the M4 is the Systemdisk SSD and the Sandisk ist a blank SSD

Hi,

today I found new RSTe drivers v. 4.0.0.1040 at station-drivers.

Best regards

No RSTe 4.0 ROM yet, I take it?

Hi Fernando,

I'm using an Asus P5Q with windows 8.1 and a Samsung 840EVO SSD ( 250Go).

Intel O-Rom is version 10.1 ( can't be upgraded to newer version because there is not enough space in BIOS ).

What's the correct version with this config ? Should I go with Intel RST v10.1.0.1008 WHQL and not newer because of my ROM Version ?

Many thanks!

Just one more question: what's the difference between rst and rst(e)?

(e) like - Enterprise, meant for X79 board..

I would recommend 11.7.4.1001.
Anything older is using an Line-Based Interrupt (IRQ) which is most likely been shared with another component.
The new ones are all using Message Signaled Interrupts. See : http://en.wikipedia.org/wiki/Message_Signaled_Interrupts

As a matter of fact you can switch a lot of devices per registry to this mode, but you should avoid to do it on the old RST drivers because that'll lead to an unbootable system.
Just use this drivers (or newer) and you can narrow down possible hiccups or even enhance your performance a little bit.

If you're curious and want to try this for your other devices like videocard, pci-e port, soundcard, usb 3.0 ports (doesn't work with usb 2.0), etc. then look at this:

You can stabilize your system with that. A second rig of mine was kind of unstable with a videocard and no matter what i did over the months (different bios, IRQ settings as far as possible) this was a solution for spontaneous reboots, black-screens etc.

Beside that: 11.7.4.1001 is the latest one that won't give me that stupid shutdown / reboot bug with my ICH10R (P45-chipset).
It doesn't matter which OS and it doesn't matter which OROM i am using. (i'm on 10.1 now)
Only that with "powercfg -H on" it's more likely that my rig will reboot instead of a shutdown.
So 11.7.4.1001 is pretty stable for me, while offering very good performance.

Hi Fernando,

Thanks very much for all the info in your forums-eliminates a lot of guessing/searching.
Before posting the following I have tried several different solutions through 10's of fresh OS installs and many BIOS flashes with corresponding drivers as outlined in this and the BIOS mod forum
I am having a lot of trouble with my SSD's and trim-searched the forums, tried all the "modified tricks"; ie: modded OROM's and drivers etc. My specs are below. Thing is the modded OROM's put my BIOS clocks in severe disarray (especially xmp) and, in the end, do not give me trim support when used with the corresponding modded driver. I am not O/C'd (just xmp and Turbo-at default 3.9G). The absolute only way I can get trim support (as verified both by Windows 8.1 Pro x64 native defrag/optimize-which I use to activate trim and trimcheck-0.6-verified trim working after reboot) is to integrate the entire RSTe driver set; ie: both the AHCI and the RAID files from the driver pack even when I am only using the iastora driver-RAID0. If I slipstream just the iastora (RSTe) driver files trim support goes south no matter what I do-wierd isn't it? :)
After it all, once initialized trim works only upon reboot, not in the background immediately-much preferred, but, will take trim as I can get it, :)
Currently I am using the default F6_RSTe_v4.0.0.1040 WHQL drivers on BIOS Modded to 13.1.0.2030 SATA module and the lateat RSTe v3 Legacy OROM.-will flash all to v4 when it is available.

PC specs (I use BIOS 4206-anything post 4206 is a clusterf**k on sbe)
