Edit: Now we have some information about nForce4 based boards, how about K8T890?
1. What kernel version do you have?
2. What kind of motherboard do you have and what chip (K8T890, nForce4...) does it have?
3. What kind of SATA/RAID chip(s) does it have? What kind of driver do you use and does it work?
4. What kind of ethernet chip does it have? What kind of driver do you use (name, propiertary/free) and does it work?
5. What kind of audio chip does it have? What kind of driver do you use and does it work? (in/out? 5.1? s/pdif?)
6. What kind of wifi chip does it have? What kind of driver do you use and does it work?
7. Do pci-e, usb, firewire and gameport work? Any tweaks needed?
8. Do cool n' quiet, power management and acpi work? Any tweaks needed?
9. Are there general problems with the motherboard? Any additions (like required kernel parameters)?
1. Linux version 2.6.15-gentoo-r1 compiled manually. No configuration issues.
2. ASUS A8N-Sli Premium -- nForce4 chipset (passively cooled).
3. nForce4 controller with RAID 0, RAID 1, RAID 0+1, and JBOD for both SATA II and PATA. Sil3114R SATA (SATA 150? unsure?) controller with RAID 0, RAID 1, RAID 10, RAID 5, and JBOD. Currently I am only using the nForce4 controller.
I am using standard kernel software RAID using mdadm on the nForce4 controller. Works beautifully and very fast. (see below)
4. nForce4 Gigabit + Marvell Gigabit. I am using only nForce4 NIC compiled into kernel (not module). Works flawlessly.
5. Realtek ALC850 8 channel. ALSA compiled into kernel (no modules). Loaded perfectly, first time. This chip reportedly works fine, but I have not tested it beyond seeing that ALSA mixer recognizes card and controls. I suspect that everything is fine with no problems.
6. No WiFi
7. PCI-e. Works great, right out of the box. Sli, too. PCI-e kernel parm.
USB -- 10 ports!! use EHCI and OHCI kernel parms. Untested, but kernel sees them.
Firewire - OHCI-1394 kernel parm. Untested, but kernel sees them.
Game -- Yes. Kernel recognizes it.
I expect all of these to work out of the box when I get to them.
8. Not going to use Cool n' Quiet. Reportedly works.
9. MoBo booted first time from installation disk (2005.1 AMD64). All was recognized immediately, out of the box. I generally selected nForce4 options in kernel when I compiled. Very happy with compatibility.
Re: Software (kernel) RAID
-------------------------------
I didn't even try the BIOS RAID, nor will I, as this is a Linux-only box.
Kernel RAID was straightforward, with minor gliches installing GRUB. Please use mdadm tools instead of /etc/dmtab. This makes software RAID a no-brainer. Enable kernel modules and you're home free. Works out of the box.
One caveat. Motherboard BIOS allows ordering of the controllers to be changed. When installing GRUB one has to first specify the original, physical controller order while installing GRUB in MBR. Then change grub.conf to the order specified in the BIOS. Also, GRUB install *requires* manual installation through the GRUB shell (specifying the logical drive!). Other than that, software RAID just plain works.
Re: Hardware Sensors
--------------
This is working via lm_sensors. I'm still fine tuning which kernel parameters are required. Docs online are for earlier kernels so I'm in new territory here.
Solved! See
this post
Motherboard has control of CPU fan and one Chassis fan. Other fans are uncontrolled. Sensors reported are the positive voltages, the two controlled fans, and three temp probes (CPU, Northbridge, motherboard).
Re: Overclocking
-------------------
In on-line reviews this motherboard is reported to have very good overclocking features.
I am not overclocking the CPU (AMD 64 X2 4400+), nor will I.
My memory modules are Corsair TWINX2048-4000PT, which are 1T 3-4-4-8. I am running them per Corsair specification at 400MHz and 1T 3-4-4-8. These modules are reported to be *very* overclockable. My system seems to be very stable in this configuration.
Re: Board Layout, Misc issues.
--------------------
Generally awesome, with minor issues.
PCIe SLI connectors are spread apart by two slots, leaving room for many supplemental GPU cooling systems, even in Sli mode.
Northbridge is passively cooled via heat pipe to a radiator next to the CPU. This leaves plenty of room for the PCIe boards. This chip gets very hot (untouchable). You'll want to make sure that air moves across its radiator. My Lian Li case (PC-V1000A Plus) does a good job of this with a 12 cm ducted case fan blowing directly on the radiator and CPU.
You'll want to put in two SDRAM modules, *not* four. With four SDRAM modules, AMD memory controller cannot handle DDR400 and falls back to DDR333. This has been widely reported. If you want top speed, your memory is limited to 2 Gbytes. This shouldn't be a problem for most people.
Re: Conclusions, Comments
---------------------------------
I am very happy with this motherboard. It is as close to perfect as I could want.
The Lian Li PC-V1000 Plus case is a great match for this board's features and does an excellent job keeping temperatures under control. This case is available in larger forms as the PC-V1200 Plus and the PC-V2000 Plus for those who require it. Expensive, but the best fit and finish in the business, to say nothing of quiet, cool, and awesome looking.
I generally eschew modules preferring to compile options directly into the kernel. The only modules I am using are for the sensors. On the very first boot with the custom kernel, all devices were recognized perfectly with no problems.
Word has it that an AMD A8N32 version of this is on its way to market, which has both PCIe (x16) slots running in full speed in Sli mode. It should be very pricey, but it could be the ultimate gaming motherboard, bar none.
I am extermely satisfied with this motherboard. In all respects it's a winner.
Issues: I wish the Sil SATA controller was SATA II. I'm not sure what it is, but I suspect it's SATA 150.
