effect of HT LINK SPEED on performance - myth or reality???

[hat]

here it is at 242MHz or DDR484, again SuperPI 1m

2420MT/s: 31.000s
1936MT/s: 31.063s
1452MT/s: 31.703s
968MT/s: 31.844s
484MT/s: 31.219s

and there we go - keep it above your ram speed for best results.

Not really. As I said you asked me to run my RAM at DDR484, and at a lower RAM speed the test was more adversly affected with every drop in HTT speed. So that test really proves only that SuperPi is more RAM influecned than HTT speed influenced, which we all knew/assumed anyway. It doesn't have a noticible impact on gaming, only benching, so who cares, really...

wow @ 5 people viewing this lol

the scores are lower on the lower ram speed - but there isnt much change between the tests on the lower ram speed.

Yeah, not much change to be concerned about, if you're trying to break a world record...

But right now, if you were trying to break a world record:
1. You wouldn't be using AMD anyway
2. You wouldn't be running your RAM at DDR484
3. You wouldn't be dropping your HTT link like that in the first place if you were dumb enough to try to use AMD to break a world record... again!

Not a myth. Overclock depends of many things and one of them is a stable voltage setting. If you don't have enough the devices will not operate at that frequency. Another biggy is cooling.

I recently overclocked my AMD Phenom II 555 x2 3.2GHz to 4GHz. I set the multiplier to 20 and went with it. It was unstable. I bumped the voltage from 1.4v to 1.45v. Still unstable. Then I bumped the voltage from 1.45v to 1.5v. It was still not stable yet. I bumped a little more to 1.525v. Rock solid stable.

Now it was time to set my Mushkin blackline ram up to 1600MHz from 1333MHz. It was stable for the most part at the stock voltage of 1.6v. I bumped the voltage to 1.63v and now that is stable.

It seemed weird but when I would boot and all the apps were loading like my system would choke. At least until everything was loaded. It took forever. So I examined the HT Link Speed. I raised it from 2000HMz to 2200MHz. It was like a flood gate opened and let the data through.
