Good A64 HTT Stress test?

Just curious, what's a good stress test of the HTT (FSB) on a A64 Motherboard?

I'm trying to find my max HTT and so far I can boot up at 310mhz and run prime, but apparently prime's In Place Large FFTs is not a good test of this.
 
Since your HTT should not exceed 1000 "3" is your magic number. If you can't rum prime at 3 back things (your ram speed) down. Prime is still the best stress test.

In your case 4 will put you over 1000 and "A" buys you nothing speed wise and "B" will become ustable real fast as a rule.

Thanks for the reply, but that didn't answer my question. I'm not looking at the Hyper Transport final speed (LDT x HTT speed). I'm looking at the base clock chipset speed (ie HTT/FSB). I want something to stress out my chipset to know that 310mhz HTT/FSB is stable.
 
What Bill is trying to say is, follow the stickied guide , run prime95 small fft's, and keep bumping up htt/fsb until you get an error,lock up, or reboot. Then back down 10-15mhz and its a matter of trial n error to find that sweet spot that is stable/fastest overall.

Basically, if prime95 isnt stressing 310mhz , bump up htt some more. :p

I'll give that Small FFT's a try tomorrow. The thing is my system actually doesn't boot at anything above 310mhz. So I'm wondering why it can pass prime at large FFT's for so long but not boot any higher. I'll see how the small fft's go though. Thanks!
 
Then try a small bump in vcore, that should be enough to get you to boot, and continue finding your max htt...and don't thank me, thank eclipse and the rest of the guys for making an excellent a64 oc guide :cool:
 
Well i ran two instances of prime. One using Small FFT, one using In Place FFT and they both ran overnight fine at 335mhz HTT/FSB. That's stable then?

Yup, I'd call that stable, at least math wise. I'd run some other programs, play some games etc. just to check it out a bit more, but it all sounds good at the moment.

Luck ;)

Woot! i'm going to transition the board and CPU into my main system tonight. Going to CS:S a bit and see how that goes. Hopefully I'll hit my goal of 2.8ghz :)

I disagree. I say run each instance by itself for 24 hrs straight - now that's stable.
