm not sure what I need to change into what - I'm a complete n00b as to the memory tweaking :D 

But I did disable cool 'n' quite and this makes a huge difference. Overall performance is much better now and the cpu core is running at 3000 Mhz instead of 800 Mhz. So I'm not even sure anymore if changing the memory settings would give me a significant performance increase.
