SSD reverting to SATA 3gb

[Talostown]

hello all. I have a new evo 840 120gb drive that is a new windows 8.1 build. I have 2 other SSDs installed as well. All 3 are sata 6gb drives. When I boot and look at Magician, I see all the drives running in sata 6gb mode. When the Intel rapid storage driver loads, it initially tells me 6gb for all but after a minute or so, the evo drops to 3gb. I hVe tried different sata ports on the mb, different cables, different Intel drivers but with the same result. Only way I can get it to remain at 6gb is to uninstall the irst drivers and go back to the ms drivers which I rather not have to do. I am running the asus vii hero board. Any suggestions would be very much appreciated as it is driving me nuts.

Is ACHI mode enabled in your BIOS? It will let you know on the Magician main page in "System Information"

did you actually benchmark the evo to check the speed in case its just being reported wrong?

Thanks for the replies. Yes it is and I also read that this issue can be caused on ASUS MB's when hot pluggable is disabled so I enabled that as well which didn't fix it. Yes I benchmarked it with results for seq read/write in the mid 200's.

whats wrong with running the microsoft drivers?

far as i remember irst drivers arent actually necessary unless running raid

but one thing you could try--is fast start enabled?

Generally they do not perform as well plus when I run them I get the retired errors in the event log.

"The IO operation at logical block address 0x34b4b50 for Disk 0 (PDO name: \Device\00000037) was retried."

Starting to wonder if the drive is the problem. Was purchased less than a month ago. BTW, fast start is enabled.

try disabling fast start to see if the problem goes away

No luck when I disabled fast start.
