Hey guys, I started to randomly start reading about memory speeds, and started reading up on the cpu:dram ratio. After reading for a few minutes, I was totally confused. In CPU-z it says I have a 1:2 ratio.

I just want to know if I should be trying to get this to a 1:1 ratio, and if so, how do I go abouts doing that.

I have a nice rig, and it works flawlessly, as stable as a house right now. I just dont know if I'm running it as optimally as I should be.

CPU = Intel q6600 @ 2.4ghz
mobo = Gigabyte EP43T-UD3L
Ram = Corsair XMS3 4x4GB (16GB total) DDR3 RAM - PC10666, 1333MHz

Any guidance is appreciated.

I'm not an expert here, someone may correct me generalizing...but I say you are fine being at 1:2 because you get that much extra room in case you overclock your fsb

Your Q6600 stock has 1066 Bus so it will be running at 266MHz FSB (266*9=2.4ghz), that means with a 1:1 memory multiplier your RAM would be running at 266x2 = 533 at DDR-533 speeds well below DDR-1333 (667*2) speeds.

Well, I don't want to run my ram at a slower speed... so to get a proper 1:1 ratio, I can set my cpu FSB to 333 (I got 333 by dividing 667/2) that should get my cpu up to approximately 3.0Ghz (333x9 = 3.0Ghz), would make my cpu match the speed of my ram?

Thanks for your info Deadrum

If you have the overclock knowledge, and proper cooling I'd say i cant argue with your math or logic. Its a little bit trickier than just bumping up the fsb. I dont know how comfortable you are with all that so i say keep a close monitor on all voltages and temperatures while you experiment.
