PCPER.com: 5 GHZ+ Phenom II Overclock on Dry Ice, 6Ghz on LN2

[Eson]

Who cares if its cherry picked or not? Its not like all these overclocking headlines from lan parties and such are not cherry picked Intel processors.
The most important point is that AMDs fastest processors are no longer as Intels slowest, but it might even compete with Intels most overclocked ones.

[informal]

I am impressed, my hopes and dreams are becoming a reality

But really, 1,9Volts? I think that is a little bit high. Wouldn't i7 be able to hit higher speeds at that voltage? Dont remember what voltages were given to i7 when they pushed it. Anyone remembers?

But otherwise, if u feed it 1,9Volts and it takes it with spactacular results, then for the love of PII, do it!

Intel and AMD 45nm gen chips react differently to vcore.Intel Core i7 at 1.9V reacts differently compared to Deneb at 1.9V.Deneb sits at default 1.35V and still has 75/95W envelope.This means that even 1.55V on Deneb is not that huge of a number for air/water. 1.7-1.9V for LN2 is not that extreme,for short time tests.

I agree on the pwm level of Am2/Am2+ boards. the asus 790fx sb750 had the highest 8+2 phase. the rest are all 4 or five and some have a +1.

Asus M3A32-MVP Deluxe(/WiFi-AP) is nothing but 4+1 phase...
...note that even Asus' marketing is clueless as they actually quote it as "8+2".

[Manicdan]

why do i get the feeling this cpu is gonna be hard to find and price is gonna be jacked up due to popularity. sure it might be around 300, but if the egg knew how much people wanted it, it could be much higher

He's talking about the sb750 board (aka M3A79T). It's an sb600 board you're linking here.

[Gendo]

If this is true it's amazing news! I've never really been an amd fan but they need a good cpufamily to get the competition with Intel going again. And competition means fighting to be cheapest. Which is good for us consumers

there almost identical, lol only difference is SB750 vs SB600 plus an extra heat sink and fan.

Whats the difference between the amount of phases? E.g. if I have 4-phase for CPU compared to 6, 8, 12 or 16 phase? Everything above 8 is marketting hype?

[Dami3n]

If prices are good, i probably build one of those Deneb with a Lanparty JR 790gx
Any idea of release date and prices?

[demonkevy666]

the difference is a pwm blowing when priming at 1.45 volt, and one not blowing ever at those volts.

just provides clean more stable power to the cpu for example run high overclock on a 680i and look at the OCCT chart for Core voltage it will be rippled all over the place with a respectable overclock now compare that to say the rampage extreme or the X48 T3RS where the chart is a solid line,
you can use less voltage to gain same overclock and be stable because the voltage is constant.

this is what ive noticed

So more phases, more evenly the load is balanced and "one phase" does not get such a big hit from high power draw by the CPU?

[wiak]

Can you get me one of these CPUs + motherboard for christmas?

+cpu -motherboard

AMD has kept the logo for the Dragon platform very quiet lately, but they recently posted pictures of a banner online that clearly shows the logo. For those that don't know about the Dragon platform it consists of a processor, motherboard chipset and graphics card that have been tuned to give you a better user experience. To be more specific the Dragon platform is a combination of an AMD Phenom II X4 processor, Radeon 4800 Graphics cards and an AMD 7 series chipset based motherboard. This platform is an update of the Spider platform that AMD launched a year ago to the month. The AMD Phenom II X4 processor is built using AMD's new 45nm process technology and as a result has 30-50% better power consumption and higher clock frequencies. If you haven't heard about the clock frequency improvements yet be sure to check out this article we posted yesterday afternoon.

i've heard of the i7's topping out and more voltage doesn't help clock scaling. was 6.3ghz seen in windows or a bootup screen like the 5.7ghz i7 was?

[Insanity]

Except the one he linked is 4+1 phases while the M3A79T is 8+2 phases.

If you mean 6.3 GHz for the Phenom II it was Crysis benchable, atleast as I read it.

oh really here a pic.



opps second one was 78 and not the 79.

[Insanity]

oh really here a pic.

My bad, after looking they're both 8+2 phases. Got lost because the guy I quoted first said the M2A32 had only 4+1.

SB600 is missing ACC, has no RAID5, slower USB 2.0 performace, from 2006
SB750 has AMDs Advanced Clock Calibration, RAID5, faster USB 2.0 performace, from 2008

the key here is Advanced Clock Calibration, that allows better overclocking on current 65nm agena cores and upcoming deneb cores!

some 790FX boards have SB750, allmost all 790GX boards have SB750

[Sparky]

oh really here a pic.

Uhm Asus says straight on their site it is 8+2 (what does the +2 mean?) and you can't see under the heatsink for anyone to say what it is, so I'm trusting that Asus knows what they are talking about

2 phases dedicated for the 8-phase CPU PWM.

I think You have a good point there

[doompc]

The 2 addition phases are exclusive for the internal northbridge (like the "uncore" part on Nehalem, the IMC and the L3 cache).

[informal]

Seems "someone" was spreading fud on the day AMD demoed high OCing capabilities of Deneb:
http://theovalich.wordpress.com/2008...re-i7-thunder/

During morning hours in US, I was contacted by several high-level executives who asked me is it true that AMD was sold to a private investor.
Timing of such rumor was without any doubt, pure FUD attack to steal the thunder from today’s announcement that got the press and enthusiasts tingly like elementary school girl.
The announcement is expiry of embargo on AMD’s Press Preview, held recently in Austin, Texas. Like I hinted in an article just days ago, AMD worked with selected hard-core overclockers to tune up the Phenom II CPU and Dragon platform (790GX chipset with AM3 socket, nothing earth-shattering here). The results are quite spectacular, to say the least.

Hm, "is it true that AMD was sold to a private investor." ."Someone" got some nice knee jerk reaction to the Deneb demo yesterday,were "they" worried?

edit:
More from Theo's post:

History of AMD and sub-zero cooling is quite interesting. AMD was the first manufacturer to showcase vapor chamber and liquid oxygen cooling (yes, oxygen, not nitrogen) with Athlon 550 MHz that reached 1.03 GHz and became the first CPU to pass the 1 GHz mark. As the time went by, AMD slowly started to move away from Swashbuckler attitude lead by Jerry Sanders and put a dull corporate Motorola face lead by Hector Jesus Ruiz. All of this is past now, since AMD put substantial effort to produce a CPU which operating temperature is massive 300 degrees Celsius!
Yes, you’ve read it correctly – from -200 to +100, you can be certain that your Phenom will not fail. On-die sensors are tweaked up and they will not lock the part at -100 or -20C, and you can use dry ice or LN2 to crank it up to the max.

Also interesting bit is AM3 940 version has 16GB/s of BW with DDR3-1333:

Phenom II comes out with 16 GB/s of memory bandwidth using only two channels, and clocking like there’s no tomorrow.

Correct. If the best components are used 4+1 is more than sufficient.
16 phase is marketing or inferior components. Or very, very expensive motherboards for no reason.
It's amazing how many people get sucked in by numbers on a box.

Note, the 6.3ghz @ 1.9v was done on a Gigabyte 790GP, no 16 phases there.
