Opteron 170 HTT

Recommended Posts

Call me stupid for not noticing this a while ago, but I just noticed that the Opteron has a 1000 HTT where as my A64 3200+ had 2000. To calculate the HTT multi, you took the ddr speed (200x2=400) times the HTT multi (400x5[default]) = the HTT of 2000. Ever since I put the Opty in, I had never changed my HTT multi of 4 when I had my FSB @ 250x10. That would have given me an HTT of 2000 on what should have been only 1000. The processor was stable, and still is at 277x10 with a 3x multi. Should I be running the multi that high? That makes the current HTT 1662. I can drop it to 2 which should bring the HTT to 1108 at the current over clock. Could it be what is holding me back from 2800? Thanks in advance for any suggestions.

not sure if i have read this correctly but at a fsb of 277 with the ht multiplier at 3 the hypertransport bus speed will be 831 as long as u keep it below 1000 you will be fine.

 

this is a useful tool http://avala.yubc.net/~lukija/A64Info.rar

You probably saw it at Newegg. Don't worry. The HTT in 939 Opterons is 2000.

To avoid confusion,

 

The HTT BUS is actually only 1000Mhz.

Because this is also like a DDR based BUS some people say it is 2000Mhz.

 

Just remember that the true value is,

Base clock (FSB) x the HTT ratio.

Thanks for reassuring me I didnt screw something up. I just wanted to make sure I was understanding things correctly, and well, now I am sure. :)
