We Overclock Phenom II to 4.9GHz
As you know, Tom's Hardware organized it's Overdrive overclocking finals in Paris over the weekend, bringing in teams from all over the world. The competitors benched and tweaked Intel's new Core i7 platform and achieved some significant scores and frequencies. But alongside Core i7, wealso had the opportunity to overclock AMD"s new Phenom II. You read that right--the next AMDprocessor that's expected to launch in January '09.
4957 MHz
Although AMD says nearly 6 GHz, we could not get - with the helpof Jmax - "only" 4 957 MHz. Remember however that the processor inquestion, a 940 Phenom X4 BE II, is running at 3 GHz in origin. We usedthe processor on a motherboard based on AMD 790GX (Gigabyte) with DDR2 and a cooling system with liquid nitrogen. At this point, based on what AMD tells us, the processor may have a higher potential, but it has an issue of locking at temperatures below -70 °C. To verify that the processor was stable at 4.9 GHz, we conducted some tests and it completed a SuperPi 1M run in 17,769 sec.


In practice, this new Phenom II in 45 nm seems very capable in terms of overclocking. Juding on what able says and how far we were able to push the processor, we're feeling fairly positive about its potential as a mainstream overclocking CPU. Air cooling should prove some interesting results. Look for some upcoming tests soon.

Wow, thats outstanding - so with a lquid nitrogen cooling and extreme overclock it manages to be around about 10-15% faster than my two year+ old core2duo running at stock with messenger, this window etc open - doesnt seem that impressive....
Wow, my Core 2 Duo E8400 overclocked to 4.4Ghz liquid cooled does SuperPi 1M in 11.127 seconds running Vista with several extra background processes. 17.769 seconds is SURELY a typo.
It gets worse than that if that's not a faked screenshot (which I can't really tell because the validator doesn't seem to be working) - my E6420 on a 965P-DS3 at 3.14Ghz happily completes 1M of Superpi half a second quicker. - http://www.upload3r.com/serve/161208/1229473866.jpg
I presume the Phenom II isn't terribly well optimized for these tasks as what I'd heard suggested it's not going to be too bad a chip.
superPI means nothing, it always runs faster on Intel even if compared to a faster AMD CPU (overall). Second, its single threaded - it uses only one out of all four cores.
