Still need to get me an AMD setup again. Must find time and money!

Thanks guys.

Believe this chip is a good one esp in comparison to others I've seen with their speeds vs voltage used to get there. I've noticed several chips needing 1.5v just to hit 3900MHz according to a chart I've been looking at.
Check it out here:

The speed I hit was right on par with most chips listed in the "Suicide Run" heading of this chart with alot less voltage used for that clockspeed.

If I can get my cooling squared away properly, may be able to do alot more here with it. I've already noted this chip is sensitive to heat in a big way and my current cooling is the biggest factor holding me back right now.

Charts like those help AMD noobs like me compare the pwnage, thx Bones, ur doing great and so is that chip.

Thanks Supes and still learning this system as a whole but it's coming along. Charts can give you an idea of what to expect on average.

It's good my chip appears to be better than most so far and eventual benching will tell the real story.

If I'm lookin at the right chip on the bot, it looks like 1.46vCore for 4ghz on the better than average chips.

If that's right, maybe this one is a "Golden" chip but even with the way it does with lower voltage, no guarantees yet.
I've seen and had chips that responded very well to voltage, scaled wonderfully - Then hit the wall and woudn't go further for some reason, no matter what was tried.
Hoping this one won't behave like that.

Kal-EL 07-20-2009 10:30 AM

Well, the tendancy is that the hotter (leaky voltage chips) tend to clock higher and scale higher under frostyness than the well behaved voltage/temp/clock chips.

Bones 07-20-2009 11:07 AM

All I can hope for is maybe this one has a bit of a mean-streak in it somewhere.

Only one way to find out....

Still have work to do here (Never ends does it?) and looks like I may have hit the wall for now.
Not bad for something on air but I know it could be better. Supes, looks like you hit the nail on the head as to how this chip behaves "As Is" but I know there's more somewhere in there. It's now a matter of finding it.

Believe setting it up with WC'ing is the only way to get more speed from it at this point in the game. I did note a real spike in temps once speeds got above 4.0 and that has to be the issue here with it.

Get temps down and speeds up is the mission here. :wh2:

However I do like the MHz speeds I've been getting from my RAM with the timings used. Still have work to do there as well and know I had the timings really tight with these runs.

Looks liek the new 720s reall open up on am3 motherboards. I may have to grab one to see if my 550 performs any better with ddr3.
