New Samsung 840 SSD very slow

Hi everyone, as some of you know i bought a new Samsung SSD, as your advice and reviews online rated them pretty highly, however, its sloooow.

i know it isnt meant to be slow and there is obviously an issue with my set up or something but i dont know what. i followed a couple of online guides on ssd optimisation and its still just as bad.

i just used a Z77X-UD5H in a hackintosh running a cheap Sandisk SSD and that was nice and quick, the windows logo on boot didnt even get time to fully load.
jut did another build on the MSI Mpower Z77 and i used one of my Crucial M4 64gb. Again the read writes are good (over 400) and the windows logo doesnt get to the end, the blue 'logging on' screen doesnt even show and then its desktop and fully loaded.

Both of these systems boot in sub 10 seconds!

my system does not. its very annoying because ive done nothing different, the only difference i can think of is my graphics card, but that cant be causing the slow speeds or boot.

my rig is in my sig -lol

and heres a screenshot of the 840's performance (please note this is not the 'pro' version but the regular 840)


can anyone help me?

Yea I second that ^^

The non-Pro version will have slower writes than read but I guess you know that because you specifically mentioned it being non-Pro.
 
yep, sata 3 (6gbps) and AHCI is on (its on by default)

i know the 840 will be a bit slower but not that slow. its something to do with my system. even my M4s were a bit slow. i have done clean installs and it doesnt help, but i put my M4 in another machine and it boots in sub 10 seconds. there has to be a bios option or something im not doing, but i dont even know where to start looking. ive just been on the gigabyte website and reinstalled every driver and chipset driver and its still no good.

turned off all unecessary option in the BIOS (3rd party controllers, 1394, etc..)
in your msconfig under boot how many processors in advanced boot options?
how many processes (task manager) are running at boot and after 10mins?
are you running onboard audio or optional?
power options is set to balanced or high performance?
 
NO, all the things you mentioned are on in the BIOS
there are no extra processes running as its a fresh install. All ive done is the optimisation for SSD.
63 processes are running including windows ones, i cant see anything that i could stop.
running a PCI audio card.
power set to balanced, but i thought that only kicked in once windows had loaded?

Im not even that worried about the boot times. Its just that i know the read/write should be faster. Even the M4 was quicker than that.

Do you want screen shots and if so, of what?
 
Try testing it with different benchmarks to see what kind of results you get. And, if you can, try doing a secure erase which should force TRIM on the whole drive then reinstall the OS. If the results are still the same then the controller might be defective. Below should be what performance you are supposed to be getting.

trim is enabled and its a clean install.

do you mean the controller on the board may be deffective.

I have used the Samsung disck magic benchmark as well and it still shows it as slow.
 
Sorry to bump but I really need a solution, this is just annoying me now. I just can't work out why my read speeds are so slow.
 
have you installed your sata 3 drivers ?? try and update them.. or reinstall them.. have you tried on the marvell ports ?
 
yeah they are installed, which ones are the marvell ports?

EDIT: so after pulling all the drives out and consulting the board manual I worked out which ones the Marvell connectors were. Plugged my SSD into the Intel port and my speeds are as they should be.
The Marvell chip should be just as fast though and I have 3 of the marvells own this board. It must be a driver issue. Marvells site don't list the correct driver though.

You are using the marvel driver according to that pic,so you must be using the marvel ports not the intel ones.

As you can see,I am running the Intel driver on the Intel port
 
I'm not using the Marvell ports anymore because they are too slow. The intel ones work fine.

Do you know how I can fix it so my Marvell ports run just as fast?
 
3rd party controllers never un as fast as the Intel ones.So you have switched to to Intel ports and installed the driver now?
 
i had this same issue on my g45 top sata 6 is intel next one down is marvel only the intel worked for me and i get sub 10 second boots now also get 530mb read and 135mb write i got my 840 today im happy with it :D
 
But how do we get those Marvell chips working, even a speed close to that would be good but 300mb on Marvell compared to 500mb+ isn't on!
My board has 2 intel 6gbps but 3 Marvell. I want to dual boot systems so want an SSD and mechanical drive for each OS, do I really do want to get that marvel chip doing what it's meant to do. Anyone got any ideas? It says my drivers are up to date, just reinstalled from the gigabyte website.
 
I know that but the Marvell chips shouldn't be running at sata 2 speeds. If the intel was 500 and Marvell was 400 it 450 then ok but it's not
 
its not that the marvell controller isnt working its just that ssd's in general dont work as well on them. Thats why its always recommended to run your boot drives on the chipset controlled sata ports and use the 3rd party ones for storage.
