P55 GD65 saturated SATA

[brenk]

Hoi All,

I'm having an issue with a p55 gd65 mainboard, when i connect my western digital green 1.5tb sata disk to one of the mainboard SATA connectors the system will beet fine. But when is copy a lot of big files (from USB disk or network) after 3-4 Gigabyte the SATA port seems to saturate the write speed drops from about 30mb/s to 1-2mb/s. The whole system is unresponsive due to I/O waiting. I can't find a single log message indicating any problems.

I've tried different cabling, different SATA connectors etc, all with no help.
When I hook up the drive to the (blue) SATA port from the JMicron controller the overall write speed is a little bit lower but that SATA bus does't suffer from this problem.

Anyone having problems like this.

Processor: Intel(R) Core(TM) i5 CPU        750  @ 2.67GHz
Mainboard: P55 GD65 (BIOS version 1.3)
Memory: 4 * 2Gb DDR3 1366Mhz.
Hardisk: WDC WD15EADS

What operating system are you using?

Are you running the SATA Controllers in IDE or AHCI Mode?

I am having a very similar problem. I have the specs below:

P55GD80 (Bios 1.5)
Core i7-860
Intel X-25M 80GB SSD (Boot Drive)
Seagate 7200.10 320GB (Data Drive)
DVD-ROM
DVD-RW
4 GB Gskill memory
Windows 7 Ultimate 64bit.

My initial setup had all of the drives on the Intel SATA 1-6 connections. I first noticed an issue when copying files from either of the DVD drives to my secondary data drive. My whole system would slow to a crawl. After many different combinations, I found the best performance by moving my secondary data drive to the SATA 7/8 Jmicron controller. It does not make sense why I needed to do this. Any ideas?

How do I enable AHCI for the Intel controller? When I went into the BIOS there only seemed to be an option for this for the Jmicron controller. When I enabled this, the system suddenly did not see any other drive besides the one connected to the Sata 7/8.

Also, why when I hook up the two DVD drives to SATA 7/8 (JMicron) will the BIOS see both drives, but Windows 7 sees only 1? Does JMicron only operate in RAID?

eman1777, don't hijack. Your system has different hardware and you only think you have a similar problem. Please start your own new topic.
