    Phoronix: Intel Preview: Z77 Motherboards Run Well With Linux

    Intel introduced their new Z77 "Panther Point" chipset earlier this month in advance of the Ivy Bridge processor launch. Questions have begun to pour in how the line-up of Z77 motherboards are working under Linux. Are there any Linux compatibility problems? Here is my brief statement on the matter for now after having already used two Z77 motherboards for a while under Linux.

    I don't have got Z77, but basically that chipset is only slightly improved from Z68, the main difference is the integrated USB 3.0 controller. Intel does not provide XP drivers for that btw, a bit unlogical as every other usb 3.0 controller has got drivers for that old os as well. Maybe it would work with other drivers there as well, no idea. Of course when you buy a new board Z77 chipset should be the best choice for OC. I don't think the sata controller part changed at all, the pci-e controller is in the cpu, so you get pci-e 3.0 support just by replacing the cpu not the board (assuming you get a bios update with ivy bridge support). If i would have got a new Panther Point board i would look if there is a secure boot option in there. But my personal guess is that only oem boards will have got this feature.

      3 monitor support

      Ivy Bridge should have 3 monitor support built in. Could you test that with the new chipsets?

        Michael fix spelling on page 1

        Michael fix spelling error on page 1:
        is:
        "The Z77 chipset can provide up to 14 USB 3.0 ports"
        should be:
        "The Z77 chipset can provide up to 4 USB 3.0 ports"

          Good to know there's problem on Linux, but it's not really a surprise, since it's basically the same chipset as Cougar Point.

          The whole platform is a disappointment. It was supposed to be 30% clock for clock than SB (remember intel's amazing 3D technology?), yet benchmarks show no difference from SB (2500k vs 3750k). There seems to be no improvement in power consumption either, even if intel labels the CPUs at only 75W, down from 95W. I was waiting to upgrade when I heard I could fit an IB CPU onto my P67 mobo, but it seems there's no reason to do that...

            I don't know what you're talking about... IVB is doing great!

              30% could be only the vga part faster (from HD3000 to HD4000), maybe 10% for the cpu at stock speed (i7). The HD4000 is now DX11 compatible, but Linux does not support OpenGL 4 yet (nor does the Intel Win OpenGL driver). It should be fast enough to play Rage @ 1080p (on Win). I really want to know when this will work on Linux (via Wine). If you already own SNB you can usually OC your cpu (without overvolting) and get the same or more speed than default IVB. It's therefore more reasonable to upgrade from Core2 or Athlon/Phenom systems than from SNB. It is useless to upgrade because of energy savings, the diff is so minimal as only the full duty energy consumption was optmized - definitely only at stock speed. Usually your cpu idles 90% of the day so you will not save much. If you use dedicated vga you can save even less energy.

                Not all GNU/Linux is Ubuntu

                Ubuntu has more tha 50% of GNU/Linux, it must be at every benchmark, but others too.

                Arch and Sabayon, LMDE, and Fedora and OpenSUSE are good alternatives and must be also be benchmarked.

                I am using Sabayon XFCE, I do like it a lot, fast as hell with a 1000 hz compiled kernel and TRUE Rolling Release.

                I also have other backup installations with mint12 and LMDE plus an Ubuntu PP at Vbox.

                I would like to read poroniz readers stats, probably there would e more arch and sabayon users than ubuntu ones, at least more than total ubuntu share.

                As you like to benchmark ubuntu a lot, please, benchmark the next ubuntu PP LTS vs current ARCH SABAYON, LMDE Fedora and OpenSuse. And probably ubuntu will not be the best one. But i think every other distro must adapt its PPA system in order to have more software

                  Of course, I'd be more than happy if that preview is far off. Maybe you know something I don't?

                    Thanks for your Preview, one question: So H77 or B75 is running fine under Ubuntu 12.04 LTS too ????? I will buy a H77 or B75 chipset based motherboard with IVB as soon as IVB come into the market in china.

                      There will be launch-day benchmarks on Phoronix of IVB under Linux.

                        Michael,
                        a lot of z77 motherboards use new (new to me at least) asmedia stuff for additional usb, sata and pcie to pci ports. Can you confirm that there is no problem with them under linux?

                          Basically intel only restricts some oc and raid features to certain chipsets. For oc support you should buy the z chips, if you want to be able to use a ssd as cache for a normal hd you need something with 7 at the end (not 5), but that seems to be a windows only thing. You can definitly use intel's (software) raid with mdadm on Linux as well (you don't need dmraid which has got no direct support for gpt partition tables - you see gpt partitions only when you manually call partprobe). There are more diffences in the number of sata 6 ports (1 or 2), native support for pci (does not really matter, if needed you get a pci-e to pci bridge on a board), amt support only for q boards. And even the number of usb 2 ports can be different. Just take a look there:

                          http://en.wikipedia.org/wiki/List_of_Intel_chipsets

                          None of those changes affects the Linux compatibilty or stock speed of a cpu. If you don't need sata 6 (or native usb 3.0) you can use the older h61 chipset as well. If you get a cheap 2nd hand board there is no reason to buy a new one as long you have got the latest bios on it with Ivy Bridge support. Just some vendors do not provide updates for every board. MSI seems to be a bad example in that case...

                            I have a DZ77GA-70K, has anyone actually managed to get linux to boot in uefi mode? (not legacy bios mode) Because I am having real trouble getting it to work.

                              running debian sid in a gigabyte z77mx-d3h, which i choose as to having less non-z77 features as possible (bad experience with asus feature ridden boards causing *way* more power drain than necessary)

                              usb, sata, etc all works.

                              fan control is huge no.

                              temp sensors seems right.

                              cpu freq scalling with a i5-3570K is wild. most bios can set the cpu to a specific multiplier, and/or to multiplier based on how many cores are under load. Then you add linux cpu governor on top of that... the result is a 3.4ghz cpu, with bios limit set as high as 4.5ghz, but stuck at 1.6~3.0ghz at all times under linux (even when compiling). But I don't think this is related to z77 but to the core itself.

                              most important to me is that nouveau supports the HD4000 just fine so far. performance runs circles on my old discrete 7300GT with the awful proprietary drivers. but again, irrelevant for a z77 or otherwise.

                              btw, unlocked intel cores for overclocking are the "K" ones, it was said differently above.
