HTT Question - Page 2

post #11 of 25
The HTT, HT (or LDT in DFI only) can be confusing.
The Mem Controler is available in 1-5x, utilize it x the HTT to get the 800-1000 factor.
Oh... yes 260x4=1040 which should be fine... beyond 260 drop to 3x

It was a bit of a challange at first ...
HTT and relative CPU effects and how it relates to the RAM's HTT factor.
Examp
HTT of CPU 250
RAM on a 1:1 the RAM HTT = 1250 with the default 5x Mem Multiplyer which would then require a reduction to 4x for an 1000MHz rate.
The divider will allow the RAMs speed more room to increase as you increase the CPU's HTT with RAM that can not match the CPUs HTT. Thus the need for 333 or 266 divider settings (re the Asus and others that do not have other measns of adjusting the dividers) where as some MBs have finer adjustments like the DFIs.

Since it hasn't been mentioned, keep in mind that your HyperTransport speed will have no impact on your system performance. The bus bandwidth is so high that your system won't be negatively impacted with a 800 mhz bus versus a 1 ghz bus, so there's no reason to try to push it.

Good catch... I usually forget that factor when relating to keep it in the 800-1000 range.

Where would I start noticing a decrease in system performance? Is there a certain bus speed that I should not go below? And also, could you try to elaborate a little more on why there would be no impact? It seems counterintuitive that this would be the case?

Picture this in your head....you're alone on the freeway driving along, would it matter to you if you had 5 or 6 lanes? Same thing with the HyperTransport Bus speed, it's overkill for your computer system. Lowering it from 1ghz won't make a difference. Is there a magic number to not go lower than? No,not really. Just keep it below 1ghz by using the next lower HTT multiplier as you raise your htt. To explain further, your system bottlenecks lay elsewhere in your system. Your computer can't sustain the use of a 1ghz HyperTransport Bus.

Lol that makes a lot of sense. Thanks for the analogy! One more thing about htt, could my pc probe really be that incorrect stating that my fsb is 952 when my multi is 3x with htt at 238? Is there another program that I could use? I have looked in CPU-Z and a few other programs with no luck.

Would these bottlenecks rest in such places as my memory? Using a higher rated module like ddr500, would this increase the likelihood my computer could sustain the use of a 1ghz HyperTransport Bus?

Trust your BIOS settings. If you physically change it to a 3x htt mult and set an htt of 238, you know what your system is running. It won't matter, but you can set it to 4X if it's bothering you. I'm running mine at 858 atm.
