Old MB - P45 UD3P

Current - P55 UD5

On the p45 it says in AS SSD 103424 K - OK

On the P55 it says 1024 K - OK

Speeds for read and write are about half. Its in AHCI mode, am I missing something?
 
Yep, it uses the same chipset drivers as the old one;

* Product: Intel(R) Chipset Device Software
* Release: Beta
* Version: 9.1.2.1007
* Target Chipset#: Jasper Forest
* Date: March 02 2010
 
It does have this on the gigabyte site

are you running xfire? or usb3,i think that affects sata speed on p55 not sure now,could test by disabling usb3
be sure to use latest bios aswell
 
update - Is this correct -

I may actually have a solution for you to try. If the M4 is reporting UDMA5 it is operating in IDE mode.
Switch it to SATA/AHCI mode in bios, or try a different SATA port.

I have it plugged into GSATA0 which is in AHCI mode
 
Update - problem solved

It wasnt bios as I am now back to F4 as had overclocking problems with the latest

It was that I was using GSATA instead of normal SATA. I thought the GSATA was gigabit sata or something. Instead I read gigabyte uses its own marvel sata controller instead of the intel one.

In a normal port now and speeds are normal. Still don't know why it says 'not bootable' but it clearly is!
