AMD Phenom II X4 955 Overclocked to 7.1 GHz

[topgear]

A group called LimitTeam managed to overclock AMD's Phenom II X4 955 processor and reach a record speed od 7.1 GHz.



A group named LimitTeam successfully overclocked AMD's Deneb 45nm Phenom II X4 955 processor (Black Edition) back on April 30, and submitted the results for validation to CPU-Z. During the process, the group used the Asus M4A79T Deluxe motherboard, dubbed as the Asus "multidimensional performance platform" featuring support for an AMD 140W CPU and the AMD 790FX/SB750 chipset. Additionally, the group threw in 4 GB of DDR3 memory from Apacer Technology and a ATI Radeon HD 4800 series graphics card. As a result, the group reached 7.127 GHz, beating the previous score of 6.7 GHz. However, LimitTeam didn't reveal any specifics in regards to cooling during the overclocking process.

Late last month, AMD said that it managed to hit 7 GHz in "extreme overclocking tests," more than doubling the original 3.2 GHz clock speeds enjoyed right out of the box. Apparently the CPU can be safely overclocked at home with speeds up to 3.8 GHz; anything greater will need "exotic cooling materials." AMD's product manager Brent Barry was noted saying that liquid nitrogen and liquid helium are best suited for high-overclocking environments, the former bringing the temperature down to about -140 degrees and the latter to around -240 degrees. Unfortunately, both solutions are somewhat dangerous to use. "This is fairly insane, science experiment stuff," Davis said.

Earlier in February, Team Finland reached 6.7 GHz with an early version of the Phenom II X4 955 chip using a similar configuration. However, neither LimitTeam nor Team Finland has overcome to the world-wide #1 score listed by CPU-Z. Clocking in at 8.1 GHz, a user simply named "duck" overclocked Intel's 65nm Cedar Mill Pentium 4 631 processor back on July 20, 2007 using the Asus "Commando" motherboard and 2 GB of DDR2 memory.

Now let's see the Core i7 975 XE's reply to that, HA!!

[amitash]

^Lets get the max stable OC on air cooling for core i7 (any series) and phenom 2 955 max air stable 24x7 OC and compare the benchmarks.

[anand1]

Yes it can be quite possible but of no use. This is so because one cannot handle the temperature dissipation when we start to run the CPU much above its rated speed.

[hellknight]

I think that its a new world record.. isn't it???

[comp@ddict]

^^For a multi-core, yes it is.

[4T7]

Duh I expected 8Ghz from this chip

[x3060]

hell, i wonder what are they going to do with this speed?

[dOm1naTOr]

world record,
wat else

[topgear]

I think I should bold some text. I did taht

BTW, The highest clock speed achived from a proc is 8.1 GHz using Intel 65nm cedar mill 631 processor - mentioed at the bottom of the 1st post.

Go here for the world's most high oced cpu speed records

it seems upcoming Phenom II X2 will have greater oc potential than X4, as all dual cores are better ocer than quads with same architecture and fabs.

[damngoodman999]

the AMD 955 proccy available for 13K , its beats the corei7 920 , but equals the i7940

AMD is giving nice value for money .

Phenom 2 940 BE is now costs 10K thats an another awesome report on the price .

[topgear]

Yeah, The amd phenom II 955 & 940 are some great VFM products & giving intel core i7s a run out of their performance ( & money too )

[dOm1naTOr]

cant beleive P2 X4 940 @10k.
but they shud considering lowering the price of X3 720. lots of people has a watch on it.
ill get it as soon as price falls below 6k for it. Now its some 7.5k i think.

[hellknight]

@damngoodman.. really?? does it really beats corei7.. can you please submit a link..

[Maverick340]

^^ I would like to see that too. I am building a PC soon and i was confused between Phenom II X4 955 and Core i7

[topgear]

There should not be any confusion.............
Just get the Core i7.........it's better than core phenom II X4 955
