Phoronix: ASRock Z97 Extreme6

Those looking for an Intel Z97 motherboard that's Linux-friendly and jam-packed with features should checkout the ASRock Z97 Extreme6 as it should cost you less than $170 USD.

thunderbolt

Too bad I am AMD fanboy.
But does Linux support thunderbolt at all, I was under impression sh** just doesn't work?

Onboard gfx speed depends on RAM timing and gfx clock. My guess is that the fastest xmp profile was used by default and no standard ddr3-1600 timing with OC RAM. I dont think that using just optimized defaults is enough, some vendors like Asus even disable vt-t by default... Best check those settings, if needed using CPU-Z. Asus used another trick with board, after selecting a custom RAM speed the turbo mode is working in an all cores mode. Usually the highest turbo is only specified for 1 core at max speed with an i7-3770S but then all cores work at that speed, that is a benchmark cheat as well. With 3.16+ the turbo speed is exposed via standard /proc/cpuinfo, before tools like i7z are needed, you can simply run benchmarks with different thread settings and monitor the turbo speed. One other possible trick to cheat would be disabling the power restrictions for turbo boost. I do NOT think that asrock uses standard settings the way you tested the board.

I do like ASRock's Extreme6 line of motherboards. I own an FM2 Extreme6 board and my friend owns a Z77.
We've never had a problem with either boards, both boards have a ton of features, were reasonably (cheaply) priced and are built pretty well.

Asrock's newer motherboards seem to be a lot better. They used to be iffy. Now they are rock solid.

Thanks for the excellent article. Although, I only read the first page and the "Linux Compatibility" section which is my main concern when it comes to choosing hardware.

I didn't know motherboards even were an issue. What is it on motherboards that doesn't always work with Linux? Maybe I've just been lucky? I use a Gigabyte GA-990FXA-UD3 right now.

Ethernet adapter, for one, and only in some cases and only with some Distros. My new mobo came with an Intel 1218-V Ethernet adapter. Works fine under Ubuntu, but Fedora 20 could not find the adapter, nor can the latest SystemRescueCD or AVGRescueCD.

Intel has released a Linux driver, so I doubt that getting it working under Fedora is a big deal. I haven't tried to insert into a LiveCD environment like SystemRescueCD, yet.

Or, maybe it's a license issue with some distros. I dunno, I try to stay away from that part of the ecosystem.

I think the Linux compatibility issues suggested in the article are based on this quote:

The only real issue encountered with the modern motherboards have been the lack of LM_Sensors support for being able to detect and read the onboard motherboard hardware sensors (temperatures, fan speeds, voltages, etc). The ASRock Z97 Exteme6 is no different to the other Z97 motherboards tested at Phoronix. The ASRock Z97 Extreme6 happily booted up on Ubuntu 14.04 LTS without any issues, but was unable to detect any onboard sensors besides for the coretemp driver reading the Core i7 processor's thermal data.

It would be nice if there was a reference in the article to captures that Michael may have for the following Linux commands:

lspci -vvvv
dmidecode
sensors-detect

Then any user planning to run Linux on this and any other motherboards that Michael tests for Phoronix will have a much better understanding of the actual hardware found on the motherboard. The output of "sensors-detect" would be especially interesting since Michael claims to have issues detecting sensor chips. The "sensors-detect" command will show all of us what might be found by that command and why (or why not) "sensors-detect" does or does not detect any sensors on the boards that he tests.

On the other hand, maybe I didn't find the link to Michael's test suite results in the article? Michael, why not include these commands in your test suite, perhaps as an option so that those commands don't have to be run on systems that obviously don't have such capabilities? For example, if you ran "lspci" on a POGOplug E02, a very simple ARM-based device, it would not find a PCI bus not would it find any sensors, but other aspects of the test suite might run on such a simple device if it supported that "target" system.

Hi,

First time posting here, I can usually find the information I need, but sometimes I have to ask. So from browsing a lot, it seems that there aren't any motherboard with a z97 chip currently supported by lm_sensors, which means, if I'm not mistaken, no fan control.

The question is, how do the fans behave? I will buy a motherboard soon, and maybe plan to use watercooling. I guess the fans will be automatically throttled by the board, and that would probably be enough for me, but I want to be sure.

If the lack of fan control means the fans will run full speed constantly (as I remember hearing about), it kind of defeats the purpose of watercooling.

Can we get some more information about that specific point?

Thanks
