re-installing W7 on an SSD - need to manually TRIM/GC or not?

i was wondering if i needed to run some sort of GC/FF-fill/TRIM util like the SSD toolbox on my X-25M before re-installing W7 on it (replacing mobo)

i know that W7 passes TRIM commands when inside the OS, but not sure if the drive formatting in the installation environment will trim the SSD drive if i choose to wipe it during install. i'm assuming it uses the same AHCI drivers in PE, so should be okay, but thought i'd ask.

thanks,
Leon

NO you do need to do anything. If you are cloning however, I would run a Crystal test to ensure alignment fell into place.
 
I was wondering this as well. I have the 128gb Western Digital SSD and I swapped motherboards and just formatted and reinstalled windows 7 64 ultimate. It seems like it might be a little slower, but the only way I would know this is because before, when I started Windows, I wouldn't even see the blue "welcome" screen, it would just go right to desktop... now I see about a 1-1.5 second flash of the blue screen. Any ideas on what I can/should do?
 
That is a good observation that TRIM is sometimes not passed during some operations (including bootup and shutdown), but I'm sure it's a non issue since Intel's firmware will sort it out using it's non-TRIM ways.

As flamenko mentioned, the only thing to really check is the alignment. If you're in any doubt, then during the Win7 install simply delete and recreate your partitions. Have fun.

Yes, let Win7 train itself to your bootup process. Also it could be the new motherboard's drivers. There is a built-in bootup analysis where you could pin-point what's taking so long.
 
windows 7 trims the entire drive when you format a partition... however, I do not know if it also does that inside the actual installer.

that being said, if it fails to trim the whole drive, you will see a temporary drop in speed that will clear it out by itself via trim, climbing to "new state" speeds as you use the drive, fairly quickly at that.

which doesn't really matter at all, since you can just install the intel ssd toolbox.. one single run of "Intel SSD optimizer" (manual trim) is all that you need.
