AMD finally seems to have put a realistic assessment of its processors, with its claims of the Phenom II X4 having "massive headroom" with its overclocking potential being validated once again, this time by Team Finland, at a CES overclocking event. Team Finland was able to overclock a Phenom II X4 940 processor at its highest stable clock speed of 6.30 GHz using extreme cooling. Earlier attempts to overclock the chip beyond the 6 GHz mark only yielded in test-beds that were able to POST, boot and display the clock speed using CPU-Z. This attempt however, was a benchmark-stable overclocking feat.
The bench consisted of a Phenom II X4 engineering sample, DFI LANParty Dark 790FXB-M2RS, OCZ DDR2-1066 memory, two Radeon HD 4870 X2 graphics cards in CrossfireX and Windows XP. The CPU cooling employed was liquid helium, which dropped the temperature to -242 degrees Celsius. To achieve a clock speed of 6.30 GHz, the processor's vCore was set at 1.84V, its bus speed at 280 MHz and a multiplier of 22.5 was set. The HyperTransport frequency multiplier was set at 8. The Radeon HD 4870 X2 accelerators were set at 800 MHz (core) and 950 MHz (memory). The machine was put through 3DMark05, where it ended with a world-record score of 45,474.

Please, please, fanboys -- sit down. Yes, everyone still knows the i7 is faster. Enough frothing at the mouth.
All this means is that now AMD chips are once again pretty damn decent. The fact that they were able to run anything for a length of time at that extreme overclocked speed is amazing.

totally agree with you mdm. although i would like to see some real world testing - games etc. - anyway this is really great news for AMD and i am seriously thinking about trying their cpus and platforms.
+1. Welcome back Amd :rockout: .
by: $ReaPeR$i think all these tests have been done already. there is been a whole avalanche of Phenom 2 reviews several days ago. Unless, of course, you mean tests at 6.3Ghz on liquid helium. But those wouldnt mean jack to most people. Still it would've be nice of them to run Vantage.

Nice numbers. does anyone know the launch date for this cpu.

Neither support ACC required by AM2+ Denebs to reach those speeds.
nor does SB600 and 700 but they have still pushed those chips. i thought ACC was built into P2
in fact they have gotten 3.7ghz on stock volts using a foxconn destroyer....

and they pushed it higher than they could using a foxconn 790GX mobo

unluckily the tester in this did not use DICE or LN2 on the 780a only the 790GX :(
780a has shown to be a better overclocker than 790FX in many cases. this was very true with B2 chips like the 9600BE being pushed to 3.6ghz something no 790 board could imagine
Impressive!
Let's hope that all of the PII chips can OC like that.

All i can is. WOW.
And all for a £240 chip compared to DDR 3 Ram, X58 Mobo, and a god expensive I7.
Well Done AMD.

cool, i always preferred nforce over ATI :p
And i think you have a good point, ACC is already built into the Phenom 2 so it shouldnt matter.
Not for everyday use but still very impressive.
by: cdawallwill still take my ta770 a2+ over the nvidia equivlant, i have managed 330fsb on this 6000+ b4 it stalled out(couldnt take more fsb) thats pretty decent, i havent gotten ahold of phenom yet, dont want a b2 since i run 64bit server 2008 and that damn tlb patch would ruin perf/clocking :/

by: Rebo&Zootythe NV equivalent would be 750a which easily pushes over 300mhz bus speed.

not to mention 780a which pushes over 400 ;)
Yep if You want Core i7 You must buy motherboard + RAM DDR3, so if You got AMD AM2+ then just buy PII and a good cooler and I'm sure with a 3GHz chip You Easily get 4GHz on Air maybe 5GHz with water cooling! And For the best performance/money ratio I think we have a good come out to AMD PII, of course if your dad is Rockefeller or one of his palls You can make a faster system with Core i7! But 4GHz 4Core System PhenomII is not bad for a little money! :toast:
by: cdawallits not the board thats holding me back, its the cpu, k8's enlarge dont like u to psu the buss to high, I have seen some stepings that wont take anything above 270 no matter how much u up the volts.

i had enought nvidia for now, the last 3 boards i owned for am2 where nvidia 550, 570 and 590, the last 2 where asus boards with SHIT bios (missing/non-functional memory options needed for proper ram clocking)
the 550 board lasted me the longist but the chipset also ran alot hotter even with active cooling then this 770 board.
im sure the board could take higher buss, but the chip cant, and im not gonna push insain volts thru a chip just to get a few more mhz, its 100% stable at 3.3 1.39 volts, any higher and 1.66 volts isnt even enough to get 3.4 stable (maby if i had water or an xp120 and high flow fan)
6000+@3.3 with 6gb ram is pretty decent if you ask me, specly at the volts im using, i may even beable to lower the volts(gonna try later tonight i think since its 14hrs prime stable as it is :D )
by: moto666intresting part i found was that for the price of the i7 board/cpu/ram you could get the amd cpu/board/8gb gskill PI ram AND a techwater cooler(xoxide has one for 137bucks) and still be cheaper then the i7!!! with that cooler 4gz or better shouldnt be to hard :D

duno, my g2 brisbain wont go past 3.2 and 315 buss, and i have seen plenty of 65nm amd chips that dont, now if you push insain volts into them, yeah u can do it, but Im not gonna do that to my chips, you may be willing to push 1.85v or so into a g2 but.....well i just wont torture my cpu's like that, I prefer them to last, from what I can see, you change stuff so offten it dosnt really matter :P

hehe this is true in the last 4 months i have had all of these and i have a sempron 3000+ on my desk A64 3500+ in my PC and 7750 making its way back from RMA.
intel
AMD's from the past
eww celeron.........
by: Rebo&Zootylook at the clock and that celly and its a very good chip smokes your AX2 as a matter of fact
eww celeron.........
by: Tatty_OneYes it will, But not expensive Tri-channel.
But I beleive socket AM3 will support DDR3?
by: DjJaklWrong, the mobo they were using is the M2RS which is a SB600 board and doesn't have ACC. I know because I sold mine to get the M2RSH which is the version with the SB750.
Did not know that... Interesting... Hopefully nVidia will fix that later on
But neither of that matters because the Denebs I guess have ACC built into the processor. From what I have actually seen the SB600 boards actually OC a bit better.
by: cdawallduno about that m8, the clock cant make up for the uber low cache, and the pentium dual cores have setup and helped overclock where faster in benches but where not even close to as smooth in real world use compared to an amd x2, corse if all u care about is spi and other benchmarks intels the only way to go.

by: Rebo&Zootyconsidering i have used a 7750BE, 6400BE, 5000BE, e1200, e4300 and several other chips the e1200 easily ran as good as the AX2's in everything. of course my fav chip to use this far was a phenom 9500+ and there was no comparing that to any dual core
