Ldt @ 2x


Recommended Posts

After much reading from here and from others, this new thing of LDT and HTT is quite understood well now.

 

But I need to be sure and I do not base only on reading posts. Today I began making some mathematics on this boogie thing and all is very easy to understand.

 

HTT = LDT x FSB so:

 

800HTT (1600DDR) = 4xLDT X 200FSB and

600HTT (1200DDR) = 3xLDT X 200FSB

 

The same thing of course has to happen on all fsb frequencies between (200-450Mhz) and on all LDT multipliers (1x-5x)

 

So making another example, let say @ 300Mhz fsb

 

900HTT (1800DDR) = 3xLDT X 300FSB

600HTT (1200DDR) = 2xLDT X 300FSB so far so good

 

Now let's just do another example but instead we include the cpu multi aswell.

Let's keep on the same and putting a multi of 4X on processor

 

900HTT (1800DDR) = 3xLDT X 300FSB AND CPUMulti 4x X 300FSB = 1200MHz

600HTT (1800DDR) = 2xLDT X 300FSB AND CPUMulti 4x X 300FSB = 800MHz ????????? Hoy hoy wtf the LDT doesn't has to lower cpu frequency so why it lowered it by 400MHZ.

 

Did I loose you yet?

 

OR a bug on bios 711 or bug from mainboard or something we don't know about LDT @ 2X.

Strange...and beyond me.

when I was trying to get my Patriot TCCD to 250x9.5 I got DDR430 whereas the 10x250 resulted in DDR500.

 

I was running 1:1 the entire time and confused as to my a divider seemed to be imposed when switching the cpu multi.....:eek2:

I guess it should be 237mhz (ddr474), not ddr430. Because if you are using a 9.5 multiplier, the "ddr400" memory divider will use the next upper entire value which is 10.

using a 5/6 divider every program reported 203mhz memory clock when is was 208.

the only program that reported it correctly was Ntune.
