PROBLEM:
Extremely low write speed on SATA disk.
Write speed is ca 2-3 MB/s (tested by copying a 400 MB file). Write speed is ca 55 MB/s according to SiSoft Sandra.
The computer is working normally until I trigger an intensive write scenario (i.e. copy a 400 MB file or install Ms Office). When an intensive write period is started then most of the computer freezes (must works, but most things can't be clicked).
I would really appriciate your comment what your guess would be for the cause of the problem, do you think this seems like a harddrive issue or a motherboard issue? I will attempt to try my disk in my brother's but I have a hard time to get time for that, and I would like to solve the problem asap (e.g. buy a new disk).
SETUP:
This week I purchased new parts. The old setup was very slow (P4 2.6 GHz / 2 GB DDR 400 memory) but I can't recall it was this
slow, however installing Microsoft Flight Simulator X took a LONG time (2 hours?) and it's only 2 DVD:s)
New CPU: AMD PHENOM II X4 955 3.2GHZ BLACK SKT AM3 L2/L3 8MB 125W P
(HDZ955FBGIBOX)
New Memory: OCZ TECH DDR2 PC6400 DDR2 Blade Heatspreader 800MHz 4G Kit (2X2GB) 4-4-
3-15 2.1V (OCZ2B800C44GK)
New Motherboard: GIGABYTE Gigabyte GA-MA790X-UD3PLK, GBLAN, DDR2, AM3
New graphics card: ASUS VGA-Card nVidia 9600GT 512MB PCI-E 2xDVI HDCP V-cool Heatsink DVI
to D-Sub adaptor PhysX CUDA (EN9600GT SILENT/2D/512MD3)
Old HD: Western Digital WD2500KS. 7200RPM. SATA2. 16MB cache.
Old DVD: IDE DVD burner
Old PSU: Seasonic S12 430W
Old floppy: Standard
Operating system: Windows 7 64bit RTM, using latest updated from Windows update. The OS was installed from scratch using the new hardware parts. I also tried with Ubuntu Linux 9.4 and experience slow performance but I did not document write speed.
Antivirus: I have tried both with and without antivirus
TROUBLESHOOTING:
- My SATA drive was in Native IDE mode. I changed it to AHCI (after installing chipset drivers), but no change.
- Installed the chipset drivers for the motherboard. There are no exclamation marks in the device manager.
- TODO: DMA mode or PIO mode? I can't find the setting for this.
- The motherboard has two separate SATA controllers: One controlled by the AMD SB750 and one "Gibabyte SATA2". I have tried connecting my harddrive to each.
- The File systems / write test in SiSoft Sandra goes on forever. Read test finished with ca 55MB/s
- Installing Microsoft Office 2007 took ca 20-30 minutes!
- Upgraded motherboard BIOS from F2 to F4
- Temperature: According to Gigabyte MB monitor the system and CPU are both at 40-43 degreec Celsius
- Enabled S.M.A.R.T in BIOS
- Checkdisk
- Downloaded HD diagnostic tool from Western Digital, the quick test shows "OK"
