The Hypertransport-link on an Athlon 64 3500+ processor runs at a physical
clockspeed of 1000MHz.
Since Hypertransport uses a DDR-(Double Data Rate) technology, it is capable of transferring two
packets of data in a single
clock-cycle which results in an effective
'clockspeed' of 2000MHz.
Basically, 1000MHz = 2000MHz in this case. ALWAYS, regardless of what motherboard or chipset you're on - they all support it (as long as we're talking about an 939-pin Athlon 64 processor's HT-link, of course ).
It's just like with DDR-memory: While PC3200/DDR400 memory has an effective
'clockspeed' of 400MHz (obviously), it actually runs at a physical
clockspeed of only 200MHz
Due to its DDR-technology, it can transfer as much data per clock-cycle as a (theoretical!!
SDR-(Single Data Rate, one
packet of data per clock-cycle) SDRAM running at 400MHz - hence the 'effective'
