Gigabyte DS3 slow hard drive read/write

I installed using the JaS 10.4.8 AMD-Intel-SSE2-SSE3 with PPF1 & PPF2 version on my Gigabyte DS3 rev 1.0 and everything works fine except for really slow read/write speeds. I get around 3-4 MB/s when I test with Xbench. I have my hard drive connected to the yellow port. SATA Native Mode is set to disabled because when it was enabled it couldn't detect it for installation.

 

I tried installing the Intel fix from the ds2-4pack.1.2.dmg but it just killed my install and I couldn't boot anymore.

 

Is there a fix to get fast hard drive write/read speeds?

 

Thanks

do this

sudo pico /System/Library/Extensions/IOATAFamily.kext/Contents/PlugIns/AppleIntelPIIXATA.kext/Contents/Info.plist

and on <key>ICH8 Serial ATA</key>

 

change the pci value to this:

<key>IOPCIPrimaryMatch</key>

<string>0x28208086</string>

 

and also make sure that the hdd is inserted in the first Yellow ports.

let me know if you succeed

I made the changes but the write/read performance is still slow. I plugged in the HDD to the purple port and the write/read was really fast but I can't get it to boot on the purple port anymore. Any ideas on other fixes?
