Thought I'd check in to let you all know that I rebuilt the system with a different motherboard, the Asus P8z68 Deluxe/Gen 3 and it's working like a champ. I haven't had a single crash in two weeks (I was gone for 2 weeks on business, I'd just gotten the system up and running a couple nights before I left).
Nothing's changed from the previous rig except I reinstalled my OS on a new SSD, the Samsung 830 Series MZ-7PC256D/AM 256GB SATA III. It's nearly as fast as my Corsair Force GT 240GB SSDs and is rock solid. I relegated the Corsair's to data duty, I do a lot of imaging in Photoshop and Lightroom and the speed having an all-SSD system is impressive.
The Samsung drive is amazing, has good numbers (549K/512K write/read on ATTO) and comes with a really super software called Magician that configures and optimizes Win 7 for you (superfetch and stuff that I didn't want to take the time to get educated about). Love it, one click and I've been good to go ever since.
I have had one crash, when I was trying to hotswap external esata HDD dock and it took down the SSD with it. Revised by plugging in before boot and no problems since.
The only quirk I'm seeing is my Corsair data drive blips out now and then. I'll be working in something, this time it was Lightroom, and suddenly the Corsair is just gone. I have to reboot to restore it.
Sometimes it will disappear on its own, others it stays up all day, I mean like 8-10 hours, and everything's just fine. There's no data loss or anything like that, the drive just drops out. A couple of times the other Corsair 240 also disappears.
The first Corsair is on the Intel 6GB SATA mobo port, #2 (the Samsung SSD with OS is on #1. The other Corsair is on the 3GB mobo Intel port. I've got the Marvell ports disabled.
I have all power settings set to Never. The system never sleeps so I don't think that's it, but maybe there's a bios setting I've got wrong. Or maybe the drive is funky and that's what caused problems with the earlier pro/gen3 system. Crystal Disk says it's sound but I haven't done any kind of thorough desk test (other than ATTO, which gives numbers consistent with the published specs).
Hope someone else has a solution, it's more nuisance than anything else but maybe means a more serious problem down the road. AFter my six weeks in Purgatory with that other board (which was repaired and returned to me so I'll be selling it) I'm a little gunshy about anything that pops up.
Oh: OS is Win 7 Pro 64 with SP1, fully updated.
thanks for any thoughts/suggestions.
