AMD Shows Deneb (Phenom II) pictures of 6.2GHz CPUz etc

Just 20mhz on the HTT would add 620mhz to that...

If it's true - Who cares?!

I'm just saying, with the multi only being used, there's some room for some HTT tweaking, and with the multi being so high and as long as it budges a bit on the HTT then we're in for some fun to watch.

Yeah, from what I saw as well as after having a hands on play, I believe we'll see higher frequencies obtained by the OC elite with combinations of lower multipliers (than used by AMD @ the demo) and higher bus frequencies. Here's a snippet from a post I made on OCAU replying to dino on this point:

However, my comment in regards to the extreme clocking regulars doing better is based on the fact that the demonstration was done simply using the multiplier for frequency increases. This meant that the bus frequency was being left to 200MHz and simply multipliers applied at intervals of 0.5x were used for frequency increases.

From my play on the test beds provided (GIGABYTE motherboard and either OCZ Reaper or Corsair Dominator memory with Deneb ES + stock heatsink and rounded out by a HD4870X2) I found it much easier to gain additional CPU frequency by lowering the HTT multi by one and then increasing the HT bus frequency as well as the CPU multiplier.

So in terms of this overclocking information being information that was shown to me or told to me by AMD, it's actually information that was obtained through observation and use - also out of all the media there I was the only one with sub-zero experience/knowledge and therefore a lot of information was obtained just quietly chatting with the guys responsible for the demo both before, during and afterwards. I've got further info like voltages used for what frequencies but that's currently NDA covered - well, the frequencies are but they got up to using 1.95v dropping to 1.936v and didn't go above 2v due to blowing caps on the motherboard (already sent some emails regarding this so hopefully a revision on it's way).

Also on this note, all the media were getting stuck at ~3.9GHz because they were only using multiplier while with a combination of settings I hit 4.1GHz with minimal effort. This further adds weight to the concept that the chips have potential to go further in the hands of experienced overclockers using combinations of settings.

An interesting side note: The maximum multiplier available is currently 48x so there's plenty of multiplier headroom

can i ask you to confirm again what you stated... you did the oc on stock cooling????

I believe in a lot of things, but I am supposed to believe in that picture? Why?
I mean I am getting Phenom 2 as soon as it comes out no matter what, but how do I know this picture is valid?

Because people who were at the event say it is valid?

Hey seeing as you were there, how many systems were running OC'ed? Was it just one running as all the cherry picker comments seem to imply?

Also did you actually see the systems running at the claimed speed for more than a suicide shot?

If its anything like the current phenom then HTT overclocking is useless. Performance is identicle between high HTT and high multi oc in my experience. Quite a few people find they overclock higher using just the multi. High multi + high nb clocks > HTT any day of the week.

I can't wait for one of these! Very happy with my current phenom, I'm really hopin for 4ghz+ on water
