New note April 3rd: I was preparing to send the SSD off for replacement, but the system locked again while running on conventional drives only. Back to diagnostic mode.
I built a system around this SSD, and it is giving me issues. And it turns out that I'm not the only one seeing this.
The system is rock solid in every aspect now (thanks to a new BIOS from Sapphire so I don't have to undervolt the memory on the 280X), except for an occasional lockup that happens randomly, even when the system is idle. Having gone thoroughly through every device, when I removed the SSD and loaded Windows onto a regular magnetic HD, the problem magically went away. Following that, I removed the AHCI interface via UEFI and loaded Windows on the generic IDE driver, and again, no problem. The issue is the SSD locking up the host controller via AHCI calls.
Sadly, this isn't a fix I can use, as the IDE functionality drops four of the SATA controllers, and I'm using quite a bit more than that right now.
The Force GS is based on the Sandforce 2281 NAND controller, which is supposedly a "mature" product, but a simple and common fault, even on Corsair's latest firmware, is really making me regret my decision. Still waiting on Corsair support, but we'll see how that goes. If I would have found this problem earlier, I would have RMA'd it via Newegg and gotten a Samsung, but I'm stuck waiting for them.
I'm curious if anyone has seen a filtering virtual interface driver that is Windows 8.1 compliant. I used one back in the XP days that created a virtual IDE controller that sat between the SATA host controller driver and the device calls, to get around early SATA device issues, but the dev group that made that is no more.

Dug around and found a direct AMD AHCI driver v11.8 (the bundled Catalyst packs saw the generic driver and refused to install the AMD software over it) and I have already seen a slight decrease in boot time (time to desktop is around 20 seconds, from 25-30ish before). According to AMD, this is the current build even in the latest packs; however I had to download it from Lenovo because AMD has chosen not to host individual drivers anymore, just the bundled packs that seem to not aggressively install anything outside of GPU software.
I will advise if this solves my problem.
Problem is not solved. Just happened again while watching YouTube.
Did some manual unpacking and found a more recent AMD AHCI driver embedded into a Catalyst installer (13.7) and there is in fact a more recent version. Installed and we'll see if that does any better.
Over 48 hours and still no response from Corsair.
Still having issues. Seems to happen most when the system is idle. I triggered power saving on all hard drives to 0 (never) in the Windows controls, so we'll see if that makes any difference.
Still no response from Corsair.
Well, Corsair asked me to run essentially through the same trouble-shooting issues I have already done, with no result, and issued an RMA.
New note on first post. Corsair SSD is not at fault.
I ran into one system that upgraded to a SSD and reinstalled windows. After a while of random 10 sec pauses I found a 400MB tiff image that was loading into windows backgrounds. Silly little things like that can drive a man insane.
It's a nightmare when you have all new top-end hardware, and something is wrong, and you CAN'T FIND IT!
