1600HTT vs 2000HTT

I have a 3700+ running at 2.7Ghz

Now the question is.... since I am running an A8V-MX my HTT is only 800x2 (1600Mts) but it is a 2000mts processor.

Does this factor realistically bottleneck the processors performance?

Not really considering the HT bus is used for communicating between processors. Since you have a system with 1 processor and it doesn't have a coherent HT link then it shouldn't have a performance hit at all. There should be an option in BIOS to be able to tweak it closer to 2000 (or 1000x2) though.

edit... Supposedly there is a some kind of hit if it is too low or over 2000 though.

The HT bus is used:
1-As a FSB (to transfer info in and out of the CPU from RAM).
2-To transfer info between CPU and other devices.
3-And optionally to link 2 or more CPUs (that's why only CPUs with more than one HTT bus can be linked togeather.

However, the performance hit from 2000 to 1600 is pretty minor, though by few percent, bandwidth and multitasking are visibly penalized, especially when you have a CPU thet supports 2000HTT on a chipset that outputs only 1600. That was my case, but with a slight overclock I got over that.
