I have my q6600 overclocked to 3.4GHz on my p45-ud3lr board. i was hoping to get my ram at a 1:1 ratio and cpuz reports it a 3:5. my multiplier is 425x8. is there any way to get my 1333 ram at a 1:1 ratio?what FSB would i have to use in order to keep my ram at 1333. no matter what i do my ram never shows at 1:1. my bios doesn't have an option for fsb:D ram ratio.

More about : q6600 ddr3 1333

one other thing. will this really effect my performance not keeping it at a 1:1 ratio?

You would need a fsb of 666.5 to run your ram at 1333 and a 1:1 ratio. That just isn't going to happen.

I would run your ram at the highest setting that is stable without over volting.

Or you can run with a fsb of 425, effectively running the ram at 850mhz and a 1:1 ratio.

I personally think that is an incredible waste of your ddr3's bandwidth.

So basically with ddr3 1333-1600 memory its almost impossible to get a 1:1 ratio with any CPU?

And with an fsb of 666 x 5 that seems to equal 3.3 and change. Why can't this happen?

You will not be able to reach that fsb on any mobo 450 to 500 is about the limit

I see. So I guess I have no choice but not to run at a 1:1 ratio. I have read so many different opinions on whether this will affect performance or not. I am actually running my memory at 1416 frequency with 7-7-7-20 timings. I do have one question about that which probably doesnt fit in this thread but I'll ask in anyway. My Row Refresh Recycle Time is reported at 74 Clocks in CPU-z by default. Is this really high or should i try to widdle it down, and how important is it? Thanks for all the responses.

It's a little high but that's normal with ddr3. You can try to tweak it down a little, just test for stability so not to Corrupt files. I would focus on the main timings first, and maybe try running in 1T.

For some reason when i enter 1 as my command rate in BIOS CPU-z still reports it as 2T. At default my BIOS says its at "0" auto. Any ideas?

I think that's true for just using DDR3 RAM with a Core2 CPU. I do not think that a Core2 CPU can take full advantage of DDR3's poetential.

I did read some benchmarks and with lower timings 7-7-7-20, it just barely beats ddr2 1067 with 5-5-5-15 timings. But i figure it is future proof, no?

"Future proof" is a null concept.

OK. So some time in the future, you have the possibility of moving your DDR3 RAM to a new platform, in essence rendering a quite nice, though technologically obsolete, computer inoperable. When you do move the RAM, it will probably be obsolete, the market having moved on to DDR4 or DDR3-3000 :)  or something.

haha, you are probably right, but say I need a new mobo one day and decide to grab an i5 or i7 along with it, my ddr3 will go right along with it and save me $90. Also, I have my ddr3 at 1417 frequency with 7-7-7-19, which according to benchmarks I saw does out perform ddr2 1066. So I don't believe I wasted my money.

By future proof , I think 1-2 years I should be ok with this ram.
