Phenom II X4 at 6.30 GHz, Runs 3DMark-Stable
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.

They are using very different gpus and 3dmark05 would be massively cpu limited hitting the overall 3dmark score. What would have been a proper indication is the cpu score on 3dmark05 vs a 3dmark05 i7 cpu score.
and even at full load you will not max out the QPI or HT on these chips this was easily proven several times when it was turned down and caused NO EFFECT
True that AMD can no longer compete with Intel's arsenal right now, but AMD doesn't really care about the word "competition" anymore, they just care about what the consumers need most, not enthusiasts. Sure, AMD kinda over-hyped us a bit when Phenom came out with nil overclocking, but so did Intel who decides to force people to upgrade their way to CPUs, mobo by mobo, which is insanely inconvenient for new builders who don't wanna keep on building. Sure, Intel rocks most of the time now that they've set the gap, but AMD is still good enough for gaming and multi-tasking as well as not screwing us over with incompatibility issues and overpriced processors with unlocked multipliers :laugh:.
That's a lucky number!
I am just impressed though that they benchmarked over 6Ghz. People can always boot and get a CPU-Z higher than stable benching. And with AMD Overdrive I could easily see 7Ghz CPU-Z verify real quick then tone it back down. My bet is it will happen.
