Someone please exlpain this HTT lark to me...

[[SKR]Abe]

I have a shuttle SN85G4 with an AMD64 XP3000+

What difference, if any does changing the HTT to x3, x4, x5 ?

Does it make a difference in everyday use ?

The shuttle wont boot if I select x5.

I dont know what it does but say x5 will let you hit 200-250fsb, x4 240fsb - 260fsb and so on.
The reason it wont boot on x5 may be if you have overclocked.

nothing is overclocked at all in my system.

The shuttle manual explains nothing about HTT.

Google throws me a load of pages that go right over my head

I just need someone to explain it REAL slow !

The HTT is the link between the processor and the motherboard chipset. In socket 754 systems, this was 800mhz (1600mhz) which is the 4x option. In socket 939 systems, this was increased to 1000mhz (2000mhz) as the 5x option. As you can see, the multiplier option correlates with the processors FSB speed. So when you overclock the FSB (to increase the speed at which the processor communicates with the RAM), the link between the motherboard chipset and CPU is also overclocked. So to avoid this being the stumbling block when overclocking, it's usually best to drop the HTT to a lower setting. Doing so has literally no effect on the overall speed of the system because the link is already much faster than it needs to be.
