Trying to understand AMD HyperTransport 3.0.
I have a Phenom II X4 965 and an 890GX mainboard with HT 3.0. I've never OC'd before and I was messing around with the HT link speed and found that it seems to be capped at 2200Mhz.
I have the NB and HT link both set to 2600, but it still won't go past 2200Mhz. I'm pretty sure I'm missing something simple, but despite my Googleing effort I can't seem to find a solution besides raising the FSB. My bios lead me to believe that I may be messing up some special ratio.

Well...
There is really not much benefit messing with the HT Link speed, it is not like the old FSB where it bottlenecks the system. The CPU North bridge (IMC) on the other hand is where you really want it max out, since the L3 on a K10.5 is clocked at NB bridge and it also improves memory performance. Many boards have stability when OCing the HT Link anyways. If you really want to OC the HT-Link try adding some voltage on it.

So when you set the HTT link to 2600 it reverts back to 2200? Try a bios update yet?

i didn't update yet, but it's not listed as an issue on ASUS's site.

Do it anyways as it sounds like a bios issue either way. Technically you should be able to run a 2600 htt without adjusting voltage on the htt link.

Well it depends if the bus speed is set to 220 then the HT link speed won't go any higher than 2200mhz as it is set at 10x bus speed.
That should be right if i'm not mistaken. |

Is it the same for BE procs? Edit: Oh wait, that 9850 you have is a BE right?

You've got a BE, raising the multi might also increase the HT Link but let somebody else confirm that, but rasing the CPU bus will definitely increase the HT link! Use CPU-Z to see the actual and current speeds in which the HT Link is operating. But as others have said the HT Link doesnt increase performance much, worry about overclocking your CPU's clock speed and memory to the max first. |
