Sick Nick

Ive replaced my HDD with a 512GB SSD but kept the 24GB M.2 in there. I put the windows swap file there to reduce the writes/wear on my big SSD Given that Ive got 16GB of ram it shouldnt be used much anyway but at least its doing something. If I just remove it it will collect dust in the closet.

The ODD should be a direct swap, take out the old one and replace with the BD drive. Finding the ultrabay complete part will be tricky though, seems those are not for sale at all.

The 750/755 SLI setup blows a 660 out of the water, it's much closer to a 770 actually! Or the new 860 maxwell version should be comparable. That's the one Lenovo is using in the new Y50 models I believe.

The 42mm part is anoying, I'm seeing enough 80mm versions for purchase but I guess these wont fit?

bios update is needed for the ultrabay card indeed, mine also stopped working after updating to 8.1

I upgraded mine from 8 to 16, for daily use and gaming seems the same but when doing video editing with a bunch of tracks it makes a pretty noticeable difference. So if you do video editing or high resolution photo editing/raw I would recommend it, it's not expensive anyway so why not?

You can only disable SLI but it will still physically show bot GT755M's. I guess the only way to get optimus to work is to physically remove the ultrabay drive. Then again, does it really matter? It's more or less a desktop device anyway right so power should always be available.

AC all the way, I have one of these in my VAIO Pro and I'm getting 40 MB (yes, megabyte, not megabit) a second transfer speeds to my Synology NAS over the Netgear R7000 router. Pretty sweet so I cant wait to mod the BIOS on my new Y510p to pop in a 7260 AC as well!

Mine with the 755 SLI setup runs at about 87 degrees, pretty decent for such potent hardware!

Just got a Y510 so I'll give it a go, the N 2230 default adapter is pretty slow compared to 7260 AC I'm used to from my other notebook...
