Phenom II at 6+ GHz: How AMD May Have Done It
A couple of weeks ago, at the AMD Austin Tech Day event, the company stunned the computer enthusiast community, by presenting to the press, the overclocking capabilities of the upcoming Phenom II X4 processor. The enginners managed to boot the machine at CPU speeds in excess of 6 GHz, 6.213 GHz to be precise. A close-up snap of a portion of the CPU-Z window showing the overclock, made its way to AMD's own photostream at Flickr, among other pictures related to the event.
The picture reveals the clock speed at 6213.6 MHz, bus speed at 200 MHz, FSB multiplier at an unreal 31.0x and resulting HyperTransport link speed at 1002.2 MHz. This would mean that they may have dropped down the HT link multiplier (normally 200 x 10.0 for the Phenom II X4 940) to 5x. We already know from previous reports that the vCore was set around 1.90 Volts, and that a copper pot with liquid nitrogen was used to cool the chip. The motherboard used, from the pictures, appears to be Gigabyte GA-MA790GP-DS4H, which is based on the AMD 790GX + SB750 chipset. For more pictures, browse through the photostream. More pictures could be added to the stream once the NDA lifts on December 14.

Yay!,(even tho i don't OC):)
Im sure the i7 would be quicker even on 4 threads, but its a big step forward for AMD who struggled miserably lately. hey binge, by the way, did you get that PM i sent ya?
Yeah I got your PM. My FS thread is updated all the time and is up to date. It's always in my sig.... Everything that is priced is what I have available.
So did you get the PM binge????
Googled translated and this one too (both were in Portuguese, originally).
Also, source of the 2nd link i posted above.
EDIT
Here's a preview:
For those of you interested. This was posted on XtremeSystems' AMD section today.And further info on his testing routine. Please note that he is comparing a 3.4Ghz Phenom I (oc'd 9850) to a 3.0Ghz Phenom II (940):
Here are results reported by Sampsa with Team Finland (Sampsa & SF3D). (NOTE:"3DMark05 & 06 CPU-tests were ok @ 6 GHz + We were able to run Crysis @ 6,1 GHz (2 loops CPU-test)"!!! :D) XtremeSystems.Org
Other then that, sweet!
Here is a streaming video of the event as well as other goodies: AMD Streaming Video
Cool stream, dude :rockout:
The Boston event was held last night and confirmed many of the results from the SF and Chicago events. This participant has reported an astounding result comparing Phenom II 940 to i7 965:SOURCE
