Hi, bought Patriot Blast 240GB but it's very slow on my computer. About 200mb/s instead of ~550mb/s read and write is even lower. Tried it on my friends computer and speeds are great, so is it problem in my motherboard? I have MSI 760ga p43 (fx). Any ideas?
 
I know about that but I couldn't find exact "sata transfer mode option". I only found some other options where AHCI is mentioned and enabled them. I'll check again tho.
 
Updated bios cause there is a "fix" for sata3, i have now 335 mb/s read and about 300 mb/s write. That is still low.
I have option in bios "extra RAID/IDE controller" , it can be IDE (these speeds) or AHCI (infinite restart loop).
 
sorry but i disagree--you keep saying it should be in ide mode

but show nothing to back that up

my ssds are in ahci and the speed is perfectly fine

and as ssd or crystal disk mark or plenty other benchmarks can test drives way faster than a sata3 ssd so dont know why you think only atto can do it

in fact atto usually shows higher scores because it uses compressible data instead of incompressible data
 
I reinstalled windows, double checked if it's AHCI on both options and now in CrystalDiskMark its about 425mb/s read and 310 mb/s write. Still not good but improved, I don't have any more ideas what to do. Contacted MSI, asked if this MB is bad for this...
 
I don't know sh** about all that, but just want to say speed increased about 100mb/s when I activated AHCI if that means anything in your discussion.
 


lol

even though you arent getting the full speed the drive is capable of in every day use you wont notice its still very fast

and the access times are more important which is what you will notice in every day use

 
Reboot loop is from not changing the setting in windows. I installed Win7 in IDE mode, changed a value in the registry, booted to the bios and THEN flipped from IDE to AHCI. It has nothing to do with if you have IDE ports on the board, but how windows "talks" to the drive. SSDs work best in "native" ports (Meaning those attached to the CPU, doesn't matter if Intel or AMD.) and in AHCI mode. They will work in IDE mode, but because IDE doesn't support newer things like garbage collection or hot swap, it's not as good. I haven't looked up your board, but if it only supports 2 SATA3 ports like someone said earlier, then they might be through a secondary chip and in which case your 425MBps read probably is the best you can get. When I plugged my 840pro into the wrong SATA3 port it couldn't break 350MBps. Considering you are using a 760 it's probably time for a new setup.

For those of you who did, watch the language. I don't care if you use *** to edit them out, don't use them.
