About ram to fsb ratio.

post #1 of 21
Thread Starter 
I heard from ppl that own the i series of hardware that there's no 1:1 ram to fsb ratio anymore.

Seems that they prefer higher ram speed to the cpu speed.


I'm using the lga 775 chipset and at that time i always read from forums that the 1:1 ratio is the best.


Is this true? If it's true why isn't it implemented in the i series?


I'm asking this cos i have 2 OC profiles that seem the best for my system.

I own a DFI DKx48 t2rs mobo and a E8400 c2d. My rams are team xtreme 1066 rams.

First OC profile is 1:1 Divider at 400/800 Rams run at 930 amd fsb at 465 x9 = 4.18ghz. rams at 930mhz.

2nd profile Oc speed is reduced. No divider. . Fsb is at 450 rams run at 1081mhz. From cpu-z the fsb to ram ratio is 5:6. CPU speed is at 4.05ghz while ram runs much higher at 1081mhz.


Which profile has the higher performance? What type of benchmarks should i use to see which one performs better?

You can use for example MaxxMem or memory and cache benchmark of Everest Ultimate.

I just ran the resident evil 5 bench

The first one is 1:1 ratio higher cpu speed lower ram speed





2nd one lower cpu speed 4.05ghz ram speed 1081mhz

Using everest i did bench it before as you can see some numbers are higher while others are lower










To summarize it for those that cannot read, as seen in the 2 pictures. The one with the higher ram speed had a higher score obviously but scored lower on the L1 and L2 cache categories compared to the one with the lower ram speed at 1:1 ratio.

So it seems that the lower Trd the better and from the pictures i posted the lower fsb but higher mem has the lower trd.

a) offering a comparison
b) fill in your system specs so those of us that do read would be of more help
