Is native SATA same as ncq SATA

Hi follks,

On browsing
http://www.msicomputer.com/product/p...2-FIR&class=mb
in re MSI K8T Neo2-FIR motherboard

I found on

Code:


VIA® VT8237 Chipset
-  Ultra DMA 66/100/133 master mode EIDE controller
-  Integrated dual channel native Serial ATA/RAID controller that will supply 150MB/s and support RAID 0, RAID 1
-  ACPI & PC2001 compliant enhanced power management
-  Supports 8 USB2.0 ports. (Rear x4/  Front x4)

Please advice what is

1)
Integrated dual channel native Serial ATA/RAID

2)
native Serial ATA/

Is it same as ncq - native command queueing. I'm looking for AMD 64 FX motherboard with chipset supporting ncq SATA. Intel 915/925 can do the job but AMD CPU can't run on Intel mother board.

Please advise. TIA

B.R.

This is just a saying to make people think it does not uses a PATA to SATA bridge, so users can think they are getting a motherboard or controller with out the bridge which does not saffice performance at all.

NCQ (Native Command Queuing) is another name to queue a dozen jobs to the hard drive to access multiple files at once in a single head swipe. SCSI does this, so its not a new feature. NCQ works well when accessing OS files, web servers, and file servers but it will not help when accessing big files. NCQ can be later included with a BIOS upgrade, so you can pick any motherboard brand and model. At this time Linux does not support NCQ for PATA or SATA drives. NCQ has nothing to do with SATA but it is a good feature for SATA to compete with SCSI.

Hi Electro,

Tks for your advice.

Whether NCQ feature can be achieved with upgrading BIOS later, irrespect to motherboard

Please advice whether Linux distro does not work on SATA drive.

Linux supports SATA controllers, but not all of them cleanly and I suppose some are not supported at all at this time. I have an NF7-S 2.0 motherboard with an onboard Silicon Image 3112a controller. It's a very common controller on motherboards for AMD processors and it is well supported by libata (sata_sil driver if you build it as a module). Beware of the "Silicon Image chipset support" under ATA/IDE devices kernel configuration - this is *not* what you want. That's the old IDE driver which is buggy and abandoned. libata is under SCSI low level drivers.

Hi hw-tph,

Tks for your advice.

Is it to recompile kernel, uncheck the driver for "Silicon Image" support, re-select the driver for the controller of motherboard. If NO driver for the controller is available. then what can I do.

I'm interesting on following combination
AMD 64 FX 3200+ socket 939
MSI K8T Neo2 FIR motherboard
http://www.msicomputer.com/product/p...2-FIR&class=mb

VIA® K8T800 Pro Chipset

Does it support SATA without problem. whether recompiling kernel necessiated. What will be the ideal RAM frquency

Any comment. TIA

What hw-tph is saying. You will have to configure your kernel to only compile using SCSI version of libata not the IDE version of libata for Silicon Image controllers. Though this can be hard for novice Linux users.

You can use Highpoint controllers. They have open source drivers that works for 2.4.x and 2.6.x.

RAM frequency has nothing to do with Linux. RAM frequency is controlled by the motherboard.

According to my recollection on recompiling kernwl, there are options for selecting. My question was if I can't find what I need from the options then what can I do?

To my understanding taking DDR400 will be considered only a waste even the motherboard can support. If I'm wrong pleae correct me.

I already told you. Read my previous post again.

Athlon 64 boards need atleast 400 MHz (2.5 ns) memory. For reliability, I suggest 433 MHz (2.3 ns). The reason for this is the memory was designed on paper to handle 400 MHz but in real world conditions it will work with 333 MHz.
