I've installed a new Samsung 830 which is blisteringly fast, 10 secs from windows to desk, however there's a problem in AHCI mode.

So, SSD worked fine (as the only sata device connected) in AHCI mode, but when I connected either my DVD or HDD to a sata port, the SSD took a very long time, well over a minute. The only way I've overcome this is changing back to native IDE in bios and not having AHCI. Is there a way to fix it so I can use AHCI? I believe in IDE mode, I can't now use a particular intel rapid storage file a friend told me to install that would have improved speed again.

Tried ''Onchip SATA Port 4/5 Type 'as 'As SATA Type', connected SSD to port 4 and also tried port 5, worked fine in both until other devices were connected. Then changed it to IDE as in my screenshot, still no difference. So I changed the one above 'Onchip SATA Type' from 'AHCI' to native 'IDE' and it all works with all devices connected, and all very fast. But it should work in AHCI, right? I believe there's no noticeable performance difference from IDE to AHCI other than hotplugging, so this may not be that important anyway?





 
try clearing the cmos with all drives connected but pc powered off,remove motherboard battery for 30mins,then load optimised defaults and re enter all your bios settings
 
I seem to be having a similar problem. Until recently, I was using Intel SRT to cache my mechanical boot drive with my SSD. You have to be in RAID mode to do this. I've since reinstalled windows on the SSD alone and have been trying to enable AHCI. The two registry values that are reccomended to be changed are already 0 and it still won't boot in AHCI mode, only RAID.

Any suggestions? Any help would be greatly appreciated.

(Sorry to sort of hijack the thread. It seemed silly to make a new thread with such a similar issue.)
 
@the op you cant use intel rapid storage drivers if on an amd board

@invisableprawn raid is fine as it contains ahci drivers also,it should work though in ahci
 
There is a difference between IDE and AHCI, AHCI enables the more advanced features like TRIM, it might be fast now, but in IDE mode it will suffer over time.

I was wondering about this as Ive heard the driver doesn't work with amd, but I thought that was only with some motherboards?

So in IDE mode TRIM is disabled, even tho windows 7 is the OS?

tbh im not 100% sure but i dont think amd boards have intel ports? im a noob with amd

ahci mode should work though,@ the op what data does the hdd have on it? old os or just storage stuff??
 
Thanks for the replies guys, sorry I haven't replied sooner, been very busy, including having windows installed. No really, double glazed ones, not Microsoft. :D I'll try out the cmos reset and maybe update bios.

Well at the moment, it's a new SSD and a brand new caviar black HDD, so nothing on them except new OS install on SSD. My RE3 HDD with all my important data, media and previous OS installation is out of the pc now and awaiting me to put it in my new usb enclosure.
 
See my post above - same issue when I installed a second SSD on the same SATA controller chip as a normal drive. Disappeared when I put it on another controller.

I've had a similar problem recently with my M4. It was taking ages to boot and even accessing the DVD drive. This was after a factory reset of the drive & rebuild, using Asus drivers.

I have found that these Chipset drivers worked a treat. Now boots in 20 seconds.

Wow, you are right!

I hadn't installed my chipset drivers yet but just installed the ones from your link. Changed back to AHCI and now get a fast boot. There's a 2 second difference between AHCI and IDE. Both go from 'Starting Windows' logo to desk in about 10 seconds. But using Restart-Time.vbs to monitor the exact boot times by rebooting my PC, I get these results, consistently.

IDE mode gets 'Your computer restarts in 27 seconds'.
AHCI mode gets: 'Your computer restarts in 29 seconds'.

Of course there's nothing much in it and I think the marginally slower AHCI time from restart to desk is due to this screen that isn't there in IDE mode


Am I best leaving it in AHCI, or gaining 2 seconds and going back to IDE? Do I need to reinstall windows having switched back and forth between AHCI and IDE? And finally, what about my motherboard specific chipset drivers which I downloaded the other day from Gigabyte, do I not need to install them now? It's a bigger file than the one I just installed. It's the middle one of these, and the top one highlighted is the one I just installed.

Glad your sorted

If its working with these drivers I would leave it as is it personally.

You don't really need to reinstall, because it just registry change to AHCI..

It's amazing how after after installing just a few drivers and half a dozen programs after my fresh OS install, the reboot time has already slowed down. Not too much but now it's 36 to 38 seconds from pressing restart to getting to the desktop. I hope it doesn't get slower, and I haven't even started any windows updates yet. I'm wondering what tweaks I can make in BIOS to reduce the POST time further? Maybe I should do a BIOS update as suggested earlier. I read on another forum where someone said a new BIOS dropped him from 34 secs to 18.

Do these benchmarks look as they should be for the SSD? It's a sata 3 drive and my motherboard is sata 2 so I know I'm not getting the best out of it, but I still was expecting HD tune to show better numbers, like 0.1 access time, a higher maximum and average transfer rate around 200+ MB/s and higher burst rate. Is it lower because of my motherboard and/or because of my cpu? Friend of mine has the OCZ Vertex 2 sata 2 drive on a sata 3 motherboard and he's getting much better HD Tune and ATTO results than mine. Given that neither of us are getting sata 3 performance, shouldn't the Samsung 830 at least match his results?

Hi guys, Ive been helping merlin with his pc, and I suggested him to use parted magic secure erase the ssd and start a fresh without unnecessary drivers being installed, as he is going to use acronis to back up the ssd when he's done installing updates, apps ect, to make fresh installs simple in the future.

But what was slightly worrying that performing the secure erase took about 20mins and Ive worked with 3-4 ssd's in the past and they have only taken like 1-5 secs. So have you guys performed a secure erase on a samsung 830 ssd and if so how how did it take?

The speed might increase when updates are installed, or when you have used he ssd as for a few weeks, as they alter after they have had a few days/weeks of every day normal usage.
