    Phoronix: Intel Core i7 3960X Sandy-E Takes Big Dive On Linux

    While the thousand-dollar Intel Core i7 3960X "Sandy Bridge" Extreme Edition processor can build the Linux kernel in under 60 seconds, this morning it took a nasty dive under Linux...

      Bent/burned pin on the socket? Those little bastards are very fragile and there are several reports of some motherboards (in the past at least) that already had some burned pins straight out of the factory.

        my overclocked core 2 duo system randomly doesn't boot whatever you spit to it, linux, windows..., the (software) uefi goes like kernel panic if it doesn't like the hdd configuration and so on... crappy motherboards is your problem...
        and like phoronix didn't have 10 news last day it needed one more...

          ..., I'm still loving the Core i7 3960X
          If I had a Ferrari, I'd love it too. Until I win the lottery, neither the aforementioned Ferrari nor a $1000 proc is worth it for me, however.

            I can actually verify this problem (I have a 3930k). I can't remember if I was able to get it installed, however. Pretty much identical stack track, symptoms, etc.

              please do a google search first before whining...

                Nope, tried it, still not booting.

                  Is the system using an OCZ Vertex 3? If so, what firmware version?

                    arch linux

                    I built an 3930k with an msi x79ma-gd45 and 4x8GB g.skill kit N82E16820231507.

                    I plugged drives into the SATA 3g connections (both 3.5" 7200rpm drives).
                    Running arch linux the only problems I had was the memory seating in the board.
                    For some reason these new boards seem to only have tension levers on one side of the ram, not on both.

                      nice box, how fast does your cpu run now and which cooler do you use?

                        1 question

                        Could it have anything to do with the cold boot?

                          I'm having a hard time overclocking this chip on Linux, I have to disable speedstep otherwise it seems the turbo never kicks in, and overclocking on Sandy Bridge-E is done through the Turbo! Since a /proc/cpuinfo | grep MHz returns 3299.992 no matter what I do with speedstep disabled I'm basically having to refer to Windows overclock temps to see what is happening even though it's the same overclock - http://i.imgur.com/5UAXz.png

                          On the Windows OC I had speedstep and all C States enabled, but no power management through Windows. This let the chip idle @ 1.2GHz through C State and on load all cores were at 100x42 for a 4.2GHz overclock.

                          On Linux, the same settings stopped the turbo kicking in at all, as my cpuinfo grep always returns 3299.992 I had to use temps to see what was happening. With speedstep enabled and without having any frequency scaling set up in Linux (cpufreq/cpupower) I was getting temps a good 15C lower which seemed to indicate a lack of turbo. By disabling speeedstep I saw my temps correlate to the Windows overclock. Whether I'm Idling @ 1.2GHz within Linux is anybody's guess, I've absolutely no way of knowing. but it would be nice :/

                            Any news on this bug?

                            Hi

                            I am planning to purchase the processor discussed here (Intel Core i7 3960X "Sandy Bridge" E) and would like to run Ubuntu 12.04, but I am really worried about the bug. Does anybody know whether this bug has been confirmed or resolved?

                            Thanks a lot!

                            Daniel

                              I had some serious serious bios issues with the 3930k system I built. Back in february/march I finally got a bios which allowed the system to boot cleanly every single time. I'm guessing the problems are related to ram compatibility with the memory controller.
