I just bought new computer top of the module of each part as follow:
main board GigaByte Intel P67
CPU 17 2600k
16 GB ram 1366Mhz
and SSD 120 GB hard drive connected in SATA 3.
i install win 7 64 bit and all work amazing and very very fast until ... i try to connect SATA 2 HD in the moment i add HD on sata 2 the computer become very slow , i connect 2T black WD totaly new and Grenn 1.5T WD in the moment i connect sata 2 HD all system start moving very slow.
I update the chip set all drives are up to date but nothing help me.
any one have any idea why its happen? any idea how to solve this problem ?
Is there motherboard a B2 or B3 revision? i.e. When did you purchase the motherboard?
There is a known issue on B2 P67 with the SATA 3Gb/s ports that can cause performance degradation. The SATA 6Gb/s are unaffected. Motherboard manufacturers and Intel are working to replace the B2 for all customers.
thr problem was another new HD that was conected to this computer, now all is working perfect... its look like http://www.urbanride.com charter a bus.... i hope WD will handle the replacement in a quick way.
